Honest question: is that a crap power tree because it's electrically unsound or because it exposes these attack channels? In the first case, it's really crap. In the second one, the extra cost (cents or dollars?) should be part of the the security risk evaluation made by the customer. Maybe that attack was an unknown unknown until now.
- Kirby64 3y agoElectrically unsound. Having a LED flicker enough purely because you're adding load to the device is just poor engineering. There should be enough decoupling on the LED supply so that it doesn't flicker visibly when another system nearby is loaded.
- NavinF 3y agoLEDs almost never have decoupling caps. I've literally never seen a design where there was more decoupling than the minimum necessary to stabilize the power supply's control loop
