Created by Tucker Shannon, the single pixel scanning camera uses a pair of stepper motors which directs the RGB color sensor (Adafruit TCS3472) in a square spiral for image acquisition: all powered by an Arduino Uno SBC. If you are interested in building your very own Arduino powered single pixel scanning camera, all you need is: Arduino…
Matthias Steinig, a German developer whose focus seems to be on the development of Lightning Network-enabled technologies to serve consumers, has created a new mechanism that allows e-bikes to be rented in exchange for payments on the bitcoin Lightning Network. The bike has a device that controls the flow of electricity depending on the payment that was made using the Lightning…
The maker Nikodem Bartnik has just created a 3d printed CNC machine that’s able to cut MDF and acrylic and can engrave aluminum. As for how well this CNC machine works, it’s pretty good. With the Gcode to cut an 80mm diameter circle out of MDF, this machine managed to cut a circle that was 80.02 mm…
Instructables user Sieuwe Elferink has just created a semi-autonomous kids’ four-wheeler. The Arduino powered Quad can steer itself within a set of lines, and stop for pedestrians and inanimate objects. For this project you will need the following materials: 3x TCRT5000 line sensor 1x HC-SR04 ultrasonic sensor 4x 5V relay 1x Windshield wiper motor 1x Arduino 2x tooth…
Pedalino is a new open source wireless MIDI controller which supports both iOS and Android operating system’s and offers a fully featured MIDI controller with three user profiles, and is capable of controlling up to 48 foot switches. That’s an impressive amount of kit for such a small device; usually you’d have to spend hundreds or even thousands of dollars…
