Electronic kit

An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions and often a printed circuit board (PCB). People primarily purchase electronic kits to have fun and learn how things work. They were once popular as a means to reduce the cost of buying goods, but there is usually no cost saving in buying a kit today.

Some kits used to be quite complex devices such as color television sets, oscilloscopes, high-end audio amplifiers and even computers such as the Heathkit H-8, and the LNW-80. Many of the early microprocessor computers where sold as either electronic kits or assembled and tested.

Heathkit sold millions of electronic kits during its 45-year history.

Today, building devices from scratch for hobbyists and beginners has fallen in popularity due to the emerging complexity of miniature electronics and embedded software. People still build custom devices and special-purpose electronics for professional and educational use, and as a hobby.

Also emerging is a trend to simplify the complexity by providing preprogrammed or modular kits and this is provided by many suppliers online often. The fun and thrill of making your own electronics has shifted in many cases from easy to comprehend application and analog devices to more sophisticated and digital devices.

Examples

• The Altair 8800, (the first home computer), was also sold as a kit, as were the Sinclair ZX80, Sinclair ZX81 and Acorn Atom computers.
• Many S100 bus system cards were sold only as kits.
• Building a Robot kit, most often with a micro controller inside, is now in fashion.
