5th Annual Putt Putnam County

Castlemakers 2021 Putt Putnam County viewed down Franklin Street.
Mini-golf holes were down both sides of Franklin Street during our annual Putt Putnam County event.

The Covid pandemic seemed to unleash a little extra creativity in our community and it showed in our annual Putt Putnam County tournament. We certainly had the largest turnout yet with 14 locally built mini-golf holes at the event held again during Main Street Greencastle’s October First Friday downtown.

There were so many interesting holes this year it’s too hard to pick out my favorites. Ranging from the fairly simple “Back and Forth” (why didn’t I think of that?) to our first Halloween themed and a pachinko inspired hole called Plunko. And really, making a piano sounding board with strings into a hole so the golf ball made sounds?

There were even a few apparently stored re-worked older favorites that apparently, including the Kirsch Dental ‘hit the ball through the chomping teeth’ and PCPL’s Alice in Wonderland (don’t go down the rabbit hole though!). There was really too many holes to detail and I can’t do them all justice. If you didn’t make this year’s even be sure to come next year to play through the course. Or better yet, start planning to build a hole and bring it to the 2022 event – Friday night October 7th in front of Castlemakers on Franklin Street!

It’s the time of year to start building a mini-golf hole for Putt Putnam County! This year the mini-golf holes will be on display and playable during the October First Friday from 6-8 pm.

For the annual event youth, families, groups, and businesses create a mini-golf hole to bring that evening as part of the mini-golf course on Franklin Street. There are more details on the event, including building guidelines, on our website project page. We’re also certainly glad to help you build one. We’ve made some of the simpler holes in less than 2 hours, so don’t ‘putt’ off building one!

Holiday Making

This year we decided to pitch in and help Main Street Greencastle’s Santa in the Park project by making holiday ornaments to give away in Santa’s gift bags. We’ve held classes in making holiday ornaments before, so it seemed like a natural fit with one big difference. Instead of making 5-10 ornaments designed by class attendees, we needed to make 500 ornaments for the gift bags in 2 weeks or less!

3D printing the ornaments, which we’ve done in our classes, was out due to the time constraint. Recently I helped a local entrepreneur make his parts for a new product idea on our laser, creating a little over 150 pieces in 15 minutes. They needed to be extremely precise and were slightly smaller than ornaments, but that had me thinking this was the way to go. What we needed was a simple to engrave & cut design that could be done in a reasonable length of time.

A local high school student, Hyrum Hale, came up with design that with a few modifications we could use. Our first prototype in green acrylic looked nice but wasn’t really visible on a tree, plus enough acrylic was hard to find due to Covid. Getting it to engrave/cut quickly required additional work; size of the ornament, material choice & availability, laser settings, and laser bed calibration/set up all were factors that determined time per ornament, quality, and repeatability. Making 500 items of anything means you learn a lot!

Although the cutting/engraving time was still substantial, we made the deadline and are really excited for our first time doing this. There’s a few extras at the Makerspace if you’d like one. We’re also already thinking about a new design for next year…

Covid face Shields

Thanks to a gift from SeeMeCNC in Ligonier Indiana, we’ve been able to donate an extra 150 face shields to Putnam County Hospital in case they’re needed for a Covid-19 case surge.

Last month we started making face shields for those that needed them, but 3D printing can be a slow process. You can do some things to speed up/optimize print time, but if you need a lot of something it’s often not the way to go.

Steve Wygant at SeeMeCNC/Blackpoint Engineering, who makes 3D printers and designs plastic injection molds (among other things) recognized that problem and did something. Within hours he took an open source face shield headband design used in Europe and turned it into an injection molded piece. Then they took their in-house machines used for 3D printers to make headbands and face shields for others. They even started gave away cases of the injection molded parts to groups like Castlemakers who were making and donating face shields in their local community.

We took their headbands and then created face shields by cutting overhead transparencies and report covers to make the shield. Thin clear plastic is in short supply everywhere! Our lasercutter works well to cut overhead transparencies quickly, but the slightly thicker clear report covers us a material (PVC) that’s not safe to lasercut. For those we developed a template we could use with our Cricut Maker. I’ll add some details on our covid-maker webpage.


Makers & Covid

Our blog posts have been running behind lately, but we’ve been busy the last few months. We’ll update with some older entries since like many folks we’ve had more ‘stay at home’ time with the COVID-19 mess that’s been going on.

Even though we’ve stopped having public events since mid-March, there have been things going on inside (using recommended guidelines). Our main 3D delta printer has never been worked so hard in such a short time since we got it 3 years ago.

The picture to the right has some examples of what’s been made there to help first responders and others with the COVID-19 battle. We can’t make things in large quantities, but we can fabricate and adjust quickly – plus worldwide the makerspace community has rapidly stepped up to help people where they can. Longer term existing manufacturers will and are already starting to fill the gap, but it sometimes helps to do locally what can be done until the gap is eliminated. We’ve got a special webpage with some local covid making projects in Putnam County and more details about how the face shields, face masks, and ear savers can be made.

Girl Scouts / Makevention

This last Saturday we had 2 events going on in 2 different cities, a bit of a landmark for Castlemakers. In Greencastle we had our first STEAM class for the Girl Scouts of Central Indiana. 15 girl scouts and parents from Indianapolis learned about sensors and coding using Circuit Playground Arduino based boards.

At the same time, in Bloomington, we had a booth at Makevention, our 2nd year there.  Makevention is a little harder to describe. If you’ve ever been to a Maker Faire that’s close, especially this year since they added workshops and presentations. Makevention is a celebration of the Maker Movement, you can learn about all kinds of DIY/making – from robotics to soap to swords/knifes to lock picking to…

At our booth we had some of the PuttCode robots which we used on the CoderDojo mini-golf hole, although several other holes from previous Putt Putnam County events were there also. The other booths were also interesting, it’s a great event for seeing what other groups in the area are doing and making. It’s usually the last Saturday in August and definitely worth attending.

 

Making Kinetic Art

If you’d like first hand experience in building a kinetic art piece, Volunteers are needed through 3/31 with a new sculpture created by Phillip Beesley and the Living Architecture Systems Group in Bloomington. “Amatria” is a sentient architecture installation on the 4th floor of  Luddy Hall just off 10th street that will be visible within the campus.

The new sculpture  is composed of polymer & metal scaffolding structures that hold glass vessels (including vinegar batteries) that power the LED lighting & kinetic mechanisms responding to motion & sound.  Most makers will recognize many of the components, from Adafruit circuit boards to laser cut acrylic components being made on location. The delicate mechanical moving structures alone are amazing, but with the network wiring/sensors/circuitry and software add another whole level of complexity. It’s not running yet, but will be by the new building’s grand opening April 9-13.

Check it out sometime or better yet volunteer by 3/31 for great hands-on experience with an extremely complex Internet Of Things (IOT) sculpture. A flyer is posted on our Makerspace window with more details or you can simply visit the 4th floor of Luddy Hall in Bloomington between 10am & 7pm through 3/31 to volunteer. We’re also offering an IOT class on 4/26 at the Makerspace, although for beginners, not anywhere near this level!

2nd Annual Putt Putnam County Recap

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.

Putt Putnam County Playoff

Scorecards & voting ballots were available for those playing the course.

Last month was our first annual Putt Putnam County miniature golf course set up at the Putnam County Public Library. A first time event with pretty limited promotion we were unsure about attendance. Turns out it was great, there was a steady crowd in the Kiwanis Room downstairs in PCPL – two estimates put it at 70-75 people for the two hours we were ‘open’. The designs were fantastic and most played the course multiple times.

A little refresher on our fall build project. Teams were formed in August and September (most were 3-4 kids working with a mentor) to design and build a miniature golf hole with Castlemakers supplying any materials if needed. There were 5 categories for judging and if youth were involved they were encouraged to do most of the building. You can read more about the build guidelines & categories on our project page.

This hole won best Putnam County themed hole, even though the moving covered bridge didn't get completed.

We’ve already used holes in another event and were asked to bring them to another in February. So one learned lesson is making a few more portable holes. And the large jello moat seemed like a really great idea at the time but…

I also overhead some mentors talking about the advantages of building the holes in a common place (our makerspace) where the groups could see other group’s progress. We’re definitely doing the event again in 2017, for there’s already scheming minds planning more elaborate designs.

Castlemakers Model Rocket Launch

Despite the forecast, it was a beautiful sunny afternoon at Big Walnut Sports Park after we delayed the rocket launch a week. Besides the DooDad rockets built by the Castlemaker Kids, we had others show up with their own rockets, creating quite a show. We ended up with multiple launch pads and variety of different sized rockets and objects becoming airborne.

The ‘objects’ part are a little hard to describe, although they all used rocket engines. There were various polyhedrons and cardstock printed lawn darts (no chute, but colored with crayons by some younger kids – landed with a ‘thud’ nose first). Then there were the flying plates…

All of the kids (and a few of the adults) learned the proper setup and launch procedures before launching the model rockets. Thanks to the Greencastle Parks & Recreation Board (along with the Putnam County Airport) for letting us use Big Walnut Sports Park for launching the rockets. And a special thanks to Nick Adams for teaching the class, bringing his launch equipment, and teaching/supervising everyone  who launched that day. And to Jonathan Green for bringing his tub full of objects, it definitely added some more fun to the event!
