The four main steps in coming up with a DIY AR headset are, creating what is referred to as an enclosure, doing some coding, ensuring the electronics are assembled, and then finally, combining everything together.
The materials that are basic for use for the augmented reality glasses are relatively cheap and you can easily find them online. Arduino Pro Mini 3.3v; stationary push button switch; 0.49 inch OLED Display; 5V mini USB 1 A battery – lithium charger module; Gesture sensor APDS-9960; lithium battery 3.7v; mini spy camera; and Bluetooth module HC-06. The tools which will do the job for you include soldering iron; 3D-printer; to create rectangular holes, a small Dremel will come in handy; Superglue; and a hot glue gun.
Other things that might come in handy when you are creating this AR headset might include, rare magnets, PLA filament, mirror, thin gauge wire, lens, resistors, solder, and wire strippers. According to research, it turns out that the eye is only able to focus on a virtual image which is 25 cm away from it.
When coming up with the headset, it is important to remember that, the image which is supposed to be created has to be a virtual one and thus, it is important you make sure that, its distance has to be greater than 25, and that, virtual images tend to have negative values. And it is also important you remember that people have different eyes, with some not being able to focus closer the way others do.
You can add as many things as you wish on your AR headset depending on your preferences. At the end of the day, you will be able to be technologically savvy with maybe a camera and a clock in your field of view when doing a task.
