Parts

None of these parts are fitted yet.

Core

• Raspberry Pi 5: the computer. It sits on a printed tray in the main compartment, behind the keyboard.
• KBDcraft Kit Adam keyboard: a 60% hot-swap board (UK ISO layout) that normally lives in a LEGO-compatible brick case. Here it clips onto LEGO studs printed into the frame.
• InnoLux N070ICG-LD1: 7" 1280×800 IPS panel with an HDMI driver board kit, in the screen lid.
• Pimoroni Trackball Breakout (PIM447): the pointing device, in a thumb pod on the right-hand side, connected over I2C.

Power

• DeWalt 18 V XR battery in a DeWalt battery dock with switch and fuse, on about 1 m of cord.
• GX16 2-pin socket and plug: the power input, in the hand-hole behind the handle.
• Mains option: a 20 V adapter that slides into the same dock, or any 19–20 V laptop charger via an adapter lead.
• Planned: reverse-polarity protection, a 5 A fuse, a MOSFET power switch driven by a 12 mm latching LED push button, a low-voltage cutoff, and buck converters for 5.1 V (Pi), 5 V and 3.3 V (bench outputs) and 12 V (screen, if needed).

Mini lab (side bay)

• Half-size breadboard on the bay's back plate.
• Header block: power and GPIO headers above the breadboard.
• Jumper tray on the inside of the bay door.

Back I/O panel

• 3 mm black acrylic panel, laser cut and engraved, swappable.
• Panel-mount HDMI, RJ45 and two USB extension leads.
• 4 mm banana sockets for 5 V, 3.3 V and GND.
• Two mini-XLR 5-pin sockets (BUS-A and BUS-B).

Printing and hardware

• PLA for every printed part, printed on a 220 × 220 mm bed (the frame is split into three sections and joined).
• M4 heat-set inserts and M4 button-head screws for the keyboard trim strips; M4 × 14 socket caps for the middle–right frame joint.
• M3 × 3 short heat-set inserts for the bolt-on panels and the trackball pod.
• Hinge pins: M3 × 16, M3 × 14 and a plain Ø3 × 34 mm pin.
• Olive webbing for the lid straps and a 38 mm shoulder strap.
