New products: Step-up Voltage Regulators U1V11F3, U1V11F5, and U1V11A

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.

These regulators are available with a 3.3 V or 5 V fixed output voltage or an adjustable output voltage (2 V – 5.25 V).

Flight Testing of a Surrogate UAV at the National Test Pilot School

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.

Digital Capabilities: a digital garden

This digital garden by the University of Lincoln uses a Raspberry Pi, 20 jrks, and linear actuators to move panels, revealing the plants behind them, in response to tweets. More information is available on the project’s website. The project was awarded a gold medal at London’s Chelsea Flower Show.
