There are only 3 9V motors in the Lego product line today: - the geared motor as found in the Mindstorms sets. This is the one that has a cube like shape, with lots of irregularities. - the ungeared motor. This is sort of the classic 9V Technic (...) (24 years ago, 11-Apr-01, to lugnet.robotics)

Hi all, Looking through the Pitsco Dacta catalog, I happened to see a 9V Motor with Gear Reductino listed for $16.25. Does anybody have any information about this item? It appears smaller than the standard 9V motor, which makes me think that it (...) (24 years ago, 11-Apr-01, to lugnet.build, lugnet.general, lugnet.technic, lugnet.robotics)

TRU-FLATE tire pressure guages are made by Stant. If you search the Web for "Tru-Flate" you will find several stores that sell them.
