2013 Annual Member Survey Results!

Feedback and constructive criticism can be great tools for planning and managing any sort of endeavor.  Gauging the interests, concerns, and opinions of our group can help us make better decision on how to spend time and money as well as working with each other and the community.  Last month we asked our members to take a survey and share their thoughts with us.  Why do people come to Milwaukee Makerspace?  What do they do here?  What would they like to see more of?  What can we do better?  44 members responded (or about 39% of the total group) and after spending some time slaving over spreadsheets, we published the results.

Two of the biggest questions we asked survey-takers were: 1) What do you come to Milwaukee Makerspace for? and 2) What is important to you?  The following results can be found in our 19 page report, available for download here:  http://wiki.milwaukeemakerspace.org/_media/2013_annual_mms_member_survey.pdf

Staying Stocked Up

The idea was simple: make something to help keep track of our supplies so we know when we’re running low on the essentials.  After weeks of kicking the idea around and various rough doodles, this project finally took shape.  Two days after the first cut on the laser cutter, it was complete.


Made from multiple layers of acrylic, cardboard, and wood, the “Milwaukee Makerspace Consumables Super Analog Status Board” is a clipboard-sized device with nine sliders installed in enclosed slots.  Sliding the tabs right displays more green to indicate “full” or “lots” and sliding left reveals the red acrylic below to indicate “empty” or “low.”  The user can carry the board around the Space with them as they check on supplies and when done, a large hole centered at the top allows the board to be hung up and displayed on a wall.

The hardware holding the whole thing together can be loosened and the layers disassembled.  The cardboard insert that the text resides on can be swapped out should we decide to change the list of items we want to keep tabs on.  The supplies being tracked currently include:

  • Toilet Paper
  • Paper Towels
  • Hand Soap
  • Welding Gases
  • Welding Wire
  • Propane
  • Soda
  • Duct Tape
  • Painter’s Tape

A digital version may or may not be planned for future release.

Remote-Controlled LED Room Lighting

This gallery contains 4 photos.

My apartment has sub-par to poor lighting.  Combine that with our lease’s “no painting walls” policy and you’ve got a one-way ticket to Drab-ville.  Many moons ago I planned to replace the over-cabinet lighting in our kitchen with RGB LEDs controlled by Arduino, but I never found the motivation to actually do it.  Then one […]

Milwaukee Makerspace Moves It

Milwaukee Makerspace’s new building at 2555 Lenox St. used to be the home of a data center and had two computer rooms, each with a raised floor. On Saturday, 10/27/12 several members got together and removed the last of the tiles and posts.

Roughly 1,000 tiles, each weighing 18 lbs., were removed from the west room and stacked in a dumpster for recycling. The west room took about 90 minutes to complete with 7-10 people! Thanks to everyone who turned out and we’ll be posting more news as the building comes together!

Random Find: The Avago/HP HDLG-2416

Anyone who’s ever visited Makerspace knows that the ‘Library’ is home to tons and tons of stuff.  Component parts, IC chips, belts, pulleys, batteries, etc.  Occasionally I lose myself in there for a few hours and just explore the shelves.  This is a post about one of my more interesting discoveries.


I came across a whole bag of these in the LED bins.  They’re 1″ wide, four-digit alphanumeric displays.  Each character consists of a 5 mm tall, 5×7 LED dot matrix display.  The device comes complete with on-board RAM and an ASCII decoder capable of displaying up to 128 different characters.  It’s even possible to dim the brightness.  I’m also partial to the color green.

The major drawback I’ve found is the number of pins required for use.  The thing has seven data pins and the extended features for writing/reading/displaying require a ton of connections.  I used all but four of my Arduino Uno’s I/O pins while tinkering with it.  You’re probably better off using a LCD display or something with serial data support, but these are still small and numerous in our ‘Space so they’re worth toying with.  Also there’s been a few other people who played with these and posted their findings online. I’m seriously considering building a small desk clock around one or two of these in the future.

If you’re interested in using one of these displays on your next project, I’d suggest reading the blogs by these fine folks here:

Magic Mirror Theater Prop

My sister is a Theater Manager at the Patel Conservatory in Tampa, FL.  About two weeks ago she texted me and asked if I could make her a prop she needed for an upcoming production.  “How keen would you be on making me a mirror for “Beauty and The Beast,” she said.  “They want a mirror that lights up and sparkles like the one from the movie.” Even with limited experience just tinkering around, I knew I could do something fairly easily, so I agreed and got to work.

I combined two different circuits (a 555 timer to flash and a RC circuit to fade) and built a wooden frame with acrylic plates for the front and back.  The wood and plastic were CNC-milled, then sanded and painted before the electronics were installed and glued into place.

The result was a fairly decent-looking, shiny, light-up hand mirror with a small thumb button on the right side that flashes 16 bright green LEDs when pressed.  It all runs off a single 9-volt battery and the back can be unscrewed to replace it should it ever die.

Total build time from start to finish was probably close to 15 hours over the course of one week.  The play was Thursday, July 19th and from what I’ve heard, it was a great success.  I’ll add pictures from the performance if I get some.

Laser Cut Safety Lock-Out Tags

Lock-out tags are used by factory workers to clearly identify broken or damaged equipment.  Milwaukee Makerspace is no exception.  A set of stop sign-shaped, 3″ wide, 3/16″ thick, red plastic tags have been created with the words “STOP – NEEDS REPAIR” in bold, white letters.  Tags are hanging over the first aid file cabinet by the light switches in the Workshop.  If you find a machine is out of service, please zip-tie a tag to the machine, preferably over its ON/OFF switch so people can easily spot it and refrain from using a potentially unsafe tool.
