Default driver in parallel?

is it ok to run two rkcstr, or even flex drives in parallel with the batteries? not sure how this would affect voltage or current.

I'd like to make a pink lasers......so i'm curious.

Default Re: driver in parallel?

I've tried it using 2 LM317M drivers in parallel, worked fine.

Default Re: driver in parallel?

I'm not positive about these drivers in specific but, any driver I've ever used can be safely wired in parallel. If your talking about making a magenta (pink) laser and you are trying to power two drivers for seperate diodes off of one battery, then simply wire the input of the drivers in parallel (pos. of batt to pos. of each driver, and neg. of batt to neg. of both drivers).

You can double the max regulated amps out at a given voltage by using two drivers wiring the inputs in parallel (same battery or seperate) and the outputs in parallel as well.

By wiring the inputs of two drivers to seperate batteries and the outputs in series you effectively double the voltage with the max amps out equal to the max of one of the drivers alone.

now i jsut need to get the cube to combine the beams, and get something made thats small, and is made hold the cube and the two aixiz modules.

Default Re: driver in parallel?

I believe the rkcster and LM317 drivers can be BECAUSE they are linear drivers. Something like a flexdrive with buck/boost would not work.

You can use the one out of a phr sled. Just file away until you can break away that section of the sled and get someone like misterwilling to make you some adapters like rog's white laser build.
