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.
With the release of the new RC Switch with Digital Output and the new RC Switch with Small Low-Side MOSFET, our RC switch family overhaul is now complete. These compact modules convert hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. These products replace item #752 and item #1210, which have been put on clearance and will be discontinued when the remaining stock is gone.
For more information about these products and the rest of our RC switch family, see our RC Switch category.
The overhaul of our RC switch and RC multiplexer products continues with the new Pololu 4-Channel RC Servo Multiplexer. This compact four-channel multiplexer of hobby radio control pulses allows for easy switching between two independent RC signal sources. An auxiliary channel selects whether master or slave inputs show up on the four output channels. This makes it ideal for applications in which you have two possible control sources and want to be able to switch between them on the fly.
For more information about the new Pololu 4-Channel RC Servo Multiplexer, see the product page.
Halloween’s always a good time at Pololu. Here’s a shot of all the people here that dressed up for the holiday:
I (Emily) used some of our LED strips to make a Luxor Hotel costume. (For those of you that don’t know, Pololu is located in Las Vegas, NV, not too far from this building.) You can see a video of this costume in action here.
If you used any Pololu products in your Halloween costume or decorations, we’d love to hear about it! Please post about it on our forum and maybe we will feature it here on the blog. Have a Happy Halloween!
Pololu forum user Martan recently released a project called Wireless Servo Widget. The project website says:
The Wireless Servo Widget is based on our Wixel Programmable USB Wireless Module. Martan wrote apps for the Wixel that use the packet addressing feature of the CC2511F32 chip to implement a round-robin protocol. He also made a Slave Widget Breakout Board which makes it easy to plug servos into the slave Wixels. All of this and more can be found on the Wireless Servo Widget website.

If you said “yes” to any of these questions, you might just be interested in our 2013 Pololu T-Shirt!
Some of our favorite examples of when/where to wear this T-shirt:
You can find these and last year’s shirts in our shirts category.
Halloween is just around the corner, and people are looking to make fun costumes. I recently took a couple of calls from customers who were looking to make Katy Perry-inspired costume dresses with spinning peppermints, following the instructions found on this RPF forum thread. Parts from Pololu used to make the dress included an enclosed 3-AA battery holder with a switch and a Solarbotics GM3 224:1 Gear Motor. However, we suggest substituting our 200:1 Plastic Gearmotor, which has similar performance but no back shaft that needs to be removed.
If you have a cool costume that uses our products, please feel free to share them in the “Share your projects” section of our Forum.

Geoff from Tabletop Robotics wrote a tutorial on how to build a Flipbot, a basic differential-drive robot that can keep on going even when flipped upside-down. A Wixel serves as the brains of the robot, and a second Wixel in the remote allows the Flipbot to be wirelessly controlled. In addition to the Wixels, the Flipbot uses a number of Pololu products, including:
The accelerometer is used to determine when the robot is upside-down. Geoff’s tutorial has a full parts list and a diagram of how everything is connected; the complete source code is also available.
