This is a simple two digit counter using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart. It can be applied to, for example, counting products, counting people into the library, and more. The working principle As circuit in Figure 1. The IC1, IC2-CD4026 4026 […]
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.

This is simple circuit that we makes in hobby time or toys for my son but really uses. It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock. We use a IC-4011 CMOS only one and a few components also can generate pulsating tone like a general clock. […]
The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can assemble on a breadboard right […]
We use a simple oscillator circuit in very many projects. I like to use a inverter logic gate since it is easy and cheap. But we do not use it directly. Mostly I use IC4011 nand gates since includes for separate four positive logic nand gate on a single silicon chip. Enough for general use […]
Now I am Electronic projects circuits blogger. It is hard work and dedicated time. We certainly need an income families. Many years ago, I had main revenue from adsense. Now the sponsor is ads banner And a commission from amazon I am so thankful all my friends a lot. Some friends wanted me to sell […]
This circuit calls more Free Running Multivibrator work resemble Flip Flop. Which encourage itself repeatedly. The Q1 and Q2 be Transistor PNP be usable general (2N3906,2N2907, etc.) The R1 and R2 limit current that flow through LED the bilateral. If enhance the value C1 and C2 the rate something Flasher slow down. Request friends have […]
Today I want to show you a 220 volts power inverter circuit. Which it is easy and small size. Because use NE555 and MOSFET as main. This circuit I experiment it work well,When use source is 12V battery will have output of 100 watts. The principle of circuit. I think many people does not like […]
