Facelesstech published a new build: So some time last year I ordered one of those servo 2 axes (pan and tilt torret) arm kits from aliexpress. It was fun to play with but I didn’t quite find a reason to use it in a project. Then I seen this project on hackaday and a light bulb went off […]

Modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing, Part 1: Investigation and continuous rotation
Keith wrote an article on modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing: On its own, the servo takes power, ground, and a position input and moves the shaft within a range of rotation to match the angle requested on its input wire. It has one or more stops in its gearbox to […]
Optically controlled servo motor
Dilshan Jayakody writes: This is demonstration project to control servo motor movement using physical marker and normal video camera. In this project video camera capture the movements of marker and calculate rotation angle based on that. This calculated rotation angle is feed to the servo through small MCU based interfacing unit. In this project video […]
Wireless servo controller II
Ondřej Karas of DoItWireless writes: We described simple method, how to drive modellers servo. Today, we are going to try to drive this servo from potentiometer connected to TR module ADC. It is reaction to forum thread where is discussion about airplane model control possibility. Check out the video after the break.
Joystick controlled pan tilt kit
Bajdi writes: One of the things I bought is a small plastic pan tilt kit. I got it on Ebay. It didn’t come with the servos. But I still had some small Micro 9G servos that fit the kit. To try it out I hooked up the little servos to one of my Bajduinos. I […]
Resistor cutting robot from .:Oomlout:.
On our Shenzhen trip we were joined by the Oomlout team. While discussing a reel-to-strip cutting robot, Aaron mentioned that he has a resistor cutting robot. It’s built from laser cut MDF and acrylic, with a bunch of servos attached to load and cut the resistor tape. The project is open source, so all the […]
Tutorial on modifying servos for continuous operation
How to modify standard servos for continuous operation. This hack involves opening up the servo, removing the limit mechanics, and modifying the feedback pot. In his second tutorial Andrey shows how to add a rotatory encoder to the servo, for position feedback. It will stand still with control pulse of around 1,5ms (mine likes 1515us; […]
Launchpad based servo walker
Vinu designed and built this servo walker based on the MSP430 Launchpad. He documented his design, along with instructions on how to build one. Hi, I bought two small servo motors last month. I was thinking what I can do with this two servo, since it is only two in number. Then I asked this […]
Low-tech Arduino based cell phone trigger
William Finucane of revoltlab.com posted this article describing a simple low-cost means of activating devices remotely via telephone. I wanted to be able to call my house and turn on the lights and television during nights when I was away on vacation. What’s more, I didn’t want to spend any money on cell phone bills […]
Using servos with PIC16F microcontrollers
Raj wrote a tutorial on how-to implement servo control on PIC16F microcontrollers. The article starts off with some servo theory, and is followed with an open source practical example. A servo motor is a special geared DC motor equipped with an electronic circuit for controlling the direction of rotation, as well as the position, of […]
Autonomous servo switcher
Simon has created an servo switcher for use on autonomous vehicles. designed to allow manual control if the autonomous controller fails. Using a pic12f683 and 4066 analog switch. source code and board files are available on his website. Via Hack a Day
OpenServo project
The OpenServo Project is an open community project with the goal of creating a low-cost servo for robotics. Check out their step by step instructions, which include using the familiar Atmega168 in the servo controller board. Via Hack a Day.
Arduino/Processing based sonar
LuckyLarry has developed a sonar system based on the Arduino and an SRF-05 ultrasonic range finder. A servo sweeps the range finder across the target field, with the pingbacks processed and displayed on the desktop with Processing. Via Hackolog.
