Pete show us how to upgrade your ESP8266 with 32Mbit memory chip. Some time ago I passed comment in here about converting an ESP-01 to 32Mb  (or 4MB).  And here it is in the flesh – a 32Mb ESP-01 – and also – at last – Sonoff Upgrades. Now, why would you want to do all...

Lucas Reed has a tutorial on how to build a boost converter using an Arduino. Have you ever needed to power a project that's not near an outlet? Have you needed to test using different voltages? Are you curious about analog circuits and power? Using Autodesk Circuits and a lead-acid...

Dziku show us how to configure HC-12 wireless module using AT commands. HC-12 are cheap 433MHz wireless serial port communication modules with a range up to 1800m in open space. Each costs about $5 when bought from China, and 2 of them can create wireless UART link that can be used,...

How electronics and neural systems can work together, amazing! Arthur English's group at Emory has developed a custom device that they have used for stimulating peripheral nerves optically in anesthetized mice using a standard optical fiber. The device is compact, rechargeable...

pighixxx.com has published Arduino UNO components in vector format. As promised, I publish the first components library to make pinouts. In particular it’s a library dedicated to Arduino Uno Boards, clones and related projects. The file contains several vector formats and any...

alex.puffer @ hackaday.io designed a nice PCB business card with onboard 555 timer IC. I decided I was tired of paper business cards, and wanted something more fun (and more impressive to show off). Having a PCB business card is also a perfect portable portfolio, showcasing my design...

educ8s.tv uploaded a new tutorial on their youtube channel. In this video we are going to learn how to send email using an ESP8266 based board like the Wemos D1. As you are going to find out it is very easy and it won't take us more than 10 minutes. Having a WiFi enabled board,...

M.Pugazhendi build a digital voltmeter using Arduino and MAX7219 display driver. The Arduino inbuilt 10 bit ADC, can be used for constructing / measuring the 0Volt to 50Volt Digital Volt Meter. Popular MAX7219 display driver, connected with Arduino Uno will be used for displaying...
