This is an orbital shaker: There are some DIY ways to make an orbital shaker. One thing an orbital shaker is used for is growing biological samples. In which case control over light, and light cycles, may be important. Jakub Nedbal, Lu Gao and, Klaus Suhling have written up instructions for modifying an orbital shaker […]

DMCdrive: a $10 micro-drive system for electrophysiology & optogenetics
In the field of neuroscience, micro-drive systems are used to position electrodes in order to make electrophysiology recordings. The DMCdrive is an open-source multi-tetrode for electrophysiology that costs ~$10 per micro-drive. It includes an optical fiber for optogenetic experiments and is demonstrated on freely moving mice. The device is presented in a paper on the […]
3D Print a Stethoscope
Here at Lab On The Cheap HQ we’ve received a few requests to look into ways that people might easily and cheaply transmit audio from a stethoscope over their phone to a medical practitioner they are teleconferencing with. While we are looking into the best solutions for that problem, we’ve noticed a lot of methods […]
Hack a kitchen scale for lab use for just $20
Common digital kitchen scales have a surprisingly high sampling rate in their sensor, but any data logging using a kitchen scale is limited to the sampling rate of the scientist writing down the data. But now, there is a preprint paper on hacking a digital kitchen scale to record data to a computer by D […]
Hyperspectral Imaging for $500
Hyperspectral imaging refers to imaging in which a spectrum is acquired for each pixel in a captured image. A paper by Jairo Salazar-Vazquez and Andres Mendez-Vazquez details an easy to assemble hyperspectral device for just $500 which can take a spectrum from 400-1050 nm with a wavelength resolution of up to 2.1 nm and a […]
