The LM317 Adjustable Voltage Regulator
The LM317 chip is an adjustable linear voltage regulator that you can use to provide power to your electronics project. It has a range of 1.25 to 37 volts and offers a maximum current output of 1.5 amperes.
Display modules for Electronic projects
After writing an article about batteries, I thought it’d be great to write something about displays/screens that are available for electronic projects — especially small ones before going into detail on each of them at a later article.
Batteries for your Electronic Projects
Recent miniaturization of electronic components not only bring smaller projects but also less power hungry ones. We now have pocket computers that do in seconds what room-sized computers do in a day — powered by batteries to boot.
ESP8266 – this chip changed everything
In my opinion, the ESP8266 actually gave birth to the Internet of Things (IoT). The inclusion of an integrated WiFi electronics changed everything — it gave the ability for single chip computers like the ESP8266 to connect and communicate with other computers.
Power Supply for the Solderless Breadboard
Electronics projects that I want to do most of the time need either a 5V or 3.3V supply so I decided to buy one of those off-the-shelf Breadboard power supply.
Helping Hands when Soldering
When you’re trying to solder things together, it really helps to have more than just two helping hands besides my own… and with parts getting smaller the magnifying glass (or an iPhone camera) is your friend
The Solderless Breadboard that work flawlessly
A basic thing that is called a solderless breadboard is where it all begins. A tool that allows different electronic components to be connected together and perform in synchrony to do different tasks. It can be something as simple as turning on/off a light.
ESP32 H.A.N.D. Project Update
I’ve recently started an ESP32 project whose objective is to automate some of the tasks in my home. Since my last update on my web site, I’ve made some additions and changes to the project. To get updated on what’s new read the rest of the article.
Cheap Car Vacuum Cleaner
Working on turning this cheap (less than $2) 12-volt car vacuum cleaner into a lithium battery-powered cordless version…
ESP32 H.A.N.D. Project
When the ESP8266, the predecessor to the ESP32, came out, I was hoping for a chip with lots of I/Os but more importantly something that has both WiFi and Bluetooth built into the chip.
It happened — Espressif launched the ESP32 chip and this got me very excited. At last, a small, versatile and powerful chip that supports a lot of the, in my opinion, needed features and functions that makes a great chip for both electronic hobbyists and commercial applications. Read more
