I got all inspired by Stan Swan's "433MHz + Picaxe = Magic" article in the Jan 2006 Silicon Chip, and dashed out to my local Jaycar to buy a Tx/Rx pair.
In about 15 mins after arriving home I was transmitting data from my 08M-based temperature logger to my PC. It was almost embarrassingly easy!
Just a question on the supply voltage for the Tx. The datasheet from Jaycar specifies max 3V supply for the Tx, and 4.5 - 5.5 Volts for the Rx. Stan's article has them both running from 4.5 - 5.5 Volts.
I've been running my Tx from a 78L05 fed by a 9Volt battery with no ill effects, so far. Admittedly, it's only been for in bouts of about 10 mins continuous running.
I only noticed the 3V requirement after seeing some other 433MHz pairs on the net saying 3 - 12V supply and went looking for the data at Jaycar. (I'd done my initial setup straight from Stan's article - noticed your errata, Stan, when I went to get the Basic scripts.)
Has anyone else been running from 5 Volts? Any problems?
