CD4027 datasheet of Dual J-K Flip-Flop
When we want to use flip-flops with CMOS. Often we meet CD4027. It is dual J-K flip-flops that are monolithic complementary MOS integrated circuits. We have seen many circuits that use them. Of course, making a great circuit we should understand detail of any parts( basic enough). Slow down! If you are beginner. You should … Read more
Simple flash slave trigger circuit
This is a simplest slave flash trigger circuit. It will help the slave flash immediately works almost simultaneously with the main flash. This circuit better than others circuits because without the external power supply. Read more
