[To read Part I of this article, click]As you have seen from Part I, I have used flyback transformer in the circuit to light up a fluorescent bulb using 9V battery. Actually, I want to keep the whole circuit as simple and constructable as possible, where I want to remove some components that are rare, difficult to find such as flyback transformer and ferrite rods. As CRT tv and pc are obsolete nowadays, flyback transformer gets even rare and more expensive. Therefore I set a rule when designing .......

This is a very simple high voltage power supply circuit for laser device. It is low cost circuit and very easy to built. This power supply can be built with common parts, most of which you probably already have in your junk box. The secret of this circuit is the transformer used.It is a common 9V 1A transformer unit, connected backwards for step up. Please note that some peopl.......

HF Bands QRP RF Linear Amplifier based power transistor 2N5590. This is a rather unusual QRP power RF amplifier design, with a wide frequency response; within three dB's from 300KHz to 30MHz. Overall gain is in the region of 16dB and the final output power may be well over four watts. The wide bandwidth is a result of the construction of the RF transformers, T1 a.......

Some time ago digging the web for information on The Radio Club of Hartford, I came across this article in QST magazine (September issue, 1921). In a nutshell, it is about a QRP contest as it should be - -Do More With Less- and then measure how big this -More- is and how much spare -Less- were used.I read this article briefly: something about some kind of reward, some competitions, the names - not very exciting at first sight, but one remarkable thing caught my attention - The Winner, transmitte.......

The SN6505 is a low-noise, low-EMI push-pull transformer driver, specifically designed for small form factor, isolated power supplies. It drives low-profile, center-tapped transformers from a 2. 25 V to 5 V DC power supply. Ultra-low noise and EMI are achieved by slew rate control of the output switch. . .
