    Chelsea the Destroyer: AWESOME!!! Thank you for that link! *Why? Because metal lunchboxen make the BEST cases for just about any project!

    *Most local stores here sell only plastic lunch box crap - not metal like I grew up with. I fondly remember my “Road Runner” box I used to carry my tech-tools to college. Yes, was Wood Burning Tool; is soldering iron.

    *I especially like the first thing I found there: “Dia de los Muertos Lunchbox”.

    *Oh, we gonna have fun now, yass, we gonna have fun now!

    • Hard to do these days… but back when dinosaurs walked the earth, people used CRTs for computer monitors. A bit of work could reverse the wires going to the magnetic coils on the neck of the CRT and the image would then be reversed left to right. A small toggle switch mounted on the back of the case made it lots of fun… *
    • Now days, this hack is replaced with a screengrab and then use the image as desktop wallpaper. “Hey, my mouse doesn’t work! The cursor is frozen!”

    At my high school, the electronics instructor assigned everyone the taks of making an electric hotdog cooker. But later in life I found out far better things to do with electricity: GLOWING PICKLES! https://www.youtube.com/watch?v=aab8VjzuXyM

    Never mind! Just re-read your writeup and see you did just that - the signals are reaching the processor. Good job.

    I could not tell from your writeup if you have verified beyond all doubt that the front panel buttons are still working. That is, when you look at the switch matrix with a scope or meter, does something actually change when the buttons are pressed? I mention this because the switches themselves are by far the most likely failure mechanism - not the processor. With mechanical switches, the contacts often get corroded and need cleaning. With membrane switches, the membrane pads often get dirty and no longer work.

    One common hack for these things is to change the clock frequency. In particular, greeting cards that have sound chips inside so that they play some silly voice sounds are easy to do. Most of these use RC oscillators ($cheap) so look around for a likely RC pair. Then while it’s playing, lick your finger and touch around on the resistor. Often, you will decrease the effective value thus raising the frequency producing “Donald Duck” like noises. Now measure the resistor value and substitute small poteniometer either across it or in place of it. Tweak until it makes you laugh.

    “we SparkFunions got to hear about the 6 foot chaotic water wheel Nathan and his buddy built in their dorm room; complete with 55 gallons of water” Hey, hey, HEY!! We want to hear (and see) all about that!!!
