Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Evening Gents..

Just doin some playing around with a new Thermo (or any type of sensor) Measurement System IC called the LTC2983... SPI based and easy to use and get going... Has 20 channels input... Since CHT probes are hard grounded on the "hot" end, you can use the IC in differential mode, feeding both sides into a different channels to get the temp result... Single ended also works well if you are using isolated type thermos... The video shows the "raw" data samples being displayed, not averaged, so the system appears to be very stable during testing so far... I am throwing away quite a few bits of data as I am only interested in whole degrees...

I put the Demo Video on DropBox...

Hope it works..

Impressive display unit.
Yet another demonstration of practical uses for the 'mites.

Sophisticated and impressive. The bar graphs look especially cool.

Great set-up there Zonker, and fantastic screen layout

Please can you post details about the BT module (Is it a low-power BT 4 module by any chance?)

Nice work Zonker. Since I came in to the display thing kind of late, could you tell me which display you are using in that project and how you made the 2 color buttons across the top, also how you implemented that cool 7 segment number font? Sorry for all the questions.

I'm sorry gent's.. I didn't mean to deceive anyone... The display i am using is from 4D systems and I have been working with it since even before there was such a thing as graphic LCD's and the mites, I was using it for the EIS project as one of several possible choices a pilot could use inside there cockpit setup...

The main thing about the demo was the new thermocouple IC I am trying to get settled in.. The main thing about the display is the cost... At $200, the unit does produce awesome looking UI objects and can work with the Micro Mites... (sweet) BUT, because of the awesome work being done by Geoff and several other "C" coding guys here at the shed doing the same thing (or close to it) it will soon be possible to get the same things done at $50..! THIS is the reason I am SO interested in the many new things being done by Matherp and many other fine folks on TBS..! I know all of this is going to take some time, so I just need to "cool my jets" and let things settle in... The future for the the "Mites" project is very bright indeed..!

I am kind of "dumb ass" when it comes to coding work as I am more of a "hardware" guy... Without the Micromite and writing in basic, I would never have attempted such a project as the EIS system... That is also why i LOVE the TBS..! We, functioning as a group of people who have talents in several areas can share the work load to come up with amazing stuff..!!

I am starting to see that more people are getting evolved in the fine work going on here at TBS..! Example.. This morning I will be going over to Barry Carter's house to get him pop started on the Max Mite box that Matherp sold to me a few months back... Also, a new guy, John Williams just bought one of my DIP-600-28 boards and will be starting up soon... SWEET... Bring it on..

Yikes...
You mean the telephone..? If, so, yep, my wife got that from her mother and just likes the "old school" types of phones.. I must admit the receiver part does seem the fit, feel and function better and longer to your ear that the new stuff.. Also, feels better in the hand, so you can put up with it for those lonnng conversations...

Are you saying that it is in two pieces???? The controller base station and then the handheld wired apparatus that you talk and listen with???

Just kidding of course as I was raised with these also, however, my young son can't get enough of comparing his iphone to what we had back in the day. Amazing how now the young ones want to convert the old phones using cellular modules and make "old school" new again... I've actually seen one used in a car.

HERE is an idea for the uMite and GSM module just for fun. At least yours has a keypad...

OLD SCHOOL??? At least you have the `modern' push buttons.. My first phone had a dial like this one..



I am sure Don's first phone was more like this one.

PS> Great work on the project.. I love it (I dont mean the video quality)

All those diallers look strange.

I'm from the voice recognition era.
Provided the operator hadn't gone to bed, you just had to pick up the handset and ask for the number.

That's rural Queensland in the 1970's

Yes. It was a great 50th birthday present for him at the time. Newfangled.

Those were the days. They ran the phone service along the fencing wire. It was probably more reliable.

Funny you say that, Until a year or so ago all of our `country' race meetings in Victoria were on dial-up modems (9600 baud). At one track, I think Dunkeld or may have been Hanging rock.. Hmmm memory is fading.. They had many issues of the modem dropping out and needing to be redialed, especially in wet weather, this went on for many years until some `young phone tech' discovered that someone had decided, when installing the line into the `shed', (Yes literally a shed) where the control room was, that they would, instead of digging a trench, they would run the phone along about 200m of fence wire..

Regards,

Mick

That was the PMG (Post Master General) special.



It was better looking than the old one.

You had to watch out for the electric fences when you ran the phone along them. It gave new meaning to the shocking phone call. Edited by BobD 2015-06-08

So the meaning of CHT in the post title: does that stand for 'Calling Home Technology'?

The first phone I worked on was more like this:



Basically week 1, year 1 of my Technician In Training (PMG-1959), we had to wire up the loom for this phone from a schematic. :-)

Cheers Don...
