Re: Controlling my central heating

I'm pretty sure you could - thermostat is essentially a fancy switch based on temperature - see if you can find a manual for it online, or work out what the outputs are doing by using a multimeter. Be careful though - always assume everything could be using mains voltage!!! In relation to my origina...

Re: RPi.GPIO Wiegand capture speed?

I made my prototype with a piPlate - It is nice and compact! Don't know how durable it is though, and the cabling looks like a bit of a rats nest! Do you think you'll continue with the the firtzing pcb KH? If not, would you consider sharing what you've got so far? Might help with my learning! Totall...

Re: RPi.GPIO Wiegand capture speed?

kghunt/irish... Did either of you ever look into a PCB shield for the pi that would attach to the pi? Using code from this thread, I managed to get the pi reading cards fine, then also integrated it with our active directory system at work (That's the system that manages usernames, passwords etc on ...

Re: PiFace & Wiegand RFID reader

Might have to be my next port of call, rather than using the piface, to see if that is where the issue lies. Is there much difference between your suggestion and wiringpi? I'll need to reduce my data0 and data1 lines from 5V to 3.3V - I can just use a 2k2 resistor and a 3k3 resistor to create a volt...

PiFace & Wiegand RFID reader

Hi All, I'm attempting to build a system to detect who is in the building by having a RFID reader to enter and exit the doors of our building, using Pi, PiFace, 2x Wiegand RFID readers. I'm more programming/networks orientated than electronics, so I thought the easiest/safest way to connect stuff up...

Re: How to identify which RFID it is

I have a similar issue... USB keyboard emulating reader doesn't seem the right way to go....

I've ordered a wiegand rfid reader that I am going to try and wire to my piface board, then write a program to decode card numbers...

Re: RPi.GPIO Wiegand capture speed?

Hi guys, A little late to the party, but just ordered another pi, piface, wiegand rfid reader, and door strike. Plan is to make RIFD entry system, where the pi checks with against a Microsoft Active Directory server to find if the card is registered to anyone, check if their account is active, and o...

Re: Controlling my central heating

@iganin - I don't use SMS... The iphone just goes to a php web page on the pi, where I can control it from. @graham - You're totally right. Fix the root cause, rather than spend time developing a workaround. I'll get it serviced! Project is working quite nicely so far! I'm trying to think what else ...

Re: Controlling my central heating

@lucdig - The relay board takes a connection from the 5V connector and the ground to use as its power sources. Then you control each relay by connecting one of the other pins to gpio connector on the pi, so they are controlled with the 3.3V but powered by the 5V...Well, that's my understanding anway...

Controlling my central heating

Hi Guys, Going to do my first proper RPi project shortly, controling my central heating with it... There's two distrinct areas... 1) Ability to turn heating on and off. Should be easy (I think), I've ordered an 8 channel relay board (http://r.ebay.com/7Vab5n). I'll set my heating to be always on, th...

bulb matrix... with real bulbs

Hi guys, I'm thinking of cool installations for a music festival... I want to build a 6x6 large wall sized matrix of regular 240v light bulbs, then have an array of toggle switches located 20m away from the wall, where people can toggle the switches to design patterns on the wall... Maybe then have ...
