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": is an open source project and runs under GNU General Public License version 3.

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

By using the calculator you gave the link to and the google lens (f=4.5cm), is it correct that you had to place the display at ~5.5cm to get the correct focus? I would have infered from your 3D file but I see you haven't put it out yet.
I'd love to built me one of these. My thesis was pretty similar and the biggest pain is the focus(!!!), i.e. I feel your problem ;)

Very nice, I can see this being very very handy. I know the multimeter itself is not really part of the main objective of the project. But if/when you look into it, this TI reference design might be handy

Wow, Thank you for the information. When I looked for a Multimeter with Bluetooth, I could't find this one. I'll try to get one of these :)

Hey Alain, I just signed up because I noticed this new iteration of your smart glasses project. Your other project helped me a lot in doing something similar, but on top of that I found a part that you maybe missed in your research.

I can recommend you to look into a "beam splitter", like this guy is using in his glasses in this video. It's actually what Google also used in their Glass.

Good luck with your new project :)

Hi Tim,

Thanks for the info, I saw this video, but I still try to make it work with the more common material. Google glass has a slightly different beam splitter. It has a parabolic reflector at the end, so that the picture passes the mirror twice.

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..

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.
