Have you ever built a super cool Hi-Fi audio amplifier at home using simple components? If not here is the guide for you and I am pretty sure you will enjoy this one. This article tells about how to make a DIY Hi-Fi audio amplifier with output transistor protection circuit and 2-way speaker protection circuit. Let's

I saw someone discussing chargers a few days ago. Since I had nothing to do, I decided to show off my own DIY charger design! This is the circuit diagram when it was first designed. Later, during the specific debugging process, it was found that the MOS tube and inductor in the BUCK generated very high heat

Wireless power supply is a very attractive production topic. Many electronic magazines and forums have introductions to the production of wireless power supply circuits. Although these circuits have their own advantages, they all have a common shortcoming. First, the transmission efficiency is not ideal. Second, regar

introduction: There are many articles introducing the application of single-chip microcomputers, but there are few articles introducing the production of single-chip microcomputer development tools. Since single-chip microcomputers are a very practical course, if the traditional development model is adopted, it is n

I came up with it when I was bored, and successfully made a super-miniature receiver. It can be used as a Bluetooth headset, haha. It's just for fun. You can make one according to the circuit diagram for fun, but don't use it in the exam room! This micro receiver is very small, s
