Low-quality wireless audio transmission with Arduino

After considering the price of helmet-mounted headsets for motorcycle or moped use, YouTuber GreatScott! decided to try making his own. His walkie-talkie prototype consisted of two Arduino Nano boards, using nRF24L01+ transceivers and a small speaker for PWM audio output. After a test demonstrating wireless transmission, the design was transferred to custom PCBs, programming their […]

Mover3D is a 3D-printed moving light for your desk

LEDs are fun, and RGB(W)s adds a new element to things, but what if you want a light that can also move by itself? The Mover3D does just that as a pan/tilt system controlled by the DMX512 communication protocol. You simply feed instructions in via any standard lighting console, and it dances around under your […]

Visualizing magnetic fields in three dimensions with an Arduino magnetometer

As humans, we can’t detect magnetic fields, but we take advantage of this phenomenon every day in the form of motors and various sensors. Even electrical wire produces a field when current flows through it. You can perceive magnetism with a compass, but if you want to visualize it in three dimensions, maker ‘amamitof7’ has […]

Plywood printer uses a unique mix of manufacturing methods

Sure, we’ve seen low-cost DIY 3D printers with wooden frames before, but not a 3D printer that actually ‘prints’ wood. That’s exactly what Shane Wighton and his Formlabs hackathon team have done. (Although probably more along the lines of a hybrid additive/subtractive CNC machine that makes parts out of 3/4″ particleboard.) The device first cuts […]
