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
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.
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.
Working on turning this cheap (less than $2) 12-volt car vacuum cleaner into a lithium battery-powered cordless version…
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
Finished rewiring my #ESP32 project on two breadboards. Should now be able to add the still missing elements like the motion sensor when they arrive.
My #ESP32 project is getting crowded on one breadboard. Would have to rewire the thing on two breadboards. More about it starting next month on igerry.com
If you find the #ESP8266 cool for creating Internet of Thing projects, you should watch this video of the tiniest Mac Plus running on an #ESP32 chip https://www.youtube.com/watch?v=mBiQgLlgcnA #IoT
Comparing the USB Tester to my old multimeters — digital meters are smaller and smarter.
I’ve started to taking out from storage some of my electronic related tools to start on some personal projects. Lately, I’ve had the need to measure voltages and currents on USB devices and it’s a pain to setup circuits just to test them.
After, searching the Internet to find a solution, I’ve found out about this small USB tester that allows easy measurement of a USB device’s voltage and current. It also has other features that allows a user to measure other parameters like milli-ampere-hours and the elapse time. This became very useful, for instance, in cases where I want to find out the charging capacities of lithium batteries.
