What Actually Happens When You Leave an ESP32 Running 24/7

Heap fragmentation is the quiet one. It doesn’t crash immediately. It just reshapes what’s available. Allocations that worked on day one start failing in strange ways. Not clean failures either. Partial allocations. Corrupted data. Functions returning values that feel slightly off.

Replaced 20 of them on my PCBs. Would have been totally helpless without that giant magnifying glass on a goose neck at my table. #electronics

Flexible gel can turn body heat into power for next-generation wearables

A soft material developed by researchers at QUT can convert body heat into electricity, opening the door to self-powered wearable devices and more sustainable energy technologies. Published in Angewandte Chemie International Edition, the research found that the flexible hydrogel captured wasted heat and turned it into usable electrical power with record efficiency. The paper is titled "Ionic Coordination and Hierarchical Architecture Enable Record n-Type Thermoelectric Efficiency in Soft Hydrogels."

Dear Luxman,

please never ever make something like the LV-117 again.
Thanks from everyone who has to repair your amplifiers.

My effort to replace the four BS-170 transistors and to add protective zener diodes failed.

The microcontroller still works. Over USB it's possible to "screen /dev/ttyACM0" and get to the diagnostics, to trigger a test transmit into a 50 ohm load.

But no signal comes out.

Worse, even idle, the PA transistors and output transformer are hot. They shouldn't be!

Stare at schematic, thinking.

Might be time to write it up, bag it up, set it aside, buy replacement.
