Introduction Running C++ Standard Library (std)-based projects on microcontrollers without...
Maker KB Sriram rebuilt a 1928 mechanical number sieve using 30 ATtiny412 chips and an RP2040, and the century-old math still checks out perfectly.
CircuitPython 11.0.0-alpha.1 adds RP2350 deep-sleep alarms, wake-on-pin support, and faster USB. Here's what changed and how to flash it this weekend.
Overclocked RP2350 Pushes 1080p: A Pico-class chip driving 1920x1080 over DVI, with 520 KB of RAM and no framebuffer. Here is the overclock, the scanline trick, and the wiring gotchas.
Esta es la segunda parte de la serie donde vuelvo a explorar los patrones embebidos más comunes. Esta...
This is the second part of the series re-exploring common embedded patterns. This one focuses on the...
Pocket Signal Generator AVR16EB28: An AVR16EB28, a 4.194304 MHz crystal and a spare pair of I/O lines make a 2 Hz to 33 MHz square-wave signal generator that fits in your pocket.
Someone Squeezed Generative AI: Five seconds, 520 KB of RAM and about a dollar of silicon: the RP2350 inside the Raspberry Pi Pico 2 is now generating 128x128 AI faces on-device.
Arduino's Zephyr RTOS Core: Arm killed MbedOS, so Arduino rebuilt on Zephyr. The 1.0.0 core adds Nicla Vision camera support, Zephyr 4.4.1, and VENTUNO Q silicon.
Add CircuitPython Watchdog So: A frozen microcontroller mid-demo is fixable in ten lines. The CircuitPython watchdog module lets your board detect its own hang and reset itself.
Arduboy's CHGame Rev0 is a $39 bare-board handheld: 48 MHz RISC-V, a 128x128 color LCD, and every GPIO pin broken out for hacking.
Upline Puts ATtiny85 Online: Upline is an open source serial protocol that gets an ATtiny85 or Arduino UNO on the web through a USB cable, using 4,060 bytes of flash and no Wi-Fi chip.
