      Dear Sir, Not only your politeness behaved amaged me! but also you are a simple gentle person! it's my feelings to you ! I am a young man of 76+ , passing my liesure period watching various kinds of videos in you tube. Electronic job is hobby! and a little electronic job I am very much fond to it ! Sir , who told you that you don't know English well ! Your politeness will covered all your defect ! My mother language not also English? But somehow I managed. I was a former Executive of SAIL( Delhi) . Retired on 2008 . A lot of thanks for your knowledgeable as well as informative video too. Please stay well and be happy to make new video for us. A lot of thanks with warm regards Sir.

    You had me at, "enough talking, let's make something" finally a tutorial that's shows how to do this without the extra info. The videos for these types of circuits are ubiquitous on UA-cam. I know some folks need that extra info, but I am only interested in how it is put together. I am not smart enough to understand exactly how it works.

    I just found this video and found it quite fun to see this skeletal method of circuit building. I had used the 317 to create a self regulating heater circuit for my 1950s model train. I added a thermistor as the R2 and a fixed reference resistor for R1. There is a heater coil on the output and it is used to vaporize an oil in the smoke housing. I also have a small DC Can motor and fan to blow a puff of air through the housing in synch with a Chuff Sound board. If the Heater gets too hot it can burn out or use up all the oil in the housing. If it gets to cold the oil stops evaporating. Other variables i had to deal with is the Track Power that runs the motor in the engine starts at 5 volts and goes up to 17 Volts. I isolate the 317 from that variance in track power by 1st converting the AC to DC then running it into a Buck Boost Board set to 9 Volts. I find that with the heater I used 8 to 12 Ohms will heat up to 150C with 9 volts. The other variable I had to accommodate was the fan to make smoke flow out. It will cool the heater down as it pushes out the smoke. When all put together the heater will start up at 9 volts as the thermistor is very high resistance as room temp 25C. As the thermistor sees the Temp approaching 120C it will start to reduce ohms and being R2 it lowers the output power. Then as we turn up the track power the fan moves air faster so the thermistor will cool and Ohms will increase which raises the energy sent to the heater. If i have all the parts correctly balanced and the right R1 value the system balances between 120C and 130C quite nicely. This provide a nice puff of smoke at low speed leaving the station, then once on the main line and speeds increase the smoke maintains a nice plume out the stack as the engine speeds along. Then as we slow down the Thermistor will begin to heat up with less air flow and that will lower the energy coming to the heater. It all works really nice. We used to have good smoke at low speed then none at high speed or burn up in low speed and have smoke at high speed. It was a battle to have fun smoke at all speeds. this 317 is so simple and easy to configure we even have a circuit board made and we can sell the assembly to other Train Hobbyist. And it is all very affordable for them. I appreciate you continue to teach today and applaud your efforts. I try to share with other train folks but these older trains are left with older guys now so it is harder to bring young ones along. We are using 3D Printing to make spare parts and new engines. We hope to bring new Hobbyist into our model train because it is a very good scale. 1/64 scale which is larger than HO but smaller the O (Lionel). I am trying to use science and technology to help keep it alive. We are now finishing our Sound System with ESP8266 Microcomputer. I am at 73 learning C++ AGAIN! But with Arduino and these new boards it is all part of the IOT and STEM like studies which i find online like this lecture and demo you made for us to learn from. I wish you very well and hope you get many more viewers. Thank You for a great video, Dennis in Virginia USA

    As seen by other viewers, I too viewed many videos creating this circuit. Yours by far is the BEST of all viewed. I was able to build one, but still waiting for the screw connectors to arrive.I just used solder.
    You seem to be a most friendly man who knows how to communicate with others.
    One thing and if you can help, I am having trouble locating the resistor. I can find the 220 but it is the physical size that is hard to determine while looking online.

    I have a question. I am trying to build something that is a bit unconventional to most people. I want to build a vape mod that is voltage regulated. I prefer to have a buck boost converter, but I cannot find one that is within the voltage specs that I am looking for. I want to have the ability to use either a single 3.7-volt battery or a dual battery 7.4v but it must have a 2.5v cutoff. I want to be able to adjust the voltage from 0v-10v on the output, and it must be able to withstand 30 amps of current, these devices produce a lot of amps running through the system and most boards I see can only output 2 amps which is nowhere near enough. Any help will be greatly appreciated.

    I had searched for a variable voltage regulator, but I was wondering if you could do it in reverse and increase the voltage from a 3.7v 10a-20a 18650 battery? Could this be possible?

    Izvrsno zemljače. Ohrabrio si me da napravim regulator za malu željeznicu umjesto originalnog starog Mehano. Radi fino jedino što napon u tračnicama ne pada ispod 1V. Ali ionako da bi se vlak pokrenuo treba mu bar 3V.

      Poslao sam mali video testa, i to 2x ali ne vidim nigdje da je poslano. Nadam se da je stiglo. Još trebam ugraditi polarity switch za naprijed nazad te sve polemiti kako treba i složiti u kutiju. Prethodni projekt mi je bio brzinomjer za male vlakove preko Arduina. Nisam se odvažio objavljivati na UA-camu. Vama svaka čast i moja podrška za daljnje projekte i objave.
