1st "project" is 4 Esaki oscillators. The transistor is reversed biased. If you use a diode you won't stress out the transistor. #2 Astable multi vibrator. #6 Same as #2 just different look. #7 same as #6 and #2 just a different look and no need for 2 resistors because the extra LEDs compensate.

[@aramboodakian9554]

For those in the USA the 2N2222 is an equivalent transistor to the BC547 ( European). Wish there were titles if the circuit before each build and LED descriptions. Circuits are okay but nothing that spectacular.

[@indian.techsupport]

There are no european or american models, the 2n2222 is completely different from the bc547, but you can can use basically any npn transistor for these circuits.

[@aramboodakian9554]

You are right that they are not the exact same part. I should have used the words “good substitute” My point is that the designation “BC” is the European standard and “2N” designation is from the US standard : Joint Electron Device Engineering Council (JEDEC) The JEDEC part numbering scheme evolved in the 1960s in the United States. The JEDEC EIA-370 transistor device numbers usually start with 2N, indicating a three-terminal device. Dual-gate field-effect transistors are four-terminal devices, and begin with 3N. The prefix is followed by a two-, three- or four-digit number with no significance as to device properties, although early devices with low numbers tend to be germanium devices. For example, 2N3055 is a silicon n-p-n power transistor, 2N1301 is a p-n-p germanium switching transistor. A letter suffix, such as "A", is sometimes used to indicate a newer variant, but rarely gain groupings. JEDEC prefix table Prefix Type and usage 1N two-terminal device, such as diodes 2N three-terminal device, such as transistors or single-gate field-effect transistors 3N four-terminal device, such as dual-gate field-effect transistors. European Electronic Component Manufacturers Association (EECA) The European Electronic Component Manufacturers Association (EECA) uses a numbering scheme that was inherited from Pro Electron when it merged with EECA in 1983. This scheme begins with two letters: the first gives the semiconductor type (A for germanium, B for silicon, and C for materials like GaAs); the second letter denotes the intended use (A for diode, C for general-purpose transistor, etc.). A three-digit sequence number (or one letter and two digits, for industrial types) follows. With early devices this indicated the case type. Suffixes may be used, with a letter (e.g. "C" often means high hFE, such as in: BC549C[97]) or other codes may follow to show gain (e.g. BC327-25) or voltage rating (e.g. BUK854-800A[98]).

[@TECHIDEASCENTER]

[@kennmossman8701]

2n3904 is a better sub though has moderate gain BC547 does have very gain which can be critical the 2n2222 has relatively low gain

[@PeterEdin]

Did you need the transistor for the reed switch circuit. Just the switch, resistor and the LED would have worked.

[@TECHIDEASCENTER]

If there is no transistor, the reed switch will spark inside itself every time it is connected, which will cause corrosion and ultimately failure of the reed switch.

[@TECHIDEASCENTER]

But with this method, your reed switch will work without problems for years.

[@PeterEdin]

Thank you. I also noticed that you sometimes use the BC547 without using the base, is this you using the transistor as a diode?

[@TECHIDEASCENTER]

@@PeterEdin It is called reverse bias

Good morning teacher... how to build a circuit, for motor vehicles, input voltage 12V. Following electronic scheme: 5 LEDs will be used which, when powered, will light up alternately, one at a time, they will never light up all at once, that is, two, three, etc... and there will be a 6 Led that will remain on, with the circuit energized, constantly, while LEDs 1 to 5 remain off. When turning on any LED from 1 to 5, LED 6 must go out. How to build a circuit with this format?

So please, guide with minimum things order, because I not able to use those in future, without your help. The unit could be operated with (AC) 220 volt or (DC) 12 watts.

[@KarikhSergey]

Очень плохо, BC547 имеет Hfe~250-270. А для нормальной, долгосрочной работы светодиода 5мм достаточно тока в 20мА. Из этого следует что от питания в 4В резистор базы должен быть не 10К, а 50К. 4В/10к=0,00004А*250hfe=0,1А это очень много для светодиода. А вот 4В/50к=0,00008А*250hfe=0,02А это заебись!

[@indian.techsupport]

In this case thetransistor is only used to switch the led and the current is limited by a resistor, therefore tjis curcuit is safe, if the led would actually receive 100mA it would be instantly dead.

[@KarikhSergey]

@@indian.techsupport Не правда, судя по вашей схеме, у Вас один резистор является резистором базы, а второй подтягивает Базу на землю через геркон, тем самым закрывая его. Каким из этих резисторов вы ограничиваете ток коллектор-эмиттер? ))) Резистора в цепи коллектора у вас там нет. Следовательно всё гасится на транзисторе. И светодиод может выдержать ток в 100мА но очень не долго.

[@buffplums]

That’s the trouble with sharing ideas like these on KZbin so many bad and unsound principles or lack of them are shared. Ok it’s good for people to learn but take the first example it’s full of unsound ideas… I personally hate seeing LEDs wired in parallel without an individual current limiter resistor because no two leds have the same characteristics and one will inevitable conduct more than the other. Ok I get the use of an open base here to get that random effect of flashing but I wouldn’t use it much anywhere else… too unpredictable…. But hey what do I know … only about 40 years in the trade and then another 10 as a hobbyist before that

[@hoofbags]

I think the first project, unconnected base, is referred to as the reverse avalanche effect and only a minority of transistors will exhibit the effect and, as you say, it's undependable. Also, it usually only works at about 18-24 volts supply. I really liked the last project: it would be possible to build a chaser light display with that one. I thought the only circuit that would do this was using a 4017. The chaser would only work with three stages, works well on my solder less breadboard and has possibilities.
