Practical Electronics – Hacking My Shark Cordless Vacuum Project, Part 1

In mid-2011 I purchased a Shark SV75SP 14 cordless hand-held vacuum cleaner for small messes. The unit is shown in the picture below.

The batteries on the Shark lasted for about 10 minutes before they were drained and I was constantly recharging the thing. Worse yet, the instructions said to charge it for 16 hours (that’s a long time!). [Read more…] about Practical Electronics – Hacking My Shark Cordless Vacuum Project, Part 1

Digital to Analog Converters – An Introductory Tutorial

2 Comments

At first, I was going to write about the analog to digital converter (ADC). I decided to write about the digital to analog converter instead.

Why?

I started gathering information about ADCs. Then it hit me: digital to analog converters (or DACs) are often part of analog to digital converters.

So, the topic this time will be the types of digital to analog converters and a bit (sorry for the pun) on how they work. [Read more…] about Digital to Analog Converters – An Introductory Tutorial

An Introduction to Resistor Color Code

6 Comments

This post is going to be another short one that covers some basics but may also be a good review for electronics veterans alike.

The topic is resistor color code.

If you’re just starting in electronics you don’t want to miss this one as it will discuss one of the most basic yet important things you need to know.

Now, I know some of you may be thinking something like “…yeah, but there are resistor color code calculators online so why bother?”

A Tutorial On Logic Gates

4 Comments

Logic gates (or just gates) are one of most basic building blocks for computers and all things digital.

Like most things in electronics, I could write a large book concerning all things logic gate-related. Some of these things include truth tables, Boolean algebra, combinational logic, DeMorgan’s theorems and more.

This tutorial on logic gates is meant to be an introduction to the various gates and how they work. [Read more…] about A Tutorial On Logic Gates
