Just so your 100% sure, if you are putting together the adjustable voltage circuit, you need to take the +12v (positive yellow I believe) wire and the black (ground) wire. Not the +12v and -12v, otherwise you'll end up with 0-24v but you'll only be able to draw the maximum current the -12V line...

The greens down to 109$ + shipping now! I can't go any lower than that people. The modules alone were 105$ when they were for sale on O-like, you're essentially getting a free Ehgemus host!

sometimes the best host is no host :shhh: technically it's not a host, but I like the way it's laid out all the same, kind of has a geeky feel to it with the wires showing. I found the same battery in a crappy little remote control helicopter I have here after I ripped it to bits so I plan...

I love you! /no homo (+rep to you both for finding it for me) Such a sweet host, my favourite :)

Could well be? I did think it was wannaburns I did a search through his threads but couldn't come across it, do you have a link? cheers /sorry the semi-threadjack

Cool concepts :D but the host I was thinking of was actually made into a laser, it was fairly simple if I remember correctly, straight no RPL head style to it, it was fairly short as well.

I remember seeing a great custom brass/aluminium or brass/copper or copper and aluminium I can't remember which host posted a few months ago and I remember it looking and being designed really well. If anyone could find a link to it, I'd be very grateful, I've tried searching but couldn't...

I was half expecting to see mohrenberg on topgear going round the track :p Good work on the order moh :)

I did a quick online search for an Aus electronics site, came across this one: LM350K +1.2-32V 3A Voltage Regulator - Jaycar Electronics Whether or not it's any good I'm not sure, might be worth checking out some others though for postage quotes etc.

Bump!

If he follows the wikihow link I posted he should be ok, they use a 10W 10ohm load resistor connected across the red and black wires.

They are generally a better alternative to LM317's, an upgraded version if you like. I'm not too sure about what the price should be though, I was very kindly donated one by a member. It might be worth checking on digikey or sparkfun or something too see what they're prices are as a comparison

Dam they look awesome

Also, the divergance on the laserglow lasers is second to none, especially on the greenies. The range on it will be far superior than your 445nm, simply because the beam will stay thinner and look more intense for a great distance.

Might be worth looking into a kinect hack for this kind of thing, might be able to get the IR dots to register the movement of the copter.

If it's a 100mW before you use the driver, and then it's 5mW after the driver then yes I would say it's a problem with the driver. Don't really know what else you want anyone to say as you've given no information as to what your laser is, what driver your using to get TTL modulation or what...

Very nice build, Will it light a match?

I don't agree with drink driving regardless of your BAC. I don't think anyone has the right to put other peoples lives at risk just because you feel you can handle more drink than other people. If you drink, don't drive a car, it's not difficult.

photonic goodness :)
