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.
