Introduction: Smart Glasses(Under $10!!!)
We all are familiar with Smart Glasses like the one named E.D.I.T.H. made by our beloved character Tony Stark which was later passed on to Peter Parker.
Today I am going to built one such smart glass that too under $10! They're not quite as subtle as the ones in film, they do have some impressive abilities.
So without wasting any time let's get started!
1) OLED Display($2.64)
2)HC-05 or HC-06 Bluetooth Module($2.84)
3)Power bank Module($0.39)
6)Li-Po Battery 3.7V($1.35)
7)Arduino Pro Mini($2.71)/ Arduino Nano($2.92)
9)100 mm Focal Lens
Step 1: Circuit Diagram and Connections
The above image shows all the connections for the Glasses...
- HC-05/06 -> VCC- 5V of Arduino
GND-GND of Arduino
TX- RX of Arduino
RX- TX of Arduino
2. OLED Display-> VCC-5V/3.3V of Arduino
GND-GND of Arduino
SDL- A4 of Arduino
SCL- A5 of Arduino
3.LiPo Battery-> +ve - Slide Switch & Slide Switch - +ve of Power bank Module
-ve - -ve of Power bank Module
4.Arduino -> Vin - 10k Preset
GND - -ve of Power Bank Module
5. Power Bank Module-> +ve - 10k Preset
Step 2: Outer Cover
As per the measurements of the frame of your Glass, print the above given shapes for the cover from a 3D Printer or a shop nearby.
Step 3: Program the Arduino & the App
If you are using an Arduino Nano, then skip this part... If you are a Pro Mini then use a 'CP2102 USB 2.0 to TTL UART Serial convertor Module' to upload the code to your board.
Link for the code and the app:-
Step 4: Arrangements
Now Arrangement all of your circuitries inside the cover and attach the Power Bank Module on the top cover. Make sure to have a hole for the USB Port that will be needed for charging the LiPo Battery.(as shown in the given image)
Step 5: Lens and Glass
Take a mirror and cut it into your desired dimensions.
Buy a 100mm Focal Lens and a small rectangular transparent glass.
Arrange them as shown in the images above...
Step 6: Attach With the Specs
Join the two parts together of the outer cover together and attach your specs as shown in the images...
Step 7: Connecting With Your Phone
Download the app from the link given before...
Pair your HC-05/06 with your phone.
Open the app named 'Retro Watch'.
After opening the app:-
Go to Watch Control Section> Connect your bluetooth module with your device(Connected will be displayed as shown in the above image)> in watch clock style, Select Style to Simple Digital (or the style you prefer).
Step 8: Finish!
And you are done!
Enjoy your Smart Glasses!!!
