Hey, I am wondering is it hard to make the EEPROM readers and do they really work? How much do you think it will cost me to make one.

Reuse old parts to reduce cost. I used parts from an old IDE cable and serial cable. Anyway I didn't own a soldering iron and the breadboard was cheaper than a soldering iron in my local hardware shop (and my soldering skills suck anyway).

Yes they really work, but a lot depends on the PC's serial port that you are using. obcd will be able to explain it better. Something to do with the voltage levels of the RS232 port: mark and space thing if I understood him right.

Hmm what all did u use? I have a solder iron gun soo thats not the problem. I have a IDE cable i can use also. And i also have some old pc parts i can use biggrin.gif  But idk wat i need and dont need sad.gif

You need 2 resistors, 2 zener diodes, and a DB-9 female connector. I presume you already saw unicron's diagrams. The old serial cable was to recycle the DB-9 connector. The IDE cable was to recycle the wiring. If you want to cut down on the cost of the PCB/breadboard, you could solder the correct parts and short them together assuming you are good with the soldering iron like what this guy did:  http://mail.exis.net...kus/item_77.htm.

I'm bad with the iron so I had to use the breadboard as an easy way to connect the parts together. A multimeter is useful to have to check continuity. btw zener direction (orientation of the dark strip) matters.

Yes i am good at soldering i think..So i need to buy those 3 things you listed. Quote"2 resistors, 2 zener diodes, and a DB-9 female connector."

But i dont get how everything is wired up using the mint can. Is there a digram anywhere?
