stm32f4-discovery art


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… πŸ™‚ )

RC Car Electronics


This, to some extent, is a continuation of this post, where I replaced the motors and some gears to fix one of my son’s RC cars.

I remove the electronics and replace them completely, including the remote for which I now use a freshly made wireless Wii Nunchuck.

The results are far from impressive in terms of manoeuvrability, but it was really fun to build and I think the handling can still be improved by tweaking the mix between the 2 joystick axes.

Automotive CAN bus hacking


This 1st video shows the dashboard of a VW Passat B6 2006 being controlled directly by a micro-controller (an old ARM M3 on a LM3S8962 Texas Instruments discovery board) using the automotive CAN bus.

Hack a humidifier with an AtTiny


 

This is a refreshingly simple hack on which I spent only a few hours, most of which were actually for installing Atmel Studio to program the AtTiny πŸ™‚

Ball Balancing – V2


Same story here as with the last couple of posts: these are some rather old attempts at improving a previous project, without much success, even after a considerable amount of effort… Hence the decision to still create a post as a future reference.

Self Balancing Robot – V3


Same as the previous post, this is an old project that still doesn’t work properly, but will probably never have the time to fix, so I’ve decided to post the details here, in case I need to refer to them later.

Self Balancing Robot – V2


DSC06380

This is a quick post to dump some pictures and lessons learneth the hard way, when I tried to build a nicer / better self balancing robot.

All this dates back from October 2014, so more than 1 year ago, but I finally gave up on trying to make this work and wanted to keep all this info/details for my own reference.

Arduino, when the Servo library is not good enough…


 

I went back to try and finishΒ this ball balancing project, but after some improvements I started to get frustrated by the fact that the servos kept beingΒ “jittery”.

Time for my new and shiny servo tester I thought… ! It turned out I was seeing the same problem.

Ball Balancing


 

I know it’s been a while since my last post, but 2 kids and a new job take their toll πŸ™‚

Most importantly, for this past few months, I’ve been thinking of a way to say “thank you” to my former colleagues that somehow managed to offer me the absolute best leaving present: a Meccano kit and a prepaid Maplin card (this is the equivalent of the now defunct Radioshack, for my U.S. readers) !

Ex fellow markiteers, this post is for you, thank you for your present and more importantly thank you for having been such nice colleagues for almost 9 years !
