The University of Algarve has just organized the 3rd edition of the UAlg Summer Courses. These offer the young students insight over many different areas like art & design, sciences, communications, sports, economy, management & tourism, engineering, medicine and sociology.
eLab Hackerspace had the opportunity to contribute to the event with a DIY PCB fabrication workshop as well as a small project presentation. Continue reading UAlg Summer Courses 2015
As an application of our previous post, here is a project where we used our PicPgm to program a PIC18F4550 micro-controller.
This little project is an example of a simple audio application using a PIC micro-controller. Using only digital inputs and outputs, we developed this simple piano/synthesizer with an 8 bit kind of style: Continue reading PianoPIC
After another workshop in eLab, we can be proud for organizing another successful event. In this second workshop, all the participants had the opportunity to learn about some of the most common methods used for the homemade manufacture of printed circuit boards. A total of 5 methods of transferring the circuitry to the board were demonstrated: UV light exposure with acetate sheet and greaseproof paper, toner transfer to a magazine sheet and to foil and finally by applying a negative dry film. Also, 2 corrosion processes were demonstrated: through iron perchlorate and through a mixture of muriatic acid and hydrogen peroxide.

Following the last publication about PCB (printed circuit board) manufacture, we present another useful project. The corrosion with iron perchloride, is a slow speed process, but we can accelerate the process, by agitating regularly the solution. To do this, we created a simple device, able to make an automatic PCB agitator, using an old DVD desktop drive. Continue reading PCB Automatic Agitator
We announce that eLab will organize its second workshop next Wednesday, November 21st at 4.30 pm. This workshop will be about the different methods for making PCBs (printed circuit boards), where each participant will have the opportunity to learn about some common methods and make its own PCB.

In the middle of a project we are developing, we felt the need to create some PCBs (printed circuit boards) so we used the opportunity to prepare our next workshop. We experimented and got to know a new method for creating PCBs, a method usually known as toner transfer.
