Laser Engraving/ Cutting Class
Attendees watch as Rodney cues up their design in the Laser Engraving/ Cutting Class.

Since last summer Castlemakers has been teaching more STEM/STEAM/Making classes for anyone interested in our community. If attendance and topics can be a judge, then our effort has been a success! Our March Introduction to Laser Cutting class, which we wanted to limit to 8 people, had 10 people (squeezed a few more in at the last minute) including folks that drove from Kokomo & Whiteland, IN to attend.

In April, we took on a very challenging current topic – Internet of Things (IoT). The IoT class allowed people to not only learn about IoT & but also build an IoT device that they could take home. We’ve already had additional requests to learn about it and will repeat the class again in the future.

Group discussion of how the IoT device gets data to a webpage that students were accessing.

In May (5/24) we’re starting a new class series called Design to Product. We’ll begin by teaching folks how to use 3D software (like Fusion 360) to design a product, then in subsequent months you’ll learn how to make them using a 3D printer, laser cutter, or even a desktop CNC machine.

Learning with Hams…

Students learn about Amateur Radio Technician license privileges.

Last night PCAUXCOM, the local Amateur Radio emergency communications group, began a FCC Amateur Radio operator’s license class at Castlemakers. It’s a great way to study for the test – although you can self-learn the material to get a license.

What they’re doing however embodies what often happens with vocations and hobbies – people practicing and learning with other people. Not only to learn quicker, but for enjoyment too. It can help make challenging things easier; in some cases even provide focus and accountability. In today’s noisy world with more opportunities than time that’s often difficult.

Makerspaces, and one of Castlemakers’ goals in particular, can bring communities of people together to share knowledge and skills by providing a space, events, equipment, and even just a reason for people to share something. Whether it be a CoderDojo (bringing kids and programmers together to explore programing languages), folks interested in 3D Printing (which also met last night to see printers in use at a high school classroom), or Amateur Radio operators and emergency volunteers assisting others to get a communications equipment operating license.

The PCAUXCOM group is meeting every Monday evenings from 6:30 to 8 pm at Castlemakers, it’s free and open to all, and still not too late to join in. They will also be offering a licensing test locally here in Greencastle just after the course is finished, contact George Edenfield for more information.

Electronic Cutter Class

In the December class we learned how to design and create a greeting card with an electronic cutter.

Our December class was something new for many of us, learning about electronic/vinyl cutters. There are several different brands available; we were given a desktop Cricut and there’s some local expertise so that’s what we used! But the basics apply to all of them. The Cricut Explore we have in the Makerspace will cuts and draw using different color pens on a variety of different thickness material including paper, foil, vinyl, cardboard, fabric iron-on, magnets, and even emboss leather.

Laurie Hardwick, who has several Cricut machines, taught the class & did a fabulous job. After showing some great examples, she then covered the design software. With a 2 hour time limit folks chose to modify existing designs, but it is possible to import images into the software (and perhaps a later class). It was amazing how such a professional looking product could be made in such a short time!

Several folks wanted to come back and try more. Our machine is available for anyone to use during open shop times or even by special arrangements. Castlemakers also offered to host a meetup for Cricut or Silhouette users, just get in touch with one of us. Last year we had one girl come in and create letters for her 4H project, it certainly makes it easier that using stencils or cutting out your own!

Castlemakers July Class

One of our main goals as a non-profit is providing educational opportunities to the community. Like our Learning to Solder class in May and our upcoming Introduction to 3D Printing Design July 8th (2-4 pm at the makerspace).

In May participants built an LED Chaser (or Larson Scanner), to get first hand experience soldering electronic components, LEDs, and an integrated circuit on a circuit board. Thanks to George Edenfield of Putnam County Auxiliary Communications (local Amateur Radio group) for leading the class.

For the Intro to 3D Printing Design class, we did a prototype class last December when we had kids design & print holiday ornaments. Everyone had fun and we learned that too many people trying to print 3D parts at once can take a long time! We’ve added 2 more 3D printers in the makerspace, more laptops, and changed to a quickly printing basic design that offers more learning.

Demo ring for our upcoming class, other orientations will be used also!
Demo ring for our class,  but decoration can be reoriented…

In the upcoming class (for both old and young) you’ll be designing a custom ring to fit your finger and adding an adornment on top. It’s a great way to learn the basics in Tinkercad and prints in 4-5 minutes per ring depending how elaborate you get. Special thanks to the Maker Lab at Chicago Public Library for the idea – like almost all makerspaces they willingly exchange information and share ideas to help the maker movement!
