Simple Solar Circuits Simple Solar Circuits: How to get started adding solar power to your small electronics projects. Use the sun to power small solar and battery powered night lights, garden lights, and decorations for halloween. The first part of a solar circuit is… a device for collecting sunlight. To keep things simple, we’re using a single nicely made small solar panel for all of these circuits. [Before we move onto our first examples, a word of caution: These are small simple circuits. Direct Drive: The most obvious way to use power from a solar panel is to connect your load directly to the output leads of the solar panel. Here are a couple of examples of this in practice: On the left, we’ve hooked up one of our little solar panels directly to a small motor taken from an old CD player. Interruption-resistant direct drive: The “direct drive” circuits work well for their design function, but are rather basic. Instead of adding a single supercapacitor, you might notice that we’ve actually added two.

Hobby Engineering Home Page Understanding Schematics You can see that there are various bits represented by symbols, all connected in various ways. Let’s look at some of the big picture concepts: Left to Right: The first thing to notice is that you read the schematic left-to-right: the input on the left feeds the signal through parts and pathways in the middle to an output on the right. This left-to-right convention is not universal, but it is probably the most common layout for a schematic. Each symbol shows a part number and a part value or type. Connections: The connections between components are shown by lines. Figure 1.2: Various Ways of Depicting Connected Lines In the first example on the left, a dot shows interconnecting lines. Inputs and Outputs For stompbox designs, you almost always have an input and an output. So when you look at a schematic like this, you are dealing with a sort of shorthand that the schematic author used. Figure 2.1: Shorthand Depiction of Inputs and Outputs Figure 2.2: Mapping Shorthand to the Real World Power

Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. To turn a switch on or off, just click on it. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Standalone (offline) versions. Index of Circuit Examples. More applets. Javascript version. Report a problem/feature request Huge thanks to Iain Sharp for the Javascript port. java@falstad.com

Control real world devices with your PC Parts list: Picaxe 08M chip available from many sources including Rev Ed (UK), PH Anderson (USA) and Microzed (Australia) Protoboard, servo, microswitch, 9V battery, 4xAA batteries and holder, tag strip, 10k resistor, 22k resistor, 33uF 16V capacitor, 0.1uF capacitor, 7805L low power 5V regulator, 10k pot, wires (solid core telephone/data wire eg Cat5/6), 6V lightbulb, D9 female socket and cover, 2 metres of 3 (or 4) core data wire, battery clips The above companies also sell USB to serial devices which are useful for laptops which don't have a serial port. It is worth noting that some USB to serial devices don't work as well as others and it is worth getting one from one of the above suppliers as they have been tested for use with picaxe chips.

10 Best Electronics Suppliers First off, I would like to give notice to Electronics Projects for Dummies for most of this info. I wanted to make a site with many of the best sites to buy Electrical Parts, because it can sometimes be a strenuous activity. I have 10 here, because if you can't find something on one online store, you might be able to find it on the next. Reynolds ElectronicsReynolds Electronics is a good supplier of remote control components, micro controllers, and robot kits and parts. One feature that stands out on Reynolds Web site is the clear and helpful project/circuit tutorials. Hobby EngineeringHobby Engineering is a sit slanted towards the hobbyist. All ElectronicsAll Electronics has an incredible selection of many of the useful items you would use to build your project. BG MicroBG Micro is a cool site for rare and pretty neat gadgets as well as a nice selection of alot of the items one will need for a weekend project. Jameco ElectronicsJameco has a very nice site catalog.

Free electronics projects and circuit diagrams (schematics) for hobbyists. Build your own electronic gadgets Makey Makey | Buy Direct (Official Site) How to build electronic devices on your own Building electrical devices is probably the most inexpensive engineering you can do because most electronic components are very cheap, like less than $1. How to actually build devices on your own isn't taught enough in engineering courses, so here's a quick summary of how to get started making devices like I have on my site. In this page, I kind of assume you're an engineer/scientist of some sort (or studying to be one) and that you've already had a few electrical engineering classes. If you don't know any electrical engineering, you'll obviously need to learn the basics before you can start inventing. , which teaches you theory and practical knowledge of components at the same time. First, get an idea To get an idea for something cool to make, it helps to go to online stores for electronic components (Jameco.com is a good one) and look at the components they have. Also, I really recommend getting a microcontroller, like the Arduino. Buy parts Here are a few typical parts that I use a lot:
