30W solar Raspberry Pi server: off-grid setup
Build a self-sufficient solar-powered Raspberry Pi server with a 30W solar panel, 12.8V LiFePO4 battery, and charge controller for off-grid operation.
Gemma 4 architecture explained: per-layer embeddings, shared KV cache, and dual RoPE
Gemma 4 uses per-layer embeddings, a shared KV cache to cut memory, and dual RoPE for mixed local-global attention. Activates 3.8B of 26B params.
Home Assistant smart irrigation: local control, $25-89 hardware
Build a smart garden irrigation system with Home Assistant, a rain sensor, and automations. No subscriptions, full local control, $25-89 in parts.
PCIe bifurcation: add 4 NVMe drives for $25-50 per adapter
PCIe bifurcation splits one x16 slot into four x4 lanes, so you can add up to four NVMe drives on a $25 adapter at full per-drive bandwidth.
Python Memory Optimization: 50-80% Reduction with memray
Profile and optimize Python memory with memray, tracemalloc, and objgraph. Covers leak detection, generators, __slots__, and cutting peak use.
