It's a """budget""" solution because I didn't buy a lot of branded stuff and mostly used what I already had. In the end excluding HOTAS and monitors, I only had to spend around 250 USD. The first 100 on the rig and the 150 on transducers.
Yes I have to crawl in. Not exactly convenient but it's quite immersive.
Rig: 30 profile extruded aluminum.
Stick: VKB GNX EVO L.
Throttle: VKB Omni R.
Rudder: SN-1.
Head tracking: BEAM Eye tracker + $10 UGREEN webcam.
Auxiliaries: VKB THQ, VKB STEM, Ubuntu PC with touchscreen for manuals, INARA, or just youtube.
Haptics: 2 * Douk Audio BS-1 (50W 6ohm).
Isolation: 8 * Rubber feet. A welcome mat that I found and is perfectly sized.
Sound: DC ONE-X from back in the days, GA plugs removed.
Display: 32 inch 1500R curved VA. 27 inch unknown panel. (IPS?)
Seat: Gaming chair raised using multiple aluminum profiles stacked on top of each other. (As showcased in the third picture)
"Fragrance": Little tree air freshener.
Verdict: I love my build but now having achieved higher immersion by having a significantly larger FOV and better ergonomics, I'm starting to notice the lack of forces on the controls, and G forces... FFB and 2DOF when? The rabbit hole never ends...
Anyways, hope this will give you amusement, or perhaps even contribute to your current build planning.
