Navigation Bar Fade Animation On Scrolling iOS | Xcode 9/ Swift 4
In this video i replicate a navigation bar animation requested by one of the viewer. The Navigation bar fades from transparent to a solid color and the navigation bar buttons fades from a solid white to red color. This is just a quick video too give you guys the concept on how to do it, But in a production app you will probably want to create a method to handle this animation.

Transparent Navigation Bar iOS | Xcode 9 / Swift 4
zhlédnutí 14KPřed 6 lety
In this short video, i will show you guys how to set the navigation bar to transparent in Xcode using Swift 4. Currently there is not way to set the navigation bar to transparent using storyboard. So, we will be creating a custom ui navigation controller class to achieve the transparent effect.
DIY Lab Bench Power Supply | Computer ATX Power Supply Conversion in under $10
zhlédnutí 149KPřed 7 lety
In this video I converted a Desktop/PC ATX power supply to a fixed lab bench power supply that can output -12v, 3.3v, 5v and 12v, and insane amount of current. The comoponents requierd for this ATX Power Supply Conversion are really inexpensive and with commonly used tools. I also added a USB port functionality to this ATX power Supply.

Buck Converter simulation using MATLAB SIMULINK / DC-DC Step Down converter
zhlédnutí 99KPřed 8 lety
A buck converter is a voltage step down and current step up converter. The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat and do not yield any current step up. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circui...
Boost Converter simulation using simulink MATLAB / DC-DC step up converter
zhlédnutí 194KPřed 8 lety
Boost converter simulation/modelling using simulink MATLAB. A boost converter (step-up converter) is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element, a capacitor, inductor, or the two in combination. Filter...
Bro... Where do you live
Thanks for the video, I have already implemented the boost converter and got the output similar to yours. But How can we smooth out the voltage waveform from the overshoots.
thank you👌👌👌👌👌
Porque en el puerto usb le conectaste 2 cables juntos
How do you plot the waveform for the inductor current
The best video and the original for of ATX power- supply to a bench power source
background music please?
I have a psu that worked, connected green to black and it turned on the fan. After cutting the wires, when I connect green to black, it spins the fan for half on sec and then it stops. And idea? The purple 5v has power for an led, but the other wires stop after half second
Good job 👍 keep it up
Superb bro!!1
Sorry ... Loading resistance is what for?
please make a video of design and simulation a buck converter for wind turbine... and put the link in reply
Thanks a lot helped me to do my semester assignment. Thanks a lott
So I got done with this project, and while it works, it's putting out some odd voltages. I'm getting 6.7, 10.7, and 26.7! About double what it should be putting out. Also the PSU's fan doesn't come on. I'm guessing it was probably junk before I got started. I'll run it til it conks out though, just can't use it for any precision stuff. Good thing I got it for free, just wish I had tested it out before putting the effort into the conversion. Any suggestions to what might have gone awry are welcome, whether it's the PSU or something I did to it.
the output is not the same
Can you make video how to make converter 48 vdc to 12 vdc topology forward.
salam saad brother can I talk to you ? I really need help in my project
Thank u a lot of, great video
Cool!
I think -12v is ground
no it is negative 12v
I'm getting voltage spikes, instead of the response you got.. could help me out with what is wrong with my output.... really appreciate your work
Thx u so much for this atx power supply ^ ^ I will build one as well : ) I have only one question for the USB output, would it not be better to use a Red 5V cable ??? I think the output would be stable 5V. Greetz Diego
You can use it but there always very high current on the red wire which are 5v they can deliver above 20amp easily if you connect something incorrectly you can blow that device up
WHAT IS MUSIC NAME PLEASE ?
The pc power stops for a period of time when the +,- is shorted.This is a little uncomfortable in the experiment
Thank you a lot. Please, can you share the simulation file with me ? my email : demnatidat@@t @t
What is the use of powergui?
Can you send me a map of it, thank you
Very nice tutorial. Thank you.
Bro i need this model kindly send me through email ahsanlone7866@gmail.com Plz i want to give presentation on pv system in which i need this model
Very nice! ;-) An opinion: Using the red wire to power your Power On light (Green LED) is fine... But if you had used the Grey wire, you would not only have confirmation that the power is On, you'd have confirmation that the unit is operating withing specs! Isn't that worth having? Anyway, something to think about. Cheers! ;-)
Using the project to power the label maker was a brilliant idea! ;-]
Appreciation from China, thanks a lot.
Great Video!
Good video. But keep your accent real. It sounds fake. But, if it is real then no problem.
Thanks, You're Awesome. It helped a lot!
I want to design a boost converter of input 5 v and output 12 v which mosfet should I used ? Should I use IRFZ44N and if yes then what values should I take for capacotor and inductor? please help
im just now watching this for the first time. I gotta say BRAVO.... You did a great job my good friend. Im bulding a custom benchtop power supply unit myself. Im having issues installing my LED power on lights. Like im not sure how or where I want to place them yet, but im going with the 3.3v and 12v outs and the 5v will be USB. I also had to put my fan on the outside top of the unit also. im also adding a 110v ac plug for my soldering iron. ill take a picture once fimished and upload it to my comment if it allows me to.. Thank you again my friend, you gave me some great ideas on mine and a few extra ideas.. Chase R from USA, Ohio.....
Great video! I would like to replicate this project but I am a novice, where can I find the schematic? Thank you kindly
hello sir.... can u make a video of three level boost converter.
Great
Hello, great tutorial, thank you very much, can you please also provide the tutorial for iOS 13, as Navigation Bar logic is changed there
Also looking for this.
what about the dropper resistors for the leds if you don't install any your leds will fry themselfs to death
can you do the simulation for double frequency buck converter?
works for xcode 11.1
Thank you
maybe this will help someone in the future create class or place it wherever you like, in this comment i create class file // // UINavigationBar.swift // MyCeisa // // Created by raditsan on 01/10/19. // Copyright © 2019 Raditsan. // import UIKit extension UINavigationBar { func transparentNavigationBar() { self.setBackgroundImage(UIImage(), for: .default) self.shadowImage = UIImage() self.isTranslucent = true } func removeTransparentNavigationBar() { self.setBackgroundImage(nil, for: .default) self.shadowImage = nil self.isTranslucent = false } } and place this function in the view controller that you want to be transparent the navigationbar override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(true) self.navigationController?.navigationBar.transparentNavigationBar() } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(true) self.navigationController?.navigationBar.removeTransparentNavigationBar() } and set view ex: (Imageview, scrollview, view etc) top constraint to be superview, not safe area. If you have a tableView and use ios11 add tableV.contentInsetAdjustmentBehavior = .never last try in iPhone 7 iOS 13.1 and work sory my bad english, like my comment, if help you 😁
Hi, great Video! I have one Problem. I want to change the Color of the UIBarButtonItem to darkGray instead of red but I have no idea how to do this, because darkGrays saturation is 0.
This is helpful. But, this is making whole application navigation bar as transparent. I need to make it only for single view controller. How to do that ?
very helpful, thanks
