  • Study the schematic diagram

  • Before jumping into the electronics part you need to get familiar with the circuit so it holds no surprises. This isn't too hard. Grab the schematics off github or the files section and take a look. I'll wait while you download and view the diagram.......
  • Get car reversing kit

  • Firstly you will need to get the £10 car reversing kit off ebay. The type you want has 4 ultrasound transducers. You don't need the ones with video cameras etc. Beware that the control circuit will need some modifications which will stop it working...
  • Clock in a Box

  • In order to access A4 and A5 of the Arduino, you will need to solder two (2) headers onto the board (at least on my version). I used male right-angle headers to save space.
  • Mounting the ESP8266

  • I use a Wemos ESP8266 board mounted on a small piece of veroboard to connect the ESP8266 to the relevant pins on the mainboard I2C connector.  In my case I use GPIO12 and GPIO13 (SDA A4, SCL A5) for my interface.
  • Connect all hardware components

  • Connect the accelerometer to the Arduino Mini VCC -> VCC GND -> GND SCL -> A5  SDA -> A4  Don't connect the battery, we will have to power up the Arduino Mini and upload the code first using an FTDI basic USB converter
  • Connections

  • Mona Lisa ParaFoil

  • First you need to create a paper template. I used A4 white paper. I drew my lines for the angles of the wing shape on it. Including fold lines for the aerofoil shape.
  • Download it

  • The instruction set is available as PDF for A4 and US Letter size paper, as well as a ZIP archive of the raw images. It's in the FILES section...
  • Gas Sensor For Emergency Workers

  • Attach the MQ2 signal pin to Arduino pin A0 as defined in the code here:Attach the VCC and Ground pins of the MQ2 sensor to supply and ground. Using the custom PCB this is done for you here:The fourth pin is not needed but you could use it for the digital...
  • Spectrum Analyser Code

  • SchematicHere is my strip-layout for the version that I built:Notes:The three inline black circles (pins) above the resistors are for the two pin shunt. Short the upper pins and the LCD lights up. Short the lower pins and the LCD does not light.The project...
