principles and practices


Final Proyect
"Smart Table for emergency situations"

coding

The idea of this smart table is to bring back communications and basics need to an emergency situation like earthquakes and tsunamis. This folding table could map the territory and the magnitude of the catastrophe bringing communications again with the built-in mesh networking antennas. With a network of tables, you could have constant feedback of differents spots. With this network, victims can talk each other (could be an IRC chat) and inform the needs, so organizations like the Red Cross can improve the distribution of aid in an effective and organized way.

coding

As the network is based on a Wifi Mesh all the affected can connect to it and warn the authorities and the neighborhood, for example, a missing or some specific need of this part of the territory. Also, it would be used as an internal collaboration tool. It has solar panels and some of the basic medical assistance. These tables are operated by volunteers that can handle the operations of the tables.

coding

Would be something like a network of Swiss Army knives, distributed support centers that can restore connectivity to report the disaster in real time. The biggest problem of large catastrophes is that the territory is fragmented and interrupted. This could help to mitigate the damage of emergencies, is intended mainly for people who must remain in the disaster area for security and reconstruction. On the other hand, there are people who simply has nowhere to go and prefer to be in their neighborhoods instead of going to the reception areas



First Final proyect idea
"Adding hotwire and extruder to existing CNC Router frame"

We use different machines for differents process, each work we make in fablabs have it´s own optimum machine, like 3D print when you want to build a complex part or mill a piece of metal. Here I´m trying to integrate the different process for a specific task like surfboards profiling, so you can take advantage of simultaneous tools in the same part machining.

coding

This machine wants to use a single XYZ frame, the idea is to understand and integrate the electronics, control and software. The first step would be to integrate the CNC router and the hotwire. The hotwire could replace the roughing toolpath, removing material faster. After that a parallel termination only in necessary places. This is thought to adapt an existing CNC router. Would be sufficient to add two axes for hotwire in the X-arm and use the Y axis of the router.

project management


Firts time meeting Git

Learning git was nice, with practice is very comprehensive, is powerfull and reliable. For the first test, I made a GitHub site with terminal in OSX. These are the commands I mostly use.

coding

Terminal commands used


  • ls ,List Item
  • ls -l , More Info
  • ls -a , Hidden files
  • cd , go to home folder
  • cd / , Go to the root folder
  • cd .. ,Go to the upper folder
  • cd , Go back
  • ls -F , Show all the folder in the computer including Network

GIT commands used


  • git add --all , Add to the list of changes
  • git commit -m "Initial commit" , Commit Message
  • git push -u origin master ,Upload my last version
coding

First, I used an HTML template, then I modified the CSS using the editor Sublime Text 3. Here you can see the original template so you can see the changes.

Description:

The assignment for this week was to setup our Webpage and upload it to GitLab, also, we present a concept of what could be our final project. UPDATE: I have changed the final project to IT project that could be useful in emergencies situations.
