tro3 - not too much. A lot of that falls under the real heavy lifting that senior contributors have brought on. So we have things like NVidia integration (see CUArrays.jl, GPUArrays .jl). I think I read that Julia runs fine on the Jetson Nano SBC :). Then there’s the LibSerialPort.jl which lets you talk over the USB via a wrapper (it works well). There are some efforts for things like, Arduino.jl, but I think that library has become defunct? Either way all you really need is a USB :), but that could be nice to see fleshed out.
Then there’s people working with Andor(.jl) cameras, and camera’s in general(Cameras.jl? and a half dozen other libraries). I saw some stuff about FLIR cameras! Really cool.
I imagine we could see some IoT type efforts. We have people running Julia on raspberry pi’s, tablets, and other ARM devices.
There’s lots of interest in CAD: CAD in Julia? and a OpenSCAD type package in the works (https://github.com/sjkelly/Descartes.jl). People eluding to things like 3D printing, Interest in FEM http://www.juliafem.org/.
Maybe there’s also a SPICE simulator somewhere? I forget.
Lots of things brewing, lots of open areas to explore.
