Woodworking is an activity that I enjoy very much. The secondary from the electronics. But I did not study directly. So View from youtube mainly. Wood cutting is very important. If it does not cut straight or 90 degrees. When assembly is a piece of work, a lot of problems. Cutting by hand, though, to […]
Everyone need the electronic projects that correctly works.
The collection electronic circuit to show you that not enough.
Because sometimes them may not works, so you lost times and too much money.
I need to see you happy with your projects.
Therefore, I will experiment build them to assure to you that It is really works. But this working must to use long times and a lot power. Please wait me.
Because we have more than 700 electronic projects. It may cause you difficult to find them.
I hope you will like them and come back to visit mysite again.

The past, we’ve used only a digital logic circuit by IC. But, in truth. We do not need any Ics, may use Switch or Diode or transistors connected as a logic circuit. Try to see Figure 1 which use switch and diode connected as AND and OR gate , To make us understand the meaning […]
In the previous circuit, we use JK-flip-flop in as RS-FF. We will use pin R and S of flip-flops, by stores data of pin J, K and CK(clock). The experiment about the touch switch just to use your finger to touch them only also can turns ON-OFF circuit, this switch type is widely popular. We […]
An electronics workbench desk is very necessary. I inherited from my father, are the old desk about the age for 40 year. I like it a lot and binding,it is still in good condition. But it has little to wide for me. (Compared to a typical computer) Figure 1 the my old desk from my […]
