Open Source Projects
Explore open source hardware projects other folks uploaded and share your own. With CADLAB.io hardware version control it is way easier to work on hardware design projects together.
8-channel microphone array cape for the beaglebone black.
This repo contains one-sided eagle files that can be used to build an LED Driver circuit for a car. The idea is to first low-pass the signal coming from the head unit, with a simple capacitor and resistor circuit. I found that I sometime wanted to adjust my crossover frequency, so I have used a potentiometer in the place of the low-pass resistor.
After filtering, the signal is amplified 100x and used to drive a MOSFET which acts as a switch to turn off and on the LED's. Video of this working can be found here (link coming soon).
I have only included the schematic and the board files.
PC cooling controller for rotary cooling devices (fans/pumps). It has the following features:
Supports 4 cooling devices.
Can disable devices that still run on minimal PWM.
Monitors devices RPM.
RPM measurement supports pulse stretching.
Supports 2 thermal sensors.
Error signal output.
Can be controlled/queried over RS-232 interface.
Command-line client to query/debug/control the device.
Hardware design and source code is MIT-licensed.
A smallish and spartan music player that can work for weeks between charges, able to decode ogg vorbis, mp3 files
an audio amplifier project that contains a mixer controlled by an MSP430 microcontroller
gps tracker based on a MSP430F5510 uC with a gprs connection for reporting and command input.
