How to Build a Fake Sun That Looks Unbelievably Realistic

All you have to do is build yourself an artificial sun. That sounds wild, but it’s actually neither too difficult nor too expensive — this 24-minute tutorial by DIY Perks will teach you exactly how it can be done. Sunlight has unique qualities that ordinary artificial lighting can’t reproduce. For example, the distance of the Sun to Earth causes the light rays to be essentially parallel by the time they reach us, which results in things like shadows that don’t change in size depending on distance.

This property of sunlight can be recreated using a lens that takes an artificial light source and makes the light rays parallel. What you’ll need for this artificial sun build is a parabolic reflector — you may be able to find a cheap or free one by repurposing a satellite dish (like the kind you’ll find on the side or top of houses).

I use only the best silicone wire. This wire has been tested to handle 5A. It is super flexible and burn resistant. A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical overstress may occur to the laser diodes as the operation voltage varies from device to device and additionally depends on the case temperature. Furthermore, please note that at different temperatures the output power of the laser diode will change. Cheap Dual Mirror Laser Projector. [Stanley] wanted to make a laser projector but all he could find online were one’s using expensive galvanometer scanners.

So instead he came up with his own solution that is to be admired for its simplicity and its adaptation of what he could find. At its heart is an Arduino Uno and an Adafruit Motor Shield v2. The green laser is turned on and off by the Arduino through a transistor. But the part that makes this really a fun machine to watch at work are the two stepper motors and two mirrors that reflect the laser in the X and Y directions. The mirrors are rectangles cut from a hard disk platter, which if you’ve ever seen one, is very reflective. He’s even written a Windows application (in C#) for remotely controlling the projector through bluetooth. As for the expensive galvanometer scanners we mentioned above, check out this impressive laser projector that uses them.

How Lasers Actually Work. Lasers are optical amplifiers, optical oscillators, and in a way, the most sophisticated light source ever invented.

How Lasers Actually Work

Not only are lasers extremely useful, but they are also champions of magnitude: While different laser types cover the electromagnetic spectrum from radiation (<10 nm) over the visible spectrum to far infrared light (699 μm), their individual output band can be as narrow as a few µHz. Their high temporal and spatial coherence lets them cover hundreds of meters in a tight beam of lowest divergence as a perfectly sinusoidal, electromagnetic wave. Some lasers reach peak power outputs of several exawatts, while their beams can be focused down to the smallest spot sizes in the hundreds and even tens of nanometers. Laser is the acronym for Light Amplification by Stimulated Emission Of Radiation, which suggests that it makes use of a phenomenon called stimulated emission, but well, how exactly do they do that? It’s time to look the laser in the eye (Disclaimer: don’t!). Pump it.
