well nearly 2 years late but I'm going to say it anyway, awesome build Cyparagon. I actually agree with you with the red aura, makes the other colours stand out more I feel.

Mate, you are an absolute star. That is the exact one to which I was refering....Couldn't find it for love nor money :( Finally got fed of searching so just had to ask. I bow my head to your searching prowess and say "good job man, good job" Thanks, BIG TIME :D

Hello all, ages ago I found a video on here of laser show built into a PC case. It was a full on RGB scanner setup and was absolutely awesome. I have spent about 2 hours in total trawling through search results looking for it agai, but all to no avail. Anyone got any ideas of what I'm talking...

wow!! it's easier even than that....I totally forgot to meter the gnd side of the board. The 3V circuit is switched on the gnd side.....the 6V gnd is connected directly to the gnd where as the 3V goes through a controller IC on the board. So, I connect the gnd connection from the LD to the gnd...

just done a Wiki search on them, I think it might just work. Cheers Rog, I am learning little by little. I'll build some big beastie laser system one day :D Cheers, Fariniac .

ah yeah, thought about that. Not exactly sure how they work though tbh.

Hello all, I am trying to switch on 80mW red that I have in a display unit using the remote control (infra red). Here is what I am dealing with: Input that is controlled by the remote =3V Permant live to the LD = 6V. So, I am trying to find a relay type of situation, where the 3V causes the...

Nice one ReNNo, I'll set it up tomorrow and give it a bash :D Cheers for your help guys, it's been invaluable. Fariniac.

I know the LM can produce a lot of heat when lowering Volts or amps, but you can put a heatsink on a LM if you need to. This is the module I am using atm, the driver is crap it has to be said, but the diode has a lot of power in it...

It's actually pretty good with the smoke machine on, just enough haze to make the beams show up nice :D Now, I have a 30mW greenie on which the driver board heats up a lot after only about 10 seconds. The diode is very capable at that output and it has a tight beam. But this heating up has me...

Thanks Larry, I am building that circuit for my blu-ray right now. I have it set to 89ma on a RckStr driver and I am not too impressed with it's visibility (I have it in a nice heatsink so running for a longer time is not an issue) so bumping it up to 125ma should be much better for me :D Going...

Thanks for that guys :D I know enough about electronics to be dangerous, but not enough to be useful :D

ahh, wasn't sure the DDL driver was suitable, always thought that was only for Blu-Ray....D'OH!!...lol

Hello, stupid question time..again.... I have done a search, but cannot find an answer that fits. I need to build a driver for a LPC-815 Red long can diode, want to get it to abut 250-300mW. What's the best driver to build for it and supply voltage needed? Circuit diagram would also be...

ahh, now it makes sense. I have only ever used them to make a bridge rectifier, never for voltage drop. A lot of circuits suddenly make more sense..lol Cheers :D

Ok, silly electronics question here. Given that the 1n400x series diodes are basically used to prevent amperage flowing in the wrong direction by acting as a very low ohm resister in one direction and a high in the other, why would you need to put 6 of them in series? It's probably a daft...

Well as I posted somewhere else whilst asking a silly question, figured I'd better post in here as well. My name is Richard and I've been in love with laser light for a long long time. Many years ago a "fun pub" that I used to frequent had a 100mW Green laser in there which they only used to...

ah, cool. Thanks.  Is there a set voltage range for the 0's and 1's or does it vary from diode to diode? lol, you must have editted that as I was typing this q out...nvm,....cheers mate :D

Greets all, been reading these forums for ages, finally got off arse and joined :D And now the "idiot" question, I have earched and found all sorts of things to do with TTL but no info on what TTL actually is. So, what is TTL (including what TTL stands for) and how do I use it? I have just...
