Merchants and manufacturers

The following page is just a listing of some merchants and manufacturers that I or people I’m doing projects with commonly use or recommend. This is no exhaustive list - I mainly keep them for my own reference.

Note that these sellers are usually selected to ship in Europe / Austria and are only listed here when they also ship to private individuals and not only to companies or educational institutions.
