eLab Hackerspace GSM Access Control System

Hi! ­čÖé As you may already know, I am one of the founders of eLab Hackerspace, in Faro, Portugal. In case you didn’t read it, I have made a post about the birth of eLab Hackerspace before. It is located inside the Institute of Engineering of the University of the Algarve and its members are…




Infante robots – an educational robotics system

┬á Hi! Today I’ll show you a project that started as a challenge that I have accepted and turned out to be one of the most challenging projects I have ever done. K6 professor Bruna Carmo wanted to do some research on educational robotics for her Master Thesis but couldn’t find an affordable educational robotics…




High torque encoded DC motors for robots from car window motors

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…




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…




Making a Siemens C55 Data Cable

Hi! Recently I’ve been developing a GSM access control system for┬áeLab Hackerspace using an old Siemens C55 cell phone and, as such, I needed a data cable to connect it to a PIC microcontroller. I searched on ebay for one but it turned out that they were a little expensive and I began thinking about…




Turning the Raspberry Pi into a Wireless Access Point

Hi! Following my latest posts on how to get started with the Raspberry Pi “headless mode” and Using Bluetooth with the Raspberry Pi now I’ll show how to turn the Raspberry Pi into a Wireless Access Point. Most of this post follows what is described here┬ábut I added a few more steps. Moreover, I ran…




Experimenting with vacuum molding

Hi there! This post is about a really simple way of making plastic parts for your projects. Have you ever heard of vacuum molding? It’s a method to make a plastic mold of a piece by using heat and suction from a vacuum cleaner. You can easily replicate what I’m going to show you. You…




CNC Controller Board v2

As I said previously, I have been slowly developing my second CNC Machine, TheMaker2. To control the new CNC machine I developed a new board based on a PIC16LF877A since the L297‘s that I used on the first CNC controller board that I designed can be quite expensive here in Portugal and I had some…




Homemade CNC: TheMaker2

Hi! As I previously said in my first post about my first┬áHomemade CNC: TheMaker1, I was slowly developing a bigger, faster (didn’t accomplish this part yet) and more robust CNC. Well, the development phase has finally come to an end and it is finally ready! ­čśÇ In order to build a more rigid structure I…




Adding an external power supply to a cheap USB hub

Hi again! In this post I’m going to show you how to add an external power supply to a cheap USB hub. ­čÖé ┬á ┬á I’ve been running some experiments with two Logitech Quickcam for Notebooks Pro and the Raspberry Pi┬áand unfortunately I haven’t been getting any good results. I can’t get many fps and…
