Pet (work in progress)

I have not built my first robot yet - waiting for the parts. But I have the plans for my second robot ready. He, just a little ambition :D.  My second project will be a prototype for a robot that can be sold as a consumer robot. I will call it Pet - working title.

This is how I imagine it. When you order Pet, it will come in a nicely designed box. In that box you will find a shiny sphere, a little smaller than a soccer ball. One size of the ball will be flat. You will also find a smaller box that contains a base plate with an electrical cable. No on/off switch. No manual.

Simple servo bracket

Birdmun an Hi jinx got me looking into open scad, he is code a bracket for a servo you can adjust just by playing with a few numbers, the software is free and there's some tutoreals on line and youtube, you can export STL's as well. I did not think I would like it but after playing with it, my mind is more open, for simple shapes it is very fast.

Capturing Data from 7-Segment Display

Something I've wanted to do for a while is to be able to digitize the data from cheap sensors with a 7-segment display.

I decided to give it a try with some USB charge meters.

I purchased four of these meters.

I opened up one of the blue ones and probed the pins to see how the 7-segments were wired.
