Mystery Unboxing

By
We recently received our second order of Surprise Boxes and Display Assortments from Electronic Goldmine, and again we made a group activity out of unboxing and sorting the parts. Afterward I combined all the sorted containers from previous unboxings, both Freeside's and my own, and started categorizing things.



The take this time was similar to last time. We got a lot of VFDs from the display assortments, which we can't use right now due to lack of a good cheap easy-to-reproduce 30-40V AC power supply, but those will be much fun later. We went with the "Super" (medium size) surprise boxes this time, to get more densely packed smaller components and less larger sparse items like the security hardware and R/C cars for last time. The choice parts this time included some high voltage relays, two-prong AC outlets, a bunch more 96x64 LCDs, a few dozen dual RJ45 jacks, some 10-segment LED bar graphs, and a lot of nice trim and dual-log pots. The bulk of the order was once again capacitors.

We are going to take a break before the next order, probably 2-3 months, so that they can cycle through their stock and hopefully provide a bit more variety next time.

A Capacitive-Touch Janko Keyboard: What I Did at the 2017 Georgia Tech Moog Hackathon

By
Last weekend (February 10-12, 2017) I made a Janko-layout capacitive-touch keyboard for the Moog Werkstatt at the Georgia Tech Moog Hackathon. The day after (Monday the 13th), I made this short video of the keyboard being played: "Capacitive Touch Janko Keyboard for Moog Werkstatt" (Text from the video doobly doo) This is a Janko-layout touch keyboard I made at the 2017 Moog Hackathon at Georgia Tech, February 10-12. I'm playing a few classic bass and melody lines from popular and classic tunes. I only have one octave (13 notes) connected so far. The capacitive touch sensors use MPR121 capacitive-touch chips, on breakout boards from Adafruit (Moog Hackathon sponsor Sparkfun makes a similar board for the same chip). The example code from Adafruit was modified to read four boards (using the Adafruit library and making four sensor objects and initializing each to one of the four I2C addresses is remarkably easy for anyone with moderate familiarity with C++), and ...

What to Do With a Stack of Picture Frames?

By
When You Have Too Much Free Stuff! Our newest member Raul got his hands on a stack of about 40 picture frames that were being junked. On a general note Freeside tends to discourage large piles of objects randomly appearing as it tends to collect in corners. Raul got permission from our projects team with a time limit of a few weeks. In this case unnecessary, as the membership more or less attacked the pile of boxes and rapidly rendered them into things. Unfortunately starting off all the frames looked something like this: Not terribly useful. We don't even have any idea who these guys are. After a few passes through the planer, however, we get something like this: A perfectly good picture frame useful for stuff. First idea was to push a couple of these through a the laser cutter. Concept good, aim.... Aim was a little off. Also we had just rebuilt the laser computer and electronics so there were a couple of kinks to work out in CamBam's post processor: &nbsp ...
