grabcad

A revised wand with a roomier handle and a threaded pommel for a sturdier seal and more space for electronic doohickeys has been added. Six modes are available in the LED wand controlled by a Cherry switch, which is also used to turn it on/off. In mode 0, the blue LED gradually increases to full brightness while the red dims. In mode 1, the red LED fades while the blue remains on at full brightness. In mode 2, the green LED fades while both blue and red remain on at full brightness. In mode 3, all three LEDs fade simultaneously. Mode 4 features a rapid ramping up and down of the LEDs with overlap, while in mode 5, the lights flash fast in sequence. A 9 volt battery powers the wand, which also includes a power switch, a keycap set, and an Arduino Pro Mini (5VDC) for the LED control.[1]
