Good combination?

Hello wanna ask about violet laser if i buy and build is it will be good ?From ebay:

405nm 5 6mm Laser Diode Host ?12MMX30MM Aluminum Host w H Heatsink and Glasslens | eBay
1pcs Pak Brand New 405nm 410nm 100mW TO18 5 6mm Sony Laser Diode Violet Laser | eBay
405nm Laser Diode Driver 3 5 5V CC Circuit 2pcs Package | eBay

Not really, but the good thing is that you asked the question at the right place. If the objective is to make a violet laser that does 100mW(ish) you have a better chance of getting close to that with a ebay pen ($5 usually)

You can also contact thejoker301 or go to Sci-Fi Lasers (thejoker301) it is a member owned shop and they sell some amazing products for very great price, Im sure he will guide to towards a better beginner option that suits your taste.

But if you must build one, and really want to go the DIY route then go right ahead :beer: Hope this helps!
