    I really would like to do something like this. I am looking for small dc motors at this time. I do have a spare cluster case to start building it.

    I even have another idea for which I already have all I need. Use one of the plastic covers of the MPH gauge on top of the dash, and put a bright light underneat so the numbers can be projected to the windshield even in dailight (add brightness control to reduce it at night). Then the POV will be spinning drawing the pointing arrow only. Something similar to the yellow car's photoshop I posted below in this thread.

    I know a little about it but not much. What are you trying to do?

    Re: Home made HUD system

    The first picture is one of the best pictures my camera has taken of this project.
    Its hard to capture a complete picture due to the slow refresh rate.
    But if you remember It happened also with the VF display.
    Here you can see the 'flying' effect of the graphics.

    The second pic is how it looks in the car at daylight and shows the size of the graphics related to the standard gauges.

    Added a third picture to show the POV off. I put it temporarily in a piece of wood, because there is a lot to do with it yet, like adding the Bluetooth module to be able to receive the real information of the car.

    Re: Home made HUD system

    I can draw almost anything at this time.
    Before I put it permanently in the car I am going to double the resolution and re-design the PCB to make it self balanced, I mean, put the same number and type of components in both sides of center of the PCB.
    The left and right arrows in the pics will be connected to the turn signals of the car and will blink accordingly.

    Edit, there was room for a third picture, so here it is. This is how it looks w/o the turn signal arrows which will be normally off. Also it barelly shows the red LED of the base of the floating pointing arrow. It looks much better live.

    Its what all new cars use.


    I have been looking for a shift light or aftermarket tac for my 2011 Challenger. The tach in the dash is about useless.

    The have hud displays the usd the obd2 for data input. But that would be slow i would think.

    Controled area network, study hard before you add anything to existing circuits.

    Re: Home made HUD system

    I'm in love with this project as you can see.

    I put a screw with nuts as counterweight in the less populated side of the PCB, so I can adjust until I get perfect balance.
    So all the vibration is gone and it only sounds like a little fan.

    Re: Home made HUD system

    There are some more things to resolve.

    1) We can see a little blink in the numbers in the POV, we need a motor with higher speed or put two or maybe three series of LEDs. I already built a new PCB with LEDs in both sides so I can see if its going to be enough or need the third branch.

    2) A bluetooth pair should be easy to implement, but I got the idea of using the Opto-Sensor that detects the sinchronization pulse to send the data to display one bit at the time.

    I was more concerned with the mechanical installation than the way to send information to the POV. But with the vibration and light intensity control I added, I feel comfortable to go ahead with the next steps.

    Thank you all for reading!

    Re: Home made HUD system

    I finished the latest PCBs last night.

    The project will have two PCBs and two microcontrollers, one will be fixed reading the signals from the back of the gauges and the menu buttons.
    At the same time it will be passing the data to be displayed to the second micro in the spinning PCB through an infra-red wireless connection.

    I have that app from the 2nd pic installed on my ipod, It works pretty decent for a simple HUD for nighttime driving at least.
    What is that app?
