Arduino Glasses a HMD for Multimeter

I'm really feeling pissed off, when I see people using my designs and try to sell them as their idea.

This guy makes a nearly 100% copy of my Data Glass and only after I send him an email he added "inspired by Alain^s Projects". just inspired, really ???????

I think that's not the way open source should work. If you use the work of someone else, the minimum is to mention this person and set his website link in the description.

The only thing which calms me down, is that it is still my invention and other people will know it.

Hi, the lens is still the problem, because it is not easy to find.

I think, I found a good alternative. A small Fresnel lens. Easy to find, cheap and you can cut it with a pair of scissors.

Hopefully I will find the time to test it.

The focal length is about 110mm, with should be fine.

The new displays just arrived. Will build a smaller version.

I think I will start a new project for this.

Thinks to do:

• Finishing the Software, to auto connect to a Owon Multimeter
• Adding a battery indicator in the display. The BLE module has this feature.
• Building different reflectors with tint and mirror foils, to make the glasses work in a bright area,
• Reducing the weight and redesigning the enclosure.
• Testing with a smaller 0.49 inch display.
• Creating a technical Data sheet

Finally, all fits together.
Now a nice video of it, a full description and I'm done.

I needed to change the LiPo batteries. I use now a smaller, 280mA, instead of the 330mA. For this I had to change the resistor in the charger circuit. It's 3k smd part. I soldered a normal resistor with the value of 5.6k in place to reduce the charging current to 200mA.

Until now, I heated the reflection screen and bent it to 45 degrees. To make the construction easier I printed a new holder. In the picture, you can see the difference

I finally start handling the 123Design software and my 3d Printer.
I was totally focused on my cardboard design enclosure, but at the end, I had to redesign the glasses due 3d print problems. Now you can adjust the reflection screen, to get the best view.In the next few days I'll test the electronic with the new LiPo, but I'm still waiting for the lenses.

I finally printed out the covers for the enclosure. The mirror and the lens are mounted with all the electronics. All fits in, and it works great. This one has a lens with a focal point of 100mm.

All in. The controller, bluetooth, display, charger and the LiPo Batterie.

I just bought me a 3d Printer, and this is the first enclosure for my Dataglasses.
