@suetanvil mostly I'm just excited about the fact that there are companies sharing this sort of information.

It's not FOSS or anything, but it's better than nothing :)

@thurloat yeah, it's got various sensors and such to avoid collisions, etc. and seems to lean toward "fail-safe" behavior.

That said it is a toy, so I'm sure it's far from perfect. But it's also small an un-armed, so the fallout from a crash is probably minimal :)

@thurloat seems to work OK. Relies heavily on the on-board flight control and feedback loops.

Attempting to align my head with facing another day in the hell that is aws <-> oauth <-> Keycloak

@KitRedgrave this reminds me of “Bahamas-driven development”.

@h there are churches in Silicon Valley?

@vertigo good point, I'm sure there's many ARM flavors that can't handle even rudimentary Linux.

@vertigo Basically I want to design an board with an FPGA on it that's pin-compatible with this:

https://www.pine64.org/?page_id=1486

So maybe I can find an FPGA with an embedded ARM core that I can map-out to these pins (with the necessary glue logic, etc.) and then run a tiny Linux kernel on it so I can upload bitstreams, move data in and out, etc.?

I'm sure I'm over-simplifying but this is the gist, to have an "application-specific" logic module compatible with the Clusterboard :)

@vertigo Yeah I guess I've seen it before but I wasn't aware that it was becoming common.

It's convenient for me because I'll need some way to glue my FPGA fabric to the Ethernet interconnect 😁

I'm learning a lot of interesting shit about FPGA from this book (besides what I expected to get out of it).

For example, I didn't know that it was common to have one (or more) "hard" ARM cores embedded in the FPGA chip. Even though I'm moving #rainpsc away from ARM, something like this could simplify the "application-specific logic" SODIMM modules I want experiment with.

I really need to get "in the world but not of the world'" tattooed somewhere that I'm constantly reminded of it.

(I'm not religious, but I love the sentiment of the phrase)

@msh

I really like MQTT for this sort of thing.

@cypnk @kelbot

@kelbot

Yeah as cheap as they are, it doesn't take too much "fiddling time" to eat-up their value compared to devices that are more cooperative.

But that said they are a lot cheaper if you need more than one or two.

@cypnk

@cypnk

Yeah I might have to dig it out and play with it sometime. I knew a lot less about embedded the last time I took a swing at it.

@kelbot

@cypnk

nice!

I bought this one to use as a Piratebox but for some reason it was super slow. Never got a chance to debug it.

@kelbot

@cypnk

totes.

I have some cheap little router that even has built-in lipo & charging, would probably be a slick little off-grid thing if I put something linuxy on it.

@kelbot

@cypnk

Yeah, sorry for dive-bombing the conversation, I just saw "ESP*" and "overkill" in the same sentence and couldn't help myself :)

Recycling those cheap routers is a clever hack.

@kelbot

@cypnk

ESP8266 has 8 pins, costs less than a dollar in quantity and has no operating system (in the usual sense).

If that's overkill, what's underkill? 😂
