I built my IR laser with the cheap LED driver. IR LD is can-positive and Vf is about 2V. So this amc7135 driver is a good match. 3 or 4 of amc7135(300-350mA) with one Li-ion battery will work fine. SHIN

Hi. Pontiacq5. I have built several AW210s with this driver. Upto 250mA with 3.0V - 4.2V battery. And read this for the right lead connection: http://laserpointerforums.com/f52/review-o-like-blu-ray-driver-53372.html SHIN

Thank you for the diagram. BShanahan14rulz. I tested with my custom 2A/3A test load and it seemed to work fine. 445nm LDs are on its way. I'll post the picture if this is successful. Again I appreciate you. SHIN

Hi. BShanahan14rulz. Thank you.;) I'll try like this: 445nmLD===7135driver---1n54xx-1n54xx-1n54xx-----Li-ion--Li-ion-----tail switch <---------------- P60 module -------------------> <---battery---> My P60 heatsinks were made after surefire-compatible P60. (nailbender@CPF, dealextreme etc)...

Hi. I built a few of 445nm with v5, microboost. But maximum current of v5 to 445nm is 1.2A and microboost is 1.1A. So I am looking for high current driver. I have my custom P60 heatsink already, so I can use round circuit board for LED...

Thank you for the great work! IgorT. Your graphs are textbooks for me.:wave: And the explanation on test load is COOL. I experienced two of 1.2W 445nm of 850mA v5. Finally I built my high current test load. http://laserpointerforums.com/f51/dummy-load-high-current-2a-test-load-3a-52372.html...

I post a PDF data file of 1N54xx. I hope the voltage-current graph (Fig.3) will be helpful for accurate calculating the drop-out voltage with 1N54xx. 1.1-1.2A --- 0.8V 2A --- 0.85V 3A --- 0.9V

Thanks. HIMNL9. I would like to burn my test load if there are 3A drivers and 3A laser diodes. :D SHIN

You're welcome.:)

My specialty is way from electronics, too. One day, I tried to set v5 with 445nm LD at over 1.2A but could not set over 1.2A. I asked drlava about this and he replied so. And this is described (as a equation) at last lines of drlava's v5 manual. I'm waiting drlava's "v6" that could kill 445nm...

Hi. bhank.:yh: Maximum forward current of 1N53xx is 1.5A. Voltage drop of 1N53xx is 0.9V at 1A. To set 1.1A with 445nm LD(4.1-4.2V), [V-drop at diodes 0.9 x 4] + [V-drop at resistor 1.1 x 1] = 4.7V I think roughly 3 or 4 of 1N53xx is needed.:thinking: Drlava's microflex v5 can supply maximum...

Hi. HIMNL9. Nice work for high current test load.;) And I like heatsink. At high current as 2A, is there more voltage-drop at test load diodes more than 0.7V? Like 0.8V to 1.0V. SHIN

:crackup: ......................... :(:yabbem:

Thank you. iknitsreel. I built my AW210 after you.:yh: SHIN

This one(10440) is slighly longer than previous 1xAAA one, and is thinner than ordinary pen(2x AAA). Power seems stable. SHIN

Thank you. electron.

Hi. I received 5 of my 405/445 lenses today. I wonder if all 5 are "red" glass lenses. 4 of lenses are purple-tinged, one is light blue-tinged. Will I return these??:( SHIN

I tried once with 1W 980nm. For invisible long distance communication. But high power IR LDs were all multi mode and difficult to focus.
