Cigarette in video smokes like it burned by 100-150 mW laser

No. It is my homemade boost driver. I use same driver (at higher current) for my 445. I kill my 6x not long ago when I tried to extract it from Aizix module :( Thanks! :)

It is done in semi-finished style :) I think I'm lucky, as my 6x ran at 260 mA long time although other's diodes died at 180 mA very fast :)

Aixiz glass for 405 nm

Krogith, It working at 0.5A

I tried to cut the toothpick with my 12x, but I got the fire kiN08qebOtY

No. There are several laser forums in Russia and they do group buys like here. I get the 2 diodes from A130 at the price of only $43 for each Thanks :yh:

Yes, it works continuously about one hour without overheat!

I have created the thread right now: http://laserpointerforums.com/f65/1w-portable-445-laser-homemade-driver-images-video-57212.html#post808990 ;)

My portable build: working at my hands: The beam in the evening at sunset: The beam and the fog: The dot at 100m distance: my homemade boost driver (big inductor is at other side of board) the driver's electrical scheme: And some videos Construction and beam: q0PJNydYYCw Parer...

I did driver for 1.5A myself using TPS61030 chip :) The driver: and my laser with it:

My copper heatsink :) LD from A130 was placed in copper heatsink (see at photos) and works now at 1.3A The beam focused to infinity (not to small dot) burns carton (2 side) in 20 seconds Video at YouTube How I inserted aixiz module into heatsink :) Original heatsink: Heatsink improvement...

erdabyz, thanks for the advice!

I planned to use this driver with bright LED not LD. Now I plan to use more power chips for "driving" blue laser. Even 1A is not enough for me. I need minimum 1.3A :)

No. I have only photo of my driver :) (inductor is on other side of the board) It is too small and overheats very quickly at 1A :(

My first 445 is working at 0.75A driven by LTC3454 now :)

I don't have oscilloscope here so I can't show my diagram. But I trust the information from datasheet :)

Height of inductive spikes depends of type and capacity of output capacitor. 10 uF ceramic capacitor will smooth spikes very well. You can find oscilloscope screen images at fifth page of datasheet. Value of spikes doesn't exceed 20 millivolts with 0.5A current at the load. PS: I will use...

I tested LTC3454 at 1A output. LTC3454 has low efficiency at 1A and produces big amound of heat :( It works about 30 seconds until overheating and then switches off due to overheat protection. But at 0.7A (and less) it works fine.

It is already $172.99!!! Price is growing ($152.99 -> $172.99). Blue is very popular now :)
