“This is the simplest way of creating a hologram, where the light source and the screen are placed at an angle of 45 degrees.
This is another in my series of unusual DIY clocks, this time realized based on the holographic effect.It’s really very interesting to watch, and you get the impression that the numbers are floating in the air.
Otherwise, this is the simplest way of creating a hologram, where the light source and the screen are placed at an angle of 45 degrees. In case when we have a text or a numerical message, we need to know that the information of the light source should be a mirror of the original image which we should see on the screen.
For the light source I use a very simple to build matrix clock, which is actually a modified version of one of my previous projects entitled “Arduino Nano mini LED matrix clock”, where I modified the original code to get a mirrored image.
As I mentioned the clock is really simple to build, and consists of several components:
- Arduino nano microcontroller
- DS3231 Realtime clock module
- 8x32 Led matrix module
- and two buttons
