NEW PRODUCT – Thermocouple Type-K Glass Braid Insulated – 5m


Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare-wire bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200°C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. There’s a small piece of heat shrink on the end to keep the fiberglass from fraying. If you’re using at >250°C temperatures, simply remove it with a small blade.

  • K type thermocouple with glass over-braiding
  • Good up to 500°C (900 °F)!
  • Color-coded wires
  • 5 meters long 
  • Best used with a thermocouple amplifier such as the MAX31855AD8495 or MAX31856

We have a handy tutorial which covers thermocouple use including both CircuitPython and Arduino libraries, and example code!

NEW PRODUCT – Color Coded Header for Raspberry Pi


Here’s a snazzy accessory for your Raspberry Pi Zero or Zero W, a color-coded 2×20 header! This Color Coded Header takes the mystery out of your Raspberry Pi’s 2×20 pinout. No longer will you stare in confusion at all 40 pins, trying to count out which one you want to plug your wires into.

3907 top demo ORIG 2018 08

Peep this handy color coding:

  • Red = 5V
  • Yellow = 3V
  • Black = GND
  • Blue = Do Not Connect
  • Green = GPIO

Connecting to your Pi Zero requires a bit of soldering, but if you’re looking for an alternative, try the solderless GPIO Hammer Headers!

Please note: only the Pi Zero and Zero W come without a header pre-soldered. You won’t be able to use this with the Pi 2, 3 or Zero WH as those Pi’s have pre-attached header pins.

Bluefruit LE Sniffer – Bluetooth Low Energy (BLE 4.0) – nRF51822 – Firmware Version 2: Interested in learning how Bluetooth Low Energy works down to the packet level? Debugging your own BLE hardware, and trying to spot where something is going wrong? Or maybe you’re writing a custom application for your phone or tablet that needs to talk to existing BLE hardware, but you don’t know how it works beneath the surface? We have the perfect tool for you!

This Bluefruit LE Friend is programmed with a special firmware image that turns it into an easy to use Bluetooth Low Energy sniffer. You can passively capture data exchanges between two BLE devices, pushing the data into Wireshark, the open source network analysis tool, where you can visualize things on a packet level, with useful descriptors to help you make sense of the values without having to crack open the 2000 page Bluetooth 4.0 Core Specification every time. See more!

Black and White Eye Stickers: Looking for something extra to jazz up your papercraft, cardboard or robotics project? We spy with our little eyes these Black and White Eye Stickers – they’ll will make an excellent addition to your craft supplies! Eye caramba, are we making a spectacle of ourselves? These puns are getting cornea and cornea.

These quirky eye stickers come in six styles, so you can mix and match all sorts of googly looks, endowing your robotics or trashbot with some seriously expressive eyes. Each sticker measures roughly between 1.5 and 2cm. See more!


3846 02
High Temp Waterproof DS18B20 Digital Temperature Sensor – 3m long: This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C – the limit of the sensor itself. That said, it’s still not recommended for salt-water or corrosive environments since the stainless steel will eventually rust! See more!

Mini On/Off Push-Button Switch: Push once to turn on, push again to turn off, push again to turn the other side on, one last push and it’s off again! It’s basically a push-button toggle switch that connects and disconnects.

This clicky Mini On/Off Button switch makes a great power switch or mode toggler. They’re often referred to as ‘flashlight’ switches because you see them used in small flashlights. Can reliably handle up to 500mA and up to 12VDC. See more!

CD DVD Spindle Motor: What’s this? A record player for ants?? Not at all! This is a DVD/CD Spindle Motor, that thing that’s inside a CD or DVD player, that turns the disc around really fast. These motors have some great benefits that make them easier to use than ‘130’ style DC hobby motors See more!

Convex Glass Lens with Edge – 40mm Diameter: The eyes have it! Add this little lens to make a big expression with our Spooky Eyes demo for microcontrollers or Raspberry Pi. These are gorgeous glass (not plastic/acrylic!) lenses, with brilliant clarity and a nice convexity (is that a word?) They’ve even got a lip-edge so you can mount them easily with a 38mm cutout.

Adafruit HalloWing M0 Express: This is Hallowing..this is Hallowing… Hallowing! Hallowing!

Are you the kind of person who doesn’t like taking down the skeletons and spiders until after January? Well, we’ve got the development board for you. This is electronics at its most spooky! The Adafruit HalloWing is a skull-shaped ATSAMD21 board with a ton of extras built in to make for an adorable wearable, badge, development kit, or the engine for your next cosplay or prop.

On the front is a cute 1.44″ sized 128×128 full color TFT. Our default example code has our spooky eye demo running but you can use it for anything you like to display in glorious color.See more!

  • For one, they’re mostly flat on the end, so you can tape or glue it to a flat surface easily.
  • They are well balanced, don’t vibrate a lot which makes them nice and quiet compared to most other motors (they’re not totally silent)
  • They spin fast, about 3500 RPM at full power – can PWM the motor driver to reduce speed
  • 20 mA free running current, 400mA stalled.
  • The motor is rated at 5.9V max. You can use 3V to 6V DC, the speed and torque may vary
  • They’ve already got a plastic hub on em, so it’s super easy to attach whatever you like

It is a motor, so you’ll need a motor driver to control it. We recommend CRICKIT for easy motor control, but you can also use an Adafruit Motor Shield for ArduinoMotor HAT for PiMotor FeatherWingL293DTB6612 or DRV8833.

Because the sensor signal is digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

3846 detail 02 ORIG 2018 08

The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. If you want something really simple, and you have an analog input pin, the TMP36 is trivial to get going.

You’ll need a 4.7k resistor which is required as a pullup from the DATA to VCC line when using the sensor. Here’s a CircuitPython/Python guide for these sensors. We don’t have a detailed Arduino tutorial, but you can get started by using the Dallas Temperature Control Arduino library which requires also the OneWire Library.
