BIll of Material
Allways look for the cheapest seller, the Price may vary heavy!!! And look for Local dealers preferred. http://www.midibox.org/dokuwiki/doku.php?id=where_to_order_components
I was fascinated about the RGB Shaft of this Encoder so i developed all opon this nice piece. Its not the cheapest but i sell them for a reasonable price.
And its still possible to use a non Illuminated Encoder.

If its your first SMD soldering you can follow this on t1:58 : http://www.youtube.com/watch?v=5uiroWBkdFY I recommend to not buy solder paste, instead buy some flux-paste like this on Mouser: 590-8341-10ML
Start with the SMD parts and then go on the the conventional parts also on the Bottom side. Don't forget the R11,12,13. Then go on with the Topside and the LEDs before soldering the Encoder as last. Check the Connections with a Lens.
Connect the core on J8/9 to J1 of the VLR-8Enc board.
To make it work with MIOS .NGC File we need to know how the shift-registers are connected.
Inputs:
1# Encoder 1-4
2# Encoder 5-8
3# Encoder Button 1-8
Outputs:
1# RED Shaft LED 1-8
2# GREEN shaft LED 1-8
3# BLUE shaft LED 1-8
4# LED Ring Row 1-8
5# LED Ring Selct 1-8
6# LED Ring Select 9-11
Assuming that the VLR-8Enc is the first device on the chain of J8/9 we need to configure it like this:
