 T4D #156 - DriveMo Fail, DeWalt Winner..and News

In this video:
I had a failure while using the DriveMo tire inflator that I wanted to share as I had just reviewed it.
I went out and purchased a DeWalt tire inflator as a comparison / alternative as I need something reliable to use on my truck tires (tyres)

General Discussion / Very odd lamp I just saw
« Last post by SeanB on October 02, 2022, 03:13:51 PM »
Just pulled an odd lamp out. Still working, just been getting a little wet. Still was lighting up in the fixture, yet the lamp tubes themselves were full of water. Very odd to have a CFL lamp where the actual glass tube itself was full of water, but this lamp was still attempting to operate and emit light.

T4D #155 High Accuracy Clock...and Rabbit Holes!

In this video:
* A look at how my high accuracy clock is doing after another year of testing.
I set it up for another year and show how the Keysight 53220A frequency counter / timer has been very useful to collect data.
* Chit chat about my interest in water purification measurement and the rabbit holes it's led me down.

Older Technology / An odd item for sure

Decided to see what is inside this bit of arcane test equipment. Test gear, but while it is electronic, the use is definitely biological, and it has only one use.

Hennesey meat grader, what is used to set the quality of the meat you buy. Push the probe into the meat, and this machine does some arcane work with sensing in the probe, probably involving detecting fat content and water, then makes a decision as to what grade will be applied to the meat. Thus there is a need to attach a printer, probably a serial one via the power cord, and print out the grade, A, B, C and the class 1, 2, 3 of the meat, that is then used to run a coloured ink roller down the side in a line, to show, even after it has been sliced up into smaller parts, the grade of the original.

Has a case you can remove for cleaning, and then an inner housing on the electronics, with the 68705 CPU, with 16k of memory, and the external program EPROMs as well, plus the interface to the rest of the unit. Bottom board with the analogue stuff, and probably using some form of ADC to communicate with the CPU, and the isolated serial interface to the printer. 555 timer there as well, probably doing reset.

Definitely something is wrong, either there is another board hidden in the front, which does power conditioning, as 3A is a little high for power draw, though it does have sensing, so it knows when the probe is pushed into the device under test, and the speed of this, so it likely does evaluations on all aspects, rating according to depth as it goes in.

Power up and it does sort of work, but without the other half, which I do not have it remains a curiosity, made likely 1999 from the date codes, and never being repaired in this time, though there are a few minor revisions on the board, where there are extra components added probably due to earlier ones having common failures.

Your display or theme is probably different from mine... on the white / light gray of mine the red shows up prettily but I have difficulty reading T PrimeŽs yellow posts. Alright, IŽll stick to black.

I played champ 9394 english for 26 seasons on the Amiga and right at the end a message box came up with "congratulations" partially crashed out though, the game then crashed. Did the game on the Amiga have a maximum lifespan??

I tried installing the four files in the elogind directory, which were "elogind", "libelogind0", "libelogind-compat", and "libpam-elogind", but it tells me that purging consolekit is still going to remove like 200 things.

32 Bit Float Audio - Real World Advantage With Zoom F3

In this video:
I demonstrate how 32 bit audio works and how it saved my bacon doing a binaural recording of the Bryson City Great Smoky Mountains Railroad train.
I show my workflow in Vegas Pro and Audacity.
