Fwd: spi programmer the haxor way

[Urja Rannikko]

Okay,

just for fun an image of an emergency SPI programmer
- ATtiny2313 as an RS232-SPI bridge
- did 38400 baud serial, 4Mhz SPI
- was very slow ... 2h+ for programming a 16MBit SPI flash
- the ATtiny and the SPI chip were powered by two 1.5V D size
batteries (covered in electrical tape)
- the RS232 line lever converter was powered by the 5V regulator on board ...
