Full Build Instructions for pi-Stomp v3

• By building and using a pi-Stomp kit, you assume all responsibility
• Tree Fall Sound LLC cannot be held responsible for any damages or injury which may result during assembly or usage
• Tree Fall Sound LLC will provide support but cannot be held responsible if your build does not function as expected
• Official terms and conditions

• As shipped, many hardware pieces are used to secure the PCB in the enclosure. While dis-assembling you might want to have a tray or shallow box underneath to catch falling washers, etc.
• Click on any photo to enlarge
• A small Phillips screwdriver is needed
• Fingers can be used instead of a wrench for the hex-spacers, jacks and encoder hardware. If you do use a wrench, only lightly tighten.

First, it's important to identify the parts for assembling the PCB (Printed Circuit Board).

Note that for hardware id's the number corresponds to the length or thickness (eg. N2 : 2mm thick nut)

Other than the footswitches, most parts of pi-Stomp mount to the pi-Stomp PCB.

Three other boards (Audiocard, LCD and Raspberry Pi) will plug into the pi-Stomp PCB and then are secured with nylon hardware.

The front side of the PCB has the encoders (knobs), the back side of the PCB, looks like this:

The Pi will be held in place with 4 long H15 (15mm) hex spacers plus a 1mm washer, at the locations shown

• Insert a short S6 (6mm) screw from the Front side of the PCB
• Add a W1 (1mm) washer from the Back side of the PCB
• Twist on a H15 (15mm) hex spacer and finger tighten

Repeat for the remaining 3 spacers

The Audio Card (DAC/ADC) will be held in place with 2 H10 (10mm) hex spacers at locations shown

• Insert a short S6 (6mm) screw from the Front side of the PCB
• Twist on a H10 (10mm) hex spacer and finger tighten
• Repeat for other hole
• Do not plug-in boards yet

Attaching the Raspberry Pi Active Cooler

Remove the cooler port protection plug (can discard that)

Plug in the active cooler (the plug is directional)

Flip the cooler and remove the sheet to expose the blue adhesive pads

Align the cooler pins, stick the cooler down, push down the two spring loaded pins until the barbs grab and the cooler is secured.

Add four S10 screws as shown

Add washer W1 then nut N2 to secure all four screws to the LCD board. The washer + nut is used to provide the proper spacing between the LCD board and the pi-Stomp PCB.

The order matters!

Place the LCD, insert protruding LCD screws into the holes on pi-Stomp board.

Flip the board, Attach 3 nuts (N2) from the back side of the PCB. Tighten (by finger or pliers)

Connect LCD using J8 Jumper

Note that you'll only connect the top 8 pins of the LCD header which will roughly align with their connected pin on the pi-Stomp board. Connecting the wrong pins can cause damage to the pi or LCD.

Connect the other end of the Jumper to the pi-Stomp PCB

Make darn sure the 3-pin sockets on either end of the card connect to the corresponding pins on the pi-Stomp PCB.

If by chance, your card didn't include the 3-pin sockets, please email support@treefallsound.com

Secure with two S6 screws

Plug it in as shown. Make sure all 40 pins engage correctly

Secure with four S6 screws

Note: At this point, you could boot it up or wait until it's all mounted in the enclosure.

Insert lens (LL) from the top side, secure with retaining ring (LR) from the back Repeat for all 6 lenses

Add a Nylon Encoder Washer (EWN) to each encoder

If you haven't yet, remove the protective film from the LCD.

Tilt the PCB vertical and add a Jack Washer (JW) to each of the 4 I/O jacks

While performing quite the balancing act to keep the washers on, insert the PCB into the Enclosure as shown

Add a Jack Trim washer (JT) to one of the I/O jacks, then a Jack Nut (JN). Finger tighten to pull the PCB toward the enclosure

Add a metal Encoder Washer (EWM) to one of the encoders, then an Encoder Nut (EN). Finger tighten to pull the PCB towards the enclosure face.

The PCB should be positioned well now. Add the hardware similarly for the remaining encoders and I/O jacks.

The soft-touch encoder knobs (EK) are splined inside.

You might need to rotate the knob slightly while pushing towards the enclosure until the splines align and the knob fully seats onto the shaft.

Installation Instructions

Once you've booted up and verified that everything is working.

You may need to smush down the LCD ribbon cable if it resists the enclosure from coming together.

Secure with the 4 metal screws.

Stick on 4 rubber feet if desired.
