I finally got around to building that bluetooth speaker I posted a while back. I also just ordered two more speakers from ebay that I forgot I bid on and won. The parts list is listed here.
Steps: I wired up the main power through a potentiometer with a built in switch then to the led, amp, and bluetooth adapter. The audio in was wired in parallel to the bluetooth output in the input of the amp. the output of the amp was then connected to the speaker’s wires. The potentiometer’s pins were connected straight the the amp’s pot pins to allow for volume control.
I then cut out the speakers back and the back plate out of a piece of sheet steel. Drilled the holes for the usb mounts, led, and the potentiometer. Then hooked everything up, realized it wasn’t very loud, and then soldered some resistors to up the gain according to the sparkfun guide.
I got featured on Make for my AirPi speaker!
I built an AirPi Wireless Speaker. It consists of a raspberry pi, small amp circuit, powered usb hub, wifi adapter, bookshelf speaker, and a usb battery.
You simply turn it on and wait for it to boot up then you can play music from your itunes or iphone using airplay. I also have mpd and mpc installed so that androids can play music on it too.
It took about two weeks to complete and the instructions on how to install are posted below.

How-To After the break.
I updated my mounting a network drive howto to include using mpd and mpc to make a remote music player using a raspberry pi controlled from your android phone.
This works for me on my MyBookLive ethernet harddrive. I do this in order to play my music from my drive using mpd and mpc thanks to this post. I also use this app MPDroid on my android phone to pick the music.
Create a directory to mount to
Create a script to mount the na
mount -t cifs -o username=user,password=password //192.168.1.101/folder /media/stuff
Change the ip address/folder, user, andpassword to the applicable information
test if its executable
make it executable if not
sudo chmod 755 mydrivemount
copy it to init.d
cp mydrivemount /etc/init.d
sudo chmod 711 /etc/init.d/mydrivemount
execute the script at start up
sudo update-rc.d /etc/init.d/mydrivemount start 99 2
it now mounts the network harddrive at boot.

Diy ir blaster
I built one of these over the break while I was at my girlfriend’s parent’s house. Her dad has a Google tv and their new cable box wouldn’t work with its type of channel switching. He needed an ir blaster to change the channel through the Google tv. We went to best buy and thought that they might have a set for Tivo but alas they did not. I found this how to with a quick search, went to RadioShack, bought the few required parts, and built it. After I changed the settings in the Google tv it worked without a hitch.
I added an extra battery to my rayven, it can now be ran at either the stock 6 volts or over voltage at 11 via a small two position switch at the butt of the gun. (Taken with Instagram)
