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.

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.

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.

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.
