If I want to power seven 20x dvd laser diodes just using one 9.6volt power drill battery...amps(? maybe 4-5 amps) would I install a momentary switch to activate the circuit on and off ,and wire the diodes with a longer wires from the bread board wired in "paralell" so the voltage stays the same 9.6 volts and set the current on the drivers for 450ma each? Would the drivers each still get enough current to work at that setting or would they start to drop off? Also just curious can a 20x dvd red long open can laser diode survive straight off a 9 volt regular battery for short pulses for maximum power with 5-10 second burn times and about 30 seconds off? I realize that a driver would be best but just how many milliamps does a small 9 volt battery have anyway...say an "energizer" brand? Has any ever survived being straight wired with no driver for such short burn times?
