    Hello! Recently I discovered a mail for "Linus Tech Tips" with a message: "Hi Sa1tama, Emmi558 has sent you a message! Hey honey!) Open this!" First of all, I am wondering how does this 'Emmi558' has my E-mail address and second, can I report this user on this forum? Screenshot:

    Read this guide: Everything you need to know is here.

    What's the budget?
  4. Sa1tama
    Yeah, I know, but it is really hard for me to save money, plus, I noticed a really good deal on RX 580 and I don't want to miss it. BTW, the PSU I am using now is a ticking bomb, which might explode at any moment, so I really need to get a new one as fast as possible.

    I believe you are asking the specs of the computer; In that case: CPU: i5 3570 Mobo: Asus P8H61-M LX3 R2.0 Ram: HyperX DDR3 8x1gb 1866mhz GPU: GTX 1050 HDD: Toshiba 1TB I know that this parts don't require 600 watts, but I am planning to build a new rig with ryzen and an RX580, so I want to buy a good PSU now and use it in the future rig.

    Hello! As the title says, I am looking for a 600W PSU under 50USD. I don't want to get a used one from Ebay, so Amazon is the only choice. I looked and found this PSU: https://www.amazon.com/dp/B014W3EMAO/ref=twister_B07RBCD515?_encoding=UTF8&psc=1 Is this a good choice?

    Thanks for noticing that transistors are connected wrong and by there aren't gate drivers I meant that I could not find gate driver ICs.

    Hello! I have 2xG4PC50FD in half bridge configuration and a low power signal that needs to drive the IGBT which is connected to the primary coil. I looked everywhere and couldn't find any MOSFET driver ICs, so I want to make drivers from transistors (I have BD136 and BD139 in mind), but the problem is that the drivers need to operate at high frequency, from 100KHz to 400KHz and I don't know if this will work. Is this good enough?

    I checked the shipping info and turns out it doesn't ship here (literally no one ships to my country), so i would have to give a 3rd party company ~10USD to transport it. Alongside with price increase, it means that i will have to add 20USD to my budget, around 70% of the initial budget, so i don't think it's worth the hassle. But still, i deeply appreciate your suggestion, so thanks!

    Personally, i would wait a bit (july 7th) and buy a Ryzen 5 3600. It costs less than R7 2700x and it has waaaay better single core performance. If your mind is fixed, then i would recommend R7 2700X

    Hi! For my entire life i have been using a 5$ multimeter and i am sick of it, i want to throw that junk away, but sadly it's my only one. Because of this i have been saving up my pocket money (i haven't had lunch for a month) to get a new one. Yesterday i was searching multimeters on my local electronics shop website (dac.ge) when i came across this specific unit Sinometer DM88. I think it has all the functions i need for the time being. The Webpage: https://dac.ge/?en&act=product&prodid=2097 75GEL is around 28USD. I would love to hear your thoughts about it.

    Arduino makes the PWM signals which gets amplified by the MOSFET drivers to drive the Gates of IGBTs, which further amplifies the signal and is fed to the Primary Winding. A tesla coil basically is a High-Voltage transformer, which converts a couple dozen volts to 10s and 100s of thousand volts.
  13. Sa1tama
    To open Collectror-Emmiter path you need to feed power to Gate, but if you feed it normal music, nothing would happen. The solution is to create a PWM signal with variable duty cycle and frequency and feed it to the gate, that way, the H-Bridge acts as an amplifier and you can feed it directly to the Primary winding.

    Hi! I am almost done with building my tesla coil, the only thing that is left is a UI, but while coding i ran into a problem. I can't figure out how to identify songs and play them. I am using Arduino Mega 2560 with an LCD and an SD card module.Main code:int forward = 22;int back = 23;int Stop = 24;const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;#include <LiquidCrystal.h>#include "SD.h"#define SD_ChipSelectPin 53#include "TMRpcm.h"#include "SPI.h" // LCD RS pin to digital pin 12 // LCD Enable pin to digital pin 11 // LCD D4 pin to digital pin 5 // LCD D5 pin to digital pin 4 // LCD D6 pin to digital pin 3 // LCD D7 pin to digital pin 2 // LCD R/W pin to ground // LCD VSS pin to ground // LCD VCC pin to 5V // 10K resistor: // ends to +5V and ground // wiper to LCD VO pin (pin 3)//CS ---------------------->> 53//SCK ---------------------->> 13//MOSI -------------------->> 51//MISO--------------------->> 50//VCC --------------------->> +5v//GND--------------------->> Arduino's GroundLiquidCrystal lcd(rs, en, d4, d5, d6, d7);TMRpcm tmrpcm;void setup(){pinMode(forward, INPUT);pinMode(back, INPUT);pinMode(Stop, INPUT); lcd.begin(16, 2);tmrpcm.speakerPin=9;Serial.begin(9600);if(!SD.begin(SD_ChipSelectPin)){ Serial.println("SD fail"); return;}tmrpcm.setVolume(6);}void loop() { lcd.setCursor(0, 1); lcd.print("Now Playing:");}Thank you for reading, I really appreciate it.

    Hello! I am planning to buy an RX 480 and i'm wondering if i could combine 2 molex into 1 8pin and power it. Here is my psu:

    Hi! I just bought a mousepad on amazon. Amazon items don't ship to my country, so i use a third party company, that ships packages, but for that, i need a Tracking ID (code). The problem is: i can't find where it is. I tried googling it, but no luck there. Pls help. Thanks in advance!

    Audio Amp problem

    Sa1tama replied to Sa1tama's topic in Audio

    Well, that thing costs double the entire project. Also i live in a pretty bad place for electronics standpoint and https://store.edison.ge/ this website is the only place where i can get them

    I don't think overclocking a 4th gen i5 with B85 at 4.8ghz is a good idea. If it were me, i wouldn't do it, but if you are really itching to do it, then go for it, but keep an eye on the Temps and also, check the power rating of the mobo power connector on the PSU and make sure it can handle it

    Audio Amp problem

    Sa1tama posted a topic in Audio

    Hi! I am building a bluetooth speaker. I already bought necessary parts (BMS, Boost Converter...) and I am planning to use my old bluetooth headset as an HID device, but at the output it gives 5-9V and i am wondering if this Audio Amp can work with audio at this voltage. Audio Amp: https://www.amazon.com/gp/product/B01MG48YK0/ref=ask_ql_qh_dp_hza P.S I thought about finding where the Amp was on the headset, but couldn't find it. Thanks in advance!

    R7 2700 is a very good choice. Asus Prime X470-Pro is a solid Mobo with very good OC potential. (If you consider OC'ing in the future) Corsair H115i is a very silent and reliable AIO

To play on it from other locations, you can get a Raspberry Pi and with a bit of work and a good Wi-Fi (wired would be better) connection you can hook it up to a TV or a Monitor and it's ready to go. There are many youtube videos on remote game server with Raspberry Pi, but 90% of them are the same, so choose the highest rated tutorial. P.S This list doesn't contain a case, because it will be in a clothet or in a corner, so any cheap ATX case with descent airflow can do the job just fine.

    I suggest Lenovo Thinkstation s20. It has better CPU and a dedicated GPU, but like @ki8aras said, a cheap 240gb SSD will make everything way easier.

    i! i decided to make a class D audio amplifier for my bluetooth speaker project, but i have one question: In what config can I hook up a 20watt amp circuit to a dual 10 watt speakers? IC: TDA 2040 Speaker Resistance: 8ohm P.S It's my first project on this scale, so i am worrying that something might not work properly. Thanks in advance!

    Hello! I am looking for a good 3D printer under 200USD. I would like it to have atleast 12x12 cm print size. I am open to any suggestions.
  25. Sa1tama
    I like to build some amplifier circuits for some reason.I am currently trying to build a Class D amp for 80+80Watt stereo 6 ohm speakers (It's the most complicated thing i have ever tried to do)
