Summary of Smart Glasses(Under $10!!!)
Summary: This tutorial shows how to build inexpensive smart glasses (under $10) using an Arduino (Pro Mini or Nano), HC-05/HC-06 Bluetooth module, OLED display, Li-Po battery with a power bank booster, lens, mirror, and 3D-printed frame. It includes wiring, 3D-printed cover design, programming steps, app pairing (Retro Watch), and assembly of optics and electronics to create a wearable display.
Parts used in the Smart Glasses:
- OLED Display
- HC-05 or HC-06 Bluetooth Module
- Power bank Module
- 10K Preset
- Slide Switch
- Li-Po Battery 3.7V
- Arduino Pro Mini or Arduino Nano
- Mirror
- 100 mm Focal Lens
- Transparent Glass
- CP2102 USB 2.0 to TTL UART Serial convertor Module (for Pro Mini programming)
- 3D printed outer cover/frame
Hi There!
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!
Supplies
1) OLED Display($2.64)
2)HC-05 or HC-06 Bluetooth Module($2.84)
3)Power bank Module($0.39)
4)10K Preset($0.12)
5)Slide Switch($0.27)
6)Li-Po Battery 3.7V($1.35)
7)Arduino Pro Mini($2.71)/ Arduino Nano($2.92)
8)Mirror
9)100 mm Focal Lens
10)Transparent Glass
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!

- What components are needed to build the smart glasses?
The article lists an OLED display, HC-05/HC-06 Bluetooth module, power bank module, 10K preset, slide switch, 3.7V Li-Po battery, Arduino Pro Mini or Nano, mirror, 100 mm focal lens, transparent glass, and a 3D-printed cover. - Can I use an Arduino Nano instead of a Pro Mini?
Yes, you can use an Arduino Nano; if using a Pro Mini you need a CP2102 USB to TTL module to upload code. - How do I power the device?
The Li-Po battery connects through a slide switch to the power bank module, which supplies the Arduino and other components. - How do I connect the HC-05/HC-06 to the Arduino?
Connect HC-05/06 VCC to Arduino 5V, GND to Arduino GND, TX to Arduino RX, and RX to Arduino TX. - How is the OLED display wired to the Arduino?
OLED VCC to Arduino 5V/3.3V, GND to GND, SDL to A4, and SCL to A5. - Where can I get the code and app needed?
The article provides a link labeled Code and App Link for the Arduino code and the Retro Watch app. - How do I pair and use the app with the glasses?
Pair the HC-05/06 with your phone, open the Retro Watch app, go to Watch Control, connect Bluetooth, and select the desired watch clock style like Simple Digital. - Do I need to 3D print parts for the outer cover?
Yes, the article advises printing the provided shapes according to your frame measurements for the outer cover. - How are the mirror and lens arranged?
Cut a mirror to size, buy a 100 mm focal lens and a small rectangular transparent glass, and arrange them as shown in the assembly images. - Is there a charging access point after assembly?
Yes, leave a hole in the cover for the USB port of the power bank module to charge the Li-Po battery.
