Developed by students at the California Institute of Technology, Poseidon is an open source alternative to commercial syringe pump and microscope system. The Poseidon microscope consists of a Raspberry Pi, touch screen module, and commercially available digital microscope housed in a 3D printed stage. This device offers a large and clear view of the object…
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…
Set consisting of a stepper motor driver based on the ULN2003 chip and a 4-phase stepper motor. Equipped with 4 status LEDs for each phase of the motor, the driver is controlled via the 4 input pins IN1-IN2-IN3-IN4 with Arduino / Fishino or other microcontrollers. Power supply: 5 Vdc – 500 mA, driver dimensions…
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…
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…
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…
The Etch-A-Sketch was released by The Ohio Art Company in 1960. The popularity of the device is sort of interesting because it has lots of annoying problems: knobs only move the cursor up/down/left/right. Diagonals and curves require a steady precision that most children 3+ simply don’t have. you can’t draw two objects that are not…
The Shy Machine is a motion activated, sound reactive, environmentally adaptive and arduino-powered kinetic light sculpture. When it detects motion via a PIR sensor, the shell-like robot takes a reading of the ambient sound level using an internal microphone. If things are sufficiently quiet, it opens up using a stepper motor and lead screw, revealing…
[youtube id=”FxAPxaIH_Hk” width=”620″ height=”360″] But what is uStepper? In short, uStepper is a product, improving performance of a motor type called “stepper motors”. Stepper motors are used in a wide range of applications where you have to move something, a certain distance, precisely! For example, they are used in your inkjet printer for moving the…
Artists, painters and makers looking for a way to automatically mix paint to an exact formula may be interested in a new automated paint mixing machine called the Mesomix. This machine, which resembles a very nice 3D printer in design, sucks colored paints from four containers in order to combine them into whatever color of…
Cosmos enthusiast Jason Bowling’s come up with a very straightforward way of focusing his Celestron 127SLT with a Raspberry Pi Zero SBC. “One of the tradeoffs with the mid-price Celestron 127SLT is that it shakes rather badly when you touch it, and takes several seconds to settle down. I’m focusing using a Bahtinov mask and…
After finding that purchasing a tracking device for his satellite dish would be quite expensive, YouTuber “Tysonpower” decided to simply build one himself. He made it with 3D-printed parts and extruded aluminum that uses a pair of NEMA23 stepper motors for movement. While it doesn’t quite work with the dish itself due to its offset…
