The circuit I'm trying to make is very similar to a laser tripwire circuit but with a few exceptions that I'm having trouble with.
I need a circuit with 12v DC power from a wall wart then regulated to supply 3V 10mW laser pointers that emit lines rather than dots. Each laser line will shine on 4 sensors simultaneously (I’m thinking either L14F1, PDB-C142, or any better option that will handle some ambient light fluctuations and still function for the sensors) that will activate a 6W 12V solenoid when any sensor is tripped (not receiving laser light) and have bi-color green/red LEDs on each of the sensors to indicate which sensor is tripped (red when tripped). That's the main idea of each circuit.
Then I need additional circuits that connect via daisy chain to the first/main circuit with 3 wires carrying power, ground, and a third wire that feeds back to the first circuit and activates the same solenoid if any of its 4 sensors are tripped. Each board/circuit should control one 10mW laser line and 4 sensors. The idea is that each board can monitor a level plane and if any of the laser fields (or flat planes) is tripped then the small 6 watt 12V solenoid will activate until the plane is no longer crossed.
I would like the ability to add additional identical circuits/boards (each with 1 laser, 4 sensors and 4 bi-color LEDs) by daisy chaining them together up to a total of 6. This will enable the entire device to monitor up to 6 flat planes.
So far for each circuit I have a LM317, LM339, (maybe a LM324?) a trim-pot to adjust sensitivity and to help with ambient light interference, 4 phototransistors (sensors), 1 10mW laser line, a BUZ101S, and various capacitors and resistors. I’m not sure if it’s better to regulate the voltage for all the lasers on the main board then send it to the other possible 6 or regulate the 12V down to 3V on each board.
