Re: Dual SD Card Slots?

One, this is a bad idea as another poster mentioned because of the flimsy SD card slot. Especially if you have a bunch of random people inserting cards, it would break really quickly. instead you should use something like http://www.amazon.com/IOGEAR-Pocket-Memory-Reader-GFR209/dp/B001AW8W7A/ref=sr_...

Re: Smaller RPi board without ports

You can also completely avoid the micro USB cable by powering via the GPIO pins. This would reduce the width some as you can have the power come from above the board instead of from the side. This does carry some risk though as you will bypass all of the onboard fuses/protections. Honestly though fo...

Re: GPIO input

There is a nice example from adafruit's internet of things tutorial. They have a button that has a single press as well as a hold timer. It is basically a python script that runs in a loop forever in which that script monitors the button and then runs different things depending on if it was pressed ...

Re: RaspBerry Pi(e) Model C (imaginations & wants)

My simple wish for the Rev C is a more fleshed out GPIO pin setup. Perhaps a chip that adds very fine control to the GPIO with more exact timings. E.G. You send a timing unpredictable signal to this chip and it produces the required output on the GPIO in a very time centric manner so that the RPi ca...

Re: Using my old phone's display for RPi?

Why not do a VNC connection? get an OTG cable if you want a keyboard (<$5) and use one of the multitude of VNC apps and then you are done.

Thank you so much for the help. It works perfectly now.

Re: Servo responding sporadically/inconsistantly

You need to connect a Pi ground (say P1-6) and the servo's ground. Otherwise there is no circuit to allow the gpio's control signal to flow through the servo. Oh god. I feel stupid now. I would assume the best way to do that would be either a breadbord or to splice a connection to the negative pole...

Servo responding sporadically/inconsistantly

So I am using a Tower Pro MG995R servo. I have it hooked up to pin 18 on my pi, and its power is hooked to a 5v 2000mA power supply (That I know works after testing extensively with a different project). I am using the RPIO PWM library to try controlling it. The problem I am having is that on occasi...
