There’s many a time when you want to connect a white LED to a microcontroller operating from a 3 V supply voltage. Unfortunately, this doesn’t work and your nice white LED only lights up feebly or not at all. Why does it work perfectly with red and green LEDs, but not with white? A bit […]

You’ve got to love the aesthetics of dystopian cyberpunk video games, where all the technology looks like it’s cobbled together from cast-off bits of the old world’s remains. Kudos go to those who attempt to recreate these virtual props and bring them into the real world, but our highest praise goes to those who not

The Broadcom® AFBR-S4N33C013 is a single silicon photomultiplier (SiPM) used for ultra-sensitive precision measurement of single photons. The active area is 3.0 × 3.0 mm2. The high packing density of the single chips is achieved using through-silicon-via (TSV) technology and a chip-sized package (CSP). Larger areas can be covered by tiling multiple AFBR-S4N33C013 CSPs almost without

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers that work in much the same way. [mircemk] decided to whip up a digital compass to demonstrate the value of these parts. The build uses
Robert Book is a tinkerer by nature and works at Silicon Valley Bank with Ian McCutcheon, a geek by nature. One day they were talking and Robert shared his big problem: his son Jerry, who suffers from Muscular Dystrophy, couldn’t use a keyboard anymore but loved to play computer games. Jerry could only be able to
