I am making a boost converter following this Tutorial but I don't have the exact MOSFET. I have 2 motherboards laying around and they have some MOSFETs on them some of the names are: P3055, K3918,6670AL(datasheet inserted). There are high switching speeds but the datasheets don't have the max...
No doubt a High-quality metal construction Design with Flexible silicone nozzle for better seal for suction. Majority of the buyers keeps on complaining about the issue while ejecting the waste solder. Solder get stuck in the silicone nozzle and they find it difficult to unclog it. I believe...
Good afternoon to everybody. First post over here!
I am working on the estimation of junction temperature from top case temperature measurement.
I have seen that manufacturers avoid the characterizing the molding this resistance which is crutial for this purpose.
From now on I will take...
A begineer here. I am making a simple DC motor based car. I am using the following components,
Two 12v DC motor (1000RPM, No-Load Current: 70mA (max) )
L239D Motor Driver
Arduino D1 board
Eight 3.7v 3800mah Li Battery (4 batteries for each motor )
My doubt is,
1. I want to run...
Hi, I just have solved one of the bjt common emitter question below.
However, I'm curious that how can I additionally find those things below:
1) Input and Output Impedance
2) AC Gain
Here is the example and my hand draw solution. However, the question only asked to find Vout/Vin...
I am planning to buy the l298n motor driver. I am just trying to make sure I know how to calculate the output current of the l298 motor driver. Output current depends on the load? I measured both the input current and the input voltage to the motor. According to ohm's law, the internal...
I bought DIY amplifier board.
And now I am trying to find what I did wrong. It can work for about 2 seconds and then sound dissappear.
But power stays on, and LED is glowing
I connected 24 volt toroid to start the board. In description it says that circuit is designed for 12 to 36 AC...
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"
Which would you say is...
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...
