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
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
SEE! TDA2030 audio amplifier circuit. To make many amplifier 10W to 120W. Mono or Stereo and OTL, OCL, BCL (Bridge amplifier) I love it Read more
This circuit is an automatic reverse polarity switch. If we apply DC voltage to any electronic circuits in the wrong polarity. It can be caused by too much current. You must waste time to reverse the new terminal. If your circuit is important, let’s build this project to your life will better. Automatic Reverse polarity … Read more
Good tool! The ultimate solution to the problem. Read more
