But here's my problem. The camera has a resolution of 640x480 pixels, which produces a noticeably blurry image when displayed on my 24" monitor (maybe I'm just not blind enough yet, ha ha). Considering that the system sells for a retail price of about $2300, I would've expected better resolution than 640x480. |
Interestingly, I see that consumer grade HD camcorders with a resolution of 1024x720 are readily available at Best Buy for under $200. This started me thinking about how I might be able to make my own high resolution CCTV. I figure there are basically four components: the software to display the image, the stand to hol... |
The software component is not an issue. I'm a professional software developer and can slap this together easily. For the stand, there should be some kind of off the shelf solution. I don't think I would need to make my own. The camcorder can also easily be purchased off the shelf. This leaves the optics as the last com... |
It seems like I ought to be able to do this for a total out of pocket cost under $500, and the real cost would be my own time spent writing the software, debugging, and optimizing the system. |
So that's a summary of my limited thinking about this project so far. Has anyone attempted something like this? We're all programmers here, so maybe someone else has some ideas about how to make this work? Or am I nuts and I should just shell out the $2300? |

[mythtv-users] LiveTV isn't flexible enough about its inputs |

I'm pretty sure in 0.18.1 you have to explicitly change cards (and |
perhaps inputs) if a channel isn't available on the current. |
How exactly would I do that? After all, no matter which way the |
option is checked, it's basically up to Myth to choose which card is |
the one used when capturing input that's going to LiveTV. Is there |
some magic keystroke sequence that says, "Change to card number n, |
and now change to card n's input m" when in LiveTV? (And man, is that |
ever risky, because it requires someone using LiveTV to have an |
intimate knowledge of exactly which card(s) Myth is using [and |
planning to use] in order not to disrupt a recording.) Otherwise, |
the only way I see to do this is to put an extra input on my 350 |
and bring all composite inputs to that card, just 'cause it's the |
card being used for output, and that seems crazy. [Or is this what |
you actually meant, e.g., rearrange the hardware?] Architecturally, |
there seems to be no impediment grabbing input from any tuner and |
tossing it to any FE, and that would seem to apply for any input |
to any tuner. |
OTOH, I'd certainly believe it if there's some implementation |
limitation in 0.18.1 that makes this not work. In which case, |
I'll repeat my question: Does this sort of thing at least work |
in SVN? And is it truly an implementation restriction in 0.18.1, |
or is something misconfigured in my setup? |

COMPUTER MUSIC; Program Notes Explain It All |
Published: April 28, 1991 |
To the Editor: |
In discussing my composition "The Music Machine," performed at Carnegie Hall by Jorge Mester conducting the National Orchestral Association, Donal Henahan seemed bent on dismissing my work because of its specific programmatic premise: a machine or computer that composes music, thus the title [ "Paramusical Notions That... |
Yet Mr. Henahan jumped up and down on the computer angle instead of leveling with genuine criticism. With all due respect to the players involved, he might have mentioned that the performance was largely misrepresentative; that the orchestra, made up mostly of young students, had insufficient rehearsal time; that Carne... |
Instead we had the Henahan refrain: fear and ready-made hatred of computer music, atonality, serial music, electronics, etc. Perhaps he was also set off by the critical element in the music, which questions traditional symphonic gestures. There is apparently a lot going on out there that Mr. Henahan does not like in pr... |

Too Much Boat? |
Hello everyone, |
I'm in the process of researching before buying a boat to live aboard and single hand - probably in the Caribbean. I'm planning on doing this alone, at least to start, I'm 57 and have no family - and I don't have a lot of sailing experience. I'm going to the USVI in April to take an extensive Ocean Sailing and Navigati... |
I've posted questions here about rigging for single-handed sailing a 34-40 foot boat and got some excellent advice. |
I've also read a few other threads on this site about cruising. |
Up to now, I've identified the following 'needs'. |
1. I want to spend as little time in a slip as possible - preferring to try being 'on the hook', so storage of water, fuel, waste and basic living needs is important. I'm quite comfortable being on my own and don't want to blow the budget on slip fees. |
2. From what I've learned here and from my own research is that a cutter rig with furled 100% yankee headsail (to clear the mid-stay when tacking), self-tending furled staysail, gale sail that can be raised over the furled yankee, no furling on the main (unreliable), below deck autopilot (and wheel mounted autopilot ba... |
My budget is $80k - $100k for a used boat that would suit my needs - but I wouldn't mind spending less. So far I've been looking at the 20-30 year old Tayana and Hans Christian because of their large tankage, sturdiness and good below deck storage. Don't know if insurance would be an issue with older boats like these. |
Here's my question. |
Am I crazy? |
I don't want to spend tens of thousands every year on maintenance and repairs (I'm not currently all that knowledgeable about doing my own repairs), and I certainly don't want to get a boat that would prove too big for me to handle either at sea or when docking. I've read that 'smaller is better' for cruising, meaning ... |
Do I need to re-evaluate my criteria - and look for a smaller boat? |
Your advice and responses would be greatly appreciated... |
Zanshin 11-09-2009 11:14 AM |
If you intend on remaining in the Caribbean islands then your boat options go up, since you don't need a rock-solid bulletproof "bluewater" cruiser. While I don't have many of the financial constraints that others do, I think that bigger is better; there is a lot more space, storage and living, in a bigger boat, it ten... |
Ex-charter boats can be had for good prices in the USVI/BVI that will be more than enough for your intended use. |
Tanny 11-09-2009 12:03 PM |
Gorgeous boat! Unfortunately, my financial restraints require me to think a bit 'smaller'. |
I don't know about a used charter boat. Most of them are Beneteaus and their tankage capacities are tiny. Plus I just worry about the shape they're likely to be in after being used as bareboat charters. |
My reasons for a 'rock-solid bulletproof bluewater' boat are mainly tankage capacity and sturdiness - not bluewater capabilities. Maybe my criteria is unwise, but that's the reason for my original question regarding the state of my mental health. |
Do you live on your Jeanneau, or do you have a land base? What are your yearly maintenance costs? |

I was asked this at the Providence, RI event and didn't think it could be, but I did find this that works for SQL 70 and SQL 2000. I haven't really verified it but I'm sure it would work with SQL 2005 either as is or with some minor modification. |

I have a Toyota Camry LE V which has a... |
Dear Tom and Ray: |
I have a 1998 Toyota Camry LE V6 which has a couple of disappointing |
characteristics. I drive frequently in town at around 40 mph. While driving at |
that speed, it feels like the engine is constantly searching for the right gear. |
The only advice I've gotten from the dealer is to disengage the Overdrive while |
in the city. But, when I do that, the car almost feels like the emergency brake |
is on when I let my foot off the gas. Any advice? -- Tom |
RAY: Yes. Listen to your dealer. You're driving the car right at the speed at |
which it shifts between Third gear and Overdrive (Fourth gear). In automotive |
parlance, the transmission is "hunting." If you crawled under the car, you'd |
probably see it dressed up in one of those orange safety vests. |
TOM: The only way to eliminate the hunting is to either change your driving (not |
drive at 40 mph in the city), which would probably be very inconvenient, or shift |
out of Overdrive and force the car to stay in Third gear. |
RAY: And while taking it out of Overdrive does eliminate the hunting, you do |
experience a little more "engine braking." Personally, I think it's hardly |
noticeable at 40 mph, but you're obviously a sensitive driver and it bothers you. |
TOM: Neither engine braking nor hunting will do your car any harm, Tom. It's |
really just a question of preference, Tom. Which one do you find less annoying? |
RAY: That's a question our readers and radio listeners ask themselves about US |
all the time! |
