DIY transfert/etching PCBs at home
For a new project I am starting I needed to do DIY PCB using the transfert and etching method. I got a ~cheap laminator off amazon (a metal one, which was more expensive than an all-plastic but it seemed more rugged and probably more able to reach 200’C), a few litters of Ferric Chloride, cheap

Recreating the ARP 2600 synthesizer
I stumbled upon someone blog post who did reverse on the ARP 2600, made “corrected” schematics, and PCBs images to transfert/etch. From that I started the project of building an ARP 2600 and also making it a project more modern with KiCAD. The first step of getting the schematics captured is done, intensive reviews are

Here is a status of the projects I’ve been working on: MFJ-929 Auto Tuner: done Got this one a few years ago and it ended up on a corner. One IC seemed dead, a 5V reg was cooking, and the PIC16 too. Replaced the three, reprogrammed a new PIC16, and the unit seems to work

Summary: 2018 – Aug 2020
First thanks for all the patrons, some money seems to have been left over by Patreon and ended up making around ~150EUR, which I spent on a headbump for a second-hand 13MHz RACAL-DANA Programmable Frequency Generator last year. I wanted one for a long time to help doing repair on radio equipment, and my first

Elka Concorde 405 – Restoration project – 2018
Hello, As you can see in the picture, I now own this… thing. It is in poor condition, first because it’s “for parts”, old, and UPS dropped it on the ground because they are a really nice delivery service. The Elka makes sound, most of the LEDS doesn’t works, some (4-5) keys doesn’t works, two
