I've been cooking and reading literature relating to cooking a lot more recently. Mostly stuff like Apicius' de re Coquinaria. Aside from that, I've been working on 3D Printing a working RC Focke-Wulf Ta-152.
Other hobbies are Carpentry (Built my own desk from the ground up), Airsoft, Playing guitar/bass, Electronics (rPi/Arduino), Programming (68k assembly, C, C++, C#), Gamedesign and -development, Tinkering with my old Amiga 500 and hopefully soon I'll get around to building a forge and acquiring an anvil in the hopes of making some plate armor.
I really don't have enough time to do everything and it frequently annoys me.
