But how will the Colombian boys ever going to figure out what "gender" they are without an unsupervised expenditure of $25 million?

My Boss I really like your lesson and l will be glad to have you as my private teacher. Am from Ghana a student of A.T.I

So how does the output voltage across the LEDs get 3.2 volt each? Whereas there is no settings for output voltage??? What if you adjust the current to 0.15A with still maintaining Vcc constant??? Will the voltage across each LEDs be still 3.2V???

Hey bro, u r doing a nice job, keep posting your knowledge on youtube, it helps us a lot.

So to prevent flip flop racing, the 7476 has a master-slave circuit and the 74LS76A has edge triggering built in? This answers a query I had…

I see from your diagram that you have an input showing +24v and -24v. Does this device work on 24v or 48v. I have no knowledge of it and am interested to learn. Also the diagram with source and sink configuration are, from what I can see, electrically the same. The current is passing through the device in the same direction. From my understanding the device is operating to a loop condition and not a current source from another device. Am I missing something here?

Please make traic instead relay with No. Nc. and Com.

MANY THANKS FOR EXPLANATIONS

Hello In your circuit, you used two digital pins but in the code you are using 4 digital pins. Could you clarify that for me? Also i have seen a couplenof articles that suggest that the charge pumping has to be done in code by switching on and off the LINs. Could you speak on this for me?

Well presented and very useful to me, thank you.

sir what is the dimension of the pcb?

Thanks for sharing your knowledge

Great contents! I am doing a project with plc controlling inductive load. My plc output =relay, how can I convert it to an inductive load without damaging my plc? Thanks 🙏🏻

How to vary the AC of a 24v transformer from 0 to 24 with a rheostat or potentiometer assuming power losses without losing the sinusoidality of the wave. with a Max intensity of 100mA. and tests with the oscilloscope.

Hi i tried it and no mater what resistor i used the current regulations was around 200ma i used 1.8ohm resistor for 666ma i used 1ohm and still 200ma output.i tried it with another 317 and the problem was the same.input voltage 16 output 9v led

Very good video. Thank you

Nice little circuit!

I have read and understand a bit of the concepts related to these circuits, but I have never built a circuit to test them yet. Thanks for the video, the circuit with the arduino may be my inspiration to try one. I have removed many triac, diac and opto related components from circuit boards. The board that I had with the most of them is from a massage chair. It has a ton of different motors and air valves and a processor that controls them all individually. I took all those components off the pcb so I have many to play with now. I may just build a circuit and test it out. Thanks for the video

This is a voltage regulator

Благодаря ви че споделихтe!

Ciao potresti progettare dispositivi e circuiti elettronici partendo da zero quindi facendo vedere i vari collegamenti e la disposizione dei componenti elettronici in modo che possa realizzarli più facilmente da casa? Ad esempio circuiti elettronici con motori elettrici sincroni e asincroni brushless, con Op amp,portel logiche triggerate e non ecc... Ok? Grazie Luca

As a hobbyist, I appreciate these tutorials so very much! Thank you Mr. Loflin.

Ciekawy materiał , dziękuję.

Connecting Load to T2 is important. Learned it hard way :D Testend with a Lamp on T1, works. Then I etch PCB, connect to Motor and it blows up. :D

Have you tried a 'tickler' coil (reaction here in UK) which would make the receiver significantly more sensitve. Like the construction method which lends itself well to experimentation and circuit modification. Keep up the good work!

Thanks for sharing your knowledge 🙏🏾🙏🏾🙏🏾

add thermal paste & heat sink on the 10 watt resistor

Does this need flyback diodes to catch the back emf from the motor?

In the Texas Instrument documents the schematic on the left is published as a current limiter and not as a constant current source.

Thanks You of Argentina

I didn't find a 100uf capacitor, I only found a 10uf capacitor, could that work for me

Ok! That vista driver doesn't work with my k150 clone, gives the error about being phased out. But here's what worked for me, somehow. Go to device manager, right click the error, then update, browse, let me pick, select disk, and select the driver from 3/12/2010, v3.3.11.152. There was another one on my computer from 2008 but that didn't work either, anything >2010 doesn't work either (there's only two of them, each from 2021). If the driver isn't installed, google around because it's probably out there somewwhere.

Someone asked about this circuit switching speed compared to a PC817 with an NPN bipolar transistor output. It is slow and can't be used due to the turn-off circuit within the device. I have used it with the PWM off an Arduino.

I am making a same thing, not h bridge, 5 hp dc series motor, can you suggest anything

Sir, you solved a big problem for me, it was a nightmare, thank you so much

Hey, I know it's been 5 years, but I was thinking it's worth the shot asking away. I'm working with TIP120 transistor to power a heating element with a current draw of .3A when powered by a 9V battery I'm struggling with breadboarding it though. I'd assume I'd have something similar to you: Arduino DP has a resistor that connects to the base pin, and then the current flows from collector to emitter, through the 9V battery and through the heating element. My problem is that my circuit is able to turn on the heating element, but it's not turning off when it the DP base input is low. I was thinking that might be because of how my collector to emitter circuit does not connect to the ground pin of the Arduino - it only consists of the 9V battery and the heating element. I was wondering what connecting it on a breadboard would look like? Would I connect my emitter pin to both the Arduino ground (which I'm setting to the negative rail of the breadboard) and the 9V battery as well?

I love You Sir..

I've been looking for somebody competent in this subject for a while. I know solar charging systems do not have anything like I am going to explain so I'd like to build one with arduino , comparator circuitry, etc. Essentially I'd like to buy 4 massive powerwall battery banks and create a rotational charger using limited solar arrays. I would use one charging source and use an Arduino to control relays by comparison of voltage. One battery bank would be connected to the load, our 240 V 100A AC home panel via 48VDC to 120/240 AC via inverter. We would precharge all 4 banks, use the highest voltage bank as priority to feed the load, and simultaneously charging the rest of the 3 banks. Once the load battery drops to a cutoff voltage, the Arduino would switch to the next bank, switching to charge the low battery formerly used to power the load, as well as the other 2 batteries (maybe just maintenance for those if already fully charged). Pretty much infinitely rotationally switching as needed to power the load. When solar power goes away, it would obviously have to switch back to A/C power for charging until the solar picks back up again. I do feel this would make the batteries last longer due to normal cycling, and have less abuse to them as they would switch at maybe a cutoff of 47 volts . I am trying to figure out the switching scenario possibly using contactors since they are much better and longer lasting for the higher currents needed to power the home panel which would be close to 500 Amps at 48V absolute maximum since the home consumes about 30 to 35% of this energy at the same time pretty much at maximum outside of moments during startup surge/inrush currents. I do know it would be best to change to gas or propane for cooking, or other means than electric and try to eliminate heavy resistive loads such as electric heating. Let me know if you have thought of this kind of tech for off grid solutions. I think it would have to be produced on a public domain level because it would interfere with the use of electric company's power all together if sold to the public. I think it could significantly help those who can't afford the bills to have a system that could store the energy long term and get through days of no solar energy (during gloomy weather) with ease having the ultimate in energy storage and battery maintenance.

Which of the programmers do you recommend please

tnx

me dice: Please check... Communications port, currently [COM 3] Board connections and power Mode = [K150], make sure this setting matches programmer board

Hi , Please how can I get this radioactive disc ? Thanks in advance .

Resistance increases as it gets hotter.

Hey lewis , how are you . This is mark I use to work with you at bristol.

hey , thanks for the knowledge. By the way, I think your tea pot is ready to be served!!! it sure sounds like it!! enjoy it

Very good Informations 👍🏻👍🏻👍🏻

SUPER VIDEO. why do they say something about 4,9501V to set up resistors or reference adj only?

This is a current buffer for switching

Hello sir what to do if an sensor is involved? For exampel an reluctor sensor for ignition system so is it necesary to rectfi the signal first to use it as an input signal for the octocoupler? I need just to run an small transisror you see wia external power supply I simply surche for an alternstive methode to some how build an transistor based phase shifter 0-180°+ variabel so Im curiuse on what frequency ranges those octo coupler operate? And what correct components to chose for the rectification methode I only know my reluctor has 1.35henry around 300Ohms rating the operation frequency is about 0 to 1khr most of the time amps and volts are in mili range .So hoppe you know some octocoupler who does operate fast enough and in those mentioned ranges ?

cool video, I have a tc-1 tester, but can't test bc517 or mpsa13. is there a way to test with multimeter or do I need to buy the atmega328. alternately how do I test with multimeter?
