So I’ve been working from home for a while and now I’ve moved all of my equipment to my place of work. I’ve been given a new office to work from and it seems promising so far. I’m also going to revamp my site a bit. I’m not certain as to wether or not I want to keep the gallery intact or use it as a backup server for my images. At this point, I’m not entirely sure.
So, hopefully I can get some stuff done this winter and continue riding well into december. Let’s hope so I guess…
After a couple of weeks of solid work, the laboratory viscometer is almost ready for extensive testing. Since this is a redesign and simplification of the older design, it has a few more features and a couple of drawbacks in relation to a brand name Stormer Viscometer. I’ll detail some of the features and drawbacks.
Viscometer can produce results in both KU and MPa*s.
Viscometer can be used as a gel timer.
Viscometer can derive a trend plot of viscosity over time.
Current design is highly simplified, requiring only a 2.25″x1.875″ circuit board and an appropriate power supply, this allows it to fit in smaller, potentially hand-held units.
Has an easy to use menu system to allow lab techs to calibrate the unit themselves and operate it easily.
Has a keypad for data entry, used for time lapses and calibration (Oil values)
Relatively cheap to produce.
No spring to break, unlike the Stormer viscometer.
Unit does not do live sampling, thus, any kind of watch-and-wait testing has to be done by the computer. This is due to the fact that the motor has inherent changes along the time line and therefore a fix sample time is necessary.
Unit is a single CPU unit, unlike the larger in-process version, thus requiring a great deal more finesse in programming.
May still be difficult to detect low-viscosity fluids like water and alcohol. Different motor may make the difference.
Things to do so far:
Finish motor mount – almost done anyways, need encoder though, hence why I’m using the in-process viscometer device for now.
Test and program – of course, who know how long this will take, though, the majority of the difficult work is already done.
