Quick post, a couple of drawings.

October 1st, 2009 | Categories: Electronics, Personal Projects, Work | Tags: , , ,

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.

    Hi Steve,

    I am wondering if you have the data sheet on this LCD. I have several that I picked up somewhere a few years ago, but have no info as to how to get data to lines 3 and 4. Lines 1 and 2 work OK.

    I’ve never been able to find a specific datasheet for the QY-2004A but it is hd44780 compatible and works just like any other.
