Constructing the X-POD

The C5duino PCB V2.0 plus LCD Touchscreen

The X-POD is split into 2 components. The control box (C5duino) and the display (Touchscreen LCD). The control box is mounted at the read of the C5, in the same position as the original C5 control box. The display box is attached to the front where the C5 POD is located.

Control Box

First we shall start with the control box as this is the most complicated. I have designed and printed a custom PCB which forms the basis of the control box. You will need to purchase the components listed below and slder them to the board.

Control Box Component List

To help sourcing the components needed to build the control box I have provided links to the relevant items on Ebay. It is up to you where you get your components from, the links I provide are purely to show you the item I am talking about.

These components need to be soldered to the control box PCB:

When you have all the components this is where they need to go on the PCB:

  • IC1 = Arduino Nano
  • R1-R9 = 10kΩ Resistor
  • R10 = 3.9KΩ Resistor
  • R11 = 100kΩ Resistor
  • D1-D3 = Diode 1N4001
  • TR1-TR5 = IRF530 N Channel Power MOSFET
  • RD1 = Reed Switch
  • CURR = Current Sensing Module
  • T-INT = LM35 for Ambient Temperature

Additional components for the control box. These are not soldered to the PCB but rather will be connected to the PCB:

When you have the above components they need to be connected to the PCB:

  • IC1 = Arduino Nano
  • RTC = RTC Module
  • RD1 = Reed Switch
  • CURR = Current Sensing Module
  • T-EXT = LM35 for Motor Temperature
  • RLY = Motor Relay

Electrical Cable

To connect everything together you will need the following cable:

  • 4 Core shielded cable (2m)
  • 70amp rated cabled for the motor conenctions
  • Suitably rated cable to connect lights/indicators to the control box

LCD Display

Construction is much simpler than the control box, the only modification needed is to create a connection between the VIN, GND, TX1, RX1 on the Arduino MEGA to allow a connection to be made to the control box at the back of the Sinclair C5.

To help sourcing the components needed to build the LCD Touchscreen I have provided links to the relevant items on Ebay. As usual, it is up to you where you get your components from, the links I provide are purely to show you the item I am talking about.

The Arduino Mega

The pins highlighted below need to be attached to the 4 way connector. I did this by running 4 wires from each pin to a small PCB stripboard which had the connector soldered on.

Arduino Mega Pin Connections

The wiring of the connector must match the connector on the control box circuit board, except TX1 & RX1 must be reversed. So TX1 on the Arduino Mega must be connected to RX on the control box board and RX1 (On Arduino Mega) must be connected to TX on the control box.

Ride a Sinclair C5 and jump as high as possible. Do mid-air spins for more points.
