If you have a modern smart phone you may have noticed that it comes with built in wireless charging capability called 'Qi charging.' Qi is a trademark name for a thin and smart inductive charging system. Many large gadget companies have...

Ever since the Kindle eReader came out, we've been wanting a nice small graphical eInk display that is easy to use with a microcontroller. And finally our desires have been fulfilled with the rePaper 2.7" development board from Pervasive...

That new Raspberry Pi® Model A or B computer you just got has a row of 2x13 pin headers soldered on - those are the GPIO (general purpose input/output) pins and for those of us who like to hack electronics they are where the real fun is....

This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or 'USB wall adapter'. Charging is performed in three stages: first a preconditioning charge, then a...

This is for people who just want to get cold fast. The 12V Peltier module is mounted onto a 12V heatsink and fan assembly with thermal paste and an aluminum clamp. Simply connect to 12V 5A+ power supply and you will see frost appear on...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This...

The cute PiTFT got even more adorable with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT uses the high speed SPI interface on the Pi and can use the mini...

Pogo pins are little spring-loaded contacts, very handy for making jigs, or making momentary (but electrically solid) contacts. We use them by the dozen for making programming and testing jigs but they're handy also if say you want to...

The classic 'third hand tool,' as seen on every desk! Adafruit have one next to their Panavise jr, they complement each other well. This tool is good for holding small PCBs and wires for tinning or soldering to parts. Every part can...

Get glowing in seconds with our Electroluminescent (EL) Panel Starter Pack! This pack contains everything you need for your first EL panel project, even the batteries! Includes: 10cm x 10cm (approx 4"x4") square panel in White Portable...

The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. The eTape sensor's...

This tiny little camera module can be a pretty neat project addition, it is just like our other JPEG cameras (same chipset/software), but much smaller and slimmer. It was designed to be used in security systems and does two main things -...
