Assembly

Add Magnets to parts

The macpi-front.stl, macpi-body.stl and macpi-back.stl parts were designed to snap together with 1/4 x 1/16 inch Disc N48 magnets. These can be secured to the stand-offs with adhesives.

Always double check the polarity of the magnets! Be careful not to let these snap together, they are brittle and can easy break!

Mount PiTFT to Front Bezel

The macpi-front.stl part has three stand-offs for moutning the PiTFT. Position the PiTFT over the part and line up the mounting holes with the stand-offs.

Secure Mini PiTFT to Front Bezel

Fasten three #4-40 x 3/8" flat phillips machine screws to the mounting holes on the PiTFT.

Prep GPIO Cable

Attach the GPIO ribbon cable to the 2x16 socket on the back of the PiTFT.

Add GPIO Ribbon Cable to PiTFT

Remove the connector on the end of the ribbon cable with wire cutters. Peel apart #2 and #6 wires from the ribbon cable. #1 is the wire with the white stripe.

Secure Base to Body

Join the macpi-base.stl part to the macpi-body.stl part with the large opening facing each other and the mounting holes lined up. Fasten four #4-40 flat philips screws to the mount holes.

Prep Wires for Slide Switch

Measure three 26AWG stranded wire to about 8cm in length. Strip the tips and tin them. Secure the slide switch to a panavise jr. for soldering.

Solder Wires to Slide Switch

Connect the three wires to the slide switch by soldering the tips of the wires to the terminals leads on the slide switch

Seal Wires with Heat Shrink Tubing

Cut three pieces of heat shrink tubing and slide them over each wire to secure the connection with a heating element.

Install Slide Switch to Base

Insert the three wires throught he opening on the macpi-base.stl part with the slideswitch facing the outside

Prep Powerboost 500C for Slide Switch

Secure the Powerboost 500C to panavise jr. for soldering the three wires from the slide switch.

Solder Slide Switch Wires to Powerboost 500C

Solder the three wires from the slide switch to the GND, EN and Bat pins.

Solder Pi GPIO Wires to Powerboost 500C

Use a wire stripper to strip the #2 and #6 wires on the GPIO ribbon cable. 

Powerboost 500C Conencted

Solder the #2 wire to the Postive+ pin and #6 to the Negative- pin on the Powerboost 500C.

Prep JST Cable for Battery

Cut the male JST connector from an extension cable.

Solder JST to Battery

Carefully solder the postive and negiative wire conenctions to the male JST connector.

Mount Powerboost to Bottom Cover

Use two #4-40 flat phillips screws to secure the Powerboost 500C to the macpi-bottom.stl part.

Test Powerboost 500C

Plug in the male JST connetor from the battery to the female JST port on the Powerboost. Slide the switch on to test the power circuit. 

Test PiTFT

Check to see if the PiTFT powers on. If it does, congratulations! If not, double check your solder connections.

Position GPIO Cable into Body

Power off the circuit and unplug the GPIO cable from the PiTFT. Insert it into the base through the macpi-bottom.stl part and out through the macpi-front.stl part

Install Battery to Base

Insert the 6600mAh lithium ion battery into the macpi-base.stl part through the bottom.

Secure Bottom to Base

Position the macpi-bottom.stl part over the bottom of the macpi-body.stl part and line up the mounting holes.Fasten four #4-40 screws to the four mount holes.

Bend Pi GPIO Ribbon Cable

Gently fold over the GPIO ribbon cable so that it's position like in the photo above.

Install Raspberry Pi to PiTFT

Position the Pi over the PiTFT, align up the pins with the connector and press it down to make a complete connection.

Snap on Front and Back

Carefully snap on the front and back parts to the body. The magnets are pretty strong and secure the parts together nicely! It's easy to quickly remove the front or back and get to the internals.
