Introduction: 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)

 **********************************USB CONTEST ENTRY*************************************
                                                               PLEASE VOTE! :)


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 2: Mark Out Holes Then Cut Em'

First we need to take the lid of our project box and mark out where to drill for the switches 
then drill :)

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.

Step 5:

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

Step 6: Software

Now we need to set-up xpadder (download below)

Map a new controller;
go to the buttons tab;
activate all the switches and press the button;
this will make the software recognise the controllers button;
save and close the window;
now click on the grey or green button;
set it as a key combination;
now go to the file you want launched and copy it then create a short-cut somewhere;
now right click the sort-cut and click properties;
now change the short-cut key to the same as the one you made in xpadder.

                      try it out!

Step 7: Thanks

thanks for reading this instructable please comment, and vote for me - in the usb contest



thanks
 
 you could add a 4 port usb inside but I didn't need this

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!

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_Sphere2010-09-02

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!

author
DrWilson (author)Asian Invasion2010-09-01

Thank You!

you could make it a password reset thing or something instead of having a reset disk

author
DrWilson (author)Jo-dan2010-08-19

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)Spectre2082010-08-16

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

techboy411 (author)2012-12-31

i use this (CENSORED) with my gamepad(logitech gamepad f310)

duran1992 (author)2010-11-25

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

author
DrWilson (author)duran19922010-12-01

that would be possible, some sort of script I guess?!

author
gabry207 (author)2010-09-29

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...

unanonymous (author)2010-08-14

how much would this cost in America

author
scienceguy (author)unanonymous2010-09-17

Currently the pound to dollar exchange rate is about 2:1. Being that it takes about 2 dollars to equal one pound.

author
DrWilson (author)scienceguy2010-09-17

so $20 then !

author
DrWilson (author)unanonymous2010-08-15

Hmm good question but i dont know as im not from or familiar with the dollar

author
Spectre208 (author)2010-08-17

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

author
DrWilson (author)Spectre2082010-08-17

errmm Okw might?

author
MediocreNinja (author)2010-06-18

Wait, can you edit this and tell us how you connected the USB part? Thanks

author

I assume the USB was already attached as it was a USB gamepad to start with.

author

Then can you tell us where to solder all the switches to the gamepad?

author
DrWilson (author)MediocreNinja2010-06-19

you only need to do two wires to the game pad and then the switches in a parallel circuit

author
MediocreNinja (author)DrWilson2010-06-19

So technically, if we just had a usb cable, could we solder the switch/LED circuit to the data lines?

author
DrWilson (author)MediocreNinja2010-06-19

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 ....

octopuscabbage (author)DrWilson2010-07-20

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.

author
DrWilson (author)tylerfrankling2010-06-19

correct

author
vampyredh (author)2010-06-27

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

author
DrWilson (author)vampyredh2010-06-27

lol slightly extreme but cool (hope terrorists arnet using this instructable for this purpose)

author
octopuscabbage (author)DrWilson2010-07-20

Oh don't worry. They use magnetic drive and just magnet them to wipe em.

author
frodobot (author)2010-06-17

errmm, what does it do??

author
DrWilson (author)frodobot2010-06-17

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

author
frodobot (author)DrWilson2010-06-19

Ah cool, looks like a real good project thats easy enough for me! lol

author
SRT4ever (author)2010-06-18

Where did u get the free sample project box?

author
DrWilson (author)SRT4ever2010-06-19

I will pm you a link as these guys will stop giving out samples if we all ask for one ;)

author
Sharlston Cat (author)2010-06-17

There Is also This http://www.maplin.co.uk/Module.aspx?ModuleNo=2355

author
DrWilson (author)Sharlston Cat2010-06-18

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

author
Sharlston Cat (author)2010-06-17

Which GamePad On Ebay An Ps2 Remote

author
DrWilson (author)Sharlston Cat2010-06-18

errm yhea as long as it has a usb connection ;)

author
Sharlston Cat (author)2010-06-17

frankie have a look at this its from maplin Here It IS: http://www.maplin.co.uk/Module.aspx?ModuleNo=37319

nadav (author)2010-06-14

cool, but you can get free samples of key switches from here http://www.tycoelectronics.com/catalog/feat/en/c/15856?BML=10576,16354,13873

author
DrWilson (author)nadav2010-06-14

Thanks, just sent off for one now, lets hope it comes :)

author
nadav (author)DrWilson2010-06-14

No Prob. It shipped to me, Im in Canada.
