Construction of the Mk1 Receiver

Posted on Sep 27, 2012

The remote control receiver is a custom design based on a pre-built 433MHz UHF radio receiver, a decoder chip and a BASIC Stamp. The Stamp is expensive, but easy to work with. The receiver requires 8.5mA, plus 1.5mA for each LED (individual or segment) that is lit for a maximum of up to 23mA. In practice it is between 13 and 16mA. Pressing a button on the remote transmitter causes the receiver to consume an extra 0.2mA. In the `power saving` mode the PBASIC `nap` instruction is used in combination with turning all the LEDs off to reduce power consumption to 4mA. The battery should last about 30 hours of on-time.
