This is the third of 13 toy boxes planned for my grand nieces and nephews. So far, all are unique and have their monogram on the front and some kind of fiber optic light show on the front. This toy box, completed for my niece Grace is made primarily of pine. (A fourth toybox is 40% complete and collecting dust on my work bench while I am working out of town.) The monogram is scroll saw cut from 3/16” thick douglas fir and the wreath is carved from mohagany and inset in the surface. The face of the box has 200 points of fiber optic light points lit by a 10 LED chaser circuit with multicolor LEDs sequenced to simulate a fireworks cascade. The chaser circuit is activated by a second circuit re-purposed from a security light. The fiber optics are run in channels in the back of the face boards and covered by a 3/16” panel. The electronics are housed in the bottom of the toybox and will run off a 9 volt battery, or a 9 volt transformer. The security light circuit activates the chaser circuit light show when it is sufficiently dark and detects motion, and continues for a short time after motion is no longer detected. I included a sliding tray with small “hidden” drawers on the bottom and a child sized “Jewel Stool” with embedded round glass bead “Jewels” inset with forstner bits and hot glued. For safety I drilled several 3/4” air holes in the back under the tray rail and under the handles on the sides and used a lid holder to keep little fingers from getting slammed by the lid.
For future projects I am looking at possibly using the Arduino micro computer as a programmable driver of LED’s, or other outputs. This would allow multiple input sensors that would run light shows, or sound effects.
