I can see where you're coming from now. My initial idea is incorrect since you can't exactly put an led and resistor in parallel with a switch since it in effect bypasses the switch completely. Like you said I'd need to put the led and resistor in parallel with the + and - output of the...

Thanks Pi R, Regarding the slight drain on the batteries that's kinda the point :beer: In effect it will remind the end user to remove the batteries once operation has finished. With these kind of obscenely powerful leadlights that can turn on extremely easily it is imperative that they do not...

I'm definitely down for one :D

Rather than creating a new thread I thought I'd ask a relevant question here :) I am looking to build a laser with essentially the same design elements as the one above and would like to have an led indicator which is always on when the batteries are in regardless of whether or not the laser is...

As long as the LED is on a DTP (direct-thermal-path) MCPCB then there shouldn't be any issues with it burning up, nor should there be any issues with using the stock aluminium heatsink. What host do you have this setup in? With my above post the 20A figure was a severe exaggeration... the...

There aren't many BLF members with xph70 builds let alone anyone here on LPF that I know of. All I would say is be careful with that kind of setup. Some members have recorded a current draw in excess of 20A from a pair of HE2's in series. You better have a good heatsink for it :p CORRECTION...

I wouldn't bother yourself with those LED's. That one in particular is way overpriced anyway. Here are a few examples that would require a fair bit of work but will invariably yield much better results. Mod: My latest super bright light 15000 LUMEN and 200+ kcd The Beast - Flood+Throw 960Kcd...

Totally awesome! Looks like you've got a very efficient diode :beer:

Re: Fs: CUSTOM LASER HOSTS FOR HIGHER POWERED BUILDS. NEW HOST 8/18/15 It's confirmed! Eghemus has long blonde hair! :crackup::crackup::crackup:

There is also RMM at Mountain Electronics. I'd consider him the DTR of the flashaholic community. He stocks almost every battery you would ever want and he is US based. He's my go to guy for batteries and chargers and everything in between :)

Re: Few things for sale Hmmmmmm, I'm quite sure that according to the replys to this thread that I expressed interest in the Ti-b before crazyspaz :) Perhaps Jeffrey can check his pms and see who PM'ed him first all those weeks ago :) I am still most definitely interested. Another PM sent ;)

I was 16 when I joined and was very arrogant and extremely ignorant (still am.. Haha :p) I'm still not sure what it is about lasers, but together with this community, my fascination has remained. Down here in NSW, winter is the best time of the year since all the fog rolls in and that's when...

Price please, and does it come with the arduino?

The route that you suggested appears to be the only sensible outcome considering geographical constraints. You've given me a lot to consider, it would seem to be the wisest choice to hook up an oscilloscope to check current ripple and start-up spikes, no matter what PS I end up purchasing...

Thank you for the advice Bionic, However, you are forgetting that unfortunately I live in Australia. That means two things. One, is that all the suggestions made by yourself and Cyparagon in previous threads from the likes of Agilent, Maxtech, Lambda, Leader, Xantrex, Sorenso, Kepco etc are...

I second that. All this secrecy which is withheld from all but the members who incessantly post ten times a day is quite unfair... :p

Yeah sure... Like what for example? As you can tell I am not well versed in this area at all. Perhaps some members here have a specific brand or model which has been proven reliable?

They should be fine considering that the SXD is a buck driver (I assume) Meaning that the input current draw will be lower than the output current to the diode. If you still want to use 18350's the Efest purple batteries are a 'slight' upgrade, they can handle a maximum 10A discharge :evil...

A Variable PS is something that I've always "needed" in my life... (merely to fuel my laser and flashlight 'addiction' :rolleyes:), so I've finally decided to get one. I'd like to keep costs below $100 if possible. my requirements are pretty basic, up to 10A would be nice but is not...
