Back in 2012 I decided to make a V36 unicycle. I’ve kept breaking handlebars, mainly at the point where they attach to the seat base or the main seat post tube. The “T” unicycle design... [read more]

A few weekends ago I decided to do a long unicycle ride. Up to this point, the longest ride I did was around Lake Tahoe, which is no short ride topping in at over 70... [read more]

I figure it might be interesting to share my knowledge of how LED cyr wheels came about and the history of them. I may have gotten some dates and people wrong, so please feel free... [read more]

I want to record some video with my Canon 5D Mark III. I’ve done some basic experiments, but I really want to learn what the professionals do with this camera. First off, I upgraded to... [read more]

Oh, the Plug Bug! I have so much time and energy spent on this car, and it continues to this day.    In the past month, the bugs transmission has been in and out three... [read more]

A cool green geometric pattern on my LED cyr wheel.

Spinning cyr wheel with my buddy mario.   0.4s exposure, f/2.8, ISO 100, and a light focused on me:     1/8s exposure, f/2.8 ISO100:          

Some more experimental pictures I took tonight with my new LED cyr wheel (version three!): Original source image that I’m playing on the wheel: The wheel has 806 pixels on each side, and the bitmap... [read more]

I’ve succumbed to the pressures of social media and made a Facebook page: https://www.facebook.com/Corbins-Treehouse-258636957809592/      Please like it! I’ll post things on my blog and the page..

A quick test run on my latest LED cyr wheel.

Some improvements to the LED cyr wheel app! I am working on adding time codes to my timeline so I can more easily see the scale of things. Next will be at timeline marker, and... [read more]

The LED Cyr Wheel v3 is alive! A few initial pictures that I took with the help of my friend Mark from down the road. I need to do some more work on the wheel,... [read more]

I finally edited some footage I have of me rolling my LED cyr wheel. Here it is!

I needed a good way to control my new LED Cyr Wheel (v3). I previously had an app that would allow me to generate a pattern sequence. I’ve been expanding on it and created an... [read more]

I still really enjoy mountain unicycling. We used to have an annual event in Moab called Moab Muni Fest, but the organizer decided to call it quits. People would do an informal one for a... [read more]

Okay…the wheel is coming along! I haven’t posted a while — my internet was working poorly, and last weekend I went to Sedona (more on that in another post).   Notes to myself: Using the... [read more]

The LED Cyr Wheel moves along slowly! I screwed this little thing to my table so I could route the tubing. I used my same routing jig as last time:   Chips in a little... [read more]

My drilling/tapping jig to hold the wheel steady while I drill and tap the inserts:   I put a coat of paste wax on the inserts to make them slide easily: All the pieces during... [read more]

Okay! I discovered that 1.240” for an insert is too thick. I had to do several passes with a sanding disk to take them down a bit. I’d say 1.230 is more close to the... [read more]

Fresh rolled wheel:   Marking off the circumference with a flexible tape measure: After cutting it into a 5 piece wheel: Some of the curves where a little under-bent, so I rolled a few through... [read more]

“Making Donuts” is Bill Roberts, a “Cyr Smith” [term coined by Jesse], says when rolling cyr wheels.  So, I’m “making donuts” right now for my next wheel. This started by fixing up my harbor Freight... [read more]

My boards arrived from OSH Park today. This will combine all the necessary cool stuff:   A few days ago I got my new LEDs (144 per meter). A month or so ago I ordered... [read more]

I’ve been obsessed with making another LED cyr wheel that has improvements over my last one: Persistence of Vision (POV), better pattern sequence creation, and Bluetooth LE support.  I’m currently working on a PCB that... [read more]

I’ve been using the Adafruit LE friend to do some data transfer tests. With the basic setup, I was sending 1 kB of data in about 9.5 to 10 seconds. That is horribly slow! About... [read more]

I’m working on adding bluetooth support to my LED cyr wheel.  A long time ago I picked up an Adafruit nRF8001 breakout board — I was worried it was too big to fit in my wheel,... [read more]

I wanted to touch up some of the areas next to my newly remodeled bathroom, and the laundry room needed a new utility sink. The plastic piece of crap I had was junk and I... [read more]

Oh boy… My bug needed new brake pads. I go through them crazy fast, as I drive down the famous “Highway 17” on a daily basis and my car doesn’t do any re-gen braking. This... [read more]

Stories from the driver’s seat. I have been pulled over at least ten times by the cops. It has become less frequent the past two years, although part of the reason is probably because I... [read more]

Stories from the driver’s seat. So, this happened about three years ago. I was driving the bug to the Summit Store in the Santa Cruz mountains, and pulled into the parking lot. It was a... [read more]

Stories from the driver’s seat. In the past four or five years I have been pulled over by cops a lot. I always get set on my way without a ticket; so far I haven’t... [read more]

Stories from the driver’s seat. This is something that happened about four years ago, and the picture below is from 2011.    The California HOV white stickers: the privilege to drive solo in the carpool... [read more]
