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.
Our 75:1 HP micro metal gearmotor is now available with an extended motor shaft that works with our recently released optical quadrature encoders. If there are other gear ratios that you would like to see available with extended motor shafts, we would love to hear about it.
When properly modified for continuous rotation, hobby RC servos become an inexpensive, compact, easy-to-use actuator system for robotics projects, and servo manufacturers are increasingly answering the growing demand for such products with servos designed specifically for robots. One example is Power HD’s new AR-3606HB continuous rotation servo, which offers open-loop speed control rather than the closed-loop position control you typically get with a servo. It is the fastest and strongest continuous rotation servo we carry (up to 71 RPM and 93 oz*in of torque), with performance well suited for driving a small robot.
These basic boards conveniently break out the VBUS, GND, D-, D+ and ID pins of USB Mini-B and Micro-B connectors to a set of five 0.1″-spaced pins, making it easy to power your project from a USB port or to add a USB connector to your breadboarded USB microcontroller. The compact USB Mini-B Connector Breakout Board measures 0.55" × 0.85", while the even smaller USB Micro-B Connector Breakout Board measures 0.44" × 0.5" (including the USB connectors).
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.
