cipher - Resistance is futile


On the sunny morning of April 5th, 2063, an alien spaceship started orbiting the Earth. Among the cries of "It's an alien spaceship!" and "Ohm my god!" from the people, governments noticed that they were beaming down a colorful message:



V over I equals?


Unfortunately, because of interference from the atmosphere, they were only left with this small fragment.


Can you decode the fragment, and hence guess the entire transmission?



Answer



The date given, April 5 2063, is the launch date of the Phoenix spaceship from Star Trek.


The title "Resistance is futile" also alludes to another famous Star Trek phrase. Therefore, the answer is likely to be related to the Star Trek franchise in one way or another.


Translating the code using this table


results in the text:



760 101+050 101+180



101+010 320 101+080


101+110 111 101+030


320 970 111 012 320 (interpreting the 9 as a blank breaks the message)



Interpreting the bars similar to the 3-bar resistor code (with the least significant digit encoding the exponent of 10 when 3 bars exist) results in:



76 100+5 100+18


100+1 32 100+8


100+11 110 100+3


32 97 110 100 32




which decodes to ASCII



Live long and (?)



Assuming the context of Star Trek, the answer is probably



Live long and prosper
