Tutorials on electronics for beginners, hobbyist, and experienced geeks. Electronics is a vast area that covers analog and digital systems. Codrey explains how to build your own analog circuits and transforming them into digital blocks.
There are certain applications that require only very low current and loose output voltage regulation. For such applications, a linear regulator made of discrete components is a quick and easy solution. For those who want […]
Bristlebot is a great easy way for kids to start to learn basic electronics. Bristlebot is perhaps the simplest form of a walking robot with a rigid bristle toothbrush body. It seems simple, a Bristlebot […]
Although there are many dedicated sensors and sensor modules to measure current, this post describes the more orthodox method using a shunt resistor! A shunt resistor is a power resistor with very low resistance especially […]
For today’s post, I thought it would be a good idea to see if I could create a reliable soft latching switch mechanism using a handful of electronic components lying around… First of all, note […]
Still, a google search for a commonly available temperature sensor to connect to a microcontroller quickly brings up the LM35. And, copy-paste of a little bit of clichéd code uploaded to the intended microcontroller makes […]
Today, let us have a quick look at the task of boosting dc voltages. It is perhaps worth noting that every other consumer electronic gadget on the market performs some form of voltage conversions imply […]
When designing a security system, often we need to add a siren circuitry with it. Fortunately, there are many analog and digital electronics ways to accomplish that chore. However, these days, we can also use […]
A current mirror is a circuit segment that functions to produce a copy of the current flowing into or out of an input terminal by replicating the current in an output terminal. In the analog […]
After getting a few vintage automotive solid state relays (SSRs) from a flea market thru a friend abroad, I decided to make a low-cost automotive solid state relay myself. So, this post covers the design […]
Get ready to make a high-resistance continuity tester pen that runs on a pair of common 1.5V AA batteries. This design is based on an idea from a Chinese website but with a few modifications. […]
