So I've been having the idea of making a small EMP capable of making cheap electronics behave in a silly manner, but being the igni't fool I am, I have no idea about electronics or how to plan construction of such a device.
I was thinking of a case, some capacitors, a switch or 2 (One for charging and one for discharging the caps in one hit) an inductor coil with a ferrite core and of course a power supply.
How would I go about planning a proper going-about this? Any books I could use for this particular plan?
I'd like to do this properly and neatly, just so I can make sure I don't make things go pop that aren't supposed to go pop.
Also; how would I go about making sure the magnetic field points outwards instead of back into my own device?
Why am I getting funnies? Did I say something stupid? :(

This is a project that requires alot of thought to be put in, check the Chryseus's OP, its got alot of good links to books for umbrella EE. I say this, as this device isn't something to be trifled with both legally and physically (The power for a significant EMP device is rather dangerous).
Catch up on basic circuit theory and EM theory (Maxwell, Gauss, etc), to know what your end goal *specifically* is.

Alright, sweet. Thanks.
Though it feels like you fear I'm trying to make some 100m+ range EMP, I'm only intending a 5cm max range just to make calculators and other little things act funny.

You can nab a discarded microwave and achieve the effect you so desire.
Just throw a 2$ calculator in there and see the magic happen.
Where can I order parts [u]that accepts paypal[/u] other than ebay?
I need a pile of 4-6mm radial capacitors that through ebay would cost me a fortune.
AH HA. YES. WE VFD NOW.

I don't know why it couldn't take the 500mA from USB, but pulling out the variable supply I got from dad and hooking it up made [I]both[/I] screens power up with a tad under 300mA.
NOW WE CAN PROCEED. PROGRESS IS SWEET.

If you really need an uncommon value or high voltage your only real option is to go to a major distributor.

Funky little values like 1uf 50v or 47uf 16v in 4-6mm packages.

Those are pretty standard values, unless you absolutely need the correct package just get any old one that has the correct or close to capacitance rating, as for voltage equal or higher works fine.

They're tiny little low profile things.

Alright so I'd like to set up a small/medium beginner's lab and get into EE.
I've got a soldering station, third hand, small tools and cutters etc.
Could you fine gentlemen help set me up with a list of bits and bobs that'll get me started to go and fiddle with things?
I'm already neck-deep in my search for a ton of books on various subjects.
Side question: Could I cheap it out for the very start of my adventure with a cheap, small Dealextreme oscilloscope? I doubt I'll ever need really high precision measurements for a long period, so I'd rather not blow 3-400 bucks on one.
I'm in The Netherlands, but I'm sure my flagdog thing gave that away.
Don't forget a multimeter if you haven't one already.

Good point, I had one but I accidentally ran it over...
Okay, so since I [I]finally[/I] got that screen working, i've now ordered the breakout boards for the FM tuner, the MP3/ogg decoder, and the RTC module.
Now... we wait.

If you don't want to spend a lot on an oscilloscope you can get a basic old analog oscilloscope for about 20 - 60 euros if you look around.

Heat shrink tubing, alligator leads...maybe a breadboard for prototyping?
And I second the analog oscilloscope.
I just learned how I2C works.
Isn't it just awesome?
Whooo, forgot both the USB host [I]and[/I] the SD reader in my order. That'll wait til next paycheck. I can test the clock and the radio without them so meh for now.

IMO, One of the most powerful protocols for embedded systems.
[QUOTE=LoneWolf_Recon;42766679]IMO, One of the most powerful protocols for embedded systems.[/QUOTE]
Not really. It just depends on what you want to do. I2C certainly is the easiest to work with, but there are faster (SPI) and more reliable (CAN) protocols to work with.
So I live in a really old house and there's no ground wiring done. I am choosing between the Ersa Pico and Nano soldering stations. They are almost the same with the exception that Nano is ESD-Safe and a bit more expensive. Now I assume if there is no reliable ground in my apartament, it doesn't really matter if i use an "ESD-Safe" soldering station or not, right?

ESD-safe rarely has any impact on hobby level electronics.
I've never blown anything by touching or soldering it.
Followed some tutorials, got a VGA adapter working on verilog... :D

Had to order a avr programmer to flash my quadcopter, but they me a 10 pin to 10 pin cable instead of a 10 to 6.
Managed to ghetto fix it :D
[IMG]http://i.imgur.com/Kdqyoia.png[/IMG]
edit: reflashed quadcopter, now it wobbles like hell. lol
Wish I'd kept pictures of my ghetto mic extension cable. Made it from a 1/4" headphone plug adapter, an old stereo headphone cable, 2 binder clips, and a Reese's wrapper.
Worked great! However, some people couldn't understand me at all on vent, while others could hear me perfectly. Never figured out why that was.

You can melt anything by applying too much heat.
I've got an issue with programming a PIXACE chip.
It's a simple counting circuit and the counting works fine - but getting that over to a shift register/7 segment displays is a little harder. I need to (using flowchart programming, or BASIC) create an array of what numbers require what pins to be put high and which ones need to be put low - but I have absolutely no idea how to go about it.
