This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non-contact switch. This switch can carry up to 1A. This reed switch can be populated easily on a PCB and is encapsulated so it's more durable than glass reed switches. Documents: Datasheet (RS-01C) ...

If you ever find yourself connecting handfuls of resistors to the ground bus of your breadboard, you may consider these SIL-packaged resistors as a time-saving alternative. This Singe In-Line component is actually 5 individual 330 Ohm resistors that share a common terminal on pin 6 (denoted with a black dot). These work great as current limiting resistors for rows of LEDs and two of these can replace 10 individual wire-lead resistors when hooking up our 10 LED bargraph displays. They also work...

4-digit 7-segment displays are really neat little devices, it's a shame that they can be so cumbersome to control. Well we've solved that problem by making them a little bit "smarter." The SparkFun 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines. The Serial 7-Segment Display can be controlled in one of three ways: Serial TTL communication, SPI serial...

Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take up to 6 different kinds of coin! Whether you're building your own arcade cabinet or...

Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take up to 6 different kinds of coin! Whether you're building your own arcade cabinet or just charging admission to your house, this programmable coin acceptor makes it easy to monetize your next project. The sensors in this coin acceptor use the thickness, diameter and fall time of the coins to identify them and it's fully programmable so you're not limited to any particular type of...

Do you fear that your power may not be "far reaching" enough? How would another 3' work for you? Okay, so it doesn't sound very dramatic, but sometimes an extra 3' of power cable is exactly what...

Do you fear that your power may not be "far reaching" enough? How would another 3' work for you? Okay, so it doesn't sound very dramatic, but sometimes an extra 3' of power cable is exactly what your project needs. Don't hack apart a nice clean barrel jack connection just because it won't reach, this male-to-female barrel jack extension cable will make the reach. This cable is terminated with 5.5x2.1mm barrel connectors, one male and one female, and fits most of our products that use a DC...

This 0.005" Muscle Wire® (aka shape memory Nitinol) is a one foot long piece of nickel-titanium alloy that can flex and contract when a specific amount of heat or current is applied to it. If you are asking yourself "What sorcery is this?!" We assure you, this isn't magic, it's just simple science thanks to shape memory and a change between the wires weaker, low temperature form (martensitic) and its stronger, high temperature form (austenite). When the Muscle Wire® is in its martensitic form,...
