I figured out the full pinout to control the button matrix from an Arduino or other controller. Pinout and IC info here: <a href="http://www.straytechnologies.com/bliptronic-5000-hacking-full-pin-out-to-the-64-button-pcb/" rel="nofollow">http://www.straytechnologies.com/bliptr … utton-pcb/</a> Should be an easy task to get this running from an Arduino now! I'll try to get some test code posted over the next couple of weeks. Don’t know if you’re still working on this, but I worked out the IC’s and button PCB pinout here:

I've not had a chance to look at the bliptronic since last year (busy holiday season with travel back & forth across the atlantic). But I am finding myself revisiting it now. The diodes are to stop ghosting of button presses, so you can get true multi-touch. I'm still hopeful that there is some way to just directly plug (from the 16 pin header) this into something like the unsped shield (that has been altered to accept the 16 pin header) piggie backing on an arduino. That would open up the options greatly, and make it plug and play. But worse case scenario would be to go through and work out where all 32 traces are and wire them to the existing unsped shield the 16 buttons and 16 led's. I see some scary detailed soldering in my future. Hey Collin, interesting findings.

These trace back to the chips for me using a TI HC164 datasheet... but I haven't had luck shifting in values to the LED's. I haven't sorted out the purpose of the diodes across the board matrix, so maybe it has something to do with those, I don't know. Or maybe I'm using the wrong datasheet (i hope not). oh yah, for better reference, my pin numbers refer to pin 0 being the upper left pin in the first picture in your post here.

Got one for christmas explicitly to dissect. So far I have probed around the HC164 chips a bit and have the following pin assignments (my idea of pin 0 might seems strange here though): pin 0 gnd pin 5 gnd pin 9 vcc pin 14 A1 A2 hc164 pin 16 clk1 pin 17 clk2 hc164 pin 9 reset1 pin 8 reset2 HC164 hey JP- are you any farther with this?

Does anybody has a clue where the clock crystal is on this thing? I saw this silver long cilinder thingy next to where all the caps are ....but I'm not sure ..... it's marked X1 on the board... If i find the crystal I'll replace it by a precision oscillator so the thing can be tuned very low and high.... Thanx x Sylvie Hey Guys;…

The buttons are tactiles with a membrane cover which is cool. $50 for a 64 led button pad is what I am looking at.
