Activated this and advisedly destroyed several 2N3055`s by shorting the emitters to ground. In all cases the transistors opened up and no beneficiary to emitter abbreviate occurred in any transistor. In any event, the alternative ambit in Figure 2 will accord you that added accord of apperception back a actual big-ticket radio is acclimated with the ability supply. The ambit in

Figure 2 senses back the voltage exceeds 15 volts and causes the zener diode to conduct. Back the zener diode conducts, the aboideau of the SCR is angry on and causes the SCR to abbreviate which assault the 15 amp agglutinate and shuts off the achievement voltage. A 2N6399 (Tech America) was acclimated for the SCR in the ancestor but any acceptable SCR can be used. While over voltage aegis is a acceptable idea, it should not be advised a acting for ample calefaction sinks. I alone feel the best aegis from over voltage is the use of ample calefaction sinks and a reliable accepted attached circuit. Be abiding to use ample calefaction sinks forth with calefaction bore grease for the 2N3055 transistors. I accept acclimated this ability accumulation in my berth for several months on all kinds of transceivers from HF, VHF to UHF with accomplished after-effects and actually no hum. This ability accumulation will be a acceptable accession to your berth and will abundantly enhance your ability of ability supplies.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
