Electronics Blog
It s been 5 years since I posted something. Blogs going silent; It s a common thing, isn t it? And this blog was following that trend for a while. So what was I doing all that time? I ll give you the short summary: kid was born, made an indie game, made another indie game, changed jobs. So Continue reading Work on Next Machine The post Work on Next Machine appeared first on Electron Dust .
Roughly three months have passed since I wrote my initial post about a machine I call The Octo-Bouncer. What has happend since then? In this post I talk about what parts of the machine were updated. Why they were updated and what kind of stuff the machine is able to do thanks to these updates. Continue reading The Octo-Bouncer: Advanced Bouncing Patterns The post The Octo-Bouncer: Advanced…
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 Continue reading The Octo-Bouncer The post The Octo-Bouncer appeared first on Electron Dust .
Can we get a machine to throw a ball with good precision? That s the challenge we re facing in this blog post. I gave it a shot. In this post, I go through the building process and describe what I ended up with. So what did we end up with? Here s a YouTube video of the Continue reading Ball Throwing Machine The post Ball Throwing Machine appeared first on Electron Dust .
I bought a Benbox CNC1310. As of now, I did some simple wood milling jobs. I am very pleased with the build (all aluminium/copper/metal no plastic parts whatsoever.) The only negative aspects that come to mind are the limited workspace (130mm x 100mm, hence the 1310 ) and the cheap clamps (the things to hold Continue reading The Benbox CNC 1310 The post The Benbox CNC 1310 appeared first on…
For some reason, I found myself wondering about an old problem I did at university. It was about finding the velocity function of a falling raindrop with air resistance proportional to the velocity squared. In exploring a way to get to the solution, we wade into the sticky territory of differential equations. Read more here: RaindropWithAirResistance The post Solving the Differential Equation of a…
Talk about cheap stepping motors and there s a good chance someone will mention the 28BYJ-48 . Or maybe he or she will not remember the part number and say something along the lines of That 3 dollar stepper used in air conditioners! You know! B28 something! Truth be told, it doesn t get much cheaper than 3 dollars. Continue reading ESP32 Micro Robot Arm The post ESP32 Micro Robot Arm appeared…
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 Continue reading Afterthoughts On Arduino Bouncing Ball on Plate Machine The post Afterthoughts On Arduino Bouncing Ball on…
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! How does it work? The location of the ball is calculated Continue reading Keeping a Ball Bouncing With 4 Mics The post Keeping a Ball Bouncing With 4 Mics appeared first…
This entry is about a small stepper robot arm I made a while ago. In this post, I will first talk a bit about how I built it and what my thoughts were while doing so. After that, I will show some moving footage of what the thing is able to do. A Small Stepper Continue reading Small Stepper Robot Arm The post Small Stepper Robot Arm appeared first on Electron Dust .
