I think that you should get one from a paint brush it has one
Hey there little friend , i should have directly commented on your post but am replying for a reason , the circuit you gave is very correct up to your level (the circuit given by the burgersbite is just an cleaner representation of yours) and i gotta say you explained that stuff pretty well , in a bit more technical terms , the oscillator you've made acts like a feedback oscillator and when you put the receiver coil above it , what actually happens is mutual induction , or the rate of change of flux in the first coil results in the induced E.M.F in the other other coil.The higher the frequency of the oscillator the higher voltage you get , singe e=-d(flux) / dt , the smaller time it takes for one oscillation the higher emf you induce but sadly there is a factor which limits you to get 1000000 volts out of that battery , it is the more voltage to gain up , the more current you'll loose and at some point there will be negligible current through the second coil though the voltage is pretty high. So you cant put up good voltage with that battery. So my point was you're explanation of this circuit was mind blowing and super easy to understand. Keep up the good work kid.Regards,Samad Haque

can i obtain a microphone from a a earphone set
Hello can i use my phone charger which can give output upto 1A and 5V
wonderful i tried
man i love i saved cash for buying a soldering machine then i saw your project ,, i ws so happy to it cause i had items to make it in my garage thank you bro
Hey thanks for the post!I'm sure it's helped a lot of people.I found this while looking for a way to do something slightly different.I have a few bluetooth headsets, but they trap me a few feet near the computer.Is there a way to set your computer input/output to a device in my network instead?That would allow people to walk their whole house.If that is even remotely doable, I'm pretty sure it a well scripted video would have a huge number of backers at kickstarter...
