Workshop Details:

Bring your soldering iron and hand tools to this workshop to learn how to create sculptures that actually do something!
In this workshop, we’ll be building a firefly together with custom jigs, brass wire, and LEDs.
If you’ve ever wondered how these beautiful sculptures are created, now is your chance to learn.

Instructors: This workshop is taught by Jiri Praus, Kelly Heaton, and Mohit Bhoite, all of who will be in different time zones at the time of this workshop

Jiri Praus's day job is being a full-stack developer, while at night he is an enthusiastic electronic artist combining brass, wood, acrylic, and plastic into unique electronic devices and free-form sculptures. His intricate use of 3D printed fixtures, jigs, and templates to create three-dimensional electronic circuits, sculptures, and devices is an inspiration for thousands of people around the globe.

Kelly Heaton is a mixed-media artist known for her intersection of electronics and visual art. Her creative use of technology evokes humanity’s divergence from nature, meanwhile demonstrating the power of electricity to give profound insight into life on Earth.

Mohit Bhoite works as a senior hardware engineer at Particle, where he designs and builds their flagship IoT products. He is also an avid maker who dedicates his personal time to building free-formed electronic sculptures primarily out of brass.

Hi Kelly, would it be possible to share your PDF walkthru of your firefly that Mohit shared? It would be super helpful - thanks!

Its available under the files section above!

Any way to still get into this workshop?

@Janet Either a brass rod or wire will do. Ideally around 0.8mm in diameter. 

  Are you sure? yes | no

Janet wrote 11/03/2020 at 21:41 point

Thanks! Looking forward to this very much. Cheers.

Hi! Excited for this workshop! Does the copper/brass wire need to be bare (i.e. not "non-tarnishing")?

  Are you sure? yes | no

Kelly Heaton wrote 11/06/2020 at 17:00 point

Hi Sophy! I'm so happy that you are joining us. In order to solder brass or copper the metal does need to be "bare," however, you can use sandpaper to remove any surface coating -- whether it be a protectant or oxidation.

  Are you sure? yes | no

Sophy Wong wrote 11/07/2020 at 00:35 point

Thank you! Excellent, I found some uncoated wire in my stash :) Looking forward to it!

  Are you sure? yes | no

Kelly Heaton wrote 10/30/2020 at 14:12 point

Hi Janet! Brass rod is not necessary, but it would be helpful because it's rigid and enables you to build architectural forms that are hard to make with wire (because it's "bendy"). Let us know if you have other questions. See you at the workshop!

  Are you sure? yes | no

Janet wrote 11/03/2020 at 04:56 point

Ah great - thanks very much! 

  Are you sure? yes | no

Janet wrote 10/28/2020 at 08:13 point

Hi  there - could you please clarify the materials list. It looks like we need brass wire, but is brass rod also needed? Thanks!

  Are you sure? yes | no
