<Ellied>
there's this lab at my uni where admin basically threw an absurd amount of funding at it without consulting hardly anyone and it's kind of horrifying
<Ellied>
it's a robotics lab, up in the farthest-flung corner of the top floor of the computer science building, and they have all this absurdly expensive hardware (high-power solenoids and pneumatics and stuff, 3D mice, overpowered PC rigs, etc) and about half an idea of what to do with it
<Ellied>
last I saw they had a raspberry pi 3 in the middle of a giant tangle of breadboards with a USB wifi adapter plugged into it with '802.11ac' written on it in huge letters, which I think sums up the whole show pretty well
<Ellied>
7-gigabit wireless standard packaged with a 5-gigabit interface, plugged into a 480-megabit bus

So, I've got big plans for my next project (the RPi shutdown one is still in progress, @Ellied), but I think I am kind of stuck with one thing. I will need remote one-way communication with an RPi on a mass, volume and weight budget, in a range of at least 20 m, preferably up to 50 m. Radio control seems to be the only appropriate thing?
<APlayer>
(It should be a quadrocopter)
<APlayer>
Anyway, given I am likely looking for radio control, anyone got experience with specific circuits for that? I was looking at "ARM MCU WL TE122", on some forum mentioned as the most widely used one, but I found rather limited documentation and would like to know if there are alternatives
<APlayer>
Also, having no experience with RC things whatsoever, I have not found power requirements for the receiver module. Are those passive?
<APlayer>
(Or however you call things that don't need extra power)
<egg|zzz|egg>
so I guess when you extend them they become long boys

.tell APlayer if you're looking for a relatively simple radio transceiver system, you might try nRF24L01+ modules. They have libraries written for them for Arduino and Python that shouldn't take an unreasonable amount of work to understand how to use.

!wpn whitequark

<Ellied>
!tell APlayer nRF24L01+ modules can be found with integrated amplifiers and high-gain antennas that will reach a pretty respectable distance, very likely more than your given 50 meters (ostensibly up to a kilometer, but I don't know how much to believe that).
<Qboid>
Ellied: I'll redirect this as soon as they are around.
<egg|zzz|egg>
... why did that ping me
<egg|zzz|egg>
oh, integrated
<Ellied>
lol
<Ellied>
!tell APlayer if you're looking for something easier to program, though, you might consider high-power WLAN adapters and ad-hoc networking. You can find plenty of information about how to set that up online, and use a simple socket interface in your programming language of choice to communicate over the connection.

Ellied: I'll redirect this as soon as they are around.
