Thursday evening shenanigans

2013.May.2

On Thursdays, Ned comes in and either tears something down (for educational purposes) or fixes something up. I’m not sure what tonight’s activity counts as. He brought in a Big Mouth Billy Bass, and he and Rehana have been hacking into it, taking control of its servos. In the picture, you can see them causing [...]

Organ Donation

2013.March.13

Desk member Tom spent part of Tuesday happily hacking on some old relay boards salvaged from a defunct pipe organ. These devices were used to switch ranks of pipes in and out, but who knows what new purposes Tom will put them to?

Arduino Meetup Report

2013.March.11

The Arduino Meetup met at Jigsaw last Friday. The night’s project was to make strands of EL (electroluminescent) wire beat to members’ own pulses. Using the Arduino-compatible pulse sensor, available at pulsesensor.com, and the EL Escudo from SparkFun, members soldered, assembled and programmed all evening. One of the most difficult activities was attaching JST pins [...]

Teardown Thursdays Report 2013-01-31

2013.February.3

Ned’s current project is the old pipetting machine that’s been sitting around for a while. The pipetting stuff is gone, but what remains is a 3-axis machine that’s begging to be turned into some sort of CNC tool. All Ned has to do is figure out how to control it. He has determined that there [...]

2013.January.31

I occasionally volunteer with the Big-Brained Superheroes Club, an after-school program for young people. The other day, the kids were learning about binary numbers and I thought to myself, “Self, you should build an electronic binary-to-decimal converter, with LEDs and toggle switches. Yeah!” So I did. Well, building it was fun, and I could spend [...]

Leather Mask Workshop Report

2013.January.31

New Jigsaw member Tamara led a workshop on making leather masks, and I attended. The first step was creating the outline of the mask. After several iterations of sketching designs on paper and cutting them out, I ended up with something I thought was reasonable. I traced the design onto a piece of vegetable-tanned leather [...]

SCRoW Report 2013-01-16

2013.January.19

New member Rick worked on a little Arduino project, controlling a servo by analog joystick. First-time visitor Brian showed us a little sensor board that communicates with his phone via BlueTooth. Pretty cool! The usual suspects were there too. I worked on a little binary number toy for the Big-Brained Superheroes Club, where I volunteer. [...]
