I had a TV integrated remote receiver IC from Radio Shack which detected a Roomba Virtual Wall and also a keychain TV remote, so how can the frequency be different? I think it is specified for the 38khz standard. In the Neato Optical Boundary thread and related included links. There are a few different standards in use, seemed to match here.

Can someone please provide me a list of everything I need in order to create this virtual wall


From noob to fellow noob, have you read this entire thread? Some folks don't respond to the "I'm a baby bird please feed me" posts. You will get a lot more respect once they see you have done your homework. Please don't take offense to this, as I am merely trying to help. If you haven't take the time and read this entire post. Happy Hacking.

Guide to introductory electronics and microcontroller material was supplied privately not to clutter or duplicate web tutorials. There are both Arduino as well as PIC virtual wall replacements. PIC's require commercial programming hardware and software tools, but allow more compact specialized projects. Arduino's offer simplified programming tools for beginners, free software. Request the PM's privately if wanted.

PIC Microcontroller resources
Various size controllers, smallest only $1. Programming boards to flash under $10.

Free PC development software e.g.

Arduino has various ready made application attachment boards, sensors etc., "shields", while the PIC is more compact for custom made applications, with separate flashing "programmer" boards to install programs in the controller, moved to a DIP socket on the project board.

Can someone post the schematic image please? The original ones aren't accessible any more.

Thanks!
