This is circuit for dimmer a lamp or controll speed of a DC motor. I used to suggests these circuit by use principle most PWM (PWM Control Speed Motor 12V By TL494) form. But TL494 is not cheap and hard to buy we use NE555 beter very cheap and popular. This circuit have a lot […]
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
We is used to suggest a small integrated amplifier or the power amplifier with tone control circuit Were combined on the same PCB are 20watt Integrated Amplifier by TDA2005, but them is Mono. Today we see a 19 watts Stereo amplifier circuit using TA7240AP, ideal for small rooms Or use the car because the power […]
This is a two tone door buzzer, which is an electronic buzzer types,but them has melodic sound than the general electric bell. Which many people have seen the two tone bell sounds from other electronic journals. But they are circuit that made no who apply them, since Problems three reasons: 1.First, while do not press […]
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 […]
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 […]
