Position the tray over the frame and orient it so that the mounting holes are lined up precisely. You'll notice two sets of holes are positioned slightly different.
Insert the mini-oontz-tray.stl part into the mini-oontz-frame.stl with one end sliding in first. Make sure to line up the holes.
Position and rotate the Trellis so that the numbers are upright with the opening for the potentiometers. Group the jumper cables from the trellis and pull them through one of the opening of the tray.
Grab the 4x4 silicone elastomers and position them over the Trellis PCB. Orient the keypad so that the "nubs" are inserting into the holes on the Trellis.
Group the jumper wires from the potentiometers and fit them through the top large opening of the enclosure. This gap is appropriately sized to fit the 4 pots.
Position the mini-oontz-cover.stl over the mini-oontz-frame.stl with the mount holes lined up.
Place the cover down onto the frame and snap it shut. Use 6 #6-32 1/2' flat phillips screws to secure the cover to the frame.
Yey! The 6 screws keep the Trellis PCB and 4 potentiometers secured inside the enclosure.
Place the Leonardo over the mini-oontz-bottom.stl part and make sure the mount holes line up.
Use 4 #6-32 x 1/2' to secure the Leonardo board to the bottom cover.
Position the frame with the mounted cover towards the Arduino board. Make sure the openings are lines up to allow for the power jack and USB micro port. Connect the male jumper wires to the appropriate pins on the header of the Leonardo.
- SCL to SLC
- SDA to SDA
- GND to GND
- 5V to 5V
Ensure the orientation of the Leonardo is lined up with the enclosure so that the USB port has an opening.
With all the jumper cables connected, snap the enclosure to the frame. Use 4 #6-32 1/2' flat phillips screws to secure the two pieces together.
You can 3D print your own knobs or get some neat ones on the internets. I picked up 1/2' pot knobs from RadioShack.
Keep your mini UNTZtrument from going barefoot, give them little rubber feet! These small sticky bumpers are our favorite accessory for any electronic kit or device. They are sticky, but not impossible to remove.
