Essentially, a high current is transformed into a lower one using a magnetic carrier, thus very high currents can be measured safely and efficiently. In most CTs, the primary winding has very few turns, while the secondary winding has many more turns. This ratio of turns between the primary...
Below, the Left picture below is where this page of the instructable finished and the picture on the right is the Red Positive wire link in place to connect both the top and bottom power rails (Many thanks for the catch abqlewis !!!) Now you can take a quick break Carry on into: Or...
18650 cells, which are used in many different consumer electronics from laptops to power tools, are one of the most common battery cells employed in electric bicycle battery packs. For many years there were only mediocre 18650 cells available, but the demand by power tool makers and even some ...
As the battery gets larger, the increase in flight time becomes ineffective. Eventually it will reach a point where it just doesn’t gain any more flight time with bigger battery (even lose flight time). This is mainly caused by the weight of the battery. Also note that the heavier your...
In this Arduino Tutorial we will learn how to control a Stepper Motor using the A4988 Stepper Driver. The A4988 is a microstepping driver for controlling bipolar stepper motors which has built-in translator for easy operation. This means that we can cont
To calculate the amount of current that would course through a person’s body if exposed to 120 V, simply divide 120 V by 600 ohms (I = V/R), which totals 0.2 amps or 200 mA. That’s more than 2.5 times the lethal limit of 75 mA, so protecting yourself and your workers against...
a sonar. The sonar sends out a sound to an object that is an unknown distance away. That means the sound has to travel this unknown distance twice (there and back). Now suppose your microcontroller says the time passed was .03 seconds. How many meters away is the object from the robot...
This is wheremany people select the wrong chargerfor their actual needs. From myLiPo battery write up, you have a good understanding of the amount of charge current measured in Amps that your specific battery can handle. You must understand that before you can determine what size charger you ...
Unfortunately the scenario I laid out for a Coulomb/Ah counter is just ONE of the many ways these devices can become tripped up and lead to inaccurate readings. There are many more "gotcha" scenarios that can rear their ugly head, including shunt wiring mistakes, battery temperature, false re...
