Time for another instalment in my irregular series of clock projects. (Or should that be “Time for another instalment in the series of irregular clock projects”?) In contrast with the extreme “blinkiness” of Clock One, in this article we describe how to build this single-digit digital clock: Once again the electronics of the clock will […]
When I was working on the Toy Magnetic Levitation project with a solenoid coil, I thought to myself, why didn’t I make a coil winder. So I took my times to build a simple coil winder based on GRBL firmware and it was made from PVC pipes. I’m willing to share how I made it, please check […]
Hello everyone ! Today I’m going to show you how I built this little kitchen scale during this lockdown ! It can measure weights up to several kilograms, has an included battery, a nice display and can even be turned into a connected scale thanks to the the ESP8266. I used a 20Kg load cell, […]
This project is bases on the internet radio by Ed Smallenburg. He did an awesome job in creating a working internet-based radio. He shared his coding and hardware on the world wide web so that people like you and me can learn from it. He shared his build on GitHub using the copyleft license. (It […]
This was my first animated Halloween prop. I found this witch at the local hardware store. It was meant to hang up by a cord and if someone came close to it, an infrared sensor would trigger the prop. The prop has LED eyes that would light up and it would trigger a voice tract […]
Maker Alessandro Grossi sent us this great DIY build for a 3D scanner built using a laser, a DSLR, and an Arduino controller. Allesandro is a Mechanical Engineer, holding a Ph.D. in product design. His day job involves helping designers and manufacturing firms develop and optimize products by means of FEM analisys and Computational fluid […]
About a week or so after Halloween last year (pre-COVID), I happened to be in Home Depot and back in a far corner bin were several Halloween items very heavily discounted. They were just trying to get rid of them as fast as they could. There were two life-sized animated knights that I got for […]
I’m not usually one to revisit a project after I’ve finished it, but I made an exception because the problems with the original design were making this device unpleasant to use. For those of you just now viewing this project, it is the second iteration of an iPod information screen I made for my girlfriend […]
If, like me, you have a pellet stove which does not indicate the low level of the tank, I suggest this little module which will beep when the reserve is almost empty. This gap is problematic because when there are no more pellets, the stove switches off and the ventilation still blows for 40 minutes. […]
Making a hardware synthesizer is a really fun and rewarding experience. But usually with a lead synth you would want to implement ADSR envelopes, multiple adjustable oscillators, multiple types of filters for each, polyphony et cetera et cetera. Those aren’t conducive to a beginner project, but it definitely isn’t impossible to make something that sounds […]
