I plan on picking up 2 M140 diodes, two 500mw mitsu's and 2 300mw mitsu's and seeing how well I can knife the two sets of reds into two seperate modules. These will be used (the 1 watter) in my projector, and the 600mw unit in a lab laser purely for burning. Correction optics are coming from...

lower the voltage and you lower the output power. Do not exceed 5V, you can kill the laser doing that. Find the threshold where the laser starts to lase with a variable power supply and this can be handy to line up experiments without a totally blinding spot to worry about (altho a 1 watter will...

Probably the same year I got mine - I remember I was 15 when it arrived - the NEC GLG 3030 - I built a home made power supply for it - using info from sams laser faq :) I remember it had a heap of big transistors and a big bank of caps that made one helluva bang when you shorted them prior to...

Get the smallest ups (even one with dead batteries and replace them) to make it bridge power outages. Even a little ups will run a wall wart to power this little red wonder for ages. Alternatively, hook up a battery in parallel with the wall wart (rechargeable of course). put some intelligent...

Seemed pretty on sync to me - watch the part where the horse neighs and you'll see a single abstract played in time to that sound. Yes I now have this darn tune stuck in my head too - remember it well :)

I agree with you there Antharak, I too can only see out of one eye. I have no workable lasers in my apartment as I sold my last set of laser glasses to a friend whom bought a 445nm laser from me. At the moment I cant justify putting money towards a set of glasses as I need a new laptop (to run...

My (4 month old) new toy. I bought this as a christmas present. It recieves from 0.6mhz to 999.999mhz with a few gaps here and there. Can listen in on two stations at once, and also transmits at 50 watts on both the vhf and uhf bands (ham frequencies). Its a remote head only unit, the main radio...

Yes they are stupidly addictive. Sadly I dont have any saftey glasses at the moment (I made a pointer for a good friend of mine whom I can trust to be safe and not silly with lasers) and gave him my glasses. I'll get some more soon tho, then I'll finish building my projector. I have a working...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Geez thats the last part I need for my tank - oh and some shells ;)

Actually it will - apply 5v to the modulation inputs of all 3 lasers at once, and short the ilda interlock pins on the 25pin ILDA dsub. BOOM white beam, full power. :) Just be careful where you point the projector when you do this. Its now become in effect a big laser pointer, doing circa...

I reckon you could (with some crafty machining - i.e. a small baseplate) bolt a set of scanners right up to the front of one of these, stick it in a box, add ilda ports or a show card, and you have a very cheap laser show scanner indeed. Be a great testing scanner - I might buy one of these and...

Way too much horsepower. Gotta back it off a bit ;) *pulls the throttles back to *WOAH big girl, WOAH!* (idle)

wow that 445 is stupid bright - 12 posts and your already further along with your laser than I am. Impressed is an understatement. Nice work :) I really need to pull my finger out and finish off my projector. Lasers can be had cheaply now, so I have no excuse; except the power bill which I must...

I am in the same boat as Silvershot - congrats Len! So pleased it worked for you. I am getting the cheaper projects done. $$$ will be more available in a few months once I stop squirreling money away for a new HF transciever. However spare cash has been spent on different things like a better...

I am also an amateur radio op as well - only got 2m online at the moment - saving for a FT-DX3000 :)

Major update for this folks - I've been sick and havent been able to work on lasers or electronics, but my doctor "found the trojan and fixed it good". I'm now well and playing with the power tools and stuff needed to make this bank. I have a few youtube videos to show! First of all, helping a...

Sounds like a long ranger LIDAR project - I could be wrong but! ;) Those powers are stupidly dangerous. Typically these wavelengths cant even be seen by a common video camera which can be used to see "normal (808nm and 1064)" IR ranges. Specialised NV or MIR vision gear is needed. Light of...

Nice projector! bet that Kvant cost you a pretty penny!

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please or get the guts out of a defibrillator. Heaps more current, insanely dangerous, and good for actually destroying stuff. Around 200J or so for a good one :)

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please First one: good for shocking the cat. The dumb cat will wonder what that was and come back for more :P If arced tip to tip, will produce a harmless ticking noise style arc. Second one: good for shocking the...
