Re: Controlling a coffee maker with Raspberry Pi

Looking at the connector you were asking about. On the pcb side my guess is that the top one is power (probably 5v) the second one down is ground. The next two pins are likely to be sensors for the machine so that it knows when the coffee is ready.

Re: Controlling a coffee maker with Raspberry Pi

Looking at the PCB. It seems that the on switch is activated by pulling the pin on the chip to ground. The best advice is to use a relay between the pi and the button.
The gpio will trigger the relay. This will complete the circuit on the button side which will switch on the coffee machine.

Raspberry Pi in a NES cartridge

Finally the A boards were released and after much desoldering and reshuffling I've finished a project to turn a NES cartridge into a usable Pi case. It features a 4 port hub with 2 internal and 2 external USB sockets, a combined AV jack and a nice blue LED light to show that there is power. IMG_1537...

Re: Minimum power supply for a complete media centre

I'm sorry I didn't mention that I'm using the power supply for the hub and powering the pi from said hub. Also I'm not powering the pi from the gpio pin. I'm using the micro USB power connector.
So it goes
Power supply -> hub ->pi and other peripherals

Minimum power supply for a complete media centre

I've been testing many peripherals and hubs to make a stable raspbmc media centre and have come to the conclusion that the minimum power requirements needed for a system that uses a 4-port usb hub that powers the pi, a wireless dongle, keyboard/remote control (If needed) and a 2.5" external hard dri...

SCUMMVM on Raspberry Pi

Hey guys, I've had my Pi for a couple of weeks now and have finally managed to sit down and really play. Anyway I've managed to compile the latest SCUMMVM program for Raspi and can happily confirm that it works. I'm not sure about some of the features just yet as I need to find all my old game discs...
