LUPITO Speed HUD

thingiverse

The Speed HUD displays your real speed in either kilometers per hour or miles per hour directly onto your windshield, no need to take your eyes off the road and it's more accurate than most car speed displays. It utilizes an Arduino controller, a GPS antenna, and a large LED display for typically less than 15 euros or dollars. Ludek Talian designed this project which can be viewed on instructables.com. Assembling and customizing it is very easy; I simply made a couple of modifications. However, I needed a housing for the Speed HUD so with the help of my friend Tommy, we created one. Pictures show an initial attempt using matte black PLA in draft mode but I will improve upon this later. All you have to do is build the circuit, print the box, and assemble it. The following modifications were made to Ludek's design: I used an Arduino Nano instead since I had a couple on hand. Power for everything comes through the Arduino USB port. No LEDs are used. Current flows from the 5V and GND of the Arduino. The following modifications were made to the box: A hole was drilled into one side for the USB cable going to the cigarette lighter. Several holes were drilled into the sides to vent the electronics.
