Got a hold of a 1W> 532nm laser system (judjing by the model/make, should be outing anywhere from 1.3W-1.8W).
Need to get some optical power readings later.

That, minus the red. (B/G projector)
I have some 35K scanners on hand, and am working on a large knife-edged 445nm array to ballance out the green. might throw in a 200mw-300mw 650nm/660nm for shits and giggles. |

Interesting stuff:-
1) Homemade EL using old DVDR disk split down and treated with boric acid electrolysis then coated with phosphor.
2) Hacked EL T-shirt so all pixels independently controllable by careful use of HV to "split" the ITO inside the panel.
3) Really ancient analogue meter
4) Macro shot of the CCD linear sensor from an old HP AIO scan head.
5) No comment!

Some photos from a CNC machine I am currently working on in a lab. The machine was built by a mechanical engineering student here a few years ago, then he dropped engineering all together. I was given the task of restoring this machine, and so far I have seen: some of the worst wiring in my life (but hey, he was an ME student, not an EE); motor shafts bent (that's right, not out of alignment, BENT); encoders without wheels on the inside; an arcade style E-Stop button that didn't do its job; parts harvesting with no apparent regards for safety (someone removed something that used 120V. They left the 120V lines free hanging inside the all metal control box and also didn't bother to label it or tell anyone they did anything with it); and the X axis in motion scrapes against the steel support frame, which has standing legs that are not of all equal lengths.. Needless to say I've had my work cut out for me.
But it will be worth it. I may not own the machine, but I have 24 hour access to the lab with it and freedom of use and modification as long as I don't break the expensive motors.
It has an Optical Grade XY table, I just installed 900W AC Servo Motors for the XY, and am planning on an at least 400W AC servo for the Z-axis; we have a copy of Mach, and every CAD software imaginable on the school machines and I have the entire Autodesk suite on all of my personal computers to design things at home; the homemade varieties of CNC machines with these motors have achieved unbelievable results of milling 1/2" Aluminum with a 0.001" tolerances (with pics and vids to prove it BTW). And that's just what they've documented in their logs, I could maybe even push it more!
Anyways, the photos.
The X axis drive screw and the magnetic limit and home switches.
The shiny new motor control board to replace the Frankenstein'd rats nest of wires (of which I have no pics, but I wish I did now). The board supports four axis, and an X' axis; limit switches for each axis, e-stop; power conditioning; etc. Then each of the motor drivers are also mounted. You can also see the new E-Stop switches, which are a huge step up from a big read Arcade game button that didn't work.
One of the 900W AC servo motors mounted to the table. I may have to remake the aluminum mounts as I changed the gear sizes and may not be able to get the right size belt.
A photo of the Z-axis sled, with the Stepper motor that was already installed, but will be replaced by a smaller version of the XY motors once the rest of the table is ready (we didn't want to blow all of the $1k budget at once, and we hadn't picked a milling tool yet which could make a difference).

An update from Page 67... It's come a long way -
And what happens when you shove over 350 horses through a Suzuki clutch!
Not such a cool picture...

A recent photo from my current endeavour to get the largest, most destructive arcs out of a single MOT :D
The setup has a MOT with a tiny little toroidal choke on the input and 5uF of capacitors on the hot side. The transformer boils after about a minute :)

GBD: Quite a collection you have there ;) what voltage are they? you could make a very primitive vehicle, or a spot welder?
XravenorX: Very nice, looks like an explosion! just cut up my MOT, decided its far too dangerous for me. Bet the primary is enjoying its little 'heat treatment' ;) |

They are 385v/4700uF... not much use other then to make things go bang and to act as a filtration device. (not enough capacitance for vehicular use, and for spot welder, well, it mostly vaporizes then welds) |

That makes for 55,732.6 Joules if I'm not mistaken... Particular project in the works?

That is correct, or 289.6 Coulombs for a 160 bank.
Im only making a bank of 16 for now for some ETG experimenting.... should I ever feel like turning gun into cannon.. I guess thats a project on its own.

Haha, yeah the arcs grow to about 40cm and are too bright to look at directly. I can hear the windings creak as it cools down, so I doubt it'll last much longer, but I have 2 more to replace it, and a big 3 ohm resistive grid to use as ballast. I wonder if 2 MOTs can handle 19.2kVA >:D |

what happened to this thread? Just no more cool pics O_o
Here's my shotgun i got recently and my shooting case.
Got 7 1/2 shot for skeet and clay sports, rubber buck for the home (had my bike stolen and car broken into this month alone, and my house has been burglarized in the past with us in it)

Nice gun!
Ahhhhh sounds like its time to move….uggggggggggggg Do you have an alarm system in your house?
OK you got me excited. Here a cool pic for you…just in case you are wondering if the new Archangel M1A Precision Stock @  fits a Springfield M1A. After three hours of very careful filing, this new stock just fits snug and tight. Cannot wait till this weekend to try it out indeed! Here turkey, hee hee!

Very Nice! I actually have to modify my stock a little, this gun is so lightweight that the 12ga shells have a phenomenal amount of kick (bruised a friend's shoulder even). I'm debating on whether to adjust the gun's weight or just try to custom fit on a spring pad (may just make one from the ground up).
The condo has an alarm but it is not currently active (company is different from other family properties, needs to be rewired, etc). We are going to reactivate it soon but are going to look into the company that has the unit currently installed first.
I also recently replaced the deadbolt myself, the previous one allowed for an inch of door movement while locked, and was able to be Raked open. With all of my gear I am taking it seriously. And if I catch someone breaking into my car again, they're getting a rubber slug to the back. If they enter my home, in lieu of rubber they shall taste lead.
I would electrify the car and do some other things, but unfortunately that is a felony here...

Best thing would be to add a butt pad to stock and have the barrel ported. That will calm that puppy down and heck maybe fire 3 inch shells! |

awesome, it just needs a rotor now 
Did you make a loop in the built in LUA scripting to do that? I've done a couple of animations on FEMM like that with motors, but never actually got around to assembling them into an animation |
