This is my project for laser pointer used dual diode 9mm, 26650 host. Using two diodes 9mm with copper heatsink and glass lens for 445nm. Testing + heatsink about 500mW/diode. The cube. Driver module with heatsink Button with Eagle Eye Led Green. Finish. Eagle switch. Front...

Thanks Jerry :D I don't have anyone Laser Safety Glasses :(

Thanks, :beer: I made by mysell 100%. But host i buy :evil: :beer: Ther driver is buck, 1840mA, M140 diode :beer: It made by me. :beer: Thanks, :beer:

This is my Blue laser pointer 2W/ 5 mode. http://www.youtube.com/watch?v=NdFZ4j0b5Pw

For this test, I am very assured in the test implant stability of the driver, running at different power levels.With the run load testing high currents (> 3A).Promote heat dissipation capability when running long test load is not too hot.I am very pleased with this achievement.

Thank lasersbee, This is the final finishing.Resistor 1 Om/5W not make me happy when you want to check one driver in the long run.It runs quite hot due to the heat sink, and I had to replace the 5W to 10W at the same time put it on the radiator, very good meet all requirements.

This my testload

I want to buy one 9mm laser diode 445nm blue. Pls help. Thankso much.

I can not order anything from any o-like dish, although it can successfully register your account. Does anyone have the status as me? Please help me. thank you

Yes, it work well. If use for 445nm, have 1300mA max, use for 12X, have 650mA. :thanks: Very good.

Exactly. When I use 4 x 1n4007 to check the output for my diod 445nm, if the current is 1A, then Vf is 4.5 V, but increased when the current 1800mA, VF is also increased by over 5.2 V . This is not understood.

I still use it for my diode 445, and it is working normally. however, I suggest using the battery should be protected, so it would be better for the battery power supply, input voltage representative of the lower driver, referred to battery depletion will easily cause damaged battery or battery...

If using 3x 1n4007 are not feasible, since its voltage output corresponding VF IR diode only when testing the first test load VF 2, up only about 3.8 V supply only, not suitable for 445 diode or 12X.

I use the test load, 4x1n4007 diode, so there really is good? I have read through a tutorial on NJG-18 circuit, which uses silicon diode 4x1n4007. So compared to 4x1n4007 and 6x1n4007, which enable better. When I test with 4x1n4007, VF is measured as 4.6 V 1170mA, but when using 6x1n4007, VF...

OMG :bowdown:

It is easy to use. When you buy it, will have two wires soldered available corresponding wire rope + and -. The surface of the bottom board has two inputs, respectively, + and -. If so leave the wire - and the top line - bottom, you can open the top of the line by DC is 350mA, and has three...

It works well, now I have about 15pcs, are used for both the PHR-803T, 12X and 445nm diode. I am currently using it for my diode PHR-803T, has three working modes.

Problem does not force you to charge money for drivers, but because it meets my requirements is to use only one battery. If using other drivers run in two battery, it too often. :D

Ok :evil: AK-007 0.8~1.5V 3-Mode Circuit Board for Flashlights (11.9mm) - Free Shipping - DealExtreme

I bought 3pcs from DX. However, when purchased may be used by extreme left - of the circuit below, only two are available and the anode of the battery is usable. if the user is always positive - of the circuit below, the only 350mA current and have more independent institutional use.
