DIY STM32 scope is simple, cheap and functional
Would you like to have a small digital oscilloscope? Do you have a spare BlackPill (STM32F401) board and TFT display lying around? [tvvlad1234] presents us with a simple and educational digital storage oscilloscope design that needs virtually no components for you to build one, and it's packed with features you'd expect from a self-respecting open source project . Plus, it can even stream data to your computer, in a format compatible with TekScope software!
It's hard to overshadow how this scope is easy to build, use, and hack. You really don't need a lot of parts, a protoboard will do, although you can also engrave or order your own PCBs. The frontend is very simple to find and assemble, a few op-amps and resistors are enough. So, having wired the LCD display and three push buttons to your BlackPill, you're golden.
Of course, the simple interface gives an input range of -3.3V to 3.3V, but as you might guess, this is exactly the kind of project where you can change resistors and even upgrade them later. Are you a bit lost in how oscilloscopes work? [tvvlad1234] also has an explanation for you!
This build could easily take an honorary "temporary-turned-permanent" place on your bench, thanks to its McGyver-esque qualities. It's also, most likely, a better scope than the red "solder kits" we saw online. All in all, it's a strong contender in the realm of "simple and powerful DIY scope", before this we've seen one built with an Arduino Nano and one with a Pi Pico.
