In India when I went to bachelors engineering school, I remember they used the 555 as an educational tool. We built some basic circuits with it. Chances are, it will remain a great educational tool for a very long time to come.
The 555 timer, it’s a device that most electrical engineering students are familiar with because it is used in the educational setting to teach students some fundamentals of the concepts circuit analysis and of integrated circuits.
@@zoeherriot VERY old TV's. I remember at college back in 1982 we had 1 in amongst 19 others as a rack to fault find on. These Black and White TV's ranged from Just tag strips and Valves (A bit like the way the IC is in the video) to Hybrid Valve and Transistor and PCB's to just Transistor and PCB's. (As a side note, I remember TV17 was the same model as the one we had at home) The circuit diagram of the tag strip one, had another diagram which showed you the physical position of the components. It looked awful.
NE555 is probably a version of IC555 which uses a configuration of 3 5kOhm resistors internally (hence the name). This IC is used to generate time based logic, as you can see in the video.
@@predatorcity2920 yes you can. You will need some more resistors but it should be easily searchable on Google and RU-vid on how to do it. We had this in our curriculum in highschool and we developed it from scratch.
It is actually not named from the resistors. The company that made it used a number one of the employees thought was cool. To the reply comments here, no you cant just use resistors to make this instead of the IC. You would need many other components most being transistors.
I thought you were making a mini pod racer out of circuitry for a moment and the more I realise how mistaken I was, the more it seems like a brilliant idea 😂
@kindasusperson it produces an oscillating signal which can be controlled by a potentiometer. That's just one of the uses, and there is a lot of information online about its various uses
There are sooooo many cool 555 timer circuits out there which is what makes it popular. Any hobby electronics fan who doesn’t have a few spare 555’s hanging around is missing out. Hail to the triple nickel.
@@iliapavlovsky7330 Конечно! Здесь тиристор играл роль порога высоких и низких частот. Лампочки накаливания 220 вольт (миньоны). Плату изготавливал путём вытравливания меди медным купоросом, а в защите медных линий на плате использовался цепон- лак.
Теперь все это делается на одном чипе, типа attiny13, а все эффекты программируются, для регулирования скорости можно потенциометр воткнуть. И всего 2 резистора уйдёт.
I built hundreds of these NE555, LM555, UA555, etc. circuits in the late 70's. Now, 45 years later, I can still tell you what each pin does and roughly how fast the leds would flash. Thank you, it was a nice trip down memory lane.
@@LeMeowAuwithout proper instructions provided, the inexperienced people who follow this video are probably gonna improperly solder things together and then have a short circuit which can cause a fire and other bad things to happen.
Basically any low voltage DC source, like 5V from a USB phone charger, 2 to 4 1.5V batteries in series, etc. Ne555 uses voltages between 2 and 12 volts or thereabouts depending on if it's ttl or CMOS, and other factors, look up the datasheet,if you choose a 9V+ supply, pick appropriate current limiting resistors so the LEDs don't die
