Diagnosing Computer Motherboard Power and Voltages

In this video I show how to properly test for proper voltages and amperage on a HP Pavillion 23 model H017C. Properly testing your power adapter can save you time and headache. You can go down a bad road when misdiagnosing voltage measurements due to faulty power adapters. Visit my shop in Savannah GA http://www.TimsComputerFix.net

Circuit Skills: Power Supply

The requisite starting point for anything electronic - you won't get much blinking, buzzing, or processing done without a power supply! Learn more here: http://makezine.com/video/circuit-skills-power-supply/

Buck converter vs. linear voltage regulator - practical comparison

In this video I'm comparing in practice a buck converter with LM7805 linear voltage regulator. Two driver boards from old hard drives are used as a dummy load to check efficiency and temperature of the buck converter and linear voltage regulator. I'm presenting pros and cons of both devices. There are 2 mistakes in my calculations: 1. 5:02 - 5:08 - correct calculations should be: (12V - 5V) x 0.42A = 2.94W 2. 5:17 - 5:23 - correct calculations should be: (12V - 5V) x 0.22A = 1.54W I double checked everything, but I should have triple checked. I'm sorry for my mistake.

Wiring a new 240 volt circuit

Running a wire from a new breaker in the breaker panel to a workshop area in the basement for a 240 volt circuit for my table saw and bandsaw http://woodgears.ca/wiring/240volt_circuit.html

Have you seen this Cool Electronics Testing Tool?

Identify all the loose parts in your parts bin. Is that transistor a PNP or NPN? What's the volatge drop and capacitance of that LED? This tester will show you with colored graphics Multi-function Tester TC-1 This is where I bought mine; I'm sure they're available on ebay etc. https://www.banggood.com/DANIU-3_5inch-Colorful-Display-Multi-functional-TFT-Backlight-Transistor-Tester-p-1083042.html?rmmds=search Music Fireworks by Jahzzar is licensed under a Attribution-ShareAlike 3.0 International License. http://freemusicarchive.org/music/Jahzzar/Travellers_Guide/Fireworks
