In case you had been to level to a single system accountable for a lot of Hackaday’s early success, it is perhaps the Arduino Uno. The little board from an Italian college with its straightforward to make use of dev setting modified microcontroller hacking endlessly, and whereas it’s now very a lot outdated hat, its shadow lies lengthy throughout single board computing.
Simply in case you thought there wasn’t rather more life in that outdated AVR in 2026, alongside comes [Arc1011], with KernelUNO, describing itself a “A light-weight RAM-based shell for Arduino UNO with filesystem simulation, {hardware} management, and interactive shell“. It’s an OS on your Arduino, of kinds.
For flashing it to your Uno, you get a shell with some acquainted wanting filesystem and system instructions, the power to write down to information although no editor, and a set of instructions to regulate pins. It’s extraordinarily primary, however you may see the potential.
If we had been to take a position as to how this would possibly turn into extra helpful then maybe it would contain a extra everlasting filesystem maybe on a flash chip. If potential, the power to run script information containing a listing of instructions would even be very good. Although we’re guessing that possibly the explanation these options should not in place lies within the meager specs of an ATmega328, for which we will’t blame the developer in any respect. Even when it may possibly’t be prolonged on this manner although, it’s nonetheless a cool undertaking.
We’ve got to return fairly some time, however this isn’t the primary time one thing like this has appeared on these pages.
