electronics

You only need to look around the room to see the influence that Electronics has on your life. It’s pretty hard to imagine an existence without modern electronics, almost everything we do during the day (including reading this website) is made easier and better thanks to the cool electronic devices that we pretty well take for granted.

Electronics as a hobby is something that has been around for decades, indeed some of the earlier advances in electronics where due to hobbyist and their experiments. Things like radio, television, computers and even robots have all been developed and perfected by hobbyists long before they became commercial devices.

You might think that in this modern age it’s pretty well impossible to build or develop something new in electronics – after all you really need to be a multi-billion dollar corporation with a research team and a high-tech manufacturing factory in order to do this right? Well actually that isn’t true at all! In fact today’s new generation of microcontrollers, inexpensive electronic parts and circuit boards assembled in China and Taiwan have ushered in a new era of electronics experimentation. Consequently you can now build things that we could only dream of just 10 years ago, even if you’re just a beginner.

So check out our easy to follow tutorials and detailed videos and get started on your electronics creation today. Even if you’re just a beginner you’ll be a young Tom Edison before you know it.

Welcome to the Workshop!

Soldering the Raspberry Pi Zero GPIO Connector

Here's a quick tip for soldering a 40-pin GPIO connector to a Raspberry Pi Zero or Zero W. While it's not a difficult solder job the problem many folks have is getting everything aligned and held together while you do the soldering.

In this article I'll show you a trick I use to make this job a lot easier. And unlike some other methods this one won't sacrifice a solderless breadboard

So warm up the soldering iron and get ready to add a GPIO header to your Pi Zero!

Don't get Zapped by Static Electricity!

It's hard to say anything nice about static electricity. It causes things to stick to your socks, makes it difficult to comb your hair and can give you a nasty zap when you touch a doorknob after walking across a carpet!

Even worse, static electricity is a deadly enemy for electronic components. A static shock can completely destroy or severely degrade fragile semiconductor devices. In this article we'll examine what you can do to prevent that from happening to your precious components and circuit boards.
