hi moritz and group
i have some questions about other options of safety :
1. we build opto couplers ourself - using twoboards with tx led and rx photodiode . because inside of the box is dark no
need for any modulation(typicaly fm) and we just them as optocoupler ) .the minus is that box is dark - so you can't see what happens and if something breaks -youcan't see.
2.see thought box - 2 circuits and some kind of simple infra red modulation .
this more complicated then other option but clear box gives some little safety advantage , maybe ?
so what do you think ? are there better ,simpler options?
is one of themcould be in the 50ppl version? in the 10 ppl version ?
sincerly
yaniv
