What Passive Components Do You Need? | Workbench Wednesdays #28

Wed, 09 Sep 2020 21:41:00 +0000

Whether you are just getting started in electronics or you have boxes of parts, it is good to know what are the most critical parts to have in your kit. James asked the element 14 community for what they considered to be essential passive components like resistors, capacitors, switches, wires, and even diodes. In this video, he consolidated their puts and explains what to think about when buying these parts for your kit.

Instrument Basics: LCR Meter | Workbench Wednesdays #22

Wed, 01 Apr 2020 23:31:00 +0000

Learn how to use an LCR meter, such as the Tenma 72-10465, to measure reactive components. An LCR meter uses an AC signal at different frequencies to characterize capacitors, inductors, and even resistors. They can also provide impedance measurements. These include phase angle, ESR, quality factor, and dissipation factor. You can even use the 72-10465 to sort components by their tolerance range.

5 Voltage divider circuits that go beyond dividing

Wed, 23 Aug 2017 13:19:15 +0000

Hey Newsletter Readers: Looking for Best Resistor Sorting Method? My Bad! Here are some ideas of what you can do with the humble voltage divider. This elementary circuit has a few inventive uses. To be upfront, one of these uses is NOT as a voltage regulator. If you need a voltage regulated, get a voltage regulator! At some point or another, I’ve built all five of these voltage divider circuits. For me, the voltage level shifter is the most common.

Best Sorting Resistors Method

Wed, 12 Apr 2017 13:00:51 +0000

When you buy a grab bag of components, you might need to tackle sorting resistors. Here’s how I sorted some bags of random resistor assortments last week. Objectives Then method I use for sorting resistors achieves these objectives: Fewer Bins. It doesn’t take long to create a large matrix of resistor values. My resistor sorting method is relatively compact. Quick to find. When I’m building up a circuit, I don’t want to spend time sorting through a pile. Once I know the value I need, I find a single package and then look for a single color band. Works with 4-band and 5-band resistors. Let me be upfront: I *hate* 5-band resistor color codes. While the 5th ring is supposed to be slightly offset, or wider, or a different type of color; it doesn’t matter. It’s nearly impossible to tell read a 5-band resistor color code when they are in a pile. However, using my method for sorting resistors, it doesn’t matter if I’m looking at a 4-band or 5-band resistor. I can immediately identify the resistor value. Based on #3 alone, you might be wondering what is the fantastic method (and how much will it cost to get it!) Here’s the basics of my method for sorting resistors. (For FREE!)

Chuck Norris On Pull-Up Resistors

Think you can do without Pull-Up Resistors? Only Chuck Norris doesn’t need them.

AddOhms #8: LEDs and Current Limiting Resistors

Mon, 10 Feb 2014 12:00:49 +0000

The idea for AddOhms #8 has been around for quite some time. I’m always trying to find ways to explain why current limiting resistors are necessary. So while working in the shop one day, I decided to play with some LEDs and a bench-power supply. Then I decided to record what happens.

Reverse Resistor Color Code Generator

The other night I happened to see a tweet come across my twitter stream from Joe Walnes (@joewalnes) about a resistor color code tool he created. You can find it at the clever domain resisto.rs. Type in a value and see what the proper color code should be. This is great for when you need to go searching through a pile of resistors and want to make sure you have the code right.
