Solar lights on the Workshop 88 sign!

We’re always looking for ways to make getting to Workshop 88 a bit easier to discover. Recently, one of our members donated and installed light string on the sign post outside of Workshop 88.  These lights are battery-powered, and the batteries are recharged daily by solar cells.  If you arrive to Workshop 88 after the sun has set these lights will help you know you’re in the right place!

Member projects: Thingiverse remix

One of our new members, Josh, has been making great use of the 3D printers at Workshop 88. He had a headlight for his bike that he wanted centered on the handlebars. So he took the Blackburn Flea Bike Light Handlebar Mount file on Thingiverse and remixed it to fit on his bike. Here is his remix – the photo at the top shows the finished print.

Member project: Crowd-sourced science

Animation of some preliminary results from the Steelpan Vibrations project on Zooniverse.

One of our members, Andrew Morrison, has a citizen science project running on the Zooniverse website.

The project is called Steelpan Vibrations and is a project looking at understanding how Caribbean steelpans (sometimes referred to as steel drums) work to produce their characteristic sound. What he has done is made high speed videos of the waves that go across the steel pan when it is struck by a player. The problem is that there is no easy way to analyze the video frames to get quantitative data. The project asks for people to go to the website and mark individual frames so that they can be aggregated together for analysis later.

There is a blog where details about the research are discussed regularly, and you can also follow Andrew on twitter where project updates are regularly posted.

Member projects: Building a night sky observatory!!

One of our members, Steven Sagerian, has a passion for astronomy and astronomy education and outreach. He has been working on building an observing site outside of the Chicago suburbs in a dark location – and now he has a GoFundMe set up to make this a reality!

Steve also has designed a solar panel system for charging batteries to run the observatory. You can see the solar cells in the photo on the GoFundMe site, and he also has a page dedicated to the design and construction of it.

Mustard etching?

We’ve been playing with the etching of metals with our laser cutter at Workshop 88. One of our members discovered a mustard-etching method and tested it out last night during the weekly open house.

The results are pretty great for a first attempt! Expect more detail to come in future posts – but if you want to know more, please come to our open house meetings every Thursday night!
