It's been a while since I've made a laser and I got a good idea for a DIY green laser. But I need a little help.
I'm thinking about using this module :
Rayfoss
Is it good?
And also I need some 3V rechargeable batteries, 14500 AA size, but all I'm finding are 3.7V batteries. Can I use a LM317 chip to lower the voltage?
Thanks in advance.
