floating

I was tasked to build a constant current source for electrical stimulation, which can generate different pulses and up to 60-70 mA. And i achive it through using the Improved Howland current pump. Now I was asked to build a “true biphasic” output by using two Howland pumps across the same load...

What is the role and purpose of the 470uf capacitor? Is it simply disconnected because it's connected in parallel with 330uF? And 5 pin out is 15V pulse or low pulse? What is the expected transformer ratio?

I was wondering what are the disadvantages of floating ground (for example the chassis of a caravan) over earth ground. It's seems to be safer to left unearthed a chassis in order to break the grounding loop that exists in an electric shock event It is related to the electric potential of the...

Hi folks, for a uni project I’m creating a synth using an Arduino. I want to have at a minimum 8 buttons for an input but I’m restricted to using only 1 or 2 input pins. Therefore I wanted to use an ADC to convert the input to binary values. I wanted to use no IC’s if possible so tried using an...
