Was in the area of electronic equipment from the midst 60s until today, it has been to some awe struck amazement to watch technology move from the reduced tubing of yesterday to today’s modern wonders in electronics. It seems to the particular engineer, but that there’s a passion in making what we use digital, which much of the simplicity and ease of this analog has been lost and in many cases that the Rube Goldberg doctrine of engineering has been adopted: Why do something simple when it is possible to make it complex?
Case in point: Did you know that there is a cable that expands and contracts depending on the temperature? We used it at thermostats. Why then do you need a processor controlled, cushioned, high tech control that carries a 15 page illustrated book of guidelines to turn on the heat into a chicken coop, garage, or a greenhouse?
If you keep in touch with some of the younger engineers now and cite Conventional current or perhaps a Logarithmic nomograph, they will start looking at you like you are speaking in tongues. For people that have no idea very well what a nomograph isalso, it’s a set of parallel perpendicular graphs that will show you that 20 volts across 5 ohms dissipates 80 watts. That is carried out by simply drawing a direct line through the charts.
Now they solve the problems by copying a group of numbers to a screen and also an algorithm concealed in a type of code somewhere in a program spits out an answer. If asked how the answer was arrived in the they answer”it’s there on the screen”.
People are able to learn previously. For a time NASA couldn’t hit their butt with a plank, not to mention successfully land on Mars. My creation managed to property on the outside with out too much trouble. You’d think that following the first two or three failures somebody would go back in the archives and then determine how it was done.
Do not get me wrong. I do not desire to return to the time of this PDP-8 computer that was a row of octal programmable switches, fed by paper tape, and had 4K of memory. But it would be fine once in awhile to really have something come on without getting the command”Please wait until the device boots.” Just because technology is old does not mean it isn’t relevant. I would like to get a piece of equipment that includes a switch that actually turns something and off without even talking to a chip.
