wirehead

   [prob.: from SF slang for an electrical-brain-stimulation addict]

   1.   A   hardware   hacker,   especially   one  who  concentrates  on
   communications hardware.

   2.  An  expert  in  local-area  networks. A wirehead can be a network
   software  wizard  too,  but will always have the ability to deal with
   network hardware, down to the smallest component. Wireheads are known
   for  their  ability  to  lash  up  an  Ethernet terminator from spare
   resistors, for example.
