A ideia deste projecto surgiu-me quando um dia estava a aceder remotamente ao meu PC para consultar uns trabalhos e imaginei que desta forma e ligando uma webcam poderia ver o que os meus gatos andariam a fazer quando sozinhos. No entanto precisava de algo mais pois a webcam pousada no topo do monitor não […]

EMI mains filters Schurter combined with an input AC connector will stop interference there, where it´s the most efficient – at the input. To be more precise, usually it´s the best to eliminate interference (EMI) already at a source of interference itself. But because there are a lot of disturbance sources in a common 230V

I try to have a few different projects on the go at any time — a big, long term project (like the Arducorder), a shorter-term fun project (like the Open Source CT scanner), and a bunch of smaller weekend or few-weekend project (like the open mini spectrometer). Having a few projects of varying time scales

I ordered this awesome N|Watch kit the other day, which requires some serious SMD hand-soldering skills. There’s always the easy alternative to use a reflow oven, but guess what, there is no stencil included (and no, I don’t have a paste dispenser). In a desperate need of a third hand (!) in order do a

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy
Scientists build thinnest-possible LEDs to be stronger, more energy efficient Continue Reading
miniLOG is a precise standalone voltage logger that save the data on a SD card. It has 4 basic analog channels: – one has 12bit resolution for voltage measurements, – two channels have 10bit resolution for voltage measurements and – one channel has 10 bit resolution for current measurements. Input voltage range is 0-25V and

Motivation Though I am a musician I don’t care for calling an expensive hi watt stereo my own. For years I have used a homebuilt stereo amplifier built around the TDA1554Q IC (basically just this chip in a nice box) and I am still very happy with the sound quality. This amp serves as a
