Well, I had an old LCD lying around from an old Pentium 1. Sure, it was a decent LCD, but without a controller board, it was pretty much useless to me and collecting dust. So I took out the LCD (cracking it in the process, so there was no going back now), and hooked up the inverter wires to a 9V 350 mA wall adapter. It is labeled at 21V, but 9V is plenty bright for its purpose. (you can see the brightness in the comparison picture my 200 nit T61 LCD next to the finished light.)

Once I build a desk for my room, this thing will be mounted on the top of something, about 1-1.5 feet above my workstation.

Anyways, it's kind of neat in the meantime. Here's some pictures:

If you have a broken LCD lying around, it's a fun and simple little project. Just don't touch the inverter while it's plugged in, it's a rather heavy shock. Guess what I did. I smelled burning skin. Didn't see any, but I guess there was enough singed to make a smell.

doesn't take much. I once crossed the wires on two D batters without noticing until I smelled my skin burning. the wires were really thin, too.

I've never shocked or electrical-burned myself, but I've shorted a few batteries and fried several electronic components. One of the most memorable ones involved a transistor. I didn't know how much resistance I needed, so I used a potentiometer. The transistor controlled a LED, so when I turned the pot all the way to the right it was really bright! Of course this put about 6 volts into the base of my cheap radioshack (it was still radioshack back then) transistor. I guess it fused the silicon or something, because after that it was pretty much a decorative wire (stayed on). Did I mention it got really hot and smelled like burning electronics?

I had a similar experience with a transistor before. I accidentally had hooked up 12v through the base and emitter. So i turn around and flip on the power supply. I hear a little pop and turn around to find my transistor had split in two! One half had one leg and the other had two.

I caught my pants on fire once. ONCE. I will never use a stock psone screen aagain. Must be led modded, or I will not turn it on.

I can't tell if I'm scared to portablize or just still laughing at the picture you placed in my mind. No offense ShockSlayer

Time for a new entry to the MSpaint abomination thread.

you're too slow

Worst thing I did was a few years ago. Decided to take apart an old camera; opened it up, and got a shock from the circuit responsible for powering the flash. Wasn't fun...

If you buy some cheap disposable cameras, you can make an AA battery powered stun circuit easily, Bacteria; Imagine being able to inflict that pain upoun those you hate whenever you want!

(I always thought a portable that shocked people would be funny. Then I remembered they would drop/throw it, so an original gameboy would be the only suitable console. )

I had some friends that took apart a disposable camera and ****ed around with it. They figured out the contacts used for the flash and would touch a pencil or something to it causing a loud crack. Of course they would do it during class

I knew someone who built an electronic shock-circuit into his shoe. he could shock people by touching them.

Out of interest, how many volts do these flash camera circuits generate to give such a shock? (and what is an unsafe level for a person to take)? I recall it made my hand clasp and tried stopping me dropping the camera and I felt a mild pain in my brain, fortunately the camera was held badly initially so it fell quickly. Quite a shock!

The standard is 330v from the capacitor, about 400v from the charger in the low milliamp range. That kind of shock is nowhere near fatal unless you stuck probes into your heart or something.

The really bad shock is what you get from a fully charged capacitor, the charger output is not so bad. (Still no fun, though)

I should post some pictures of one of my first electronics projects, years ago... "Stun Knuckles". Basically, some gloves rigged up with a few caps, chargers, and some springs on the knuckles to discharge a NASTY shock! I put them into retirement after I realized that putting 6 of these caps in parallel actually put the power in the somewhat dangerous range.... Remember, voltage is not harmful, it is the amperage! All the volts do is allow it to travel farther faster, so it wil hurt more, but not kill you. Heck, most police Tasers are in the 90,000v range.

Yes, post details - interesting!

I had stupidly removed the cells first; and not flashed the flash first to discharge them before opening up the camera - so in effect the system was fully charged and ready for someone stupid to open the system up and touch the circuit...
