Raspberry Pi 433MHz/315MHz Removing Signal Noise For Better Reception

Recently I changed from using a PP3 battery for powering 433MHz transmitter/receiver modules being used with a Raspberry Pi. To powering them from the same supply as the Raspberry Pi. The noise from the Raspberry Pi on the power supply prevented any meaningful communication. I found the solution was...

Re: Raspberry Pi PiCycle Exercise Bike Trainer, Open Source Python

It should be possible to do that. All of the computer cycles and the player cycle where instances of the same object, and held in the same array of cycle objects. The current player object is just taken as object 0 and treated as a human player. In theory object 1 could also be made the special case...
