An LED based LightStim is a device used for rejuvenating facial skin by stimulating cell growth. Normally, RED LED is used in these devices since red light have been found […]
Mini Projects
When a few of electronic components are assembled together by following a simple schematic diagram, it constitutes an mini electronic circuit project.
Today the world around us is heavily knitted with all sorts of electronic systems, gadgets and devices, and all these systems are fundamentally built under a certain project name. This has inspired many youths and students to pursue electronics by building their own hobby projects in their leisure time. Consequently interest simply keeps growing and we see these budding hobbyists ultimately growing into full fledged engineers.
The following page shows a comprehensive list of diverse electronic projects and circuits which are simple to build using minimum electronic components such transistors, resistors, capacitors and some easily available ICs like IC 555, IC 741, IC LM324 etc. These mini projects are specially designed keeping the new hobbyists in view and so ensure that the circuits can be built by all newcomers and newbies in the field of electronics, either for for fun and for learning the concepts.
