VIDEO FACE [AVM-312]

video-face-01

One of the projects I built for Maker Faire Milwaukee in 2019 was VIDEO FACE [AVM-312] which is a companion piece to AUDIO FACE [APC-320].

This piece came about because my sister gave me a box of old security cameras. Specifically, analog video cameras. I brought them to Brinn Labs and hooked them up to one of my displays, and they worked fine. They just need a 12 volt power supply and they have composite video out. If you mix the two signals from two cameras together into one output you get a garbled and mixed signal, but if you add in a resistor and potentiometer, you have a way to control the amount of signal that the second camera leaks into the stream to mix with the first camera! (It’s an analog video mixer.)

I considered adding resistors and potentiometers to both cameras but for a standalone exhibit that would have allowed people to dial it down too much and the projector that was connected would probably have gotten confused and lost a recognizable signal and just shown “NO SIGNAL”, so I went with one camera full strength and the other variable.

Construction of this was very slapdash, using scrap wood I found at Milwaukee Makerspace one night. As yes, it’s supposed to look like a face, I mean, it’s in the name, it’s got two eyes looking at you, a nose with controls and a mouth, sort of…

During Maker Faire I had it hooked up to a projector that had analog video input. (Yeah, those are probably getting harder to find, but I have some interesting old equipment.) For other events I just used one of the small television sets I have on hand.


I loved doing these quick and dirty interactive projects, back in the old days, you know, before the pandemic.

Maker Faire Orlando 2019

I managed to attend seven Maker Faires in 2019, including Elkhorn Mini Maker Faire, Maker Faire Miami, Maker Faire Kansas City, Maker Faire Detroit, Maker Faire Milwaukee, Madison Mini Maker Faire, and Maker Faire Orlando. For three of those I served as a Producer or Producer in Residence, and for the others I attended as a Maker, either representing Milwaukee Makerspace, Betty Brinn Children’s Museum, or taking part in the Power Racing Series.

Pictured above is a shot of the crew for Maker Faire Orlando. They are an amazing bunch of volunteers who work their butts off to put on an amazing event. I’m proud to have been able to join them the last three years and assist in any way I could. And besides all the local folks who help out we had guest Producers from New York, Pittsburgh, and Milwaukee all helping out, each bringing a unique perspective to the group.

(Note: We’re missing a few valuable crew members in the photo because they were busy with Robot Ruckus, which is an amazing event that happens inside another amazing event. Amazing!)

I tried to get a little time to run around with my DSLR and capture some photos, and I’ve got a whole album, but here’s a few worth sharing… Above is a creepy doll, or to be more precise, one of the Deviant Dollz. I don’t know that I’d ever purchase one of these dolls, but I loved seeing them, and if I ever have to shoot a horror film, I know who I’m getting the props from.

Our old pal Matt Stultz was there with Prusa, the company and the man, and people really liked finding out more about what they do. Also, I learned that bringing your Prusa printer to a Maker Faire so Josef can autograph it is a thing people do.

Gary the Snail (along with Aren) made it for the Power Racing Series finale, and took the title! Many PPPRS friends were there as well, including Jim, Patrick, and racers from around the country. We also got to test a new water barrier concept on the track this year, which was fascinating and fun.

It’s always good to see Jeremy Cook and his latest strandbeest contraptions. If you haven’t met Jeremy yet, check out his videos. He’s one of those makers who seems to keep busy all the time.

Hey, if you’re gonna throw a Maker Faire you should have a DJ because they make sick beats happen, they make people smile, and they make everyone have a good time. At least that’s what the.kd.queen managed to do. She even handed the mic over to some crazy futuristic robot for a while… magical!

Dodecahedrons

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 Connector on PrusaPrinters.)

dodecahedrons-colors-01

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 [APC-320]

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…

audio-face-5033

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.

audio-face-4992

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.

Maker Faire “Space Invader” Shirt

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.)
