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!

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.

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 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. Everybody has a list of places to visit, or things to do, but what is your making bucket list?What should everybody make before they die?Daily Mail articleBuy the book onlineOne Hundred Scientific Things To Do Before You Die.

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.

Will someone write up the plans for a HEAVY-DUTY ankle and wrist weight. I have been searching online for a company that will make custom weighted wrist and ankle weights but there aren't any. I'm wanting to make a 50 lb for the arms and 100 lb for the legs. I'm thinking along the lines of several iron or lead bars strapped together with a nylon fiber or other strong material. I've only ever done projects in high-school, where materials were provided, so I don't really know where to get the materials needed. Please help.

Once you get going with your new SDR dongle you soon realise that it is little fun with the supplied antenna - if it came with one...Local stations, police (unencrypted) and so on is all fine with the short antennas.But if you want to get weaker stations or even track some satellites you are as lost as trying to get anything in the 160m band on your screen.Obvious way out is to get an external antenna.Depending on your needs and layout at home you might be lucky to find a ready to go option at some cost.In most cases though you will need more than the 3-5m that come with the usual antennas for car use.And not all base station antennas come with enough cable - keep in mind that hieght above ground and no obstructions close by count...With RG58 cable already being quite expensive a lot people consider the cheap 75Ohm TV cable as an alternative...Can we use 75Ohm antenna cable for our SDR needs?Of course we can!We only need to make sure that at the antenna end AND the receiver end the cable acts and appears like a 50Ohm cable.Especially if you need a really long cable in range of over 20m the TV cable shines with less loss that can't be ignored.Let me try to explain it the simple way first:You TV needs 75Ohm but the good old dipole antenna provides 300Ohm.The so called BALUN that connects the actual antenna with cable matches the antenna to the required 75Ohm impedance for the cable and TV.Like the TV, we don't transmit anything, so we don't have to care about what happens if power would go to the antenna - it is not a radio in the common sense, we just listen ;)There are many options available to match any impedance to any other but in our case a lenght of coax pairs is all that is needed.1/12 of the wavelength for the 75 and 50Ohm cable and we have a match.But.....You are right this simple option does not really work if you want to listen to a lot of different frequencies.What works fine for the TV also works fine on both ends!I assume you use an antenna for the common 50Ohm system and a standard 50Ohm SDR module or receiver.Two simple transformers will do the trick just fine and allow us to use cheap 75Ohm TV cable.The one on the antenna end provides 50Ohm for the antenna and 75Ohm for the cable.For the receiver the transformer is the same type but connected in reverse.You can look up how to make one with a simple ferrite torioid core and wire or coax but also order them from your favourite Chinese seller in the usual online markets.Add an antenna switch and you can use multiple antennas optimised for the frequency in question with dirt cheap TV cable.Just make sure to put the balun in a metal enclosure that is connected to the braid of the coax on both ends.

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.

And I would like to recycle it in a new project in my Arduino.The problem I am faced with is that I don't know very well how to connect it to my breadboard/Arduino.I have found a couple of relatively cheap options but I thought best to double check before spending money on something I might not need."Socket" https://www.adafruit.com/product/1773PCB: https://www.adafruit.com/product/1492attached are pictures of the display in question.This would require a bit fancy soldering which I think I should manage to do without melting the pcb.however If anyone can suggest a simpler way, (or if thi is completely wrong).thanks everyone.c

From what I understand each series would need a resistor but I am not sure if the motorcycle battery puts out enough mA to support the total number of LED's. I am a beginner so I may have this all totally wrong, hopefully someone can point me in the right direction. Thanks for the help!
