All circuits come with a component list and a connection diagram, schematic, or build instruction. So you can just start building right away.
If you have any questions about the circuits, just ask in the comment section of the circuit you're curious about.
Blinking LED Circuit with Schematics and Explanation
The blinking LED circuit is like the electronics version of the “Hello World”-program. It’s a simple electronic circuit that gives you a visual cue if it works. It was the first circuit I ever built, and it felt GREAT! The goal is to make a Light Emitting Diode (LED) blink.
Portable USB Charger Circuit
Build this portable USB charger circuit, and you’ll always have access to a charger. Imagine a beautiful summer day. You’re on your way to meet friends for a picnic in the park. But, the park is huge and full of people. Since you don’t know where exactly your friends are, you pick up your phone […]
Portable USB Charger Components And Tools
These are the components you need for building the portable USB charger circuit. These are all pretty standard components, so you can probably get these at your local electronics supplier if you have one.
Blinking Christmas Lights
Christmas is coming up, so why not set aside an hour or two to build this blinking Christmas lights circuit? This circuit is easy to build and it’s something you can put to use right away. I built this and hung it in the window, something my girlfriend loved! The blinking part of the circuit […]
The Simplest Power Supply Circuit
This power supply circuit is easy to build and cheap. And it requires only 5 components. I have built many circuits in my life, but this is actually the first time I’ve built a power supply circuit from scratch. The final project I wanted to build was a wall adapter with a USB socket to […]
