Workshop summary: Making PCBs

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.

Workshop – Power Supplies

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.
