I just got the test boards from the PC fab house. There was 1 surprise, but wasn't hard to figure out.
I'm trying to have some to show and sell in Carlyle this weekend.
It mounts in any piece of rolling stock you like. A magnet sensor goes on one of the trucks and the display goes any place you like. The thing is powered by 2 AAA batteries, which should run it in excess of 100 hours.
How far have you gone?
Altoids™ Oscilloscope
Posted by Tom on Nov 1, 2012
I've been using an "xProtoLab" from Gabotronics as my oscilloscope for some time. It's made to be plugged into a breadboard, but since I use smd devices, the breadboard was getting cumbersome. So I decided to put it in a case.
So I took an old-style Altoids™ tin with a flat lid, etched "Gallifreyan" writing into the lid, and
installed a little circuit board with a 5v boost converter to power it from 2 AAA batteries.
I have it on good authority that the Gallifreyan translates to "Mine! Keepa yous hands off!"
