Play with "Play with Docker" from your terminal!

A simple, interactive and fun playground to learn Docker.

Play with Docker (PWD) is a Docker playground which allows users to run Docker commands in a web browser.

 https://labs.play-with-docker.com

I will describe how to use your terminal in Ubuntu with openssh to play with "Play with Docker " :)

How to build a server for spatial information

How to build a server for spatial information

In this post I gather all the tutorials needed to setup a server for managing spatial information with open source software.

Analysis of linear soft potentiometer and conductive rubber cord stretch sensor

I done some test to see the repeatability and the accuracy of the sensors it's not the best method but it is good to give you an approximation.

3D Printer

Finally I managed to finish this project and it is working perfectly much better than I expected...
Despite the fact that nothing is lined properly it prints very accurately.





As friends say: "it looks like flintstones printer!!!" :)

A printer made mostly from scrap parts, old printers and other materials, but it can print new amazing things!

Weight scale Updated. A very old project came to life again...

Weight scale with Arduino and HX711 module (max 5kg)

Data Science with python

Advice for beginners:
Always use a environment manager the most common are Conda and Virtualenv, I personally use Virtualenv but most people prefer Conda.

Most common packages you will need for data science is pandas and numpy.
If you use python 3 install a package with pip3 package_name.
Take a look at TensorFlow for machine learning!.

Schematics

CNC puzzle!!

Just for fun! CNC puzzle!


Well I was building my CNC I came across with a problem. I had already connected the end stops for each axis separately as always ON switches and then I figured out that the controller has the end stops pins connected together for each axis (the - and the + as one). So I had to figure out how to connect them without changing the wiring..

So here is the game!..

Simple LED flasher

I made this simple LED flasher as a safety blinker for my bicycle.
This circuit it only consists of two transistors, two capacitors and four resistors. You can control the flash rate by changing the size of the resistors or the capacitors.

Wiring

You have to connect the 5 wires of the ICSP of each arduino as shown in the picture below

Preliminary assessment of natural hazards in Monemvasia Municipality (Greece)

This is a preliminary study of natural hazards in Monemvasia municipality. The study aims to identify the areas of the Municipality, which occurs inundation, landslide, seismic risk or risk of fire starting. Both the residential, and industrial development of recent years in increasing the risk and weigh the potential environmental, social and economic consequences of a potential incident. Analyzed and processed all available data to produce maps with risk indicators for each of the aforementioned risks individually, an attempt is made to forecast the consequences and made recommendations for the prevention against natural disasters and managing probability event.
