Smart idea, about the mounting on the car :) Well i tried with 3x 18650 and then it Was only 3amp i tried using a psu to power it and at 14v it Was about 70w. ,Victor

Its all becouse i switched to a new lm317t and couldnt get the pins out :D

Hello, i just wanted to share this story :) The first lm317t driver i built was just for testing a lm317t so i built that one as fast as i could. It worked good with testload etc. then i built serveral more drivers, which i put some time into. Well i recived a 300mW ir laser today i took the...

Thats odd, i can send u the pictures in a pm if ur interested. Victor

Im able to see the pictures :0 -Victor

Should work by just getting new batteries, I dont know how the fuck i was thinking when i wrote this tread. 12v 5.5A is 66w to the flashlight driver which is good enough :) Max To the Led´s would be 90w which is a bit too much. thanks for the help guys

Dont u mean 110W?

Its 9x t6 led´s in a flashlight. It says that its "11k lumen" which it isnt. It worked fine with a 12v psu, since its running of 3x4V batteries normally. Dont really want to max out the Leds but i want about 1.5A to each one.

First thing, The batteries are to weak, Its running at 3.5 A with 3 newly charged (bad) 18650 Batteries. When hooked up to a psu its drawing 5.5A.

I said "11000 lumens" ;) Maneged to get 5,5 AMP by using 12v psu. I dont really care about battery life, 5 min battery time will be enough. If i could get it up to like 13,5A it would be awsome

The flashlight only draws 3Amp, can i build a new driver using the bigger model of the LM317 (is it LM358?) and get the Cree T6 Led to light at their full potential? It looks like the Cree T6 Can handle 3A each and now they are running @ about 0.33A each. -Victor

I have to upload it to the arduino, im going to use an old pc for the Next build. Right now i have to type in the steps into a .ini file for it to work, so its kind of difficult to make complex things atm. -Victor

Its ugly. My dad would sponsor me with NEMA 23 steppers + drivers to build a proper CNC if i got this one working. It was very cheap to build (exept for the laser) :) The build was improvised, didnt follow any blueprint. http://imgur.com/a/cHMVY 5x5cm Print area, not completly finished, the...

The circuit or the CNC ?

Dosent dark plastic react better to ir? -Victor

Im a noob within lasers but i would suggest that you build youtube own driver. I have a small CNC with a 1+ watt laser, i am using a 4x4x4(cm) aluminium cube for heatsink. -Victor

How high temperature Does the glass need to be? -Victor

Hello, How powerfull co2 laser do i need to engrave clear glass? Are the CO2 lasers from eBay any good? Already got the cooling system so if i got this right i only need a co2 laser tube and a psu to drive it? And glasses ofc :) -Victor

I switched to a new lm317t and it worked right away :) Now its running @ 1,22A. The burning capability stunned me :D Thanks for the help everyone and thanks for the fast shipping and the awsome m140 DTR -Victor
