Hi; Is it possible for a lithium battery, whether Li-ion or Lipo, to resiste a temperature of 90 up to 100 ° C in a period that does not exceed 3 minutes?
knowing that its working temperature range indicated in its datasheet is 60 ° C.
thank you for any information given
I currently have a custom PCB design using the PIC16F1937-CN. The custom circuit gives an output voltage via the usb to an external device. I would like to charge my circuits battery with the same usb port which is currently not the case. It has another port for charging the device.
So I'm 15 and have been doing electronics for about 2 years now as a hobby and I want to go further and try learn more about this amazing subject.
I'm torn between 2 books however:
"The Art of Electronics: 3rd Edition"
"Practical Electronics for Inventors"

I recently bought myself a HVGEN10AC v3.1 to drive my Cockroft-Walton Voltage Multiplier. At 24V input it can produce 10kVpp. I want to connect it to my multiplier but the transformer only has 1 HV-Output and the Voltage Multiplier needs 2. As you've probably already noticed I'm very new...
I'm new to microcontroller programming. I would like to ask how do I display multiple keys on my LCD display. An example is I want to show "123456". Below is the codes I'm using. I am using PIC18F4520 and this is my LCD datasheet. Thanks in advance!
I need help in to generate feedback for fan regulator to the controller.
1. AC Fan require 1 phase Ac supply (230VAC/50Hz)
2. Controller require DC voltage in range of 0 to 3V3
3. System is able to support all type regulator, there different type's...
I am building Solar Guitar™ prototype, an eco-friendly, self-sustained musical instrument solely powered by the Sun:
10-15 watt, 2 speaker stereo guitar amplifier with reverb/chorus/delay/overdrive will be installed into the guitar’s body...
I have a RF Long wave transmitter (broadcasts only to 10ft diamater). However there are no rf amplifier products available on the market to purchase. Does anyone know where I can get schematics to build one? (I know what transformers, diodes, transistors, capacitors, and resistors...
I have to transfer 24 VDC to 21 devices which is 1000 ft apart. Is it possible to transfer 24 VDC to such a long distance?
This 24 VDC is coming from SMPS. Does the current/power rating matter in this case?
And how can I calculate total voltage drop at the end (If there is any)?. All...
I am designing a transformer for a high voltage converter. The topology is a push-pull converter. My method is to have a 200V primary generate 4x750V secondary windings, each feeding a voltage multiplier to generate 1500V. Then connect these in series and generate the final 6kV.
So far I have...
I am in the process of designing an interlock for two operations.
1. Operated by Manual Switch
2. Remotely through an Automatic Switch (Can't be controlled Manually)
If user turns manual switch then operation should start. (In this case, if someone activates automatic switch it should...
I am having trouble with a problem. I would like to derive a formula for some parameters (resonance frequency, Quality factor, Wcl and Wch)
Normally, you will use a general second-order function for a second-order RLC circuit (which is easy to derive). However, my circuit is much more...
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...
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...
