This DIY Attack Dyno Project is designed to fit in the dash of a car and will give you measurements such as horse power and torque based on just a few car connected sensors. “The Attack Dyno is a convenient and affordable way to bring an attack timer and dynamometer right to the comfort of your own vehicle. The whole design is built to fit right into the space
This Nixie Alarm Clock project gets the Time Updated via GPS. Not only is there GPS to get an accurate time, this clock also has an SD card that is used to play audio files. “The firmware for the clock is written in C using Eclipse C/C++ with the AVR Eclipse plugin with avr-gcc and avr-libc 1.8.1 Since the GPS module provides the time in UTC, I need to
CNLohr has been playing with the inexpensive IOT device for quite a while. Check out the ESP8266 Brodcasting Analog TV while running a Web Server. Hard to believe that this small chip is only a few dollars in small quantities. If this chip is in a IOT light bulb or doorbell this thing would be seriously be underused. That would be just like using your brand new android phone to
GreatScott! has created a great video showing how Brushless DC Motor and Electronic Speed Controllers work. We see lots of these in quadcopters these days. The basic DC motor is popular and simple to control but as more things are using brushless motors it is nice to know how they work. “Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous
If you are looking for an interesting FPGA project this FPGA RGB LED Matrix Driver Project looks interesting. There is a great overview of how the project was designed. Interfacing to the large display is quite complex but by doing it using a FPGA they have control over every aspect of what the hardware is doing. The current design uses the display as dumb output which gets what is to
idogendel.com used an Arduino and some shift registers to create this nice looking Christmas Tree Ornament. The LEDs shine through the holes in the box and are diffused using the paper front. “I built this little Xmas-tree DIY Arduino project to demonstrate the use of the 595 Shift Register ICs (see link below) as output port expanders: 12 bi-color LEDs are handled using three 595’s and just three Arduino
Laser Duel is a project made by XiaoXing Zhao, Fred Kummer and Douglas Katz for their ECE 4760Â Final Project. The two guns use Nordic nRF24L01 radio transceivers to talk back to a base station which monitors the game play and keeps score. Each gun has some visual indications so the players can see what the health is and there is also a speaker for some audible indications for
