Hello Friends ! We've all heard of Holographic Heads-Up Displays (HUDs) for cars and they cost around 30-50 bucks. Well today I've got an idea and we will make our own Heads-Up Display for about 5 bucks !! Yes, you read correct 5 BUCKS only.

So, Let's make it

Step 1: Gather the Materials

Picture of Gather the Materials

We need very simple materials for this Project. I've provided a list below for the materials required -

Transparent CD case .........(X1)

Some basic tools are also required for this Project. The list is given below -

  1. Hot Glue Gun
  2. Super Glue
  3. Protractor

Cool idea, but beware of an important safety component of a HUD that you're missing here. Your display is not collimated. This means that when you look at the reflected image, you are focusing your eyes to the distance of the device (eg. 2-3 feet), not what is past it (eg. the road in front of you at 10+ meters), and therefore you effectively might as well be looking at the screen directly. A collimator lens makes sure only the light traveling straight (ie. focused at infinity) gets reflected back to your eyes. This can be done on a small scale with a plastic fresnel lens. Here's someone's DIY example of HUD collimation https://en.wikipedia.org/wiki/Collimator#Optical_collimators.

Where exactly is the "Hologram"?
I only see a reflection of a "Real" image.
Exactly! People misuse this word way to often. That and quantum
Don't forget about blockchain!
