yet another problem with this is the current usage - a bit dumb for use on a battery unless it has high AH

better to use a d'arsonval meter

期待用 (Charging cable + type-c)示範，拍攝更多的影片。 Looking forward to using (Charging cable + type-c) demonstration and shooting more videos. Usb 5V + TYPE_C + LED

what?????

@arthurlothammerfilho4560 7 месяцев назад

What formula do you use to calculate diodes and resistors in 1.5V batteries, for example? How to calculate?

@TECHIDEASCENTER 7 месяцев назад

The charge level of 1.5V batteries cannot be calculated with LEDs that require 3V power.

@kennmossman8701 3 месяца назад

ITS N X 0.65 PLUS THE VF OF THE LEDS WHERE N IS THE NUmBER OF DIODES IT IS RATHER CRUDE WITH THE LOWEST VOLTAG OE 1.8v ASSUMING YOU USED RED LEDS THERE ARE BETTER CIRCUITS BUT DON'T EXPECT TO SEE THat HERE

MY GOD DO NOT CLIP OFF THE LEADS UNTIL ALL THE SOLDERING IS DONE SEEMS YOU KNOW VERY LITTLE

@kennmossman8701 3 месяца назад

THIS IS JUST A VAGUE INDICTOR AND HARDLY IS WIRTH THE TIME

@kennmossman8701 3 месяца назад

its vague since it depends on the vf of the LEDs and diodes which vary and vary by current

@kennmossman8701 3 месяца назад

WHAT IS THAT TAP TAP SOLDERING.........MY GOD LEARN TO SOLDER

@TECHIDEASCENTER 3 месяца назад

🤣

@kennmossman8701 3 месяца назад

this rather poor circuit has been done a thousand times before you offered no insight./ advice, no explanation weak EFFORT the voltage points are a joke since it depends on the Vf which varies.....you ought to measure and match Vf first
