but when I do, i build them myself :D

Since I stumbled on sites.google.com/site/cartedar… I've been wanting to try and make one, and I've finally found half an hour to do so.

This includes discovering that the cartridges I still had from my school years (last millennium) were dry, refilling one of them, discovering that I don't know how to refill an ink cartridge without spilling ink (luckily just on my hands and on some paper ads that were there to protect the desktop) and finally trying the pen.

For something made out of a soft drink can, it writes pretty well.
