1、制作霓虹灯闪光花样控制器：

常用的两种类型高压霓虹灯闪光花样控制器常因凸轮磨损、铜板磨损或电机损坏而不能正常工作，还因其为低速电机机械传动不能调速，限制了它的灵活性。图中所示的霓虹灯发光花样控制电路具有寿命长，逻辑功能多，成本低（只有机械控制的40 ），结构简单等优点。

此电路能控制1、2、3、4个字霓虹灯依次点亮，即“图案展开”；4、3两个字依次熄灭，即“图案收回”；在第一个字亮的基础上，第1、2、3、4个字依次独立点亮一次，然后从头循环。

2、电路原理：

IC5为时基集成电路组成脉冲振荡器，为IC1十进制计数/分配器提供时钟脉冲。IC1 10个输出Q0~Q9组成双四路输出电路，用来控制IC3、IC4四二端“与”门电路不同输入与门组合，使4路霓虹灯按次序闪亮发光。此电路所控制的4路霓虹灯发光状态中，至少有一字亮，避免了一片漆黑的不良后果。另外可根据需要，讲上述4路控制扩展成5路、6路或更多路。图中用灯（P1、P2、P3、P4）代表高压霓虹灯变压器。

-A production of neon flash pattern controller:

The commonly used two types of high-pressure neon flash pattern controller due to cam wear, copper, wear or motor damage, but not working properly, but also because of its low-speed motor mechanical transmission can not be governor, limiting its flexibility. The neon light-emitting pattern control circuit shown has the advantage of long life, the logic function, low cost (only 40　of the mechanical control), and a simple structure.

This circuit can control 1, 2, 3, 4 words to the neon lights were lit, and that "the pattern expand　4,3 word turn off, ie," the pattern of recovery "　in the first word of the brightest on the basis of a , 2,3,4 a word followed by independent light, and then scratch cycle.

2, the circuit schematic:

　 The IC5 time base integrated circuit composed of the pulse oscillator, the clock pulse for IC1 decimal count/distributor. IC1　10 outputs Q0 ~ Q9 is composed of a dual-quad output circuit used to control t
