Having read the following thread, I thought it better to start a new thread, rather than start old arguments . https://forum.allaboutcircuits.com/threads/converting-square-wave-to-dc-voltage.122935/
I have a requirement to power a <300mA camera from each vehicle indicator signal. To make it more awkward, the flasher unit is before the indicator switch, therefore the signal (left or right) is, I believe, ostensibly a square wave. Without loading the circuit too much (it will effect the flashing rate), can I connect a bridge rectifier across the bulb circuit to provide 12v DC to power the camera? Because this is for a road/race car, size, weight and complexity is at a premium. I would like as simple a solution as possible, as switching the camera on and off at the same rate as the indicators, is not very effective .
Can you assist and give any guidance?
I have looked at Arduino options, but it gets bulky very quickly.
