A Nixie Clock in A

The incredibly compact IN-14 based nixie clock in a Marine Band harmonica case. It shares the same code as my previous clock, Satashnik. The circuit is mostly the same, except that it's changed for IN-14's and made to fit in the tight space of harmonica case.
Harmoshnik, Nixie Clock in A

Eagle stuff is here.
Source code: Harmoshnik updates follow the Satashnik tag. This time I've had a chip that needed some serious calibration for its RC oscillator, the code update is mostly about that.

What's cooking...

New, multiplexed design with only one ИД1 and unique tunnel-vision ИН-2's.

Satashnik (IN-2, Muxed)

And BTW, IN-2 footprint was updated in the library. If you started a design already, update before it's too late.

[M]ouse connects a PS/2 mouse to Commodore 64

[M]ouse: PS/2 to C64 adapter

This adapter lets you plug a PS/2 mouse in a C64 and use it with mousing graphics editors or GEOS. It emulates both propoprtional (analog) and joystick modes of Commodore 1351 mouse. Full schematic and source code available.

Hacking with Style: TrueType VT220 Font

I spent some time looking around the net to find a font that mimics DEC VT220 terminal glyph appearance. There is none. There are some old bitmapped fonts from X11 and probably early MacOS distributions that claim to be DEC fonts, they are functional but their visual quality is lacking and nostalgic value is absent. What I wanted is a font that fills my virtual terminal window with the magic hacking glow...

Цветной композитный PAL-выход для Altera DE1

Накладки во время cc'09 сподвигли меня на реализацию кодера композитного видеосигнала для vector06cc. Небольшая заметка о том, как это было сделано. Без особых подробностей, скорее не руководство, а чтобы самому не забыть. Но вдруг кому пригодится:
ПАЛ-кодер на Altera DE1

Problems with nonstandard VGA output on my Vector-06C FPGA replica made me implement composite PAL output. DE1 board has enough resources to throw in full-colour PAL signal without any additional components. R,G,B wires of VGA output are connected together to cope with 75 ohm load, the rest is done in verilog. This short writeup is Russian-only because there seems to be enough PAL-related info readily available in English. All source code is available in the main vector06cc source tree.
