Connected-Oldtimer
The aim of this project to modernize my old Volkswagen T2 by adding sensors everywhere and make it part of the internet of things. This project is not vehicle specific and can be implimented in any pre OBD vehicle.
The goal here is first to make remote monitoring possible. Motion sensing for anti theft will be implemented as the vehicle does a lot of sitting. (my bicycle has x4 the ammount of kms per year on it as the bus). Additionaly the ability to remotely view levels (battery charge, fuel level etc..)
Alongside remote monitoring I have implmented an HMI using a 3.5" Display that fits in the dash area originally inteded for the RPM guage. This display shows the instantanious data such as speed, RPM, and Temperature.
A low speed CAN network is set up throughout the vehicle to easily add extra sensors.
Disclaimer: Still in the developement phase. V1 hardware has been created and software is still in heavy developement.
Software used:
- Visual Studio Code w/ Particle Workbench Extentsion🤘
- Particle Cloud
- BusMaster
Things implemented:
- 3G Connectivity and vehicle to cloud data transfer
- Gps velocity and location tracking and display
- CAN Bus Sensor Data
- Movement Sensor
- 3D Printed Display mount (Thingiverse)
Parts List:
- Particle Electron
- Nextion 3.5" Display
- Adafruit Ultimage GPS

To create a GPS simulation, first create an NMEA file in NMEAGen. after generating a .nmea file, change the file extension to .txt. The file can now be played in the Serial Output tab of SatGen.
Any USB to TTL coverter can be connected to ports C0 & C1 (Serial5) of the Electron.

Questions
How big is the Connected OldtimerHardware PCB?
It measures 115.9 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Connected OldtimerHardware use?
27 parts, built around the TSR 2-2450 and SFH618A-2. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Connected OldtimerHardware KiCad files?
From the theHeathLee/Connected-Oldtimer repository on GitHub, at the commit this page was made from: the board is Hardware/Connected-OldtimerHardware/Connected-OldtimerHardware.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Connected OldtimerHardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask theHeathLee before reusing the design.
