If i may ask, how did you manage to make. The circuit speedkar made? I bought an eeprom programmer from ebay and and trying to figure out its setup. Can you give some details on your circuitry

It was super simple. Just follow his schematic. Iw 5.1v zener diode x3. 4.7v resistor x3 a few little wires and a pamona clip on a little prototype board. I just cut a serial cable i had. I can post a picture in a few hours. I ended up buying hundreds of resistors and diodes because there is no more Radio Shack around here.

If you can make a kit for the resistors/diodes, I can buy from you?

Send me a message with an address and I'll put some in an envelope and get them out Monday.

Last few days I have been trying to get this programmer working for the eeprom. I was able to read from an arduino but I'm not sure if its working as should.
