Learn the basics of designing and making things with Inventables' software (Easel) and 3D carving machines (X-Carve and Carvey)
This book was written for people who have never carved before. It teaches the basics of designing and making things with Inventables' software (Easel) and 3D carving machines (X-Carve and Carvey). It showcases five step-by-step projects you can build yourself as a beginner, including an inspiration tile, kitchen cutting board, custom block stamp, fidget spinner, and balsa wood glider. The book also features a gallery of aspirational projects, like an electric guitar and a box joint toolbox, to show what else is possible through 3D carving. The design files and instructions for these more complex projects can be found on the Inventables website.
Projects Included
Participate in the world's largest mosaic tile wall
Build a glider to your own specifications
Create your own inlay cutting boards
Carve a fidget spinner toy
Craft wooden 3D stamps you can use to create your own greeting cards

This 900 MHz radio version can be used for either 868 MHz or 915 MHz transmission/reception – the exact radio frequency is determined when you load the software since it can be tuned around dynamically.
At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3 V logic. This chip has 32 K of flash and 2 K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.
To make it easy to use for portable projects, we added a connector for any 3.7 V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
Features

The Feather 32u4 Radio uses the extra space left over to add an RFM69HCW 868/915 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you ned more range than 2.4 GHz (BT, BLE, WiFi, ZigBee)
SX1231 based module with SPI interface
Packet radio with ready-to-go Arduino libraries
Uses the license-free ISM band ('European ISM' @ 868 MHz or 'American ISM' @ 915 MHz)
+13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)

Create multipoint networks with individual node addresses
Encrypted packet engine with AES-128
Simple wire antenna or spot for uFL connector
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. Headrs are also included so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna.

A low-power, open source, 2.7-inch IoT display powered by an ESP32-S2 module and featuring SHARP's Memory-in-Pixel (MiP) screen technology
The Newt is a battery-powered, always-on, wall-mountable display that can go online to retrieve weather, calendars, sports scores, to-do lists, quotes…really anything on the Internet! It is powered by an ESP32-S2 microcontroller that you can program with Arduino, CircuitPython, MicroPython, or ESP-IDF. It's perfect for makers:
Sharp’s Memory-in-Pixel (MiP) technology avoids the slow refresh times associated with E-Ink displays
A real-time clock (RTC) was added to support timers and alarms
The Newt was designed with battery operation in mind; every component on the board was chosen for its ability to operate at low power.
Newt was designed to operate 'untethered,' which means it can be mounted in places where a power cord would be inconvenient, for example a wall, refrigerator, mirror, or dry-erase board. With the optional stand, desks, shelves, and nightstands are also good options.
Newt is open source, and all design files and libraries are available for review, use, and modification. However, doing that is not required. Each Newt is delivered with working code with the following features:
Current weather details
Hourly and daily weather forecast
Alarm
Timer
Inspirational quotes
Air-quality forecast
Habit calendar
Pomodoro timer
Oblique Strategy cards
Only following the Wi-Fi provisioning instructions is needed to get started. No app downloads are required.

Newt is designed to operate for one to two months between charges using a 500 mAH LiPo battery. The exact run time varies. (Heavy Wi-Fi use, in particular, will reduce battery charge more quickly.)
USB Type-C connector for programming, power, and charging
Low-quiescence voltage regulator (TOREX XC6220) that can output 1 A of current and operate as low as 8 μA.
JST connector for a Lithium-Ion battery
Battery-charging circuity (MCP73831)
Low-battery indicator (1 μA quiescence current)
Software
Newt hardware is compatible with open-source Arduino libraries for ESP32-S2, Adafruit GFX (fonts), Adafruit Sharp Memory Display (display writing), and RTC RV-3028-C7 (RTC)
Arduino libraries and sample programs are under development and will be available in our GitHub repository before launch
CircuitPython libraries and registration are on the roadmap, with the development of a CircuitPython library for the RV-3028 real-time clock as a key dependency

The Unicorn Pack fits nicely on the back of your Pico - with a tidy 7x16 matrix (that's 112 RGB LEDs!) it's surely the fanciest backpack going. The four tactile buttons can be used to switch between modes, as controls for simple games, or adjusting brightness. It's possible to control the colour and brightness of each LED individually so you can use it to display animations, text, simple images, and more. Make a mini photo FX lamp, a smart status light for Zoom, use it to display colourful scrolling messages on your fridge, or just enjoy some pretty animations. Features 16x7 matrix of RGB LEDs (112 total) Individual colour/brightness control of each LED 4 x tactile buttons Pre-soldered female headers for attaching to Pico Compatible with Raspberry Pi Pico.
