Pico IIDX - Beatmania IIDX controller

Features:

• It's thin, really thin.
• Turntable and keyboard are separate.
• Magnetic connector.
• 1000Hz polling rate.
• HID lights, of course!
• Multiple turntable effects.
• Many live settings.

Thanks to many respectful guys/companies who made their tools or materials free or open source (KiCad, OpenSCAD, InkScape, Raspberry things).

Caution

This is a difficult build, much more difficult than my previous Pico Popn project:
https://github.com/whowechina/popn_pico.
I suggest you to build the my Pico Popn first.
This Pico IIDX project:

• Heavily depends on 3D printing, both FDM and SLA (resin).
• Requires skills to solder tiny components and thin cables.

Move forward only if you're REALLY interested.

This README documentation is still in progress.

HOW TO BUILD

Turntable Materials

• 1x AS5600 hall angular sensor board set (23mm*23mm)
  
• 1x 6mm*2mm magnet (must be radially magnetized), normally comes with the AS5600 board set.
• 1x 61804-2RS deep groove ball bearing (20x32x7mm), normally < 5US$;
• 3x M4*10mm screws (large flat head is better) and hex nuts.

Keybard Materials

• 1x Raspberry Pi Pico.

• 11x Kailh Choc v1 or v2 keyswitches, to get better play feel, 7 of them should be 50g linear.

• 7x Kailh low-profile stabilizers.

• 2x Panasonic 6mm square tactile switch EVQP1K05M.

• 1x USB Type-C socket (918-418K2023S40001 or KH-TYPE-C-16P)
• 11x WS2812B-3528 RGB LEDs or if you want more challenge: 28x WS2812B-1516.
• 1x 0603 5.1kohm resistors for USB.
• 2x 0603 10ohm resistor.
• 5x 0805 1uF capacitors.

Detachable Cable

• 1x HDMI cable (ultra slim, diameter < 4mm), at least 50cm in length, we'll cut the HDMI connectors off, so pick a cheap one.
• 2X Magnetic pogopin connector sets, male and female. PCB side should use ones with 90-degree pins, cable side use ones with straight pins.
