IMO the fuel used to go to radioshack and the time and effort expended to make all of the connections and the guess work put forth for the hook up totally exceed the $17.00 you would spend on the invisicord and the 2 minutes it takes to connect it... JMO.
im usually for that, but it was fun to learn something at the same time save money (radioshack - 2 miles away, motorcycle 40 mpg, premium gas 3.00 = $.30) AND i get it NOW!
PLUS i know how to do it so i can sell it to friends for cheaper than invisicord, and i can do whatever length i want. Time to build, maybe 5 minutes at most, hardest part getting it plugged in.
ME
Gas/Time = .50
Phone cord = free
Connectors = 2.00 (pack of 10)
Total = $2.50
Supplies left over = do same for another car OR sell for $10 to a friend
Total 1 = $2.50 for two cars
Total 2 = $7.50 in my pocket
You
out $20
I just like to see the entrepreneurial side of things, not that it would lead to anything with this, but just fun. Like i said on some things i agree Time and travel are better saved for an easy click of the button, but this time was a learning experience.
