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]

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]

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]

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 now have http://www.rouecyr.org that redirects to my Circus/Cyr Wheel blog section. Cool!

Here is the start of a list of some Cyr Wheel Tutorial videos; many are by other people (ton’s by Mitch!), so I don’t take credit for the videos. As a reminder, here is info... [read more]

A bit over a year ago I started using my LED Cyr wheel v2. This version has LEDs embedded on the sides in epoxy, and it had been working pretty great until a show last... [read more]

Learn some cyr wheel manipulations when you are tired of spinning or get dizzy :) I go through some of the basics on how to do this trick. Be careful! One of the first times... [read more]

Cyr Wheel / Roue Cyr Tutorials: Rock start or side to side start, to waltz Here is another intermediate to advanced trick that took me a while to get. Really it was all about doing... [read more]

Here is a video tutorial on how to do the Superman move in a cyr wheel (roue cyr). This trick took me a long time to learn, and I’m still not perfect at it. Eventually... [read more]

I took some demo code and modified it to do a fire pattern in the cyr wheel:

This is a plot of the angular velocity vector when spinning in my cyr wheel. I took the gyro x/y/z value and created a vector (squared each value, added them, and took the square root).... [read more]

I have a accelerometer/gyro/compass combo in my wheel LSM303DHLHC, data sheet: http://www.pololu.com/file/download/LSM303DLHC.pdf?file_id=0J564 found via Pololu’s link: http://www.pololu.com/product/1268 It has been tough to figure out consistent data. First of all, I realized the compass has to... [read more]

Here’s some details on my cyr wheel inserts that I make (aka: roue cyr):

The next step for my project is to add 3d position support by determining what angle and how fast the wheel is spinning at any given moment. The chip is in the wheel; I just... [read more]

Another slightly longer video from last weekend. I have about 3 or so hours on it, and it seems to be holding up well!
