HOW TO – Breadboard breakout for leadless chips

HOW TO – Breadboard breakout for leadless chips

Here’s an interesting strategy for accessing the tiny pin contacts on no-lead QFN chips using temperature resistant tape and a conductive pen. Starlino’s example intentionally bridges several pins but theoretically should work for accessing all of them individually (considerable patience required, of course) – Reverse Surface Mounting of small leadless SMD components [via Curious Inventor]

It’s inner workings remain a bit of a mystery as its maker only specifies it being an analog/digital hybrid with feedback circuitry … and a whole lotta banana jacks. Well no matter what’s inside it looks quite killer. Visit Skot’s site […]

Chinese farmer’s walking creations

Chinese farmer’s walking creations

National Geographic interviews Wu Yulu, a chinese farmer obsessed with building walking machines. Wu was ridiculed for a long time because of his mechanical creativity, but recently has gained recognition for his self-taught skills after being named China’s most innovative farmer. Over the years he’s managed to construct some pretty awesome automatons from salvaged materials. […]

Alternative MMC/SD connector hacks

Alternative MMC/SD connector hacks

Ralf Ackermann sent in this suggestion for soldering an alternate connector straight to an SD card for a cheaper way to use SD/MMC cards in an embedded project. Pictured is his ATMega based MIDI recorder/player that uses this design. This reminded me of another hack by Rob Wentworth. He noticed that the pin spacing on […]
