6 Amazing homemade devices that will amaze you

I love the "voltmeter as motion detector" idea. Very clever.

It would be an added value if it were explained why certain components should be used and how they work within the project instead of showing that by connecting them together they just work

[@Inventor_AW]

I apologize.. However, if any viewer has a question, I will answer it in comments

[@acmefixer1]

The project that uses two pushbutton switches to turn the power MOSFET on and off is dependent on the charging and discharging of the gate capacitance. This charge could leak away when the humidity is high. It's a poor circuit design. Project #4 used two LM358 dual opamps, but an LM324 is the same as two LM358s in one package. The guy needs to watch videos on how to solder. Thanks for the videos.

[@Bob-1802]

And my two cents about the two-button project #2: at least two resistors should be used. In case someone comes up and pushes both buttons at the same time💥

[@joewoodchuck3824]

Not everyone wants to stock two versions of the same ic.

[@Pc110]

May I ask you a question? This is a circuit diagram using an analog meter that makes the LED and buzzer sound when it shakes, but even if I follow the circuit diagram, the buzzer keeps ringing and the LED lights up all the time. Are there any mistakes in the circuit diagram? I would like to make one too, so could you please let me know?

[@Inventor_AW]

The diagram is 100% correct. Check all the connections and try changing the variable resistance value to 500 ohms instead of 1 kilo ohm.

[@Pc110]

@@Inventor_AW good morning. thank you for your reply. The circuit diagram is definitely smart. Regarding the 1KΩ variable resistor you advised, I am currently using 500Ω as instructed in the circuit diagram. The one thing I'm concerned about is the 1N4148 diode, but is it okay to use it as a signal diode? In the video, it looks like there is a rectifier diode attached, but are you sure it is a glass tube diode (for signal use)? Also, should the LED be a 3-6V compatible LED? I am currently using a 3V compatible buzzer. Could you please let me know if there is anything wrong? teacher!

[@ashfaqjuna]

That's art in a way. Great skill. I like it

[@Inventor_AW]

thank you@@ashfaqjuna

[@NullCyan]

I appreciate the skill, I have tried soldering this way and it's kinda hard, but yeah, a perfboard or a PCB would be more stable. Maybe the point of soldering in this particular way is to show where each connection goes.

[@ashfaqjuna]

@@Inventor_AW I seriously think that you can teach this skill by example. It will attract a lot of hobbyists and experimenters. It's a great way to prototype something quickly and if it's done on a copper clad board, that can act as a ground plane. Furthermore, if one encapsulates the circuit in clear epoxy, it becomes an interesting item to present to all sorts of audiences, because it will be visible, safe to touch without risk of injury or damage to the circuit.

Thank you sir for your amazing video, can you please explain give more details for project #1🙏

[@Inventor_AW]

For the first project: When the photodiode receives infrared radiation, it passes a positive charge to the MOSFET gate, then the MOSFET connects source with drain , the 0.47 capacitor delays, then the 1 mega resistor discharges the charge. And so on

#6 is a great idea. Thank-you. Re project #5, the high side of the transformer generates a lethal 220 VAC. It would be great if you were to remove this project from an otherwise fun group of circuits.

[@Inventor_AW]

Thank you.. Project No. 5 is an inverter and many people need it

[@harrickvharrick3957]

220V AC is hardly ever lethal, in the first place be cause it is AC which is much less dangerous as to how it can immobilize the muscles than DC at similar or even lower voltages (it was one of the several reasons in the day to go for AC, others being its far lower transport losses and the fact a 'moving' magnetic field is needed for bopping up or lowering voltages by means of transformers) especially if it is at a low Amp rating which this obviously would be and also it forms a closed loop so to say so in this case the electricity would not want to leak to any external 'earthed' polarity. Although I DO have knowledge of a washing machine repairs man who once accidentally got electified when crouched down on the bathroom floor (doing a repair whilst the home owners had left the house in the meantime) for hours on end whilst he could not move his body and thus could not get away / stop touching the electrified part(s) which caused him quite a physical trauma, even he survived. I have accidentally touched live 220AC wires many times in my life and as long as you wouldn't stand with your feet in water, it would not kill you. By the way modern safety measures included in our home electricity networks nowadays would even in the latter case prevent you from getting electrocuted as well, and even from getting any serious yolt - when it gets outside of the closed system it is supposed to stay inside, the power in our homes gets disconnected (switched off completely) so fast that it hardly can do any damage to any living being at all!

[@stellarspacetraveler]

I would think anyone with the inclination to build #5 will already know about high voltages. I understood that when I was 10 years old.

[@Inventor_AW]

no

[@igorzherebiatev5751]

​@Inventor_AW Why? You used 2 lm358p, each containing 2 op amp. Lm324 contains 4 op amps with the same schematics. So just 1 ic instead 2

[@Inventor_AW]

In the diagram, it looks like I used 4 lm358, but they are only two, but in proteus - design software - lm358 Moken it is two pieces.. Look at the leg numbers.@@igorzherebiatev5751​
