I thought this pre-print might be of interest to the group here. For those not familiar with Manu's lab - he heads up the Foldscope project (https://www.foldscope.com/) but does a ton of great work making highly functional, low cost microscopy solutions. Squid is a great example of a flexible microscopy platform that can be built at the fraction of the cost of a microscope from one of the big 4.
Wanna build one? Instructions are here: https://squid-imaging.org/
