Has anyone used this Happ controls Part Number 64-0053-00 on their juke? If so how did you hook it up. I read in one post on a different site a guy used part of an old keyboard. Any help would be appreciated.

I recieved the panel today, it has a 9 pin connector on it and its matrixed. Has anyone here hacked a matrixed pad like this before?

It looks a lot like the pad at http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=124569 . If it is the same pad, the matrix is listed on the data sheet at http://www.jameco.com/wcsstore/Jameco/Products/ProdDS/196171.PDF . Since it's matrixed, the ideal interface for it would be a keyboard hack. Hey, there's actually a situation where a keyboard hack is better than an encoder!

that is the keypad that I have. Thanks a ton. One quick question, how would I go about hooking up the keyboard hack to the keypad? I have a hacked matrixed keyboard that I bought from someone and i have a sheet with the matrix on it. I see the pin out on that link you gave me for the keypad, but I have no clue as to what wires from the keyboard should go to which pins on the keypad.

Do you mind doing a write up on how you got it working? I plan on building a jukebox and wanted some kind of number pad like that but would have no idea how to get it working.

redcoats · « **Reply #6 on:** April 09, 2005, 04:34:11 am »

There is no left or right arrows. I wouldn't know if that would be good to use?

rob1234 · « **Reply #7 on:** April 09, 2005, 02:30:50 pm »

I have 2 on order from happs. The triangle low profile.

rob1234 · « **Reply #8 on:** April 09, 2005, 02:43:40 pm »

Here is how I got it working:

Supplies-
1) Hacked matrixed keyboard (I bought it from someone from these boards for $17)
2) Keypad Number 64-0053-00 $18 I think
3) Some wire
4) a jumper harness to a motherboard (free I took it out of a busted hp vectra computer.

What to do.
1) I went to this site to get the diagram of the keypad. http://www.jameco.com/wcsstore/Jameco/Products/ProdDS/196171.PDF

2) I ran 4 wires from one side of the matrix for the keyboard hack to the first 4 of the 9 pins on the bottom of the keypad. ( the web link above tells you which pin is #1)

3) I ran 4 other wires from the other side of the matrixed keyboard hack to pins 5,6,7 and 8.

4) You will need to refer to a diagram for your matrix on the keyboard to make sure you are not making combinations for non existant keys.

5) I plugged in the keypad using the keyboard port, and selected key map in virtual music jukebox and went through and reasigned each key to represent what it displayed. If you are useing this pad, you will almost for sure need to have a program that allows you to remap your keys. I am going to hook up an usb keyboard since this hack takes the keyboard port on the computer.

This may sound a little confusing, but I think you can figure it out once you mess with it. I will try to help anyway I can, just pm me. Otherwise Chris on this board was a lot of help.

Thanks for the write up Rob.

This looks pretty cool, thanks for the writeup. Can you take this apart and physically turn the up and down buttons to make them left and right?

No you can't take it apart. The buttons are not detachable. I have some pics to show you exactly what it is, and how it is hooked up. I like it the way it is. I use the 2 arrows on it for the volume control. This pad does have the "2ND" button which should be able to be used as a shift key. If you can get it to work, the vertical buttons have the horizontal ones on them for the shift function.

I would imagine that Shift is seen like any other button and it's up to the software to treat it like a Shift key.

rob1234 · « **Reply #14 on:** April 13, 2005, 10:42:15 am »

I didn't try to get the shift button to work, I am not planning on using it.

It looks like the face is just a mylar overlay. Does there appear to be a way to remove that outer frame and swap out the overlay, or is it permanently attached?

--Chris

rob1234 · « **Reply #16 on:** April 13, 2005, 12:30:17 pm »

I have removed the board from the back once, and the overlay is attached to the rubber buttons, so I don't know how easy it would be to switch it.

Chris · « **Reply #17 on:** April 13, 2005, 02:22:50 pm »

Too bad... it would be perfect for all sorts of things if we could print up our own overlays for it...

On the other hand, a self-stick vinyl overlay would probably work....

This is what my control panel looks like. I will be posting pics of my juke so far in the project section if you are interested in checking it out. The blue buttons will be for navigating left and right through the cd's within my virtual music jukebox.

Cheers... this writeup rocks. Im about to purchase one of these keypads myself in the next few days. Similar type of setup, but just adding a 4 extra illuminated buttons for random, skip, mute and pause on the front panel. Keep us posted with pics
