Devices

ESP32 Cheap Yellow Display

Fork at ~/personal/ESP32-Cheap-Yellow-Display. Own sketches live separately in ~/personal/experiments/cyd/:

• Leetcode/ — daily question on the display, see CYD LeetCode daily
• TouchTest/ — touch calibration, start here when the panel misbehaves

ESP32 accountability tracker

Separate device from the CYD. Three signals on one display: a large number for total active days (long-term accountability), colour for today’s status, and a separate weekly indicator.

ONVIF camera

~/personal/experiments/camera/ — Python. ONVIF for discovery/control, WebRTC out via aiortc + MediaRelay, OpenCV for frames. Not deployed; run locally.

Home Assistant

Lives in the dash repo, at home.namanvashistha.com. Two things bite:

• Pinned to 2026.6. :stable (2026.7, Python 3.14) deadlocks at boot — ImportExecutor hangs, 0% CPU, never binds 8123.
• Bridge networking, so it can join the caddy network. Costs mDNS/DHCP discovery — add integrations by IP or cloud. A Zigbee/Z-Wave dongle would need devices: passthrough and probably host networking.

Raspberry Pi

~/personal/pi/backup_2024_07_18/ is a card image dump, not a live checkout. Boot partition .dtbs cover Pi 2B through Zero 2 W.
