Step 4: Test, Deploy

Now here's the fun part: plug your apparatus into your PC, and see what it does.

In most cases you should be able to use your new device right alongside your "normal" keyboard, as long as you've got the ports (mine is USB, but a PS2 would work, too).

If the test is successful, package it up and call it complete!

I glued an F1 key to my device (from the donor keyboard, of course), and even though it  will be stashed away inside my kiosk and never be seen, I like the idea that the F1 key is in there, silently advertising its silly purpose...

Thanks for reading!

Can you make multiple out of one keyboard
<p>I've bookmarked this instructable and may give it a shot one of these days. Thanks!</p><p>I have (and dearly love) my old IBM Model M buckling spring keyboard from the 80's. I'm excentric, I guess. I was idly Googling whether there was a 1-key keyboard out there that I could map to a Windows key and have it off to the side somewhere.</p>
Awesome instructable man! Now, only to have an &quot;Any-PC-BIOS-key spammer&quot; for those stupid HP BIOS screens that want you to press escape. Also, you could try searching for a firmware update that has the ability to turn off the keyboard.
I love this! <br> <br>I do worship video for two different churches in the course of a week. Each uses a different software. The one at Church A moves from slide to slide with the arrow keys. Very convenient and ergonomic. The software at Church B uses F9 and F10, which are clumsy and wearing to use, so I end up resorting to the mouse (ugh). <br> <br>This would be perfect! One little box with buttons that just do F9 and F10 (labeled Next and Previous) that I can hold in my lap while I sit back in comfort. <br> <br>I'm going to dig out an old keyboard as soon as I get home!
I just want to be the first to say that when I saw the picture, the first thing I thought of was this:
my favorite
Any OS run with 1 button ???
The Macbook Wheel!<br><br>http://www.youtube.com/watch?v=9BnLbv6QYcA
the Mactini<br><br>http://www.youtube.com/watch?v=gw80nMPv1Wc
I was thinking about tha same image too :p
&iexcl;&iexcl;&iexcl; OH.. YES !!! The essential keyboard for ANY Windows since 3.1
Hah! Spoken like a fellow MS user ;) wonder if the one in the pic really works? It certainly <em>could</em>. Also might help with the carpal tunnel caused by the constant stretch to accomplish the MS three-finger salute...
OK - I can really use this. <br> <br>I am a mechanical designer and run CAD programs all day with my right hand on the mouse and my left hand on a SpaceNavigator ( http://www.3dconnexion.com/products/spacenavigator.html ). Often have to reach over and hit the F8 key to reset a view. Going to make one of these had have it right were I can hit it with my thumb without taking my hand off the SpaceNavigator. <br> <br>Build it - they will come.
You could use AutoHotkey (autohotkey.com) and a simple script to redefine one of the extra mouse buttons to F8.<br><br>One line script;<br>Xbutton1::send {F8}
All combinations of mouse buttons for a three button mouse are already utilized by commands in the CAD software. <br> <br>Is there a mouse available that has extra buttons?
does your wheel have a click feature? do you use it? some mice have side buttons that are programmable http://tinyurl.com/68xuaa9
logitech m305. side scrolling buttons and middleclick too, for about 15 bucks, and it's wireless. works great in linux too
How about 13 buttons?<br><br>http://www.logitech.com/en-us/mice-pointers/mice/devices/7244<br><br>If you're on OS X, I highly recommend ControllerMate, which allows you customize the behavior of almost all mice, keyboards, and joysticks (esp. ones w/o Mac drivers).
Nice one dude!<br>tnx!!!
@mtkraabel<br>You might actually benefit from something like this:<br>http://store.razerzone.com/store/razerusa/en_US/pd/productID.169418900<br>17 buttons. &quot;MMO optimized&quot;, but I use a DeathAdder for work (non-gaming) simply because it's more comfortable &amp; works better than other mice I've tried. I have 5 buttons (including the mousewheel), and sometimes I wish I had a few more so I could bind them using AutoHotkey. I don't recommend razer's keyboards, but I've loved their mice.<br><br>You could also try something like this, but I think it looks awfully-designed:<br>http://www.warmouse.com/<br><br>Good luck!
Lots have two more buttons.<br><br>http://www.microsoft.com/hardware/en-us/p/comfort-mouse-4500/4FD-00006#n<br><br>In autohotkey the buttons a Left, Right, Middle, Xbutton1 &amp; Xbutton2.<br><br>Also many (incl the above) come with software to program the buttons if you don't want to use autohotkey
Software wouldn't do anything, this is during the bootup process, well before the OS is even running.
I was talking about mtkraable's issue re two handed CAD control &amp; pressing F8.<br><br>Sorry for the confusion
oops, missed that your comment was a reply to a comment. thought it was straight comment to the article. my bad.
Or a foot switch.
Definitely. They sell foot switches that are basically just pressing the &quot;up&quot; or &quot;down&quot; keyfor scrolling text, or other &quot;keys&quot; for advancing powerpoint slides, etc.
Hi folks! Just thought I'd pass this along because it's pretty entertaining: Thank you to Mike Nathan who posted this project at HackADay: <a href="http://hackaday.com/2011/05/29/fixing-post-errors-with-a-single-key/">http://hackaday.com/2011/05/29/fixing-post-errors-with-a-single-key/</a> ...I'm enjoying how angry this made about half of the people who left comments, and how the other half of the folks are defending my silly hack...
Forgive my ignorance, but this would be possible to do with the enter key, right? As long as I soldered the correct connections?
Absolutely. Of course, I assume you'd want a &quot;real&quot; button (because something that sends &quot;enter&quot; all day is nearly as silly as something that sends &quot;F1&quot;), but yes, any button (or combination of buttons) can be triggered by correctly shorting the connections on the circuit board.
Couldn't you just have stashed the old fan someplace out of the way but left it plugged into the motherboard, and then wired the power wires for the new fan in parallel with the existing ones? Use the old fan to blow air over something else in the project that needed cooling?
Lame excuse for the build but good execution, there must be a reasoning for a keyboardless kiosk and i would imagine you would want to keep it clean so not really sure why add the button with so many more efficient ways to fix the real issue ie rewiring the fan, sending a signal to the speedometer or heck removing or getting a different powersource for the fan.
Why didn't you fix the real problem? Either getting a fan with speed signal or connecting some +2V wire to the speed signal pin.<br>Seems way easier.
Absolutely! Except I didn't have the item on hand, and did not want to stray from the &quot;spend no money&quot; mantra, and I didn't know how to fool the motherboard... wish I'd asked you sooner!
You don't have to fool the motherboard, you can give it the real RPM signal. Connect a wire from the collector pin on the transistor right before the motor coil in the fan, to the 3rd pin on the motherboard header for RPM. 4th wire isn't needed to get RPM, it is the PWM control line.<br><br>Another possible option is to edit the bios, if there is an editor you can find that handles the core version and brand (Phoenix, Award, AMI, etc.), there is probably a setting that is hidden from the user interface, although there might even be a key combination that will get you to full control page when the system POSTS prior to booting, but it is harder to find this info as it can vary.<br><br>A note to other people: A constant *on* key can cause very weird behavior on some OS (including windows) depending on which it is, or constant beeping, or especially with PS2, loss of use of the other PS2 connected input device as the buffer is full from the /stuck/ key signal.
you mean like that BEEPBEEPBEEPBEEPBEEP i get when i've fallen asleep face-down on the keyboard? <br> <br>i can see it.
MUCH wiser solutions, Kudos!<br><br>I did test the F1behavior before I went down this silly road, but I can see how the stuck key syndrome could truly bork things up in other circumstances...
Failure of battery, that keeps the BIOS on hold, could also be the problem...
While a failed battery could indeed also cause a F1/F2 pause, in this case the message actually said &quot;CPU fan&quot; and I had no reason to disbelieve.

great writing style.. i am going to glue the a n y keys to my usb to see if i can get my grandkids to press it them.. i know some of the end users at work would try them..
In the line of 'fix the fan' comments, it would probably have worked to unscrew the old fan from the old heatsink/fan assembly, and attach it to the new, lower-profile heatsink.<br><br>Now, this assumes that the new fan/sink can shed enough heat to reliably run this thing.
On Some Boards, you just can disable Stopping because of a missing Keyboard.<br>Look in the BIOS for something like &quot;HALT ON&quot; or POST-Errors.
And now for something completely different...<br> <br> You have a great writing style and a lovely sense of the ridiculous. I laughed out loud a couple of times. It's very enjoyable (and much easier) to read a well written piece of work. Thanks.<br>
Cool instructable dude!!! Never even thought about trying this with a kby. I'm gonna go try this for my custom gaming kby. Shot!!
Very innovative solution, obviously plenty of lateral thinking is happening here.<br><br>I can see a few uses for the keyboard hack by ripping out keys to make a convenient mini keyboard, but actually keeping the key depressed can be fraught with problems. I would probably prefer to go with the hardware solutions to resolve the problem - ie hotwire the tranny. <br><br>Have you been able to check for any performance issues post hack? I would expect hammering the buffer with kb signal constantly will grab plenty of CPU cycles and eventually slow or completely lock the system. Also if you have a secondary problem with the system after POST then you are going to miss it.
everyone i am soon going to make something you will all like
Sounds good.
