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 […]
Make a polarimeter for $350
A polarimeter is used to characterize a sample by measuring the rotation of polarized light when it interacts with the sample. They can cost upwards of ~$10,000, but a $350 DIY high-resolution polarimeter has recently been detailed in a paper by Andrew Harvie , Tom Phillips, and John deMello. The bill of materials for the […]
