NO NEED FOR SPEED WITH THIS ARDUINO-BASED INKJET PRINTER

When it comes to computers, it seems like the only thing that matters is speed. The more the better, in general, and the same applies to peripherals. We want the fastest network adapters, the fastest video card, and the fastest printer. So why in the world would anyone intentionally build a really slow inkjet printer? For art, of course. At least that’s the story [HomoFaciens] tells us in the video below. H ...

Motion Tracking Face

https://youtu.be/Nqh3Ej8qfTU Meet Chartreuse! Chartreuse's face follows you when you walk by. When she sees you, her eyes turn yellow and she gets a happy expression in her eyes. As you walk away, her eyes change to blue and she sadly turns away. Chartreuse is powered by an Arduino Uno, two servos, and a stepper motor and a couple of addressable LEDs and constructed from a few pieces of 1/8" hardboard. Supp ...

Color Instrument

This a simple Arduino/3D printing project about colors and sounds. I made this device or as I call it ‘color instrument’ for activity for kids. It’s fun and it’s a good conversation starter about physics of colors and sound. The most interesting fact about colors, in my opinion of course, is that pink color doesn’t exists in physics. I know, I know, you all thinking it’s a lie, but next time you look at the ...

Alexa Controlled Dog Feeder

This is our dog Bailey. She's part Border Collie and Australian Cattle Dog so sometimes she's smarter than her own good, especially when it comes to telling time and knowing when she should be eating dinner. Typically, we try to feed her around 6 PM but this isn't always easy if we're away from home. The Alexa Controlled Dog Feeder was created as the perfect solution to feeding Bailey while we're away from ...

AUTOMATING HAND SANITIZER — IF YOU CAN FIND ANY

We once saw a Romeo and Juliet production where the two families were modern-day mob families with 3-piece suits and pistols. If they made King Richard III set in this week, the famous line might be: “Hand sanitizer, hand sanitizer, my kingdom for hand sanitizer!” Even if you have a supply stashed in your prepper cache, you have to touch the bottle so you could cross-contaminate with other users. Public pla ...

Inverted Pendulum: Control Theory and Dynamics

https://youtu.be/xwXPipYmJ9A The inverted pendulum is a classic problem in dynamics and control theory that is generally elaborated in high-school and undergraduate physics or math courses. Being a math and science enthusiast myself, I decided to try and implement the concepts that I learned during my classes to build an inverted pendulum. Applying such concepts in real life not only helps strengt ...

3D Printed Robot

https://youtu.be/AJ1TfieZ6Dg The nice thing about 3D printing is that it makes building robots easy. You can design whatever configuration of parts that you can dream up and have them in your hand virtually right away. This allows for rapid prototyping and experimention. This particular 3D printed robot is an example of that. This idea to have a walker bot that shifted its front center of balance is one tha ...
