My PS3 slim refused to read blu-ray anymore, I’ve ordered a KEM-450AAA laser lens, just replaced it and it worked ! PS3 is working again ! #ps3 #retrogaming #repair

I‘m trying to build an ultrasonic levitation device following https://www.youtube.com/watch?v=B4pIJwy_ySY but I found weird to connect +5 V to ground here. What do you think ?

Thanks to https://t.co/3U3hEYabjc & https://t.co/HO1TauEGhB 🙏, I was able to install RaspberryPi OS (Debian 11) on an old Surface RT (Win 8.1 with IE11 😱 & no more update). Linux is awesome to give second life to old devices ! #Surface #RasbperryPiOs #linux #hardware

Was able to recover my first Z80-MBC2 board by de-soldering/resoldering new resistor networks in correct polarity 🎉. Now I have 2 boards, one with IOS « full » (with sdcard and RTC modules) and one with IOS Lite. Time to have fun with CP/M 😀

Second attempt to build a Z80-MBC2 is a success ! I think resistor network on my first board are reversed. #z80 #retrocomputing

Ok, got temperatures from an Oregon Scientific sensor with an Arduino Uno using a RF 433 Mhz module and that excellent library https://github.com/Erriez/ErriezOregonTHN128
Next step, replace the Arduino by an ESP32 ! #previousTweet #hack #electronic #RF #arduino

Bonjour @Parisjecoute,
Bravo pour la campagne de sensibilisation des déchets à l'école mais pourquoi diable offrir une mini-poubelle en plastique aux enfants ? Mes enfants ne jouent pas avec et elle finira... à la poubelle ! Je trouve cela contre-productif. #écologie #déchets
