Self Balancing Robot – V4

It’s been almost 4 years since I started playing with self balancing robots posting about the very first version, then the 2nd really unsuccessful one and finally a really jittery / impossible to control 3rd version…

Now it’s finally time to show you something that actually works !

It’s long been since I gave up any pretense of usefulness for my projects / hacks… now all my projects are “art installations”… (except when it’s something for my 5 year old son, which is always a good pretext to play around with some electronics… 🙂 )

FPGA : RC Servo and Stepper motor control in Verilog

It’s been a while since my last post … 8 months more exactly, which is probably one of the biggest gap in recent years… Having 2 kids is taking its toll on my hobby ! 🙂

A couple of months ago I did a tricky soldering job for a friend, to fix the wire / jack of his hi-fi ear phones, and I almost made a post about it… and then I realised, “hold on, is this how lame I have become, blogging about something as trivial as tricky tiny wire soldering ?”.

So here is something slightly more interesting, that I managed to work on this past week-end: my first foray into FPGAs !
