Basic ElectronicsEasy Project Power Supply For Raspberry Pi & Beaglebone Using a Buck switching power converter makes powering all the different parts of your project a breeze. Do you need 12V for a display and 5V for your Raspberry Pi and Arduinos but you don't want multiple supplies plugged into the wall? One of these high powered converters could be the solution to your problem. More... Long Time Delays With A 555 Chip Getting Started With Electronics Review Power Dissipated By Resistor: How To Blow Up A Circuit 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 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... Transistor Touch Switch Simple Science Project 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... Science Projects For Kids First Electric Circuit 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...
