cardkicker

i find it hard to understand why you would want to use a nand gate for this?B/C a nand gate is like an or gate,,, if A&B is low then = 1 if A&B is High then = 0 if A or B is high then = 1 the or part just ruins it for this decoder i think. butt if you have a chip or something you are studying i wouldent ming helping you do a little research.

i do olot of searching and dont find much. Sense this circuit was so hard for me to find i want others to see it.

sorry bought that butt i found the info for ya.If you want to take a look at the site i got that photo off of it has plenty to offer.Far as the mathametics go theres enough math there to hurt my head so her ya go http://www.aaroncake.net/circuits/index.asp knock your self out ;D

maybee this will help...

I cant help very much on the nand part butt i do have an example that might help you.

There is a number of ways to use the card,Try searching for pony prog, card pro, Extreme hu for Dtv, winex, identifile, ic prog,they are all free and i left a lot of them out cause i cant remember them all, Butt card pro and pony prog has options for connecting fun card programmers,i would like to see your schmatics on the fun card programmer you built if you have them handy, i am also working on an project, if you just want to experment with sending and recieving data the search for windmill, it's a free program to help with troubleshooting,,, ;D CardPro.zip
