Mihir Shah has designed many a PCB in his time. However, when working through the development process, he grew tired of the messy, antiquated methods of communicating design data with his team. Annotating photos is slow and cumbersome, while sending board design files requires everyone to use the same software and be up to speed. […]

There was a time when an intercom was simply a pair of boxes with speakers joined by a couple of wires, with an audio amplifier somewhere in the mix. But intercoms have like everything else joined the digital age, so those two wires now carry a load of other functionality as digital signalling. [Aaron Christophel]

A bench oscilloscope is one of the most invaluable tools in the hardware hacker’s arsenal, but even the slimmest digital models are a bit large to be part of your everyday electronic carry. Sure you could throw one of those cheap pocket scopes in your bag, but what if there was an even easier way

Oscilloscope displays have come a long way since the round phosphor-coated CRTs that adorned laboratories of old. Most modern scopes ship with huge, high-definition touch screens that, while beautiful, certainly lack a bit of the character that classic scopes brought to the bench. It’s a good thing that hackers like [bitluni] are around to help

Arguably the biggest advantage of the Arduino platform is its ease of use, especially when compared to what microcontroller development looked like before the introduction of the open source board and its associated software development environment. All you need to do is download the IDE for your platform, plug in your Arduino, and you can

A basic open-source multi-GHz sampling oscilloscope for experimenters on a budget. Still a work-in-progress, with key pieces on separate PCBs, but showing bandwidths in the 7-8 GHz range with >= 100 GSa/s equivalent-time sampling, and around 500 k comparisons/second real time. So far. Note: this writeup is somewhat out of date, as it doesn’t cover

A common problem that often comes up when working with micro controllers, is running out of IO for all the input the projects requires. So I came up with this solution that allows a user to have up to 4096 button inputs using only 4 lines of IO. This is done by sending out data

Oscilloscopes were once commonly called CROs, for the fact that they relied on cathode ray tubes for display. Since then, technology has moved quickly, and oscilloscopes these days almost entirely rely on modern screens like LCDs. However, [lonesoulsurfer] went a different route with this fun DIY build, creating an oscilloscope with a low-resolution LED display. Yes,
