James Housley On the Way!

TAPT-ers,

Sorry, I neglected to send this over the weekend, I temporarily lost it in my mountains of email.

From Jim:
Here is a list of items that I have in some degree of surplus, and available to bring

Float and chain engineering problem solving set:  ability to make one each of a thermometer, a hydrometer, a barometer, and a milligram balance, and to modify them to vary their sensitivity and/or range.  This was discontinued from PASCO's catalog a few years ago in a housekeeping purge, but perhaps someone has an old pasco catalog and could see details.  This was my response to need for STEM before STEM became a thing.

Mirrors 150 mm sq, with a base that holds them normal to a table top. Lots of uses besides the obvious.

Density sets of 12 pieces of aluminum, all different sizes.  Graphing mass vs volume gives a straight line graph, whose slope is the density of aluminum.

UV color shifting beads, white but become colored under uv, including the uv in sunlight. Then return to white after a delay. also transparent disks that appear identical, but some block uv, while some transmit it.  results can be seen using the beads.

thick plastic material that has amazing thermal expansion in hot or cold tap water.  disks, and pieces that have holes that are a near fit for the disks.  like the classic brass ball and ring apparatus, but no bunsen burner is needed.

Small vacuum pump and bell jar, a few sets.

Singing rods, that can can be stroked to make a longitudinal oscillation with loud sound.

A small number (3?) to donate of the dial indicatiors that I showed once before that Karie mentioned in her e-mail.  They show how it is that a seemingly immovable floor or wall can exert a force.  I will try to bring some ancillary parts to make all this ready to do this demo.

No guarantees as to quantities I can bring, but I will bring the largest item of luggage allowable on the plane, and will try to respond to requests.  NOTE NOTE NOTE I will seal up the box or large suitcase Tuesday night (1/23) so any requests after will likely have to wait an extra year.
