This is the 2nd part of a multi post series about bringing back to life an old rotary dial phone.

After managing to interface with the dial itself in part 1  it’s now time to do something about the vintage, bells based, ringing mechanism.

Rotary Dial Revival


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

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 🙂

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 !

Custom Remote WiFi Mains Socket Switch


Here’s again one of these small hacks that I’ve been wanting to do for a while but never found the time…

There’s actually not that much to it, the most interesting part is probably just being amazed at how easy it is nowadays to pull off this kind of hack…

Receipts Printer Photo Booth


As soon as I finished my previous project, I knew I could improve it…
With pictures, of course ! And also take them on the fly, like in a photo booth…
Why use Haskell to generate pictures on the printer ? Just because Functors, Applicatives and Monads are obscurely cool… 🙂

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. …

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… 🙂 )

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.
