Hello guys, i need your help to understand how the ESD monitors do work, i mean how do they detect if an operator is wearing or not the ESD wrist strap. I'd be very grateful if someone knows the answer. Thank you in advance.

Hello! I am a computer science and AI student, but I am getting into hardware. Over the last few weeks, I have become rather adept at designing circuits and PCBs (I might have audited a couple of courses but that doesn't matter... right?). I have designed my own version of a maker board --...

I have currently designed a powerr converter, with a single phase transformer which operates at >200kHz. The design goal was to create a converter that increases power density, by minimzing the size of the passive components, namely the transformer and the output storage capacitors, which are...

Hi Everyone, my DT project includes an inductive charger. I would like to build a circuit that when a voltage is received from the inductive charger (9Vdc in ~5Vdc out) one LED blinks then after 10s it remains constant. Then turns off when voltage is stopped. I’m not entirely sure how to go...

Hello everyone, Im currently working on a small LED-Strip Panel. Im using an MT3608 DC-DC Step Up to convert my 5V from an USB powerbank to 12V in order to Power the LEDs. The LEDs draw around 0.7 amps. However, the powerbank wont stay turned on and if I connect the micro USB cable from the...

I have been looking through the famous app note on Average Current Mode Control by L. Dixon,https://e2echina.ti.com/cfs-file/__key/telligent-evolution-components-attachments/13-112-00-00-00-00-44-35/Average-Current-Mode-Control-of-Switching-Power-Supplies.pdf. He gives many examples on how to...

Circuit diagram- here Okay so we need to calculate V which is Vb1e1 I guess. If we can get Ic1 then Vb1e1=R5*Ic1 if I'm correct. We have B=100 so Ic1=B*Ib1 ie 100Ib1. If we are to apply KVL, how do we go about it? What is the overall voltage in all the loops? Also, is it correct to use voltage...

Hi everyone! I don't know if this is the place to ask Control Theory related questions, but it's for modelling a power electronics circuit so I thought I could at least try. I have to design a grid connected inverter in Simulink using the PLECS toolbox and I ran into some problems when designing...

Hi everybody! Hope you're good! :) I'm strugglin since some days on that nice muscial tool. I've replaced some faulty switches. Replaced them with new one from Mouser. Sadly I've managed to hurt some VIAS connecting both side of the board. Luckilly enough this is just 2 layer board (top/bottom)...

what else? Ways to Power a Project Here are some of the most common methods used for powering a project: USB Power Variable DC Benchtop Power Supply AC to DC Wall Adapter (like a computer or laptop would use) Batteries

Hi guys ! First i'm new member here with you , and i hope you guys help me with my power supply kit problem: Like most people , i have problem with this kit wich is i get -0.45v when the V and A pot are fully anti-clockwise and i get only 5.1V when the V and A are fully clockwise. I checked...
