433.92 MHz RF Remote Control. Use the BASIC Stamp or PicBasic serout commands to control the transmitter and serin for the receiver to create powerful communications links, robotics control applications, you name it -- With an operating range up to 400+ feet, these tiny RF modules make the addition of RF remote control or wireless data communications very affordable, and they are incredibly simple to use. The TWS-434 & RWS-434 TX/RX combination can be used with direct asynchronous serial data, and are an excellent choice for BASIC Stamp, PIC, 8051 applications, and home remote control systems. Build remote data-logging applications, or robot colonies that communicate via RF links..

Silver DAC / V 3.5 DAC

Smart lock (12C508A). The base sends a data sequency (the password) which is recognized by the key. The key checks the sequency and -if it recognises it -sends to the base another data sequency, as an answer to the password. At the time when the base gets a correct answer (which means that the key has been introduced), the relay is put into action, and it can command a number of consummers.
