The AMAZING Corroscating Light Board !!

thingiverse

I came up with this gift idea for my teenage daughter, a mini handheld light board. Standard strip LEDs go along the entire diameter of a 220mm diameter piece of borosilicate glass (3mm thick, heat tempered - safety first). It's best to set up an adjustable voltage power supply to regulate brightness of the LEDs, which allows achieving the perfect glowing effect when writing on the glass with Neon washable marker pens. Note there is a dimmer module included here, which uses an Arduino Pro Mini controller, providing infinite possibilities. The 12V power supply is readily available with the mating connector integrated into the light board frame design. This light board is useful in many ways - as a toy, a family message board, or even a night light with a message! The Light Board pictured here was built using PLA Wood (Hatchbox), stained with wood stain and several coats of Shellac over that stain. Don't use Urethane; it won't harden since the wood stain doesn't fully absorb into the material. The frame is designed to accept a 12V power supply with a 2.1x5.5mm plug connector, like this one: https://www.amazon.com/Adapter-100-240V-Transformers-Switching-Adaptor/dp/B019Q3U72M/ref=sr_1_1?ie=UTF8&qid=1491435387&sr=8-1&keywords=12V+Power+Supply+Adapter+and+2.1mm+x+5.5mm+DC+Connector Power Controller components include: * 5-35V 3W LED Driver 700mA PWM dimming DC to DC buck * Arduino Pro Mini * Large momentary push button switch LEDs used: 30/M 3528 Patch, White Light Strip 1M If there is some interest, judged by views / comments here, I will post a more detailed Bill of Materials with links to items and assist makers in building their own.
