James Bruton built a pipe organ using a Henry vacuum cleaner, a canister vacuum with a silk screened face. He adapted cheap children’s plastic recorders to a Henry vacuum cleaner with a few 3D printed parts, some servo-controlled valves, and a bit of plastic tubing, allowing it to play a full octave and the melody…
If you wear a self-winding watch, I’m sure you’re aware that watch winders are generally very expensive, or cheap and noisy. So Kristopher Marciniak decided to hack an inexpensive winder replacing the stock motor with a stepper, and using an Arduino along with a Trinamic SilentStepStick driver for silent and well-controlled movement. “What I really…
James Bruton has just created an Arduino-powered robot that is able to boil an egg for you (for now), but he’s planning to expand its repertoire as a sort of ongoing theme/project. The robot first holds an egg in a metal basket and rotates it over a nearly boiling saucepan using a servo along with…
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…
How To Mechatronics has come up with a bender that not only twists wire left and right, but can rotate to create three-dimensional shapes. The 3d wire bending machine is powered by an Arduino Nano, which controls three stepper motors for wire manipulation via DRV8825 driver boards. A servo motor is also implemented in order…
If you are planning your holidays, for sure this project will help you to solve a big deal: watering your plants. Also if you aren’t going on holidays, this system can avoid you to waste time in hand watering. In fact it is designed to take the hassle out of watering, by watering only when…
“The device features an ultrasonic sensor for measuring the distance to the nearest object, an accelerometer for measuring the angle with respect to the ground, an LCD display for showing the results and a custom designed PCB on which all components are connected.” Combining an ultrasonic sensor for range measurement and an accelerometer for measuring…
At the core of any assistive technology is finding a way to do something with whatever abilities the user has available. This can be especially difficult in the case of quadriplegia sufferers, the loss of control of upper and lower limbs caused by spinal cord damage in the cervical region. Quadriplegics can gain some control…
If you are a musician and if you lose your concentration when you have to flip through sheet music while playing, PartitionsDuino might be just the thing for you. The maker Maxime Boudreau has created a 3D-printed pedal with an Arduino Nano inside which allows you to control PDF sheet music on your laptop with the tap…
This particular (un)locking system, created by Rudec Technologies, is still in the prototyping stage. Actually it is hosted on an Arduino Uno, but the maker is planning to migrate the system on one ESP32 board to develop a small web server and allow for user connections for administration/monitoring of the system. The system uses a…
How many of you have a Roomba Vacuum Cleaner at home? I always wanted one of these, but I never bought it. Maybe now I have another option…I can build it! The maker theking3737 created his own robotic vacuum cleaner as part of a school project. He was responsible for the hardware design, while a…
Youtuber Bob Clagett is a huge fan of 80’s toys and movies. Inspired by Transformers he decided to realize his dream: build his own life-sized Optimus Prime ion blaster. Now, after hours of 3D printing and finishing, he finally has something worthy of that universe. Inside, sound and lighting effects are controlled by an Arduino, which…
