content: Recently iv been keeping myself busy working on around 10 different projects, Mainly robots, but i decided on first making up some emp generators as they retail for the most amount of money, plus i had modified the design to allow for more functionality than others in the market, so it had something abit more going for it , I am hoping it will help fund the other stuff iv got going on, like my robotics, with basic models of cruder device's retailing for $200 £128.21The project was relatively cheap to produce, $38 ($35 + $3 for a white silkscreen) for 50 pieces from tinysine, they were nice enough to include 10 extra boards for free. the design is 5cm by 5cm, with a precut groove so that i could break the two parts of the board in half.Cost break down.PCB Design - £30 , I know a guy who is good with Altium and the newer stuff, as im only good with pcb wizard. But He's good to work with, lots of communication back and forth. i send a him drawing of the design and basic layout of the product, he tells me it will take a week or two, then he sends me the files to see if there needs to be any modifications.Tinysine PCB Printing (50pc + shipping) - £30 - took one 1 week.FRONTBACKComponents for 50+pc's - £30 - AliexpressSome of the components ( 100 555's £2.53)Wire for coils - £15Total cost £105Me messing about, waiting or the proper components to show up, got some nice rubber tops for the 6mm tactile switch and some 3mm flat led's.

content: Hm I'm puzzled, what would make this an "EMP generator"? If at all, this is some kind of cell phone (?) jammer or whatever or is that an infrared LED?Anyway, who would pay $200 for this? I'd also assume frequency jamming is not legal in most civilized countries...

content: Well thats just the board, different people use them for different things, destroying electronics, lighting bulbs, some people who want to test the security of there machines may use one, most on the market only affect the eeprom, mine is strong enough to effect the coin mech of most machines. i am aiming more towards a prepper market as they tend to spend abit of money...americans. there perfectly legal to sell. i was abit MEH on should i be selling them. especially improving on a design. thinking it could be seen as a "better way of robbing a bank" But im focusing it towards preppers, and if they pull it out because its ww3, the rapture or a slight delay in the Mayan doomsday prediction then good on them. GOD SAVE THE QUEEN!Heres afew examples,

content: The LED is just an indicator. This type of device also has two or more hand-wound coils that form a resonator circuit (not shown). The alleged purpose is to "hack" cash acceptors, although they might freeze any silicon electronics.And the buyers of these devices for hundreds of $ aren't hoping for free sodas, either. They are going after slot machines, which are capable of printing redeemable tickets.Of course they won't work on any modern machine, this is a very primitive bypass tool that might have worked 30 years ago. Today you would have to target the specific circuitry in the cash scanner. Still that doesn't stop con-artists selling them for big bucks to gullible consumers.

content: You'd be surprised, for effective cheating devices, the market will support very high prices.Several types are shown in this video:http://youtu.be/4K6FXe5XcHs?t=45m20s

content: So he's planning to sell a device that is designed to bypass societies mechanisms to people preparing for life after society has ended. I'm trying to work out who is more mad.The last thing you do before conning someone and acting or promoting others to act illegally is tell everyone........ I wish one young mind would grow up just a tad.

content: He stated the good purposes of it so think on positive side. Thinking negatively, kitchen knife should not be sold.

content: You could use this to test EMI susceptibility of devices in your neighborhood, like security cameras. I'm sure there are many possible uses.
