Usb Doomsday Device (Program Launcher)

Picture of Usb Doomsday Device (Program Launcher)
Hey There, Was looking around on thinkgeek.com a week or two ago and found the over priced"The Usb Doomsday Device" so i went ahead and had a look at some youtube vids and to my dismay all the Doomsday Device was, was a usb hub that generated a sound effect -.- And by looking at comments on the videos it was clear to see i wasnt alone on wanting this usb hub to also launch a program on your pc (or prehaps an explosion video?) of your choice.

So I went ahead and got the old noggin' workin' and I came up with the idea of creating my own version of the usb doomsday device on a very cheap budget. (actually only £9.88)

Step 1: Components

An usb game pad; £2 (ebay)
a key switch; £2.50
a push button; £1.99
a toggle switch;£1.99
a rocker switch; - (scavenged)
1 led; (i bought a 100 leds - 20 of each colour for £1.40 on ebay)
a project box; (free sample)
some  wire; (scavenged)
1 led holder; (free sample)
                                                         bringing us to a total cost of 9.88

you will also need a drill with drill bits, solder and soldering iron

Step 3: Fit switches

check all the switches fit and put them in tightening the necessary bolts
 
         now onto soldering

Step 4: Soldering

There is a schematic below for how to solder the components...

basically we're gonna go to the toggle switch, then the rocker, then the key and finally the push button. the led has its own circuit.

Put it all in the box and its done !!! now keep reading for the software part

Just finished my slightly varied version. :) Mine has 13 buttons but only 12 or in use atm and is very 'quick and dirty' version as i did it at 4am this morning and then finished touching it up after a couple hours sleep. Heres some pics, enjoy.

WOW neat idea, to use it for short-cuts to websites you like/use
Nice

amazing!

Thanks!

This is really cool and better looking than the ones available online and soooo much cheaper. Thanx for posting, instant fave! I think I'll build me one, a pirate fish one :) !!!!
DrWilson (author)  Zion_Sphere3 years ago
Thanks!! Post some Photos of how it goes!
This is cool, I was thinking of making one by myself, but I found this first! Thanks!

Thank You!

you could make it a password reset thing or something instead of having a reset disk
DrWilson (author)  monkeys983 years ago
Thats the idea, use whatever satisfies your needs

i like this doomsday device better than the one of thinkgeek. but there is one difference. i figured that it doesn't matter in which order you switch the switches, as long as the push button is pushed last (unless it is a locking push button). with tinkgeeks doomsday device you must switch the switches in a specific order (although this order is printet on the device) to activate it. but I'm definitely gonna make this!
DrWilson (author)  jvpernis3 years ago
Thanks, you could probably make this work is you knew arduino, which is something i Dont, post some pics and show us how you get on

i use this (CENSORED) with my gamepad(logitech gamepad f310)
duran19923 years ago
i want to make one or buy one of urs and put the code to make it get rid of every file on a computer that would be amazing
DrWilson (author)  duran19923 years ago
that would be possible, some sort of script I guess?!
gabry2073 years ago
damn, here in Syracuse (Sicily, Italy; not near NY) there's just one store that sells the components! Sometimes I think I live in Africa...

how much would this cost in America
Currently the pound to dollar exchange rate is about 2:1. Being that it takes about 2 dollars to equal one pound.
DrWilson (author)  scienceguy3 years ago
so $20 then !
DrWilson (author)  unanonymous3 years ago
Hmm good question but i dont know as im not from or familiar with the dollar
jvpernis3 years ago
I don't know arduino either, sure I'll post pics as soon as the components arrive. Butteeerm... do you think they ship the free sample project box to holland? I don't have a casing to put it in yet
DrWilson (author)  jvpernis3 years ago
errmm Okw might?
Wait, can you edit this and tell us how you connected the USB part? Thanks
I assume the USB was already attached as it was a USB gamepad to start with.
Then can you tell us where to solder all the switches to the gamepad?
DrWilson (author)  MediocreNinja4 years ago
you only need to do two wires to the game pad and then the switches in a parallel circuit

So technically, if we just had a usb cable, could we solder the switch/LED circuit to the data lines?
DrWilson (author)  MediocreNinja4 years ago
Hmm not sure to be honest but i don't think you could as it wouldn't be recognised by the software (xpadder) and i also think it needs a chip, but i suppose if you wired the data positive to the (+) wire ....
If your a coder you can code it. Or probably find some relatively easy driver writing software. And it goes to the green (date send) in a usb, not the power. Look for some usb 'ibles.

correct

if you really had secure material and thought you were about to be raided you could use this to launch something like kill disk and wipe your drive in seconds lol
DrWilson (author)  vampyredh4 years ago
lol slightly extreme but cool (hope terrorists arnet using this instructable for this purpose)
Oh don't worry. They use magnetic drive and just magnet them to wipe em.

errmm, what does it do??
DrWilson (author)  frodobot4 years ago
it basically launches a program on your computer like a document if the boss was coming or a explosion video so you can look like 007
Ah cool, looks like a real good project thats easy enough for me! lol

Where did u get the free sample project box?
DrWilson (author)  SRT4ever4 years ago
I will pm you a link as these guys will stop giving out samples if we all ask for one ;)
There Is also This http://www.maplin.co.uk/Module.aspx?ModuleNo=2355
DrWilson (author)  Sharlston Cat4 years ago
had a look at both, and as a matter of a fact I did consider putting both these in but, didn't as I wanted to keep a low budget
