Glad it helped & Cheers! 🙂👍

You're lucky & Cheers! 👍

Thanks for your interested, Mate! The sizes of resistors in the video showed are applicable in the most practical situations, in your case I'd say that resistor was 0.5 W instead of 220 ohms 1W however it could be otherwise. 🙂😇

Glad it helped & Cheers! 🙂👍

Thanks for your interested! Theoretical speaking, the voltage between (+) and (-) is V - 2 x 0.7 volt = V - 1.4 volt (here V is input of AC voltage). Suppose V is 230 volt then the voltage between (+) and (-) is 230 volt - 1.4 volt = DC 228.6 volt, however if V is 2.5 volt then the voltage between (+) and (-) is 2.5 volt - 1.4 volt = DC 0.9 volt. Cheers! 🙂👍

Thanks bro🙂

Thanks for the interested, Mate. Well the DIY device in the video showed was just the one of ways to make your own convenience SMPS power supply. Everyone's circumstances might have been different, the one can make his/her device according to the materials or parts they have. Cheers!

before or after it killed you?

Thanks for your interested! The DC output capacity for this DIY power supply is 40 watt, so its max current: I = 40 W / 5 V = 8 amperes also the components of the output have been chosen for 8 amperes as max allowable current. In practical as the the video showed, a car's bulb rating: DC 12 V / 21 W so across its current was 21 W / 12 V = 1.75 amperes. Cheers.

Cheers 👍

Glad it helped. As always, share my experiences and do my best to explain & answer if I can. Cheers! 👍

16 volt. 👍

Good idea / Cheers! 👍

Thanks for the interested! Mate, your intention are: A 3 phase AC motor to run by single phase AC power then how to connect a capacitor to that motor, am I right? <1> make sure the motor has been connected by Delta (∆) in the motor's terminals box. <2> Then, a capacitor can be connected to any two terminals in the motor's terminals box. <3> Finally, to connect Live(L) wire from AC power to the one of the capacitor's terminals, Neutral(N) wire from AC power to the terminal in the motor's terminal box which has not been connected by the any one of two wires from the capacitor. That's it & good luck! P.S. - It wouldn't be any good for a 3 phase motor with the larger capacity (a motor > 1 kw)to run on singe phase AC power.

Thank you for the interested! For your question, as an example by referring to the volt/ammeter's diagram connected at 4:35 on this video: Connecting your DC buck converter's output positive(+) to the load's positive terminal which is on the top left corner from the diagram, then connecting the load's negative terminal to the one end of shunt (this end of shunt is also connected to Thick Red Wire from the meter) which is on the top right corner from the diagram and finally connecting your DC buck converter's output negative(-) to the other end of shunt (that end of shunt is also connected to Thick Black Wire from the meter) which is at the bottom of the diagram. P.S.-- Be careful with the wires in different colours and also Thin Red & Black Wires are for the meter's power supply which its range is DC 4 to 30V. That's it, good luck and enjoy! 👍

@@diymade2175 Thank you kindly Sir. You are a scholar and a gentleman.

@@larrypridgen4785 Thanks Mate & glad it helped however I'm neither a scholar nor gentleman yet. I'm a person who is very much interested to do DIY projects and like to share with everyone. Cheers! ❤👍

Thanks for your interested! Well, as your intention: P = 12V x 5A = 60W for the DC power to charge a battery, the 14V output from a transformer can be chosen either center tapped or not. In this case, a transformer's core area can be designed as S = 10cm2 approximately. I leave to you for the rest of the details. Enjoy & good luck. 👍

12 v 10 Ampire transformer 4ah bike battery charging pannalama yes or no sir

@@kalaivananA1990 If your bike battery is 9V/4ah, yes 12V/10A transformer is alright to make a charger for that battery however, no if your bike battery is 12V/4ah. 😑

Yes. A draft diagram has been there in the video, from 4:27 to 4:37 although no actual connection showed. From diagram: The Positive(+) which has a Thick Red & a Thin Yellow wires together on the top left is for the load from another source's positive and the negative(-) which is a Thick Black wire on the bottom left is for the load from another source's negative. Cheers! 👍

👍🙂👍

Thank you for the interested! The actual load(s) was 117W combined with a globe + led type lights + a fan, however a 50 Hz oscillator or mosfets could at least withstand for 200W.

👍

Thank you for the interested! The motor itself in the video showed has only one speed however you can change its turning direction by arranging a different way to be connected from the power. In order to control the speed of the motor in the video showed, you have to add an AC Motor Speed Regulator between the power and the motor, that was not showed in the video. Thanks again!

Thank you for the interested! You see: L = 0.00318 * R * Vl / Vr in Henry, it can be L = 0.00318 * R * Vl / Vr * 1000 / 1000 = 3.18 * R * Vl / Vr * 1 / 1000 in Henry. Then it also can be L = 3.18 * R * Vl / Vr in Milli Henry [L = 3.18 R (Vl / Vr) in mL for short in the video showed]. That's reason 3.18 showed. Thanks again.

That'd indicated the motor had the kind of faulty and you were right at this stage but it might have indicated other cause (s), certainly it needs to do further investigate if you'd want to be sure. 👍

Thanks for your interested! If all windings were equal in ohms, I'd say the winding (s) in that motor were at faulty such as some part of winding (s) burnt or short completely. The motor needs to be disassembled and further checked.

😗😶🤔

Thanks for the interested & yes, you've spotted one thing on! To put it in the simplest way for answering: The reasons for attaching a capacitor to a single phase AC motor are (1) Easy to start motor & then run it smoothly as you've mentioned. (2) To improve Power Factor because the coils inside AC motor as whole can be seen as an inductor in the AC circuit, so you might have known already - an inductor has the voltage 90 degree advanced over its current however a capacitor has the voltage 90 degree behind its current, in practical circuit a capacitor & a motor together will compensate some phase angles each other but all, that will be the result for improving Power Factor for whole grid system (for your own benefit, improving Power Factor, the less current goes through your home elec meter, the less the power bill you have to pay).

Cheers！👍

Cheers, Glad it helped & you're a champion! 👍👍

I love your question, Mate! Yes & No!!! This DC mini digital meter's limitation: Max 100V & 100A which it can only withstand! it will be okay for starting current from motorcycles or mini cars however for other cars' starting current can be range of 100 to 250A in the most cases, so it'd be highly likewise to blow off the meter & shunt. Incidentally speaking, the way of mini meter & shunt connected in the video showed must be seen as whole thing then to connect it to whatever the circuit is. Good luck! 👍

@@diymade2175 so i have to connect the shunt after the starter, but how can i connect the shunt in a positive line, in the video shunt goes in the negative. As all my electrical equipments are grounded to body where can i connect the shunt? Or better to connect in the alternator line?

@@arunck5779 Theoretically speaking, you can connect it in either ways: In the alternator line or after the starter however in your case, to connect in the alternator line would be challenging & cause some troubles in the practical situation. It will be better to connect it after the starter: (1) Disconnecting negative(-) terminal cable from your car's battery. (2) Connecting Shunt's one end (Thick Black Wire connected from the mini meter) to car's battery negative(-) terminal, of course you have to use a suitable cable which can withstand starting current such as a jumper lead. (3) Connecting Shunt's other end (Thick Red Wire connected from the mini meter) to car's body or the Black cable that you disconnected from battery negative terminal for seconds ago, again by using another jumper lead as you wish. That's it, then start your car and good luck & enjoy! 👍

@@arunck5779 One more step missed: (4) Connecting Thin Red & Yellow wires from the mini meter together to car's battery positive(+) terminal. 👍

Thanks for your question! Primary windings: Center tapped - 2 x 10 turns & 20A wires or cables. Secondary windings: this coil was original "primary windings" from MOT, I didn't know exactly its turns however by the actual tested, I'd think it had 220 turns approximately & AWG 16. Enjoying your experience! 👍👍

Thank you for the interested! DC 4 - 30 V is the range of Mini Digital Vol & Amp Meter's supply voltage: In order to let the Meter work, it needs to have a DC power given (such as DC 5 V, 9 V, 15V, 24 V & Max 30 V etc). On the other hand, DC 100 V & 100 A are Max voltage and current that Meter can measure for the practical circuit in use for example: You have a DC motor with max 72 V & 12 A capacity, then using the Meter in the video showed to measure or monitor that motor's running Voltage and Amperes. Cheers 👍

4 to 30 volts to power the meter on the red wire, and measured volts are 0 to 100 on the yellow wire

@@JeffreyPar-pr2zw 👍👍

Thanks for your interested! Well, I was not sure how many turns for the primary coil however by the actual tested, I reckoned the primary coil would be 270 turns(240 V) more or less. the secondary was 16 turns (14 V) center tapped which means 2 x 16 turns(2 x 14 V). Incidentally the more details can be read on subtitles, just turn on "CC" on your device.

Cheers 👍
