what about for that red one you suggested to me? what should I do there?
Thanks! So what should I do since the diode is case negative? can I just solder the negative diode wire and the case wire together for the LD I on the diode driver? or do I just not use it at all.I made a very similar build to this for my first laser. There's a link in my signature if you want an ideal of how to go about it. Definitely a nice little laser with basic burning. Also good for optical trapping.
I used a linear driver set to 378mA and that got me 230mW with the acrylic lens it comes with.
For a decent case that's relatively cheap, check harbor freight. They have aluminum cases with foam padding that are better than nothing.
Good luck!
Yours has three wires? I've gotten four of those from DTR and all only have two.
If it does have 3, I don't think you need the third (white one). You should be ok just cutting it, but I'm not 100% sure. I've had other diodes with wired case pins that could be ignored. If if it's still the same diode that I have, you don't need it.
Should no one else confirm this, pm DTR on here, he'll let you know.
As for upgrading, shouldn't be a problem. Just swap diode and driver.
EDIT: also if you upgrade a copper heatsink would be better than slapping a 1W diode in that little aluminum sink.
