5c practice for 6c passing (juggle, pass, wait, receive, juggle...) was a bit hard for T, only worked sometimes.

534534 and back to fountain didn't work well today, took way too long to get it once from each hand.

Got a pretty good round of 531

Weave, T feeding. S was watching and instructing.

(With T, M, S and S2)

Mr inside Mr outside weave. First with S and T next to each other, then with S on the other side of the weave. I am starting to get the turning part now.

W feed with 2 extra clubs (2-count/4-count on doubles) didn't quite work, but we got a few passes in the configuration we started with (M and S2 on the ends)

3p[4,3]2 didn't work

3p[4,3]2 vs 3-count did work, though.

(With T and S2)

2-count/4-count feed with walking

pps/3-count feed with walking, only got 1 walk on most attempts, sometimes two.

Bruno's Nightmare

10c feed, we took turns feeding. Got a few passes with S2 feeding, a few more with me feeding, T did early triples with pirouettes when he was feeding (though that only worked sometimes).

3 balls, 25 minutes

I didn't actually feel like juggling tonight. Not until I picked up the balls, that is. The main reason that I even did that was that I didn't want to break my "not a whole week without juggling since 2015". Well, as soon as I picked up the balls, I enjoyed it. Decided already before I started that I was just gonna do whatever I felt like, no serious practicing for a specific goal or anything like that. Should juggle that way more often.

I got a few catches of 3b box today! I think it might have been 8 catches on the best round. Definitely got 6 a few times (and back to cascade some of those times, too). Haven't done that before. :)

vision research, 1 minute

I built a Claude Shannon Juggling Machine. Instead of using physical objects, I built this machine virtually. This is written in Python 3. The UI and some of the functions use the computer vision software library OpenCV. Like Scott said in the original post, the fun of this device is not in building it. The interesting part is tuning the device so that it juggles.

This program is object-oriented. The balls are the objects. Each ball object has two attributes, (1) a tuple to describe the ball's (x,y) coordinates, and (2) a tuple to describe the ball's velocity vector (speed and direction).

Several functions allow the ball to interact with the environment. These functions move the ball, apply gravity, bounce the ball off an object, etc... In the main loop of the program, all of these functions are called on the balls to produce juggling.

The machine is tuned by adjusting the parameters. Parameters are defined before running the program, or changed during runtime using the keyboard. The most important parameters are speed and rotation. Each number of balls requires a specific combination of speed and rotation to juggle. Graph of number of balls and, speed and rotation.

To find these values, I tuned the machine during runtime. It was tedious to tune the machine, and I am searching for a way to mathematically derive the parameters that will produce juggling for n number of balls. Is there a formula that relates the number of balls and the combination of speed and rotation?

Please try this out for yourself:
