Thats good then your all set to go, also my bad if i came off really stern in my post before, i just re-read it haha. :) i didnt mean to. Once you understand how lasers work its relativley easy to get nack for making them, i am no EE by any standards, and just picked this up about a month and...

On the topic of music i love the song palmdale by afroman :D, BTW welcom to the forum, i've learnt heaps here already, very good source for learning how electronics works, its like a double whammy, lasers and electronics.

First thing you should do is read alot, theres no point making a laser if you dont understand what it's all about, there are some really good beginer threads around (usualy stickied at the top of each different section), also when you say build your first laser do you want it to be fully DIY, or...

Well my brother and I (both computer lovers) were sitting in our tafe class thinking of things to do, when my bro came across Hak5 on revision3.com(which is a really cool internet TV hosting site) If your into computers you'll love this show. Its not specificaly about hacking (but they do have...

ahhhhh DUHH silly me.. i understand, just like how the ground wire from the driver is connected to the host which uses the host itself to reach the negative terminal on the bat. thanks for explaining.

Woahh before i came to this site, i was seriously intending to buy tonnes of stuff from awesome lasers, lucky i didnt then. Probably would have ruined the hobby for me, getting dodgey lasers and what not. p.s i love the tag at the bottom "T_j is watching you" :crackup:

One problem i see, there will still need to be wires running to the LD at the front. Excuse me for my ignorance if im wrong, or does the serial driver you mentioned cover this point (what do you mean serial device btw)

The idea is to leave enough room for the batteries and wires to fight snuggly , the rattle will be stoped by the wires, they will take up the free space the batteries dont fill. So your options are to use smaller batteries or larger host, but just because it is a bigger host doesnt always mean...

Im not sure if that would be reliable, but a much easier way (which i did) is to use the set of switches to switch on or of the power coming into the driver. If you wire it the way you are suggesting there would still be charge in the caps and when you switch it over POOF dead LD.... thats what...

Loving that light saber ad hahaha :D

OHH NOES!!, i must have been a bit rough with the diode and the +ve pin came unstuck :(, i hope it makes it to diode heaven :friend: On the other hand, the heatsink and double fan unit i salvaged from the xbox 360 did its job very well, i'll post pics of the finished laser when i receive the...

Also a little bit of advice for safety. If your using it to light ciggys you should add a beam stop/dump maybe 2 or so inches above the laser aperture, so the beam doesnt continue up and away, which could accidentaly hit yourself or someone standing around you in the eye while your focusing on...

WOAH!!... that would be so sweet to see, is that in germany?

:thanks: man, took a bit of work to get the driver all good, but im very pleased with it. :D Im using an aixis module for the 445 diode, and I just found the heatsink im going to use. Xbox lovers will probably hate me for it :p but the cpu heatsink in 'em is perfect, has a nice copper bottom...

haha no way thats gonna happen :p, ive already fiddled with it and taken it apart Ohhh bugger the FAC is broken so im sure this is a lost cause, i'll save this for later when im more confident and have reserched more about dpss laser systems and different types of optical methods. Thanks...

The first switch enables the power to be turned on without the laser coming on, making the box live I supose you'd call it. Also the fan when added will turn on at this stage. Then the next switch turns the laser on and off, if the unit gets hot the laser can be switched of without affecting...

Yeah, I havent decided yet how I should to cool it, I could probably shape down a square cpu heatsink..... major overkill, but what the heck (are they rated at 10W?) Missile switches FTW. With the cool fan grating aswell it looks kinda cold war era style or something, idk just my first...

Well after many trials and tribulations, I have almost completed my first laser, labby style build. Colour: blue 445 Power: somewhere in the region of 600mW - 1000mW. Only thing left to do is add a heatsink/fan and tidy up some wires. Couldn't wait to show you all on the forum, so here are...

i was thinking about this on the weekend when making my driver for my laser, i think everyone thinks about making a light saber at some point :D. Could you just modulate/pulse the laser at the fraction of the speed of light distance (i think i muddled something up there.) I found a calculator on...

ohhh silly noob mistake :P, it is a 9mm can :beer: for that. okay cool all that info was a big help, yeah this will take alot of fiddling and frustration, but im sure I can fix it :yh:, now to find a replacement. Thanks Had to google that one, ive been trying to find what that was for ages...
