It's off the thread topic but I would like to use this opportunity to ask for to make it mandatory to write some information about the location. It is ridiciuluos to come accross a rather bad post, maybe even bad english, and then don't even have a clue about location.Welcome to AAC!

You will note older member have their location posted in the upper right hand corner. This adds us in helping, as different parts of the world have access to different parts. You can update this in your profile.
AAC will allow local attachments, hosts its own albums, and will even allow you to set up your own blogs. If you need to post a schematic (and if asking an electronics question please do) please use the local resources of AAC instead of photobucket or related sites.
Schematics and pictures are worth a thousand words. It is worth learning how to post drawing or images here when asking a question.

Thanks.
The Hex inverter is a NOT gate, just has a different name. The NOR and NAND can be made to work as a NOT gate and do more interesting stuff. You will quickly outgrow a NOT gate but you can literally build an entire computer just using NAND or NOR gates....I want a NOT gate. Unfortunatly it is not listed in this list, found in another's post:
4001 NOR gates
4011 NAND gates
4071 OR gates
4081 AND gates
4069 Hex inverters
Could someone help me buy one or would it be best if I just made up my own gate by drawing some circuits, and buying transistors?
