These red plastic wheels press-fit onto the 3mm D shafts on many of Pololu's motors, including Pololu's micro metal gearmotors and Pololu's plastic gearmotors with 3mm D-shafts, to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36″) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with several of Pololu's universal mounting hubs. The wheels are sold in pairs.

This single disc load cell (sometimes called a strain gauge) can translate up to 50kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the disc. With this gauge you will be able to tell just how heavy an object is, if an object’s weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.
This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal.

These beefy, bright red plastic enclosures will give your widget the protection (and attention) it deserves. You’ve probably seen these used to enclose radio equipment or antenna baluns as they can be secured to a pole using U-bolts (not included). At about 3mm thick, this 74x158x90mm enclosure has plenty of space for gizmos, gadgets, widgets and doohickeys. The mounting flanges extend 19mm from either edge with two 50mm-spaced 7mm diameter holes.
This is a basic, 4-digit 7-segment display - red in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points.
No really - it’s 6 inches (153mm) tall! This very large 7-segment display can be seen from a hundred feet away. So many projects to try, so little time…
For a long time we’ve had small 7-segment displays and huge 7-segment displays, but now we finally have something in between. These 20mm 4-digit 7-segment displays are big enough to see from a distance but not so big that you’d have trouble finding an enclosure for them.
