These are small rare earth magnets - 3/16" rings. Composed of Neodymium/Iron/Boron (NdFeB), these magnets are curiously strong and make for a great way to attach tools to a metal workbench, hold small children to a fridge, and as a trigger for reed switches. This one small ring can easily hold a piece of paper to your fridge. We found these small rings to be very useful for connecting PCBs together. These rings are conductive and can act as a magnetic connector between widgets. You need a way...

This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits. The unit outputs gray code so that you can tell how much and in which direction the encoder has been turned. This unit does not come with a knob, but a working knob is related below.

This is a heavy-duty joystick very similar to the ones in claw arcade games. Directional movements are momentary limit switches - one for each direction. This joystick also has a select button that is actuated when the red button is pressed down. This joystick is pretty beefy and very tall because of it. We built up an enclosure just to see what it would look like. Ideally, this joystick would be panel mounted, but actually reading the movement of the joystick is as simple as setting up the...

It's not what project you have in mind that may use a rocket launch switch... The question is what project will you come up with once you have one in hand? Everyone has a proverbial missile to launch. The hot red safety cover protects a toggle switch from accidentally being turned on. When flipped up, the user has full access to a switch underneath. Upon closing the cover, the cover will force the switch arm back into the lower position - a safety mechanism so you can quickly hit the cover...

An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user! This is a center-tap linear type potentiometer. The outer two pins will always show 10K resistance, the center pin resistance to one of the...

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,...

The QRE1113 is a small IR reflectance sensor. This sensor is often used in line following robots because, if it can sense if a surface is white or black. There are four pins on the QRE1113 - two control the IR emitting LED while the other two are the collector and emitter of a phototransistor. The IR diode has a max forward current of 50mA and operates at 940nm. Breakout boards with analog and digital outputs are also available.

This is a simple SPDT slide switch - great for use as an ON/OFF button, or just as a general control switch. The pins are spaced by 0.1", however they are incredibly thin making breadboard use not recommended. The switch is rated for 0.3A at 50VDC. This switch is just a bit smaller than our popular SPDT Mini Power Switch, but uses the same pin spacing. Being smaller takes up less PCB space (good!), but it does make it a bit harder to hit and flip easily. Documents: Dimensional Drawing ...

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC, up to 5A. Fuses are pretty simple, if more than 5A pass through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully your circuit is saved from molten destruction. For smaller loads, you may want to checkout a PTC (aka resettable fuse) listed below. These handle less current (500mA) but can be set and reset...

The seven band graphic equalizer IC is a CMOS chip that divides the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. The seven frequencies are peak detected and...
The seven band graphic equalizer IC is a CMOS chip that divides the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. The seven frequencies are peak detected and multiplexed to the output to provide a DC representation of the amplitude of each band. No external components are needed to select the filter responses. Only an off chip resistor and capacitor are needed to select the on chip clock oscillator frequency. The filter center frequencies track this...

Rubber feet raise your PCB or project up off your desk. This helps prevent short circuiting from bits of scrap wire floating about or setting a project down on a conductive surface. They also prevent your enclosure or PCB from sliding around. They can also be used as feet for enclosures. These are self-adhesive and 16.5mm in diameter and about 10mm tall. They taper to roughly 12mm at the top. They come in a set of 4.
