This is the very first fully electronically operated laser. I used to have an old upload using two cold lasers and one hot one, but that was a fail. So I changed it a LOT, added different lasers, and added a fully electronic control system. One click cutting, and it automatically turns itself off.



After much testing, I decided on using a preheating system to preheat the material to be cut before active cutting to cut through it. I tested this system, and the preheating to 300 C prior to cutting still yields a bottom chunk of material.

EDIT: HUGE update!!! Added the blast cycle, so excess lava is blown away. This, combined with a new electronics system, makes for a much cleaner cut most of the time.

Feedback? Questions? Comments? Ideas? Tell me in the comments, NOT in the tags.

All right, then, show me a laser with 3 "gamma ray" beams that has a preheat stage, displays the different stages, with one-spark action and an automatic shutdown that uses a sensor rather than a timer. And the whole thing has to be built before the date this one was made, 3/17/11, which was the initial release.

THAT is why I call this the first one of it's kind.

thanks! I am STILL testing this. It took me about 2 hours to complete it, so about an hour to build the laser and get the photons reflecting right, and another hour to do the circuitry and Wi-Fi and work out the bugs.

BTW, anyone have another way of heating the preheat lasers? Currently they only put out about 200 C at contact, I am looking for a small, consistent laser that puts out 1000, which by my calculations will result in a 500 C preheat.

yeah, it can cut through battery, just slowly. if you want to see a laser that is manually operated, but can cut through battery quicker, check out my "Gamma Beam" laser.

2) If you read it (no edits), it says, "this is the first fully electronically operated laser." Fully electronically operated, not just electronically operated. The difference between automatic and semi-automatic. It's the first of it's kind because it runs itself, only requiring to user to press fire, rather than an on-off switch. Get it now?

Where is YOUR laser now?

assuming you mean for the preheat lasers, I found a solution. 2 heating life and 1 still/cooling life in one mirror, and 3 still/cooling life in the final mirror for both preheat lasers brings METL just below melting point, which was precisely what I had wanted.
