8. In the project, is there a chance to make a circuit that opens and closes automatically when pressed 2 times within 3 seconds instead of holding the button down?

Wow, great video. Where did you get the thin wire to solder to the circuit board? Thanks!

I really like your videos. I have two questions. How hot is your iron? Do you have electrical schematics for your project? I am knew to all this, and when you fli[ the board over and start doing connections, I get lost. :(. A schematic would help lots. Thanks.

Hello, I like the no.10, it is ok to use 4 leds only? And, for 3v to 3.7v battery as my supply?

@NickBarban

Жыл бұрын

Using 4 leds only is fine. You may need to adjust the resistor values for brightness. 3.7v is fine. Red LEDs are rated at 5V reverse voltage. Just make sure to connect it the right way round

Hi brother,can make a circuit for glow plug timer using 555? It needs to be turned off after 5seconds time or adjustable timer.when the input power applied it should turn off output after set time by pot.but input power to the circuit remains on. Simply off delay timer with a push to on switch,(not a push button switch)

I once saw plans for a radio using a 555

2:30 It's not really worth using a 555 timer for this circuit, just use any NPN transistor, check the pinout and match it to some other videos. There's a whole lot of them out there!

3:20 Is that a 33KΩ or a 3.3KΩ Resistor??? I don't want to mess this up. Can you please tell me which??

Aap video ke liye 👍

you call a "zero pcb" a perfboard. a "dark sensor" can be used as a flashlight but more efficient

You can use a lower value capacitor or you can change the 555 IC 6-8 pin's resistance.

@@estechknowledge it doesn't matter in this case either because; I have to leave the button on for 800 milliseconds and off for 200 milliseconds, I have to finish the discharge process in 200 milliseconds after the first charge, is there any other way...?

you missed the point... the LEDs can be replaced with OTHER things... like motors, servos, etc. these are just projects to get ideas from, not to actually build..... unless you are 9. also, many are actually incorporated in everyday appliances, like the touch sensitive switch, and light activated (photo-sensitive) lighting. your phone or tablet or tv uses it to dim the screen at night. so they arent useless toy circuits.

At 3:19 that's pretty clearly a 3.3K resistor, not the 33K that the captioning shows.

true.... so true, ha! I wonder how many people messed that one up.

So, why was the 555 necessary for the first circuit?...

What do you use for the 4v power supply in your projects? Would a 3.7v battery work?

Has anyone figure out yet how circulation pump motor works? I know it uses gate driver in IC to drive gates in IGBT. It is 3 phase too. pump name Wilo made in sweden or something. Same shit is in those compressor heater/cooler, the fans are run by PMM thats driven by weird pwm using gate drivers and IGBT. I wan to make them run on 12 or 24v DC. Any smart person here? I could even pay if you know where to tap the pcb.
