Re: Compact 1.6W Hotlights 18500 Host W/Driver Heatsink Mod Thank you for the advice. I'll try a heatsink for v5.

Re: Compact 1.6W Hotlights 18500 Host W/Driver Heatsink Mod Hi. DTR. Awesome laser! So legit! I have 2 questions: 1. In the current setting of your microflex v5, is there any difference between removing the end resistor and not removing as your v5? 2. Is there any delayed flickering? I...

Hi. Welcome to the forum. Probably "500mW-808nm-LD pumped DPSS green laser".:crackup: I think 100mW green.....

Hi. andyf97. Beautiful diode..! SHIN(@PL, @LPF), KOREA, 1 diode Thank you. SHIN

It is hard time to wait for v6... Hi. Drlava. When will I see v5 or v6?

Hi. larry. Welcome to LPF. Red laser diodes in DVD burner are mostly 2 types: open, closed. Closed can diode has a can covering dye crystal including AR(anti-reflection) window glass. Open can doesn't have a covering. You made a nice laser, but that cannot be collimated because there is no...

Re: SF-BW512L 12x BR sled GB *NOW TAKING PAYMENTS* :paypal: Thank you.

Re: SF-BW512L 12x BR sled GB *NOW TAKING PAYMENTS* Hi. qumefox. Can I buy one if still in stock? SHIN

Re: Group Buy for LPC-815, SF-AW210, PHR-803T, and GBW-H10L - Cheap! Hi, styropyro. 5 LPC-815 sleds, international(Korea) Thank you.

Hi. Morgan. When will the 2nd GB be open? Let me in. SHIN

Re: Dual driver Skyray Wow! awesome. You did it..:drool:

case-positive. except 780nm(= red pinout = case-negative) SHIN

Re: 3 mode driver for 445nm I think this driver is the only one that can power up 1W 445nm with ONE Li-ion in DX and KD AFAIK. Some fixation may be needed as the following picture. SHIN

Re: 3 mode driver for 445nm Hi. Pontiacg5 and RA_pierce There is no pulsation at fast moving of low-med-high all that mode. I expected the low mode were not visible, but visible.(I'm happy!) I used 4x1n5404 and 1ohm resistor. I wondered my test load calculation was not correct at low current...

Re: 3 mode driver for 445nm @3zuli I searched CPF but it is hard to find. I'll keep trying continuously. IIRC, there was something about change of sense resistor and formula something... SHIN edit)@wannaburn. AFAIK input voltage of amc7135 is max 6-7 V, not 8V.

Re: 3 mode driver for 445nm Hi. wannaburn. I also tested with several 7135 based drivers. But those were not for one Li-ion, but two Li-ion batteries. The current of 16340 is about 800mA, so I think two 18650s are needed for stable 445nm LD. SHIN

Re: 3 mode driver for 445nm Thank you. goninanbl00d. And thank you. 3zuli. My laser is for one Li-ion. Because I heard two mixed batteries "may" cause explosion. I'm a coward.:yh: With one Li-ion battery, maximum current is 1200mA. SHIN edit) I heard some CPF members "MOD" this driver to...

Hi.:yh: No laser driver around has "modes" as far as I know. I'd like to build my laser with modes. I have tested several LED drivers for 445nm LD from cheap sites as DealExtreme, KaiDomain. And I found a proper 445nm LD driver for one Li-ion...

Hi. AJ_Dual. I have built my high current test load, and I think this simulates LD more precisely. I hope this may be helpful for you.. http://laserpointerforums.com/f51/dummy-load-high-current-2a-test-load-3a-52372.html SHIN

You can cut the amc7135 driver into rectangular shape. (especially 2x amc7135) I built 500mW 5.6mm 808nm LD in aixiz with 2x amc7135 rectangular board and woked fine. I think it is possible that 2 of rectangular boards(each has 2x amc7135) can be containable. Microflex or rkcstr is common in...
