Here is a great way to stay up on your math skills and entertain yourself on a hot summer day!
Wait 30 seconds for lost tourists and…..
You know that awesome feature in Gmail where it shows you the first couple of lines of an email so you don’t have to open it letting you ignore a bunch of emails you don’t want to deal with.
It looks like this:
That is great unless you REALLY want someone to open the damn email…
If you make the top three lines:
The answer is very simple! We used a VCA Mixer. Specifically the Vestax PMC-07 Pro. Because you know… we’re pro like that.
Well, I’m glad you asked. Allow me to explain: VCA or Voltage Controlled Amplifier means that instead of sending the audio signal to the crossfader the mixer instead sends a voltage which in turn controls the volume level for each channel. This makes determining the position of the fader very easy; simply measure the voltage for each channel.
Because we’re so damn pro and didn’t have any of the parts to make a proper Y cable we just soldered everything to the crossfader.
The Arduino sketch we used can be found here.
In summation here is a list of items you must procure to do this:
Build your Y cable. Make a couple voltage dividers. Hook it up like the picture above and BLAMO!
#Pro-Tip: Elliot Marx informed me that if you use an Innofader (the origional, not the Pro or PNP) it will limit the VCA voltages of the PMC-07 Pro to 5V eliminating the need for the voltage dividers. Wire colors for the Innofader are as follows:
Blue = 5V
Green = VCA1 (varies from 0 to 5 volts)
Yellow = VCA2 (varies from 5 to 0 volts, moves opposite from VCA1)
Grey = ground
Thank you Elliot!
Lack talent? At least you gear can be FFFFFAT!
