W88 at Southland Mini Maker Faire

Andrew+Kids5559Andrew and Jim represented Workshop 88 at the Southland Mini Maker Faire in Mokena August 27th.  That Faire is run by Jay Margalus, one of Workshop 88’s founders.

Andrew’s workshop for kids to create their own hand-dipped paint-film artworks was a big hit, with dozens of delighted artists taking home their masterpieces.  Foam balls were the canvas; a bucket of water was the studio.

spray_paint_1024AThe technique, invented by Andrew using a film of spray paint on a tub of water, was inspired by a similar approach he’d seen using nail polish.  Less-than-perfect results with the polish caused him to test and perfect the paint approach.  Results were spectacular.

The laser toys box was there, as TrayAndLizardsCq65vvhW8AADHjVusual, and its Escher lizards provided entertainment and education for many little (and not-so little!) hands.  Having the back sides of the laser-cut pieces engraved with three different patterns provided an additional level of challenge based on the 3-way tessellation as a 3 color map problem.  The laser engraved wording on what used to be the bottom of the tray used to be obscured by the toys.  With the addition of the new slightly smaller lower box, that old tray is now both a useful top cover and a convenient display card!

GearsCq6wHU5XgAAxTWC-600Jim’s UV-lit fluorescent non-round gears caused lots of folks to stop and take a look.  Their graceful turning, speeding up, slowing down, reversing and repeating mesmerized a few visitors.  Their stepper controller and Tiny85 processor mostly worked, but required some discreet wiggling several times to keep it all going.  The flaky solderless breadboard that hosted them has since been replaced by a much more reliable dedicated PCB.

Display+TabletHis hexagonal WS2812 individually addressable RGB LED wall display made its debut as an actual interactive device at this Faire.  Controlled by a 16-button app on an Android tablet, connected via Bluetooth to a cheap radio on the Arduino that runs the display, the display was fun to make dancing patterns with to music from a small sound system on the table.  Next upgrade will be a better drum pad app with velocity and aftertouch, and lots more controls.

Thanks and a tip of the W88 hat to Drew Fustini for some of these pictures!

 

Massimo’s great talk

MassimoRachelJimTwo members of Workshop 88 went to hear Massimo Banzi’s talk on Arduino, open source hardware and more.  The talk was part of Ge Garage’s Idea Week.  He gave some great stories of the philosophy, joys and problems of putting the Arduino out as open source hardware.

Among many other insights, he described how the fashion industry – with no intellectual property protection – made a lot more money than the entertainment and music industries with all their DRM efforts.  He told of the value of the many iterations of Arduino and how a primary metric of its success was the time between a new user opening the box and getting a useful result.  We learned it was named for a bar where they held many design meetings.  It was a great talk.

SignedArduino0243-300Rachel also scored some excellent networking time with Massimo, including connections that will be very useful in her upcoming trip to the Rome Maker Faire.  Jim brought home a newly autographed Arduino that had run the dollhouse at Rachel’s New York Maker Faire booth.

Automated Haunted Dollhouse part of Rachel’s Maker Faire exhibit

Pursuing her passion for making technology accessible to girls, Rachel Hellenga inspired a whirlwind project to automate a dollhouse.  After the smoke cleared, the one-room dollhouse she and Jim W and Bill P built was a miniature version of – and is now displayed within – the “Circuit Castle” she’s showing at the New York Maker Faire.  Read her Make Magazine blog post about it.

The Dollhouse Automation System powering it is a collection of small, cheap microcontrollers in a simple network allowing sensors (push buttons, motion detectors, light sensors, etc) in one part of the house to control actions (lights, motors, sounds etc) in another part of the house.

Here are some gory details of putting that system together.
