What do you do when you’re a starving student and you need a 400 MHz logic analyzer for your digital circuit investigations? As [nanofix] shows in a recent video, you find one that’s available as an open hardware project and build it yourself.

The project, aptly named LogicAnalyzer was developed by [Dr. Gusman] a few years back, and has actually graced these pages in the past. In the video below, [nanofix] concentrates on the mechanics of actually putting the board together with a focus on soldering. The back of the build is the Raspberry Pi Pico 2 and the TXU0104 level shifters.

The Hazard 3 RISC-V cores on the RP2350 were designed by Raspberry Pi’s own Luke Wren in his spare time – and as they’re open source, you can download the design files yourself and start poking around in the very same chip that will eventually be in use on millions of units out in the wild. As Eben Upton puts it: “In adding Hazard3 to RP2350, we’re aiming to give software developers a chance to experiment with the RISC-V architecture in a stable, well-supported environment, and to popularise Hazard3 as a clean, open core, suitable for verbatim use in other devices, or as a basis for further development.” Luke’s reflections first appeared in issue 145 of The MagPi.
