 This week on Maker Update, a shouting pumpkin, build your own feather module, be goose due crimes, boiling cauldrons, dripping skulls, and open-source e-readers. Hello and welcome to another Adafruit edition of Maker Update. I'm Tyler Weingarner, and I know what you're thinking. Halloween's done, you've set your clocks back, it's time to rake some leaves, count down the days until next Halloween, and think of all the projects you'd like to do for next year. Well, we've got you covered, so let's get started with the project of the month. The Ruiz brothers combined the circuit playground blue fruit and the SEMA speaker module to make this talking glowing jack-o'-lantern. There's only a tiny amount of 3D printing in this project. Instead, they hacked an existing toy pumpkin by gutting all of its existing electronics and replacing it with their own. There's two parts that provide mounting points for the circuit playground and the speaker module with a small LiPo battery tucked in between them. The project is controlled using the Adafruit Bluefruit LE Connect app. The app presents a handful of different modules to create a number of different hardware interactions, but here they're using the controller. Pressing each of the soft keys displays a different color and plays back a different sound file. The code is written entirely in circuit Python, which makes sound playback and neopixel control a breeze. They've also added a toggle switch to the circuit to turn the pumpkin on and off. I love this project, not just because it's the perfect thing to greet trigger treaters as they come to your house, but it's a great jumping off point for hacking lots of other Halloween decorations. You're bound to find glowing skulls and dancing skeletons sold cheap at your local craft store or home center now that the holiday has passed, and the circuit playground blue fruit is the perfect board to start turning them into your own spoopy interactive decorations. Now for the news. Beginning November 1st through to the end of this year, Adafruit is hosting their take flight with Feather Contest, which challenges anyone to design their own board for the Feather ecosystem. There's separate categories for ridiculousness, cutting edge, assistive technology, and more, but every single entry will be judged for its manufacturability. If your entry is picked, a run of a hundred boards will be manufactured and stocked at Digikey. Super cool. Last weekend, O'Reilly held their TensorFlow World Conference, where ARM and Google distributed the official conference badge, an Adafruit Pi badge with TensorFlow Lite Micro pre-installed. With an onboard microphone and pre-loaded with the voice recognition demo, it's a great place to get started with machine learning. Finally, Adafruit hosted a buy one give one donation campaign for Black Girls Code, a non-profit that creates learning opportunities for young women of color in various tech disciplines. Within a few hours, Adafruit maxed out their donations of Circuit Playground Expresses. Digikey offered up another round of hardware, and they ran out again a short time later. Hopefully there will be a third round if you want to contribute to the generosity. Back to more projects, last month the Adafruit featured hardware was the Monster Mask, and everyone went nuts adding this to their costumes and projects for Halloween. Erin St. Blaine used it to create the eyes and control the barking mouth of this furry fizzgig from the Dark Crystal, while John Park made animated eyes for this weird meat-head charcuterie centerpiece. Phil Burgess refreshed this old costume mask with new eyes and a microphone to change his voice to something a little more menacing. Deep kiddos and the all-size snickers, yeah. Those are the best. Speaking of menace, John Park also used the Monster Mask and a microphone as a controller for untitled Goose Game, triggering the in-game honk by using his own voice. And finally, Timothy Weber paired the Monster Mask with an IR grid sensor to create a pair of eyes that would follow you as you move around the room. Phil Burgess created this weird creepy drippy glowing dragon skull with an Adafruit M0 Basic Proto Feather, several strands of the skinny 4mm Neopixel strips, and some individual Neopixel dots, and a whole lot of patience. The Neopixel strands were attached to the outside of the skull to create paths for the drips, and then painted over with white paint to hide them. Then the individual Neopixels made splats for each strip with land. It's a great example of using Neopixels to create animation, and a cool effect if you have the patience to deal with the wiring nightmare. The Ruiz brothers used the Circuit Playground Bluefruit to create this tiny glowing frothing cauldron. The printing design for this one is super clever. The board sits at the bottom of the cauldron beneath a thin translucent shield. The inside and the brim of the cauldron is lined with a phosphorescent putty called Glow Flow, and the fog is made by dry ice melting away in some hot water. The Neopixels shine through the shield, lighting the fog, and changing colors. It's a cute project, and a ton of fun. From the Adafruit community we get the easy make oven from Dan Cogliano. Toaster ovens have long been the darling appliance of DIY reflow setups, but this project turns it into a much more refined tool with the addition of a pie portal for monitoring temperatures and creating heating profiles. You won't even need to hack your toaster. The temperature is monitored through this Adafruit thermal couple and regulated through this power outlet relay module. Perfect if you're squeamish about working with high voltage devices. The pie portal lets you define your own temperature curves and then see how close the actual temperature matches. It's a great build for anyone looking to move beyond through whole soldering. Time for some tips and tools. Last month was Open Hardware Month, and Adafruit made a post every single day about open hardware projects, communities, and other related topics. If you missed it, now you can find the links to all of these posts on a single page. Head on over and dive right in. Speaking of Open Hardware, the Open Book project from Oddly Specific Objects is an open source e-ink e-reader based on the SAMD51 ship and a feather form factor. Heavily inspired by the Pi badge, one of the coolest things about this project is the silk screen on the custom PCB. There's tons of documentation about the project on here. From pinouts with their functions clearly labeled, tons of info about the components on the board and more. It's a great use of the real estate offered by a large board and ensures you'll have something to read even before you load it up with books. There's a few new boards that you'll be able to use with Circuit Python. One of them is the SparkFun Quick Micro. Quick is a relatively new board ecosystem allowing you to chain numerous components together over I2C. The Quick Micro itself is a tiny board like its name suggests, a little larger than a quarter. With several GBI Opins, it might be what you need for your next project. You can also start writing Circuit Python code on the Sony Expressense and the Arduino Nano BLE Edition. For this month's Adafruit product spotlight, we're checking out the Stemma non-latching relay. This is a tiny versatile relay module that you can use in just about any project. The relay can be triggered by either three or five volt logic and the relay itself can carry current loads of up to 60 watts. Not something you want to use to turn your oven on and off, but can certainly be used to trigger a lamp and plenty more. You can easily experiment with higher voltage projects from any development board and there's space to attach an additional three pin terminal to control more circuits. And that is going to do it for this week's show. I hope your post Halloween is giving you plenty of time to think of new projects or start working on them.

We'll see you soon.
