“These are all the files that I used to make a ATtiny85 circuit that controls a motor’s speed using a potentiometer, and also has indicator LEDs to qualitatively show the speed as you turn the potentiometer. One thing to …

“The goal here was two-fold; create something stylish that would look good when hung up on a wall, and ensure that all movements were as quiet as possible! I was inspired by some great existing projects that I have bookmarked …

“This is another one of the many unusual clocks you can see in some of my previous projects. IN-1 nixie tubes are relatively cheap. Nixie tube is an electronic device used for displaying numerals or other information using glow …

“This is a Nixie clock 3D wired in a glass dome. It is made with IN-12A (ИН-12A) Nixie tubes and an Arduino nano. This is inspired from a kit I bought a few years ago. I made some modifications …

“I am repeating myself lately but here is yet another thermochromic project because I really like the effect of these liquid crystal sheets. This time I wanted to make a large clock that you can hang on your wall. The …

“The goal of this tutorial is not to show how to build a specific KSP controller, but to show many of the common design choices and their pros and cons. The idea is to guide you to make your own …

“The Valden Heat Pump controller is an open source platform to precisely control heat pumps. This controller can be used for the automation of newly built Heat Pumps (HPs), as a repair controller for old systems or as control system …

“As a lifelong analog EE, I have built and used many DC power supplies starting with an LM309 5V regulator in the late 60’s. Then on to uA723s, various 3 terminal linears, and many switchers. At Analogic in the …
Project SonicSurface: Phased-array for Levitation, Mid-air Tactile Feedback and Target Directional Speakers

“We will build an array of ultrasonic emitters. It has 256 emitters arranged in a 16x16 grid operating at 40 kHz with individual phase control. It can focus the acoustic power at controllable positions to create dynamic levitation of small …
