Hi everyone,
I like making simple machines (as many here know) and i allays had the problem with writing data to EEPROMS, maybe its poor quality switches or some weird messed up circuit. So basically i wanted to make an mk14 like machine that could program an EEPROM easily and show me the contents of memory.
Before i used DIP switches directly connected to the inputs of the memory chip, i could not view data and had to enter data in binary. What hell it brought, until.....chuck norris gave birth to the PIC
Here you can see (below) the machine in action (a little messy i know but i have ordered a low insertion socket for the memory chips). It has four function buttons, View memory, Set address, Set data, increment address and enter data. When in one of the four modes the first function key becomes the enter key. Data is still entered in binary BUT displayed in hex which is really nice.

Any questions?
Want the source code? Want me to make you the circuit (which the answer is no ;D )?
