An Arduino Mega based bike dashboard
In this project we will see how to make a simple bike dashboard that allows you to view speed, turn on rear and front lights and enable turn signals. The system is based on an Arduino Mega which controls two 1.3 “OLED displays to view data, several segments of WS2812 led strips used as lights…

Do-It-Yourself Frequency Counter
This project allows you to create a frequency counter with excellent precision and low consumption thanks to the use of a 32768Hz quartz. The project is based on a BluePill with STM32 microcontroller. The latter receives a 10MHz clock which is multiplied to 70MHz by the internal circuit of the microcontroller and uses a 32768Hz…

Measuring wheel
In this project we see how to build a measuring wheel designed to be used over distances where rulers and tape measures are no longer practical. Even if it uses a rotary encoder with only 20 steps per revolution it can still provide good quality results by measuring, for example, the size of a room….

Taking a Rotary-Dial Phone Into the Future
When I grew up we only had rotary dial phones for many years, I love them, love the sound they make and been wanting to take one and make it into a mobile phone for many years. So I was super happy when a good friend (thanks Ilanit) told me she got one for me….
