Whew! Hey folks, I’m back. It’s been over a month since my last post, but don’t worry, things are going good, they’re just going a lot, or there’s a lot going on, or something like that. I’ll just update everything.

First of all, I spent a week at the beach. The ocean beach! We went out to Maryland and I was actually out of the office for five whole days! I barely worked at all, besides a phone call and a bunch of emails to keep thing moving for Maker Faire Milwaukee.

Oh yes, we’re just 60 days out from Maker Faire Milwaukee and there’s a heck of a lot of things to do this year. I’m also headed to Maker Faire Detroit this week. (And there’s a chance I’ll hit up Pittsburgh and/or Orlando as well.)

One of the projects I’ve been working on for Maker Faire Milwaukee is called NoiseMaster 3000 which will consist of a bunch of DIY noise making devices. Here’s a few in progress.

I’ve been combining 3D printed parts with scrap wood and really enjoying the process. I’ve been thinking a lot about how the two materials fit together, and I’ll probably write up some thoughts on that later.

Oh yeah, I also went to Kansas City with a Wienermobile. That was exciting. Find out more! Meanwhile, we’re still working on our no-weld vehicle, sometimes using wood where maybe wood doesn’t belong. Oh well! Also, photos from Kansas City!

I saw Wonder Woman and The Big Sick and they were both great movies. I’ve also been trying to get caught up with Doctor Who, but besides that I still don’t watch very much TV. (I haven’t seen Game of Thrones or House of Cards or Breaking Bad. I hear there’s a new Star Trek showing coming out soon!?)

I’ll be speaking at the Inventors & Entrepreneurs Club of Kenosha & Racine next month on the topic of Arduino. I should probably prepare for that. Also, the mayor of South Milwaukee wants to meet with me, because of something I posted on Facebook. (Don’t worry, I’m not in trouble!)

Okay, well… that’s all I can think of for this update. You can follow me on Instagram for previews and peeks at my current projects, and I sometimes post things on Facebook, as well.




I attended the Bay Area Maker Faire (sometimes referred to as “BAMF”) and while I spent most of my time in a booth helping explain what Crazy Circuits were, I did get some time to run around the Faire and see a few things.

Robot Dance Party

I also got to meet people I may not have seen for a few years, or not met at all, and only know through online interactions, so that was awesome. I’d provide a list of folks but I’m sure I’d forget a few!

So here’s some photos and some notes about photos. As mentioned, I did not get to see everything, and being such a crowded event there would be times I’d really want to talk to someone but it would have meant waiting around for other people to finish talking, and I had limited time! Here we go…

I was really excited to see Robot Dance Party in person. I had read about it (him?) years ago, and it was totally unexpected to come across the #RobotDanceParty while walking around the Faire. It’s as simple and silly as you might expect. Here’s more info on the Dancing Robot that Parties.


While everyone was eating paella on Friday night I had to find a restroom and wandered down this back walkway surrounded by these weird and creep robot-type things with uncanny valley faces. It was strange, unsettling, and awesome.


There’s a question those involved in the Power Racing Series ask… What Would Bill French Do? In this case, the answer is, show up Saturday morning with a car that is totally not ready to race, and isn’t even done being built, and solder up a motor controller while someone else works on finishing the actual car build. That’s what Bill French did.


These portable shadow boxes were simple and fun, and reminded me of an activity I’d see in BBCM’s Be A Maker space.


This spinning fire thing was interesting, and I saw it every time I ran from the booth to the restroom and back again…


I call this “French Cleat All The Things!” and wanted to snap a photo to remind me of a good way to organize a creative space…


I got to meet Paul Stoffregen of PJRC, though since my voice was shot I’m not sure he knew who I was or the fact that I’ve bought hundred of Teensy boards from him. Anyway, he had this super-cool kid-proof synth at the PJRC booth.


I took this photo to show to a few people at Milwaukee Makerspace. Specifically, Bob and the people who made the coin shrinker and other crazy devices. Once again I didn’t get to talk to the makers or spend a lot of time looking at the thing… I had to keep moving!


This was a large skateboard. It was so large someone said you could use a normal skateboard to get from one side to the other. They had cast the wheels using Urethane. I was hoping they had cast the trucks, but they were actually 3D printed by some company. (The guy I talked to didn’t know what company.)


I actually got a little bit of time at the Power Racing Series racetrack and helped marshal a race. This cardboard car was pretty awesome to see. Underneath was basically a Crazy Cart and it drove sideways a lot.


The minion car that was eating a banana and farting bubbles was highly entertaining. I guess the team destroyed the original (nearly stock?) Power Wheels car the first day and had to go buy another one for the second day.


From what I could tell this was a sort of “BattleBot Arena” where you could make a cardboard robot and then see it destroyed by a robot with a rotating saw blade. At least that was my guess after watching it for approximately 60 seconds.


The had vintage computers running vintage video games, and kids loved it. Is that a Commodore 64!?


There were giant light-up inflatables in the Dark Room and you could walk and crawl among them and there were pretty cool.


I also loved these colored squares. Simple yet effect method of working with light in the Dark Room.


The Howtoons table had some great stuff. I believe they’ve moved from just books & comics to a subscription & kit model. If you’ve got a kid-maker this looks like something they would love. (I loved the cardboard ukulele!)


In the tent I was in a group was building a giant Makey Robot using balloons! Luckily I posted a photo of it and my pal Dan from Rochester, New York identified the group as Airigami, and said he saw they at Maker Faire New York.


I got to see Lenore and Windell from Evil Mad Scientist Laboratories. Each of them stopped by to see me (separately, because, you know, someone has to stay at the booth) and then later I got to see them both at the booth for a few brief seconds. While I was taking this photo a guy came up with a friend and shouted “This is the absolute coolest thing here!” in response to seeing the MOnSter 6502. It was indeed beautiful.


I heard you like nightmares so we took an old Chuck E. Cheese robot and ripped its face off and then turned it on to freak you out. You’re welcome!


I got to run around with Karen for a bit at the end of the Faire and we saw as much as we could in a short amount of time. And of course… MagaBots! (Though I totally missed the part where Miles proposed to Jen.)


Robin demonstrating how we all felt at the end of Maker Faire. Exhausted. Thanks to everyone I met and apologies to everyone I did not get to meet! I hope to make it back again in the future!


Maker Faire

I’ve been to a lot of Maker Faires in the past five years, but it’s mainly been in the Midwest (Detroit, Kansas City, Madison, Fort Wayne, and of course, I help produce Maker Faire Milwaukee) though I did make it out to New York a few years ago, and Washington D.C. for the National Maker Faire last year…

But I’ve never been out to Maker Faire Bay Area… until now. Yes, friends, I’ll be out there this time around, and I hope to see you there.

I won’t be wearing my Maker Faire Producer hat though… This time around I’ll be working the booth for Brown Dog Gadgets, who just completed their (successful) Kickstarter Campaign for Crazy Circuits, which is a LEGO Compatible modular electronics platform. Yes, LEGO bricks and microcontrollers mixed together. Fun!

I’ve done a number of projects for Brown Dog Gadgets over the years, and while I didn’t have lot to do with the new Crazy Circuits project, I pitched in where I could with a few ideas and a bunch of code. It’ll be exciting to share the work with a large crowd! (And exhausting, from what I hear. Even though Maker Faire Milwaukee is the largest free Maker Faire in the U.S., the Bay Area crowd still has us beat!)

(I’m not sure if we’ll make it to #BringAHack or other fun events, so if you want to meet in person, look for the Brown Dog Gadgets booth.)


Les Yeux

One of the pieces I displayed at Maker Faire Milwaukee in 2016 consisted of two monitors showing a pair of eyes. I was (slightly) inspired by Ben’s Video Wall of Terror.

Les Yeux

I started by filming Dr. Prodoehl to capture the movement of her eyes. The crop lines show where I planned to crop the single video into two separate videos. I also used filters on the videos to get the old TV scan line effect and add a bit of distortion. (The cropping is for a 4:3 aspect ratio display to be compatible with the old computer monitors I had on hand.)

Les Yeux

The two videos were then exported and one was trimmed to be about a half second shorter than the other one. Since the installation would be running for two full days this meant that we’d see some interesting time drifts between the two videos.

The videos were played using a pair of Raspberry Pi Zero single board computers. Like nearly every installation, there were problems involving technology, this time I think it was a bad SD card, but I quickly swapped it out and got up and running again.

Here’s a short video showing Les Yeux Times at Maker Faire in 2016, along with the two videos that were used.


Apple Wait...

At Maker Faire Milwaukee in 2015 I presented a piece titled Apple Watch, and at least one person enjoyed it enough to make me think about creating another piece utilizing the same concept, so for Maker Faire Milwaukee 2016 I presented Apple Wait….

Apple Wait...

Apple Wait… (like Apple Watch) consisted of a Raspberry Pi Model B connected to an Apple Monochrome Monitor from 1988. Instead of just attaching the Raspberry Pi to the monitor with some gaff tape, I added in one more reference to technology, an iPhone box.

Apple Wait...

It seems the box for an iPhone is just the right size to house a Raspberry Pi Model B. Interesting enough, the iPhone 4S and the Raspberry Pi Model B were released about the same time frame. They are very different devices, with different goals, aimed at different audiences. Why not merge the two together? Technology is interesting!

Apple Wait...

For Apple Wait… I took a busy indicator cursor from the olden days of computing on Apple devices and brought it into the modern day, but made it 8-bit and low-rez, because retro is in. If you’re interested in learning more about old things, check out Where did the loading spinner originate?, The Design of Spinning Indicators, Spinning pinwheel, History of the Mac Spinning Wait Cursor, and just for a laugh, The Marble of Doom.

Apple Wait...
