Today is Pi Day everyone! Jigsaw celebrated in style thanks to Monica’s famous Pi Pies!
Member Pat also brought in celebratory Pi fruits and Pi ice creams.
In all the fun, we noticed that one of Pat’s fruits laid across one of Monnica’s pies along the diameter nicely, and we decided to do a little measuring. We found that the pie’s circumference was exactly 22 centimeters, and the fruit was just over 7 centimeters. For some irrational reason, we can’t seem to exactly measure the fruit, but Michael’s promised to bring in a higher precision calliper which might do the trick. In the mean time, here’s where we’re at so far with our equation:
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?
Jigsaw Renaissance was fairly buzzing with activity this afternoon. Ben & co. were feverishly preparing for this evening’s screening of a rough cut of Gamers. There was some cross-pollination going on between Team Elcano and RaaSIO. Scott was getting yet another 3D printer up and running. And those are just the folks I managed to take pictures of.
If you haven’t been to JR in a while, you really should come by. You might not recognize the place, things have changed so much in just the past couple of months.
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 to strands of EL wire. The delicate strands had to be stripped of their outer plastic shell and delicately cut open with an X-acto knife; then the tiny wires had to be carefully soldered to the wires on the JST pin. Everyone persevered until each person had an EL wire that beat to his or her own pulse.
Also, there were circuit board cookies! Don’t miss the next meetup.
Space is limited for Scott’s inaugural 3D printer workshop on Saturday. Over the course of five hours, you will build your very own 3D printer. Email Scott for more information and to reserve your spot. Don’t worry, there will be other workshops if you can’t get in this time.
In the video below, you can see one of Scott’s printers printing parts for the printers that will be built during the workshop. Crazy!
New Jigsaw desk member Scott is a 3D printing enthusiast. He brought in practically all the components of a Prusa printer, shown here laid out on his desk. Note in particular the extra-powerful NEMA 17 stepper motors, the Smoothie controller board, and the roll of <hushed tone>nylon 618</hushed tone>. (Oooooh.)
If none of that made any sense to you, come down and let Scott tell you all about it. He’ll be assembling those pieces into a working 3D printer, letting anyone who’s interested watch. He’ll also be leading workshops in which people will build their own printers and controller boards. Exciting stuff! Stay tuned for details.
