I am still playing with my data acquisition board from Digikey.

It works, but I cannot get it to work reliably so far. It locks up at
times during the boot sequence and I then need to disconnect it for a
few minutes to get it to respond again.  I suspect that the problem lies
within my code that configures the USB port ... time will tell.

Every few days I get an email from an online seller called Meritline.
The stuff they sell is almost always super-cheap imported stuff. And I
have purchased quite a number of items from them.

This morning´s online ad has digital thermometers  on sale.  I purchased
one of these a month or so ago for the kitchen; I think I paid $2.79
total - including shipping.  It works fine on pot-roast and has a
temperature range of 50°C to 300°C (- 58F to 572F)  ±1°; , which would
make it suitable for measuring most engine parameters.  I am curious as
to what sensor they use so I ordered another one that I can examine more
closely.  I wonder if the lenght of the temperature probe can be
increase to 2 meters or so.??? When I´ve played with the one I already
have, it appears that the sensor is located in the very tip of the
probe.
