Ah yes, I remember from lab, you'd get a fail open right after you managed to manufacture a temporarily light emitting diode from things that are not normally light emitting diodes (or maybe not even diodes).
- bsder 9y agoWe call those "Light Emitting Resistors". They result when you attempt to violate Ohm's Law. You can generally diagnose those olfactorily as well as visually. :)

- lathiat 9y agoNow if only you could capture the smoke and get it back inside the chip. It would work again!
- MisterTea 9y ago> exercise Ohm's Law. FTFY ;-)
- phyzome 9y agoOr alternatively, SEDs (smoke emitting diodes).
- tyingq 9y agoOld bad electrolytic capacitors often smell like bad fish. Not sure why.
- Yetanfou 9y agoThere was this guy called Edison who once made quite a healthy business out of selling LERs. They seem to have lost some of their sheen nowadays but I suspect they'll make a come-back one day in miniaturised form, something like 'nano-LERs'.
