Quick overview of things I remember being worked on:
Few people are working on mini/cheap gel boxes and PCR devices
A water purifier and a vacuum pump that both need tubing?
A mini centrifuge with some safety removed needs a minor attachment to be easily operable
Adding streaming abilities to a microscope (has an Olympus SLR mount on it IIRC, possibly to either jerry-rig or 3d print something to put a smart phone)
In the vein of 3d printing

General inventory
And the autoclave condenser tank
Help, interest, expertise, parts, other ideas are all welcome.
