Re: Don your testing hats, it's WiringPi2-Python
Managed to compile onto Arch. Found a couple of build issues that had snuck into the PiPy package and fixed them. Eeek! If anyone has had an error about a missing README.rst, it's now fixed. Compiling for arch needs: pacman -S base-devel, along with the usual requirements. Except Python-dev headers...

Re: Ultrasonic distance sensor...
I've got one of those Ultrasonic modules. I used a simple resistor divider to convert the 5V output to a more Pi friendly 3V I tried this but failed at first as I was using resistor values that were too large. The input then floated high and never went low. I replaced them with lower values (<1k) a...

Re: AirPlay
In case anyone needs, you can direct the audio output to a usb soundcard by using the following:
That is assuming you have a usb soundcard plugged in card 1, device 0 (check with "aplay -l")
Code: Select all
sudo ./shairport.pl -a AirPi -ao_devicename=plughw:1,0

Well if you are interested in proper sound, you can use the audio out to drive a speaker, this is just an experiment, but easy to set up.

Piezo Transducer
I purchased a cheap (£1) piezo transducer, wired it up through a pot (for volume) to the 3V3 and a GPIO pin. I used the python RPi.GPIO module and made a basic script to work the piezo. And of course I had to add some flashing LEDs in the mix! See the video ( mov ) import RPi.GPIO as gpio gpio.setmo...

Re: help and advices for a sailboat telemetry project
Here are a couple of useful links for i2c: http://elinux.org/Interfacing_with_I2C_Devices http://www.acmesystems.it/i2c If you install the i2tools package, you can use "i2cdetect -y 0" to see if your device is wired in correctly (the address will appear in the table). With a bit of trial a...

Re: Keyboard Typing Problem [Power?]
I bought the Perixx 707W wireless mouse and keyboard. I did have issues with repeating/sticky keys, but they were solved by shorting the polyfuses next to the usb port (I used a crocodile clip to test this first). If your Pi has these polyfuses (the newer ones have 0Ohm resistors I believe), it may ...

Like Plugs7, I bought the Anker Astro-3 10,000mAh for £33 (Anker, EasyAcc, PowerGen and a few other companies seem to sell branded versions of the same hardware, so shop around). There are also various other versions of various sizes and mAh with/without LED torches etc (use the dropdown box on Amaz...

Re: Automatic setup for RTL8188CUS based wifi adapters
Having no success so far with Berryboot, I decided to check my wireless usb dongle (a TRENDnet TEW648UBM) with the standard Debian build. I ran a fresh install of 2012-08-16-Wheezy, which comes out as kernel version: Linux raspberrypi 3.2.27+ #66 PREEMPT Fri Aug 24 23:52:42 BST 2012 armv6l GNU/Linux...

Re: Berryboot v1.1 - Boot menu / OS installer
Does Berryboot only work with squashFS or can I use root file systems on different partitions also? Only support SquashFS/aufs for now. I did some experimenting with using BTRFS without SquashFS the other day, as that also allows you to easily put multiple distributions inside the same partition, a...

Re: Automatic setup for RTL8188CUS based wifi adapters
Looks like a nice tool.
But it has a problem when it lists the wireless networks, I get a list of one:
wlan0 interface doesn't support scanning
My dmesg also has the following line after the usb adapter:
8192cu: disagrees about version of symbol module_layout
Any ideas?
