Welcome to our second guest, Kevin Santo Cappuccio, the creator of Jumperless. 6:20 The UNO Plus+ (Kevin #1) The UNO Plus+ from John Loeffler is what the Arduino UNO should’ve been all along. It’s the same shape and hardware as the Arduino UNO, with the added bonus of LEDs on every pin to show you the state. 10:36 Manyfold (Paul #1) Manyfold is a self-hosted solution to organize and share your files for 3D printing. It’s also connected to the Fediverse, allowing you to follow instances (aka server) or creators. You can run it in single-user mode or multi-user. You can also make files public or private, which is great for saving models you might have paid for but don’t or can’t share publicly. Suported file formats include 3MF, Blender, FreeCAD, OpenSCAD, STEP, STL, OBJ, GCode, BMP, GIF, JPG, PNG, SVG, and even video files in MP4 or MPEG. It also support Markdown, PDF, and text files. Demo instance Public instances GitHub repository FLOSS Weekly podcast episode with James Smith 13:52 Quake on a SparkFun Thing Plus Matter board (Tod #1) next-hack.com got Quake running on a Feather-sized board The folks at nexxt-hack.com have Quake running on a SparkFun Thing Plus Matter board. This board is in the Feather format (0.9“ x 2“) and sports a MGM240P wireless module for doing Bluetooth and Matter wireless protocols. This module also sports a EFR32MG24 chip, which is a 32-bit ARM Cortex-M33 processor at 39 MHz, 1.5MB flash and 256 kB of RAM. (This is essentially the same specs as the new RP2350 from RasPi, so maybe we’ll see Quake on an Adafruit Feather soon?) After proving the idea using the SparkFun board, they designed a complete Quake-playing gamepad with built-in screen, joysticks, sound, and battery. This time using the Arduino Nano Matter board (which has a similar MGM240-series module on it) Oh also: you can do BLE-based multiplayer and it runs at 35 fps at 320 x 240.

First - it’s flexible, hence the name and wafer thin. It also includes a few upgrades from the original Raspberry Pi Pico, including using USB-C instead of Micro-USB and a programmable Neopixel built-in. Otherwise, the pinout stays the same as the popular Pico.

The board each student got was custom-designed. It has 8 pots, 12 captouch pads, an OLED display and stereo audio out, all driven with a USB-C 16MB Pico clone. The workshop also talks about how GPIOs work and how capsense works. Looks like it was pretty great!

Paul and Tod welcome their first ever guest, Liz Clark aka BlitzCityDIY. They chat about the itsaSNAP iOS app from Adafruit, the new Raspberry Pi AI camera, maker skill trees, and more. Join our newsletter! Keep up with the show and what Paul and Tod are up to. Visit The Bootloader’s newsletter page to browse the archives or subscribe. Show Notes 00:25 Adafruit itsaSNAP iOS App (Liz #1) I have to say I’m a little biased with this pick because I contract with Adafruit, but I’m mildly obsessed with the new itsaSNAP app. This is the latest iOS app from Adafruit by our iOS developer Trevor. It acts as a bridge between your iOS device and your Adafruit IO feeds. There is support for Apple Shortcuts, which means that you can log health data, home data, any data that’s on your iOS device. You can also read feeds from the device and have Adafruit IO affect tasks on your phone. I’ve worked on two guides with it so far. The first uses a Qualia board with a round display to show photos from my photos app. I’m able to encode the photo in a Shortcut, send it to an IO feed and then decode it with CircuitPython. I’ve also worked with using Matter devices in Apple HomeKit with itsaSNAP to log sensor data and also to control an RGB light strip. I’m really excited about all of the functionality and I’m looking forward to seeing what people do with it. itsaSNAP Intro Learn Guide Qualia S3 Photo Frame Health Status Board 5:09 Raspberry Pi AI Camera Module (Tod #1) There is a new camera module from Raspberry Pi. It’s an “AI” camera. What does that mean? It appears as a regular camera to the Pi, plugs into the CSI camera port. The “AI” part is that it has an RP2040 and 16MB of flash to store a pre-trained AI model you upload to it.

Using a Raspberry Pi Zero 2W, a screen from Ali Express, a Particle IoT board, and his Last.fm account, the screen dsiplays a bumper sticker with what Guy is currently listening to. Guy Dupont on The CircuitPython Show Guy Dupont MakerChat on CircuitPython Day 2024 The Bumpin’ Sticker YouTube video GitHub Repository 13:40 Nothing To See/Hear : Wireless Fuzz Pedal (Liz #2) I follow quite a few guitar pedal folks on instagram and saw the newest post from @different.noises last week. It’s a “wireless fuzz” that completes the circuit by transmitting it via an infrared LED. The circuit converts the signal from the guitar to headphone audio level and then again into light that is sent out the infrared transmitter to an infrared LED. He includes the schematic in the post as well as an explainer and a few demo videos to prove that the signal is in fact transmitting via infrared. Nothing To See/Hear : Wireless Fuzz Pedal Post different.noises on Instagram 16:10 X1Plus alternative open source Bambu X1 firmware (Tod #2) I’ve been thinking of getting a new 3d printer. My Prusa mk2.5s has seen better days. And I’m wowed at the literal 2x speed improvement I could get out of a Prusa mk4s or a Bambulab X1. So when I discovered this X1Plus alternative firmware for the X1, I was intrigued. The X1Plus firmware runs on the “application processor” (AP) board of the X1, (sort of like what Octoprint does for me currently). It doesn’t touch the motion control system. And seems like all does to the the AP firmware is patch the bootloader to also look for a firmware file on the SD card, and use that if present. So you can always go back to stock firmware quickly. And the team behind it have started a CrowdSupply campaign for an expansion board X1Plus can use for extra features light lights and cameras. I don’t think I’d want this, but I’m glad they’re finding a funding path for the keep them going. X1Plus X1Plus expansion board crowdfunding Hackster article 22:31 Maker (and more) Skill Trees (Paul #2) Steph Piper aka Maker Queen has created Maker Skill Trees as a way to track your progress across a range of skills. These include things like PCB Design, 3D Printing and Modeling, and Dev Boards to crafting skills like Crochet, Knitting and more. There are almost sixty different skill treens to pick from. Each skill tree has 73 skills or experience hexagon tiles, with basic skills at the bottom to more advanced skills at the top. There’s a web app to create your own skill tree apps designed by Shane Gadsby. There’s also a book in development with an even more expansive range of skill trees, tools to track your progress and calculate your life score across all areas. Enjoying the show?
