BioAmp is a biopotential acquisition device (EEG, ECG, EMG, EOG, etc.) developed in the Prototyping Laboratory at the School of Engineering of the National University of Entre Rios (Argentina). Main features:

Blinkenschild is a portable sign consisting of 960 RGB LEDs. The images/movies to be displayed are stored in a SD card in a Teensy3 board and controlled via bluetooth. Resolution is not as high as LCD monitors but the refresh rate is much higher:

BPM Biosignal is a two stage amplifier created mainly for educational purposes. Check their YouTube Channel.

BrainMap expands the accessible DIY projects for brain activity measurements. This is the conclusion project of Patrick Dear and Mark Bunney Jr. at Cornell university where they used infrared leds to measure differences in blood flow at the scalp and map the motor cortex.

Katharina and Alex are developing a classic PCR machine: 16 samples and a heated lid. You can find more details of their project here Here is a demo video:

DremelFuge is a very simple and clever centrifuge, buit perhaps not the safest one (be careful if you end up using it!). It takes advantage of 3d printing technology to print an adaptor that goes on to a Dremel (a precision tool that has really high rotation rates).

OpenBCI is a complete open source EEG system that can be built either on top of an Arduino (8-bit system), or on top of chipKIT (32-bit system), which gives the system more local memory and allows for faster speeds.

The openEEG project aims at describing and putting manuals for building a two channel EEG system for about U$200. More on instructions on how to build one, can be found here.

World Wide Series Seminar Open Ephys is a great initiative to create a suite that encompasses hardware for LFP and spiking recording, optogenetics combined with custom written software for microstimulation, environmental stimuli, extracellular recording and optogen.

OpenHardwareExG: is a project that provides both open source hardware and software for the measurement and analysis of different types of biosignals From the project page: About the OpenHardwareExG project Project goals The main goal of the project is to build a device that allows the creation of electrophysiologic signal processing applications.
