That's What I'm SAYIN'! ;) With that part count, even if the circuit is from the datasheet and thus the same, 2 people won't independently come up with the exact same routing/placement. Perhaps it should be called the 'Fakestr' driver... cheers, kernelpanic

Hello All, For what it's worth(Which probably ain't much)- Current controlled drivers are a fairly well explored area of electronics. Most of us when designing circuits will use the reference implementation in the datasheet as a starting point. So that 2 different people came up with similar...

Mike, The LM1587 is a good choice as well. The circuit is identical to the DDL. It's available in SMT and TO-220 package. So for 2A you'd use a 3W, 0.62 Ohm resistor... (The entire driver costs about $5 to throw together.) cheers, kernelpanic

Jayrob, Received my host/heatsink today. (It actually came yesterday as I slept, signature required) As before, you've done a great job. Nice find on the host also. It's way more solid than the one bestofferbuy.com sent me... Anyway, thanks a ton! I'll post the build once it's finished...

You've got 12 posts, 0 rep and a 3 day old account. You'll be better off if you wait until people know you better before you offer trades... cheers, kernelpanic

Jayrob, Will do. Thanks again! Your timing is perfect. I should get the kit and the driver parts at around the same time... cheers, kernelpanic

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP Chris, Got my diodes today. You went above and beyond as usual. THANK YOU. Thanks also for the chocolate drop dum-dum as well!(My wife might like the sour-chewy pop. Personally it's not my thing...) cheers, kernelpanic ;-) p.s.- I'll be...

Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C Oh Man!!! I'm Jonezin' for my order... ;) (Drooling may be more accurate.) cheers, kernelpanic

Yeah, I saw that too. Looks very cool! (Another link - Here's the same story from 'Nature') http://www.nature.com/news/2009/090409/full/news.2009.360.html cheers, kernelpanic

Re: Tutorial - Easy MXDL 'Side Button' Laser Build Hello All, O.K. Bestofferbuy.com was a bait-n-switch. They sent me a different MXDL side button host. I'll post a pic later. It is a nice host and it looks like it would take a heatsink. But it's not what was advertised. (5387) It also does not...

Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C Miloš, It's my understanding that Chris bought all of Boston Lasers' inventory. He was able to answer all the questions I had and stated that specs would be included in the package. HTH, kernelpanic

Re: Tutorial - Easy MXDL 'Side Button' Laser Build Hello All, Looks like this host is available from bestofferbuy.- http://www.bestofferbuy.com/mxdl-1w-led-flashlight-black-3xaaa-p-14067.html They bait-and-switched me once before though. I've ordered two and will post back when I receive...

Re: Different kind of group buy? B_G - Beware of off-brand SDHC. Many of these cards were produced for branded sale but failed quality control. The rest were likely produced in factories without QC... cheers, kernelpanic

XaseR, It's true you want to limit the amount of heat you apply to the diode. However my experience is that the time taken to solder is more critical than the temperature of the iron. (I have actually burned out a diode trying to use a 15W iron because the time required to melt the solder was...

Re: phr-803 12$ and lpc-815 12.5$ READ FIRST POST Drew, Got mine yesterday. Everything perfect. Thanks again, kernelpanic
