The US1881 is an integrated Hall-Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage,...

We love heat shrink! We use it for all sorts of handy projects. Use it to reinforce connections, protect devices, and electrically isolate exposed solder joints. We worked with a manufacturer to create a kit that we would use: lots of colors, lots of sizes, nothing too long. We specially requested some of the sizes with heat sensitive glue which significantly increases stress relief and water proofing. This kit includes 95 pieces of heat shrink, all of varying colors and sizes, and comes in a...

These DC powered heating pads are perfect for near-body heating applications. They get warm to the touch but not too hot as long as you provide the appropriate voltage. Simply apply 5VDC to the wire leads and within minutes, the pad will begin to warm up. These heating pads are constructed using a mesh of Polyester filament and Micro Metal Conductive Fiber folded into a protective Polyimide Film. The fact that these are low power, flexible and draw little power makes them ideal for things like...
