I need something that can activate and hold a relay as long as an axle is rotating (don't care about speed and direction)
I thought about an optofork and a raster disc (from a mouse wheel). This would create a pulse train which can not be used to activate the relay, but can I put a "reservoir" capacitor over the pulse train to hold the relay?
Please help.
