Power Dissipated By Resistor: How To Blow Up A Circuit

A resistor burning with smoke

When you pass a current through a resistor it gets hot. The hotter it gets the more it can adversely affect the circuit that it's a part of. If it gets too hot then it can burst into flames before eventually failing completely. If this happens then it can have catastrophic consequences so it's a good idea to understand why components get hot and design circuits that don't overload the components used. I set about to destroy a resistor and demonstrate what happens when you dissipate too much power in a component. And I wanted to blow something up. More...

Darlington Transistor Touch Switch Simple Science Project

Components of Darlington transistor touch switch on breadboard

Here is a simple two transistor darlington transistor touch switch that you can build easily on a solderless breadboard. This build follows on from the single transistor touch switch project to significantly increase the sensitivity of the touch sensor. More...

Science Projects For Kids First Electric Circuit

Simple science project Light mouth scarecrow

How to do a simple science project with your kids. I was clearing out the loft the other day when I came across an experiment in electricity that I did with my daughter when she was nine years old.

It's a very simple electric circuit but we managed to combine the fun of learning about electricity with the fun of making a work of art. I can't believe that we kept it all these years but I thought that you might like to see it before it gets thrown out.

It's very simple to make so you can easily try it out on your kids too. More...

What Does A Resistor Do?

Resistor collection examples Resistors are the most basic building block of any electronic circuit. Luckily they are not difficult to understand and work with once you understand a few simple things. Resistance is measured in Ohms using the greek symbol called Omega Ω More...

I have gone through all of the material in this product to highlight both the bad and the good points. Overall it is a good beginners introduction to the how and why of electronics. Find out how this information can help you get the most from your electronic project building More...

How To Build An Astable Multivibrator Circuit Without Solder

One of the first electronic circuits I ever built was an astable multivibrator. It's a very simple yet reliable method of flashing a couple of LED's that you can build on a solderless breadboard in no time. Follow these simple instructions and experience the thrill of creating an electronic device and watching it do it's job. More...

A Power Off Delay For Computer Shutdown

Long delay circuit Cheap microcomputer boards like the Raspberry Pi and the Beaglebone are finding applications in many places. They bring breathtaking computer power to seemingly simplistic tasks opening up a world of possibilities. But they are microcomputers and you can't simply switch them off without performing an orderly shutdown. If you do you risk corrupting the file system and rendering the device unusable. More...

Transistor Touch Switch Simple Science Project

Components of single transistor touch switch on breadboard

Here is a simple one transistor touch switch that you can build easily on a solderless breadboard. Learn how to build a circuit that turns on an LED lamp simply by placing your finger across two wires.

This project illustrates how you can use a transistor as a solid state switch. No moving parts. Exept for your finger of course. More...

Long Time Delays With A 555 Chip

555 circuit I've been looking for a simple, low power, method to generate long time delays so that I can power up a datalogger at regular intervals to take measurements then shut it off again to save battery. I found that the humble 555 timer integrated circuit is more than up for this challenge. More...

Electronic Engineering Construction Kits For Kids And Parents

Educational electronics construction kits make excellent gifts for children. The kids won't realise that they are learning stuff because they will be too busy building diy projects and clicking together the experiments. This is one of the few kids 'toys' that encourages you to build things that really work and make it fun. More...
