Photoluminescent stars on your bedroom wall or ceiling are quite cool, though the stationary shapes can ended up being boring. [Adi] felt this way, too. While doodling with a bright white light on some glow in the dark vinyl, it occurred to him that this might produce an fascinating display. He set about making GLO, the midnight message board as well as RSS display.
[Adi]’s light writer utilizes 12 UV LEDs on a linear axis powered by a stepper motor to compose RSS headlines, Twitter trends, or custom-made text on his wall. He discovers the sluggish fade of the text extremely soothing to autumn asleep by, as well as it’s simple to see why. The LED range imprints a section of a character including a 6×5 bit pattern. The 12 LEDs are split into two groups, so it can compose two lines at 45-50 characters each. [Adi] developed his own pixel font style for this project, as well as advises that only upper situation letter develops be used.
[Adi]’s review is rather admirable as well as comprehensive. In the circuit develop section, he advises that the LEDs should be extremely close to the vinyl for optimal results, however that they ought to protrude farther than the shift registers so the chips don’t rub the vinyl. Of program you might choose a lot more intense light sources, like laser. See it in action after the break.
