The future of IC design

Posted on 19 July, 201619 July, 2016 by mixos

R Colin Johnson @ edn.com discuss about the future of IC design and the different technologies that can extend Moore Law. Such technologies include 3D memories, superconducting, quantum, neuromorphic and photonic mixed-signal devices.

To celebrate 60 years of EDN, we’re looking into the future to predict what advancements will be made in IC Design in the next 60 years. By 2076 3-D room-temperature, superconducting, quantum, neuromorphic, and photonic mixed-signal devices will be the common denominator for all integrated circuit designs. Design tools will be so sophisticated that even novice designers will be able to mix and match these technologies into system-in-package designs that solve all application problems behind the scenes. Users will be so used to extensions to their innate brain capabilities that the technologies which perform the tasks will be taken for granted, leaving the engineering community—and its robotic assistants—on a unique echelon of society that actually understands how the world works.

Memory upgrade for ESP8266

Posted on 18 July, 201618 July, 2016 by mixos

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 of that? I would suggest only if you happen to have lots of ESP-01 units lying around – and I’ll bet quiet a lot of you do. As for the Sonoffs – well, put it this way, I just ordered another 10 chips!

Build an Arduino boost converter

Posted on 18 July, 201618 July, 2016 by mixos

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

Posted on 18 July, 201618 July, 2016 by mixos

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, 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

Posted on 18 July, 201618 July, 2016 by mixos

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

Posted on 18 July, 201618 July, 2016 by mixos

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

Posted on 18 July, 201618 July, 2016 by mixos

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!

Posted on 16 July, 2016 by mixos

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.

Arduino 50V digital Voltmeter using MAX7219

Posted on 16 July, 201616 July, 2016 by mixos

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 the measured voltage. This voltmeter can read only DC voltage.

TEA5767 FM Radio With Digital Volume control

Posted on 16 July, 201616 July, 2016 by mixos

niq_ro @ instructables.com show us how to build a FM radio using Arduino and TEA5767 module.

This version of FM radio with TEA5767 with digital volume use Arduino Uno development board instead Arduino Mega like in previous artilce.

Digital volume in 15 steps is made with MCP4261-502E/P dual digital potentiometer who work as real potentiometer (logarithmic style)…
