Summary
- Victor Poughon has made a replica of the sun using a home-made lens system with a bank of LEDs attached to a sheet of inkjet printer film.
- The lens was manufactured and polished by JLC and the custom PCBs were used to mount the LEDs on.
- The artificial sun is collimated to give a sun-like effect of coming from a great distance, although it is not as bright as the real thing.
- This is not the first artificial sun to have been made, with a previous version having been featured in November 2020 on the Hackaday website.
- Making an exact copy of the sun is a very exact project, but the results are impressive and it is relatively easy to do at home.
