Background I am building an RC Car that I am trying to modify to control from an Android phone. When I connect the remote control module as well as the car circuitry (servo & motor) to separate ...
As I child, I had this electronic construction kit called Elektronik 1. It was manufectured in former Czechoslovakia, based on resistors, diodes, bjt transistors, capacitors, an LW+SW radio antenna ...
I know there is a minimum forward voltage for diodes, however, is there a similar property for current? I'm trying to use something like a BAT54C as a steering diode such that a 3V lithium battery ...
1.why we cant use diodes in place of battery?we are getting 1.4v in a cheaper cost than battery.but why we dont use? 2.if electrons are moving in a single direction it releases many energies but why ...
I use a home weather station. It is powered by two AA batteries (2 x 1.5 = 3.0 V nominal). The problem is that it eats more than 1 mA and that is quite a lot of power and I must buy a new pair of AA ...
I have an RC helicopter with a dead 250 mAh lipoly battery with a voltage of 3.7 V. Could I use 3 button cells at 4.5 V and a diode with 0.7 voltage drop to power the circuit, which is somewhat ...
