DIY Laser Light Show Is Sure To Please


[Pete] had some spare time on his hands over his spring break, and he was itching to build something. He settled on a laser light show since, after all it was spring break, and what says “Party” better than a laser light show?

He glued three hobby mirrors to three small motors, mounting the motor assemblies on the lid of a wooden cigar box he bought for next to nothing. When the laser is pointed at the mirrors, they reflect the beam off one another, and finally against a projection surface, creating interesting shapes and motion. He programmed an Atmega328 to control the laser light show when in automatic mode, and added 4 pots to control the mirrors’ spin rate when set in manual mode.

The visuals are pretty cool, as you can see in the videos below. We love the laser light show concept, and [Pete] definitely gets extra points for his cigar-box casing as well.

Follow-up: Radio-controlled LED Light Show


[Alan] shared an update with us regarding a project he has been working on for some time, radio-controlled LED light strips destined for use by the Travelling Light Circus. If you are not familiar with the project or need a quick refresher, you can read our post about it here.

He recently met up with the guys from TLC to finish things up and was happily surprised that they did not want to mount his lights on the performers, as was originally planned. He would have had to make a few modifications if that was the case, but instead, they planned on attaching them to bicycle wheels. The light strips were mounted inside translucent plastic tubes that fan out from the center of the wheels, where the battery and radio equipment is located. The wheels were mounted on aluminum poles, allowing the performers to create a visually stunning show, just by spinning the pole.

Check out the pair of videos we have embedded below, the project came together quite nicely.

Radio-controlled LED Light Show


[Alan] was commissioned to make some wearable, radio-controlled LED strips for the Travelling Light Circus. It has taken some time, but he has recently finished some prototypes, and thought it was a good time to do a writeup on the project. The system is managed by a single controller unit, which communicates with any number of LED driver units, each controlling 4 HL1606 LED strips. The light displays are synchronized across all of the LED driver units via a 2.4 GHz radio, with each driver falling into synch almost immediately after being powered on. While some might be turned off to the fact that he uses Arduino Pro Minis to control the LEDs, this is far from a simple project.

[Alan’s] blog contains several posts about this project, with everything documented in detail. He spends quite a bit of time talking about the project’s software, as well as hardware issues he ran into along the way.

His blog is a must read, but even more so, it is a must see. The lighting effects are mesmerizing, as there are a ton of different light patterns these units can generate, so be sure to check out the following video of the lights in action.
