TWR-SB0410-36EVB: Tower System Board - SB0410, Quad Valve/Pump Controller SoC

Sub-μA current sensor based on Kinetis K22F

The Sub-μA Current Sensor is a Kinetis K22F based current measurement board running on FreeRTOS and can be used with the Freedom Development Ecosystem or any other Arduino-like development board.

This reference design allows for non-intrusive connection between any MCU and a 3.3V shield and measurement of a wide range of low currents (~60 nA – 5 mA). Multiple communication methods are available, including integration with Freedom Sensor Toolbox (CE).

posture correction robot

It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.
