The Waveshare PocketTerm35 turns a Raspberry Pi 5 into a 3.5-inch handheld retro gaming terminal — but out of the box Batocera doesn't understand its gaming keys, the Esc key won't exit games, and the M.2 board's fan is loud. This guide documents a complete, r...

DNS APUs — architecture Two PC Engines APU2 boards in a 1U dual-slot 19" chassis are the household recursive DNS. Clients do not pick a box. DHCP (and the core intercept of rogue DNS) hands out 10.53.53.53. Each APU puts that address on lo and FRR advertises ...

Anycast self-heal FRR on each APU advertises 10.53.53.53/32 as a stub of lo. The core therefore load-shares onto whatever is currently advertised, not “whatever has OSPF Full”. If an APU cannot actually serve DNS, it must take that address off lo itself. Th...

MikroTik fabric — architecture The household network is three physically separate L2 islands, not one big switch. Production RSTP roots on the CCR2116. Management (vlan89) has its own WAN, its own root, and its own WireGuard. The Quickline public /28 lives on...

VLAN plan vlan_plan.json in mikrotik-dashboard is the git-only intent. The dashboard page /vlanplan reads every REST device's bridge / VLAN / port / list membership and judges it against that file. Snapshot below is plan version 2026-09-06, still the live in...

Routing and WAN Two ISPs, OSPF with BFD, a canary route, and a CHR hot standby. The core does not originate default; it installs whichever ISP is cheaper and currently adjacent. Dual ISP Path Box WAN Transit to core OSPF cost BFD Primary CCR2004 Quickline 10....
