New illuminated safe shutdown switch

Hi everyone, just thought I'd post an update that I've created a new, illuminated safe shutdown circuit for the Pi. Press the LED for 2 seconds and it instructs the Pi to shut down safely via GPIO. Once the OS has completely shut down, the circuit removes power. Press again to boot as normal. Holdin...

Re: Powering from a car battery + additional temporary power

I currently have a car power supply for the Pi that connects to the ignition, +bat and -bat and safely shuts down the Pi when it senses that the ignition has been off (then cuts power to the Pi).

Re: Power switch now available for Pi

Hi guys, just letting you know that the 2amp car power supply / switches are now available at http://www.mausberrycircuits.com
The 3amp and dual-USB (for a self-powered USB hub) will be ready in 10-14 days. Thanks again!

Re: Power switch now available for Pi

Hello everyone! Just wanted to give an update, my Kickstarter campaign has finished and I've now got a website up at http://www.mausberrycircuits.com where you can get the setup script and also purchase switches (official purchase page up soon). Thanks for all the support! I also have almost complet...

Re: Power switch now available for Pi

Hey guys, just an update - I've put my project on Kickstarter to make the production process a little simpler. Cost had to go up a little since I've included free shipping and the assorted fees.

Re: What's the simple and safe way to do a "shutdown" button

Hello! Here is a link to the power switch I've created.
http://www.raspberrypi.org/phpBB3/viewt ... 63&t=32435

I've got a new run of boards being printed now and they have shrunk the switch to almost half the size of the one in the demo video/photos.

Re: Power switch now available for Pi

Does this do the same thing as an LTC2954 + MOSFET? Basically: when the RPi is powered off, push button briefly to turn it on. when on: push button briefly to signal the RPi. When it is ready to shutdown, it sends a signal to the switch to turn power off. push button for N seconds to force power of...

Re: Power switch now available for Pi

You plug your original Pi power supply (male micro USB) into the switch. Then use a standard USB->micro-USB from the switch to the Pi's power port. The GPIO pins are only used for communication, not powering the Pi. One lead sends a signal to the Pi and the other lead receives a signal from the Pi. ...

Re: Power switch now available for Pi

I can definitely do that, I designed the boards with two plain solder holes where the switch is. You can use whatever type of switch and wires you'd prefer as long as it's not a momentary switch (must be steady state on or off, like a toggle or rocker switch). I may eventually update the code on the...

Re: Power switch now available for Pi

Sure, I will ship to Portugal. I think USPS international would only be about $7 since this is such a light item

Re: Power switch now available for Pi

If you guys are interested in the switches or want some which are somewhat customized to your setup then just send me a message and I'm sure I can easily modify these as necessary. Also, I just wanted to mention that if you total up the cost of the components + printing the PCB + time spent solderin...

Power switch now available for Pi

Hey guys, I have finished creating a hardware power switch for the Raspberry Pi that communicates with the Pi. It has a micro-USB connector on one end that your normal power supply plugs in to and then a USB port for connecting the Pi to. It uses two leads that connect to GPIO pins and a short scrip...
