Hi, im about to build a 4-motor spirograph, and I always wondered something. If I point the beam on a 45 degree angled mirror, and the beam gets reflected by 90 degrees, will the circle produced by the mirror not be distorted on the wall?? Regards Pascal

Can blue diodes be that cheap? Hi Powered Blue Laser Diode 150mW I'll post a datasheet of the diode later when I've received it I wrote an email to this guy. Greetz

Hellooo I took up my work on lasers again after a long break...I've tried to get my phr's working again but it doesnt work either. Configuration is: -9 Volt battery, fully charged -rckstr driver set to 100mA with Testdummy It didnt work...dont know the problem, thats the question. But I...

Helllllloo, I've just received my phr-803t diodes and a sony 16x red dvd burner diode, with aixiz modules and rckstr driver! I have a problem with the test load I also ordered, I don't know how to use it...so I'm thinking about not to use it and connect the 803t straight to the driver, set the...

:wave: Hello, this is my first post on this forum and I'm starting with building my DIY lasers :bowdown: I have a physics problem about lasers, perhaps something that I don't understand. The driver of a laser regulates the electric flow (miliampere) that is given to the diode. And nobody...
