DIY Thermal Camera
Joseph Feb 21,2024
Ditch X-ray vision, thermal cameras are the real industrial superheroes! They don't just see light, they see heat, making them masters of uncovering hidden energy drains, pinpointing overheating gadgets, and even aiding soldiers in the dark. They're invaluable in industries like tech repair, where they sniff out shorted circuits like electronic bloodhounds. The only catch? Their price tag can be a bit frosty. But hey, technology is always evolving, and soon, thermal vision might be just as commo...

Retro Internet Radio using ESP32 & Transparent OLED Display | Back PCB
Rane Feb 19,2024
This project contains two different PCBs (Front & Back) with different designs. This page includes Gerber files for only Back PCB. Click here for Front PCBIntroductionSeveral years ago, I crafted an FM radio using the compact RDA5807M module, a tuner that delivered FM radio in a small package. While it functioned well and brought enjoyment to the entire family, the reception was subpar. I resorted to hanging a lengthy wire down my window to enhance reception just to get a usable audio on fe...
