Re: Control PC ON/OFF with gpio

In theory, ie I haven't tried it, but you could use a 2N2222 to switch the PSU on wire, often green, to ground. Given that this wire is connected to the motherboard, it should not represent a hazard. That said, you are dealing with something very close to mains so proceed with caution.

Re: Raspberry pi to turn 64 lights on and off through web ap

What are the lights - single LEDs, LED arrays (i.e. one light made up of several LEDs) or something else, possibly mains switching? Single LEDs can be controlled using something called Charlieplexing (Google will help). However the SE answer gives a simpler answer by using the MCP23017. How's your h...

No soldering required for this beta test - we'll send you a tested kit with the controller board already soldered - don't want any tears at bedtime by releasing the magic smoke that's inside every micro controller!

WANTED: Three beta testers for low cost robot project

I have a low cost (~£10) open source robot design that needs some independent testing to get the instructions & support materials ironed out. If you live in the UK (posting overseas is slow & expensive), can program GPIO at a basic level already, have a few hours to build (about 30 minutes), program...

Please can someone at Pi HQ add a page to the list here: https://www.raspberrypi.org/documentati ... iguration/ so that no one else has to go through this pain.

Whilst functional and still maybe useful, this emu setup has rather been overtaken by shipping Pi's and some direct Qemu offerings for Windows. 1.

Saying that a similar chipset is used in the iPod/iPhone3 isn't quite the same as saying that you can run Mac OS on it! Not by a long chalk!

Re: Is mu Pi a dud?

The most common issue is with the power supply. As above, if you can't see the green LED flashing even a tiny bit, then either the Pi has enough power to light the Red LED and nothing else or the card isn't talking to the Pi. The monitor/display is less often an issue. Can you try an alternative car...

Re: Trouble typing

The keyboard may work with other computers but the Pi is smaller and more picky.

Anything with a backlight probably has other bells and whistles - try a more basic keyboard and check your power supply is up to the job.
