There are various criteria that govern how well power is taken from a nearby changing magnetic field: Distance. The magnetic field diminishes rapidly with distance from the source. Shielding. Pick...
I was looking at this design: It uses MC34063 as switching controller. I wanted to adapt this circuit, and I was busy trying to pick R1 value. The datasheet has following formulas: The issue I hav...
$$\boxed{\text{What maximum value of } I_{OUT} \text{ did you have in mind?}}$$ Using $I_{OUT}$ and $V_{OUT}$ we calculate power uplift. Using power uplift and switching frequency, we calculate how...
I want to include a wirelessly charged battery pack into my design. However, I am worried that the wireless charging could damage my main logic board. What considerations, apart from not having loo...
Why do we use open collector / open drain configurations in circuits? From one source I learned that LED controls are of two types- (1) Push pull,(2) Open Drain.Why do we use and what is actually h...
I answer to myself because I believe this subject is interesting and not very well understood, even to professionals. Also, I want to point out that this answer is the product of my own investigati...
I want to make a simple 7MHz direct conversion SSB receiver in order to materialize some RF concepts I have been teaching myself lately. My question revolves around the mixer portion. I'm failing t...
It seems your question comes down to how to demodulate a SSB (single sideband) signal. Note that the single sideband is already the signal you want, just shifted by some fixed frequency. One way t...
This site isn't appropriate for telling you what to choose. We can, however, give you information on microprocessors versus microcontrollers. Microprocessors and microcontrollers are intended to d...
In addition to what Andy said (+1), the 350 mA AC figure is probably limited by power dissipation, and therefore temperature. It applies during normal forward operation where the secondary current...
CAN is asynchronous and, if you receive a string of consecutive zeros, the UART mechanism that turns raw CAN data into "a byte" might have to wait a great deal longer than 1 bit of data before it c...
Check out What are the most common causes of CAN bus communication errors? As stated there, CAN requires a clock accuracy of 1.58% or your CAN node is non-compliant. I would recommend to use <1...
It appears that a user's reputation score has disappeared from the top ribbon at the side of the user's login avatar/picture. Is this an intentional thing?
Since am interested in how a delta sigma modulator works, I need to know what is the difference between differential amplifier and differentiator if there is a difference of course.
A bit of a tangent, but in mcu firmwares, higher order filters can also be implemented directly with biquad sections. More work to implement vs single pole, but very reusable. Although to be honest...
Ripple doesn't need to be that high. I've done flyback supplies to power isolated sections quite a bit, using a pulse on demand scheme like yours. It's not hard to get the ripple down to ±50 mV. ...
I am eager to create a flyback converter for driving the high side MOSFET. Here is a snapshot of my work so far: 555 timer starts with generating ~100kHz 12V signal on Q1. Q2 is monitoring the v...
Answer to question 1: First, you need p-mos and not n-mos, as you are switching the circuit from the above. Second, it is better and simpler to parallelize mosfets for big current switches; this w...
I've got a broken roomba, I've tried new batteries and a working charger. The charger is supposed to output 20V-24W when the roomba is plugged in. the picture just shows how I'm measuring the pow...
Personally I wouldn't want another category (what you seem to mean by "section"). I also don't think this should be a code review site. However, asking for validation and advice on small and spec...
I think your grandfathers story is, shall we say, apocryphal. You should know that electrocution kills by stopping the heart (or causing fibrillation), and the heart must be kept from beating long...
What is your best suggestion for building a follower that would ideally satisfy the following spec: frequency: from 100 Hz (or lower) to 1 GHz input signal impedance: 1 Mohm input signal ampli...

I'm actually an algorithmic engineer, not an electronic engineer. But your question is extremely general, and valid for every field of engineering. Also, it obviously depends upon the human and tec...
More about the circuit The circuit is sensing (low side sensing for many reasons) current used to power up the lights with 28V(part of the schematics not shown here -> relay with LC filter ...
