##Need
Need = Summed totals minus Have. "Tiny Pcs"/"ATX Pcs" are covered (near-infinite supply on hand), so ThinClients and the LLM-host chassis are NOT listed below — only parts not already owned. Composite items ("Sound System", "Voice Reciever") are broken into their actual sub-components, since "1x Sound System" isn't a single SKU. Amazon links are real listings found via search (mostly amazon.com — search only returned US results; check amazon.de for local pricing/shipping/VAT before buying). No prices are invented below — where docs/project-plan.md already documents one it's reused as-is, otherwise it says "see link."
#GPU (LLM host) — need 1
- Used RTX 3060 12GB (~€200–250, per docs/project-plan.md §1.2) — condition/model don't matter much, 12GB VRAM is the requirement (Q4 Qwen2.5-14B). New alternative: MSI GeForce RTX 3060 Ventus 2X 12G OC
#Beamer (Amirs Room) — need 1
- TMY 1080P Mini Portable Projector, HDMI/USB (see link for price) — budget pick; if the ThinClient output needs to look good on a big wall, a brighter/native-1080p unit is worth paying more for than a mini LED projector like this one
- HDMI cable, length depends on beamer placement vs. ThinClient — not sized yet
- Ceiling/shelf mount — only if not just resting on furniture
#Voice Reciever - round screen thingy (Living Room, Loggia, Linus Room, Kitchen) — need 4
This is firmware/esp32-s3-touch-lcd-1.85c/ from this repo (Phase 14) — each unit
is a kit of:
- Waveshare ESP32-S3-Touch-LCD-1.85C, round touch display dev board
(~€35–45 each per docs/project-plan.md §1.12) — must be the V2 revision, see
firmware/esp32-s3-touch-lcd-1.85c/README.md; the listing needs checking for which hardware revision it actually ships, this repo's firmware assumes V2 (V1 has no AEC circuit and different audio pins) - USB-C power adapter, one per unit — 5V/3A USB-C wall adapter
- USB-C cable, one per unit (often included with the board — check the listing before buying separately)
4x board + 4x power adapter (+ cable if not bundled).
#Sound System (Living Room + Loggia confirmed; Linus Room + Kitchen unconfirmed) — need 1 confirmed, up to 3 total Have 1 already, need 4 total (2 confirmed, 2 pending the "?"/"???" decisions above) → need 1 now, +2 more if Linus Room/Kitchen are confirmed. Each unit is a kit of:
- Fosi Audio V3 stereo amp (300W x2, TPA3255, w/ 48V PSU)
(~€130 per docs/project-plan.md §1.13) — USB DAC/amp for the passive speakers below,
same choice this repo's
hosts/audio-endpoint/andhosts/thin-client/docs already make for amd64 rooms - Micca MB42X G2 passive bookshelf speakers, pair (~€100/pair per docs/project-plan.md §1.13)
- 16-gauge speaker wire, 100ft spool (one spool easily covers multiple rooms — buy once, not once per Sound System)
1x spool of wire total; 1–3x (amp + speaker pair) depending on how many of the "?"/"???" rooms end up wanting one.
#Kitchen — need 1 touchscreen + 1 camera
hosts/kitchen-display/ (Phase 17) — the Tiny PC is covered by "Have", these two
are not:
- 10.3" portable USB-C touchscreen monitor
(see link for price) — needs to expose itself as a native Wayland
wl_touchdevice, not just an emulated-mouse HID surface (unverified either way — seehosts/kitchen-display/README.md) - Logitech HD Pro Webcam C920 (see link for price) — any UVC webcam works; picked for wide availability/driver support, not a specific requirement
#Open items carried over from above
- Whether Linus Room and Kitchen actually get a Sound System (the two "?" marks) decides whether 1 or 3 more amp+speaker kits are needed.
- Linus Room's "???" line is still a completely open slot — nothing to shop for until it's decided what it is.
- Loggia's Lenovo all-in-one is already owned, so nothing to buy.
hosts/touch-panel/now handles either way its touch panel shows up to Linux (nativewl_touch, or an emulated-mouse HID device via thetype:pointerfallback + a udev override to fix it properly — see that host's README "Touch input: two tiers"), so this is no longer a go/no-go check, just worth running once to know which tier it landed in and whether the override needs filling in for full multi-touch.
##Price estimate
Rough figures in EUR, for the #Need list above. Estimates, not live-checked prices — the four docs/project-plan.md-sourced ones (GPU, ESP32 board, amp, speakers) are reused from that doc as-is; everything else is a typical-market-price guess for that exact product category, not pulled from the live Amazon listing (the search used to find these links doesn't return price data — click through and check before budgeting against this). All EUR figures assume roughly 1:1 with the USD prices these products actually list at; check amazon.de directly for real local pricing/VAT/shipping.

Subtotal, confirmed need only (excludes the optional beamer mount): ~€799–1,010 Subtotal, including the optional beamer mount: ~€814–1,035
Not included above — priced separately since they're conditional, not confirmed:

| Fosi Audio V3 amp + Micca MB42X G2 pair (Kitchen Sound System) | 1 kit | €230 | €230 |
If both "?" Sound Systems are confirmed: add ~€460, for a grand total of ~€1,259–1,470. Linus Room's still-blank "???" line isn't priced at all — there's nothing to estimate until it's decided what it is.
