Audio switcher

I’ve been looking for a while now to find a way to switch between multiple audio sources and output them on my speaker system.

Finally, I decided that the simple way is the best way :), so there’s what I came up with.

This is a 3P4T switch with four 3.5mm stereo female audio jacks acting as input and a 3.5mm stereo female audio jack that outputs the selected channel to the speakers. The knob points to the channel that is selected. Audio sources in this photo is my main PC and a Media laptop used for watching videos. There’s still two unused inputs left for connecting my phone/tablet/etc.

Now some photos from the build process:

I’ve spend approx. 100 DKK (17.5USD) for the parts (box, switch, knob, audio cable) that I did not have in my spare parts bin, but also had lots of fun building it, so, to my mind, it was worth the price.


Galaxy Nexus ADB drivers

So, I got this awesome phone (Galaxy Nexus I9250)  some time ago, and I had been fighting with the drivers for ages… Approx an hour ago for some reason ADB on my laptop (Asus N53SN) lost connection to the phone. After reconnecting it Windows (7 Pro, x64) showed that device was not recognized.

After doing some googling I managed to get it working again. Seems that EU version of the phone has no drivers available directly from Samsung’s site :(. While googling I came to this site: Seems that one has to download drivers for US Verizon version of the phone. Link for the main page:

After downloading the drivers, run the “Verizon_Wireless_I515_Galaxy_Nexus_USB_Driver_v1.4.6.0.exe” and let it install. After drivers have been installed connecting the phone to the computer should result in it <phone> being recognized correctly.

Yay, success. Hopefully this can help somebody that is facing the same problems.
