    arggh! help driver keeps shorting out in heatsink?

    tried that didn't work, it seems its not getting ground through heatsink to driver. it works if i touch the ring on the underside with ground but if i try and put ground on the heatsink as it would be in the ultrafirewf501b . My battery starts smoking. It seems the driver isn't actually...

    arggh! help driver keeps shorting out in heatsink?

    I have a amc7135 driver which works fine as long as its not in the heatsink, but as soon as i put it in, the terminal points on the driver to the diode are to close to the rim and are touching the heatsink and it shorts out and battery gets very hot. Any ideas how i can insulate them from the...

    Need host to fit amc7135 driver and 9mm to-5 infrared laser diode, any ideas?

    Just cuz it was cheaper at the time when I bought it otherwise would have gone for blue one. I would like to get some glasses but they are so expensive can you point me in right direction for cheap infrared glasses as well?

    Need host to fit amc7135 driver and 9mm to-5 infrared laser diode, any ideas?

    Ok got 501b delivered and have my diode currently in a 9mm axis module. But I'm gonna need a heatsink to fit the module and the 501b. Can anyone recommend a cheap one?

    Need host to fit amc7135 driver and 9mm to-5 infrared laser diode, any ideas?

    thanks gone for Ultrafire 501b, what about distance and lens?

    Need host to fit amc7135 driver and 9mm to-5 infrared laser diode, any ideas?

    Need host to fit amc7135 driver and 9mm to-5 infrared laser diode, any ideas? Preferably to fit ultra fire 18650 battery as well Also how can I get a further distance, only seems to burn at about 9 inches, do I need a different lens or something?

    DIY Homemade laser diode driver

    Can you recommend a host kit to fit this circular driver and to-5 9mm infra red laser. Driver works great By the way. Just trying to figure out how to get more distance out of it. At the moment it only burns at a maximum distance of 9" do I need a special sort of lens to get further distance?

    DIY Homemade laser diode driver

    It's bugging me how an earth it is even possible to get 1.5 amps at 2v as tried calculations with ohms law and they don't seem to work

    DIY Homemade laser diode driver

    Thanks, but what I'm confused about with laser diodes is the relationship between forward voltage and amps needed as you can get different drivers that output different voltages but all put out the same constant current. I.e if forward voltage is 2.2 - -2.6 and amps are 1.2-1.6. What will happen...

    DIY Homemade laser diode driver

    What led driver will that work? Which version for max burning and what lens would you recommend? I noticed on this listing PWM 5Mode AMC 7135 2800mA driver for SSC P7, CREE MC-E CREE XML 3-4.5V input | eBay it doesn't say what the output voltage is? Or is there just a pot that you turn to tune...

    DIY Homemade laser diode driver

    I'm trying to make a driver for a 1000-1500 mw infrared diode with the lm317lz regulator. The diode needs 2.0 -2.2v and 1.2-1.6 amps. However I'm struggling to figure out how to regulate the voltage and current as I'm not sure what resistor and pot I need for correct current and how to get 2.2v...
