Hello everybody. I havent been around much lately but Ive got a lot more time on my hands now (summer break) so Ive been checking out the forum again and seeing whats new. Anyways I was thinking about all these driver designs I have on my computer that arent being used and Im sure some of you...

Hey guys! I bought a transformer on ebay for $25 and free shipping. It arrived with $27 and change due! I didnt pay it, just left it at the post office for now. I think if I went ahead and paid that would mean I accept the charge and cant do anything about it. Now from my understanding it...

Sup guys, got another open source driver here! When the pl520 green diodes came out I had an idea to make a driver for them. I had saw a chip that could run from as little as 0.8v and still boost high enough for a blueray or green diode. How cool would it be to run your laser from either a AA...

Hey guys, rhd's magic board and IRON4D driver will be at cajun lasers very soon so I am writing a little tutorial of how to use them. First up is the magic board. For those of you who dont know, this is a small circuit rhd made that allows you to put your battery in backwards and the laser (or...

How would you like free boost driver designs?! :drool: Though I can't control anyone's actions, I would appreciate it if anyone wishing to sell this circuit would get permission from rhd or me first. This is a project that I have been working on with RHD for a pretty long time and it is...

I found some 20mw 635nm diodes on eBay! I know recently there has been some buzz on these higher than 5mw 635 diodes, and I have been watching around trying to snag some. Unfortunately it is a ten pack and I only want one, maybe two. Cost is $175 buy it now for 10 diodes. I am unsure if more...

Ive been pondering an idea for a cool laser but I need to get a question answered before I start building. If I have a small (30mah) lipo battery can I charge it from a 5v supply by simply using voltage dividers to get 4.2 volts, ~30ma and timing the charge? Or do I need to uses special...

So I bought one of o-likes newer style 405nm driver , the one that does up the 250ma, and can't get it to work. Ive made some phi pointers using the old style driver and it works fine ... But this new one didn't do so well. I hooked it to a test load and then to a standard 2x AA battery pack...

I need to know if it is safe to put two li-ion or li-po batteries in parallel. I have heard that if you want to do this you need to use a special circuit to keep them from discharging into eachother. If this is true where can i find one? I have searched around and have no results. What are...

This thread is to continue our discussion about plzting zinc on copper in serac's thread about his copper host. I decided to start a new one because I felt like i would be thread jacking him if we continued to talk there. Seracs thread...

This is my first thread so i suppose i should introduce myself, i am Ben Martin and i live in wv. I have done quite a few diy lasers and am soon to have a 445 (it is in transit). My lasers are : 10mw blu-ray pen, ~150mw blu-ray torch, 200mw 532nm pen (est. about 170mw), 30mw 532nm labby, 1...
