Re: PI4J + LCD

I'm slowly working on a high level java library to handle the Adafruit LCD Pi Plate in a way vaguely similar to JavaFX or Swing; scenes, menus, scrolling text fields, action handlers, etc. But it turns out I'm much dumber than I thought, and it's taking awhile, so don't hold your breath. I've got th...

Re: [Solved] Gmediarenderer and USB audio

I'll have to check when I get home on what I ended up with, but someone will probably chime in here before that, tho we'll need more information: 1. Are you using a USB audio device or the Pi's audio jack? 2. Can you successfully use aplay to get sound output? for example: aplay /usr/share/sounds/al...

Re: Your daily head/desk

"I told a friend that I have a Pi and his response was, 'Why didn't you just buy a cheap Android tablet?'" Well, the Foundation was predicated in part on combating just this kind of attitude. It should be encouraging to be reminded you're not tilting at windmills; it's serious problem you're address...

Re: Cache music from pi

BubbleUPnP for Android caches it's music I think, and the cached songs can be made available to the Android music library with a settings option, if I understand correctly. I'm not sure how it manages the cache. It will also let you download to the phone, but then you'd have to delete them manually.

Re: Alarm clock

I too use a Pi internet radio as an alarm clock, using cron, as has been suggested. I can also turn it off/on/adjust volume/change stations/etc. with a cheap, simple IR remote solution described on my blog here: http://www.dkographicdetails.com/myPi/?p=20

Re: Case incorporating AdaFruit 16x2 LCD Plate

Following with interest. It would be the perfect case for the upnp control point I'm working on.
Have you considered a version with holes for panel mount switches, or better a panel mount 5-way nav switch (if I could find one for less than the cost of the Pi itself)?

Re: GPIO - Circuit Monitoring

For a few bucks each, you can get GPIO expander chips, like this MCP23017 from Adafruit: http://www.adafruit.com/products/732 "You can set the i2c address by tying the ADDR0-2 pins to power or ground, for up to 8 unique addresses. That means 8 chips can share a single i2c bus - that's 128 I/O pins! ...

Re: I'm a noob in electronic, should I buy Rpi?

Start by lighting up an LED. There will be no turning back. Check out the Adafruit website Pi tutorials; they assume no prior electronics experience. Pretty soon you'll have more project ideas than time.

Re: How would I, permenant audio link?

I would look into Pulseaudio. It should be straightforward to loop the source (microphone) to a sink on another PA server. But as you've discovered, nothing is straightforward when it comes to audio in Linux. Someone should come up with a turn-key baby-monitor solution (with optional video) for Rasp...

I'm using BubbleUpnp on an android tablet as my control point, but that's probably not relevant. So far: 1. Gmediarenderer is installed and working, ...

I'm pretty sure space was not a problem, both cards are 8 Gig, and not far from Wheezy 2013-03-26. After the upgrade the FDX LED would blink three times, pause and repeat.

Problem solved, mostly. For an earlier project, I had loaded the lirc_dev and lirc_rpi modules, which by default use the same pin (GPIO_01 = BCM GPIO18 = P1 header pin 12) as the pi4j example. Unloading these modules (and disabling init.d/lirc) fixed the problem with pi4j. I don't understand why pi4...
