Safety Glasses With B.T. Display for Multimeter

A safety glasses with a bluetooth enabled head mounted oled Display, to diplay data from your measuring device right into your view field.

Similar projects worth following
Sometimes you work at places with a measuring device, like a Multimeter and it is dangerous to turn your head to look at the display of your device.
So here is the solution. A head mounted Bluetooth enabled remote display for your measuring device. It will display all the information right into your viewing field.
This one will work also in daylight environment and because not everybody wear glasses, this one is integrated straight into the safety glasses.
It will be based on my first "Data Glasses for Multimeter":

It will be an on-going development of my first Data HMD.

This working Data HMD can be found here Data Glasses for multimeter

And again, the optics will be the challange. This time I will try to make it work with a more common lens.

I'm not sure if I will create a PCB or just use finished modules. Let's start...

  • 1 × Adruino pro micro 8Mhz 3.3V
  • 1 × 0.49 inch Oled Display Controller 1306 I2C
  • 1 × Hm11 Bluetooth 4.0 BLE modul
  • 1 × Lipo charger circuit
  • 1 × 250mAh Battery
  • 1 × 3M Safety Glasses

    Today I made the first optic test with a cardboard construction. It's the mirrorless version.
    Works great and has definite potential.

  • 0.49 inch display ... online

    Today I found the time to connect the 0.49 inch, I2c display to the Arduino. I used the u8glib. The display is not in the list but this one works fine:

    U8GLIB_SSD1306_64X48 u8g(U8G_I2C_OPT_NONE)

    Now that the display is connected, I will play around with the U8Glib. The first Bitmap works:)

    I'm trying 2 head mounted display concepts. One works with a Lens with an focal length of 45mm and a reflective surface. The other one is a Lens with an focal length of 15mm and a direct view.

    Both are working fine with the first tests I've done.

    Here are the safety glasses from 3M, I just bought today and the first setup with the 45mm lens

  • First Parts

    The first parts are here. For the tests, that's all I will need.

    The A and O of this project is the Lens.
    I need to create a virtual image at a distance of min 25cm, so the eye can focus the screen.
    So the focal length and the magnification factor are very important.

    A google cardboard lens with a focal length of 45 mm will be the first lens for my test, even that the magnification factor could be a problem. So the calculations are one thing the other one is.... just do it :)

    To calculate the lens, I use this link

I saw the first development of your system and really think that's a think the people use in theier work !!  Go on!! 

Best regards from a guy doing the work with out your genius idea.. 

  Are you sure? yes | no

Thank you. The first one was like a kind of inspitation and it´s realy usefull. But it was the first version with a few hick hacks :). This time I will try a new aproach for the optics.
