Build an Arduino boost converter

FTZHW7QIPZPGFQ9.MEDIUM

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 battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V.

HC-12 433MHz wireless serial communication module configuration

HC-12-433MHz-wireless-module-1024x651

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, for example, to transfer telemetry data from UAV. Or drive IoT device. Or connect sensors. Or whatever else one can think of.

Optogenetic hardware setup

OLYMPUS DIGITAL CAMERA

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 battery-operated, and controlled either manually or by computer using an analog input.

Arduino UNO Components library

Components_uno

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 component can be expanded (For example the Atmega328 with and without socket)

PCB Business Card

7445701462922543413

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 and layout skills.

This project will span the first and all future iterations of my personal PCB business card. Ver. 1 starts off slowly with a pilfered 555 schematic but moving forward, things should get more interesting!

Arduino ESP8266 Tutorial: Send an email easily with your Wemos D1 board using a PHP script!

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, like the ESP8266 enable us to do many more things. I wanted to learn how to send emails from the Wemos Board in order to get reports from my projects to my email account easily. As you are going to find out, it is very easy!

I have built a simple project in order to demonstrate what I mean. I have connected a DHT22 temperature and humidity sensor, and when the project boots up, it measures the temperature and the humidity and sends the data to my email address! This functionality can be very useful in some projects. As you are going to find out is very easy add such functionality in your Arduino projects. But let’s see how to build this project.

Able to fit in the palm of your hand and provided with several changeable tips, the 3DSimo Mini allows you to 3D print using one of close to a dozen different materials as well as solder, burn, and cut foam.

“We created the 3DSimo Mini to be the ultimate creator’s tool,” says David Paskevic, CEO of 3DSimo. “It is more than a 3D printing pen. Immediate uses include extensions for burning, foam cutting, and soldering. In the future, we will incorporate additional functionality to the pen, such as drilling, making it a practical tool for creators of any skill set. The Mini is a tool that can be used for all creative projects.”
