How to make NE 555 pulse adjustment speed control board

The batteries you used are not rechargeable , are they?

贴一个贴纸都不会！真差劲

Wi-Fi not working 😢

后面三种其实是一样的。所以，本质上只有两种。

See “This side up”

Does anyone know what parts needed to make this for 2 AA rechargables?Preferable also with an outgoing of 5 V 1 A Nice channel this!keep up the good work

The words said to place it with the arrow up, do you think that would have made a difference?

FAKE PRODUCT. DO NOT BUY. MAKES NO DIFFERENCE TO SIGNAL WHATSOEVER!!

Can i use it for 3 aaa cells at once?

great video, some information, I bought the same model of power supply from ebay, I don't know if it is defective, not having an identical model, I will describe what happens, if I load a 300w medium absorption rx580 video card, I hear a strong internal electric hum and normal? then without any boot board connection, i just apply electric plug it starts the fan starts automatically, is this normal?

要向上⬆️贴兄弟。

Do you know how to make it adjustable from min (1-2V) to max (12-14V) PSU?

Thousands of lifetime projects with Woodglut plans.

+1 for the idea but you need to improve it

还是第一种简单呀，两根线就可以把两个串起来了，其他的线有三个

论述 明确又清楚是最好的示范……好！

Wait.. you just used 2x 1w resistor in parallel to achieve that?20 ohm each (10 ohm total)?

BT136 is not SCR. You are wrong! It is Triac

i used 27k resistor and RL 207 diode. The output voltage was 7.3 volts. Try at your own risk.

Kia me bta800b use kr sakta hon g

How many turn in toroid?

what other diode can we use ?

does it light green when charging completes ?

Omg can anyone narrate explain what you are doing instead of playing fucking music

Circuit diagram please🙏

Hi, good day! I'm planning to make a stunner with a voltage regulator like this. It is safe to make one with a wire diagram like this?

You have to remove the cover and battery then put it in so it's actually on your antenna

Can u provide this kit

Genius idea..

Can you please draw a circuit diagram. It will be more helpful.thankyou

You used those resistors as a heating element? You are such a lier and full of shit, you are trying to fool people just for the sake od producing a video!

زبردست

can i use this on my 60W soldering iron to control voltage?

it charge batteries until 4,2 volts/2 ... . 2,4 volts each one....

can i use it for dc 150volt....?

One IC 1815

What you 1.5v to 12v in its

👍

I have one more question: 1)This diode is not available in my area BA157 .. any other diode which I can use? Regards Rahul

Or you might want to buy step down board

Timestamp for where you have circuit diagram. I can't find it.

What is the best way to contact you? I need some consultation work from you if possible :)

price koto taka

Bt136 is atriac and not a scr. It's diffrent

Its just a Decoration😂✌🏾

Read the instruction. You got to open the backside of the and take out the batteries and then put the booster signal upside up. Then put the phone back and then turn it back on. Now check to see if your internet is a boost

Do we need to use 103 cap also, or only 104 is enough?

hello sir,can it be use for board audio amplifier 15v ac?

Sir i want 10 pieces
