Hello. I have made a simple unit to start with. Consisting of a 445nm diode and powered by a 2.3 amp X-Drive V6. The battery is a Tenergy 3.7v/250ma. 20c Li-Polymer. Also shown is the beam combining prism I intend to use on the next step. I know this is simple and crude compared with what I have seen on this forum, but I want to go slow and carefully and follow all the protocols. Here are some pictures of the unit. Thank you for looking. Ed.
