How to Build a PoC – “كيفية بناء “إثبات المفهوم

بسم الله الرحمن الرحيم

Step 1: Proof of Concept

A proof of concept is an approach to build a “THING” to check a certain idea in order to confirm that it is feasible, viable, applicable in practice and really meets a particular business need.

In a nutshell,

  • It addresses the following question: Can a product be built or not?
  • It describes the idea, functionality, and feasibility of a product.

Step 2: Prototyping

The prototype has the design, appearance, functions, and other components of the product theoretically visualized in the POC project.

Step 3: Learning

Step 4: Drawing Ideas and Playing With Scenes

The following tools help in making a rough drawing of the ideas or to create scenarios or scenes of the concept.

Step 5: High Level Tools

Step 6: From the Shelf (Limited Resources Platforms)

Step 7: From the Shelf (for Great Projects )

  • Pc equivalent board: https://projects.raspberrypi.org/en
  • Node-RED began as a proof-of-concept for visualising and manipulating mappings between MQTT topics, quickly became a much more general tool that could be easily extended in any direction. :https://nodered.org/about/

Step 8: Components Suppliers

Step 9: Open Hardware Designers

Step 10: Self Designed Prototypes

Step 11: Pcb Manufacturing

Remotely Controlled Vehicule – مركبة تحكم عن بعد

بسم الله الرحمن الرحيم

Step 1: Introduction

This design is the complementary part of our Yet Another Remote Controller” Board at https://www.instructables.com/id/Yet-Another-Remot….

This article describes the design of a Remotely Controlled vehicle according to the following requirements:

  • Simple design
  • Sonars – Ultrasonic Sensor HC-SR04
  • Servo motor
  • Remotely controlled by RF 2.4 GHZ and Bluetooth
  • MPU6050 a 3-axis Gyroscope with Micro Electro Mechanical System(MEMS) technology
  • Oled display
  • 2 Potentiometers for parameters adjustments
  • Blue Led
  • Buzzer
  • Battery driven

Step 2: Schematics

Step 3: BOM ( Bill of Materials )

Step 4: Pcb

Step 5: 3D View

Step 6: Assembly

Step 7: Coding

Step 8: Enjoy

A 25 seconds video is embedded to show the use case.

Antenna Design (Clone) – (تصميم الهوائي(نسخ

بسم الله الرحمن الرحيم

Step 1: Introduction

Antenna design is not an easy task.

To simplify things, we will CLONE the well known chineese module 2.4 GHZ nRF24L01+.

The nRF24L01+ is a single chip [2.400 – 2.4835GHz] transceiver suitable for ultra low power wireless applications.

Step 2: Documentation

Nordic semiconducteur provides a reference design for the nRF24L01+ chip. It prodives the recommended components too.

Cypress provides an extremely useful article to design a 2.4GHZ antenna.

Our PCB footprint is based on Cypress guidelines.

Step 3: PCB Antenna Footprint

I just followed the Cypress guidelines to draw the footprint. Becareful with dimensions (mils not mm).

Step 4: Schematics

I just reproduced the Nordic Semiconductor reference design in Kicad editor.

Step 5: PCB Design

Kicad is used to route this simple board.

Step 6: PCB Assembly

Becareful with the soldering iron.

Be patient.

Step 7: Enjoy

To test the newly designed Module with its integrated antenna, we used our “Yet Another Remote Controller Board“. Our module fits and replaces the totally cloned chineese equivalent.

Digital Ruler – المسطرة الرقمية

بسم الله الرحمن الرحيم

This article is a demonstration of the use of the 128×32 pixels OLED.

OLED displays are bright, lightweight and visible under a wide range of lighting conditions.

We will show you how to hook up an OLED display to the ATTINY85 µController and build a Digital ruler.

Step 1: Components Sourcing

Just a few components are needed to build this simple gadget.

Step 2: Schematics

As always, Kicad is used to edit the schematics.

Step 3: Pcb Design

A simple board means easy routing with Kicad.

Step 4: Pcb Assembly

Becareful with the soldering iron. Be patient.

Step 5: Arduino Sketch

The code is simplified since it uses the open source library for OLEDs “Tiny4kOLED”.

Step 6: Enjoy

A 30 seconds video is embedded to test the gadget.
