Ask HN: Most interesting tech you built for just yourself?

Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

The G-Seat as part of my sim-rig. 9 AC Servos, borderline dangerous, beast of a simulator. The G-Seat I decided to do better than commercial offerings (had tried "the best" and it was pretty average). CNC brake folded aluminium seat with moveable flaps controlled by AC Servos - had to 'de tune' as they were literally at rib-breaking speed initially. About a year worth of development designed and prototype in Fusion 360, through to this :

And another vid at max rpm on the servos...

That is the coolest thing I've seen in a long time!

This is awesome. I've wanted to go down this route for a while. Every time, I basically give up at the point where I decide I want to check out https://opensfx.com and then realize I don't have an easy way to get a referral.

I'm currently using a NLR Wheel Stand, and probably don't have time to build right now, but if you'd consider shooting me an email at chris at cjkinni.com I'd love a chance at actually going down the route of building one of these. No worries if you'd prefer not to.

Great work on the whole thing!

The only simulator I’ve ever been able to drive in was one with air bladders in the harness that applied pressure backwards. I would love to get one, but it was quite pricey.

If you build the hardware and start working on the software, publicly, a sponsor would probably hear about it and sponsor you.

Ive had an idea for a flight sim station for a while, but its no where near diy'able am afraid - to be able to 'mimic' different g forces, im thinking a big 'arm' rotating (like the one soviet cosmonauts and i think fighter pilots were trained on), with a capsule in the end of the arm containing a cage with a chair, rotatable 360 deg, with a screen - so if you need sode Gs, youd just rotate the cage so that your side is facing outwards...dunno about the doability at all :D
