Re: Grove Gesture Sensor (PAJ7620u2) + Power Button

I apologize, I wasn't clear enough. The button is not (just) power-off button, it's also power ON. and for that I thought the only way was to short pins 5 and GND. I followed this guide:

Grove Gesture Sensor (PAJ7620u2) + Power Button

I'd like to connect a hand gesture sensing module, like this: https://github.com/eouia/MMM-GroveGestures/raw/master/IMG_0747.jpg I'm already using GPIO3 for my power switch with a button that shorts GPIO3 + GND. If I want to keep using the power switch, what are my options? Can I connect both the ge...

LED light from PC power button

Hi, I have one of these buttons . I've successfully hooked up the 2 power button pins to pins 3 and 4 in the GPIO and a few lines of python later I have a button that turns the device on and off (holding it for a few seconds to turn the pi off). That works great. The button also has an LED light. In...

Re: Button for Raspberry pi

Just to circle back to the original question, I'm looking for a momentary push button, one with 2 pins, to connect one pin to GND and the other to a GPIO, I'll then write the simplest python code ever to play an audio file once the button was pressed. That's the idea. And to have a few buttons like ...

Button for Raspberry pi

Hi, I've never connected a button to a raspberry pi, I want to build something for my boy (to add buttons to his toy kitchen) I want to keep it super simple, buttons with no led, I don't want to use a breadboard or resistors, I want to connect a button like in the schematics here: https://projects.r...

Power Control of PC (power on/off)

Hi, I'm trying to control the power of a PC, through shorting the power pins on an ATX motherboard. I'm looking for the simplest solution possible. I found this guide: http://www.instructables.com/id/Pi-Power-Remote-Power-Management-with-Pi/?ALLSTEPS And I actually tried it and it worked! My questio...

Quadcopter (drone) with FPV

I'm looking for a way to have a Raspberry Pi serve as a "ground station" for a quadcopter drone such as the DJI Phantom FC40 or the Walkera QR W100S or some other quadcopter of its kind. Basically, I want the Raspberry Pi to be able to receive the video captured from these quadcopters in near-real t...

Elegant breakout board solution?

I'm connecting a RasClock and a PIR sensor to the GPIO. For now, I bought the GPIO paddle board breakout kit which works fine but is really not elegant, as there are just too many wires dangling. I'm looking for a solution which I can contain within the regular case or something that will require mi...

Re: Adding a driver for RasClock [RTC]

For people facing the same problem, I now have a solution. As mentioned in the op, it turns out that the latest releases of Raspbian include rtc-pcf2127. It also turns out that the latest RasClock has a chip that's compatible with rtc-pcf2127, even though it's actually rtc-pcf2127a or rtc-pcf2127at....

[SOLVED] Adding a driver for RasClock [RTC]

I recently bought an RTC module, and read the instructions here: http://afterthoughtsoftware.com/products/rasclock the error I get when I try "hwclock -w" is "Cannot access the hardware clock via any known method.". I didn't overwrite the kernel as the instructions say here, this does not seem like ...

If you have unsaved/scripted changes you can backup first and diff after to find them.
I hoped for an easier solution. Ended up reinstalling Raspbian. Thanks.

Can't upgrade to latest version

I made a bit of a mess with my Raspbian installation. Everything worked fine until I tried to follow this guide for installation the RasClock: http://afterthoughtsoftware.com/products/rasclock The situation now is that I couldn't get the RasClock to work and right now all I want to do is go back to ...
