The G-Meter
Thought I'd just post up about a little project I started on Wednesday. I ordered an Baby Orangutan (AVR Atmega 168) and an 18G accelerometer not long before RoboWars 5. I finally managed to dig it out last week and start playing with it on my breadboard.
Anyway, I decided to tinker and started on the path of making a G-Meter, so I knocked it up on the breadboard and started playing.
Two videos here of G-Meter v1.0 - just a few LED's showing roughly some G force scale.

A video of v2.0, now with funky LCD screen

Still needs some more work to get it calibrated and to stop the glitches, but I'm happy with it. Almost gave up on it tonight when the LCD screen wouldn't show any text, after two hours, I found a forum post on Sparkfun suggesting to tie the Rs pin to ground, and it worked.....
Once I tweak it enough, I'll look at buying another accelerometer in the 3-5G range and made up a proper unit to mount into my Silvia Wank factor some would say, but I reckon it's more Geek factor _________________ https://www.halfdonethings.com/
