Killer jazz, killer art–all at The Registry Theatre
I love it when musicians lean into their instrument. The Bernie Senensky Quartet lit up The Registry Theatre last Friday night. Bernie, himself (above), was positively wringing the music of Dave Brubeck out of this grand.
I went down to The Registry to check out work from the BOX artists that’s hanging in the lobby and stuck around for the jazz show later. Glad I did…
Art Allies show at WalterFedy
Oil on canvas – “Verge” – David G. White
Two great art forces came together on Thursday night: Art Allies connected with curator Suzanne Luke at WalterFedy to host the second show of original art from the region. This is another one of those everybody-wins situations where artists get paid rental for the 3 months their work hangs, any sales from the show go 75/25 artist/Art Allies, and WalterFedy gets some awesome and fresh art in their amazing space.
Arduino 101 meetup prep – day 9 – motor driving part 2
22May2009 – old stuff that may still be useful
Tonight’s fun centred on building the motor driver shield that Limor from Adafruit Industries kindly donated to support my Arduino 201 – Get Motorin’ meetup this Saturday.

Arduino 101 meetup prep – day 8 – motor driving part 1
21May2009 – old stuff that may still be useful
Motor drivers have arrived from Solarbotics and Adafruit Industries. Rejoice! Just in time for some midnight soldering (had an “oh-yeah…” moment when I remembered these are kits of the all-assembly-required type) before my Arduino 201 – Get Motorin’ meetup on Saturday. That’s the L298 Compact Motor Driver (CMD) shown above, generously donated to support our meetup by the good folks at Solarbotics (and there’s another waiting on the bench to be assembled).
Arduino 101 meetup prep – day 7 – VU meter needle gauge
11May2009 – old stuff that may still be useful
Another bit of scavenged gear to serve as an Arduino output device. Somebody please chime in here to tell me the official name for these type of gauges. This could be an interesting device to give an amusing analog measurement for something like your bug count, web server hit rate, outdoor temperature, number of unread xkcd entries, etc.

Arduino 101 meetup prep – day 6 – hacking toys
12May2009 – old stuff that may still be useful
Aaahhh, toys. Few things are sweeter to hack. I started at age 4 by smashing all my squirt guns open to get the pumps and hoses inside. Toys are great hacking fodder because:
- they’re cheap to obtain: trash, dollar store, Winners, garage sales, etc
- you can learn a ton from observing optimizations in their construction, which are usually due to cost sensitivity, but sometimes due to ease of assembly
- they often offer complex functionality (that would otherwise cost you an arm and a leg) that can be easily repurposed such as speech modules, gear motors, etc
The point of this post is to illustrate how to programmatically “push buttons” on a device using the Arduino.

Arduino 101 meetup prep – day 5 – optical limit switches
15May2009 – old stuff that may still be useful
Somebody was asking about limit switches today. We were talking about driving motors and my upcoming Arduino 201 – Get Motorin’ (May 23) meetup and he mentioned one of his applications required limit switches that signal a motor to stop running when something hits a certain limit of travel.
