Hello guys, i have found this on the internet: Music LED Light Box


I want to do this but instead of leds i will put lasers ! i am going to make 3 of those circuits, one for 2 lasers because i want o use 9V battery and the o-like drivers want 4-5V so every driver will have 4,5 volts. Now i have a question which cables am i going to connect to the sound circuit ? The TTL or the power ? And this is the driver: 2pcs Constant current laser diode driver 80-500mA w/TTL [OLDD20] - $5.00 : Welcome to O-Like.com, Your source for laser products

This didn't need a new thread. Stop spamming. I didn't reply to your PM's because I was hoping you might go try to find out some information for yourself.

Basically, you don't know enough on your own to do this yet. Spare yourself some expense, read up, and build it in a month or two. You can probably do something cooler then.

How old are you?

Did you checked the website for the music led box ? I am going to do the same but instead of 4 leds and a 12v battery i will use 2 lasers and a 9v battery !!! I have tested the circuit with the TIP31 and it works great with some spare leds that i have ! Then the lasers will light up with the beat of the music !

Yes I checked it.

A 9V battery isn't going to be able to support 2 445nm lasers... if it will at all, it won't for very long.

If this were me, I'd wire the modules in parallel on a 5V supply. Then I'd use 5V TTL modulation from an Arduino to control the lasers.

This design assumes that loud spikes in the music will correspond to the beat. If it does not, the light will look out-of-sync and distracting. If your music lacks spikes, the light will merely flicker.

You should learn more before you try to do this project.
