In this video i repair a xiegu x6100 transceiver bought from ebay.It was advertised as defective and indeed had no rx/tx. But this was an easy fix ;)

Just out of curiosity : can somebody identify this ?

i had this inexpensive chinese power meter on my small solar system for about a year before it start failing. Now the screen flashes at startup and nothing more... Let's try to repair it !

This nice radio, a Tykho by Lexon, has developped a trouble : it won't charge its battery anymore.I decided to try to save it. I found the inexpensive ltc4054 chip on Aliexpress. ( As well as the horrific fake "kapton" tape ). Hope it will help to save some other ones !

In this one i make a "springbit" to remove solder mask from homemade pcb on the cnc. It was a bit difficult to find the right settings to make it work but the result is ok.

Has i installed a new bathroom vanity from ikea, i encountered a problem with the depth of the upper drawer that was blocked by the pipes behind. As i was not willing to re-work the pipes, i decided to reduce the drawer. Here is how i did it.

In this one i experiment with making a diy discone antenna. It is probably not a great one, althougth its performances are better than my old groundplane. Many parts are temporary parts : pla isolators... and it is clearly not waterproof... but as a proof of concept, i consider it a success !

Some esp32 dev boards are quitte annoying to use on a breadboard. They are too wide. Here is an adapter to use them with two breadboards side by side. I could have done that much faster with a perfboard... but where is the fun ?

I found inexpensive sockets for Lego NXT / EV3 on Aliexpress. Thought it coud be fun to hack lego mindstorm bricks a bit. So i made a quick and simple adapter for breadbording it. No real project so far. Just for fun. Sockets on Aliexpress : fr.aliexpress.com/item/1005001891427575.html
