What is Digg?52 Comments
- linker3000, on 10/12/2007, -2/+6That's ducking fangerous and technically very wrong:
1) you DO NOT short the final anode (the 'suction cup' directly to the chassis to discharge the CRT as this can damage stuff - the proper tool has a current limiting resistor.
2) Your average multimeter will die in a frazzle if you use it to test the final anode voltage and you do not have an EHT (Extra High Tension) adaptor IF you haven't successfully discharged the circuit.
3) Considering that the final anode voltage in a reasonable sized monitor can be in the order of 26KV ('a few KV' as it says in the article - my ass) you REALLY need to know what you are doing before you mess around with this kind of stuff.
No Digg as it's mind-blowingly, stupidly dangerous. - g-ram, on 10/12/2007, -0/+2Ariel loves you.

But dashingly funny!
+digg - ionix18, on 10/12/2007, -0/+1Wow, careful guys to not kill yourself. This is very dangerous as pointed by linker3000 and confirmed by me, an engineer :) I will add that your multimeter will die and your hand will be so close to the circuit and directly on the "insulated" conductive wire of the multimeter that an arc will probably occur and you will get shocked pretty hard. Ok, so I don't want to see this on CNN in 2 days: "Teen kills himself trying circuits posted on popular website digg.com" "Soccer moms creating petitions to bring down digg.com"

- Superfluous, on 10/12/2007, -0/+0the hot photoshopping on that image for the video link alone deserves a digg.

- inactive, on 10/12/2007, -0/+0The site was nice and fun to read! More people need to be like this guy.
- mikebeauchamp, on 10/12/2007, -0/+0Amusing story, but as stated above, this is terribly dangerous and done really stupidly.
- gamer31, on 10/12/2007, -0/+0"A flyback transformer in the monitor generates a few kV that is used to accelerate electrons in the CRT to hit the screen, and produce the pornographic images we all love to view because no girl will talk to us."
ROFL - MoreBeer, on 10/12/2007, -0/+0I collect/repair/restore old video games, and have to discharge CRTs every time I go to work on the monitor... The arcade folks schooled me to attach one end of the wire to a screwdriver, then cover all but the tip with electrical tape, attach the other end of the wire to the monitor's metal frame. Not sure if PCs have metal frames around them like the arcade monitors do, but any grounded metal should be fine.
I'm interested in linker3000's comment that damage can occur if shorting the anode directly to ground.. I've been doing it for years and not had a problem, but I'm too cheap to go out and buy the discharge tool. What can get hurt? the flyback?
thanks,
-mb - ViceVirtue, on 10/12/2007, -0/+0This is great - I'll have to give it a whirly burly some time! (being safe ofcourse...)

+digg just for that line. - camtech, on 10/12/2007, -0/+0haha, he uses 2 plug stirps instead of an extension cord.
- bonlebon, on 10/12/2007, -0/+0Thanks coredump0x01 for the tip.
- Sibertank, on 10/12/2007, -0/+0Yea, I love the picss and the name of the avi, some of this guys other mods are pretty funny..

There are several things that can become damaged, including the Hsync and Vsync transistors, various small IC's, basically any small circuit connected to the ground. It depends on the type of circuit, i've had a few monitors become damaged via direct short, and a few that haven't. As for the discharge tool, a 200k ohm resistor between the screwdriver lead and the ground will work just fine, you just have to hold the screwdriver on the anode for a little longer. The flyback transformer cannot become damaged via direct short, however, the power transistor that drives it can. - DeadlyCouncil, on 10/12/2007, -0/+0ZOMGSPLOSION!
I know a guy who's been an aries certified tech for 4 years, and he'd NEVER crack open a monitor. That ***** is DANGEROUS - teh_toaster, on 10/12/2007, -0/+0this aftrotech guy gives some fun reads for these cheapass dumpster-diving recycling projects
digg++ - RTAdams89, on 10/12/2007, -0/+0Funny thing. I foudnthis site and did this project just a few days ago. I got a 21 inch and therefore had a old 17 inch left over. I was able to get a great spark, but i could never get it to climb. I even tried using good rods and a a punch of other parts from homedepot, but it would still just spark, then charge for a second or two, spark again, and continue like that. I don't know if it was my monitor or the way I did it, but long story short I gave up after 3 days.
- TurdFergeson, on 10/12/2007, -0/+0hahaha, the whole site is hillarious.... i wish i could do mods like that
- cvncpu, on 10/12/2007, -0/+0this is one of the best modding sites out there, hands down!
- spectre_25gt, on 10/12/2007, -0/+0Any chance you could post a link to a place to purchase a discharge tool? I've been looking for one for quite some time. I even talked to a friend that does TV repairs and he doesn't know where to get one. It's like they stopped making the darned things...
Oh, the story... Umm, really freaking stupid, but entertaining. I'll digg it. - ,,|,_, on 10/12/2007, -0/+0e l e c t r o c u t i o n
- toaste, on 10/12/2007, -0/+0dupswapdrop has a point with the "it's kind of a simple IQ test, learn or die" thing -- poking around a disassembled monitor is just a great way to get yourself killed. I work summers at a computer and tv repair place, and if you don't know what you're doing you can either get badly electrocuted or implode the tube!
- panique, on 10/12/2007, -0/+0I forgot to add, the reason there's a current limiting resistor in the "pro" discharge tool is for the same reason - in case the tool is not properly grounded and the insulation of the tool fails, you only get a tingle instead of fibrillation.
- jakepaulus, on 10/12/2007, -0/+0the captions on the pictures alone...my gosh this is awesome.
- inactive, on 10/12/2007, -0/+0i herd that u connect a peice of wire to one end of a insulated screw driver and rapp ur screwdriver in electral tapel were rubber gloves and insluated shoes and connect the wire to like a mell wate rpipe and stick it under the suction cup and u shuld here a pop but like i dont no squat so dont try this or hold me liable i think the best way would be to simply chuck it in a swiming pool
- Spec8472, on 10/12/2007, -0/+0Seconded linker3000's comment.
Do this at your own peril.
You really have no idea how dangerous this ***** is. You may as well be playing soccer in an electrical substation.
To morebeer: You can (obviously) successfully discharge CRTs and other stuff using the highly insane wire-and-screwdriver trick. However: Don't do this with cheap tools, or tools that have been dropped/etc. Air gaps can form in the handle, and the metal portion of the tool which is embedded into the handle can probably give you a hefty zap.
BTW: Shorting a monitor to your PC case is probably a fast way to blow those sensitive (grounded) computer parts to hell.
Disclaimer: I am not an electrical engineer, but I have had informal training from one on what the heck to stay away from inside photocopiers, tvs and monitors. (Basically: Once you take the case off, any poking around near anything electrical will likely kill you if not extremely careful) - booc0mtaco, on 10/12/2007, -0/+0I cant believe how dangerous this is! OMG, i almost want to throw up.
Digg+ - bgladden, on 10/12/2007, -0/+0I have a science teacher who did this in class. Wasn't the safest thing in the world, but he was right out of college, so he's just a kid like us, and think its just as cool.
- ViceVirtue, on 10/12/2007, -0/+0That's a really awesome site! check out the vibrator :P hack and a half!

I like the comment by the company exec of audi-oh :P - dupswapdrop, on 10/12/2007, -0/+0Reminders me of when I was 14 and got blasted across the basement by the first flyback transformer I ever touched! You can have allot fun with high voltage, it's kind of a simple IQ test, learn or die.
And remember no matter how much black tape you put on it's only good for about 500 volts max.
Big time digg!!! - dcipjr, on 10/12/2007, -0/+0Digg because it's cool, but don't kill yourself doing this.
- Afrochu, on 10/12/2007, -0/+0OMG DONT DISCHARGE IT THAT WAY YOU MIGHT DESTROY A TRANSISTOR OMGZ
Jesus christ people wtf. The monitor was dead to start with. It wouldn't even display a picture. Do you think anyone who plans to try this gives a flying crap about damaging the Vsync transistor on a 13" monitor made in 1987 that is worth less than the electricity being used to power it? - bonlebon, on 10/12/2007, -0/+0Also rubber gloves and isolated shoes/boots should keep you safe, I've seen overconfident technicians that don't care about these measures.
- linker3000, on 10/12/2007, -0/+0..oh yeah, I am a qualified electronics engineer by the way (for what it's worth)
- bonlebon, on 10/12/2007, -0/+0Actually many monitors and tv sets got very clear stickers warning about hazards, one is being careful and other spreading terror, use the common sense, if you are one of those that need a reminder over hot coffee (not the GTA hack) at your local starbuck stay away of this kind of hacks.
- glitchbit, on 10/12/2007, -0/+0sir your article just KILLED two Kittens!
- panique, on 10/12/2007, -0/+0morebeer: Electricity always follows the path of least resistance, just like a good programmer. The problem with using an ad hoc screwdriver with an alligator lead is the screwdriver handle doesn't provide adequate enough insulation to protect you in case your ground isn't really grounded. You become the ground in such a case, and in the process defeat the entire purpose of discharging the tube in the first place.
- inactive, on 10/12/2007, -0/+0by the way if u touch the underside of teh suction cup u will die
- Afrochu, on 10/12/2007, -0/+0Everyone loves Ariel.

- Shroomie, on 10/12/2007, -1/+0That's prety old. There's a bunh of other cazy ***** on that site too.
I used a Neon Sign Transformer sign to make my Jacob's Ladder awhile back. - antisthenex, on 10/12/2007, -2/+0This isn't new. I've heard of it many times before this.
