I just got a 50,000 volt Tesla coil (Oudin coil) for Christmas. I dont have a clue what i could use it for, i need inspiration. My uncle likes to surprise me with semi random things so other than shocking metal tables i just dont know what to do with it. ---from teachersource.com (where he ordered it)While more accurately called an Oudin Coil, these are commonly referred to as a hand-held "Tesla Coil." This coil is self-contained in a heavy duty Bakelite case which forms a convenient handle. The spark is adjustable from 10,000 to 50,000 volts at frequencies of approximately 1/2 megahertz. The high frequency spark produced is about 1" long and can be used for a wide array of applications. An instrument like this is intended for intermittent use only and must be turned off after 10 minutes of use. The electrode furnished is approximately 2" long and the instrument is furnished with an intensity adjusting knob. For 115v, 50/60 Hz. An improved SAFETY FEATURE is the ON/OFF momentary switch which is in the handle. This makes our Oudin Coil extra safe for classroom use. (Runs on standard North American line current, 110 volts 60 Hz)

Spotted on the streets of NYC is this gumball machine that's been converted into an idea dispenser. For just fifty cents you get an idea in a plastic container. No word on how good the ideas are or if anyone's found them valuable. The photographer sadly did not buy any of the ideas for sale.Are ideas hard to come by? How much would you pay for a good idea?

Yesterday we looked at the Top 50 commenters for 2008 and today we'll be looking at the numbers for the top 50 Instructables of 2008. Since there's no one way of declaring a list of Instructables, we created three top 50 lists. These cover Instructables in order of rating, pageviews, and comments.

I'm looking a decent Airsoft AEG Rifle for no more than $50. I know that $50 is a very low budget, but I only want this for small games with a couple friends in backyards/woods. Low FPS is fine. Only real requirement (besides it being an AEG rifle) is that it doesn't fall apart right as I get it. The only thing I've been able to find is a Crosman Pulse R71/R73, and both seem to have poor build quality, therefore a little over priced. Thanks a bunch!

Im trying to wire a string of 50 LED's that are 200mA each. They are all connected in one long string, end to end (in series, I think). I'm having trouble trying to figure out what kind of power source and resistors to use and how to wire the resistors in. In the past I've wired 1 or 2 LED's to a 12 volt power source using a couple of resistors in parallel, but this project is much bigger and I'm worried about current loss and the very high voltage needed to power a string of 50 2 or 4 volt LED's in series... is that like, 100000 volts, or what?? Any guidance would be appreciated.

I'm not a huge fan of steampunk, with the exception of Lady Clankington ;-), simply because much, nay most of it, exists just as a prop, not a a functional object. So when I ran across this beautiful rifle, I just had to share. The most amazing thing, is that someone handcrafted this in their home machine shop. Truly a master craftsman.

I'm looking for a decent Airsoft AEG pistol for under $50. I realize that for the same price I could get a much nicer spring one. but right now I'm looking for an electrical one. FPS can be low, I don't need things like blowback. It just can't absolutely suck and fall apart in a week. Thanks!

The man who co-wrote the best-selling adventure travel guide 100 Things To Do Before You Die has died at the age of 47.Unfortunately, Dave Freeman had only visited half the places mentioned in his book whose recommendations included a voodoo pilgrimage to Haiti and running with bulls in Pamplona, Spain.Ironically, he died in a simple domestic accident, falling over at his home in Venice, California, and hitting his head. According to co-author Neil Teplica, his friend's mantra was: 'You should live every day like it would be your last. There's not many people who do.'Mr Teplica said: 'He didn't have enough days but he lived the life he wrote about.'The guide, which was subtitled Travel Events You Just Can't Miss, started life as a regular website feature called The Coolest Place on Earth. As readers started sending in reports of wild and wonderful festivals around the globe, the two men vowed to try them all out.

OK,so we've got this new LED flatscreen.There are frequent power disruptions,power failures,load shedding etc where I stay and most people have an inverter installed in their homes to run their devices during power cuts.We have an inverter in our home too but here's the problem-When the power from the mains is cut and the inverter starts to do its role,there's a small delay between this process which is hardly noticable but long enough to shut my TV off.Say if we are watching a program and suddenly there is a power failure,all the devices continue to work normally on the inverter except the T.v which has to be turned 'ON' again by using the power key in the tv remoye or on its panel.I guess it isn't good for a Tv to just shut off like that without first turning it 'OFF' with its remote.I thought if I could build an inverter that can run on a rechargeable 12 volts battery and power the T.V for a few seconds,filling in that delay I mentioned above.This way I could prevent my T.V from turning 'OFF' like that and could ensure it a greater life.I intent to add this new inverter as a backup power source until power from the main inverter begins to get utilised.I've included a schematic to give you a better understanding of what I intent to make.Thanks in advance for the time you spent on helping me out.

Good day to all, i'm new to this site hope i can gain more knowledge in electronics here, since i have been doing alot of programming lately.. i am planning to build my first higher wattage amplifier for both guitar and bass, i already have built smokey amp and its other cousins like the ruby amp and some guitar effects. i will build the two amps simultaneously and put it in one housing.. the speakers will be separated and also the circuits and all.. does any one have schematics for this kind of amplifiers?? it should bea solid state amplifier, because its hard to find tubes here and also it is expensive.. correct me if i'm wrong 1. "instrument >>>preamp>>>poweramp>>>>speaker" ? 2. is it possible for example to use a smokey amp as the preamp section and connect it to a 50 watt power amp? 3. what type of speaker should i use for the guitar and for the bass? should it be a woofer or sub-woofer? coz i dont have a clue on speakers.. tanx in advance..

Hey. So i have this led light panel which was damaged by some water that leaked through my ceiling from heavy rain.My dad wanted me to try repair it(he didn't want to spend another 100$ to buy a new one) so i did and i found in that the led panel has 4 strips of ca 70 leds each 1 m length each, powerd by this guy http://imgur.com/a/dhNUb 2 of those led strips wouldn't work anymore so i had one led strip of 2 m which i bought for some project , and i wanted to replace the ones that aren't working anymore but they are working pretty well on 12V 1000ma Dc(they are heating pretty fast but for that i think i will need some resistors for that or i don't know). So i'm asking how can i convert 50-45V 1200mA Ac to 12V 1000mA Ac so that i won't burn that led strip that works on lower current. A schematic will be all i need and the components that requires. P.S : I'm a begginer in electronics and i don't know that much about them and i'm looking forward in learning more sorry for the long story.
