Video of Episode 2 of Portuguese Makers Hangouts

Hi everyone :)
As I said in my last post, I have been invited to participate in Episode 2 of the Portuguese Makers Hangouts. It was on the 21st of May at 22:00 (Lisbon time). In case you weren't able to watch it  live, here's the full hangout. It's in portuguese but you'll still be able to see the projects that were shown. I hope you like it! :) .

Portuguese Makers Hangout - Episode 2

Hi! :)
Recently I've been invited to participate in Episode 2 of the Portuguese Makers Hangouts. Quoting from  the webpage, "the purpose of these Hangouts is to gather the Portuguese Makers and get the world to know about their talents and their projects". They are used to share experiences and create contents around the best of the DIY/Make scene in our country.

From 3 to 5 participants are invited for each hangout and their goal is to show the audience their creations, talk about the problems and challenges they had while building them and their lessons learned. Live demos are usually provided :).
Anything that mixes creativity and art with technology counts. A robot, a quadcopter, a cool gadget, a 3D printer, a new technique or material, anything that comes out of the inventor's obsession to create things will do.
All the hangouts are recorded, saved, and made available on as many channels as possible. Currently, the Portuguese Makers Community is aiming to do an Hangout every month, but this might change (for the best).
In this hangout I'll be showing and talking about my homemade CNCs, specially TheMaker2, and some robotics stuff.
In this hangout there will also be participating the Portuguese Makers Nuno Correia showing his printrbot and João Frazão showing Ziphius (that recently won the Engadget's Insert Coin contest) and some other projects.

The live feed will begin on the 21st of May, at 22:00 Lisbon Time. You can confirm your attendance to the event here on G+. Share this event with everyone that may be interested :).
If you wish, you can see the 1st Episode of the Portuguese Makers Hangout here.
You can also join the Portuguese Makers community here.

Take care! :)

Hi! :)
This short post follows my recent post on How to Download Complete Albums from Picasa in Ubuntu. A blog reader asked on the blog's facebook page on how could he download all the photos and after a short research I found the solution.

To download the entire photo set from a specific user you'll need to have two programs installed: Mozilla Firefox and the Firefox extension DownthemAll. In a short way, here's what you have to do:
  1. Install Mozilla Firefox;
  2. Install the Firefox extension DownthemAll;
  3. Open the following link in Firefox:
    You'll have to replace the "USERNAME" part with the correct username. The last parameter of the RSS link, "1000", means that the feed will have up to 1000 photos. If you have more pictures than that, just change it to a value that suits your needs.
  4. Right click anywhere in the page, select DownThemAll and then the Links tab. The Pictures and Media stuff are just thumbnails.
  5. Make sure the JPEG images filter is selected, choose the destination folder and click Start
After this process you should have the selected user's complete photo set being downloaded into your hard drive. Easy, isn't it? :)

Take care! :)

Hi! As I mentioned in my latest post on how to make Tiny Encoders for DC Motors, some time ago I went to a junkyard to salvage two powerful high torque DC motors from car window lifting systems to use in a robot. I had to take my own tools and dismantle the doors from an old Renault Laguna myself  to get the motors and then managed to negotiate with the seller to buy both motors for 25€, which I think was quite cheap.

Tiny Encoders for DC motors

Hi again! Today I'll show you a small part of a project that I did a long time ago and, due to some changes of plans I didn't end up using. Anyway, maybe this small project might come up handy for you.
Some time ago I went to a junkyard to salvage two powerful high torque DC motors from car window lifting systems to use in a robot and had to make some encoders to put in them. The space where I could put them was really small so I had to find really small sensors and design a PCB for them in Kicad.
The sensors that I used were Vishay's TCUT1300 IR Transmissive Sensor with photo-transistor output. Following the sensor's datasheet I designed a small board (10x8mm) that would fit in the space that I had available.
