dodecahedron-connectors

I honestly can’t remember where I got the idea to make a bunch of dodecahedrons for Maker Faire Milwaukee came from, but I do remember looking at Thingiverse for some connectors I could use with 1/4″ dowel rods. I know I tried Trammell Hudson’s design, since I always admire his work, but I was not using pencils, so it didn’t work. I did attempt to alter his file, but ultimately ended up designing my own file, which worked well enough that I wanted to share it. (Check out Dodecahedron Connectors on YouMagine.)

So I made nine dodecahedrons that could hang from the ceiling in the Dark Room. And since they’d be in the Dark Room I figured I should use fluorescent filament to create the connectors, and fluorescent paint to paint the wooden dowel rods, and with help from Kathy H. at Milwaukee Makerspace, we got everything painted. Sadly, we did not get the blacklights set up in the Dark Room due to budget constraints, and there was too much light where they were placed, and we had to bundle them all together, and… well, anyway, they turned out great, despite a few issues with presentation.

dodecahedrons-small-01

I’ve also made a smaller (hand-held) model for home. It’s small enough to fit on a 13″ MacBook Pro, though I might hang this one from the ceiling as well. Or maybe make it into a lampshade. I don’t know yet.

dodecahedrons-mms-01

This is the original version, which uses 12″ long, 1/4″ diameter wooden dowel rods. A pack of 100 dowel rods is under $15, and a roll of fluorescent filament is about $22. Since you need 30 dowel rods and 20 connectors per dodecahedron you can easily build three large ones (or a lot of small ones) for under $40 USD as long as you’ve got access to a 3D printer.

Did I mention I really like dodecahedrons?

audio-face-5404

One of the projects I built for Maker Faire Milwaukee this year was AUDIO FACE [APC-320], which consists of the following things.

  • A cabinet built from scrap wood and plastic found at Milwaukee Makerspace and Brinn Labs
  • An Atari Punk Console that Kathy C. from Milwaukee Makerspace gave me for my birthday (which was already assembled!)
  • A 320 watt car stereo amplifier that someone donated to Milwaukee Makerspace, that I then gave to Jon H. for Disco Dalek, and he then gave back to me a year later
  • A really nice car stereo speaker I got from Andy A. from Milwaukee Makerspace for about $10
  • Some LED lights from Les, a long-time Maker Faire Milwaukee volunteer
  • A hefty 12 volt power supply and a 12v to 9v buck converter, which I purchased from Amazon for about $25
  • Some random arcade button I had lying around, a handful of drywall screws, and probably a few more miscellaneous things I forgot…

The concept behind this “noisemaker” is a continuation of what Maks, Dustin, and I did back in 2017, which was a series of devices that made sound when action was taken. Typically this was pressing a button, and often with potentiometers of some kind to alter the sound. I ended up building a lot of Arduino-based sound devices. Are these synths? Maybe… Are they noisemakers? I guess so.

When you press the button you are responsible for the creation of the sound. If creating weird noises embarrasses you, you have to deal with that. If you are getting into it and everyone else hates it, it’s on you. Only momentary switches are used so no one can turn them all on and walk away. If you’re there, you’re the cause of the sound.

Many of the devices from 2017 were somewhat fragile, built from small pieces of scrap material, and they sat on a table. For AUDIO FACE [APC-320] I wanted a large cabinet, which was pretty much a requirement due to the large speaker, amp, and power supply. While all of the 2017 devices were extremely cheap (built from scrap, found and scavenged speakers and components, and $3 Arduino boards or ATtiny chips) AUDIO FACE [APC-320] was a bit more expensive, probably costing close to $40 USD.

audio-face-5407

As a sculptural piece, I think AUDIO FACE [APC-320] is interesting because of the contrast. Some of the build material is really nice laminate material or higher quality plywood, but it’s assembled in a slapdash method. There are rough edges that don’t line up, and there’s very roughly drilled holes on each side. While I love precisely designing things, I also love just building with no plans on occasion. Just getting to work and figuring it out as I go. This cabinet is that. At least one person mentioned this at Maker Faire, seeing this as quite a contrast to my other pieces which tend to follow a specific grid or use mathematical concepts. It’s not by accident.

audio-face-5411

One other interesting thing about AUDIO FACE [APC-320] is that it’s sort of a bench. I mean, you can sit on it, and if you dial in the right sound and then sit on the button it makes your insides feel funny. I really like this part and may explore this in the future. I also like the fact that it’s sort of a table or a stool. A weird table or stool with controls in the middle of the top surface that makes noise and vibrates, but still… could be a table or a stool.

mfmke-si-art

While taking a break from reading through all the applications for Maker Faire Milwaukee I had an idea for some art we could use this year. It ended up becoming shirt art after I shared it with the other event producers.

The art consists of an 8×8 grid with 64 items, yes, as always, I try to make these numbers mean something. 8 bit, 64 bit, you get the idea… The color pallet comes from what we used previously for our kaleidoscope design.

The most difficult part was the typeface. I tried many existing fonts but nothing was working. Makey the Robot is (almost) square, so I needed the letters M, K, and E to be square. Stretching existing fonts did not work, so I ended up creating my own type.

mfmke-si-type

Once I had the M, the E was easy. I just rotated it 90 degrees! The K was a bit more difficult, but the line width matches the parts of the M and E, and I then just aimed for the corners to make them end in 45 degree angles so it would all look even. It’s probably the best “MKE” I’ve ever designed.

mfmke-si-shirt

Here’s a terrible photo of the shirt. We still have some left, so if you want one, let me know, and I’ll get you hooked up for a nice price! (The original design was completely square and did not have the long “Maker Faire Milwaukee” logo on the bottom, but Stacie reminded me we should really add that.)

mf-miami-2019-2577

I was fortunate enough to be invited to Maker Faire Miami by Mario the Maker, who I’ve followed online for quite a while, and had met previously at Maker Faire Orlando.

I’ll admit, when he invited me, and told me it was at Miami Dade College (which I had been to before) I assumed it would be indoors. When he told me it was 84 degrees there a few weeks before the Faire, I hoped it would be indoors. I got there and found out it was all outdoors. When people asked me how Miami was, I say “Hot!” (I’m from the Midwest, I don’t handle heat well.)

Besides that darn heat, Maker Faire Miami was pretty awesome. Every Faire in every city has a different flavor, and while I know a little about the Maker community in Miami, it was great to see more of it. Most of my time there was spent assisting where I could, and a lot of that involved helping with the Power Racing Series.

This was the first year for Power Racing in Miami, and the Orlando Crew pretty much took care of everything. We had a few issues with water, and power, and magic smoke, but in the end things worked out pretty good, especially for a first attempt.

Orlando (well, MakerFX Makerspace) also brought along their “Print a Shirt” station, where you can pay $5 to screen print your own t-shirt. (Or $10 if you buy one already printed.) Now that’s how you incentivize making!

mf-miami-hedgeclipper

As usual, Florida favorites included Hedgeclipper and the work from Moonlighter Makerspace. They had a giant tent filled with awesome things.

cnc-drumstick-01

One of the more interesting exhibits I came across was this little CNC lathe made for engraving drumsticks. I was interested in it because it looked like the little CNC machine I built from a kit a few years ago. Indeed, I talked to the Maker and that’s what it was, a heavily modified version of the same kit. We talked a bit about the Grbl firmware and I gave him a few tips on saving the settings. (Check out a video of it in action.)

mf-miami-2019-2632

I met a lot of great people in Miami. I talked with John Edgar Park and I think we bonded a little over our love of documenting and sharing work. I met Abby K. (VEX iCutie) who was super enthusiastic about what she made, and spent time explaining her robot to me. I also got to meet Esteffanie (YouTube, Instagram) who gave an inspiring talk about making and failing, and continuing to try new things.

Overall, Maker Faire Miami was a great event, and I’m really glad I got to be involved with it. If you’re in the Miami area, check it out next year, as I’m sure it will only get better with age!

Want more photos? There’s a bunch in my Maker Faire Miami album.

giant-led-cube-02

This year my “big” project for Maker Faire Milwaukee was a Giant LED Cube. In this post I’ll talk about designing it, and in a follow up post I’ll talk about building it.

I should mention that the idea for this started maybe three years ago. I think it was during a meeting for Maker Faire at Milwaukee Makerspace and I tossed out the idea of building a giant light sculpture using light bulbs. Lance and Chris talked about it a bit and Tom started looking up parts on Alibaba. Nothing came of it that year, and I sort of forgot about it for a while. In fact, I really didn’t think about it again until after we completed the DecaLight last year. Once the two dimensional relay controlled light bulb thing was done I thought going three dimensional would be a good idea.

I modeled the cube in OpenSCAD, and then animated it just for fun. I figured out how many pieces of each PVC joint I would need, and while I originally thought a 20′ cube would be a good idea, after some initial tests (and the unavailability of 10′ PVC pipe) I ended up going with a 10′ cube so the 5′ PVC pipe I could get would work.

I picked up Jordan Bunker’s book PVC and Pipe Engineer: Put Together Cool, Easy, Maker-Friendly Stuff last year and then ended up learning about FORMUFIT which allows you to build furniture using PVC pipe. I had a plan!

giant-led-cube-01

Here’s the first sketch of the Giant LED Cube. By now I had decided that I would use LED light bulbs and standard household lamp sockets. The nice thing about using such common parts is that they are very cheap. I found these Black Bakelite Fixture Socket with Terminals and ordered some so I could test the fit. It was close enough that it would work, and I just needed to make a small adapter. Well, at least 27 small adapters.

giant-led-cube-04

I designed and 3D printed over 30 of these using clear ABS, which is remarkably close to being white, and since you wouldn’t really see them, I was fine with the close match. I cranked these out so I’d be ready when they were needed. Like many parts of this project, they are just press fit into place. The entire thing was designed to be easily assembled and disassembled for making transport and storage an simple affair.

giant-led-cube-03

I had the basic design of the cube figured out, so I decided to work on the controller. Since we’d have 27 LED light bulbs I decided to use an Arduino Mega, which had plenty of I/O pins, along with two 16 channel relay boards. LED light bulbs are pretty lower power (compared to incandescent bulbs, anyway) so even though they’re 110 volts AC, 27 bulbs all on at the same time probably pulled less than 6 amps.

The image above represents my first attempt at layout out the controller, which I eventually abandoned. The screw terminals ended up not being a good idea. I would be pretty busy running Maker Faire so I assumed that I could find helpers able to strip wire, put them into the screw terminals, and get it all right. After attempting this myself on a small scale I decided that it needed to be even simpler, and clear enough that almost anyone could do the setup. So I scrapped the screw terminals. Around this time I also decided that running all of the power cords inside the PVC was going to be tedious and difficult, so with the decision to just run the cords on the outside (at least for this installation) I decided to just use standard household plugs. This would allow nearly anyone to just match up some numbers and plug things in. Simple wins!

The design process for the Giant LED Cube wasn’t too difficult. Doing this like this (designing, specifying parts, building, etc.) is pretty much my day job. The wiring was definitely tedious, and required at least one unexpected hour-long troubleshooting session due to a bad connection. I had a lot of help with the wiring of the lights from Adrian, and a lot of help with initial assembly from Becky. Without their help things would have taken me a lot longer. (Thank You!)

I think I’ve spewed enough about this project for one post (which I wanted to get out last month!) so I’ll end it here and get working on Part II ASAP.
