If the sun was in the right place, anyway.It turns out that 4 ~300 watt photoflood bulbs in metal reflectors, a used box fan and some 2×4 stock makes a very effective portable death-ray, at least for small enough values of death.

Wood is great for many projects, but hand-cutting is difficult and time-consuming. He should have under-sized the hole a little and hammered it in there with the thermal glue.A smaller and more efficient power supply might be nice, too, but reuse what you’ve got I suppose!What about leaving the fan on the heatsink and wiring it to the PSU, then you’ll be able to use it forever, right? Don't go cheap on them. Make Your Own High Quality CO2 Lasercutter! Brilliant.As a kid, I found a big fresnel lens designed to turn a 19″ TV screen into something, uh, bigger, I guess.
The laser becomes very hot, and with electronics, heat is bad. That’s not a component you may find in an old pc.I think I will make this my first proper hackaday hack. heh heh…@xeracy – output power is somewhere between 100 and 200mW, probably. Reminds me of when I needed to put a few holes in the bottom of my trash cans for rain drainage and there was this very handy .22 lying about. It is not really a modification, but yes you can. Also, attempting to double the power to eight bulbs teaches you a lot about circuit breakers and introduces you to the physics of waste heat faster than you can say “Did you see that?
wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Nice design Drake!yes,this movie is ok, but how can we increase the watt for this laser source only using some DVD write laser diode and mirror, lens?? He fits the diode into the lens, then glues the assembly into a hole drilled through the processor heat sink. Could I modify these plans to use a green laser diode from a laser pointer with a wavelength of 532nm and a "maximum" output of 240mw (many people have gotten higher power output with this model)? If you had a 1m^2 magnifying glass, it would be delivering 1000 watts of power.Not that it matters, but I think he’s using the NorthBridge heatsink and not the GPU heatsinkAll of you people are seeming to forget is that he is just using available parts. Narrower linewidth = longer coherence length.Laser in dvd/blueray drives isn’t strong to do anything useful with it at all. The first thing you need to do is adjust the driver to your desired current. A driver is built using the LM317 variable regulator, resistor, power supply, and the GPU heat sink to keep things cool. Would be more interesting to see actual experiments that require powerful lasers…At least 16x DVD writer? or what its being over-driven to?That heatsink doesn’t look like it’s a very good fit. The laser dot is really bright.
Oh well.you are all stupid…a dead desktop most likely means that the psu is dead….how the f*ck are you going to power a laser diode with a dead power supply….“most likely”. there are 2 differnt sorts. Check out the video after the break to see the laser cutting tape, burning plastic, and lighting matches.wasnt burning hand, laser isnt that strong, it wont cut through metal@terc – saw that too.. lit the matches then stuck his hand in front of the beam to show em off.any one fancy a guess as to the laser’s wattage? After removing the cover, extract two of the main components, the PSU and the DVD burner. With too much heat, components wear out or fail completely. Learn how laser cutters can cut wood easily and quickly!

Water cooled, buy a bottle of CO2 (most gas supply places actually have the proper mix for lasers), a regulator, the transformer, and you’re in business. They’re not that expensive.

Burn Stuff! In this instructional guide, we will be learning how to build a high powered laser system out of simple household materials, which, in this case, are a broken down desktop with a DVD drive. Lasers can easily cause permanent damage to your eyes, even if you only look at the dot.All tip submissions are carefully reviewed before being publishedAlways wear eye protection while operating the laser.Wikihow and myself are not liable for any ham or damage done through anyone performing this experiment.This laser will burn through surfaces, so avoid contact with humans, animals, or flammable surfaces and materials.Make sure you perform the experiment in a controlled environment away from all flammable materials.Always make sure you have a fire extinguisher and first aid kit on hand.Do not perform this experiment unless and adult is present.Make sure all of your electrical connections are proper and insulated to avoid any electrical shock or fires.
