“Now it’s time for something completely different. I know this website is mainly vehicle focused (hence the name “Motors” in the name), but like most people, I have another hobby – electronics. Now, sometimes these two hobbies intertwine, which will …
“alles is a many-speaker distributed mesh synthesizer that responds to control signals over WiFi. Each synth supports up to 10 additive sine, saw, pulse/square, noise and triangle oscillators, a Karplus-Strong string implementation, and a full FM stage including support …
“Pulse oximeters are standard instruments for hospital settings. Using the relative absorbances of oxygenated and deoxygenated hemoglobin, these devices determine the percentage of a patient’s blood that is oxygenated (a healthy range being 94-98%). This figure can be lifesaving …
“In this tutorial we will learn how to make an Arduino based RC receiver. Since building my DIY Arduino RC transmitter in one of my previous videos, I got a lot of requests from you guys, to make a dedicated …
“Time for another project with a super-low-cost microcontroller. But what to design? Ever since seeing a project where a $0.03 MCU controls $40 worth of intelligent RGB LEDs, I have been wondering whether this is the right place to …
“I always liked the design of the Wii’s Nunchuck controller. But normally you can only use them if they’re physically wired to another device called the Wii Remote. However, with some hardware and software tinkering and time, it …
“A cool Newton’s cradle made from ping pong balls containing WS2812B LEDs. This project emulates a Newton’s cradle using light to demonstrate the conservation of momentum and energy. The original project was created by TecnoProfesor and can be …
“There’s a lot of arduino/ESP32 clocks going around, but do they use those nice and crisp OLEDs? I’ve been experimenting with arduinos and ESP32’s for a while now, but I never made it to a finished …
“I recently got introduced to the concept of binary watches and started doing some research to see if I could build one for myself. However, I was unable to find an existing design that was both functional and stylish at …
“Use the latest ATtiny processors in the Arduino Environment. These have the memory capacity of ATmega chips in smaller and cheaper packages. You may be familiar with the ATtiny series of microprocessors from Microchip such as the ATtiny85 or ATtiny2313 …
