circuit, the circuit uses CMOS] Arts and manufacture, feet black soft cream package. SH-12:/chip with internal voltage standard device, so little need for external power regulator road, playing only a buck current limiting resistor R, it can, so that the outer circuit is simplified. It contains a chip oscillator source, Ding tune I just external electrical device RP, can change the Quad Lantern Fl - El Happy Valley velocity (flash frequency cho 1 to change within 200Hz). RI Available W} Ij synthetic carbon buck a locator .VIl-VT4 can state M [1k1 {10-8 type Guo Feng and other small items unidirectional thyristor, each color Chan Gong, Shen should IOOW less.
