What happens at Castlemakers

We often get questions about when to visit Castlemakers; the best place to start is our events webpage. You can drop in during Open Shop or also attend one of the events listed.

4th Graders from North Putnam learn coding on a micro:bit
Putnam County Kids Count catapult design testing with fruit, candy and marshmallows.
Kids test their designs with different size & weight projectiles.

For people not familiar with makerspaces, they may not realize everything going on. For example, limited ‘retail’ hours (what we and other makerspaces often call Open Shop time) reflect the volunteer nature of them. There are lots of passionate people and activities going on outside those times, often working individually and with other organizations.

Two teams combined efforts to build a 10 cell tetrahedral kite.

For example, in the last 2 months Castlemakers worked on a number of youth-oriented events not listed on the webpage or on social media. Just a few weeks ago we were out at Heritage Lake working with over 50 kids at Putnam County Kids Count helping younger kids build and test catapults, then the older ones build and fly tetrahedral kites!

Another outreach event involved 2 other organizations in early May: Castle Arts and Putnam County 4H. Thirty North Putnam School Corporation 4th graders came to downtown Greencastle to learn about computer coding. While one group learned and used a robot at the 4H office to sort and count chips, the other group was at the Makerspace.

This robot was coded to put each color chip in a different bin.

Christian Destremps did a fabulous job teaching them algorithms/coding around the corner at the 4H office using Lego EV3 kits built into a color chip sorting robot. Castlemakers helped with assembling his robot design and 3D printing bins to catch the different colored chips.

Learning how G-code is used in 3D printing.

At the Makerspace we showed them how coding is used in 3D printing, laser cutter/engraving, and CNC machines. One section saw the coding (G-code) in action with our makerspace fabrication tools. At the same time the other section programmed a micro:bit, a small micro-computer board, using a block-based coding editor.

It really demonstrates what can happen in our community when different organizations pool their resources together. You’ll be hearing a lot more about the micro:bit board in the next few months here in Putnam County.

Greencastle First Friday Events

With this month's Laua theme we had a palm tree & create-your-own Tiki head out front.
First Friday project to color/create a Tiki head out in front of Castlemakers.

Our downtown location gives us a great opportunity each month to participate in Main Street Greencastle’s First Friday. Each month we not only have ‘open shop’ to share what’s going on inside the Makerspace, but also try to have some themed making events that folks can see / participate in.

This month Main Street was promoting a luau theme – so making a carpet tube palm tree and some Tiki heads were naturals. The Moai head printed on our Rostock Max 3D printer inside was so big that it took nearly 11 hours to finish; although started at noon I’m fairly sure no one else saw the finished print Friday night.

Then there was the ukulele playing Lego Mindstorm robot that Jacob built for the event. Thanks to Putnam County 4H we’ve had some EV3 robotic kits on loan for a while, using them in our CoderDojo, projects like our PuttCode, and getting kids & adults interested in robotics.

Thanks to Jacob & the rest of the Hale family for helping out – not only the things they made but with running this great family oriented monthly event.
