Maker Perspective

For Beginners/ Aspiring Makers Arduino UNO is my recommendation, very straight forward and very easy to get started.

Tech Specifications

• Powerd by ATmega328P
• 14 Digital I/O Pin, which 6 provide PWM output
• 6 Analog Input Pins
• 16 MHz Clock
• 32 KB (ATmega328P) Flash Memory
• 2 KB SRAM
• 1KB EEPROM

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. The board is equipped with sets of digital and analogue input/output pins that may be interfaced to various expansion boards and other circuits.

The main thing I loved Arduino is the community and peripherals That supported, also the Shields. these are boards that can be plugged on top of the Arduino PCB extending its capabilities. The different shields follow the same philosophy as the original toolkit: they are easy to mount and cheap to produce.

Another one is the IDE, The Arduino Integrated Development Environment is a cross-platform application that is written in functions from C and C++. It is used to write and upload programs to Arduino compatible boards, but also, with the help of 3rd party cores, other vendor development boards.

The Original Arduino Uno cost around $21, but you can also get clones even cheaper, but I recommend to buy original to support there mission and vision.

There are some recommendations if you're into hackathons or quick prototype/POC.

ESP32/ESP8266

Others who have experience with the Arduino ecosystem, I suggest the Esperssif ESP8266 or ESP32 Low-cost WiFi and BLE* development platform, which is highly supported by the Arduino ecosystem. That means you can reuse many of the Arduino functions and libraries out of the box.

Particle Photon

The Photon is a $19 tiny Wi-Fi IoT device for creating connected projects and products for the Internet of Things. It's easy to use, it's powerful, and it's connected to the cloud. The board is powered by a Cypress Wi-Fi chip alongside a powerful STM32 ARM Cortex M3 microcontroller.

It's very easy to quickstart, also super easy to connect with particle cloud if you project involve Cloud and Connectivity.

If you need more computing and processing power you can check the Raspberry Pi and BeagleBoard Single Board Computers

Raspberry Pi

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries Since the aim is to teach kids about physical computing and computer science, the documentation and getting started is very straight forward and simple.

There are different models of Raspberry Pi SBC(Single Board Computer) and the latest one is Raspberry Pi 4 Model B which cost starts from $35. There is also lighter version called PiZero which cost around $5

Website: https://www.raspberrypi.org/

BeagleBoard

The BeagleBoard is a low-power open-source single-board computer produced by Texas Instruments in association with Digi-Key and Newark element14. The BeagleBoard was also designed with open source software development in mind and as a way of demonstrating the Texas Instrument's OMAP3530 system-on-a-chip.

If you are a beginner and want to get started the embedded Linux development, then you need to checkout beagleboard series single-board computer.

The list is not over yet, I'll share more thought on the thread as a followup.

Sharing a tip that can be very useful when working with Raspberry pi GPIO, The GPIO Pinout is designed to be both a quick and interactive reference to the Raspberry Pi GPIO pins, plus a comprehensive guide to your Raspberry Pi's GPIO interfaces. It also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs.

This Pinout.xyz gather useful information about the Raspberry Pi GPIO interface and add-on boards and invite board manufacturers to produce their own "overlay" files which describe which pins their Pi add-ons use. It's very handy when comes quick prototyping.

Hi @ZeeZa ,

You need to build a custom board with the ESP32 SoC and the MPU6050 IMU, right?

first, you need to select appropriate ESP32 SoC from the wide variety of model, after that using the datasheet find out the minimum configuration circuit for the SoC and add the MPU6050 module. that's all you need. the most tricky part is the minimum configuration circuit.

Fab Foundation has started a GitLab repository for the Fab Lab Network for #Covid-19 projects HERE. Please note that in order to edit the repository you need to have a fablabs.io or GitHub account. This repository includes links to many of the incredible projects and efforts being organized around the world, as well as projects of the Fab Lab Network in development. Use this as both a resource and as a central place to sync around projects, aligning with CBA, Fab Foundation and with other gurus from the fab network and beyond.

Hi @Geethesh, If you are building simple POC (Proof of concept ) or Quick prototype then the HC-05 is enough with the ATtiny.

• For the ATtiny45 minimum circuit you only need one Pull up resistor for Reset, and one Filter capacitor between VCC and ground and you also need to populate ICSP pins for programming

• You also need only two external componts HC-05 and Buzzer .
  

• In the this project we did't require any external oscillator , the internal 8mhz should be fine .

Overview

One of the key concepts in electronics is the printed circuit board or PCB. It's so fundamental that people often forget to explain what a PCB is. This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world.

Here we are using Sparkfun PCB Basic tutorials, and after that, we have some ToDO that you need to complete.

ToDo:

• Find the Annular ring, Drill hit, Finger, Mouse bites, Pad, Silkscreen, Slot on the PCB you used (ex: Arduino Uno, Relay) and Document it (Docs, Github, MakerGram..etc)
• List out PCB designing Softwares
• Download and Install Autodesk Eagle

Balena team announced the Fold for Covid project, a simple way for anyone to contribute spare compute power from home to support the research of COVID-19 treatments.

What is Fold for Covid, and how does it help?

The Fold for Covid project aims to make it easy to donate spare compute capacity to support COVID-19 research with a few simple steps. This effort contributes to the Rosetta@Home project, led by the Baker Laboratory at the University of Washington, which uses distributed computing to help scientists and doctors find potential treatments for COVID-19.

Your contributions help researchers look for proteins that bind to the famous “spike” protein on COVID-19. By finding these binding proteins, doctors hope to develop medicines that prevent the virus from entering healthy cells.

Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!

Update: Found that SPEC 3SP_CO_1000 Package 110-102 have 0 to 1,000 ppm sensitivity range and < 100 ppb reseultion, if anyone worked with the sensor let me know. Thanks.

@vishnumaiea

@vishnumaiea I agree, they did an incredible job in the making of this product and, it looks like a perfect board for the maker/student/artist who wants to build project and learn stuff, they released all the docs, SDK, kit's even a book too.

I believe the perfect MCU depends on the application and price range so that actually works well in RP2040 latest for hobby maker I think, I not stating this is perfect MCU but it can make a big effect in maker market like Arduino UNO.

@vishnumaiea said in The Raspberry Pi Pico:

Since RPi is from UK they must have also been able to make a better deal with ARM, which is also from UK
