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.
We are proud to announce that eLab will organize its first workshop. In this workshop we will show you how to convert an ATX power supply unit (PSU) from an old computer, into a very simple Lab power supply with the most common voltages (-12V, -5V, 3.3V, 5V and 12V). Very useful for electronic beginners who are in need of a power source for designing, building and testing circuits. Each participant will have the opportunity of acquiring basic knowledge about an ATX PSU and put it to the test converting their own power supply provided by eLab.
Power over Ethernet or PoE, is the technology used for power transmission in network equipment, via network UTP cable, together with data. PoE is useful in situations when we want to connect network devices that are far away from a power source. In this situation we take advantage of the Ethernet cable, because there are 4 pairs of wires, but for the majority of networks, only 2 pairs are used for data transmission. PoE uses 2 unused twisted pairs, for electrical transmission needed to power the device. (more…)
In eLab’s third week, we’ve continued the projects we had previously started:
- eLab’s logo is almost finished, the circuit is complete, there is only some adjusts left to do to some LEDs. Soon it’ll be visible to everyone above our lab’s door.
- The RFID reader for our entry system control is still in development, it is an ambitious project and has been offering us some difficulties, although we have started to obtain some visible results.
In our second week, after the opening of eLab, several small projects were initiated:
- Desk lamps were installed in each work station to allow better conditions for our activities.
- An acrylic eLab’s logo was made for LEDs to be added later, with the purpose of identifying our Lab from the exterior.
- The RFID card reader project for the entry control system was started this week. The circuit was designed and the components identified.
- A heating system was also initiated, as a project for acrylic bending, through recycled halogen light bulbs from old scanners.
Welcome to eLab’s blog! This will be the first of many posts about the projects developed by the Electrical and Electronics Engineering students, ex-students of the Superior Institute of Engineering in the University of the Algarve and also from other members.
