Here’s a nifty idea published in PLOS by George Korir and Manu Prakash. 15 on-chip pumps controlled by a punch card cranked by hand. While the original design is specifically geared towards ease of distribution, one could replace the hand crank with a cheap stepper motor for more reliable control.
We’ve covered making your own syringe pumps before, but we’d like to draw your attention to this amazing write up by DropletKitchen to make push-only syringe pumps. Since this is the second post from DropletKitchen, consider perusing their various projects.
An anonymous reader emailed us to share a small DIY microfluidic rig equipped with inexpensive board cameras. The chassis is mainly made out of laser-cut acrylic sheets, M6 nuts, and bolts. This GitHub page gives a comprehensive list of components complete with their cost, and instructions on how to assemble them.
While we love the syringe pumps from SyringePump.com (really!), consider making your own syringe pumps instead with the Open Source Syringe Pump Library. If you want the with it, here’s a more professional looking arduino-based setup.
While more expensive than a razor blade, you can cut Parafilm or tape to make precise chambers and masks without a laser cutter by using a commercial knife printer like the Silhouette CAMEO. From our own experience its remarkably robust though it can be a little finicky when loading the cutting mat before that actual […]
