content: DC to DC buck converters is a famous topology in the electronic and a widely used circuit in electronic devices. A buck converter steps down the input voltage while it increases the output current. In this article/video, I have discussed a DC to DC buck converter that can be used effectively as a switching power supply. The output voltage and current are adjustable: 1.25V to 30V and 10mA to 6A (continuous). The power supply supports the constant voltage (CV) and constant current (CC) features. Two LEDs demonstrate the CV and CC status. The circuit is compact and both sides of the PCB have been used to mount the components.To design the schematic and PCB, I used Altium Designer 21, also the SamacSys component libraries (Altium plugin) to install the missing schematic symbols/PCB footprints. To get high-quality fabricated PCB boards, I sent the Gerbers to PCBWay.To test the circuit, I used the power analysis feature of the Siglent SDS2102X Plus oscilloscope (or SDS1104X-E), Siglent SDL1020X-E DC Load, and Siglent SDM3045X multimeter. Isn’t cool, so let’s get started!SpecificationsInput Voltage: 8V to 35VDCOutput Voltage: 1.25V to 32VDCOutput Current (continuous): 10mA to 6AOutput Current (short period): 7A to 8AOutput Noise (no load): 6mVrms (9mVp-p)Output Noise (6A load): 7mVrms (85mVp-p)Output Noise (6A load, 16P-average): 50mVp-pEfficiency: up to 96%

content: Don't think it would work as the signal of interest must be split and experience almost exactly the same path channel characteristics. Delays, time skew, amplitude and phase characteristics need to be identical for the cross-correlation to work. Any variation would appear uncorrelated and tend to average out along with each channel phase noise, and not contribute to the eventual "signal" growth during averaging.Best,

content: It would be interesting to try in practice how well one can calibrate against skew, amplitude, phase, etc. types of differences that exist between the two paths of the signal (talking about the setup used in the cross correlation method shown at minute 35:35 in the video).Intuition tells me that the most important would be the stability of the parameters. If the differences (between the two paths of the signal) are stable in time, then it might be possible to identify the exact values of those differences (at calibration time, like it is done for example in a VNA calibration) then apply corrections to the sampled signal.

content: DC to DC converters are quite popular among electronic enthusiasts and are widely used within the industry. There are three major types of non-isolated DC to DC converters: buck, boost, and buck-boost. In this article/video, I used three major components such as the famous UC3843 chip, a power Schottky diode, and an N-Channel Mosfet to design a compact DC to DC boost converter. The input voltage could be as low as 9V that makes it suitable for a variety of applications, such as 12V to 18V conversion to power a laptop computer using a single 12V battery.I used Altium Designer 21 and SamacSys component libraries to design the schematic and PCB. The PCBs have been fabricated by the PCBWay in the green solder mask. Also, I examined the noise figure of the circuit using the Siglent SDS2102X Plus/SDS1104X-E oscilloscope and Siglent SDM3045X multimeter. So let’s get started!

content: Infrared remote controllers are everywhere around us. The majority of home appliances are controlled using infrared remote controls. In this article/video, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads). So we can use this feature in a variety of applications without buying a new IR remote control and expensive hardware, such as turning ON/OFF the lights, opening/closing the curtains, ... etc. I have used an ATTiny85 microcontroller as the heart of the circuit. The device can record up to three IR codes in the EEPROM memory and switch 3 separate devices. Each relay can handle the currents up to 10A. The load switching mechanism (momentary ON/OFF, toggling, .. etc) can be programmed by the user.I used Altium Designer 21.4.1 and the SamacSys component libraries (SamacSys Altium Plugin) to design the Schematic and PCB. I also used the Siglent SDS2102X Plus/SDS1104X-E to analyze the IR signals.The device works stable and reacts well to the transmitted IR signals. So let’s get started and build this puppy!

content: I have an old injection molding machine that had pretty ancient controls and decided to make a "modern" controller for this machine. I chose to use embedded rust as it's much safer than C++. I've done plenty of C++ work in the past, and so I know how easy it is to get memory issues. Embedded rust mostly avoids those by design. So I wanted to give it a try. This is my second project using embedded Rust. So far I'm really enjoying using Rust. I'm also experimenting with using a cooperative multitasking system called Embassy, which is looking very promising. Oh, and I'm using an STM32F303 Nucleo board right now.I also wanted to have a touch screen. Being somewhat lazy (this is a hobby project and I have too many of them), I decided to go with a Nextion display. I'm documenting the process on my YouTube channel as I go along. My plan is to make this a kit I will sell (I probably won't sell very many) mainly so I can get back into PCB design and use my new to me Neoden 4 (I got a very good deal on one).

content: Power supplies are one of the most popular topics in electronics. There are two major types of regulated power supply: linear and switching. Both power supply types introduce some advantages and disadvantages, however, a linear power supply offers better line and load regulation figures and it handles lower noise at the output, specifically when the power supply is adjustable and the output is under load; although its efficiency is lower than a switching power supply. In this article/video, I introduced an adjustable 30V-4A linear power supply that provides constant voltage and constant current adjustment. The output noise of the power supply is low and has measured using the power analysis feature of the Siglent SDS2102X Plus oscilloscope. All component packages are through-hole, so you don’t need any special tool for soldering.

Cheap USB to UART (RS232/Serial) Converter Using Microchip MCP2200 - Page 1

timestamp: February 27, 2021, 02:47:43 pm
content: Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips, so the USB port is converted to a virtual COM port on the computer. The initial thought of many designers is to use FTDI chips to do the USB to UART conversion. There is nothing wrong with FTDI chips, however, they are expensive. In this article/video, I introduced a cheap USB to UART converter module that uses the MCP2200 chip from Microchip. The converter supports both 3.3V and 5V serial logic levels and uses three LED indicators for power connection, data transmission, and data reception.The module supports the serial CTS and RTS pins, also six GPIOs that can be used for direct controlling of connected devices. The serial data of the module has been examined and decoded using the UART decoding feature of the Siglent SDS2102X Plus oscilloscope. So let’s get started!

content: OMG, soldering iron covered with some black soot. Tip is oxidized, yet you are mercilessly poking PCB with it for many seconds, while trying to melt something. Instead of just tinning it. Unscrewing Phillips screws with flat head of phase tester, which of course is already broken because of this. Mega cringe.

Plus, nowadays, I don't solder something thus didn't find need to change it.as for phillips screws, hmmm... my philips screwdrivers are all smaller than this one thus I used the flat one. and no it wasn't broken because of this but rather since it is cheap plastic case didn't tolerate my extra violence in the past. I had other screwdrivers though.I don't know from your post if you hated the video or just love the hardcoreness of it xD. your explanation is welcome brother.Side note: don't over-judge your fellow engineering brother over mere soldering violence xD

content: FM transmitters/receivers are among the top favorite circuits of any electronic enthusiast. In this article/video, I have introduced a complete digital FM receiver design that has equipped with an LCD screen and three push-buttons. It can search for the FM signals from 76MHz to 108MHz manually and automatically (Scan mode). The signal strength is also displayed as a bar graph on the LCD screen. The output sound is amplified by a 3W+3W Class-D stereo amplifier that handles high-quality and strong enough audio power. As a controller, I have used the cheap and popular Arduino-Nano board. So let’s get started!

content: It is difficult to achieve good quality with the help of an smoothing-iron, it is unlikely to achieve FR4 without a lot of experience.Somewhat more complicated, but much better quality can be obtained using a photoresist.And to fix the toner after transfer, you can wet it with acetone.

timestamp: September 21, 2020, 09:07:01 am
content: I've never achieved good results using plain paper. It seems to me that the paper fibers tend to get stuck on the toner more easily, and that leads to worse results than using glossy paper. In my experience, at least.Also, when etching, I let the board float face down on top of the ferric chloride solution, so I don't need to keep stirring it.I've never tried the acetone method. Seems interesting.

It is similar to the one that serves as the base for self-adhesive paper.But the iron technology is ugly, very simple boards. Even using a photoresist will allow you to do better and apply a mask and silkscreen. And all this is for enthusiastic people who like the process itself, for whom it is a vacation. Industrial production of boards from Chinese friends is already very cheap.

I'm an electronics hobbyist myself who took a 25 year break then returned to electronics as it was required when I switched careers and jobs. I've found it's obviously changed a lot in 25 years but the job I do is repairing 1980's and 1990's era electronic display boards so I'm right at home.Anyway with the lockdown I've been furloughed since March so I thought I'd start building up my Youtube channel and electronics blog. I don't have a workshop and all work has to be done on the kitchen worktop so it's by no means a professional channel. I use a phone camera (however it's pretty decent and supports 4K) so videos are a bit let's say unprofessional but it's all I have at the moment. It consists of arduino projects I've made, teardowns of odd electronics mainly avionics and military hardware and general rants etc.YouTube channelhttps://www.youtube.com/channel/UC-teLYZizQoOEJiQiu0QTzQElectronics Bloghttps://www.adrian-smith31.co.uk/blogIf anyone wants to take a look and let me know what they think I'd appreciate it.

Why?I simply cannot believe that not a single Youtuber apart from Linus (who is not even in the Youtube gossip space) is talking about this, it seems impossible.Search results being suppressed or something?And yes, Linus is obviously right, he's doing to hide his old content to protect his business, which is fine of course. I'm just interest in why I can't find a single video talking about it?
