As I am looking into a couple electronics projects I have turned up a handful of fantastic resources on the web. Here they are in no particular order.
- Jameco – Broad selection of electronic supplies. Good service, includes pictures, great prices. These guys are my current favorite.
Digi-Key – Has some stuff Jameco doesn’t. Prices are a bit higher in general, but good service. No pictures. Poorly organized site.
- Circuit Schematic Symbols – Good list. Alphabetized by component.
- Circuit Symbols of Electronic Components – Fairly complete reference grouped by type.
- LED center – Fantastic information on LED products and using LEDs in your project. A great site with none of the garbage. Home of the LED calculator and the LED series/parallel array wizard which will calculate the proper resistor to use in your LED application.
- The Hardware Book – A great reference for cable and adapter pinouts. Some common, most hard to find.
- Play-Hookey – Fantastic, step-by-step instructions on a logical series of electronics experiments. Includes great information and instructionals on logic, electricity, analog circuits, and even optics. This site is definitely a great starting point!
- Bowden’s Hobby Circuit – A wide variety of projects. Great schematics, nice explainations, but not much for step-by-step.
