The tiny board designed using A3979 IC from ALLEGRO which is complete micro stepping driver with built in translator. The translator is the key to the easy implementation of the A3979. It allows the simple input of one pulse on the STEP pin to drive the motor one micro step, which can be either a […]

WiFi controllable motors for your many projects. An Open Source platform that anyone can use. Using our motors is as simple as joining your motors network (or adding the device to an existing network) and controlling it with any of our apps, its built it webpage, or just raw JSON packets. Our motors are made […]

Ken Shirriff did a teardown of a Sonicare electric toothbrush: The photos below show the top and bottom of the toothbrush internals. I expected to find a simple, low-cost mechanism, so I was surprised at how much complexity there was inside. The vibration mechanism (right) is built from multiple metal and plastic parts screwed together, requiring […]

baelza.bubba @ instructables.com show us how to build a DC motor direction controller using L293D. I designed this DC Motor Direction Controller so that I could give direction control to DC motors that I am building into mini tools (drill, lathe, table saw, solder smoke extractor, etc.). While, I don’t need direction control for all […]

baelza.bubba @ instructables.com build his own PWM controller which is able to operate as a 12V Motor Speed Controller, LED Dimmer, Heat controller, voltage controller for an electrolytic etcher etc.   I did some hunting around on the interweb and found a pretty good starting point in Circuits Today, but then, I needed to make […]

This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser. This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was designed with HTML […]
