If neither of the 3 terms in the title mean anything to you, then you can stop here, there won’t be any nice video or images in this post:)

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:)

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 finish this ball balancing project, but after some improvements I started to get frustrated by the fact that the servos kept being “jittery”.

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

Double Servo Tester with Display


This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”…

The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a standard RC servo or ESC or anything else that uses the same control protocol.

Ball Balancing


 

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

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 !

Optical Wheel Encoder from Infrared Printer Sensor


Quick post about some intermediary work I had to do while working on my new Self Balancing robot.

Once the basics were done and the robot was balancing, I realised that it seemed unstable as it wasn’t staying in place…

The easiest way to deal with this would be an optical encoder for the wheels, that would tell me how much each moves.

Home improvements


Some of you will be surprised by this post, as it has nothing to do with what I usually blog about… still this is the main reason why I haven’t done any electronics projects lately, in spite of having some free time…

So here are a few pictures of my more “traditional” projects that I have been doing lately, it feels good to do some more manual/dirty work, rather than just soldering and programming:)
