a framework for PIC based USB devices
under Windows. It includes the firmware needed for USB compatible 18F PIC chips as well as a C# class library and example programs for the Windows side of things. This goes quite a bit further than
his PIC-USB tutorial
but with little added effort on your end of things.
We do our USB prototyping on a breadboard just like [Simon] did in this example. He’s got a nice little USB-B connector breakout that is easy to plug into the breadboard. If you prefer to have a more stable development area, check out
the one he designed
. It’s a single-sided PCB made for through-hole components with just a handful of jumper wires. | 11 | 10 | [

Seven speeds and a reverse gear were built into the gearbox
for this LEGO vehicle. It’s not completely an original design, but adds to the five-speed design found in
a ten-year-old LEGO set
. See it demonstrated in the video after the break. The design uses a
sequential gearbox
; shifting is accomplished by clicking the stick up or down depending on how you want to shift. If you’ve got enough parts on hand you can build this using the
assembly photos
that [Sheepo] posted.

If you build it, heed his advice on testing with a pair of cheap headphones before you risk plugging in your prized pair.

"animatronic",
"giraffe",

"maker faire",
"makerfaire",
"robot",
"servo",
"walking"
] | If you’ve had the opportunity to attend the annual Bay Area Maker Faire, you’ve likely encountered
Russell the Electric Giraffe
. Modeled after a small Tamiya walking toy scaled up to the height of an actual giraffe, Russell was created by [Lindsay Lawlor] in 2005 originally as an “art car” providing a better vantage point from which to enjoy the
Burning Man
arts festival. In the intervening five years, the Electric Giraffe has enjoyed face time in dozens of parades, trade shows, magazines and television appearances.
Scattered about [Lawlor’s] living room floor at the moment are the giraffe’s dismantled steel skull and several massive Torxis
servos
(the red boxes in the photo above) — Russell is being upgraded. One of [Lawlor’s] goals in returning to
Maker Faire
each year is that he not simply present the same exhibit time and time again; the robot is continually evolving. Initially it was little more than a framework and drivetrain, and had to be steered by bodily shoving the entire 1,700 pound beast. Improvements to the steering and power train followed, along with a “skin” of hundreds of
addressable LEDs
, cosmetic improvements such as a new paint job, and technological upgrades like interactivity,
radio control
and speech. His goal this year is to bring expressive
animatronic
movement to the giraffe’s head and jaw, hence the servos, push rods and custom-machined bits currently strewn through his living space-cum-laboratory.
[Lawlor], 46, is a lifelong “maker,” with a gamut of talents from electronics to optics to mechanical engineering. Aside from creating this giant walking machine, he restores
motorcycles
, installs high-rise fire safety systems and has built his own
laser
light show projectors. And perhaps surprisingly, he’s managed all this without a degree or other formal education, just an intense curiosity and unstoppable drive. We posed to him one of the most common questions we receive at
Ask HackADay
, as to how one can get started in electronics and building the sorts of
creative projects
regularly featured on Hack a Day:
Don’t be afraid of failure, it’s a crucial part of the learning process. Get your hands dirty and start building projects that interest you — build a model airplane, restore a motorcycle. By tearing it apart and putting it back together, you learn to see what makes it tick. Someone who’s brave enough or sometimes lucky enough to acquire the means to build something, they end up with a vast amount of practical knowledge about what they’re interested in. Textbooks alone can’t provide that.
Seek a lot of advice from people who’ve worked on this stuff before. Respect them by following through…don’t just talk about your grand plans. Go to Burning Man or Maker Faire or hang out with artistic people. This will bring crazy ideas to the forefront. The amount of influence you receive from showing up at a place like that is incredible. It’s unstoppable, a really powerful force.
Maker Faire is just a few weeks away. [Lindz] ponders the explosion of parts on his
workbench
and floor, uneasy about the looming deadline. Can he pull it off and complete these upgrades in time? We’re firming up plans to attend the show and hope to provide our readers with updates of all the various displays, including Russell and — fingers crossed — his new face. | 10 | 10 | [

A bit light on the details, but we enjoyed seeing this
video out device for the Nintendo Game Boy

[NeX] mentions that he originally wanted a screen to be included in the cassette. We’ve seen custom
portables with small screens
before, but he’s also developed
a bare bones hand-held without a screen
so that’s where the inclusion in the cassette would have been handy. We also wonder how the images will look on a big TV of the 50+ inch size. [NeX] has been pretty busy with the hacking lately, don’t miss the

This method saves him from leaving his computer running. It parses the text data from the public transportation website and updates both an LED display, as well as a Twitter feed.

water-based amusement
before and this did originally start out with a water cannon powered by a wind-shield washer reservoir.
Take a look at the videos after the break as well as
his recent post
for information about the hardware. His choices for controller circuitry are way overpowered, sourcing an Eee PC to do the heavy lifting. This is because the choices he made were for easy development and not economy of components. A PC has no problem connecting to Xbox 360 controllers, and the modular control boards mean no complicated circuit design or arduous soldering were necessary. In the end, this looks like a ton of fun and we give him bonus points for repainting the pretty pink plastic that comes standard with these models of children’s toys.

Here’s
a solenoid motor you can build from a VCR head
and some common components. It uses an LED and a light sensor, paired with an LM311 comparator to manage the switching of the motor. As the head turns, the LED shines on the sensor through a hole and triggers a TIP120 transistor to turn on the motor during the power stroke. Once the beam of light is broken, the transistor turns off the motor and the momentum carries it through its revolution until the next power stroke is activated.
We often say that “why” is the wrong question. [Bd5940] must feel the same way because he ends the video by saying: “it has no use, but definitely a conversation piece”. Yep,
we’ve seen that before

introduction to rapid prototyping class at Cornell University
. See his description of the project after the break.
When he shared the link with us he mentioned that this might be a fun project for beginners and we couldn’t agree more. The design is easy to wrap your mind around using the provided
schematic
. The source code package includes PDF files that contain well commented code segments along with their descriptions. You can use this to get comfortable with driving a speaker and servo motor using an Arduino, as well as to read from two different types of inputs. We are especially interested in the hardware debounce implemented for the switch that detects if the lid is closed. Software debouncing is pretty much the standard these days but because an external interrupt is used to read the switch that method won’t work here.
If you’ve got an Arduino and few of these components why not give this a try?

contest-winning Internet radio player
.His finished board is roughly the same size as the 16×2 character display and piggy-backs the device for a small form-factor. It can be controlled via an infrared remote control, or through a remote web interface. Source files are available from the link at the top, but the really juicy details are included in the shockingly comprehensive
PDF writeup
.
The photo above is a bit misleading. The board has a micro SD slot on the back even though a USB card reader is shown. This project would need
USB host control for Propeller chips
in order to use that reader. Don’t forget to check out some of
the other submissions to the the contest
once you’ve had your fill of this one.

Project J.A.R.V.I.S.
is an attempt to create a digital life assistant, or DLA. The name comes from the version in the movie Iron Man. While the details of the build are pretty slim, you can see that he’s using a mac mini for the base with an Arduino controlled RFID reader at his door. What is really interesting is how functional he has actually made it. Watch

a teletype machine and hacked it to monitor Twitter

turns something into a teletype

The Arduino in turn formats the message into the serial format necessary to communicate with the device. To the left you can see a trend plotter, learn more about both in the video after the break.

A hopper stores a row of golf balls. When it comes time to load, a ball falls into the chamber, starter fuel is sprayed into the combustion area with the aid of a fan, and after both chambers are sealed the propellant is ignited.
We’ve embedded two videos below for your amusement. It looks like [Chrille] and his friends are being careful with their creation. We’re glad for that because this is about as dangerous as the

something we didn’t expect

The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.
What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might
we suggest processing

However, in the opposite respect, more components than ever are being epoxied to the board, making the iPad much more rugged.

The comments have made it very clear how dangerous to you and others using this cable can be. The image above is not of a full male-to-male cable, only the ground is connected, and the generator is not running.
We all know Ethernet has the crossover cable, cars have jumper cables, and RS232 has the null modem. Well, it is about time our wall sockets get their own crossover cable. This crossover cable is great for running power to a circuit disconnected from power. Maybe you are out of fuses, the breaker is broken or you just don’t want to go check the fuse box when there is a murderer about. This cable makes a great gift for even the most loathsome of acquaintances.
This an April Fools’ Day post. You should not do this!!!
Warning: These are Mains voltages and currents we are working with. If you do not know why you should not attempt this, you should not attempt this.
You will need:
1 Extension cord.
1 Male extension cord repair connector.
Tools to strip the extension cord, and attach the connector: Knife, wire strippers, and screwdriver.
Respect for mains voltages and currents.
If your extension cord has warning labels, read them.
Cut the extension cord to the desired length.
Strip about one inch (2.5cm) of the outer insulation from the part of the cord that has the male plug.
Strip about 3/8 inch (1cm) of each of the conductors. If there is a strip gauge, use it for a guide instead. Twist each of the stranded conductors to prevent fraying and possible shorts later.
Slide the shroud over the cord.
Screw the conductors into each of their respective terminals on the connector.
The Green or bare conductor goes to the ground conductor terminal. It often has a green screw.
The White conductor goes to the grounded conductor terminal. It often has a silver-colored screw.
The Black conductor goes to the ungrounded conductor terminal. It often has a gold-colored screw.
Use a multimeter to check continuity and make sure there are no shorts.
Slide the shroud up to the connector and fasten the two parts together.
Secure the cable clamp.
There you have it, a finished Mains crossover cable.
There you have it, a Mains crossover cable. How might you use this crossover cable? | 397 | 50 | [

Get a quick fix of CNC for the day with

The optical head assembly from a cd-rom provides the Z-axis movement with the whole thing controlled by three RepRap boards. [Francisco] called his project a joke compared to
the Turing Machine
, but we like it and we’re glad he
tipped us off
. There’s something zen-like about the projects that are thrown together with what you have available. After all, he’s certainly achieve a clean-looking build that does what it’s intended to do. | 23 | 23 | [

"hypervisor",

] | Sony is rolling out a
firmware update for the PS3 on April 1
but we’re pretty sure it’s not a joke. What we’re not sure about is that you can call it an update. It removes features rather than fixing or adding them. In this case, it is removing the “Install Other OS” option that allows you to run Linux on non-slim versions of the PlayStation 3. It is fairly obvious that this is a reaction to the hypervisor exploit that was released back in January that breaks down the machine’s security barriers.
[Geohot], the guy who found and release the exploit,
published a post on his blog
expressing his disapproval of Sony’s actions. We’d have to agree. It’s pretty cold-hearted to remove functionality that was advertised with a product. We’re sure there are many folks out there using the Linux support who have no interest in exploiting the product. This is gardening with a backhoe and quite frankly it stinks.
This may bring on a torrent of
new effort in unlocking
and laying bare the PS3. If so, doesn’t Sony deserve it?

just became quite a bit easier
. When
we originally looked at this hack
it required pulling some capacitors off of the board. Now all it takes is three commands over a serial terminal connection.
Take a look at the walk through video after the break. You’ll see that there’s one chip that needs to be setup differently to change the functionality. Removing capacitors was actually changing the commands sent to initialize that chip at power-up. Now you can just change the model number and one letter of the serial number via a terminal and the firmware will recognize this as the more expensive DS1102E.

They’re achieving accuracies in the 82-97% range but it gets even better. Take a look at the video after the break and see what they’ve done by adding a pico-projector to the arm band in order to use your arm or hand as a touch display.

a precision chop saw
don’t overlook the value of adding a diamond blade to a spinning HDD platter. [Tony’s] four-part writeup of this build springs out of some very special design considerations for a ham radio that operates in the 47 GHz band. That frequency pretty much rules out using normal components in the circuit and in his case it even makes connecting the components together difficult. He’s using this chop saw to cut small pieces of a ceramic substrate with gold traces on them that will be used to route the signals on the circuit.
We’ve seen hard drives used in
a couple
of
different clocks

a set of speakers

The hardware design is ingenious; one servo rotates the egg, another is mounted on one side of the egg and moves a track in an arc so that a felt-tipped pen will follow the curve of the shell. The pen moves in an out along that track through the use of a third servo physically removed by a
Bowden cable

FIRST
, For Inspiration and Recognition of Science and Technology, competition congrats
you’ve won one internet
.
This past Thursday, Friday, and Saturday (March 25-27 respectively) the Oklahoma FIRST regional competition took place. Once again I, HaD writer [Jakob] was lucky enough to not only attend, but compete! Check out our full breakdown after the jump.
Readers may remember some time back when we explained he
OKBEST competition
, and noticed it had striking similarities to the FIRST competition. While the build time is only 6 weeks for both competitions, that is where the similarities end. We would love to give a rehash and an explanation of differences, but readers might like to simply read and compare for themselves between BEST and FIRST and realize they are completely different games.
This years goal for FIRST, is in short, a soccer game. A field with 6 robots (1 robot per team), three blue, three red, battle it out head to head; blocking, scoring, and more to be the winner of the round. The addition of not knowing your two other teammates until the day of the match, and the inclusion of small ‘hill’s and ‘climbs’ increase the difficulty of the competition. Those looking for a full explanation of the rules and game type can find it
here
.
Team captain once again played the role to allow me to bring you this overview. Unlike previous robotic competitions, this was the first time our team, 3124, attended FIRST — making us rookies.
Our team’s design, if put into one word would be
simple
. The initial aluminum frame was constructed on kickoff day from our kit of parts. After that, to keep the soccer ball out from under the robot – we wrapped a (donated supply) wooden skirt around the perimeter of the bot. A pneumatic (donated, yet later not used, we broke too many rules with it) kicker was implemented. After having traction issues – a custom spring suspension system (perhaps the most complicated portion of our robot, two springs and a bolt) kept all 4 wheels securely on the ground.
While we were rookies, had very little funding, only two/three active members, and even more disadvantages we still managed to come out on top. By ranking 5th (out of 54 other teams) in the seeding rounds, we attended semi finals after asking teams 932 and 2842 to join us, and ended up 3rd overall; giving us the award for Highest Rookie Seed. Anyone wishing to watch some (or all) of the matches and learn how teams ranked up should check
BotsnLinux.net
.
First definitely is a unique experience, and I’m glad I was able to attend. Honestly, we didn’t expect to reach nearly as high as we did in rankings. But thus teaching, you don’t have to have tons of money, or a complicated system, or a large team, or the best design to win. The adventure of course taught us much more than that in the end as well. Hopefully values and ideas that can be taken and used in future endeavors for years and years to come. | 37 | 37 | [

pretty impressed by this robot build
(
translated
) though. We’re not totally clear on who actually did this build, but we can see a few pictures and a video on the site. The original doll looks to be roughly 3 or 4 inches tall, judging by the Eeepc keyboard that it is standing on. We counted 7 servos stuffed into this thing with a controller board hiding in the back of its hair. You’ll have to watch the video to see most of the details. It looks like there is one in the head, one in each shoulder, both hip joints, and both feet. Though the motion at the end of the video is limited, we still think it is impressive. Creepy, but impressive.
note: the video is not embedded in the translated version. Just go to the non translated to watch it.

We may be good at soldering but when it comes to hauling topsoil our scrawny arms quiver. [Johndavid400] did the smart thing here by
letting the machine do all the work
. Instead of hauling an entire truckload of dirt across the yard one wheelbarrow at a time, he built a shelf on the top of
his Lawnbot400
. We saw this lawnmower Arduino-powered, remote control mower back in November. The addition of its ability to handle some of the manual labor makes it the perfect backyard hack.

The device is made to interface with the MakerBot and includes a thermister for temperature sensing. With a small firmware upgrade you can now set the build stage temperature which should make larger printed objects a bit easier to deal with. A while back we saw
a hotbed for the RepRap

replace a disposable coin cell battery with a capacitor

He’s mounted one on his milling machine but noticed that with an external power supply the readings would sometimes reset in the middle of his work. The LR44 cell he’s replacing makes for very difficult in-place soldering so instead of permanently replacing it he built an insert that matched the form factor. The outer ring is from a piece of copper tubing and soldered to a PCB that he etched.
If [David’s] name sounds familiar it’s because we featured his

"darlington",
"LPT",
"printer port"

printer port (LPT) adapter
. They wanted an indicator light when someone in an IRC room was talking to them. By connecting a blue rotating light through a relay to the output of this fob they’ve done just that, but there’s room for much more.
The adapter uses a
Darlington transistor
array IC to protect the computer. A resistor between the LPT and the base pin on the chip ensures that current flow will be well within the safe levels for the computer. The Darlington transistor amplifies the output using an external power supply in order to drive heavier loads.
If you want a deeper understanding of the printer port
check out this tutorial
. LPT ports are becoming less common and that’s why so many projects are migrating over to USB (plus there’s no need for external power with most USB connected projects) but if you’ve got one, it’s probably not being used for anything else. | 28 | 28 | [

floppy-disc augmented reality display
a few paragraphs down that caught our attention. He’s taken 36 white floppy discs, sprayed one side black, then mounted them each with a center pivot into a 6×6 grid. Through a convoluted system of pulleys and servo motors the display can be manipulated to produce
augmented reality markers
. After the break you can see the display itself, then the result of viewing it through a webcam.
We’re amused, but also scratching our heads. There must be an easier way, such as
a light-up grid
covered in dark plexi or something along those lines. But then again, it’s his hack and he can do what he wants… and
he seems to have a thing for floppies
.

developing a method of killing mosquitoes with lasers
. The system is called a Photonic Fence and identifies the beasties by the frequency of their wing flapping (hey, that’s exactly how we know when they’re dive-bombing our heads). Once locked-on, it’s death to the filthy blood-suckers.
This story was latched onto by the gambit of news sources in the middle of 2009. Since then, the development team has added some pretty interesting info on their webpage. Last Feburary several videos of mosquito flight were posted. These were shot at 6000 fps using specially designed photographic rigs (probably
much like this one
) to make sure the shots were in focus. Now they’re
slated to give a talk at the 2010 TED conference
. The publication of these talks sometimes lags behind by several months so be patient. Watch the video after the break to get some abstract shots of the hardware being used; they’re not giving up the goods until the conference.

Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.
You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

Being hackers, sometimes we just want to hack something together, not engineer it. This
projector is a great example
. Made mostly out of cardboard and duct tape (
or duck tape if you prefer
). He picked up a 12v LED array, a cheap fresnel lens, an LCD from a “back up monitor” and a focusing lens taken from a magnifying glass. Sure,
we’ve seen better
, much better. But seeing an evenings worth of feverish wire twisting and taping is always pleasant. It may look pretty dim in the video, it may be as well, but keep in mind that it is common for them to appear much brighter in person or if shot with a night setting on a digital camera. | 21 | 21 | [

They have also designed and tested a homebrew cartridge with a slot for a microSD card and breakouts for expansion and debugging.
Right now they are looking for someone with experience snooping USB protocols to figure out how the device communicates to the computer, as well as anyone who is interesting in just testing or playing around with what they have done so far. There are a number of tutorials and walk-throughs on the
eLinux wiki

Graffiti Machine
that he built, which we’ll look at in-depth after the break.. This isn’t the first CNC machine he’s worked on. [Ben] became interested in rapid prototyping but was put off by the cost of commercial cutters, which led him to build his own
CNC plasma cutter
.
[youtube=http://www.youtube.com/watch?v=5uFsZEqCBV4]
[Ben’s] creation consists of a vertical gantry that houses the motors as well as a carriage for the spray paint ‘rattle can’. He’s using stepper motors and belts to move the carriage and gantry with a controller that he picked up from
HobbyCNC
. Let’s look at how he put it all together.
This is the can carriage. On the right, above the can, you can see the motor used to start and stop the flow of paint. To the left you can see the timing belt used to move the carriage up and down. Its ends are secured with C-clamps.
[Ben] uses the head of a machine screw to depress the valve of the rattle can.
The top of the gantry houses motors to move the gantry itself as well as the can carriage.
The full gantry is one piece with the can carriage traveling along its length. You can see the timing belt that the gears use to move the can.
The two images above show the belts used to move the gantry along the top and bottom horizontal tracks. A rod travels the length of the gantry, driven by a stepper motor on one end to move the gears of both the top and bottom belts.
This image shows the angle-bracket that is used as a track. This gives the machine horizontal scalability.
This closeup shows a skateboard wheel with a slot cut in it. This keeps the gantry firmly seated in the track as it moves.
[Ben] ties the system together with a Linux box running the
Enhanced Machine Controller
. He’s hoping to pit man against machine some day in a graffiti showdown. This is a great build [Ben], thanks for sharing the details with us. | 18 | 18 | [

, he set out to detail the particulars when it comes to using the PIC 18F family as USB input devices. This example uses a PIC 18F4550 with the circuit built on a breadboard. There’s not much required here, an oscillator, a few passives, and a USB B connector. The magic really happens in the code. Take a look at this well-written guide and give it a try with your next project.
Don’t need USB? [Simon’s] game hack,

"Ask Hackaday"
] | A while back,
we announced that we would be bringing new features to Hackaday
. One in particular that garnished a lot of interest was our question answer type thingy. Well, in case you hadn’t noticed, that has not happened yet. Without divulging too much into the secret machinery that lies underneath Hackaday, I’ll just say that we(the writers) don’t necessarily have control over all aspects of the site. An example would be the copyright. Yes, we finally got it updated. Thanks for all of your emails. No, none of us had access to that part of the site, so don’t bother letting us know how simple that change should have been.
We are as eager as you to see some good ideas and good feedback flowing through this site, so we’re going to start a regular post, entitled “Ask Hackaday”. This isn’t entirely new, we’ve
done it before
actually. This is just to let you know that we intend to do it regularly, and to set some ground rules. “Ask Hackaday” will mostly center around you, our readers, and your ideas. We will publish a question, and possibly our thoughts, but the main content will be your responses. We have a huge collective of intelligent creative readers and it would be a shame not to tap into that pool of knowledge. When you are offering an answer, be thorough, give details, and please be kind.
Send your questions to askHAD@hackaday.com for consideration. They will be chosen based on a complicated system of random number variation involving furry woodland creatures and how we feel at the moment that we read them. Do not get offended if you question does not get published. We get tons of questions already and we don’t intend to publish them all. | 32 | 31 | [

[XenonJon] got a lot of attention for a skateboard/segway style balancing platform he took to the Makerfaire in Newcastle. He decided to try to
build it the cheapest and easiest possible way
in an attempt to help others build their own. The build is documented very well, however you have to email him to request the code for the Arduino. Maybe after enough requests, he’ll just pop it online. We thought this looked familiar, so we searched the archive and found
this very similar setup
from back in 2005. Unfortunately, that project page appears to be gone now. | 20 | 20 | [

"clock hacks"

"acrylic",
"clock",
"POV"
] | This gorgeous
persistence of vision clock
was built a couple years back by [mb1988]. The housing is made of acrylic with a hard drive motor mounted in the center of the back panel to spin a PCB. The two-sided circuit board is home-made and includes a battery for power, ATmega32 for the brain, 32 LEDs, four display drivers, and a real time clock module. The spinning hard drive motor is nearly silent and already has threaded mounting holes on it. [mb1988] uses an optoelectric sensor to sync the display with the rate of rotation. The forum post includes download for the code and hardware details. Don’t miss the demonstration after the break.

"HackIt"
] | [
"OK Go",
"rube goldberg",
"Syyn Labs"
] | We’ve received many tips regarding the OK Go video that features a Rube Goldberg machine. If you haven’t seen it yet,
check out their video
after the break. This is the rare instance when a YouTube video features an audio track with the full endorsement of the artists that recorded it.
Our first thought when watching this? Who are the lucky dogs who got paid to design and build that contraption? You don’t have to scratch your head over that one, the Band has posted a four-part video series talking about the machine and documenting the design meetings and build process (those videos also after the break). The engineer artists at
Syyn Labs
were tapped to pull off the meticulous mayhem and we think they did a stellar job. There’s been a lot of press about the work, but
our favorite was over at Wired
because it details the process, not the end product.
The best part about Rube Goldberg Machines is that asking “why?” is the wrong questions. The sheer joy of the build makes
taking over a house
or
over-complicating the fulfillment of hunger
worth it.

"Robots Hacks"
] | [
"RoBo Blower",
"snow blower"
] | Snow removal ranks right up there with laundry as one of the least-enjoyed chores. [Herb Spencer] sought to automate the process while terrifying his neighbors as the same time by building a robotic snow blower,
the RoBo Blower
. The heavy lifting is still handled by a gas motor which propels the snow auger. Two batteries power the electrical system that takes commands from a remote control, moving the show chute and managing the navigation. He’s done what he can in the way of safety, adding a grate at the front, flashing light atop, an operator-controlled horn, and kill circuitry (to shut it down, not to kill the unsuspecting). All of this is wrapped up in a nice package, especially when compared to the
snow blower push platform
from last month.
Maybe next year he’ll work on making it
autonomous
? Take a look at the RoBo Blower clearing a driveway after the break.

built it using parts from a Roomba
. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this
Rocker-bogie suspension
. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of
the Roomba’s
rough-and-tumble outdoor cousin.

[Daniel] wrote in to show us the project his group has been working on. It is a massive display wall consisting of 28 projectors and 30 computers. With a resolution of 7168×3072, viewing a 13.3 gigapixel image is a treat. That treat is made even stronger by the fact that navigating the image is done multitouch style with a touchless system built from web cams. We’ve seen lots of projects come out of the
NUI group
with similar interfaces, but none that used the webcams like this. Usually, the webcam is detecting some kind of interaction between the person and an infra red light source. Maybe that is happening here and we just don’t see it. | 23 | 23 | [
