Lighting Control Upgrade!

IMAG3517In an effort to make the lighting control system more user-friendly, the original board-mounted switches have been replaced with a laser-cut zone map! Instead of looking up which zone number corresponds to a particular bank of lights, each location is now identified by a green LED pushbutton.  You can read more about the lighting control system and how it’s been evolving on our wiki: http://wiki.milwaukeemakerspace.org/projects/mmlc

Brown Dog Gadgets on Kickstarter

Kickstarter

Joshua is a recent addition to Milwaukee Makerspace, and as we mentioned before, he runs a kit company called BrownDogGadgets. Well, the latest on Joshua is a Kickstarter campaign he’s running… and yeah, did we mention it’s over $71,000 now!?

He originally had a goal of $5,000 but the backers showed up in force to support his Folding USB Solar Cell project, and even though it’s been cloudy and raining all week here in Milwaukee, it’s all sunshine and smiles at the success of the campaign so far.

Check it out on Kickstarter if you’re into solar power, got an iPhone you need charged, or just like brown dogs. :)

Builder’s Night Out – September 29th

In addition to the usual hackery and makers working on their electric cars, Bret fired up the forge again last night.  Rich turned some horseshoes into hangers, Adam flattened a steel rod, and Royce folded a metal bar.

In preparation for BarCampMilwaukee6 (this weekend!) Royce and I have been mass producing circuit boards for a “learn to solder” class we’ll be holding.  The boards are 1.5″x1.5″ square and include a battery, two resistors, traces in the shape of our logo, and two red LEDs for eyes.  The copper traces were tinned using “Tin It” to prevent oxidation and make it easier to solder.  We’ve made 65 of the “tie pins” so far and the project gave us an opportunity to tweak our methods for PCB etching.  We prefer etching with ferric chloride, but muriatic acid and hydrogen peroxide are looking more attractive as they’re cheaper chemicals, can be obtained locally, and etch much faster without heating.  Also, red Sharpie markers seem to work really well at cleaning up traces with the muriatic acid solution.  Specifically red, not sure why.
