Normally when we solder several electronics projects, always difficult I see on internet people like to use a helping hand tool as Figure 1 below it bestseller on amazon. If I need to use it now, but will buy at amazon must to wait for 3 days or I don’t like to looking for it […]
We like to collecting the electronic circuits with PCB layout as ideal of building the Easy electronic projects, under different scenarios.
The projects are mostly old but still works great. Suitable for use or to study.
Now, We have a lot of articles(over 600 circuits). So, difficult for find the circuit as you need. It is a pity if you close this site without the great experience.Recent New Posts
Before Read this story please understand it is easy. So is not ideal for all user or expert or advance. I write it to protect my forget (I am old man). Today I was assigned by the housekeeper to add a power strips another one joint. Because, she organized a new kitchen. Reposition the new […]
This is a sound effect generator using small electronic components to generate since birds up to siren. With two IC-CMOS are main. This circuit can many loud sound in one. It is valuable for very educational, since the counter circuit, to convert digital signals to analog signals. Features of controlling frequency of Oscillator circuit using […]
This is simple intercom using transistors so easy to build and cheaper than ICs. They perfect for a small home, and to use basic or demonstration projects, from easy to find materials. It helped we can contact together simple in the house without have to walk a various room or shouting loudly, until may have […]
A electronic buzzer is simple. But useful well worth and the price is lower than 1$. By use just a 9-volts battery only. So without worrying about electrical leakage or electric shock from 220V to buzzer. Unless also has LED will glow. Show that the circuit the normal operation as well. The working of circuit. […]
After the I presented a model for many applications. Let’s see some toy circuits. This is an electronic dice circuits. Which looks like a real dice. We use only the press switch being thrown. Although this is the high-tech toys. Such as, Game PC, Tablet so expensive. But this projects an enchanting are: To start […]
The oscillator or the frequency generator, By most popular use NE555 or transistors or various gate. The output frequency setting depend on the resistance or capacitance As well as use the crystal control or frequency to the circuit. The frequency generator will see that has Designs commonly used in an electronic circuits, specifically the digital […]
