  • The company I work for makes a product which goes into weapons like missiles, planes, jets, helicopters which are used by Israel and realizing that it was probably going to go towards helping kill innocent civilians. I mean technically we are sub sub sub contractors, but they are used explicitly for this project and purpose

    My only consolation is that I stopped working on those ones personally after a week of “Make it work but dont change ANYTHING”, they constantly fail testing and are sent back for RMA, and the guy they hired to fix them is so criminally incompetent that the company has had to completely revise their hiring proces

    Unfortunately with exactly 0 responses to my applications in the last year, I probably won’t be jumping ship to somewhere that pays well and doesnt have me as part of the MIC
















  • Dimmers will typically use a triac which cuts up the sinusoidal waveform. It doesnt actually lower the amplitude per se, but it limits the fraction of the time the waveform is on. Kinda like this. This means that a lot of the time the led isnt gettingas much or any power. The average power will be lower, and if the LED driving circuitry isnt designed to compensate for this, the LED will flicker.

    Clarification on triacs: they get turned on a certain fraction of the way into the cycle. Triacs will stay on until the voltage across them is 0. Conveniently the zero-crossing of the AC wave (when the wall voltage crosses zero to start foing negative or from negative to positive) does just that.
