Here is a real time clock based on the DS3234 Real Time Clock IC. The DS3234 is a low-cost, extremely accurate SPI bus real-time clock with an integrated temperature-compensated crystal oscillator and crystal. The RTC maintains seconds,...

These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern. When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as...

This is a board designed for opto-isolation . This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by...

These are original Sharp color TFT-LCDs designed to be used in the PlayStation Portable. 4.3" of beautiful 24-bit color with powerful LED backlight. 480x272 pixels - each pixel has RGB control. Data interface is 24-bit so start looking...

This is a simple 2-terminal microswitch, with a 36mm actuator. This switch has a great 'clicky' sound to it, and a nice tactile feel. We used these while lighting up a cupboard at home using led lighting. It can handle anything between...

Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they’re usually unreliable or difficult to implement. Well not anymore! We’ve found this great fingerprint module from...

Even though the Tron movies have been out for a while, electroluminescence is still the coolest thing since sliced bread. The only downer is carrying around a battery pack and bulky external inverter. Good news, we've found a slim...

This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR from Interlink Electronics will vary its resistance depending on how much pressure is being applied to the sensing area. The harder...

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...

Put the pedal to the metal with this metal foot switch. This is the same kind of foot pedal you might find switching the power supply for a tattoo machine or as a sustain pedal on an electric piano. The non-slip pad on top and rubber...

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). This sensor can measure up...

EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. They come in many bright colors (check below for other colors) and...
