Working on new viscometer head

  Well, I’ve been designing some new stuff since having a little wind of inspiration. This head weighs in at about 700g and provisions have been made to allow an attachment to a handle and therefore a hand-held version could be made. Here are some images.

  I’m going to use these design concepts on the next in-process version. I’m going to design the external case for the electrical portion and for possible battery storage. Since the motor only draws 100ma at 24v or 200ma with a 12v motor, a hand held version is definitely possible. This version will use a PIC16F767 for control and using a smaller LCD display to display info.
  Now, on to developing some other devices. I’ve wasted far too much time in the last many months, time to get busy.

Quick post, a couple of drawings.

The chill is in the air, October is here. I’ve been pretty busy with the viscometer and some other things, however I drew a couple of objects just for future reference. I figured somebody might need the dimensions of either a stormer viscometer paddle (as measured from a real one) or a QY-2004A white LCD display (blue backlit)

Anyways, here are the links to the drawings in PDF format.

I’m going to draw up some of the rarer parts I have, I may need them later and somebody else might be able to make use of them. Keep in mind, these are rough drawings taken from measured features. Don’t assume that the measurements are the same for all units except perhaps the stormer paddle.
