16.04.2023 some USB power cables have rx/tx wires connected to the ground. This does not allow GPS to communicate with MPU. Be sure to have the USB power cable with just + and - wires...

Hello, nice project. I thinking of using a BLE HC06 Module to connect to the Smartphone in order to ommit the GPS. A simple App could periodically update the position via Bluetooth. What do you think?

Hi, when I start driving I have just to "turn the key" to ignite the engine and go on. Car instruments, including this HUD, as well start working after that single, usual, popular operation. Bluetooth? Wifi? Login? Password? Pairing? Phone battery lasting? More cabling? Keep it simple. :-)

I finally finished my variant of your project. It uses a MAX7219 LED driver and a ATtiny1614 microprocessor. Build is at https://www.hackster.io/john-bradnam/car-windscreen-hud-e10cbd. Many thanks for a great project. 👍👍👍

Shouldn't the display show a mirror image like in the picture in the description section shows?

OK, I see now - you have transposed segments b&c and e&f from the 4511 ics - very clever 😃

Yes, it does. The picture shows a similar HUD as mine. Mine, the one in this project, got red and a bit smaller numbers, a compass, a led... :-)

Hello, i have a question. It must be USB B female, in this project? I can't find it, to afford it.

Hi, the USB B female I used let you easily connect the HUD to the car lighter (and an adapter 12V to 5V) by the way of a simple USB printer cable. It is just for the 5Vcc power supply.

And how u connect it to the car?

From today it is available a V2 (version two) of the software that together with two wires and one resistor you will have altitude information on the display as thousand of meters (i.e. 0.89 = 890m, or 2.45 = 2450m), just press one more time the S/H button! Read instructions above, look at the pictures for requested mods, download the new code provided and enjoy!

After a year of "continued" work inside my car I can say this circuit works very well and without problems! I am proud of it, I like it!

Hi, I made a new version V2.2 to show full altitude value up to 999m (more altitude as thousand of meters i.e. 2.40 = 2400m), and an automatic brightness variation of the display by the way of a LDR photoresistor. Have a look at the information and the pictures above. The new V2.2 sketch is also available for downloading. First step is to pass to V2, than to V2.2 (V2.1 does not exists)... :-)
