- 2003-02-07 - 0.5mm / 0.8mm Breadboard - Posted by: Jeff Frohwein
- CREDIT CARDS now accepted. Part #5800 is a 0.62 inch thick dual-purpose PC board for adapting most 80-pin, or smaller, QFP or TSOP devices to 0.1 inch header spacing for easy breadboarding. One side supports 0.5mm spacing parts and the other side supports 0.8mm spacing parts. Soldering headers to the appropriate side determines which side to use. Because of the unique design of the board, any device 80 pins or less, can easily be supported. QFP parts will work regardless if each side has an odd or even number of pins.

- 2001-01-24 - Frohwein-Sshua Flash Programmer - Posted by: Jeff Frohwein
- This version of the flash programmer by Sshua is optimized for 29F040 (and similar) flash chips. On one computer, it took more than 15 minutes to write 512Kb to a 29F040. Replacing the 74HC590 (binary counters) by 74HC595 (shift registers) on the address bus reduced this to 3 minutes. It's now a little slower than before for other eeproms.
