@RichQ....thanks for that. I eventually decided that EET does not like the word "A l e r t" (probably why BeALert spells it with a capital L?) though I'm not 100% sure of that. I did write the comment directly, though I did manage to retrieve it and copy and paste it thru notepad on second and third tries (yeah, I know not to use Word for this).

Now there's a thing! I never even noticed the Edit/Delete link under my posts. Shows how wide awake I am. I'll delete the offending ones forthwith.

That sounds pretty slow. What do you do if you have a bunch of loose resistors in a bag and you're trying to find a particular value... or one near that value?
@antedeluvian - after I posted that I thought I remembered something like that, and eventually decided it must be in your book....I'm gonna look it up at the weekend (I'm flat out like a lizard drinking right now :-)
You're probably one of those guys who can read an E12 resistor almost without thinking. Occasionally you see ones with non-standard values and it's like looking at a word that's spelled wrong (I have some 50Ω ones like that). 1% resistors (5 color bands) are a pain, I don't think I'll ever read them without thinking.
In my book I descirbe an app in Excel where you can select the number of bands and then select the colours from a drop down list to determine the resistor's value. It would then look at the order and pick out a standard resistor value that suited the left to right or right to left order. (I suppose it would have been flummoxed by the non standard values).
I also went a bit further (still in Excel) using voice recognition so that you could call out the colours and Excel would then use the same algorithm to determine the value and then "speak" it out loud.
What went wrong? You probably tried to compose your post with Word or some other such program, and then paste it in. Trouble is, those programs often generate embedded codes that play havoc with our posting system. You need to use the "paste as plain text" feature to strip all that out. Use the folder icon with the "T" on it at the bottom of the edit box.
By the way, after you make a post you can still change or even delete it. Your own posts (and only yours) will have the additional option to edit/delete at the bottom. So if you get a result you don't like, you can readily alter it.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
