The Castlemaker’s Shovercraft showing/demo
will be this Saturday (8/30) at the Greencastle Farmer’s Market on the square in Downtown Greencastle. These leaf blower powered hovercraft, built by our 9-11 year old Putnam county participants, will be on display a good portion of the morning – so stop by! We’ll fire a few up around 9:30 before the music at the Farmer’s Market starts at 10 am.
These hovercraft are being called them Shovercraft because they only have a hovering fan, not propulsion , so they have have to be shoved. Well and part of the upcoming competition will be landing the craft on a shuffleboard for points. I’m sure we’ll give demos several other times this Saturday, the kids are pretty excited about their craft. Look for us on Franklin street portion of the Market from 9-11 am Saturday.
The project update page can’t keeping up w/ flurry of activity this week, but there are some photos and a video of the work-in-progress so far.
Bloominglabs, a makerspace in Bloomington Indiana, has their Makevention this coming Saturday, August 30th, from 10 am to 4 pm. It’s at the Bloomington, Indiana convention center and you can read more about the event here: http://makevention.org/
Last year they had FIRST & the FIRST Lego League robotics equipment there, it looks like the local high school team at least has a booth this year. Should be a good opportunity to see some interesting maker projects and if you’re interested in robotics get a feel for what’s involved in fielding a FIRST robotics team.
I’m working on Making speaker series this fall to start in October in Putnam County. The first topic will be on the different robotics team competitions – including have our local VEX robotics team speak about what they’re doing.
There’s also an upcoming Robotics Encounter down in Scottsburg Indiana for kids in grades 3-12 on September 27th. It’s sponsored by the local 4H/ Purdue Extension office down there, but out-of-towners are encouraged for the 10 am to 3 pm workshop. You can read more about it in the flyer or call the Floyd County Extension office at 812.948.5470.
Our hovercraft teams have been hard at work & we’ve got a 4th team that will be joining us at the upcoming event. Several teams now have prototype shovercrafts running, there are links off the project page. Our public showing/competition will be at the Greencastle Farmer’s Market in late August.
Quick reminder for the shovercraft teams that we’ll be meeting as a whole group again Wednesday August 13th, 7 pm, at the Southside Community Center (605 Crown Street).
Usually we think about kids making things, but the other day I realized that un-making things can be every bit as important. Maybe it’s how we begin tinkering & building things, learning how existing things work by taking them apart.
It started with my daughter and her friend asked to watch a movie. I suggested they go out in the garage instead to tear apart some equipment that I’d gotten for our maker group to build things with. The old equipment was made mostly of 80/20 extruded aluminum (some call it erector set material for adults) and it was held together with lots of things that needed to be unscrewed and disassembled.
I was a bit uneasy thinking that it wouldn’t go over well. I wasn’t sure they would like it. But turns out I was wrong… they loved it!! 45 minutes later there was nothing but a pile of pieces laying on the garage floor!
In the process, I learned something from watching/helping the kids take it apart. I really never thought about how to use a screwdriver, you just sort of well… do it. But then in watching it hit me at some point I must have learned from someone else.
Little things like knowing how the blade or hex wrench should go into the screw head, keeping the screwdriver straight up so it doesn’t slip out and get the best torque – even using the long side for leverage with an allen wrench to break the screw loose are things that is best experienced. With some occasional guidance and encouragement you also don’t give up on the task and keep learning. Kinesthetic, hands on learning isn’t the same as reading it in a book or watching a video. And the girls started encouraging each other and before long I was hearing “I get to do that one…” – and they were having fun while doing it!!
So get out and help some kids take things apart. Building things is good fun too – don’t miss the opportunity to help them learn the tactile and hands-on portion of learning to use tools and components whether it’s making or ‘un-making’ things. Goodness knows there’s not as much in schools anymore.
In fact, we’re going to host a tear down session of more equipment for the Castlemakers group this Saturday @ 11 am. We got lucky enough to get more old equipment to tear apart. Join us if you’d like – I can’t promise how long after that it will stay assembled, but we’re going to have fun tearing it all apart!!
I’ve been negligent by not talking about some other maker events going on here in Greencastle. Putnam County Library has been having Maker Tuesdays – short 1-2 hour events at the Public Library. I’ve only seen a flyer on it posted at the library but I was able to find something on the Putnam County Library online calendar. There’s another event coming up Tuesday July 29th, or stop by and I’m sure they can give you more information.
We had our 2nd Castlemakers meeting upstairs in the Eli’s Books community room last week; it was the official shovercraft kickoff meeting. It started with a video of a simple home built ‘shovercraft’ someone built and then the kids discussed what might be needed to build one.
Then there was a small demo of a simple hovercraft made with a balloon, disposable water bottle, and an old audio CD (with lots of tape on it). The demo was a hit with the kids judging by the number of balloons used!!
The kids involved got to find out their team members (3 teams with now 4 kids each) and their adult mentor for the project who also helps them on the project. There are lots of possible designs and one of the first thing they’ll be deciding includes: what shape (circle? rectangle? boat shaped?), what type of ‘engine’ (or leaf blower), and chair/no chair. Plus lots of other items, including how to decorate it! Each person there got a notebook to draw and keep notes in – the young designers/makers took off from there.
Our next full group meeting will be on July 10th at 7pm to review how the designs are coming, although the individual teams will be meeting between now and then. We now have a goal for completed shovercraft and either a ‘who goes the furthest’ or hovercraft shuffleboard competition on August 16th or August 23rd – depending on our final location. There will be more information and updates later!!
The mentors have met after our last group meeting and we decided on a Shovercraft as our first group build project. It looks like there will be at least 3 groups of 3-4 kids building one, then we’ll have a competition/race in August.
Our next meeting is Thursday June 12 at 7pm in the Community Room above Eli’s Books just off the square downtown. Please feel free to join us, we have 4 mentors willing to give their time so we can investigate, design, and create these craft for the competition. Even if you haven’t been involved so far, you’re welcome to show up and have your 9-14 year old daughter/son participate in this youth-centered maker club event.
Keep watching our Projects page for more details on how the team builds are going & when we’ll have the challenge/competition for the groups in August.
Many makers have or use a 3D printer. I’m sure there are some here in Putnam County already, but I’d like to see a publicly available one. I’m personally building a 3D SLA printer with some help from some other folks, but would love to connect with other folks near Greencastle that have a 3D printer. Respond to this post or send me an email if you have one. There’s a certain amount of learning in making these work & we can build our skills/knowledge together.
Last week I was able to visit 3D Parts Manufacturing in Indianapolis to see their operation. Neat operation and Kim Brand is doing some real interesting things around 3D printing. If you just look at their website you’d get the impression that they’re mainly involved with the high end 3D printers, and they certainly have those, but they’re also working on creating a program for middle school kids that includes a 3D printer, support, and the lessons to go with it. An IBJ reporter was there the morning I visited and an article on what they’re doing just came out in this week’s Indianapolis Business Journal. I’m hoping to get Kim over here to Greencastle later this year.
There are several different types of 3D printers, explaining some of the nomenclature can help you understand those types.
3D printing is an additive process vs. the traditional subtractive machining used with CNC, lathes, and many other traditional fabrication tools. One of the real breakthroughs in more affordable printers was the open source printers that first started appearing in 2005. Many of these were based on the RepRap design goal to create a machine that could print most of its parts. The RepRap based designs, and most current printers less than $1000, use Fused Filament Fabrication (FFF) which extrudes a thermoplastic. But other options are starting to appear including some lower cost Stereolithography (SLA) designs. SLA has traditionally been one of the more expensive 3D printing methods because of the material cost and laser control. I’ll write something on low cost 3D printing methods and the equipment we’re looking at for Castlemakers in a future note.
Thanks to all that made it Monday night at Crown Equipment to the meeting on creating a Putnam County maker group for youth. Seemed like a fairly good turnout for a first time meeting. We had 21 people there by my count – enough to get something going!
We briefly covered what the maker movement is, categories of possible projects, the making process, and some ideas for projects groups could do. There were also some Arduino boards & shields, a small hand built catapult, various magazines full of possible projects, a 3D printed chess set, and lots of pictures of maker groups and built projects. Several people indicated they wanted to come, had conflicts, and to count them in – I’ll get you the info presented. If you’re reading this and interested, drop me an email and I can also send you a copy of the presentation.
We also gave out some forms to the kids with a listing of possible project categories and a form for possible mentors to list their knowledge/expertise areas. I’ve now got a stack that is apparently bigger than the attendance – some families only were able to send one parent and several people there were representing other families too. It’s going to take me a few days to get through these and compile the list. If you were there at the meeting please be patient until I can read through & summarize the results. If you weren’t there, here’s a copy of the youth interest form and the mentor form. You’ll have to print these out and email them back – or heck maybe in true maker fashion maybe someone can make an online form!!
Mark your calendar for Monday, May 19th to learn more about Castlemakers and what we hope to do in Putnam County. Crown Equipment has been generous enough to let use the Tiger conference room at the plant for us to discuss a maker group for kids 9-14 years old and their parents. And you’re invited!
I’ve described what is a makerspace is in a previous post, but you certainly don’t need one to make something. We need to unleash some of the creativity, innovation, and passion here – especially in our youth. So let’s meet to create a larger group that actually makes things!!
What: Public meeting on Castlemakers for youth-oriented makers and their families. Where: Crown Equipment, Tiger Conference Room @ 7pm on Monday, May 19th. Who: Parents and kids wanting to create & build things, along with anyone wanting to help create a local makerspace/fab lab.
At the meeting we’ll briefly go over the Maker movement, describe what we’re doing here in Greencastle, share some ideas of possible projects, and then ask folks to let us know their interests. I’m interested in 3D printers & laser cutters for example, there are others interested in robotics, drones, and hydroponics… well the list could go on and on. The goal is being a community-based group, the get-together is about sharing interests to determine where we can pool resources and share ideas and skills. An open-source model of building and creating things.
Can’t make it to the meeting? Sign up for our email list by sending a note to email@example.com. We’ll send you updates and put you on our list.
Not sure if you want to participate yet or maybe just curious what’s it’s about? Maybe even not sure that you can contribute? That’s fine – just come – Listen, Learn, and leave. Although, our real hope is that you’ll become so excited that you’ll participate. Because that’s what it is really about, creating something with others for enjoyment – and maybe learning a new skill or sharing an old one with other people.
Next weekend (5/16-18) in Dayton Ohio will be the annual Dayton Hamvention. With about 25,000 people attending that are interested in building ‘stuff’ and over 2000 outside flea market spaces (never mind all the indoor commercial vendors there) it is truly an amazing event for makers. This year’s theme even reflects that – “Makers… the future of Ham Radio.”
Many people when they hear about Amateur Radio (or Ham Radio) Operator imagine an elderly guy with a green visor hunched over a telegraph key. Matter of fact several years ago Jay Leno pitted teenagers using a cellphone against some amateur radio operators using morse code to see who was fastest at sending a message (the ham radio operators won).
Amateur radio these days is far from that doing everything from building and launching satellites, providing emergency communications during catastrophic and public events, bouncing signals off the moon to talk with other ham radio operators and much, much more. Many of our astronauts are ham operators and use the amateur radio station in the International Space Station to talk to classrooms. There was a group when I was in Terre Haute that was trying to put together a classroom broadcast to the space station -I’ve often thought that it would be a good educational experience for kids in Putnam county to talk live to an astronaut in space.
If you’re interested in finding out more about amateur radio in Putnam County, George Edenfield (KB9RZK) would be a good person to contact. He’s the IT person at Putnam County Public Library & you can reach him at 765.653.5327. I’m not longer ‘radio-active’ but still have my license and use the skills in electronics/home-brew projects/fabricating things that I learned as an amateur radio operator. Or head over to Dayton next weekend and gawk to learn more. If you’ve never been you’ll definitely be impressed. – Chris (N9VFD)
