* Collecting OLD, classic 8/16 bits computers.
I already have ZX-Spectrum, ZX-Spectrum+, ZX-Spectrum+2, Commodore VIC20, Commodore 16, Commodore 64, Commodore 64G, Commodore 128, Amiga 500, Amiga 1200, Scheider CPC 128, Enterprise 128, Laser, Videoton TVC, Primo A32 computers

I have developed a complete PRIMO emulator. This machine was a Hungarian 8bits computer in the 80's.
The emulator homepage is here , but that's completely Hungarian at the moment.

* Planning/building electronic circuits
I'll upload some images soon...
Was working with my schematics when I realized, that the old ways are not good enough anymore. There are too many gates and wires, the schemas are getting too complicated and building the testboard is a pain in the ass.
I looked around and have found today's most interesting solution: the FPGA. Man, this is the circuit, I've been waiting for. Planning the internal structure as a program file, then syntheze it, and you'll get what you want within one fat chip. And it is fast. Really fast. Xilinx seemed a good choice as they are market leaders, so I have happen bought two developer boards, one with the Xilinx Spartan II chips (100K gates), and thanks to 'Kinai' (a friend of mine, living in California, USA) I've got a Spartan III board (400K gates). A new world has opened. Just learning the VHDL, but I see already, this new method extends the possibilies of electornic design. I will put some examples and sample projects here as long as I will able to do so... :)

FPGA's rock, man!

This hobby is really just a tribute to this toy, I truly beleive that LEGO is an excellen buling toy. Unfortunately nowadays the sets are not as great as they were in the 70s'-80's.
I do love the classis space theme, so I collect the sets. It is an expensive hobby, though.

A place you have to see if you're intereted in old legos: LUGNET
