HI-DEF? Retrofit B&W TV! JPEG obsolete? (LOL!) DIY!

In the latest Nuts and Volts there was a statement that JPEG may become obsolete, and while that may be true, if all things must pass, but I don't see something called HD-photo from Microsoft replacing it. What would Mac and other computers use? Jpeg, because the web is full of Jpeg, and unless one ...

In other words:

STATE 0 --- 1 --- 2 --- 3
IN- 0101 0101 0101 0101
OUT 0100 0100 0101 0100

IN WAVE _/\_/\_/\_/\_/\_/\_/\_/\
OUT WAVE _/\___/\___/\_/\_/\__

Looks funny but might work.

My project was to help the police ticket OTHER people who tend to cause accidents, in the vicinity of the car, and do a small part to improve the safety of the car. Yours seems to be to wiretap your own driver "for safety and legal reasons". I'm not sure how I feel about that, except if you don't tr...

The silver-black screens with no backlights are STN , I think.
Those laptops are pre-pentium (386 or older) and probably really cheap on ebay.

Some of the older compact fluorescents actually have a small ballast coil and starter tube just like any other fluorescent. They're simpler and more reliable than what's in them now. (Yuck board with weird power supply.) I'm a fan of "cold cathodes", which to me seems to work more like neon signage,...

Microcontroller: Have a medium sized RAM memory buffer as a LOOP to sample into. Maybe enough to hold a one-second loop. 8K perhaps. 1.0/1.6 = 5/8 so after writing 8 samples from input, read one sample to output and then skip 5 samples on the reading pointer. (Do not skip writing any input samples, ...

The spy-on-cars cam .... someone asked me to design it, and I did, for the purpose of recording nuisance behavior and license plates and sending it to the police. Example: Every day someone I know sees someone crash while talking on a cell phone, which is illegal here. Unfortunately only the police ...

Put a tiny solar cell or photodiode on a plastic VU meter with a needle
that you might have found in an old tape deck, receiver, or battery tester.
Then touch it to the remote and push buttons, looking for the needle to wiggle.

Soldering golds? or brass?

I think brass tips exist, look like gold, and stay looking nice for a much longer time than others.

I'm surprised I couldn't find a Patent for an "ANY" key on PC keyboards.

But I found #7100312 ... "A Working Machine"
aka. Machine with a motor that does something useful.
Bill Gates pays no royalties because windows PCs definitely don't qualify.
