It can be done

Hi All!

Just wanting to ask a quick question -

I have recently purchased this diode: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=220462816592&ssPageName=STRK:MEWNX:IT

I need a driver for it, would this work?

 http://cgi.ebay.com.au/104mA-constant-Current-driver-405nm-Blue-laser-diode_W0QQitemZ280385152413QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item414841e59d&_trksid=p3286.m63.l1177

I want to try and fit all of it into a torch fitting of some sort, hence i want to buy a small driver rather than a larger one - i could make one if someone posted schematics for a small one though?

any help would be appreciated!

If the seller of that laser diode is telling the truth about the output of that Blu-ray you will need a far higher output driver.

The LM317 driver on this site would do it well.  I suggest you go to laser pointer forums to get further info on the LD if you can post a photo of it it would help.
