Hack your servo for 10 bit precision
Hobby servos are great for quick jobs, but if you attempt to do very precise work with them, their limited resolution quickly becomes an issue.

Lift heavy things with a modded servo
Need to do some heavy lifting of the physical kind, but only have some wimpy servo motors on hand? Why not follow Antonb’s directions to Hack your Servo, and turn it into a powerful linear accelerator.

TwitchFinger robot build notes
I’m converting a Twitchie kit into a finger-controlled robot arm. I built a little servo breakout on some perfboard, and added pin headers to plug a flex sensor into it, making a voltage divider circuit for the Arduino. This means the angle of the servos changes (rapidly!) as you bend the sensor. I’ll be attaching […]

Here’s an idea for a basic, but useful, Arduino project for the relative beginner. It uses an Arduino, an Ethernet Shield, and a Latronix Xport Direct to control a servo-mounted webcam over the net. Arduino Webcam Servo Project

Another coat hanger walker
Here’s a one-motor coat hanger walker I spotted on Flickr. It uses the same single-motor hacked servo and BEAM bicore circuit as the Jerome Demer’s project I featured in my book, Absolute Beginner’s Guide to Building Robots, but the leg configuration is different than Jerome’s and my bots, and the center of gravity is shifted […]

Todbot makes an interesting suggestion Analog meters are hard to use in hardened environments. If you’re showing data from digital sources, why not use a digitally-controlled analog meter? laser cut acrylic meter face & needle, tiny 25mmx12mm $3 servo, and arduino. – Servos as meters on Flickr MotorShield for Arduino Kit

I featured Jerome Demer’s ingenious little one-motor walker in my book Absolute Beginner’s Guide to Building Robots. I’ve been hoping he’d put up an Instructable and he finally has. This is a bit of a finicky mechanical build, but worth the effort. It uses a standard BEAM bicore circuit as its brain (via the 74HCT240 […]
