 I use a Dremel (rotary tool) with a grinding disc to remove the nubs/​protrusions from my encoders. If you do not have this tool, you can use wire cutters and a lot of force... or call a friend who has some tools to help you. I use a Dremel (rotary tool) with a grinding disc to remove the nubs/​protrusions from my encoders.

 Place LEDs into the PCB. Take extra care when placing the LEDs into the PCB. In particular, the Step View LED is of a different orientation to others nearby. Attach the panel. Flip the attached PCB and panel. Lay it down with the panel slightly raised so the LEDs can fall into the holes (the switch caps and/or encoder shafts keep it raised). Use LED leads to position LED into the panel holes. Solder the longer leads of all the LEDs. Check all the LEDs are at the same height - ones that are not can be adjusted by pushing the LED while reheating the solder joint. Place LEDs into the PCB.

 I used 220 Ohm resistors for SmashTV'​s green 3mm LEDs and 220 Ohm for SmashTV'​s red 5mm LED (the "​Beat"​ LED).

 +Please use the following list to stuff your PCB accordingly (yet incomplete):​

 +|**Part**|**Description**|
 +|U1,​U2,​U3,​U4,​U5,​U6 |74HC165|
 +|U7,​U8 ​            ​|74HC595|

 +|**Jumper/​Connector**|**Description**|**Connecting to**|
 +|J1 | DIN/DOUT | to CORE/CORE32 Wiring 1:1 with J8/J9|
 +|J2 | DIN/DOUT | to additional control elements in the Chain|
 +|J3 | Beat LED| optional Beat LED connection (if not mounting LED to PCB)|
 +|J4 | Datawheel Encoder| to PCB using Wires |
 +|J5 | Datawheel Switch | (optional) for encoder with switch |

 +====== Trouble Shoot ======

 +to figure out that your problems with that pcb are softwareside (buggy firmware, or false hw-config), you can test all Buttons and LEDs with that firmware:\\
