RoboThespian: Chuck E. Cheese Entertainment Comes Home

Remember your eighth birthday party when the animatronic band at Chuck E. Cheese sang happy birthday just for you? Now you can enjoy this any day of the year with
RoboThespian
. The complete animatronic platform has been modeled in
Blender 3D
. Animating the robot is as easy as producing an animation from its digital model. Lip syncing is generated automatically, with the handles to the right of the model’s head controlling facial expression.
Using Blender as a choreography tools is brilliant. We’re hoping someone will incorporate this technique in their
Halloween shows
this year.

Shiftbrite Coffee Table

Here’s a project we’ve been wanting to do for a while. Over at macetech.com they’ve posted an
LED coffee table that uses a 9×9 RGB LED grid
. For the LEDs, they used the
shiftbrite modules we’ve seen before
. The table is capable of displaying pre written patterns as well as accepting patterns from a computer via bluetooth. They’ve set it up to connect to a twitter feed and display to a live cam on their site. Though we would love to reproduce this, we need a little more justification than “ooooh, shiny” for the funds involved. Anyone want to donate 100 shiftbrights?

10-bit Rotary Precision For Servos

[Antonb] added
10-bit encoding to a standard servo
. He’s removed the potentiometer, separated its shaft and used it to rotate a small magnet. By sandwiching an
AS5040 rotatory encoder IC
into the servo’s housing he can now measure the precise orientation of the servo horn. This is made easier by his tiny breakout board for the chip. If you want to layout your own PCB you can download
the EagleCAD files for this device
. Take a look at the final product in the clip after the break.

A Second Life For Dead Hard Drives

[AndyUU1CC] has put together directions on how he
built an Iambic Paddle out of some old hard drives
. The
iambic paddle is a device for telegraphy
. More specifically, it is that piece that you always see people clicking with their finger when they send a telegraph. We hadn’t seen an iambic or “dual lever” style before, but we now know that this is not an uncommon design. While it is ultimately just a fancy set of switches, we can’t help but be impressed with the looks of it.

Bring The Crane Game Home

"crane game",
"gantry"
] |
Everyone’s familiar with the quarter gobbling crane games. More often than not there’s a child nearby begging a parent for more quarters so they can try their hand at the toy-snatching claw. [Marc.Cryan] put his quarters to a better use by
building a home version of the crane game
.
[Marc] installed a gantry in an archway of his house. The crane trolley rides on this gantry and uses a spool to raise or lower the tether for the claw. Winning copious style-points, he used the case of an old mouse to form the claw. An Arduino controls the different motors in the system and a toy was repurposed to act as the controller. As you can see after the break, it’s more fun than the cinema-lobby version of the game and your kids can play with it for free.

Oscilloscope Doubles As A Serial Terminal

PC-based USB oscilloscopes are fast becoming all the rage. [Matt Sarnoff’s]
Terminalscope
takes the reverse approach,
adapting an oscilloscope into a full serial terminal
. You may have seen something similar before in the Dutchtronix/SparkFun
O-Clock
, but [Matt’s] project goes one further by adding a
PS/2 keyboard
port for full bidirectional
serial
communication, and with much sharper display resolution to boot.
The mostly VT-100 compatible Terminalscope is built around two
AVR
microcontrollers: an
ATmega328P
runs full-tilt to generate the video signal and handle serial I/O, while an
ATtiny45
handles keyboard input to avoid interrupting the ’328’s duties. Rather than vector trace each character, a raster-scanning approach is used: the beam follows a fixed X/Y path (like a television), while modulating the Z input (beam intensity) to form an image. The device can be connected to a PC via serial port or
USB-to-TTY adapter
, or directly to another microcontroller to debug serial output.
We recently showed an oscilloscope being used as a
multichannel digital logic display
. The Terminalscope provides
yet another use
for this essential bench tool and could nicely round out a “poor man’s” testing setup. The schematic and full source code are available for download.

More Cellphone Controlled Door Locks
|
Mike Szczys

"lock",
"wrt54g"
] |
[Tom Lee] and his colleagues just moved to a new office. The doors are setup like a security checkpoint with electronic strikes and buttons on the inside to allow entry. The button simply completes a low-voltage circuit, activating the strike which made it quite easy to patch into.
They build an interface board
with a small relay to complete that circuit. As we’ve seen before,
Linksys routers have plenty of extra room in the case
so there was no problem housing the new circuit in this tiny network device. Now [Nicko] and his friends can use
a custom app
to input an access code or to verify a device ID from a cell phone and gain entry. The door still has keyed locks in case of a power outage. In fact, the only change made to the system was the addition of two wires to the “door release” button as seen above. See the one-touch device ID authentication in the video after the break.
This hack is similar to the
GSM door entry
from last year. In this case, the phones are communicating with the door via web interface and not the GSM network.

The collapsing field should be able to flow through it and short out, yes? I’d think it wouldn’t affect Q2.

Not sure if it just got accidentally left out of the schematic, but a tip in case you didn’t know: the base-emitter junction of a transistor acts like a diode when forward-biased, so without some resistance it’s essentially a short.You should probably also put a small (few hundred ohms, maybe) resistor between Q1’s collector and +5V. The reason I say that is if the comparator and Q1 are both on, since the comparator is open-collector output, you essentially have a dead short from +5V to ground. Poof!That might explain the problem you’re having with startup..?Also, excellent work! I don’t hate Arduino, but it’s refreshing seeing that people still design circuits with ’em ;) In any case I hope I helped! Good stuff you’ve got there!",

Add Pause Button To The Atari 2600
|
Mike Szczys

[
"atari 2600",
"pause"
] |
We’re sure that if there had been a pause button on the Atari 2600 people would never have moved on to next-generation systems. Now you can dig the gaming relic out of the closet and
pause your Atari games
for some good old
om nom nom
.This hack is from the same person who pulled off the
Atari 2600 jukebox
. By reverse engineering the signals used on the
Onyx Jr.
, which has a pause button, the halt method became clear.
The problem is that the Onyx Jr. uses a different processor than the 2600. A different processor means a different pin-out, and now the clock signal needed to synchronize the pause cycle was missing. But eureka, an abstract source was found. The ready signal from another chip can be used to judge the state of the processor. The small PCB above now interfaces with the Atari 2600 in order to patch in the pause circuit.
[Thanks again Yuppicide, keep ’em coming!]

EVEN A ARCADEPower suppply in todays standards even if its a switching arcade power supply its crap unless its a Golden Tee type witch is just a ATX 20 pin connector power supply with the connectors removed and replaced w only whats needed in Game pcb.SO for a Atari 2600 power supply a great power supply is taken from a crap compaq pentuim II or5×86 motherboard keep chip for youre collection and harddrive memmory cd rom and pci cards then steal the power supply compaq spare power supply.to turn on most atx power supplys w out power on switch witch switches the outlet input and has no way of turning on exept the motherboard signal then VIOLA a easy way to power most power supplys is to short the 4th wire to ground you can just use a switch to short wire to ground and use it to turn power supply on and off at will if you short a power wire to gnd or short 2 lines together it willCROW BAR and shut down to reset just unplug till you hear a hiss noise DIE usually 4 seconds then when you replug ac line it will come back on most times unless you toasted it OS DONT SHORT 5v to ground the 5v line can exceede 20 amps in good power supplys and NO you can not over run the current to an input but a crappy NON switching arcade power supply w crappy ripple protection and ac leakage on the output can FUCK up any pcb running on Dc Cause it leaks ac .. I tested the power supply witch came w my arcade cabinet and found out the arcade power supply ” blue color ” even though it was a switching power supply it could not maintain 5v it swang all over the place and also leaked AC on the line I looked at it w a scope and found all kinds of static on the line and when i turned the bathroom flourecent lights on the started in the bathroom light made a SPIKE on the power supply witch never showed up on the compaq ATX power supply so my point is if you want t power supply for 5v or 12v or even 3.3v use a computer power supply and yes you can use the 24 pin ones you just dont use the pins UNLESS ITS A computer motherboard like a trivia Merit pcb then its just a computer running a special dos! anyway back to the power supply here is the pin.its pin 16 look here.http://en.wikipedia.org/wiki/ATXanyway I have used computer power supplys for years now I discovered pin 16 witch i still call pin 4 cause i never looked at the actuall pin number till i looked on wiki and found out the pins are actually numbered on the connectors sometimes and pin 4 is actually pin 16 so i was wrong anyway ..hook up pin 16 to gnd or a switch then hook the black any black wire I usually rip apart a computer fan bender gender bender adaptor for computer fan supply and snip off the output and just take up one drive connector and use that one incase i want to reuse the power supply i just butt connector or scotch lock it back and use on computer . mostly i never use power supplies i butchared for computer again ..they are great and put out 5v 3.3v and 12v all at the same time and the bigger the wattage the bigger the 12v rail and the 5v rail is.you dont neeed more than a 100w power supply for Atari even a 90w power supply for a mini pcb will work.the cool thing about using a ATX power supply is if you short any wire out it shuts off w out blowing a chip up most of the time it has saved me from ruining many things testing them before soldering power..***********************ok rant over back to Atari now************************on the 2600 if you make a 2600 witch has a blown chip into a flashback II mod it works great just leave the whole pcb on place and remove the rf modulator and the rf cover and the chips or you can keep them there if you want for storage anyway you wont need any of the parts EXEPT the power section leave that there remove the rf cable and use it in youre stereo for a long run! yea a free cable!! anyway/flashback I used the b/w switch for built in and cart mode i seperated the foil from the motherboard on the black and white color selecti ion switch cause jumper on cart jumper off on cart and jumper on for built in so having 2 selections on a dual switch single pole one moving part and double pole single moving part single throw double pole means it has two switchis lines on the left i used up to turn on middle conneciton on left sidecommon not touching right common not connected on foil either so it was isolated from the pcb.i hooked the left common to A10 on the cart ridge connector the cartridge slot and the cart slot i used ide ribbon cable to connect to flashback II rev the one w the easy to find jumpers the other flashback ii i trashed getting mad and the fact that i could not find the connections anyway who cares i got it cheap I now have a extra flashback case .. ok the common on the left goes to A10 on cart slot and the top line on the left side goes to flashback where it said to go on mod instructions then the right side common goes to memmory on a10 output from built in memmory from flashback jumper point solder piont to middle wire common on right side of b/w switch then the top wire on right b/w switch goes where the built in memmory a10 line goes on solder point so in other words you turn on built in memmory wilst turn ing off the cart a10 line so you unhook one line and hook a nother thats why you need a double pole double throw switch but what they didnt know is###############################################$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ATARI 2600$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$################################################switches like to slip and connect both lines before actually sliding into one or a nother postition so in a sence you can have both the built in memmory and the cart on at the same time this is caused by the fact that the built in memmory is still connected when the cart gets connected and is still running on the built in memmory when you slide down to get built in memmory the cart is still connected.you have to turn on unit in the built in flashback memmory mode 1st then start a game like ADV then switch to cart mode or it locks up before starting cause NES on chip has to load 1st before it can load a 2600 rom..weird how they used a nes on chip for a menu selection and NINTENDO HAS NOT gon after JACKS PICIFIC OR BASIC FUN for using a nes on chip on the Flashback OR DID THEY DO IT ON PURPOSE JUST TO PISS US OFF..hmm who cares i already have a flashback w cart mod..a fun thing to do w a modded flashback that takes carts is to start asteroids then flash to cart real asteroids and watch the only thing that changes it the rocks shapes..a nother fun thing to do is swap betewwn built in adv and REAL ATARI CART missile command it does weird things like missiles smart bombs go UP and score keeps going up automaticly the smart bombs get scary LOUD!!a nother cool thing to do is start caverns of mars then swap to snoopy cart..Also a cool thing i found is PLANET PATROL aAPALLO cart has a 7400 and a 2732 in it ! this is the way to make youre own homebrew carts I got lucky and was at pawn shop and i said have any atari and they said not all the time but from time to time and cause of pawn stars sometimes we get some Atari collections pawned and sell carts off till there gone i said whell what you got now they said come over here by the jewelry cabinets and look under neeth the diamonds and watches there was long big drawrers with NES 8bit carts galore cool and sega 8bits too and super nintendo too then whooly crap my eyes lit up a whole drawer of ATARI 2600 carts loose filling the whole drawer I said ok how mutch for that that that and how mutch is that she said hmm my carts I was like crap price just went up cause she saw how exited i got when i saw drawer full of atari games she saw $$$ I saw fresh pcb to chop into homebrew anyway the cart looked easy to ram a 2732 into cause it had those spring door open things for the cart door dust cover lock witch i liked cause making a homebrew always screws up that door lock thing and to remove the dust lock requires unslodering the whole connector and removing the screws from the ceramic connector not worth it ..anyway when i got home the game sucked so i ripped it apart cause it was worth $4 on ebay exact price i payed actally i paid TAX so it was more anyway I decided to ripp it apart to see what kind of chip it had and to my exitement it was using a 2732 and a 7404 a 74ls04 forget the ls crap its just a number the 7404 part is the important number..so i saw that they only used 4 lines on the 7404 so i got a 7404 from the arcade pcb pile and chopped the unused pins off then took a old atari pacman pcb witch the chip was blown and i unsoldered the chip snipping most of the pins off in haste to get my homebrew hackomatic III modded cart to run on real hardware and added a socket to the unmodified atari 2600 pacman cart pcb then I scratched the nessacary lines off the foil on the pacman pcb (2600) version and ran jumperes to match the pinouts of the apallo cart to the 7404 then hooked the 7404 up exactly like the apallo cart had it then i eeprom burned the 2732 using mywilliam parralell $15 ebay eeprom burner i just sent the file a1.bin to the atari cart as a bin file the trick to the william burner is to use a power pack not a usb cable for power to the pcb the usb does nothing but supply power so thats dumb and i used a 24v DC power supply and it worked in the 12v jumper mode anyway the eeprom programed and worked fine then i hooked the socket to the pcb in the connected to the 7404 like the apallo cart had it hooked and beeped the pins out using volt meter ohm beep mode and checked that the lines going into the atari went to the 7404 and the 2732 like the apallo cart had it hooked and ran the jumpers scratched lines on foil to make it same its actually easy once you have a working model to use ..the 1st attempt worked i just took the apallo cart and swaped the original game chip w my eeprom burned one w a1.bin my hacked version of asteroids witch i changed the look of the rocks and the (c) page on the begining of game useing hackomatic III a program where you load a 2600 rom then click on boxes to changed graphics then save the rom as a differnt name . then burned to 2732 w william .97jburner and put my rom into 2732 and into apallo cart swapping out the apallo game witch sucked then I kept the game I dont know why i could use the 2732 for a nothe homebrew but have lot of blank chips from bking II ..it worked in the flasdhback II any 8k rom will work on a 2732!!!! this is good news cause hackemis a 8k rom so i took the other homebrew cart witch i bought online witch uses a 7404 but a longer eeprom 2764 chip i subpose i could use a 2732 but dont have any longer chips w that many pins and I dont care anyway i burned asteroids my version snoopy was already on one 2764 cause thats the game i bought the modded cart for then i burned combat rock cause sometimes i just like that song also i made some custom indy 500x maps and a vareint of cx tank modded remodded maps and i burned the new gun fight .. and they all booted into the flashback II also the pacman pcb 8k chipson 2732’s worked too I tried the 4k rom on a 2732 and it worked too .i guess the 7404 HEXINVERTER chip bank switches to fake the atari the a10 line in the corect order like a atari custom chip oututs the a10 line..so if you want homebrew eeprom help see atariage and look up eeprom and homebrew i have a lot of infomation there and pictures of crockrocks..as far as the pause chip design i like it is there a silk screen pdf somewhere cause i know someone who makes there own pcbs… I wouuld like to incorperate that into my 2600 flashback..I also fixed 4 atari’s from ebay .one had a 7405 voltage regulator and another had a totally shorted power input jack someone was using a huge woodburner soldering iron and blobed the whole connector to gnd. I fixed all 4 atariesone had a blown rf mod a pal version shorted on all pins on the rf chip so i took rf mod from my blown arcade II case yes ill fix it later..and the other one was a 6 switcher yellow graphics on sticker and was pal version I swaped out us mod ulator and viola it worked the other one needed cleaned and switches were toast had to rebuild them and luckally that week my muffler blowed out so i had some tinfoil ducktape on hand to gnd the switches panel like NEW.. still have 2 or 3 real 2600’s not modded to flashback II but one is modded to rca outs not as good as ben heck’s good mod but works good enough for me..flashback I Iplays Pitfall II but graphics look like chunks and you get stuck swiming all over the place its like playing atari threw a SSAVI zenith box scrambled its hard and unplayable whell not enjoyable anyway.. enogh with the anyway..I did however get the flashback II fully wired inside a 2600 case and the b/w switch is cart built in so the b/w says BM and up postition says cart I snipped up a old non working case sticker to say BM swithed the w upside down to look like a m and then somehow made cart out of the left over sticker chunks.. I ALSO used the ch 3 switch since non needed on flashback II for the B/w switch on flashback II … so all the inputs work.built in cart switch is black and white switchch3 ch4 switch is b.w switch for flashback and difficulty switches are hooked to gnd when on and off when off and reset select work and the power is same always taking power from power pack as to load it and when you turn it off the power to the flashback goes off so it still takes power from power pack weird cause when you turn it off the cap stays on for a while about as long as it takes you to read this extra line of crap i wrote here to get you to .. its off now .. then you sometimes have to remove phono plug to completely kill the capacitor and reset to ADV BLUE HOUSE SCREEN ON flashback II.also dont forget1 9 7 2down 1 timesup 9 timesdown seven timedup 2 times or is it the otherway aroundup once down 9 times..anyway you know when you get it right cause paddle menu comes up.sometimes when i swap between built in and cart it saysthis area is intentionaly left blamkor something like that but one word is spelled wrong!.I thought oh crap i toased it for some weird reason my freind WAS there and he said you did it now he said as usuall why do you always have to turn it on and off so fast ..LITTLE DID HE KNOW IT WAS DESIGNED TO FLASH BACK BETWEEN a10 and built in memmory and i told himI was NOT POWERING OFF AND ON AND SHOWED him the inside and said GET THE F out what the hell is that rats nest inside the atari I said watch this I unplugged the power pack to let it die put it back into built in mode and plugged it in w the TV off so he wouldnt see the flashback MENU then swapped to cart mode when he wasnt watchingthen said look atari he was slightly interested then is said watch this he said SO its a atari he said i had pong before you were born I said but watch this I swapped back to the flash back menu and he said WTF get the F_ck out what is that how did you make that he said i said I took that MINI plug play atari and modded it into the 2600 case to use the cart slot and power and all the switches he said WOW WOW ow wow YOU ACTUALLY MADE SOMETING that works I said I do that all the time but noone sees it cause its all inside stuff like reparing a power supply noone sees that..anyway he said youre lucky it didnt blow up when it said this area left blank intentionaly I said I know I thoght i ereased the built in games from the nes on chip.. luckally it went back to flashback menu then I holeded the reset and powered on once and viola a test menu cool then holded select and a differnt menu came up.also inTHe FLASHBACK II version of ADV II you canplay game and when you get to maze turn color to b.w mode cause you can now SEE its child mode like having unlimited match in haunted house but adv II is not same game..I appoligize for the rant..when you save the rom mak eshure you change the name of the .bin file not to match the original file youre modding or you might screw up youre original file and not have a back up to go back to to reverance what the original rom looked like.it took me 3 months to find Atari(r) Asteroids(r) 1 9 8 1 version w (c) at the start of game to compare to my crockrocks homebrew witch is not for sale and is for informational and educational purposes only…...ENJOY homebrew and enjoy HACKING away atAtari(r)Atari 2600(r) or any thing you hack or mod or homebrew..also you can play tank in stereo if you remove one pin and unjumper it from the other pin and then hook both pins to atenuated preamp and then run to stereo DONT HOOK DIRECTLY to chip pins w out resistor cause it might blow amp anway atari originally was going to put speakers in those holes under the case and make stereo tank but somany carts were made avalible by the time atari released the 2600 that they must have thoght witch was good cause it did tank wore off cause the fact was the fact that you could swap carts was what made the atari 2600 so popular more than the other titles cause the Atari corp knew what the they were doing when it came to us NTSC television scanlines and hmove and the pokey chip and antic chips and were geinus when it came to television blank lines and programing a video game that used the same telecaptions as an original TV program signal would so the tv just locked onto the signal as if it was a REAL tv program making the frame rate of the atari like 35 35 like asteroids in mame witch is 35/35 out of 35 lines not skipping any scanlines..this makes atari 5 more lines than REAL tv witch makes anyone watching atari who likes and liked video games and watching tv more interested in atari than tv cause 35 lines is more than the tv program witch only had 30 lines per second thats why every one loves the atari2600 and the color burst pokey and the 6502 proccessor was great at producing color burst on the tv like missile command had that infamus color burst rainbow of all the colors shifting threw every color the atari had like 256k color 254 colors are avalible on the atari in like setcolor x,x,x boarder inside the boarder and the font color witch makes the atari 2600 have the same colors as the atari800 but was accessed differntly than the setcolor but there is a demo cart rom emilation rom witch you can pick same amount of colors as atari800 you just cant get mode 8 you can get mode 4 3 and mabie mode 5 graphics on 2600 but certianly not mode 8 or 11 modes..the fact that the atari had sutch good grpahics and was capable of taking bank swithed carts was still better than the nes 8 bit and if you think about it who did nintendo copy when they made the 8bit nintendo home entertainment system they copied the atari800 they just used a midi chip and a differnt sound chip and made there own operating system but if you look at the nes the only differance between the 2600 800 and the nes 8bit is the FONT SET I bet they took a atari800 and changed the font charactor set 10k rom to change the fonts to look like super mario score fonts and then just changed the sound canvas to use a soundblaster type opl chip then went ape crap insane with there (r) (c) pattented lockout chip crap and there SEAL of Quality then price fixed TETRIS and fought Tengen Software witch they probably started in the 1st place just to sue them and settle price fixing Tetris and chomped it so we thought NINTENDO HAD come out with a new video game but really probably just chomped Atari800 os onto a chip and changed the sound chip and is probably running a variant of a atari 800 on a nes chip so who stole from who we will never know because jack T died with the secret that nintendo probably paid him off as whell as microsoft paid him off to run Atari and Commodore into the ground so Microsoft and Apple were the only computer companys and NIntendo was the Arcade company left if you look at the nintendo grpahics and atari graphics and how the nintendo memmory works think about it if nintendo took the 10k atari operating system ROM out of a atari800 and rewote it to use a differnt sound chip and a differnt grpahics chip w a differnt charactor chipset(TV TYPERATOR FONT) you would see the only differnce is the game runnig otheriwse every computer is the same all 256K chips are 256K at about 10 nano seconds..48k on the atari800 was probably max you can get 256k but what can you do w it its to mutch ..on the nintendo 8bit you can emulate the 2600 on a flashback II or even make a keychain w out the pokey chip sound chip and have crappy nes sound…..DO THE MATH NIntendo stole the 800 and rewrote the os then sold the NES 8bit Famicom w a crappy CART CONNECTOR witch atari should have suied nintendo for stealing the V C S Video CArtridge pattent system pattent witch they could have one but were busy having jack trimel f_ck(screw) the whole atari company into the ground just to sell out to bill gates who is now being fU_ED(screwed) up the ying yang(butt) cause he is going to regret making windows 7 and lieing about the date on xp install so that you have to upgrade to windows 7 witch you dont you can change the date in c-mos low level format and reinstall a fresh copy of xp in 2007 then change the date after it loads then upgrade to windows 7 after formating windows xp away to fresh partitions not formated then windows 7 loads its a LIE to get you to buy a bundled computer you dont even need you can upgrade any computer to any version of windows expet some cant do 64 bit and some can ONLY do 64bit ..anyway bill gates is being F_ed(screwd) as we speak not by APPLE(r) APPLE i_od i_ad and i_p_onecause guess what Motorola is making Google(r)phones witch are more fun and you can zoom the same way as apple(r) phones do you can not copyright a zoom feature a lcd manafacture came up w all you did was try to corner a zoom feature we already thought up before the iphone came out it was a sprint at&t t-mobile verizon next tell crock from the get go that phones would not zoom like iphone would cuse they had to make shure ipones didnt get viruses so they had to make an operating system failsafe from viruses so when it reboots it cold starts like an atari you know the cold start acronym came from the Atari manual for Atari800 from the factory notes a warm start is a reset that just reboots w out killing off memmory dumps but a cold start is like turning it off and on again cell phones do this when the tower gets overloaded from google cache i did this with my 3985i phone nokia in b/w text only mode browser google text only cache google cahce i ran the tower out of disk space!!!!!!!!!!!!!!i was like awesome i finnaly used up the harddrive space on the cell tower looking up seagate harddrive settings using google cache text only searches and went past the goooogleplex of numbers google had on seagate drive information .then i called verzion and told them i locked up the sprint tower and they tried to say its a verizon tower and i told them crock its a uswest tower ! sticker to prove it anyway uswest now qwest used sprint for there cellphones so this tower had a uswest sticker on it cause they put it up that doesnt mean its not a sprint .pcs tower w .pcs 3g on it now it has 4g 4g must be cdma and gsm at the same time..3 g hasphonenumber@vzw.3g.comis a nokia #data# mode sitethere are3 serversand 2ip’s per each serverso if you use 1 server you get 2 ips at same timeif you have two active phone numbers nam1 nam2automatic a being name2 and automatic B being nam1 pphone number you can use4 ip’s at same time! hmm thats why cell phones in 3g are fast and even faster in 4g cause 8 ip’s at the same time is like 1.5m x2 3megabytes per second thats fast up and down stream faster than a dsl in old mode..so google phones are better than the iphone cause the graphics are the same and ebay searching all you do is scroll scroll scroll and no activex crap adds to slow you down..its awesome.and you can now emulatie atari2600 on a phone ,,",

This
beautifully crafted grinder
would make any machining enthusiast salivate.It features a fixture for holding your work at any angle or orientation to the grinding wheel but the slotted bed also allows for other attachments to be used. Two of the examples shown in this highly detailed (machine porn) writeup include sharpening bits and light surface grinding. There’s not much more to say because the pictures speak for themselves.

He does describe a spindle he built elsewhere on his page, I am assuming that he used that. Reading in mechanical translation, I can’t be sure of how he addressed the various problems that make grinder spindles so expensive. (a single replacement spindle can cost $2k, a simple wheel mounting insert $200)One thing that makes me question the accuracy of the thing (besides heavy use of aluminum) is that there is no evidence of fitting the sliding surfaces. (this is normally done with marking compound, a surface plate, and special hand tools. It leaves a distinctive finish.)It definitely tool p**n, despite my quibble.",

Looping Foot Pedal

This guitar pedal
can record, playback, and modify samples. [Colin Merkel], also know for
his work on electronic door locks
, built this to replicate some guitar effects he heard in recordings. By tapping the button at the bottom with your foot the device begins recording. Another tap stops the recording and starts the loop. That’s where the rest of the controls take over, with settings to adjust the speed of playback, volume, and the type of playback looping. The video after the break gives a great demonstration of these features.
[Colin] built this around a PIC 18F877A with a 256k RAM chip to store the sample. There’s a bunch of other components that go into this and we’re dumbfounded that he built it on protoboard. This would be a multi-breadboard prototype for us and we wouldn’t think twice about laying out and etching our own PCB. He admits that the point-to-point soldering stretched his skills to the limit but he doesn’t say how many hours it took to get the circuit up and running. This is a great addition to the
cool guitar pedals
we’ve seen here.

However, from the guitar player’s perspective, it’s really just an “oh cool” pedal that doesn’t have much use at all in performance. A looping pedal without Overdub is useless in live situations for getting any kind of a rhythm section going. It’s really only useful for the pitch effects, as demoed in the video. I see no reason why any guitar player would ever use the burst mode, because you can’t get any kind of feedback as to when the pedal stops recording. You may want to play around with some of the low-end looping pedals out there, like the Boss RC-2 or digitech JamMan, and observe how overdubbing works. I personally wouldn’t look at a looping pedal twice if it couldn’t overdub, but I understand that this was more of a proof of concept and a fun project, and in that sense you succeeded. So again, good work, I’m not trying to discourage, just providing feedback.",

Hackaday alum [Will O’Brien] has been doing
some cellphone integration work
. He recently picked up some Motorola c168i cellphones from eBay. It turns out there is a serial port that uses TTL communication with a standard head-phone jack as an interface. [Will] soldered up a connector and used a USB to
FTDI
cable to interface with the phone. To his surprise he was able to read off the stored text messages even though they were PIN protected in the phone’s operating system. The messages on these units were trivial but this is another example of the importance of clearing your data before discarding your devices.

DIY Aluminum Heat Sink Casting

[Peter Wirasnik] has been
casting his own aluminum heat sinks
. He’s working on capturing the heat from a car’s exhaust system and turning it into electricity, kind of
like the candle generator
. In the photo above a standard heat sink is bolted to one side of a Peltier cooler with [Peter’s] own casting on the bottom. That casting will connect to the exhaust pipe and transfer heat to the Peltier while the other heat sink keeps the opposite side relatively cool. What results is a voltage between 600mV and 1V.
We’re not quite sure what the end product will be but
the casting process
is fascinating. He carves the shape of the piece he wants to cast from Styrofoam and embeds it in a box of sand. He then melts salvaged aluminum in a cast iron frying pan using what looks like a propane torch. Once molten, he pours the aluminum into the mold and it burns away the Styrofoam as it fills the void. A little cleanup and he’s got the heat conductive mounting bracket he was after.

Worked in an aluminum/magnesium plant for 2 years. fyi for all the tards out there, NEVER mix hot molten metal with water. Even if you’re cooling down the casting. A large hunk of aluminum like that could stay gelatinous in the center for up to 10mins at least. I’ve saw 10 pound slugs of explode and almost kill a man because a water line broke open on it. if water is trapped in molten aluminum it can expand into steam to be at least 10x the original size, and magnesium can instantly explode and flash back at you.

Green sand is fine sand mixed with either water or oil bound clay to hold its shape and give smoother castings.Also depending on the source of the aluminum there could be mass impurities. It’s really best to cast from ingots rather than directly from scrap.It takes 20-32 aluminum cans to make one pound of metal, excluding losses to dross. 20 if they’re all from beer cans, 32 if its from lighter weight soda cans. If you’re going to cast from light gauge scrap it’s best to get a pool of metal going and add the scrap to that to limit the exposure to oxygen, otherwise you’ll get mad amounts of dross.And as others have said you can make a charcoal foundary for well under $10 if you already have a leaf blower or other high volume air source. Propane ones aren’t that much more expensive if you build your own burners.Also unless he laps the exhaust mounting block the heat transfer is going to be abyssmal.Check outhttp://www.backyardmetalcasting.com/for some indepth discussion and lots of pictures.",

"content": "I tried this years ago. This is not an easy project and will require a heck of a lot more than installation of a heat recovery system. You need to greatly reduce the electrical consumption of your vehicle to make this worthwhile. LED conversion for all lights would be the easiest. There have been a number of studies and a ton of research in industry has gone into this exact application for peltier devices. I feel that this is worthwhile however the physics are a bit disheartening. The surface area in terms of consumer-grade peltier elements that is required to drive a typical car is impressive to say the least. After I had already bought a whole slew of peltier elements I ran the numbers. If memory serves the area required was measured in square meters. Not reassuring.Now, for all the braindead morons who are shitting on this guy saying that this has no application; an automotive alternator consumes a massive amount of energy. 10 – 15% on a typical car. …more if it’s a small, efficient car. The engine will rev much more freely and your vehicle will consume less fuel if the alternator is eliminated. Today manufacturers are scrambling for fuel savings that amount to less than 1 mpg. Elimination of the alternator amounts to much more than this. There is huge incentive to eliminate the alternator entirely.Volts do not equal power. 1 volt could provide enough power to run a city if you had a lot of amps behind it. Practically yes, this might be difficult to accomplish however theoretically it’s possible. I don’t see why you guys are bitching about how 1 volt is not significant. I mean, James called you guys out on the series connection thing earlier but he shouldn’t have had to. That is amazingly basic electrical theory.Magnets on any rotating equipment is simply creating a generator. That is not free energy. A joule of energy will cost you at least as much in gasoline as a joule from the alternator.First of all, the exhaust absolutely cannot sustain a peltier element. It’s a hateful environment and although it seems good at first you won’t be able to get it to work. Scavenging waste heat from the cooling system is much, much better. Your peltiers will live a much longer, happier life and will thank you for it. You should be able to achieve at least an 80C temperature differential across the peltier, which is much healthier.Funny enough, cooling the exhaust is actually a bad thing, even on a naturally aspirated engine.As for my experiment it ended in complete failure. I got my ass handed to me by the laws of physics. Oh well. My alternator still ended up being a fixture on the garage floor. My car’s electrical system is now solar powered. It works well and has been for nearly 2 years.",

"content": "If you want to increase fuel efficiency, turn your car into a plug-in hybrid (of sorts) simply by installing a switch in series with your alternator field windings. Use the switch to deactivate the alternator (with no current through the field windings the alternator will just spin freely without drawing or producing power). Use a dash mounted voltmeter to monitor battery voltage.I made the above mods to my car in a couple hours. I drive with the alternator inactive most of the time except for long trips that would drain the battery completely. Most of my trips are short and don’t come close to draining the battery, so I can charge the battery at home instead. I have a 4A smart charger permanently connected to the battery and mounted in the engine compartment. A 3 prong electrical plug hangs out the grill and looks just like a block heater plug. I just plug it in when I park. When I’m leaving, have it set up so I don’t even have to unplug it. I just back away and it unplugs itself.In my small Chevy Sprint, electrical power accounts for around 10% of fuel consumption, so this method gets me about 10% better fuel economy just by producing my electricity from a source other than gasoline. Yes, the electricity to charge the battery still costs money and may be produced by burning coal, but if you run the numbers, both your cost and your carbon footprint are actually significantly reduced.The energy density of gasoline is about 9 kWh/L. A litre of gasoline costs about $1.40 where I live, or about $0.16/kWh. Divide by typical engine/alternator efficiency of 10% and I pay about $1.60/kWh for alternator produced electricity vs only $0.08/kWh for electricity from my home. Even allowing 50% battery losses charging from home is still 10 times cheaper than using gasoline to produce the same electricity.Mods like those above above are MUCH simpler and MUCH more effective than converting exhaust heat to electricity. The above mods will actually pay back on parts, labour, and carbon footprint in under a yearGranted, casting stuff is fun, but saving actual $$$ at the pump from mods you did yourself is more fun in my books. With this and other simple mods, I average about 60 MPG in the city (up to around 70 MPG in the summer and down to 50 MPG in the winter) and sit comfortably in the Top 10 at gassavers.org, (except in the winter when southerners have a significant advantage).It’s not rocket science. It’s just high school physics. Anyone can do it, and no self respecting hacker with a car has any excuse not to. Figure out what 10% of your annual fuel bill is and see if it’s worth a couple hours of your time to eliminate it.PS. For an extra 5-10%, consider running your water pump from an electric motor controlled via thermostat to match engine need rather than running continuously like a typical belt driven mechanical water pump.",

Submarine builds are always fun but frequently produce headaches when it comes to keeping the water out. [Jason Rollette]
built this ROV to explore a shipwreck in Lake Michigan
. The main structure is PVC and various bilge pumps are used for propulsion. An AVR ATmega32 controls the on board electronics with an Ethernet tether to the surface. He’s even got a visual basic program that displays system information and a video feed. It may not be as stylish as
the last submarine we saw
but it’s amazingly well thought out and well built.

Low budget projects can use oil (it floats and doesn’t compress much.), preferably vegetable based if you want to spare severe fines for any leaks. For oil you will need pressure compensation between the vssel and the sea, think rubber bladder like say is used for hot water bottle or pneumatic lifters for cars. As to wire? Many companies sell Teflon or silicon jacketed cable specifically made for sub-sea use. Cheaper alternatives are any wire rated SO, SOO, or SOOW. For splices and general waterproofing nothing beats Scothcast 2130 or 2135. Motors and electronics can be filled with oil and compensated, Cameras not so much. Cameras need to be mounted in aluminum or steel housings (think pipe.) For connectors and pass throughs hydraulic fitting + Scotchcast.

Is That Some Type Of New Kindle?

"ebook",
"python",
"reader"
] |
[Mr C Camacho] picked up an inexpensive digital picture frame hoping to hack into it. He hasn’t had the time to crack open the hardware so that it will do his bidding but he did find a creative way to make it an ebook reader. Using a python script he processes books, creating images of the pages.
The python script, available after the break, takes free books from
Project Gutenburg
and spits out JPG images. Page turning and bookmarking are not what they ought to be but the process does work. The thought of someone staring at a picture frame on the subway is a bit amusing but we’re sure that sooner or later someone will ask if it’s a new version of
the Kindle
.
Usage explanation from the developer:
./process.py book.txt 480 234 16 /usr/share/fonts/truetype/ttf-droid/DroidSansMono.ttf 10 7
param
1 book.txt the file name
2 480 native X resolution of picture frame
3 234 native Y resolution of picture frame
4 16 Number of vertical lines of text required
5 blah.ttf full path and name of a ttf font
6 10 font size to use for lines
7 7 font size for “page no x” at bottom of page
you’ll have to play with it to get it to work right for your size of screen
(its just a hack ;) )
The main thing to get right first is the font size of the width of the screen
from there you can work out the number of lines you can fit…
#!/usr/bin/python
import pygameimport sys
# ./process.py book.txt 480 234 16 /usr/share/fonts/truetype/ttf-droid/DroidSansMono.ttf 10 7
txtname=sys.argv[1]nativeX=int(sys.argv[2])nativeY=int(sys.argv[3])pagelines=int(sys.argv[4])fontname=sys.argv[5]fontsize=int(sys.argv[6])pagenosize=int(sys.argv[7])
f=open(txtname)
def cleanline(l): l=l.strip('\r') l=l.strip('\n') return l
pygame.init()screen = pygame.display.set_mode((nativeX, nativeY))lines=f.readlines()font = pygame.font.Font(fontname, fontsize)pfont = pygame.font.Font(fontname, pagenosize)
for ln in range(len(lines)/pagelines+1): background = pygame.Surface(screen.get_size()) background = background.convert() background.fill((255, 255, 255))
for pl in range(16): if (ln*16+pl)<len(lines): line=cleanline(lines[ln*pagelines+pl]) text = font.render(line, 1, (0, 0, 0)) textpos = text.get_rect(x=4,y=pl*(nativeY/pagelines)) background.blit(text, textpos) text=pfont.render("Page "+str(ln+1),1,(0,0,0)) textpos=text.get_rect(x=8,y=nativeY-pagenosize) background.blit(text,textpos) screen.blit(background, (0, 0)) pygame.display.flip() fn="page%#05d" % (ln+1) pygame.image.save(background,fn+".jpg")

Where is the Rockbox of the picture frames?Is it because there is no one platform that is common enough to justify the work or because the processors/chips are non-standard or because the design of these things tends to be so one off and closed that there isn’t an easy opening to flash in a replacement firmware?Not that I’m saying reversing a device firmware is easy or anything.

Gentle Wake Up Alarm
|
Caleb Kraft

[
"clock hacks"
] |
[
"alarm"
] |
[Michiel], unsatisfied by his Phillips wake up light, decided just to
make his own
. He really wanted programmable weekend alarms as well as an easier to find snooze button. At first, his circuit was not reliable enough, losing several minutes per hour, but he gutted another alarm for the 1Hz crystal. After some carpentry, his final alarm ended up quite nice. After so
many
aggressive
alarm clocks
, it’s nice to see that not everyone needs to be assaulted out of bed.
Correction: apparently, there’s no 1Hz crystal. That was a guess on my part. -[Caleb]

Calculating 1.661mm/0.000001, you would need a crystal 1.66100 kilometers thick.Now, can anyone calculate how much POWER you’d need to oscillate that crystal?",

The whole thing (along with the other house lights) is just controlled with cron and some simple perl scripts.A bonus is that you can’t snooze it (if you turn the light off, it will come back on when the next SET DIM comes in in about 30 seconds) so I have to get up.I also have it dim the lights down when it’s time for bed on work nights.The only thing missing is there isn’t quite enough blue spectrum to wake me up completely, like the sun does. I’ve thought of mixing in some of those horrible CFLs but you can’t dim them – and I hate the light",

You can generally use the internal timer/counter hardware to count clock cycles and derive your timebase from that. For example if you have a 10MHz crystal, you can set up a /8 prescaler to get 1.25MHz in the counter. Use an 8-bit counter set to fire an interrupt and reset at 124 and you’ve got yourself a 10KHz interrupt.Another approach for your sort of timing application is to let the counter free-run but interrupt on overflow. Use the overflow to maintain a software counter, and stop the counter based on your external timing interrupt. The software counter are your MSB and the timer value the LSB.You should use a TCXO or OCXO for any kind of timing application.",

If you are anything like us, you find yourself needing, on occasion, to fling sausages at high velocity. [F00] sent in his solution,
the SG19
. While the details are glazed over pretty quickly, we get the point. This is basically a smaller diameter
spud gun
, meant to shoot sausage. While it may not be remarkable in its design, we have to wonder who came up with the idea to use sausage as the ammunition.

This video
was on its way to a
links post
until we saw the game of chess right in the middle of it (bishop to H5).
[Tom] and [Ben]
put their Master of Manufacturing Engineering degrees to use by jam-packing every conveyance method possible into a
Rube Goldberg machine
. There’s violin bows, a polo mallet, a rolling candle, a ball-popping umbrella, texting cell phones, toppling jewel cases, and plenty of
ball-on-tracks
implementations. All of that setup and all that the device does is… well, you’ll have to see for yourself.

High Speed Video From Cheap Digital Camera

"high speed video",
"micromirror"
] |
Some researchers from Oxford University have come up with a way to produce high-speed video from a one mega-pixel camera. They’re calling the method
Temporal Pixel Multiplexing
. This method adds a
digital micromirror device
in line with the camera lens. These chips house over a million mirrors and can be found in home theater projectors. By placing one in front of the digital camera, a longer exposure can be used while the DMD redirects the light. This way, one high-resolution image actually contains multiple frames of lower-resolution video. The video is still decent quality and, at a far lower cost than common high-speed video equipment, this is a worthwhile trade off.

"content": "@kirovYou are right of course, you don’t get something for nothing.The way this works is to capture the image four successive times, on four different sets of pixels that are evenly mixed and spread out across the sensor area. Micro mirrors are used to the light to these pixels.After the 4 images are taken the whole ccd will have been exposed, hence the full resolution image. Also you will have 4 distinct time periods when different images were captured, although with 1/4 of the resolution for each frame.So far so good, the catch is of course the 4 time periods which make up a single image must be fast if you wish to avoid image blur etc. This means that only a small quantity of light will reach each pixel (1/4 of usual) so the sensor must be much more sensitive, and therefore expensive (or await newer tech…)This is obviously an interesting idea but my cell camera is crap enough without restricting the light even more…",

"content": "This is a bulky, roundabout way to achieve an identical result to what high speed cameras already do. They put multiple images on the same frame, meaning that when the data is read out from the sensor, you have a lot of reduced-resolution images for a much higher framerate, and the same data bandwidth. However, that’s what most high speed cameras already do. Since image sensors are basically giant arrays of shift registers, the most time is spent shifting out all that data, not actually capturing the light. If you only read a smaller portion of the sensor, then you can do it many more times per second. The output is the same as the above approach, but doesn’t require any micromirror devices.",

Do you ever wonder what projects your neighbors have going on in their basements? [Will Jack’s] neighbors might be surprised to find
he’s building a fusion reactor
. The first step toward completing a
Farsworth-Hirsch Fusor
is up and running. The picture above shows heated plasma contained in a magnetic field. Next he just needs to up the voltage and inject some deuterium.
Yeah right!
Deuterium
, aka heavy water, is extremely rare and very difficult to refine. If you’re not familiar with the substance, you should get your hands on the NOVA episode:
Hitler’s Sunken Secrets
.
We’re glad to see that [Will Jack] is donning a lead vest for protections. [
Will O’Brien
] cautioned us about the stray X-rays these things produce when
he covered fusors back in 2007

This is a pretty difficult task as the vacuum has to be strong, but its possible. if he gets arcing between the charge grids, he can also risk making some nasty x-rays, so good call with the lead vest.

This is a project that requires a good working knowledge of high voltage, and that’s its primary danger. In terms of neutron flux, it’s really really hard to get to dangerous levels with this. Higher voltage, really good vacuum in a metal jar, and a few refinements are usually necessary before getting more than a few neutrons. Worst case scenario, assuming he gets thousands of times more neutron flux than the average amateur built fusor, you set a bucket filled with water and borax next to it, and mark the neutron shadow of the bucket with duct tape on the floor so you know where the safe area is. You’ll get some neutron activation in certain materials, but that falls off with the cube of the distance so its pretty limited to the jar and the electrodes.K",

Update: Most Interesting Game In 64 Pixels

[Brad] has
continued working on the Super Pixel Bros game
. We saw
a glimpse of this
a few months ago but he’s added a lot since then. The game now has enemies; one type is similar to
Bullet Bill
, another type drops from the sky and walks toward you, kind of like a
Goomba
. Game play is quite responsive and it’s amazing what he has accomplished with such low resolution. In the video after the break [Brad] mentions that a friend is working on sound effects for jumps and block breaking. We’re assuming that the audio track in the background is already coming from the LEDBOY speaker.
Which reminds us, if you haven’t
checked out the hardware
, do so now. That enameled wire mess makes us shudder just a bit. There many be a kit version coming that will save you the point-to-point soldering madness. If that’s part of the fun for you keep an eye out for the forthcoming release of the hardware schematics.

"content": "Hi everyone, thanks for all the comments.Just to clarify a few things. I am a busy Dad now that we have two kids so I don’t have a huge amount of time to devote to these projects, but I add what I can when I do get a bit of free time.This game is programmed in assembly language (and some might say poorly at that…) on a pic18f4550 microcontroller. This game has been quite a learning experience for me and as such the code is not very efficient, but it seems to work okay (excpet for that bad guy that falls from the ceiling and doesnt move properly…I originally had it so that you would not go back to the start of the level, but I wanted to make the game a little more challenging, so I changed it.The gameboy wasn’t broken – but I have about a dozen more, I collect retro video games / consoles. and yes, it was more useful when it was in the gameboy, but i’ve had fun with it = )And as for the kit form – a couple of years ago I came up with the 8×8 game system which used an RG LED matrix and had games like pong, car race, adventure, painter and space invaders on it. I sold it as a kit for $20. So basically you would get all the parts and PCB and then solder it together yourself. Then you would upload a game and hopefully learn a little about programming in the process.I sold quite a few of those so I thought I’d see if people were interested in the one as a kit also.I will upload parts list, schematic and source code to my site as soon as I can get the time to sit down and get it all documented. In a nutshell you would need:8x pushbuttons1x 8×8 RGB LED matrix (common cathode)4x 743731x pic 18f45508x NPN transistor (2n2222a is good)16x 10k ohm resistor24x approx 100 – 150 ohm resistor1x 7805 regulator (if supply voltage exceeds 5v)a sprinkling of capacitors for good measure.",

These boxes, called
Flexi Knobs
, work like a wireless Atari paddle and mouse rolled into one. Each has a rotary encoder that can also be clicked like a button. On the inside is a wireless optical mouse which controls an on-screen cursor which matches the color of the knob. In the video after the break you can see these are being used as midi controls. Each cursor can be locked onto a virtual knob, giving it a physical interface. Because there are several units being used on one machine this creates something of an abstract multi-touch system. This would make a nice interface for other applications with a plethora of settings, like
Blender
.

(toolbar was specifically written to take advantage of being able to move around, such as click-through events that will target the window and the canvas in that sequence, one click Fill was an example)Simple things like this can go a very long way in saving time.Wish i knew more about it, but i lost it when my old laptop died.",

[thetanktheory]
sent us his glove mouse modification
. He has gutted his mouse and mounted the parts on a glove. This is interesting, as he doesn’t have to place his hand on the mouse any more, he just plops it down on any surface and starts mousing. He claims that it is helping his twitch reactions in gaming as somehow it requires less force, but we still see the circuit and batteries mounted on the back of his hand, so we’re not sure how it is helping. Maybe if he moved the laser to his finger tips, he’d be more accurate.

[Andrew] built
this pong clock
over the span of a couple of days. The PIC 18f2520 he used can serve as a real time clock with the addition of an external clock crystal. His project proves the usefulness of an oscilloscope as poor board layout caused interference in the crystal connections, something difficult to troubleshoot without this handy lab tool.
Pong clocks
have been
quite popular
. This one is nice because it’s easy to throw together now that [Andrew’s] done the coding work for you. Written in assembly, reading and understanding his code might be a good exercise if your low-level language skills are lacking.

Tired of fighting Windows mobile on your HTC handset? Now you can fight a beta ROM of Android 2.1. [Slm4996] has put in a flurry of work over the last few days to
get Android 2.1 running on the HTC Kaiser (aka AT&T tilt), Vogue, Niki, and Polaris
. Right now everything except the camera and bluetooth is working but there is a
bug tracker
to help with troubleshooting any undiscovered issues. If you want to try it out but don’t want to flash the hacked ROM to your phone you can run it beside Windows Mobile by using
HaRET
.
Correction:
The title of this post originally read “Droid 2.1” in error. We have corrected it to read “Android 2.1”. [Thanks GuyFrom7Up]

Robocup Bot Places Wheels Perpendicularly

"omnidirectional",
"robocup",
"soccer",

"wheel"
] |
[Eric]
built this robot for the 2009 Robocup Jr. competition
. The game ball has IR LEDs inside of it and this little bot uses eight IR detectors for tracking. Four motors mounted perpendicular to each other provide locomotion. Since this would normally have you traveling in circles, he used some omnidirectional wheels walled
Transwheels
. As you can see, they have small rollers built-in and allow movement in any direction if the motors work together. A couple of L298 controller chips handle the motors. [Eric] wrote a program to calculate the PWM necessary to drive the controllers and to coordinate movement of the wheels.
Don’t miss the demo videos after the break and, if you’re not a fan of wheels, stop by and see
the bi-pedal soccer robots
.

Powerplant control room panoramas:
There are two power plants presented in
360 degree panoramas here
. All those dials and switches just get us giddy. The one pictured above was built in 1918 and is still in operation. Not only are the control rooms here, but several other locations around the facility too.
Energy recycling prosthetic foot
:
At first, we thought that this
energy recycling prosthetic foot
was going to be a power generating device to harvest some energy using our weight in the heel compression. Actually, it is showing off a fancy micro controller based system for reproducing our naturally springy step.
Translating in real time with google:
Google is working on a system to do
real time translation of text on your phone
. It is integrated into the “google goggles” software which allows you to search the internet using images from your phone. This is pretty cool, but with google translate and OCR being readily available for quite some time now, we have to wonder; why didn’t we think of that?
Exploded images of everyday objects:
[Adam Voorhes] has put together a small collection of
exploded views of everyday objects
. While they aren’t laid out great for reference, they look good and might make nice artwork in your workshop.

[Sprite_tm] brings us another great hack by
lighting up the living room
. Unsatisfied with just
replacing incandescent bulbs with an LED alternative
he went with strips of LEDs to illuminate the length of a wall. Starting with a seven-meter strip of the lights, he cut it down to fourteen pieces in order to make the RGB devices individually controllable. [Sprite_tm] whipped up a design for controller boards using RS-485 to communicate with each, and sourcing an ATtiny2313 for the PWM necessary to generate any color. As you can see in the video above, the finished project is brilliant. Oh, and the Lounge Music as a background is nice too.

I built one before using my own driver PCB, but the inductors on it squeal, and I’ve since managed to kill the microcontroller (static?)I had it take RGBW values in ascii hex, so I could echo them to my serial port, or stream it values through software.I can get serial at pretty high speeds off of those adaptors, so it would be fairly easy to sync the light from an external source.

Should be a useful little board as a cheap USB->I2C device too (though i2c-tiny-usb already does this).My plan and goal *is* to do an ambilight clone, but I’m also kinda hoping it’ll be flexible enough to solve many computer+LED problems. Lots of ways already to do the ambilight stuff though, there are a few implementations out there already to look at. I’m pretty sure there’s one at the boblight guy’s blog somewhere, and when I was researching this project I found a couple others as well. Plain RS-232 at 57600 seems fast enough for convincing ambilight, and I’ve already got this working pretty easily with an AVR (though with the bitch-to-use TLC5940), not a hard project at all if you’re using an I2C chip, probably well under 200 lines of code.",

It’d be nice to have a lead on an easier to modify design.Also another thought: If you built a usb-tiny-i2c and just hooked it directly to one of the I2C chips you could do basic control just with i2c-tools and bash. A bit more work with libi2c or writing a kernel driver and you could do it with virtually no hardware or firmware development at all. Though usb-tiny-i2c is pretty slow it’s probably fast enough.",

I used .47uF because I had them handy.the TX is pin 1, so it’s easy to air-wire, and the RX is available at the top of the 5th unpopulated SMT connection from the left in the row of 12 in the little white boxes at the bottom edge(viewed with the USB at the right).To give me something solid to anchor to, I removed the 9 pin connector, and cut the traces to isolate 4 of the pads. then I can solder my wires to there, so I’m not accidentally ripping pads or pins off when I connect the module to other stuff.I steal 5V for the microcontroller from the USB pins as well.The chip is rated for 6Mbps, but since I’m clocking the micro from an 18.432MHz crystal, I stuck to a semi-standard 460800bps. (~0% error)I don’t think the crystal is really necessary.

Steorn Orbo Motor Replica

Reader [Hjhndr] ran across an interesting set of tests and wanted to know if they’re brilliant or just a load of bull. We’re not making the call on that, but the
tests on a Steorn Orb motor replica
are worth looking at.Keep in mind, people used to think the earth was flat and scientists of the time would have sworn up and down that’s the way things were.
The
Steorn Orbo
is a motor that generates more power than is put into it. At least according to
Steorn Limited
that’s what it does. An independent panel of scientists said otherwise a few years back but that didn’t stop the company from showing off the concept a few more times, most recently a showing in Dublin ended this month.
So anyway, [Jean-Louis Naudin] took what he saw from those demonstrations and built a replica. He’s made several papers about
the principle
as well as his testing available online. There’s a lot of math, a little bit of smoke and mirrors, and several videos. Take a look and let us know what you think in the comments.

The lie is that you can negate the force of attraction without doing work. Changing the direction of the ferrite’s magnetic domains in the presence of a magnetic field requires work – at least as much work as is recovered “freely” as the motor spins to the next position.",

"content": "It doesn’t work because in order to release the magnet the coil has to generate a force and do work on the magnet against the pull of the permanent magnets. Importantly, this extra work is only done _if the coil is released_, since work done is force times distance. This work presents itself as an e.m.f generated in the coil opposing the current traveling through it, due to lenz’s law.His last demonstration experiment is therefore invalid because he only tests it with the magnet present or not present, not with the magnet being released from the coil.Also note that in any case where he demonstrates supposed ‘free energy’ he measures only current, not voltage, which is where the extra power draw would manifest itself in this case.This can happen because, if he is driving the coils in the motor in the same way as his demonstration model, he is creating a current source, which adjusts its voltage output to keep the current running through it constant, instead of the normal situation where voltage is constant, and current varies.This, in fact, accounts for all the effects he notes in his experiments, although is also depends on where he is measuring the voltages he quotes on his graphs, which he doesn’t mention. If they are, as I suspect, the voltage across the power rails to his driving circuit, then the ‘free energy’ he is noting is simply being diverted from the MOSFET, which would dissipate less heat as the load on the motor increased.",

When not powered, the permanent magnet attracts to the ferrite core. To push away the permanent magnet, he applies an electrical current to the coil.Then he writes: “Don’t forget that the free mechanical power produced by the magnetic attraction of the magnets towards the ferromagnetic core has no link with the electrical power spent to release the magnets.”… correct me if I’m wrong, but to mechanically repel or “release” the permanent magnet from the ferrite core, you have to put electrical work into the coil to counteract the EMF inducted by the magnet. At best you can perfectly cancel the EMF, but this does not create motion. In fact, it just keeps the magnets in place at a sweet spot, where the magnet’s attraction and the opposing field balance out (kinda like the way superconductors keep magnets repelled at a certain distance). To ensure that magnets are completely physically repelled, you have to put in more power.",

[Nicholas] built
an active tracking system using RFID tags
. The system’s tags operate in the 2.4 GHz band and are used to track either people or assets. The readers are on a mesh network and can triangulate the location of any tag for display on a map. His system is even set up to show the travel history of each tag. [Nicholas] shared every detail in his writeup including some background about available hardware options and how he made his final decisions on what devices to use for the job. His conglomeration of software that ties the whole project together is also available for download.

Details here:http://www.cl.cam.ac.uk/research/dtg/attarchive/location/They got round the privacy/employee hostility problem by making the badges completely voluntary. The tags made the employees lives easier: Doors opened as you approached, you computer desktop appeared on whichever computer you turned to, your phone calls came to the nearest phone. Most useful – you could ask the server where someone was and get told which room they were in – saving countless man hours of walking around looking for them.But under all of this was the view that it should be voluntary – if you wanted to leave your tag on your desk while you got a coffee/smoke/etc, that was fine. And enough people did just that to ensure that while the data was mostly useful to the employees, it couldn’t be used by management to *prove* anything.So with management understanding and buy-in, there are ways to make this privacy trade-off work and find a happy medium.",

Cannihilator Can Crusher

"bs2",
"can crusher",
"solenoid"
] |
This box will
crush your cans and deposit them in the bin
below. Branded the Cannihilator, [Jeff Walsh] built this with his two sons, [Jake] and [Ryan]. Early hacking eduction is important if they want their future projects to be regular Hackaday features.
The crushing power is provided by a
solenoid
pneumatic ram. As seen in the video after the break, the can goes in the door on the left, is crushed, then drops through a slot. [Jeff] had fingers and hands in mind when designing this and included a few safety features. The “crush” button is locate on the opposite end from the can slot, there is a kill switch to disable the solenoid, and a keyed switch to shut the whole apparatus down. A Basic Stamp 2 microcontroller handles the electronics with the help of a daughter-board to manage the load switching. This is a nice addition to the
creative can crushers
out there.

I don’t trust fail safes that rely on the proper functioning of software in order to work. The interlock should open dry contacts independent of whatever your processor is doing.",

Sukhoi Su-27 Jet Build Throws Down

"su-27"

This no model, but
a fully functioning RC jet
. The
Sukhoi Su-27
was the Soviet Union’s counterpart of the F15 and this 1/6.5 scaled version measures eleven feet long and is fully controllable. As if
the 80-page build log
wasn’t enough, the flight video after the break is nothing short of jaw-dropping. The test flights end in smooth landings but with all the time that went into the project that’s got to be nerve-wracking.

It’s this plane and developments to it that very much spurred on the development of the F22 Raptor as far as an air-superiority fighter was concerned.That being said, this guy’s build is flat out AWESOME.

The folks over at NerdKits got a shiny new Smithy 1220xl lathe/ mill. They found, however that adjusting the Z axis wasn’t as accurate as they desired. They decided to
resolve this by installing a digital caliper and an LCD interface
to display the adjustments. The writeup is quite detailed and the results seem to work great.

One of the machinists I learned from called calipers (vernier, digital, whatever) ‘guessing sticks’. Personally I’ve found my cheap ass dial caliper from princess auto works pretty well to within .005″ or so but if I need to be more precise I pull out a micrometer. A quickie solution to this problem (you get it a lot with old equipment where the dials are no longer reliable) is to use a simple dial indicator, and that should let you get accuracy within .001″.",

"content": "Hi @urlax — thanks for the feedback!You’re right that without a pull-up resistor, the microcontroller pin is momentarily left “floating”. However, the input pin capacitance will essentially maintain the previous state. Although, if there is significant switching noise radiated from a nearby circuit (perhaps a nearby unterminated digital line with fast edges), it might capacitively couple onto that floating pin and cause it to change state. This is much more likely to happen when there’s no pull-up (purely floating), but at some extremes of high nearby switching noise and a high enough resistance value to the pull-up resistor, it might be possible to have that coupling happen even in the pull-up case.But most importantly, with a pull-up resistor or not, there’s always a transition through the middle, and you need to deal with the inherent “junk” during the transition, period. Debouncing the switch, or alternatively having a UI that simply doesn’t care if there are multiple button presses (like we have here — zeroing it a couple times within a few milliseconds doesn’t make a darn difference), will be necessary with or without a pull-up resistor. With a pull-up resistor + SPST switch, the “junk” comes from the physical movement of the switch contacts, and with a SPDT switch without a pull-up resistor, there may be some extra “junk” (noise capacitively coupled onto a floating pin) within the “junk” of the physical switch contact transition — does that make sense?I would say that a pull-up resistor might also be useful in a case where a switch could physically become disconnected and you establish a default state — imagine a “fire zee missiles” button, where if the switch somehow gets disconnected, it’d be best if the input pin were kept in a particular “DON’T fire zee missiles” state. :-)In the end, we all agree that a pull-up resistor is the best solution for a number of reasons.Hope that helps!(FYI, I’m the guy in the video.)",

That way you get several times the noise immunity.I once had to do that while making a converter for a metric linear scale to use it on an inch machine. The data was garbage until I switched to having my PIC receive both A and A-bar, B and B-bar. Then there were no glitch problems evermore.The failure mode: An external electrical noise source couples in to both the Clock and Data signals. If it’s a positive-going noise pulse, it will have no effect on a 1, but will briefly make a 0 look like a 1. Conversely, if it’s negative-going, it can temporarily make a 1 look like a 0.Now if you’ve got both the A and A-bar version of the signal to look at, only one of them can be corrupted, and that’s not enough to make the output change state. Viola: noise immunity.Hope that helps someone.",

This
hoodie senses your heartbeat and uses it to control Life
. Conway’s Game of Life, popular in
all kinds of electronics projects
, uses a grid of cells coupled with
a set of rules
to mimic the life and death of simple organisms. This iteration displays the game over your own heart, then taps into your heart rate, resetting the game at the beginning of each cardiac cycle. We guess you could say that Life goes on only if you do not.
The
EKG circuit
that detects the heartbeat is made up of an IR transmitter shining through the tip of your finger to a receiver. An ATmega168 running the Arduino bootloader controls the EKG circuit and resets an ATmega48 which is responsible for Life. [Joe] admits that this is overkill but he’s currently without an AVR programmer; he went this route to make it work. The stylishly-geeky hoodie is taken for a test run (er… test-hop?) after the break.

What i was referring to was the technology (using IR) to detect heartbeats (which IS really dirty and unscientific) – I was NOT referring to the circuit itself. The circuit is fantastic, worked great, and as you said, VERY CHEAP. Your schematic was very clear, and I DID link to it – but, I will add your name in my post as well (unless you don’t want me to… email me if that’s the case). Thanks very much for posting your great work–",

Hub motors
put the power inside of the wheel. [Teamtestbot] goes deep into the hows and whys of building these motors, from parts, to windings, to the math behind the power ratios. The working example puts an electric motor inside the rear wheel of a Razor scooter.
Past projects used belts
to transfer the work of the motor to the wheel of the scooter. By integrating the motor and the wheel you end up with a much cleaner looking product. Check out the motor testing and the scooter test drive after the break.
For more tips on building your own electric motors take a peek at the
Fly Electric page
we covered back in November.

show us his Eeepc that has been modded with almost every upgrade
you can cram in one. He has an external cantenna for his wifi, an iPod hard drive, touch screen, added bluetooth with indicator lights, and an internal USB drive for booting linux. While the details are somewhat lacking on his site, you can find an article here for every piece you need to recreate his work. We’ve covered
adding the touch screen

mounting external antennas
,
doing it all without solder

changing the form factor

Buy stock in hot glue, this project corners the market on the stuff. [Leafcutter John] uses the hot goop as his water-proofer of choice when
building an underwater microphone
(also known as a hydrophone). By installing a couple of piezo elements on one lid of a tin can he is able to record some amazingly clear audio. This is aided by a pre-amp inside the metal enclosure. By cleaning off the clear coating from the inside of these steel can parts, he was able to solder the seams to keep the water out. In the end, coins are added for ballast and any remaining space is completely filled with hot glue.
He’s got a handful of example recordings on his project page. Here’s an what a running faucet sounds like from under water:

The cable coming out of the tin can then be as long as needed (see what i did there)As for hot glue, i think it works well for this purpose, and it wont burn you unless you get a sizable blob on you, then it f*&%^n hurts as macegr will attest. I agree with Scott that a harder material may be better for the sound.The water sample does sound tinny, I actually stuck my head in the sink and listened to that sound.

What sounds like a sex-toy is actually the reason these musicians haven’t been practicing. Marv is the
MIDI actuated robotic vibraphone
built by [Tim O’Keefe], [Michael McIntyre], and [Brock Roland]. Every key has a solenoid positioned below it. The beauty here is that other than four small holes used for mounting, the vibraphone hasn’t been altered at all. The solenoids are positioned on the outside edges of the instrument but there’s also a hidden secret. A set of dampers have been installed between the two ranks of keys. These are used to stop dampen ringing keys after the note should have stopped.
These guys have exhibited some beautiful craftsmanship. Check out the videos after the break and if you have the chance, see Marv in person at
BarBot 2010
. If you do attend that robot extravaganza don’t miss your chance to enjoy
a breast-pump actuated cocktail

They just replaced that with a system of individual dampers since a human can also use the mallets to soften dampen keys as needed.As for the sound, I’m thinking the reason it sounds harsher than normal is because, at least it looks like, the keys are being hit by solid plastic/rubber. Vibraphone mallets are generally have a rubber core, but are then wrapped in several layers of yarn to soften the blow, resulting in a less harsh sound. I know from experience that if you strike a vibraphone key with just a rubber mallet, it produces a sound closer to that in the video.",

This track is awful, someone skip it!
This project
does just that with a wave of your hand. A laser beam shines across a room and, when obstructed, it sends a command to an iPod. One wave pauses playback, two waves skips to the next track, and a constant obstruction jumps backward one track.
They’re using a textile-compatible electronics platform called
Schemer
. This is the first time we’ve run across this product which uses a modular system to connect devices via a 1-wire communications bus.
No matter what hardware you use the concept is what interests us. There’s no shortage of
iPod remote
projects to draw on as examples. This method seems a bit more fun than
banging your head for track changes
or
slapping wildly at an over-sized remote
. We’re just a bit concerned about the power consumption of the laser-pointer, perhaps an IR beam would be a more economical choice?

3 breast pumps, a Meggy jr RGB (slightly modified) and copious amounts of alcohol. This sounds like a typical weekend at HAD headquarters, but it is in fact the parts list for the
Drink Making Unit
by Evil Mad Scientist Laboratories. Created for the upcoming
Barbot 2010
event, this unit is a cocktail mixer. Load 3 liquids in, program the Meggy and you can push a button to dispense. We are pleased to see how much they modified off the shelf components to make this happen. Yes, there could be major improvements like mixing, more liquid reservoirs, and a better cooling system, but we think this thing is pretty slick.

Binary Clock Uses DS3232 RTC

[Kenneth Finnegan] quenches our clock-a-day compulsion with his
Arduino based binary timepiece
. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 real-time clock which automatically compensates for temperature to achieve very accurate time keeping. We like the super-cap circuit he added to keep the RTC running if the power is cut.
Is an Arduino overkill here? Well, the code is certainly not filling the 16k available on the ATmega168. At $4.32, the $1-2 you could save by using a lower-grade chip is not worth having to rewrite the code developed during prototyping. [Kenneth] also mentions that
these projects
usually only hang around for a few weeks before they’re re-purposed for the next endeavor.
Take a look at [Kenneth’s] superb hardware walk through in the video after the break. If you’re a fan of clean breadboarding, he’s also made a time-lapse of the circuit building process.

I’ve designed some hardware around the mega168 that uses nearly every single pin, all of the inputs to the ADC (including the two only available on the surface-mount versions), the I2C and UART interfaces, and two of the three timers. I came nowhere near using the full 16K of flash available.

I mean, if you can plug it in backwards, it generally doesn’t hurt to do so. The same cannot necessarily be said of raw electronics.Now, I have nothing against the Arduino. I’m of the opinion that it’s actually been very beneficial to the hacking community in general due to the ability for beginners to build projects far above their competency level, which gives them the confidence to learn more. But it frustrates me to see people perpetually using overkill components. It gives me the feeling that they don’t understand the underlying theory of the components they’re using. That philosophy is why I stopped subscribing to electronics magazines years ago – they were all about using large, expensive building blocks rather than actually learning how to move electrons around.But then, I like programming in assembler, so maybe it’s just me. :)",

Repairing Your TV EDID

] |
[Andreas] found that his
home theater PC would not boot one day
. Oddly, if he disconnected his HDMI cable from his TV, it would boot fine. While most of us would have dug into the PC, he realized that it was a signal from the TV that was incorrect. Luckily, LG had included a full schematic with the TV. What he was able to figure out, using a home made snooper was that the
EDID
eeproms had somehow become corrupted. Not to worry, [Andreas] slapped together a full blown I2C interface and prepared to reprogram them with the correct data. He noticed, however, that the eeproms were write protected. On a whim, he decided to write to them any way and found that it was successful. He has some theories as to why they were writable, but says that he doesn’t want to pull the TV back apart to confirm.

The shelves holding the manuals took up a entire wall, there was about 25 of them .

They still exist today onlinehttp://www.samswebsite.com/photofacts.htmlFor me now the problem with devices is not the schematic it is identifying the chips themselves. They have started doing one off chip production runs where they only mark the chips with batch numbers . Sometimes you get lucky and they have the company logo of who made the chip but sometimes even that doesn’t help. Often the service manuals will show the connections to the chip and what voltages should be present but still leave out what the internals of the actual chip are.To make it worse companies like broadcom, oh how I hate thee, are so paranoid about their designs you can’t even get datasheets unless you get a lawyer and have wads of cash to throw at them.",

We do so many things around here just because “we can”. Though this guy cites this as his reason, we somehow can’t help but wonder if he’s doing it just to troll the Arduino hating crowd. He has decided to
overclock his Arduino
by replacing the crystal and dropping it in some non conductive liquid coolant. Can you guess what sketch he’s running? That’s right, he’s blinking an LED.
Normally we would point out that we have no preference when it comes to Arduino. We simply post what is submitted. Though we are often accused of being Arduino lovers, it is simply just another tool to us. We sometimes delete obnoxious comments that get off topic, threatening, or vulgar because that’s just good house keeping. That being said, we know what to expect here. Go ahead, bash the Arduino. Get it out of your systems. Just keep it non offensive or it will be moderated.

The Arduino is certainly easier to use, but also comes at a much higher cost than the AtMega alone.The “haters” as it were simply don’t understand why the burgeoning hacker doesn’t just go with the Atmega or some other AVR in the first place…The AVR line of chips is rediculously easy to program and can be done with a serial port and a DASA cable. It wasDESIGNEDfor easy programming and easy use.That’s probably why people despise the Arduino. Because to these people the Arduino seems like a massive waste of money for next to nothing. Consider the Deumilanove at Robotshop.ca for instance, it’s over $30.00, in comparison the AtMega chip it uses retails for about $5.00 at digikey.ca.Just my 2c.",

We love arcade games. Who doesn’t? We feel that the “arcade” feeling just can’t be replicated in any other form factor than an arcade cabinet. [Moslevin] must feel the same way too.
He has built, what could possibly be the worlds smallest arcade cabinet
. Aside from a coin mechanism, it is fully functional. It is an ATMega328p running
his own custom software
. The games he has available are Tetris, Invader, and Breakout, all coded by himself as well. We’ve seen
small arcade cabinets
before, but none this small.

Adding Words To Catch Phrase
|
Mike Szczys

[
"Toy Hacks"
] |
[
"catch phrase",
"game",
"sd",
"usb",
"word list"
] |
[Brandon Meyer] spared no expense in
modding the Catch Phrase game to use custom word lists
. The altered version of the game, normal sold for around $25, now comes in at a whopping $230! That’s because the internals were gutted and replaced with an Arduino, 20×2 LCD display, and some other interesting bits. The device now features an SD slot for storing your own lists and a USB port for programming.
At first glance we were hoping some simple EEPROM hacking had unlocked the secrets of the device but that wasn’t he case. We’d love to see some more economical versions of [Brandon’s] prototype. Perhaps reusing the original LCD, replacing the Arduino with the ATmega168 that makes up its core, and using a
diy SD cradle
for a card reader.
So yes, this version is a bit of overkill but still very nicely done!
[Thanks Zoidberg]

building a microscopic lens from an old camcorder
. He’s using a regular digital camera with the lens set to its largest zoom level. The camera is pointed into the salvaged camcorder lens where the fine tuning is done. His first iteration was just taped to the desk with a small hand flashlight illuminating the subject. He
upgraded that setup
by building a LEGO enclosure and changing to a much brighter light source. The images he’s getting are quite surprising and this will be very useful during
those extreme hacks
when you need to tap into an IC’s internal data rails.

Electronic Key Impressioning

] |
[
"electonic",

[Barry] shared his postulation on
how electronic key impressioning works
(
google cache
). You may remember
his foil impressioning demo
from earlier in the month, but now he’s addressing a piece of news we must have missed. Apparently,
a handheld impressioning device
is about to hit the market that can tell you the key codes for a lock in a matter of seconds. [Barry’s] guessing at how this is done from his experience with a similar device aimed at car locks. When the circuit board seen above is inserted into a lock, it completes a circuit between the lock housing and the wafer. The firmware monitors the conductors on the tip of the PCB to calculate how deeply the cut should be and at what point on the key.
This would be fun to try with a homemade PCB, any idea how to deal with wrapping traces around the edge of the board like that?

The number of and vertical spacing between the traces would have to be specific to the cut depths for a particular manufacturer, and the angle of the cut off end of the board would have to be such that the effective horizontal spacing of the traces can be used to distinguish exactly which wafer is losing contact when, which is entirely dependent on the wafer spacing in the lock.Given that the board has to be tuned to the lock, the firmware won’t have but one system at a time to deal with, and all those systems are widely available without trying “thousands of locks”.Furthermore, this won’t work on double-sided/alternating/sidewinder wafer locks (most cars), or pin tumbler locks (most houses). At most, this is a shortcut for code-cutting a key for cheap-ass office furniture. As a locksmith, I’d never buy one because I can already sight-read the wafers in these locks with a pick and flashlight.",

You don’t want it to wrap around, just meet the two traces.Don’t know how durable this would be but as others have suggested, this doesn’t look like a lifelong board to begin with.

threw together a tutorial
on using serial communications in iPhone applications. It builds upon
the DevDot tutorial
which was posted back in 2007. A lot has changed since then; the firmware has come a long way and there are several development tools that now make things a bit easier for you. His examples use
Interface Builder
and
openFrameworks

Converting A Miata To All-electric

[Henry Herndon]
converted a Mazda Miata to an all-electric vehicle
. There’s a ton of great information in
his archives
, as well as a round-up video that we’ve embedded after the break. It’s interesting to see him implement two different types of Nalgene bottles as coolant reservoirs. The polycarbonate on the first shattered on him but the soft plastic replacement seems to have done the trick. The batteries add a lot of weight to the vehicle and he ends up refitting the suspension to compensate. [Henry] registered the vehicle with the state and now has a street legal EV of his own design.
Also worth a look is
his post
covering the 2009 Wayland Invitational. There as a large collection of electric vehicle conversions at the get together.

The smooth, linear, seat-of-the-pants feel of electric torque is quite simply, addicting, and it will put a big grin on your face. Couple that with the exotic whine of the gears, motor, and controller, and it will get your pulse going in a different but entirely satisfying way. Once you experience that feeling, even a relatively short range becomes acceptable. I drove an electric Ford Ranger for a couple years. “Only” 70 miles range on a nice day, but I drove it to work 35 miles round trip every day, never had to waste my time at a gas station, and instead charged it at home while I made dinner. The gas car hardly got used except for long drives. It can work, people.Kudos to the author for doing a fun car.",

Quad copters have been pretty popular for the last few years, but this one is new to us. Take the same basic layout, but bump it to 6 rotors. Then you’ll have
the hexacopter
(google
translated
). With 6 rotors, built in GPS and stabilization and a camera mounted on the bottom, this thing is pretty well equipped. You can see how agile and stable it is in the video above. We know it isn’t necessarily new, but it is new to us. Of course, you don’t have to stop at 6 rotors. You could always just
continue on to 8
.

I’ve also been interested in building a ridable version for a while, but you can’t scale a quadricopter up enough because the rotors get too big, you have to make them variable pitch instead of fixed pitch, and it just becomes more practical to make a helicopter. With this approach I can really see 8 – 10 small (12-18″) rotors working in a rideable ‘flying saucer’ configuration. Ideal power source would be nanophosphate lithium batteries but as yet they still only give a flight time of a few minutes; maybe a hybrid drive with a central ~100kW engine generating electricity to run a bunch of 10kW fixed pitch rotors?",

[Banfield Design] has put together this instructable on
how to upgrade or re build a head mounted display to be more immersive
and add features. Though you can already buy glasses style viewers for your media devices, they can use some upgrades. For one, you have to supply your own sound, and putting headphones on, over bulky glasses can be painful on your ears. Another area that could use improvement is the light that comes in around the glasses. The current trend is to make them as small as possible, but that tends to let your peripheral vision see the outside world. [Banfield design] wanted to make them more immersive, so he built them into some ski goggles. This not only helped block the light, but allowed for an over the ear style headphone assembly which is much easier on the ears.
A functional improvement came next, by adding a webcam front and center. He could now switch between a live feed of his environment and whatever other inputs he wanted. This could be really fun with some augmented reality. He has a list of future improvements, but he doesn’t mention adding a second camera for stereoscopic viewing of his surroundings. Why would you do that? because it would make
augmented reality much cooler

Trick Your Ride: Tank Conversion

"tank",

If wheels aren’t your thing you should really consider this
tank-tread retrofit
. It comes with two ramps so that you can drive your car up onto the tread platform. At first we thought this worked by chaining the vehicle’s frame to the tread frame and transferring power through a tread-mill interface. That’s not the case, it seems the transmission needs to be disconnected from the wheels and joined with the tank mechanics. Don’t miss the video antics after the break.

When you load the car on the tracks, you would support the rear (RWD) or the front (FWD) on the axel stands, then then remove the tires, and mount a pulley or chain drive (on each side) to the hub that runs the tracks.For steering and breaking you need to have a separate braking system on each track. Which is why there are two master cylinders shown in the video, one for each track. If you apply braking to one side of a diff the other will spin faster. Thus you have steering, if you brake both sides you have braking :P",

[Freeload] sent us
his custom MagSafe adapter
build for laptops. MagSafe for those unaware is Apples (patented) power adapters that prevent damage to laptops when the cord is accidentally yanked from the socket. While
we’ve seen some custom versions before
of MagSafes they were usually bulky, ugly, and used a ton of unremovable glue. We really like [Freeload’s] because its quick, good looking, and the best part – completely removable without marks or damage. In short, an easy weekend project that could one day save your laptop.

$30,000?
Is it art or is it a puzzle? Well, it functions as a game but it’s certainly a work of art and priced accordingly.
The Superplexus
was featured in
Make Mazine
and
Hammacher Schlemmer
sells it for thirty grand (you can’t just click to add it to your cart though). Think of the work that went into developing this! [via
The Awesomer
]
Rollable Display Update
[SeBsZ]
continues work on his rollable display matrix
. He’s got twenty five controller boards now and has them working as a matrix. We originally
covered this in January
but now it’s much easier to see how this can be made portable by mounting it on fabric or canvas. Check out
the demo video
if your interested.
Security testing suite
BackTrack 4 final has been released
. If you didn’t like it
when it was rough around the edges
, you should give it another try. This lean and mean Linux ditro is made for security testing and is approachable for noob and pro alike. [Thanks Steve]
Power on the go
[Csae] uses this
portable power center
to fire up some studio strobes outside. It consists of
a case
, an
uninterruptible power supply
, and a couple of extension cords
all hacked together
into one. At first you might think this is a bit ghetto but it’s portable and it does what is intended.
Happy Valentine’s Day
Giving this
LED-heart adorned shirt
as a gift is sure to make your Valentine head for the hills. This project’s a few year’s old, but
gawdy T-shirts
never go out of style, right?

IPod Shuffle Headphone Remote Reverse Engineered

The headphone remote for the third generation iPod shuffle has a special chip that identifies it to the iPod itself. [David Carne] posted
an in-depth report about the process he used to reverse engineering that protocol
. He’s discovered that the remote uses a peculiar signal to identify it as authentic when the device powers up. We’ve talked about
Apple’s use of peripheral authorization
before and it seems this is no different. [David] did manage to emulate the authentication using an ATmega88. If you’ve got a shuffle 3G sitting around this info will allow you to operate it with a microcontroller in your next project.

Apple did call it an “auth” chip once, but like the author of the linked article notes, the chip is only used to identify what controls are being used (and converting the signal so it can work with only one wire). The signal is so simple that it wouldn’t make sense for Apple to use it as a way to stop 3rd parties from making their own headphone/remote combos.Apple pisses me off for plenty of reasons, just like the rest of you, but they didn’t do anything evil here. They did not do this so you were forced to buy their hardware. The proof is out there in existing 3rd party adapters and headphones, which don’t even license the “made for ipod” mark, let alone the control chip.Again, THE CHIP IS NOT A DRM CHIP.

This arcade cabinet has been saved from a gruesome death. [Oldbitcollector] picked the broken rig up for $50 and is building a Parallax Propeller based arcade machine. This
began back in October
and he’s
just dropped in a newly painted control panel
to replace the NES controller seen above. He pulled the replacement screen out of an old 19″ TV and found it to be a perfect fit. We didn’t find a complete list of available games but we know he’s got a menu system to choose the game and have seen Donkey Kong, Frogger, Defender, and at least one other in the videos. There’s less choices than
a MAME cabinet
but who needs more than a handful of the old 8-bit gems anyway?

Workshop Tour Makes Us Drool; Ache With Envy
|
Mike Szczys

[
"Misc Hacks"

[
"workshop"
] |
[Mtneer_man] has
a workshop to die for
. The
slide show
that he set up covers the different workbenches and shop setups that he’s had over the years. He’s got a core set of beliefs when it comes to his work area. He prefers to have several different work areas for varying degrees of dirty, greasy, stick, or precision projects. These are luxuries that most don’t have the opportunity to enjoy.
With a setup this nice and this clean it’s amazing he does any projects at all. Wait a sec,his workshop IS a hack. The more recent collections of
his prolific Flickr sets
he details the building and outfitting of yet another workshop in a new structure on his property. We’re going to keep our eyes on this and see where it ends up.

Transparent Rubber Enclosures
|

This clear rubber puck
serves as the enclosure for a diy mp3 player. The wires encapsulated in the rubber are just there for looks but the utility of using this material as a case is fascinating.
Alas, there’s no details on the material other than that it’s clear rubber
.
Update:
[Reboots] picked up on
some info
that we originally missed. Looks like this is made from some
Smooth-On PCM 780
urethane rubber.
We’ve looked into casting our own molds from silicone rubber in the past. That may be the process used here but we can’t tell what allows the two halves to be pried apart. We’ve embedded video after the break that details casting rubber around a part in one solid block, then cutting the rubber off of that to create a mold. We’re also familiar with the
mold making kits from Tap plastics
but as far as we know, they’re always colored and never clear.
We keep our eyes peeled for
new prototyping products
and we want to know more about the materials and the process used to make this cylindrical elastomer. If you’ve got the goods on how this is done, please share them in the comments.

"content": "I’ve used hot glue to “pot” many a small connector/adapter. If you just need a way to protect and give a durable shell to a simple circuit (that won’t ever require modifications), not a whole lot can beat hot glue as a solution. One way to get clean faces is “thermal” mats — heat-proof rubber mats often sold at hobby shops to protect your table also have the tendency to not allow hardened glue to stick to them. With a small enough application, you can just apply the glue one side at a time, using the mat to provide a flat edge. It works in a pinch, though finding a better form is a good idea for anything much larger than a little dead-bug circuitry.",

Internet Controlled Scrolling Numitron

How’s this for a first microcontroller project:
a ticker that pulls messages from the Internet and scrolls them on a set of numitrons
. [David Barton] built this using an
mbed microcontroller
. Tapping an ethernet library he got this to pull data from his server by connecting directly to the cat5 cables. The display consists of three numitrons which are incandescent 7-segment displays. In the video after the break you can see him sending messages to it from his iPod touch. This is just a PHP form that writes the submitted message to a file for the mbed to read. As [David] points out, there’s obvious Twittering applications here, but we just like the way it looks!

Spectrum Analyzer Wedged Into A Cellphone

[Miguel A. Vallejo] wanted a portable spectrum analyzer for the 2.4GHz ISM band. No problem, there’s modules for that are easy to interface with a microcontroller and LCD screen. But carrying around a black project box doesn’t exactly scream ‘cool’ so
he fit his spectrum analyzer inside of a cell phone
. This made a lot of things easier for him; he already had a few old phones, he was able to use both the original battery and the original LCD screen, and a lot of the mounting work is already done for you. The only challenge was to fit his custom circuitry inside. By hacking off part of the CYWM6935 module and cutting some protoboard in the same shape as the original PCB he managed to get everything into this tiny portable package. Now he’s looking for a way to incorporate a charger, and an on/off switch.
If you don’t have an old cell phone sitting around you can
try building a spectrum analyzer that uses a character display
. But we’d suggest hitting up your friends for their old cellphones. The screens are used in
all kinds
of fun
projects
.

Check out the exoskeleton that [Curt von Badinski]
built for filming driving scenes
. This extremely configurable wrap-around frame resembles a
children’s toy from the past
but allows an almost unlimited set of configurations. Five cameras simultaneous capture the driving scene. The current setup is used to shoot the television show 24.

Chip And Pin Broken And Other Security Threats

"pin and chip",

Another exploit has been found in the Chip and PIN system. The exploit is a man-in-the middle attack that wouldn’t take too much know-how to pull off. You can
watch the BBC report
on the issue or
check out the paper
(PDF) published by the team that found the vulnerability. A stolen card resides in a reader that connects to a dummy card via a small cable. When the dummy card is inserted into a card reader, any PIN can be used to complete the transaction. The chip on the original card gets confirmation that the sale was completed via signature and the vendor’s card reader gets confirmation that the pin was correct. The UK based
Chip and PIN
system seems like a great idea, but it has had its share of
security loopholes
. This makes us wonder how hard it is to roll out security patches to the hardware readers in the system. Obviously this needs to be patch but does it take a technician visiting each terminal to flash an upgrade?
Switching to the topic of wide-scale attacks, we caught the
NPR interview
with [James Lewis] on Wednesday when they discussed the growing threat of Cyberterroism. He feels an attack on the US electrical grid is currently the biggest threat and will happen in the next ten years. Obviously taking the grid down would endanger lives and bring things to a standstill; traffic lights, refrigeration, heat, etc. We’re just glad that when asked if he thinks there is already malicious code residing in the control system, he doesn’t think that’s the case.

Last week it was out at work for the first time in 3 years or so, due to someone running into a power pole.45 minutes away in the mountains, where my parents live, it happens all the time and they own a generator, but here it just doesn’t make sense.If all of silicon valley lost power though, it would be a serious problem after not too long.It has nothing to do with people being too “cheap”, it just doesn’t make sense for plenty of people, and that’s why on the rare chance our whole power grid went down, it could in fact be a big problem.It would certainly hurt us economically, and that’s all terrorists really want anyway, as it weakens us.-Taylor",

The idea of a distributed “smart-grid” which can utilize power generated from a variety of sources is intriguing.The use of renewable energies like grid-tied photovoltaic systems on homes and businesses could help provide a more reliable and secure electricity infrastructure. Mainly due to the distributed, “point-of-use” production in such a system.Plus, if the grid were to somehow fail, many people would still have access to the electricity from their own photovoltaic systems (and presumably, large battery-backup systems).

Teletype Machine From An Electric Typewriter

This project, by an unknown hacker,
patches into an electric typewriter and uses it as a Teletype
. An AVR ATmega168 microcontroller patches into the key matrix of the typewriter which allows it to artificially type. Now, data can be sent over a serial connection to the AVR for output on the typewriter.
We’re not quite sure what this is going to be used for. We’ve seen
hacks like this for Twitter reading
in the past but he makes no mention of that type of use. Personally, we’d like to have this just to “print” out the occasional letter. Typewriters are so rarely used these days it would be a bit peculiar to get a letter that has the dimpled impressions associated with slamming a die into a piece of paper.

We’re not going to debate the necessity of this one. [Todd] plays online games that will log you out after a few minutes of inactivity. To resolve this, he has created a
circuit that mimics keyboard activity
at a preset interval. While he notes that there is software for this, he points out that many games block the software. They can’t block legitimate keyboard activity.

This tip was submitted by [Mike], with the original information
seen in this post
. When I passed the story along to our writer [Mike Szczys] I didn’t send along the entire email conversation. This bot is noteworthy because it has taught itself to walk. In the
build log
you can learn about how it has created its gait and altered it based off of the vision. There are also some great pictures of prototypes there too. While we can all agree that it isn’t as impressive looking initially as the A-Pod, remember that it wasn’t programmed to look impressive.

Mars doesn’t really work well for wheeled rovers because of all the rocks, but a bigger version of this could possibly even RUN on the surface.

You could add more legs and make them detachable, etc., but I can’t see how a set of legs would last longer than the wheels that allowed the Spirit to move for more than 21 times the intended length of time.A shorter and much more humorous explanation is available athttp://xckd.com/695/.Also, what’s wrong with GLaDOS? :(",

Even if 10 motors failed, the other 8 could still move.Pre-programmed algorithms would certainly fail if a single motor would fail, but learning allows relearning of complex new geometric configurations. In other words, the hexapod walks around, a rock can crush two legs, and then the hexapod relearns how to walk with its new configuration.So then why haven’t we integrated this already? Learning takes time and energy for experimentation and even in simulation. Current learning techniques certainly need to be made more efficient.",

HUD For Real Life Capture-the-flag

If you’ve played any of the Splinter Cell games you’ll remember the PDA that [Sam Fisher] carried around with him. What if you could have one of your own when playing capture-the-flag? [Brad] has created the
ZephyrEye as an electronic command and communications device for real-life games
.
Each player carries around their own unit. The ZephyrEye has a GPS module, Xbee module, LCD screen, and control buttons. This allows a player to setup one of several different games, map out the game field including base locations and flag locations, and monitor a time limit and scoring. Other players can join the game in progress. The best part? The GPS modules report tracking to each handheld and act as radar for your team and the enemy team. We’ve got a couple of demo videos after the break.
Words can’t describe how delighted this would have made us back in the day. We don’t play outside with the other neighborhood kids anymore (insert dirty-old-man joke here) but that might change just because of this device. We may end up joining [
Barney Stinson
] for some amazingly awesome laser-tag games after all.
[Brad’s] posted hardware information and source code so that you can use to throw together a dozen or so units. We think the next version should incorporate
a wearable display
.

Veteran Robot Features Eight Legs And BeagleBoard

This spider-bot was built by [Zhanx] during his deployment in Iraq. He didn’t have prior hardware building experience and started out on this project when he received an Arduino to play with in September. Must be a fast learner! The parts are laser-cut from ABS plastic and connected to 24 servos. He sourced an
SSC-32 serial servo control board
to take care of the motor connections.
[Zhanx] has since migrated from the Arduino to a
BeagleBoard
which you can see perched atop the body in the video after the break. This should give him plenty of speed and power to improve the movement routines. There’s some nice work here but adding rubber feet, like on
yesterday’s hexapod
, wouldn’t hurt.

[Mike Bradley] wanted to use his oscilloscope to display 8 channels of digital signals. Alas, the analog unit didn’t have this capability. Not to worry,
he threw together an adapter module
that does the trick. Using a PIC 18F26K20 microcontroller he inputs four or eight channel digital logic (at 5V) and filters the output to an analog signal that the oscilloscope can interpret. What you see in the photo above is the result.

How does it choose the timebase? It looks like assumes a moderate timebase (presumably chosen to give a non flickering trace on the scope), and you can ‘zoom in’ further if you need to by adjusting the scopes time base.2. How does it deal with synchronizing the trigger? It seems like if this is to be used for a logic analyzer of sorts this would be a big issue, and as it is it doesn’t seem like it does much to synchronize the traces in absolute time (not just starting at a random clock bit for each trace) unless it is storing a capture, then displaying it.Sadly since I have a digital scope this would be somewhat tricky to use, since you can’t trick the CRT into working like an analog does.",

As it appears he can draw 8 digital channels with a single channel on the scope, the second channel could be used for something else.When you store the signals, it would be fairly easy to send them to a PC and use some tool (possible just Excel / Oo Calc) to draw the waveforms for use in documentation.",

It has seemingly identical hardware, with some work I bet a filter can be found on the analog frontend that limits the bandwidth. Additionally, there is a logic analyzer version that costs something like $1k, rather than $400 on dealextreme.com for this one. It looks very very similar.. if you open up the DS1052E there is a header for the logic analyzer going to a PLL. There’s a button that enables it which doesn’t appear on the outside, but has been cut out of the rubber button set on the inside. If pressed, it says “feature not installed” but the firmware seems to be the same. Lots of hacking potential, and a good scope with a 3 year warranty otherwise.",

[Dwight’s] been working on a long-term project to
add a status board for the ski runs at Copper Mountain
ski resort. The board will feature an 8×8 LED module for each run that displays a green O for open trails, a green G for groomed trails, and a red X for closed trails. He’s also got a status board with LEDs embedded in a trail map.
The system relies on SPI for each LED module. An Arduino Mega uses a Xbee module to pull down XML data wirelessly and display it on this board. Since
the trail report is already available online
it’s just a matter of parsing the data in a useful way.
He’s not quite done with the whole thing yet, but keep an eye out for it if you are planning to ski Copper Mountain.

[Carl] sure has come a long way with laser modifications, now introducing his portable
RGV Full Colour Laser
. Although it feels just like yesterday when he showed us his
green spiro
and his
Lego diffraction grating projector
.
But enough of the past, the RGV laser is built using a
White Fusion Mixing Kit
and his own
Full Colour Driver Extension
. We couldn’t find any circuit diagrams or code to build your own at the moment, but it appears fairly straight forward and you can always take a look at
[c4r0’s] Colour Laser
.

[TomTheGeek]
built a LEGO tank with a PicAxe controller
. Locomotion is supplied by a Lego Power Function motor controller. He cut an LPF extension wire in half so that he could patch into the PWM signals without altering the motors themselves. You can make out the control circuitry and a small breadboard in the tank’s turret. [Tom] added a laser pointer to the tip of the barrel but we’d like to see an IR LED. The tank is controlled by a infrared remote control and adding TV-b-gone functionality to the toy would create something of a
Rube Goldberg feature
for turning off the tube. But alas, there’s no programming space left for that as the PicAxe 08M is limited to 256 bytes.
There’s a video after the break of this little demon tracking its way around the room. This is a nice addition to
the other LEGO tank
we saw a while back.

USB Host Mode For Droid
|
Mike Szczys

[
"droid",
"usb host"
] |
There’s a simple hack to
use your Motorola Droid phone as a USB host
. It is a hardware-only hack that doesn’t require you to crack open your phone,
root it
, or even to change firmware (although device drivers in the stock Android image may be quite limited). The dongle above is used as a key to enable the mode while the phone is booting. This was repurposed from a car charging cable by removing the wires and resistor and shorting the resistor pads. Once the phone is in host mode the dongle is swapped for a simple USB-mini to USB-A socket adapter, built from two cables you probably have lying around. Now you can plug in any device you want.

Got it here:http://www.lindy-usa.com/2m-usb-otg-cable-transparent-type-mini-a-to-mini-b/31634.htmlOf course, sadly, i think the droid is Micro USB, isn’t it?And I did notice that it plugs into my G1 (USB OTG is shaped differently and won’t plug into a normal USB mini jack, to avoid confusion), I wonder if it has this mode?I’ll try it out and report back, but work is busy so I don’t know when that will be!-Taylor",

The simplest solution is to use the existing cmos camera and just extend the cable. In other words, remove the camera from the phone and reconnect it with a cable long enough to allow the camera to be clipped or glued to a hat.I think a bluetooth connection is more desirable in a lot of ways, but I have no clue how to make that happen.So I bought a parts droid on ebay and took it apart. The camera and mini board consist of a ccd camera module and what appears to be a 38? pin connector. My idea is/was simple. Cut the cable which ties the ccd board to the 38 pin connector and fabricate an extension cable then plug the camera back into the testbed and see if it works.Unfortunately, I’ve hit a snag. The wiring in the cable is VEEERY tiny and possibly double layered. The wiring appears thinner than a sharp knife, so that the whole measurement of the connector is less than the width of my pinky nail. But someone or more likely some machine made this which makes me think someone or some machine could fabricate an extension cable.Does anyone here have any ideas who to consult with or how to approach solving this problem of fabricating an extension cable?",

However I have made the first mini usb cable with the shorted data cables and plugged it in. After that I pulled the cable out of the phone when the Motorola logo disappeared.

Dexterous Hexapod Rocks An Atom Processor

[Matt Bunting’s]
hexapod caught Intel’s eye
(and their wallet). This coordinated little bot runs Ubuntu on an Atom Z530 processor, popular in netbooks like the Dell Mini 10, and uses a webcam to coordinate and monitor its motion. Intel picked up two of them from [Matt] to exhibit at trade shows. As you can see, the 18 servos provide some gorgeous motion to the beast. It’s no
DJ Roomba
but it approaches the zen-like perfection that is
the A-Pod
.

The Day After Arduino
|

|
[
"Arduino Hacks"
] |
[
"arduino",
"breadboard"
] |
There will come a day in every budding hacker’s life that they realize that plopping an entire arduino in their project and leaving it there is a bit of a waste. [Domiflichi] realized this, and
has shared his next steps with us
. He takes us through the process of removing the ATMega chip and breadboarding it for final use.
For many of you, this is an obvious chain of events. However, there are also many who just haven’t ventured forward and taken this one step that will forever change how their projects are seen by the hacking world. For the anti-arduino crowd, realize that this is an opportunity not to bash a useful tool but to help nurture and lead people to the next step.

If the resources are there he/she will use them to do so.Don’t forget that for many of us this is a hobby not a profession so jumping through flaming hoops is not desirable. a little paving here and there is welcome!Having said all this is the *only* negative thing I have seen about the arduino + related so far.

But I still think the toolchain thing is the weakest link, from a free/cheap pov. Still, the demo versions referenced provide enough to create some decent projects.",

"content": "To those jumping on me for my comment up there. Perhaps I should’ve put it differently. What I meant was simply that it would probably be an eye opener for those who have never used anything but the ready made libraries and the like. You gain more space and often speed as well (well, probably not at first but when you learn a few tricks along the way). If you always rely on the availability of libraries you never learn to solve problems on your own.I didn’t mean that they should be forced to learn ASM (I started with that, got fed up and put down the hobby for months until I started back up with C). I’m all for ease of development but it doesn’t hurt to know how to do more powerful stuff.The post is about moving away from the traditional Arduino boards, so, isn’t the next logical step to also move along to a “real” language? (and please, don’t stab me in the neck for that comment as well, you know what I mean)",

If you are custom designing boards, you aren’t hacking anymore, you are designing. The prototype IS the hack, the refined and optimized version of the prototype is losing the hacked qualities and becoming a formal project.That being said, the arduino is a swiss army knife and easily overkill for many projects.

Have you ever felt like you needed a portable barcode scanner around the house? No? Well, [Mkanoap] did,
so he made one
. He has hooked his
CueCat
up to his Arduino to capture barcode data and store it on an SD card. He is using it as an inventory tool for his personal library. Where before he had to carry a laptop around to do his scanning, or lug the books to his desk, he now just scans wherever he pleases.
You may notice some silly sounds dubbed over the video. Take note, these are the actual sounds it plays. The camera didn’t pick them up well enough, so he dubbed them in. You wouldn’t want to miss out on the entire experience would you?

Im not talking about for myself, its for resell geniuses.This would be by far the cheapest way to implement, far cheaper than buying a cellphone.Ultimately the arduino could be replaced?by components, write some code, gather AMZN database, and boomIts definitely interesting to me as there are 20 or so business that sell subscriptions to such devices for anywhere from $20-$60 per month per device.Yes, its not a laser, but it woulud be WAY faster than using your camera fon to take a picture 5 times before it got it right and another 30 seconds to 2 minutes to get the results back..No thankx, Id rather scan it and know in a few seconds and move onto the next possible item for resell.Could you imagine scanning thousands of books in one day via your cellphone camera? Have fun with that!",

It certainly doesn’t sound like it, as that isn’t at all what my experience has been with any of the ones I have run on the Droid.You don’t actually take a picture of the bar code, first of all. The software processes a live video stream, so you just point the camera at the code and it picks it up. You don’t need to repeatedly take single pictures; and returned results are near instantaneous on 3G, and even if you were stuck on a 2G network it wouldn’t take 2 minutes to return a item lookup.In fact, there is at least one commercial inventory management tool on the Android Marketplace that is designed for exactly what you are getting at; small businesses that don’t have the money to spend on a dedicated inventory system.Also, you don’t need to actually have a cell phone contract to get a smartphone, that is why I said get one on eBay. You can buy one outright on eBay, install the software over WiFi, and use it to your heart’s content without ever connecting it to a carrier.

Tom Shannon
] uses science as part of his art. One of his methods when painting is to use this radio controlled paint pendulum. He gave
an interview at his studio
, which we’ve embedded after the break, and goes into detail about this device. It has six different reservoirs that hold the paint colors. Each gravity-fed canister connects to a central nozzle with flexible tubing. The hand held control box has a slider for each color that moves a servo pinching each supply tube. This ingenuity keeps him creating even though Parkinson’s Disease has started to manifest itself with tremors in his hands.
It’s hard to make out the paintings seen above, but the ones on display in the video are pretty amazing. He mentions that anything can be loaded into the hoppers, including tomato sauce. Is anyone else thinking about
large scale pizza constuction
? This also reminds us of the
mechanical bartenders
we’ve
seen in the past

TPM Crytography Cracked

Trusted Platform Module based cryptography protects your secrets as well as your government’s secrets. Well, it used to. [Christopher Tarnovsky]
figured out how to defeat the hardware
by spying on its communications. This requires physical access so it’s not quite as bad as it sounds, but this does reach beyond TPM to many of the security chips made by Infineon. This includes peripheral security chips for Xbox 360 and some chips used in cell phones and satellite TV.
[Christopher] revealed his hack during
his presentation at Black Hat 2010
. The method is wicked-hard, involving removal of the chip’s case and top layer, then tapping into a data bus to get at unencrypted data. The chip still has some tricks up its sleeve and includes firmware traps that keep a look out for this type of attack, shutting down if it’s detected. Infineon commented that they knew this was possible but regard it as a low threat due to the high skill level necessary for success.
[Thanks Greg]

This looks like a home entertainment center of yore but something’s not quite right. Where is the turntable used to play the music? It turns out that this
Danforth Standard Digitrola
is digital and doesn’t rely upon wax for an input. [Jonathan Danforth] built it as a show piece and it exhibits fine craftsmanship. A sound driver uses the brass horn and the acoustical chamber to put out what sounds like a fine quality end product. Hear it playing some
Daft Punk
in the video after the break. The music comes from an MP3 board inside that has a 50W amplifier and reads the music from an SD card. The only control available to the listener is the brass knob which controls the volume.

Each one will contain an entire genre of music including hundreds of tracks.Thanks for the tip on the bass port! The mic in the little digicam I was using might be the source of the distortion though. It generally sounds pretty clean the way I’ve equalized it.By the way, I’m working on console TV featuring a 6″ diagonal LCD now. :-D It will be very art-deco and feature Ambonya burl facing.",

Porta Touch: Portable Multitouch

We just found this great
portable multitouch rig called the portatouch
. Made by a user at the NUI group website named [portatouch], this system uses a stripped down LCD as the display with IR LEDs edge lighting a touch surface in front of it. A camera mounted below the LCD picks up the reflections of the LEDs and converts it to touch points. While the implementation isn’t anything new, the package is really great. If you want to learn how to set up the technical side of it all, head over to the
NUI group website
and you’ll find all you want. We would love to see a more detailed breakdown of his rig though. The portability and quick construction are fantastic and seem like they could be reproduced without a ton of custom work.

‘tiny’ Power Supply Monitor

[Manekinen]
built a power supply monitor
based around an AVR ATtiny13. Voltage and amperage are displayed on a 16×2 LCD character display (we’re not sure what the third number is… samples per second?). This is no small feat considering that the tiny13 is an 8-pin chip. He makes it happen by using the pins for both LCD control and ADC input. To make this happen the HD44780 compliant display is used in 4-bit mode. Check out the video after the break and hit up
the non-translated page
if you want to download the source code and PCB artwork. A note of warning, he’s using the RESET pin for I/O which means once you burn the fuses you’ll need a
programmer that has High Voltage
Serial Programming capabilities if you want to reprogram the chip.

“Everyone needs a hobby,” they tell us. For the blogger mysteriously identified only as “R,” that hobby would be
an almost fanatical nostalgia for the Commodore 64 computer
.
At first we thought this was a fan community site, but apparently it’s all the work of a single person. [R] has tweaked, extended, repackaged and resurfaced this 1980’s icon in nearly every imaginable way. They tend to gloss over the technical aspects of these mods, but that’s okay – the C64 is such an
exhaustively
documented
system
now that the site dwells mainly on the
aesthetics
and meaning of these reborn devices.
The 64 has made an indelible impression on
electronic music
, and the machines are still sought after by collectors, composers and
circuit-benders

GuruPlug, The Next Generation Of SheevaPlug
|
Mike Szczys

"sheevaplug"
] |
Meet GuruPlug, an all-in-one server that is
now available for pre-order
. This is the next generation of the popular
SheevaPlug
that features some added goodies. The base model sells for the same $99 and appears to have the same specs as the original but for $30 more, the GuruPlug Server PLUS moves to 2 Gigabit Ethernet ports, one eSATA connector, and built-in WiFi and Bluetooth. All of this for $129 and it only pulls 5 watts? Wow.
Update:
Thanks to [Foerdi] and to [
Phil Burgess
] for the pointing out that the hardware diagram on
the features page
shows WiFi and Bluetooth for
both
models.
[Thanks Chris]

Reading these comments is half interesting, half hysterical.As I write this, the GuruPlug plus has been removed from the website. Too bad, the two Ethernet ports made it useful for a firewall, which the standard GuruPlug I’m playing with. I have an actual application for the “DreamPlug” and will be working with that next. The question isn’t if they’re worth $99 or $149 respectively, but what the quantity pricing is. Example: the $99 (onsey) Sheevaplug is being resold as a “Pen Test” appliance on Amazon for $500+. Not a bad markup. But also _not_ a good example of _creatively_ applying these in a product.",

[Oliver] has been doing some work to
use his TI ez430 Chronos wristwatch for some home automation
. He’s working with a RF controllable lightbulb adapter which operates in the 433 MHz band. A dirt-cheap breadboard-friendly transmitter is
available from Seeed Studios
and he uses this in conjunction with a computer and an Arduino. Before the trolls get to their thing, YES, this is incredible overkill. But remember that he’s prototyping. We hope that if he intends to actually use this setup he’ll migrate to something like an ATtiny2313 running
V-USB
. Better yet, you should be able to tap into the watch’s companion receiver and cut the computer out completely.
If you’re easily amused you’ll appreciate the video of a light turning on and off after the break. If you’re a little harder to please then take a look at
Oliver’s methods of using Python processing
for the watch’s data.
Ok, now we’ve seen
this watch
turning on lights and
unlocking doors
. What else ‘ya got?

Built-in Hex Editor Unlocks Plasma TV Features

"hex editor",

"settings"

[Nick] tipped us off about a guide to
unlock extra features on Panasonic televisions
. The hack works on the G10 models of plasma TVs and uses the service menu to gain access to the EEPROM memory. With a few quick steps you can change some data with a built in hex editor, unlocking several new settings menus, or bricking your entertainment centerpiece. We’ve seen some
Samsung TV
hacking in the past and hope that with increased processing power in today’s models we’ll someday see consumer TVs available with open-source firmware so that we can integrate of
our favorite entertainment software
.

Just when you think you’ve heard all you can about the N900 PUSH competition, we have some more news for you.
The original PUSH competition was only for UK members, but now Nokia has introduced the ‘
Mod in the USA
‘ N900 PUSH competition. Similar to
the original
, anyone (within region) can
submit
a cool mod, hack, useful creation that would use the N900. Winners will be selected, and thats when the differences start.
There will be a $10,000 for 1st prize, and smaller prizes for 2nd and 3rd. Plus a trip to Vegas to showcase the 3 winning hacks at CTIA 2010 as well as funding, N900s and support to build the mods.
Don’t have an idea but still want to try? They have a
discussion group
to get the juices flowing, or you could always discuss in our comments.
[Update: The original PUSH competition was actually world wide. Thanks Matt and Ricardo]

FAT Support For Any Microcontroller
|
Mike Szczys
|
[
"Misc Hacks"
] |
[
"efsl",
"fat",
"microcontroller"
] |
[Rahul Sapre] sent us
a guide to porting EFSL to any microcontroller (PDF)
. The
Embedded Filesystems Library
adds FAT support to C compiled microcontrollers. It is targeted at the AVR line of chips but can be adapted to any architecture that works with a C compiler. [Rahul’s] guide will take you through the process of adapting the latest stable 0.2.8 version to new hardware by using a PIC uC as the working example. The non-stable
development branch of EFSL
is working toward multiple-platform support so consider lending a hand if this interests you.

Bot gives head to passersby
This
free range robot
was spotted at this year’s Kinetica Art Fair. You can place your hand above it and it will stop and pour you a beer. That’s if you consider 7/8 of a glass of head ‘a beer’.
Photo booth adds fun – consumes floor space
Face it, photo booths are fun, and if they’re free a lot of people will use them.
This particular booth
was built in some guy’s apartment, adding the fun but eating up floor space. But this would be a great build for your next group gathering, just like the
Crushtoberfest
. [via
DVICE
]
More human through-hole design
[Fridgehead]
stuck and 5mm LED in his earlobe
and then used a microcontroller to make it pulse. He’s got quite a mop and that’s where he hides the black controller pack. The next version should be RGB and the smallest surface mount packages he can solder. At least this isn’t disgusting like the
LED nipple ring
.
Chandelier your wife will never let you install
This
300 LED chandelier
uses epoxy coated wires draped around the light ring to resemble a more traditional crystal light fixture. It’ll still be a hard sell if you want to hang this over the dinner table. [via
Gizmodo
]
A touch of copper
[Zombie84] built a
prototype of a robot arm
out of copper pipe. There’s not much info here, but you can see some wires in the wrist that appear to function as tendons. This reminds us of the characters from
9

Let’s face it, walking around in the rain sucks. [Matth3w] is trying to add a little whimsy to an unpleasant experience by
adding an LED matrix to his umbrella
. The array contains 80 LEDs that are individually addressable. This is a mutiplexed array that relies on a MIC2981 source driver for the eight rows (or rings in this case), with the ten columns handled by the Arduino. The effect is quite nice as you can see in the video after the break. Now that he’s proven this works, you might want to etch your own PCB in order to get rid of the Arduino board and prototyping shield, making it easier to waterproof the control circuitry. This would make a nice addition to your
illuminated umbrella stock
.

[Mario the Magician] wrote in to let us know that he makes Hackaday a priority every morning with his coffee. Well, so do we. He also included
a link to his homepage
when submitting this revelation. The juicy details that are as much of a fix as the caffeine in the coffee are missing from his posts. But the hacks are solid.
Magicians are hackers. If you could go out and buy the props, the concept are unlikely to impress anyone. [Mario] demonstrates his
Nickel Box
and a
Jedi Mind Trick
he built. The Nickel Box is a mechanical contraption that somehow transports a coin from one part of a cigar box to a tiny little enclosure on top of it. The Jedi Mind Trick uses a microcontroller and an old Star Wars soundtrack cassette tape box to put on a light and sound show while it recovers your chosen card from a shuffled deck. Great demonstrations, but no word on what’s going on inside.
[Mario’s] also has a collection of… performance oddities. His
talking television
takes an audio input and displays a 1950’s-esque oscilloscope effect on an old TV. He’s attempting to stop his heart, or burn the house down, or both with a flyback transformer
lightning box
. And his
drawing automaton
, well, you’ll just have to see it.
We believe in electrons, not magic (even though some say
there are no electrons
). So we want to know how those magic props are built. Like any good magician, [Mario] probably won’t reveal his secrets. If you’ve got the goods this your chance. Write a post detailing your magical prop builds and
send them our way
.
If it’s well done
we’ll feature it here on Hackaday.

He gives it a little shake, mentioning that it’s “an old box”, and that deposits the nickel into his hand. Watch his hand as he takes it away – it’s closed tightly as if he’s holding something. He deposits it in the small box that closed with a rubber band (so he can just slide it in). The coin is in there as he places it atop the nickel box, and then he just uses a previously-marked nickel inside the bigger box, which is shown to the camera.",

ExoPC Shows Off Some Guts
|

"touchbook",
"windows"
] |
The folks over at Engadget have posted some
pictures of the ExoPC’s insides
. With the recent return of the tablet craze (remember xp tablet edition?) we’re seeing tablets everywhere. This one has some promise on the hardware side, sporting a 1.6GHz processor and 2GB of RAM. Unfortunately we’ve heard using solely a tablet interface with windows7 is somewhat cumbersome even with the built in improvements. We’re not too worried though, a customized appliance style linux interface probably won’t be too far off.
The last couple times we mentioned tablet style computing, people have emailed us about the
Touchbook
. It also seems pretty cool, but seems like switching applications is visibly laggy in the demo video. Then again, a slimmed down interface might reduce some of that drag.

Altoids Upstaged By Gift Card Tins

Nothing Earth-shattering here. Just, dare we say it,
really cute!
The venerable Altoids mint tin has become an icon of the maker culture. Browsing through past articles on Hack a Day, Adafruit or Instructables, you’ll find project after project for which these pocket-sized enclosures provided just the right fit. Eminently practical, affordable, but the aesthetics have occasionally left something to be desired.
We recently stumbled upon these nifty gift card holders that resemble miniature versions of current-generation game consoles. They might be the perfect housing for your next microcontroller project…
These were acquired from our local
GameStop
retail store and unfortunately do not appear to be available online. Each will set you back $2.99 — about a buck more than the mints, and without the added benefit of fresh breath. Such is the price of style.
The shapes are varied, but all are a bit larger than the traditional Altoids tin, allowing ample space for a
battery pack
,
breadboard
or
microcontroller
setup. As with the mint tins, of course you’ll want to insulate your project from the interior metal surface. A bit of contact paper or even some index cards are usually sufficient.
In addition to the
Xbox 360
,
Wii
and
Playstation 3
tins depicted here, portable consoles — the
PSP
and
Nintendo DS Lite
— are also available in miniature form.

We like to run the newest software available. We often encounter problems and things that don’t work because of this, but with open source that just give you the opportunity to contribute and make the package better. Now you can take the fun and daring of bleeding edge to your phone by
installing the latest Linux kernel on the Nexus One
. [Jon Lech Johansen] wrote up that eight step process to install 2.6.32, which should take you just minutes if you already have the Android SDK installed. If you don’t what are you waiting for?

Interfacing With An Analog Joystick

[
"analog",
"basic stamp 2",
"boe-bot",
"bs2",
"Joystick",
"variable resistor"
] |
[Firestorm_x1] put together
a tutorial about interfacing an analog joystick with a microcontroller
. These analog sticks are easy to find; he got his from Goodwill but we’ve got a couple in our junk box right now. The stick uses variable resistors to report its position so it’s just a matter of reading and interpreting that data. After explaining the concepts he demonstrates how to use the joystick to control a Basic Stamp 2 based robot, the Boe-Bot. This could easily be adapted for use with
other robot platforms
.

Not too long ago
we asked our readers
what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
The day has passed, the
party is gone
, and all that’s left is the final interview. The
Light Hack Crew
gave us a somewhat shorter response then what we were used to, but it turned out to be just as sweet.
>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.
>How did you and your team get together? Any fun backstory you care to share?
LIGHTHACK CREW is a trio of 3 crazy coconuts from Perth, Australia . [Dave] and [Tom] have been friends from way back, and [Sharna] is a friend from way, way back,
>Have you and your team worked on any other projects? Cellular related projects? N900 projects?
No this is our first one together.
>What was your main inspiration for your team’s project?
It was [Tom’s] idea for focusing the project of light graffiti, and that made me think of [Sharna] as she is a graffiti stencil artist.
> How do you think people will react when you finish/release?
People will love it as it is fun to create light graffiti and easy to do, all you need is the hacked N900 and the electronic LED can.
>Do you have any future plans with your team? Continued N900 development? Update your current projects?
Hopefully continued development of the Light Hack software and bring it to other devices
>What do you think of the other winners?
well as a skater, long boards mainly, I’m interested in the soldering skaters team, the others are great too,
>Questions from our commentators.
>What are you thoughts on Arduino? Do you intend to use one in your project?
[Tom] is the electronic genius, but I’d say he found the Arduino pretty straightforward.
>How is working with the N900 hardware and software?
Great from the little I have looked at and used, the phone is very powerful, its not running a snapdragon but damn can it multi task! the open source Maemo OS is very cool, the fact that it is linux makes it so much easier to develop for, as so much is setup for it already – SDK installed VM image is the way to go.
>What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android?
I think its great, I tried the iphone, but objective C was new to me, along with the $100!, haven’t had the time for android yet. But would like to check it out.
>(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project?
We use 4 AA or 4 AAA batteries at the moment. Im sure we could wire up any sort of battery. The battery life isn’t too bad, as the Bluetooth really only is used when the buttons are pressed, and the LED’s are quite efficient.
>Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc)
HARDWARE: Bluetooth module, PIC microcontroller
SOFTWARE: I used C, for the language, GStreamer framework for capturing the video, and some basic algorithms for image processing: subtraction and a moving average filter for noise removal.
>And yes, we actually had a reader (Joe) ask the following (feel free to omit)
>How often do you change your underwear? Underwear?
Its 38 degrees im just wearing my boardies J
Thank you again!

Guitar Hero As An Instrument Or Midi Controller
|

"controller",
"guitar hero",
"max",
"midi",
"msp"
] |
[youtube=http://www.youtube.com/watch?v=azfgasnWtW0]
[Robert] wrote a program using Max/MSP that
lets him make music with his guitar hero controller
. There’s another video after the break where he walks through the various features but here’s the gist of it. This works on Mac and Windows and allows a sort of ‘live play’ or midi mapping mode. In the midi mode each key can be configured to do your bidding. His example uses the pick bar to scroll through different samples and the green button the play them or the red button to stop.
The live mode us much more involved. In the software you choose the type of scale and the key you’d like to play in. This makes up for the controller’s lack of enough frets to make it a chromatic instrument and these settings can be adjust from the controller. There is an up-pick offset that makes the upward movement of the pick bar a different note than the downward movement. The motion control can also be used as an input. He
demonstrates pitch bending and cutoff
using that method.
This looks like a lot of fun. He needs to team up with [Joran] to
add drums to the mix
, forming a much more creative rock band than you can buy in the store.

Battery Holder Reuses Blister Pack
|

"a23",
"altoids",
"battery",
"blister pack",
"minty"
] |
In need of a portable power supply, [Alastair]
threw some batteries into an Altoids tin
. The problem was he didn’t have a holder for these size A23 cells. Inspiration struck and he realized the blister pack they came in fits them snuggly and just needs some conductors to complete the circuit. He pulled some battery contacts from a broken CD player. Using foam-based double-stick tape he added some spring to the contacts and came up with a perfectly sized holder that works wonderfully.
We’ve tried making battery packs by wrapping the entire thing in clods of duct tape. This looks like it works a lot better and there’s still room to fit the batteries and a switch inside of this
minty enclosure
.

[Mpark’s]
propeller controlled Etch-a-Sketch
is well built and very accurate. He was inspired by the
Step-a-Sketch project
and he’s carried that design through to a stunning conclusion. The driver board was built around a Parallax Propeller P8X32A microcontroller. But this isn’t just a serial controller board for connecting the hardware to a PC running CNC software. He’s included TV out and a keyboard port so that programming can be done on the chip itself.
In the video after the break you can see how precise the plotting is on the Etch-a-Sketch. It is well mounted but also benefits from some software compensation for the toy’s imprecise controls. [Mpark] has also included an erase function that tilts the frame upside-down a few times. This is used not only to erase a drawing but to hide the line created when moving the stylus into its starting position.

Like all great things, they must come to an end. As such, at 10am PST, this morning – our N900 Push competition came to a close. We had some really awesome answers, some really round about, and of course the obligatory – really bad ones. For those that are just on the EDGE of your seat waiting for the final concluding answer to stop the arguing and fighting – to settle this whole dispute. The answer, and the winners are…After the break.
Just to recap, the question –
You’re working with any one of the team winners in the PUSH N900 competition. Your team needs two like resistors in order to complete the project on time.
Luckily your work drawer is overflowing with resistors, and you know that there are only 4 different values since you pulled them yourself from old junk.
You close your eyes and reach in. What is the minimum amount of resistors you have to pull out to ensure 2 of the same value?
The Correct answer is
5
resistors.
[Talin Salway]
,
[Sari Ibrahim]
,
[James R. Smoot]
,
[Jody Halyk]
, and
[Thomas Remmert]
all sent in the correct answer, were picked by us, and gracefully pass their tickets to another winner. In the end
[Robrecht Noens]
was the only one to respond within our 24 hour limit claiming tickets. Congratulations, and hope you have fun at the N900 PUSH Showcase [Robrecht]!
For all those that sadly, did not win. You can still keep up on the party, [Matt] let us know…
We’ll be updating our
@PUSHN900
Twitter account regularly using the #PUSHN900 hashtag to help follow what you guys are saying.
We’ll be uploading video using
Qik.com/PUSHN900
Keep checking the
PUSH N900 Facebook
page for updates as well.
And finally an explanation: The entire riddle (as a lot of readers repeated to us in the entries) is based on the
Pigeonhole Principle
. In the worst case scenario, you reach in and pull out 4 different values. Thus, you must pull out 5 to ensure at least 2 match.

The Mechanical Diode

[
"Misc Hacks"

"rectifier"

A diode allows current to travel in only one direction. With that in mind, [Alex]
built a mechanical diode
that will only allow gear rotation in one direction to be transmitted through the system. But wait, by connecting two of these devices together he’s built something of a mechanical rectifier. An electrical
rectifier
converts alternating current to direct current and this mechanical version outputs clockwise rotation no matter what direction of rotation is coming into the device.
There’s video which we’ve embedded after the break as well as many pictures on his site but not much explanation. Here’s what we’ve deduced. The two large gears are inputs. Mounted on top of them is a smaller ratcheting gear that will only turn in one direction. This ratcheting gear selects whether the smallest gear on the left or right will rotate, which then feeds the output gear at the top of this image.

Each gear has a ratcheting system in opposite directions, the drill is the input to the differential, the outputs are connected to both. The gear with a ratchet preventing rotation will have a very high mechanical resistance compared to the gear moving in the direction of the ratchet, causing the energy to be almost entirely transmitted to the “correct” side.Then again, I didn’t think to build this and put it up on YouTube, so he certainly deserves credit.",

Yesterday we mentioned the
Woot! sale
of the Didj, and we had some comments and emails from readers who had purchased one. We couldn’t resist either, and ordered a couple to take apart and modify. We will probably be following the work laid out by [
Claude Schwarz
], who seems to be one of the leading hackers on the scene. [Claude] has done some work in porting the GP2x libraries to the Didj, which gives a tremendous head start to anyone looking to have a working game system any time soon. There will also be a
build log
for everyone to follow along at home, and contribute what you want and have, as well as a follow up How-To when a working system is attained. Happy Hacking, everyone.

Update: Adafruit Eagle Library, Now With Arduino

Adafruit Industries has
just added an Arduino shield footprint
to their EagleCAD library. If you don’t know, the
Arduino headers use non-standard pin spacing
. Learn to deal with it, there’s too many Arduino shields in production to have any hope for a change in the future. This footprint should make it a lot easier to design your own boards. If you use this package make sure you’re getting the library from their github,
they’ve been adding parts regularly
. Setting up
version control
will make sure you always have the latest libraries.
[Thanks pt]
