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?????
What formula do you use to calculate diodes and resistors in 1.5V batteries, for example? How to calculate?
The charge level of 1.5V batteries cannot be calculated with LEDs that require 3V power.
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
better to use a d'arsonval meter
MY GOD DO NOT CLIP OFF THE LEADS UNTIL ALL THE SOLDERING IS DONE
SEEMS YOU KNOW VERY LITTLE
THIS IS JUST A VAGUE INDICTOR AND HARDLY IS WIRTH THE TIME
its vague since it depends on the vf of the LEDs and diodes which vary and vary by current
WHAT IS THAT TAP TAP SOLDERING.........MY GOD
LEARN TO SOLDER
🤣
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
