Arduino Data Glasses For My Multimeter

Video of the working device Trying to build a cheap Arduino Data Glasses for everybody. Why? I just wanted one. It's working, and now it can even help to avoid accidents. From the first idea to the working prototype, it took 4 Month The challenge was, that It should be constructed out of common materials that can be found easily. The project is more about how to build the optical system for this HMD. One thing is clear, you can not just place a screen in front of your eyes, because it will not be possible for them to focus it. In the logs you can see from the first tests to what I have now. The optical design was the most difficult part, but I think I found a solution for this. The costs of the prototype amounted to +-70Euros. And now I have a Head-Up Display For Hight Voltage
