@Andrewier....Thanks for that, very well put, I'd forgotten about VGAs. I guess there is some sense to it. Are you sure about DB-31 - I remember seeing a high denisty plug the sdame size as a DB-25 but (like a VGA) with 3 rows of pins, but there would have been a lot more than 31 there....
I am not sure if we are talking about the same (or my bad English is tricking me), but... let it go:
If the matter is DB x DE connector designations, the first letter (D) is for 'D' type (or trapezoidal), second - A,B...E is for shell size and the number, for the number of pins, of course. For example, we can have DB25 and DB31 - same shell size but different number of pins. The same for the - once ubiquitous - DE9 (PC serial port) and DE15 (aka VGA) .
Got them all- I guess I must be an instrument guy. LOL.
I'm not convinced you can't use type B below 0°C but it has a nasty hook around there where it reverses slope, so a given mV can map to more than one temperature, and nobody that I've seen has bothered to measure the mV below 0°C (the only reason to use such a nasty Pt-Rh thermocouple is if you have to go up to very high temperatures (>1500°C)).
I used up my one and only set of questions that were already done. I will tyr to run them one in awhile and perhaps you can help. Please send questions to me at firstname.lastname@example.org. I'll compile them and post.
Thanks as always Martin. Got 3/5 - came short on the language one and no 5. Should have known better on this one as I have come across it before. Silly idea though, if they have a unique letter, what's the point of putting the number?
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.
