[Hobby DIY Garage](https://www.dapj.net/)\ \ Amps-n-Volts a html Newsletter which later became Amps Volts eMag on Wordpress. It is now Hobby DIY Garage. Strictly Hobby, Gadgets and Craft with greater weight for electronics hobby. \ Practical Electronics Learning with DIY. Even though marked as hobby, many of these sites have professional grade electronic designs. This indicates Expertise in any domain can resonate to a peak, only when Enthusiasm, Commitment and Practical Experiments forge the book, college  or web learning into a Skill. \ \ EE Firms and Resources in the web.

Crystals, Thermistors, Varistors, Variable Passive RLC are also Passive Parts. This is a way of learning. You must be sound in building analog and logic circuits first. \\ This is the order of learning .. - Learn to use Batteries, LEDs, Wires, Switches, Soldering Iron and Resistors. - Build some projects with NPN and PNP transistors with capacitors. - Try some Toy Transmitters and Receivers using RF devices and Inductors. - Fix some power supplies like Transformers, Diodes, Regulators. - Configure small Analog Amplifiers and also Audio Amplifiers, 555 Timer. - Test out some LOGIC circuits with the 40xx Chips like 4093, 4028. - Start with some small PIC project or 80C51 Microcontroller. - Make a SOC with DSP and build a Robot Brain controlled Online.
