New products: Fixed 3.3V and 5V Step-up Voltage Regulators U1V10F3 and U1V10F5

New products: Fixed 3.3V and 5V Step-up Voltage Regulators U1V10F3 and U1V10F5

We have released two new step-up regulators that can boost input voltages as low as 0.5 V. Like the very similar U1V11x line of step-up regulators, these modules automatically switch to a linear down-regulator mode when the input voltage exceeds the output, making them great for powering electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell. These modules do not offer the U1V11x shutdown functionality, which allows them to be much smaller (just 0.35″×0.45″) and a little less expensive ($4.49 each).

These regulators are available with a 3.3 V or 5 V fixed output voltage. For other options, you can take a look at our full selection of step-up voltage regulators, step-down voltage regulators, and step-up/step-down regulators.

New products: Encoder motors for 25D mm and 37D mm metal gearmotors, without gearboxes

We are now selling the motor and encoder portion of three of our metal gearmotors, without a gearbox. The pinion gear on the output shaft works with the gearboxes on the corresponding products, so these can be used as replacement motors or encoders.

ARM mbed NXP LPC1768 price reduced by $10

You can now buy the ARM mbed NXP LPC1768 Development Board for just $49, a reduction of $10. We also lowered the price of the m3pi Robot + mbed NXP LPC1768 Development Board Combo by $10, to $189.95.

From the product page:

The mbed NXP LPC1768 is an easy-to-use MCU development board designed for rapid prototyping. At its heart is a powerful 32-bit ARM Cortex-M3 processor running at 96 MHz with 512 KB flash and 32 KB RAM, which makes it far more capable than popular 8-bit prototyping alternatives. A comprehensive firmware library and plenty of sample code help you get your program up and running quickly, and a free online IDE and C++ compiler means that no software installation is required. Downloading programs is as simple as using a USB flash drive (no external programmer is necessary).

RGB shoji lamp

This Japanese-style lamp by Pololu engineer Kevin Chang was made from laser-cut parts and uses an RGB LED Satellite Module 001, a ShiftBar, and a Pololu Mini Maestro 12-channel servo controller.

Here is a video of the lamp in action:

Freedom Zumo Robot

This robot uses our Zumo robot kit, 75:1 micro metal gearmotors, and a Zumo reflectance sensor array. Instead of an Arduino it uses a Freescale FRDM-KL25Z as the microcontroller board. Sample code is available for line following and maze solving.

DIY fully-automatic book scanner

Posted by Ben on 13 February 2012

This do-it-yourself fully-automatic book scanner uses a Maestro servo controller to control the page-turning, and picture-taking servos. It was able to scan 468-page book in about 12 minutes with zero page-turning errors. For more information, see the DIY Book Scanner forum thread.

Controlling the Pololu 3pi Robot using a Joystick

Posted by Ben on 3 February 2012

This project by Pololu forum user Wilfredo shows how to control a 3pi robot by directly connecting two joystick outputs to two of its analog inputs. Here is a schematic of his setup:
