A web console to control nanosatellites Nahuel Garbezza
context Satellogic builds nanosatellites using open hardware and software technologies
@CubeBug1 launched, @CubeBug2 to be launched soon they needed a visual console for improving the interaction with the satellites
context Console Radio Satellite sockets
let’s see some of the key aspects of the project
#1: discover the domain we did test-driven development from the
beginning a lot of concepts & patterns emerged
let’s browse some classes :-) #1: discover the domain
#2: visual sending & reception of packages web interface using
Seaside components a lot of JQuery / Ajax integration with DataTables JQuery plugin
#2: visual sending & reception of packages demo: let’s see
the console running!
#3: display charts timeline charts using Highstock JS library (bindings
with Smalltalk)
#3: display charts
#4: parse command definitions code that runs in the satellite
is written in C we used PetitParser to extract the command definitions
#4: parse command definitions demo: browse some PetitParser rules configuration
from the web interface
#5: let the users write custom scripts built-in commands are
‘primitives’ console users know Smalltalk so… we let them write Smalltalk code scripting support using metaprogramming
#5: let the users write custom scripts demo: creating and
sending scripts from the console some technical details
conclusions great opportunity to work on a real project using
Smalltalk personally, to gain experience on TDD, OO design and Web development
thanks to Hernán Wilkinson Gera Richarte
end questions/comments are for sure welcome :-)
