Filling the gaps

Went over to Micro Center after lunch in search of a video card, USB stick, and toner. Found 'em. For $40, $30, and $100 respectively.

The video card is a Radeon 9250 with 128MB of RAM; I can remember when that was a respectible amount of memory for a workstation. Plugged it in and it just plain worked, so I'm a happy bear. I have a quiet office again! Yay!

As it turned out, just pulling the old toner cartridge and rocking it gently from side to side restored it pretty well, but at the rate it was fading I'm not going to count on more than 100 more pages or so at the outside. So the new one won't be sitting around for too long.

I've determined that what I really want for a heart-rate monitor is a pulse sensor, preferably wrist-worn, that talks bluetooth. That and GPS drivers for my OpenMoko phone. A page or two of code can take it from there.

That would do the trick, wouldn't it.

Just out out of curiosity I searched a little, but didn't turn up much. Only this, http://www.blatand.net/brustgurt+M52087573ab0.html, which appears to be vapor.

It's such an obvious thing to do, I'm surprised no one really has yet.

I may have to consult our resident hardware hacker.

The other possibility would be to go in through the audio input -- it's low frequency, but that shouldn't be much of a problem unless the input's capacitor-coupled.
