May 8th meeting: well pumps, shade trees, and hot solar

There are a few things to share from this month’s meeting :

  • Folks compared notes about participation at RARSFest last month. The “non-commerical” aspect of Triembed folk’s participation at the next RARSFest is expected to be free. Whoever takes the lead on preparing for the next one can arrange this and get “just the right spot” for tables if they contact the organizers early in the process (4-6 weeks ahead).
  • Shane Trent passed a heavy duty patent law exam and is now a seriously useful resource for area developers wanting to invest in IP via the patent process. Congrats, Shane!
  • Paul MacDougal shared his setup for remotely detecting potential freezups of his well pump.
  • Chip McClelland showed an air temperature logging addition to his repertoire of park service tools being embedded at Umstead. This will allow the park staff to measure the cooling effect of newly planted shade trees.  Chip also passed around his full custom battery management board for folks to admire (built at Pete’s shop).
  • Pete described tests of the Silvertel AG103 Maximum Power Point Tracking solar powered battery charger board and a ten watt Ecoworthy solar panel being prepared for the “Little Library” Jeff Crews (of Splatspace) built and installed at the Durham Scrap Exchange.

December 12th Meeting: Better than Blinky

blinkinglightsfromgoogleimagesPaul MacDougal will talk about alternatives to the classic Arduino beginning program and shares this summary:
“Blink is a great first example for Arduino programming, but a really bad example of embedded programming. With 99.9% of its time spent in delay(), nothing else can happen. This talk will show how to rewrite blink in several different ways to allow it to play nicely with other functions.”

Join Paul and others at NCSU for the regular meeting. More details on the “at NCSU” meeting page.

August’s meeting included a project retrospective and demo of Brian Grawburg’s Raspberry Pi/Python driven traffic light simulation. This is part of a set of teaching tools Brian has developed for teaching Python to area youths at the Imagination Station in Wilson, NC Brian’s project is described in his article in the December, 2014 MagPi magazine (page 4) as well as on his project page.
