Read an SPS30 with a Pico, preserve the gap during fan cleaning, and reject CRC, status or stale-data failures without presenting cached values as new.
Compare two water-probe polarities with a finite Pico capture, retain raw ADC readings, and calculate a signed late-window proxy without claiming total charge.
Configure a timed LIS3DH magnitude condition, qualify the latch on a supported board, and service its source without turning merged interrupts into a fall count.
Acquire new TSL2591 raw exposures after gain and integration changes, reject either clipped channel, and track the limits of host-observed freshness.
Connect the exact three-volt MLX90614 to Pico, verify PEC and error flags, and investigate why target size, distance, emissivity and package temperature affect an apparent reading.
Read raw SGP40 gas counts on Pico with CRC, self-test and a controlled cadence. Keep compensation assumptions, conditioning and unimplemented concentration/index outputs explicit.
Read an exact AS5600 module with Pico, qualify magnet status and cross the zero boundary. Learn why gaps and unseen turns invalidate an accumulated angle.
Build a defined 25kHz fan command through a 5 V buffer. Keep motor power separate, release the output on cleanup and distinguish commanded duty from measured RPM.
Use an advisory local lock before claiming a Pi LED. Test two-process exclusion, normal cleanup, forced death and why deleting a lock file can break ownership.
Run a cancellable five-second light beside a heartbeat. Explore modular deadlines, settled presses, missed-edge coalescing and an explicit late-loop stop.
Explore these do-it-yourself project kits. Check the selected option, included parts and instructions on each offer.
