Last year at around this time we covered Paperfuge, a card stock based centrifuge that could spin QBC capillary tubes samples at ~10,000 g. Using the principles laid out with Paperfuge, Gaurav Byagathvalli, Aaron Pomerantz, Soham Sinha, Janet Standeven, and M. Saad Bhamla have come up with 3D-Fuge detailed in a paper on the bioarxiv […]

OMIS: An Open Millifluidic Inquiry System
OMIS is a 3D tool for performing small-scale chemical synthesis and analysis. The system is Arduino-based and consists of an automated syringe pump run by a cheap stepper motor and reaction vessels. The design is meant to allow for fabrication” in one day”, and can pump fluids at rates between 60 and 300 μL/min. The paper, […]
Nyx Tracker for widefield Astrophotography
LabOnTheCheap posts tend to be microscopy heavy, but what about microscopy’s extroverted cousin, telescope photometry? One issue while taking long exposures of celestial objects is tracking their diurnal motion in the sky as the earth rotates. Robust tracking mechanisms start at around ~$300 and quickly go up in price for more accuracy and heavier telescopes. […]
A 3D Printed Platform Jack
Lab Jacks, or Scissor Jacks, are not particularly expensive bits of equipment to begin with. As long as you don’t go through VWR, a good 4×4 inch lab jack will cost you $30, and an 8×8 inch lab jack will cost about twice that. If you want to 3D Print your own lab jack. Thingiverse […]
OpenDrop
OpenDrop, now in its third version, is an open source digital microfludics platform based off electrowetting technologies, that can confine and move droplets of liquid. The device is made by GaudiLabs, the source of Generic Lab Equipment. The platforms best first impression is probably this software demonstration video: OpenDrop is open source, which means a github […]
