I'm getting this more and more frequently when trying to access the forum...just to let someone know

General Error
SQL ERROR [ mysqli ]

Nope, voltage is different. You should never feed your Pi more than 5.25 volts.

Next challenge: voice control! Although this would undoubtedly become less reliable as the evening progresses.

Douglas6

As long as you're slicing, are the cable wires color-coded? Though even that I spose could be non-'standard'.

Douglas6

Not easily no. From that product page:
"There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer"

My two cents. Converting mp3 (or any PCM) to MIDI is pretty much a non-starter, unless you're really determined. Better an FFT approach like danjperron pointed out.

Is there any more detail on this? I'm also looking to use an FBTFT FrameBuffer with JavaFX. I have Adafruit's pitft display and would like to put JavaFX on it. I'm C-challenged, and not sure if rebuilding OpenJFX is required or if that's even something I could do. At the moment, following Adafruit's...

The resistors are much too small and could harm your Pi. You do not want to try and pull 20mA from the GPIO pins. Re-read ame's helpful posts, and use 220-330 ohm resistors at minimum. I'm not sure what your plans for the speaker are; you'd need a lot more electronics to connect it to a Pi. Your bes...

Am i right in thinking the Model B is drawing too much power and somehow dropping the usb hub That would be my first thought as well. The camera is power hungry, and the model A is not, so that would jibe with your results. 1.5A is plenty of power, but not all supplies are equal. Try it again with ...

1. Python will search the directories that are listed in the sys.path variable for imported modules. I like to put common modules like the Adafruit ones in 'site-packages'. You can get a list for your environment by: >>> import sys >>> sys.path 2. If I recall, Python3 will not allow a mixture of tab...

CAn someone give me a brief description? RadioShack announced plans to close up to 1100 of its ~5000 stores due to poor sales and a $400M loss last year. You should be able to get details with a web search. I think it's sad (having spent a fair bit of my childhood trolling the aisles at RadioShack)...

I believe that action 'resets' the Pi by causing an abrupt power surge or dip. I don't think it would be a recommended reset procedure; I've seen warnings in this forum NOT to do exactly that. Might as well just pull the power.

Douglas6

I wasn't aware that RasPi was/is sold also at RadioShack... It is indeed. But more important to me is the odd resistor, transistor, op-amp, roll of wire, spool of solder etc. that I find myself in dire need of on a Saturday afternoon to continue my current Pi project, and that I have so far been ab...

A sad day in Makerville

You could script it with a very simple bash script, or use Python. Just wait for a GPIO pin to go high, and run the command, either directly (in bash) or using subprocess() (in Python). Then a another line of code to make sure the button doesn't do anything until you're done recording. Sleeping for ...

Douglas6

Something like this? You'll also need one of these.

Douglas6

I don't know much about the low-level details of I2C, but it sounds like you may be running up against the clock-stretching bug on the Pi?

Douglas6

The wiring will depend on the driver you're using, I'd recommend notro's (the last one) The Adafruit board can use 5 or 3v3 power/logic. The product page says that the maximum current draw is ~50mA, which is right at the limit of the Pi's 3v3 rail, but I assume that notro, unlike me, knows what he's...

Douglas6

on all the sites/forums i've been on not one person has had to install additional codecs for the bubbleUPnP server ... running on a Raspberry Pi? There may be a good reason for that. I wouldn't expect acceptable performance using the Pi to transcode on-the-fly, even with the necessary MPEG-2 codec....

Douglas6

Yes. For a Wi-Fi solution, Google 'Raspberry Pi hostapd' and take your pick. For Bluetooth, this post might get you started.

Douglas6

What types of formats are you trying to transcode from / to? Is it possible you need to install additional codecs on the Pi?

In preparation for installing Java 8, right?

Is avahi part of the standard distribution these days? I happened to notice it in the dmesgs, and sure enough it works. I don't remember installing it. Perhaps it came with Bluez...that, and the kitchen sink.

Douglas6

Gotchya. The CSR 4.0 Looks like what I bought from Adafruit, and that's known to work on the Pi as a (P)iBeacon. I've heard tell of some CSR 4.0 clones that aren't really CSR. I guess for £1.58 you can't go too wrong.

XBMC seems a bit overweight for audio only, and I'm not sure it's a UPnP renderer [EDIT: I stand corrected ], although it works great as a UPnP media server, so you would probably need to control it with JSON. MPD would be lighter and easier to handle, and I believe there's an UPnP plug in for it, i...
