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.

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.

Photogrammetry and 3D Printing

Castlemakers offered our first class on photogrammetry, or using photographs to create 3D objects, in October. But the more interesting story to me was how we got there. It began just before our Intro to 3D Printing class last spring, when a couple of folks wanted to learn about 3D printing so they could hopefully print things from an archeological dig in Italy in the summer. While I had experimented some with earlier software, this was mostly new territory.

But Rebecca, one of the students in the class, took it to another level. She was able to get a copy of a professional program, Agisoft, then take pictures at a Roman dig site in Italy this last summer. Using the program, she generated 3D images of artifacts they found and even took photos of the excavation at the site (a Roman bath house) which she was able to turn into a 3D image. When she got back in August, in a little over a week she was able to 3D print not only artifacts but also make a model of the dig site using the 3D printers at Castlemakers.

As we prepared for the Castlemakers class to show others how to do it, we discovered what may be an even better solution – a program called 3D Zephyr. We decided to cover both, especially since 3D Zephyr has a way of extracting photos from video to make the 3D image – a pretty amazing feature! The experiments will continue with local landmarks and we’ll be doing the class again this spring.

Putt Putnam County Wrapup

Putt-Putnam-FranklinOur 3rd Annual Putt Putnam County, held on Main Street Greencastle’s October First Friday, became our largest yet. This year anyone in the area was encouraged to create/build a mini-golf hole for everyone to play. The end result: we ended up with a course that ran from Indiana Street down Franklin to Vine Street!

The community built mini-golf holes really added to the diversity, from the Kirsch Dental chomping teeth to South Putnam School Corporation’s football hole. It also included an impressive arduino-powered hole from Tenzer Center and Wasser Brewing’s final hole led up to their outdoor serving area & music.

Putt-Putnam-NightAnd of course the Castlemakers built holes were impressive as always with a Skee golf-ball hole,  mini-golf bowling alley, Horcrux hole, and a Candyland hole that had a chocolate river (maybe using chocolate pudding was a bad idea). But will cover those and the other mini-golf holes in a later post.

Special thanks to all the organizations that brought mini-golf holes and Main Street Greencastle for helping with the city to block off Franklin Street for us. It’s not too early to start thinking about an entry for the 4th Annual Putt Putnam County in October 2019!

Our 3rd Annual Putt Putnam County mini-golf hole building tournament is underway and the holes this year looking better than ever. With about a dozen mini-golf holes that I’m aware of, there’s still time to put together a quick hole for a night of family fun.

This year we’re holding the ‘putt off’ at the First Friday event in downtown Greencastle from 6-8 pm. Main Street Greencastle is helping us to arrange Franklin Street to be blocked off, so we’ll have the holes down the street as part of the First Friday event. And several community organizations are also building holes for the event.

With entry holes from “Alice in Wonderland” to “Virtual Golf” it promises to be a fun, no charge event for the community. Come join us on October 5th!

2017 in Review

So much happened at Castlemakers in 2017 it’s been a challenge to keep the blog current. This entry started in December, but had to be finished in 2018 – which I guess highlights 2017’s theme of expansion and growth!   2017 growth included:

Castlemakers CNC addtion, a Nomad 883.
Castlemakers CNC addition, a Nomad 883, making a wrench out of a  piece of aluminum.

    • Thanks to several generous gifts, Castlemakers added more equipment in 2017. Perhaps the most notable was our desktop CNC (Computer Numerical Control machine, a Nomad 883) which we’ve now put into use and will be offering the first class in January. Techpoint Foundation for Youth also gave us 10 Chromebooks, which are getting heavy use in our Castlemakers CoderDojo (a youth coding club) and the gift helped with our classes.
    • Since last June we’ve had general public STEAM oriented classes essentially every month for the old and young. From 3D printing & Arduinos to lasercuttering, they provide practical learning using technology where the participants take home something they make. What a great way to learn!

Castlemakers CoderDojo met the first Saturday afternoon of every month in 2017.

  • With a new Makerspace soft opening in December 2016, memberships now offer 24/7 access to the physical space and equipment. ‘Open shop’ times offer anyone a chance to use/try the equipment for their own projects. But the real value is the associated people/members and their knowledge. Plus it’s a great way to try/use an expensive piece of equipment that you can’t justify for yourself.

But the real growth is with the makerspace community & people. It’s the December CoderDojo with 10 kids spending their Saturday afternoon practicing computer coding along with showing and sharing what they were working on. You could see kids programming a tablet to adults there teaching robot navigation and a 12 year old coding a humanoid walking in an online landscape he designed.

It’s also listening to a member take what he learned in our laser class to create a wooden 3D map of his farm. It’s a 3DPO regular showing off the 3D printer he designed or seeing the cable supported 3D printer in which the print size is only limited by the room’s walls.
2018 looks very promising indeed…

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!

2nd Annual Putt Putnam County Recap

Course setup, we even had a few homemade putters in the bucket by the door.

Earlier this month we had our 2nd annual ‘build a mini-golf hole’ competition, which was held at new location at the Makerspace downtown. Well, sort of… too many holes to have it inside, so we lined them up on Franklin Street sidewalk in front of the Makerspace the first Friday of November. And what perfect weather it was for playing a round!

Always love to see creative mini-golf holes and this year’s build was no exception. The guidelines are on our Putt Putnam County webpage, but the basic idea is simple: get together a group of folks and build a hole. We provide materials, create/add you to a team & mentors if you need it, plus a time/place to play when done. And of course those cute little pencils and a scorecard.

This year there were a few more family built holes, but it was a mix of different team entries. Of the eight holes there, a personal  favorite was Antigravity – you can view a video here of this creative hole in action. This year there were a lot more moving part entries, a category we added this year. Under the Sea’s motion was impressive (and it’s assembly/disassembly capability) and the steam punk look of Time Turner’s entry turned out even better than the builder’s thought.

Time Turner, a steam-punk hole built by 11-12 year old kids, used a BBQ rotisserie motor and old bicycle inner tube to rotate the clock face (which has a paddle underneath). The pulley and golf ball tee were 3D printed & the clock numbers were cut using the Makerspace laser cutter.

Our goal next year is having an earlier completion date at a First Friday event downtown and more community organization built holes. Start coming up with your ideas now; you don’t need to be involved in Castlemakers to participate & have fun!

Thanks to all the participants that built holes, mentors that coached the younger teams, and everyone that came out Friday evening to enjoy the fun. And to Headley Hardware for donating some of the project materials.

October Update

Join us this Friday, 11/3, from 5:30-7:30 pm for our 2nd Annual Putt Putnam County competition. We’ll have the mini-golf holes outside the Makerspace on the Franklin Street sidewalks. Try your skill at these home-built miniature golf holes and vote on your favorites. Pre-competition intelligence is indicating there is a lot more motion designed into this year’s holes…

And of course our monthly CoderDojo is Saturday 11/4 from 1-4 pm at the Makerspace where youth are always invited to learn more about computer coding from professional programs and other kids!

It’s Not Rocket Science

If you walked by the Makerspace this summer and looked in the window, you may have noticed a very large model rocket. It was the first stage of a creation that Nick Adams, who taught our ‘build a model rocket’ class, built last year and launched. Several people have stuck their head in since it left and asked us where the rocket went. The short answer is he prepping it for an even higher/faster launch this Labor Day weekend in Kansas.

Earlier this year Nick asked if we could make something that would plug the air intake holes, the kind of project we love! When you go supersonic a flat surfaces creates even more turbulence, so for his upcoming flight he wanted a more streamlined version. Plugging 4 intake holes on the side of the rocket would help.

Different versions of the intake plugs.

We initially fabricated a plug out of foam, using a hot wire cutter at the Makerspace, then scanned the piece so it could be 3D printed. Creating the styrofoam piece was easy, scanning… well the Makerbot Replicator we have wasn’t quite up to the task initially. Learned that covering the foam with masking tape helps (the foam color and irregular surface created problems), but it was still less than a satisfactory design.

Then one of our younger makers, Ephraim, helped by creating by creating a quick model in Autodesk’s Inventor. That design came closer, but we missed measuring a few key dimensions like the chamfer where the plug goes into the rocket. We finally ended up redrawing with Fusion 360, which turned out to be the best solution. Although the program has a steep learning curve, it allowed us to make several more design changes quickly & easily to get the 4 pieces printed out last month.

This weekend Nick’s letting Castlemakers take the rocket to show off at Makevention in Bloomington, Indiana – an annual celebration of making things. Located at the Monroe County Convention Center, it’s open to the public and a great event! Stop by and see the assembled 12.5 foot tall rocket and also stay tuned to Nick’s YouTube channel. I’m sure he’ll have a video of the launch posted not long after the launch on August 30th!
