Several gear ratios of our medium-power (MP) micro metal gearmotors are now available with extended motor shafts:
- 10:1 MP micro metal gearmotor with extended motor shaft – 2200 RPM (no-load) and 3 oz-in torque (stall) at 6 V
- 75:1 MP micro metal gearmotor with extended motor shaft – 290 RPM (no-load) and 17 oz-in torque (stall) at 6 V
- 100:1 MP micro metal gearmotor with extended motor shaft – 220 RPM (no-load) and 19 oz-in torque (stall) at 6 V
The extended motor shaft rotates at the same speed as the input to the gearbox and offers a way to add an encoder, such as our new magnetic encoder for micro metal gearmotors (pictured below), to provide motor speed or position feedback.
Last month, we introduced our new carriers with Sharp GP2Y0A60SZLF analog distance sensors, a part we are very excited about and have been trying to get for the past five years. Those complete sensor modules ship with the GP2Y0A60SZLF installed on our compact carrier board, which includes all of the required external components and provides a more convenient interface to the sensor (and a mounting hole!). Well, we are now offering the carrier boards without the sensor for those who already have Sharp GP2Y0A60SZLF units and are looking for an easy way to incorporate them into their projects. The carrier boards are available in two configurations: a 5V version for operation from 2.7 V to 5.5 V and a 3V version for operation from 2.7 V to 3.6 V:

Sharp’s optical rangefinders and distance sensors have long been a favorite among robot builders for quick, easy, and affordable obstacle detection. We are excited to add to our selection the new digital GP2Y0D815Z0F sensor, which can detect objects ranging from 15 cm (6″) to almost touching the sensor face. The GP2Y0D805 and GP2Y0D810 digital sensors we have had for years are great because of their small size, high sampling rate, and small minimum sensing distances, but their short detection ranges have limited their applications. We have always wanted a version that could see farther, and now we have one! We have the sensor available by itself and on a carrier that makes connecting and mounting it a lot more convenient.
Last weekend, Pololu engineers Brian, Jeremy, Kevin, and Ryan participated in the AT&T Car and Home Hackathon. They competed against around 300 people who came to The Cosmopolitan hotel in Las Vegas to participate in the event. The sponsors provided hardware, development boards, supplies, and APIs for the teams to work with, and they had 26 hours from Saturday to Sunday to make a home automation or “connected car” project.
Team Car Bon, which also included local programmer Dylan Simpson of the Las Vegas Ruby Group, hacked together a carbon monoxide sensor that would be installed in a car or garage and connected to the internet. The idea was for their system to monitor carbon monoxide levels, and if the levels became dangerous, to shut off the car engine, open the garage door, and alert your phone.
Our engineers also took first place (in one of many categories) at another AT&T hackathon earlier this year, which sets a high bar for future Pololu participants. Come out here to compete in the next AT&T hackathon and help put the pressure on our next team!
A few of us are at work late having our Palm Tree League fantasy football draft after a week of qualifying events to determine draft order, including guessing how long it would take to print a 5cm-tall Yodapus Rex with a 3D printer we assembled recently. (Answer: 5.25 hours.) By far the most entertaining event was the race we ran yesterday around the outside of the Pololu building. The race was a little over 300 meters long, and many people from Pololu participated. Congratulations to Jon for winning for the second year in a row (although much of the margin he beat me by was from his false start). And Candice might want me to point out that she is pregnant so she has a decent excuse for finishing last.

In the United States, the first Monday of September is Labor Day, a holiday celebrating the contributions of workers. As a robotics company, we appreciate all the physical and creative work that goes into the creation of “labor-saving” devices, and we hope you will join us in celebrating these efforts, perhaps by spending the long weekend working on your own robotic creations.
We are having a big Labor Day sale throughout the weekend, with 15% discounts on over 400 products when you use the coupon code LABORDAY14. Note that we will be closed on Monday, so orders placed after 2 PM Pacific Time on Friday, August 29 will be shipped on Tuesday, September 2.
