Re: Controlling a mains power socket switch? (home automation)

<t>I used the Arduino and a 433mhz transmitter in the end and for the IR used a high intensity IR LED on the end of a 10m length of cat5! also put a 1-wire temp sensor on the same cable for living room temp.  Essentially wrote a number of c++ programs that send serial commands over the Arduino FTDI ...

Re: Controlling a mains power socket switch? (home automation)

<t>Quick update, I did some experimentation with the Virtual PI OS and can now control IR and RF Devices. As soon as the Physical PI arrives will test and post results up here then in theres enough interest will open up a dev site. Also eliminated the need for an SSR for the heating by soldering ont...

Re: Control systems and telemetry

<t>For the radio protocol, if its not going to control alot and speed isnt an issue I would use DTMF pulses at X interval (X being a suitable time for the quality of the signal eg. 1 second or 10 ms spacings depending on the clarity/interference) and use the sound card to recieve the audio and a sim...

Re: Project: RPi + RC Car

<r>I did consider an arduino on the car itself to control the motor and servos wih an RF serial module (you get speed control that way as well – as it is its just stop/go with the opto hack – you can use pwm and a transistor+capacitor for smoothing to control the cars motor speed) but would have bee...

Re: RaspberryPi + GPS

<r>The main issue with creating an RPi GPS system isnt so much the hardware but the software side. On the hardware side its most likely that you will be getting data via serial be it via the GPIO possibly with a microcontroller in the middle or through an FTDI chip on the USB.
