Hello everyone,
i'm new here and wanted to ask a question about making the same laser as styropyro in this video:

but i don't know how he powers 3 different drivers with one power supply, can anyone help me with this?



(this is my first post, and i hope to post a lot more and to learn many things about lasers)

He clearly says in the video he uses a single cheap 12VDC output, AC wall adaptor for a thrift shop to power all 3 and how he arranges that with 3 LM317 drivers and 3 pots.

That video is from 2013 before cheap RGB modules were available on ebay. Just buy a RGB module for $60 on ebay to see how they work. https://www.ebay.com/sch/i.html?_fr...esc=0&_osacat=0&_odkw=RGB+white+laser+modules

Nobody on LPF is going to babysit you through attempting to copy/make what's in that 2013 video. Ask Styropyro if he will/can give you a parts list and instructions.
