I started thinking about ball juggling machines in the year 2015. I wrote about my first few attempts at creating them in this blog post from the year 2017. In 2018 I wrote another post about my then newest build. We’re now in the year 2020. And finally, the quest to get a machine to juggle a ping pong ball reliably has come to an end (as this current build is able to keep the ball bouncing for hours.)

Afterthoughts On Arduino Bouncing Ball on Plate Machine
Some years ago I started a Quest to get a machine to juggle. Some weeks ago, I yet again found myself working on a machine with the goal of getting a ball to bounce on a plate without falling down. And bouncing it does. But is the quest now finally finished? Is the holy grail of continuous ball-bouncing reached? The short answer is “No.” and I will probably not spend any more time on the current iteration of this DYI robotics nightmare.

Keeping a Ball Bouncing With 4 Mics
This is a PID controlled ball on a plate machine with the sole goal of keeping the ping pong ball bouncing for as long as possible. I have been trying to build ball bouncing machines for a while now. This is the newest iteration!
Scrappy Arduino Pen Plotter with Nema17 Steppers
After seeing a really neat commercial Pen Plotter on Youtube, I decided the time has come to build my own Arduino Pen Plotter using Nema17 Stepper Motors and readily available 3D Printer spare parts.

Adding Computer Vision to the Arduino Delta Robot
In the previous post, I wrote about how I decided to build an Arduino Delta Robot. In this post, I will show you how I added some simple Computer Vision to the project.

Arduino Delta Robot
This is a post about an old project I finished years ago. Maybe something good will come from looking back on what kind of decisions I made while working this monstrosity of an Arduino Delta Robot.
The Quest To Get A Machine To Juggle
This entry is about the quest to get a machine to juggle a ping pong ball.
I started thinking about a ping pong ball juggler 2 years ago. And it was around that time that I built the first one of them. it uses LED – Photo transistor pairs to “see” when and approximately where the ball comes down. I used 4 micro servos to move a wooden plate. It’s the machine in the first YouTube video.
