I2C stands for Inter-Integrated-Circuit communications, it's meant for short distances on a PCB or subassembly. But, hey, we're engineers, and we like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer? Well, if you try to do that you'll quickly find that the length of the cable adds capacitance and resistance that slows down the open-drain pullups used in I2C, making it...

The LPC1347 LPCXpresso board is part of NXP's LPCXpresso eco-system of low cost development boards based around the free (GCC and Eclipse-based) LPCXpresso IDE. All LPCXpresso boards include an on-board hardware SWD/JTAG debugger, so you don't need any additional hardware (other than a USB mini-B cable) to start some serious debugging (including setting and stepping through breakpoints, etc.). The LPCXpresso boards are actually two separate...

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. We do have some other handy level shifters in the shop, from the DIP 74LVC245 to the fancy bi-directional TXB0108. However, neither of these are happy to work with I2C, which uses a funky pull-up system to transfer...

With this  Tri-Color USB Controlled Hemisphere Alarm Light with Buzzer,  you can easily monitor and alert humanoids as to the status of a project, machine, or even if the bathroom is occupied! Unlike our "12V" style tower lights, no wiring or microcontroller programming is required. It's completely plug-and-play for use with any computer that has a USB port, even a Raspberry Pi SBC - so we recommend it when you just want...

With this Sealed Tri-Color USB Controlled Hemisphere Alarm Light,  you can easily monitor and alert humanoids as to the status of a project, machine, or even if the bathroom is occupied! It's a lot like our other alarm light but this one doesn't come with a buzzer and in 'exchange' it has a sealed body which means it can be used in places with more dust and moisture. It doesn't have an official IP rating, but we think...

A large-sized rechargeable battery pack for your Raspberry Pi (or Arduino, or Propeller, or anything else that uses 5V!). This pack is intended for providing a lot of power to an GPS, cell phone, tablet, etc but we found it does a really good job of powering other miniature computers and micro-controllers. If you want something a little smaller, we have a 5000mAh power pack with one USB port that can provide up to 2.1A We tested it with an iPad...

We decided to stock this food-safe heat shrink specifically for people who were building beer-brewing or sous-vide projects using our waterproof DS18B20+ digital temperature sensors. This heat shrink is FDA Compliant for contact with food. The end of the sensor is stainless steel, but the jacketing is PVC, not good for dunking into your food or drink! But this heat shrink makes it easy - simply slip it on, allowing about 1 cm of the stainless...

Build an "Internet of Things" connected mini printer that will do your bidding! This is a fun weekend project that comes with a beautiful laser cut case. Once assembled, the little printer connects wirelessly to get Internet data for printing onto 2 1/4" wide receipt paper. Based on a Raspberry Pi computer, this is a powerful mini Linux machine. We have example python code for a few different printouts including a daily weather...

The Pololu Zumo robot is an Arduino-controllable tracked robot platform that is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. It includes two micro metal gearmotors coupled to a pair of silicone tracks, a stainless steel bulldozer-style blade, an array of six infrared reflectance sensors for line following or edge detection, a 3-axis accelerometer / 3-axis magnetometer / 3-axis gyroscope, and a buzzer for simple...

Try the JavaScript of things with the Espruino - the world's first open-source JavaScript microcontroller! This little board has an STM32 microcontroller pre-programmed with Espruino all ready to go so you can start playing with Javascript-microcontrollers. Warning: if you only use Assembly and think that even embedded C/C++ is for wimps, this device might explody your head. The Espruino is a tiny computer with a JavaScript interpreter,...

These LED strips are fun and glowy. There are 32 RGB LEDs per meter, and you can control each LED individually! Yes, that's right, this is the digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component with 7-bit PWM precision (so 21-bit color per pixel). The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. Only 2 digital...

As electronics get smaller and smaller, you'll need a hand examining PCBs and this little USB microscope is the perfect tool. Its smaller and lighter than a large optical microscope but packs quite a bit of power in its little body. There's a 2 megapixel sensor inside and an optical magnifier that can adjust from 20x (for basic PCB inspection) to 220x (for detailed inspection). Eight white LEDs are angled right onto whatever you're...

This cute little dongle is perfect for making your Raspberry Pi cable-free by adding WiFi. Take advantage of the Raspberry Pi's USB port to add a low cost, but high-reliability wireless link.  You'll have wireless Internet in 10 minutes! Works great with 802.11b/g/n networks. This is the official Raspberry Pi foundation version , for use with the most recent Raspberry Pi operating systems.  This module is also supported by Windows...

This graphical display looks great, costs less! The dark gray pixels are visible in daylight, and there's also a full RGB LED backlight, which you can control with PWM to make any color you can imagine. Four mounting holes and a blank 11 pin 2mm-pitch labeled breakout on the side - we just soldered some wire to each hole as shown in the photos, its very easy. (The LCDs have no wires soldered in when we ship them) Bonus! We're including a...

Deprecation Warning: The Trinket bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Trinket so that people can maintain some older projects, we no longer recommend it. Please check out the Trinket M0. It has built-in USB, more capabilities, and is comparable in price! Trinket may be small, but do not be fooled by its size! It's a tiny...
