![]() - another EPE low cost starter project, safe battery operation. Use to "freeze" the motion of moving machines etc., this easy to build project is ideal for novices. Uses an oscillator and power transistor to deliver high-intensity pulses to a pair of external LEDs - no Xenon tube required! |

Practical Oscillator Designs - a major new series which is intensely practical, written specially for experimenters and hobbyists. Tried and tested circuits are "fleshed out" with component values, and the operation of a wide variety of oscillators is covered. Part One covers Hartley oscillators, and provides useful practical applications as DC-DC converters, metal detection and frequency generators, and variations. An absolutely essential feature on practical analogue electronics, great for hobbyists, not to be missed! |
