  1. OpenHUDisplay • Ever wanted to have one of those fancycars with HUD for speed indication? • Now you can!Simply download this software andbuild a fairly simple circuit! • Source code and documentationavailable for free at:https://github.com/Djhg2000/OpenHUDisplay

  2. Why OpenHUDisplay? • Based on off-the-shelf components- Which makes them easy to find • The software and it's source code is available- Completely free and easy to download • If you want to change it's behavior - You can!- Actually, you're encouraged to do so • If anything breaks you easily can fix it at home- No need to wait for tech support to find the issue

  3. How it all works • You can connect a regular serial GPS through a MAX232 family RS232-to-TTL level converter chip or a GPS module with TTL signal levels directly • The PIC then captures and formats the data to suit your needs • The formatted data is then sent to the Futaba M12BY02AA VFD driver (or compatible) • The driver then mirrors the characters before they're sent to the VFD itself

  4. Block diagram (hardware)

  5. Additional features • Brightness adjustment through hex code switch • Optional automatic brightness settingis work in progress • Displays time as well as speed • DST setting through switch

  6. Approximate cost to get started • A PicKit2 starter kit is recommended, however for the final circuit only the PIC16F690 will be needed363 SEK • MAX202ECPE RS232 transceiver (if RS232 GPS)54 SEK • Futaba M12BY02AA VFD167 SEK • Various components (switches, capacitors, etc.)~80 SEK • Total cost: ~664 SEK* = ~€72* = ~$95**Current prices from www.elfa.se, currency exchange rates may vary

  7. JSP diagram (software)

  8. Future of the project • Completely open source • Anyone with basic electronics skillscan build their own • Anyone with programming skillscan improve the code as they see fit • Useful links on next slidekeep your cameras and notebooks ready

  9. Useful links • Source code and documentation:https://github.com/Djhg2000/OpenHUDisplay • Tutorials on SparkFun:http://www.sparkfun.com/tutorials/ • Free documentation on NMEA0183:http://gpsinformation.org/dale/nmea.htm
