thank you very much, I used this to use a 18650 battery in place of a AA battery, that runs a month and then I have to replace it in a Wall Clock....Then if needed I can recharge them on a charger....I replaced the mosquito rackets with them, always using a box, not soldering into the battery !
Hi.. what's the differences between (this vid) your circuit compared to the circuit using capacitor/elco.? Does your circuit will last longer with a new 18650 lithium battery compared to circuit with elco.? Thank you.. 🙏🙏
I have successfully completed this project. But then again I have done a similar project in which the output is 1.47v to 1.53v but the clock is not running but it is running on battery. What shall I do?
please Sir, -how to do same project for 100mAh battery 3.7V. I need install inside my Seiko 1.5 volt quartz watch . thank you so mucb Sir. you are genius
Сделал всё как на вашей схеме, при полной зарядке 18650 -4,2в получаем на выходе 1,62в, 3,7в-1,37в, 3,0в-1,05в, 2,50в-0,8в, напряжение на выходе при разряде батареи тоже падает.
То что напряжение падает, понятно. У меня обнаружился другой эффект. После замены обычной батарейки на 18650 с этим конвертором увеличился ток потребляемый часовам механизмом практически в двое и часы стали безбожно убегать! За 8 часов на 30 секунд. Как с этим бороться?
Can anyone suggest a similar 3,7v to 1,5v chinese cheap product with low heat disipation in loud (i want to connect a small 1,5v E10 very low light ambient bulb) and minimum consumption in stand-by? Thank you
Hello Does this circuit consume any energy while it is at rest? Does the transistor consume a certain amount of energy if the output is not connected somewhere?
Setelah diuji dengan menggunakan diagram yg tertera terdapat kelemahan yaitu output dari arus yg dikeluarkan sangat kecil, ada beberapa jenis jam yg tidak mau jalan.

Not reliable and will not produce the required Amper to run the attached devices beside heat. Solution? Use a voltage regulator like AMS1117 with your required voltage like 1.2v 1.8v 2.4v 3.3 etc. it's perfect and output fixed stable voltage and about 800mah without any heat. 👌

For a voltage drop from 3.7V to 1.5V it is sufficient to connect 3 diodes in series. On one diode the voltage drop is about 0.7V. (3.7-1.5=2.2V).

Increase small value of Resistor 2 connected to GND will increase output voltage
How many value resistors should you put in relation to the small value register?
