Old Engine Analyzers

Here are some very bulky antiques from the Deer Park Auto Museum.


These are old engine analyzers.  Today, our cars can give digital dumps of all their internal sensor data.  But back in the day, technicians would have to learn how to apply these beasts.  I had a few electronic projects back in the 80s and 90s where I got to play with oscilloscopes.  It's all fascinating to me, so lost to the world. 

There is so much information here, so many gauges, actual cords to plug in.  So much knowledge needed to get results and do the analysis.  Signs, meters, technical speak, it was another time.

Yield Signs: Flow Chart Style?

Image
  There are some yield signs around town whose appear to targeted at a very small audience: people who like to read flowcharts.  Sure, you can stand there and work out what they're trying to say, but I'm sure 99% of people who walk by just shrug and think "whatever". I don't know if they bug me because they're trying to be too clever, or too dense.  Maybe they just remind me of work.

Need More Nines

I know that retailers love to use prices just below the dollar marks to try and fool us into thinking tge price is lower than it is.  So $2.95 instead of $3.  Sadly, it works.  Almost everyone who sees $2.99 has some chunk of their brain thinking it's only "two something", not properly rounding up to three. But what's the deal with this?? $2.99.99 is not a real use of numbers. May 15 update: we saw a short documentary on the 99-cent stores going out of business, and I think it said that company invented the extra .99 bit during a few years of trying not to raise their prices to $1.

Lost Remote?

Image
  Here's a fun sign.  Someone lost their remote control for some kind of "machine".  The sign was there for about 3 weeks before some major construction began, so I walked back over and got a picture of the sign surrounded by machinery.  I doubt that any of those trucks are remotely controlled, so the sign and the machines are probably unrelated.  There's just a lot happening on this corner. Yesterday, the sign was gone but judging from this new sign, the construction is going to continue for another month.  Note that June 31 is not a real date, so does that mean they don't have an actual completion date in mind?
