I had a random thought that I would love to have a super tiny full acrobatic fixed wing airplane to fly in very tiny outdoor spaces like a small backyard, or maybe even inside. I was actually quite surprised to come up empty handed. Almost every other area of the RC hobby has gone micro, except this area. Even just acrobatic foamies seem to mostly be quite large.

We have full fpv quadcopters weighing in at around 20 grams.

We have full 3d collective pitch helis that fit in the palm of your hand.

We have tiny little 1:43 drift cars with gyros and all wheel drive.

I did see some pretty small palm sized homemade airplanes, though they weren't acro.

I realize this could be challenging, and probably extremely wind sensitive, but it seems like it would be possible to make, considering how tiny and light as motors and servos have become. I'm thinking something small made of perhaps 2mm foam with maybe some 1.5mm carbon fiber bits where needed, and a tiny little motor with a 2-3 inch prop. Something that weighs like 15-30 grams.

Think we will ever see something like that? Or does something actually exist that I missed?

I have a 1U server that has dual AMD Epyc CPUs (64 cores, 128 threads each), plus 128GB ram.
However it is so slim that I think GPU options are quite limited to only very slim server GPUs

My max budget I'd want to consider spending for a GPU would probably be about $1500. I found limited options in that range. There is a 16GB vram T4 that I can find used for about $500 but when looking at performance, it seems to be absolutely stomped by almost any 16GB consumer GPUs like a 5080, so I don't know how much value it would have. And those consumer GPUs are way too large to put in this slim host that only has room for a very slim card.

So with a GPU likely out of the picture, is there any good local LLM use that could actually make good use of all these CPU threads and ram? Or is this just not going to be a good LLM rig?

I tried doing research before asking this, on a few occasions, but just found too much mixed or outdated information to know what is accurate.

I've never had any interest in a smart watch before. IMO they seem like a pointless gimmick, running tiny limited versions of apps that you can do better on the bigger screen of your phone. I also assume (though I could be wrong), that they lower security posture, by allowing a certain level of access to your typically locked phone via a typically unlocked watch. Not to mention I assume there is an risk of accidental input on them. They just seem stupid to me.

However I started having an interest purely for use with Onewheel / VESC . The idea of being able to see your speed and battery, and hopefully duty cycle (I think I heard this can only be done on a VESC board but not a onewheel, but I'm not sure), has me quite interested.

I considered just getting a "renewed" Galaxy watch 6 for about $100.

However I'm having a tough time even finding a good set of pictures or video of what the app even looks like, particularly for VESC. Apparently the floaty app supports a watch, but after a lot of googling I couldn't really find any good pics/vids what it is even like. So I couldn't really even tell if I might like it.

Also I really worry if accidental input will be a concern. I don't want to be able to accidentally brush it and it changes my ride profile or something.

Also I'm pretty sure I'd have to modify the band to fit around wrist guards.

So that seems like a lot of potential negatives.

I'm curious for input from you guys what you think about these topics and whether you use a watch and think it is worth it or not?
