If you have not been trained to work with high voltage then have an amp technician service your amp. See more tube amplifier safety info here.We'll start with the amplifier layout diagram. If things get too cluttered you can refer back up to this clean diagram. The guitar input jacks ...
Laptop keyboards use a flat flexible cable (FFC) that is often manufactured as a flexible printed circuit (FPC). This cable connects to all the key switches in an array of rows and columns as shown above. The keyboard controller drives each row low, one at a time while reading the column...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
the 1.2A*0.7 would equal 0.84A. In order to check this I uploaded a simple code that sends continuous logic high to the Step pin (so that we can better notice the current) and connected my meter in
You will need some supplies to build one of your own. Below are links to where you can find the parts on Amazon. ■ An Arduino Nano(x1):https://geni.us/ArduinoNanoV3 ■ A 5m roll of WS2812B LEDS which has 60 LED’s a meter:https://geni.us/5mWS2812B60m ...
Ohm’s Law, and Selecting the Right Resistors Placing a resistor in your circuit when you’re using an LED is always a good idea, but how do we know which one to use? Too much resistance, and the LED will appear very dim or won’t light at all. Too little resistance,...
Mains power insulation of a motor is tested using a high voltage leak test and the test can’t be performed with a volt-ohm meter. You can unplug the tool turn the switch on and test for the resistance from mains power to frame and it should be a value higher than the meter can re...
I can test and measure, but I don't understand which circuitry in a transmitter can make it incompatible with a properly tuned antenna. I have to guess that the output resonance has changed (no longer likes the 50ohm unbalance line)...but I don't know how to test for that. ...
Everywhere I look I see mentions of the 1-8 method with that picture as an example which designates pins 1 and 5. I've also found another article which explains that you want to pull the Chip Select pin to high to prevent the chip from being read. You achieve this by shorting th...
If that is done here it is in the cutout, before the meter, and you shouldn't even be able to remove the cover. « Last Edit: January 16, 2020, 07:06:54 pm by Monkeh » Logged tkamiya Super Contributor Posts: 2178 Country: Re: How is Neutral Wire Neutral in Mains ...
