STEP 1 : Make sure you have the proper tools

The components of the PlanktoScope are available from many vendors, online and otherwise. You will need a few tools, but the construction is straightforward and should take a few hours to complete. We have detailed guides on the website for both hardware and software assembly. The PlanktoScope community is also here to help in any way we can.

Soldering station with flux, or flux core solder, will be used to make a few electrical connections

Any tap wrench compatible with the M12x0.5 tap will work

A M12x0.5tap will be used to secure the objective and tube lenses

A screwdriver kit with multiple drivers will make many of the operations straightforward

Here is a suggestion of links to order the appropriate tools :

STEP 3 : Machine your structure

In order to complete your kit, you'll need to obtain the structure of the PlanktoScope. This structure can be machine from a sheet thanks to laser cutting or CNC machining. The structure can be machine locally around you in a FabLab or via a company able to realize laser cutting or CNC machining. The price will depend on the material you'd like to use and if you need a machine via a company or not.
