Thermal Printer Remotely Controlled through an ESP32


Again one of these things that I’ve been wanting to do for a long time, but never found the time to… having one of these little thermal printers that spit out your receipt at the till in a supermarket, and hack it to print little snippets of information like reminders or shopping lists, etc. …

Simple Radio Controlled Car


There’s nothing much to say about this, no micro-controller or programming or any fancy stuff involved… it’s just that I’ve always wanted to build a simple RC car for my kids…

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 !

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… ๐Ÿ™‚ )

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 ๐Ÿ™‚

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.
