Welcome to the Pololu Blog, where we provide updates about what we and our customers are doing and thinking about. This blog used to be Pololu president Jan Malášek’s Engage Your Brain blog; you can view just those posts here.
We have released a new machined aluminum bracket that lets you securely mount our 37D mm metal gearmotors to your project. The bracket has six holes on its face that line up with the 37D gearbox’s mounting holes, and it has three tapped holes on the bottom. Nine M3 screws are included for securing the bracket to the motor and mounting surface.
Our new QTR-3A and QTR-3RC reflectance sensor arrays pack three IR emitter and receiver (phototransistor) pairs onto a board measuring just 1.25″ × 0.3″ (32 mm × 8 mm). With the sensors mounted on a 0.375″ pitch, these sensor arrays are great for sensing 3/4″ black electrical tape when used as minimal detectors on line-following robots!
The SparkFun Starter Kit for RedBoard is an easy way to get started building entertaining and educational circuits with SparkFun’s RedBoard, an Arduino clone that is compatible with the Uno R3. The kit includes a RedBoard along with various types of sensors and indicators. A downloadable guide features example projects to introduce you to the world of embedded electronics.
We are excited to release this new video for our Maestro Servo Controllers! Get some ideas for cool things you can do with the Maestro, and see how easy it is to get started with our custom software. This is the first of many fun new Pololu videos to come! Let us know what you think or what other products you would like to see in action in the comment section below.
Lunokhod, which means “Moon Walker” in Russian, was built for a space museum in Prague and is a miniature version of the first remote-controlled moon rover. It is uses 8 of our 298:1 Micro Metal Gearmotors and an Arduino Nano and can be remotely controlled by museum visitors.

We have released three new step-up regulators that can boost input voltages as low as 0.5 V and have typical efficiencies between 70 and 90%. Unlike most boost regulators, these offer a true shutdown option that turns off power to the load. They also automatically switch to a linear down-regulation mode when the input voltage exceeds the output, making them great for powering electronics projects from 1 – 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell.
We’ve lowered the prices on all of our ball casters! Prices have dropped by $1 to $2 across the whole Pololu ball caster line and start as low as $1.99.
This “optionally piloted aircraft” is a Cessna 150 that customer Ryan Olson fitted with an autopilot and remote control system using the Pololu jrk 12v12. It is used for UAV training and development at the National Test Pilot School in Mojave, CA. Ryan’s AUVSI 2012 abstract is available online, and you can see some pictures of the internals below.
