What do you get when you combine the BBC’s Doctor Who with an open-source hand-shaped mini-computer? The HiFive Inventor Coding Kit: A Wi-Fi-and-Bluetooth-enabled Internet of Things learning platform for young engineers!
The HiFive Inventor is a visually stunning IoT-enabled hand-shaped mini-computer designed to teach young engineers how to control robots, interface with IoT systems, or build their own sonic screwdriver to investigate the world around them. With built-in Wi-Fi and Bluetooth technologies, this strengthens the wireless data handoff between devices (or “HiFive”) that will power 21st-century technology applications of computing for smart cities, intelligent factories, and enhanced wearable technology.
The HiFive mini-computer has several onboard sensors, along with a front panel LED matrix and two buttons. On the bottom is the familiar micro:bit-like edge connector for attaching additional peripherals, including a speaker. A battery pack, alligator clips, and a light-up LED USB cable are also included.
Change your face with this unique LED mask, like it’s the return of the classic Nicholas Cage/John Travolta action classic, Face/Off!
Be whomever you want. This Face Changing mask uses the same LED panels from Lumen Couture’s matrix line of dresses and hoodies, allowing you to fully transform your face. Comfy eye sockets and ergonomic design allow for long term wear.
This innovative mask is controlled via Bluetooth app and includes presets, text, equalizer effects, and the ability to upload your own images. A variety of equalizer effects respond to sound and music. The mask has a sensor to support hand gesture movements to change your presets. The mask contains over 2,000 individual LEDs with fast response rate supporting realistic effects.
DT71 Mini Digital Tweezers are among the nicest, most handsome digital test equipment we’ve come across. The DT71 is compact and pocket-sized for easy portable use. They’re a perfect assistant for folks who have assorted SMT components that need verification – either because they aren’t marked or because the text is so tiny. Great for checking passives, we like them for QA procedure and also to make sure our 0402 RF components are the right values before soldering them in. You can also use it on live circuitry to verify voltage
DT71 Mini Digital Tweezers feature a pair of thickened gold-plated interchangeable tweezer tips. The tips can automatically measure SMDs including resistor, capacitor, inductance, voltage, frequency, and diode. Meanwhile, a built-in miniature waveform signal generator can output a variety of waveform signals. The DT71 Mini Digital Tweezers are a chic, well-designed addition to your toolkit for testing and debugging.
The Raspberry Pi Compute Module 4 is based on the Raspberry Pi 4 Model B, but in a smaller form factor – perfect for embedding into products or projects without the bulk of a classic Raspberry pi. You get all the computational power of Raspberry Pi 4 in a compact form factor for deeply embedded applications. The CM4 incorporates the same quad-core ARM Cortex-A72 processor, dual video output, gigabit Ethernet, UART, I2C, SPI, I2S and a few PWM for good measure.
Cooling fans…They’re everywhere, and they serve the important purpose of keeping things cool, generally electronics. One might rightfully think: “these fans are pretty good at moving air to keep things cool; maybe I can use one of these neat computer fans to keep my widget frosty” followed closely by throwing up one’s hands in confusion at the sight of a 3 or even 4-pin connector. OK, power takes two pins but what are these other pins for and how do I use them to convince this fan to keep my things chilly?
Add lots of touch sensors to your next microcontroller project with this easy-to-use 12-channel capacitive touch sensor breakout board, starring the MPR121. This chip can handle up to 12 individual touchpads with plug-and-play STEMMA QT connector and large alligator/croc-clip friendly pads, its a no-solder solution to capacitive touch sensing.
The MPR121 has support for reading data over I2C, which can be implemented with nearly any microcontroller. You can select one of 2 addresses with the ADDR pin (solder it close for the alternative address), for a total of 24 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity.
