This is the next piece of work after step 2 that dealt with the ringing bells, and now it’s time to look into the headset and how we can connect this to the new brain of the phone.

Rotary Dial Revival


I know it’s been a long time since my last post, but hey, at least I have an excuse…Β  he’s 2 and a half and knows no rest or the meaning of the phrase “staying still” πŸ™‚

This is (hopefully) only the 1st part of a series, based around this ’70s Rotary Dial Phone from Eastern Europe. I inherited it from my grandad when he passed away a couple of years ago. This is the same phone that I remember from when I was a kid and would play with at my grandparents’ house… ok, ok, I’ll stop here with the nostalgia πŸ™‚

So I can personally confirm it’s at least 35 years old, but probably more like 40 or 50. Most importantly it has quite a sentimental value for me, which means I have to be careful what I do with it !

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…

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 !

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™‚ )

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.

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.

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.
