Simple DC brushed motor driver using TI’s DRV8837 1.8 A PWM-controlled H-Bridges. Board is designed to be mounted onto a Teensy 3.X although it can also be used on a breadboard. The H-bridges allow the motors to be driven both forward and reverse, with braking and coasting options as well. SLEEP pin HIGH enables the motors.

Simple circuit using LCM555 timer for clock to operate SN54LV163A binary 1 - 7 counter which drives FFB3904 dual mosfets that control two rgb LEDs which, lastly, cause the owl’s eyes to glow with continuously varying color. Intended as a wearable pendant for little girls and daring men. Runs off of a 40 mAH LiPo. Added SMD switch for power on/off.

Simple Teensy 3.1 add-on board to test the relative performance of various state-of-the-art MEMS pressure sensors. Included is Invensense’s 3.5 mm x 3.5 mm ICM20730 7-axis motion sensor with accel/gyro and embedded pressure sensor, Bosch’s 2.5 mm x 2 mm BMP280, ST Microelectronics' 2.5 mm x 2.5 mm LPS25H, and Measurement Specialties' 3 mm x 3 mm MS5637. Broken out are all interrupts (ICM20730 and LPS25H) and all I2C device address bits (ICM20730, BMP280, and LPS25H) to avoid address conflicts. Also broken out is the ICM20730 FSYNC pin to test electronic image stabilization. Added bypass caps on ICM20730 VDD and VDDIO.
