We just added links to the video launching this morning at 8AM. It includes the FreeCAD Automation Claude Skill, an MCP the skill uses to communicate with FreeCAD. And the torsion box that is in the video itself. Hopefully others find this useful too.

AI and CNC goes beyond just the pendant we previously built. New video coming tomorrow morning demonstrating using agents to build for the physical world. Plus the update on the #lowridercnc I've been working on. It is absolutely amazing what is possible, but it wasn't without its challenges, so be sure to check it out when it goes live 8AM CT

I finished cutting ribs for the new torsion table on the Low Rider V4 from V1Engineering. A new product arrived and a review is coming shortly on that. Claude Code is up an running on the PocketTerm35 a video will be coming for that one too. Spars are next for the CNC. Exciting new Linux desktop underway for Raspberry Pi optimized for the touch screen and qwerty keyboard of the Waveshare device. Be sure to stay tuned.

The new hardware I hinted at in the last video arrived. I am in the process of building something I hope everyone will find interesting with it right now. Video coming soon. Anyone want to guess what it is?

After our first EEZ Studio overview video, we heard from you that a more detailed walk-through of the AI generated UI's was desired. We're putting that video together now. We also have some new hardware on its way that is a touchscreen with a keyboard. We have specific plans for that one, can't wait to share it with everyone. Additionally the Low Rider V4 CNC build is still happening, so if others are interested in that project, please let me know. I can plan an update video for that one too if there is enough interest.

We have another ESP32-P4 video coming tomorrow morning CST. This one is for all of those frustrated with high prices. It's a full review and demo of the features of an ESP32P4 that costs less than an Arduino Nano ESP32. Be sure to watch it when it goes live. I think you'll be amazed by the cost and what it can do. I was.

When we first received the Waveshare ESP32 P4 the mic and speakers were key features. The primary use case for these was to allow the HMI used to control lights, view device data, could also communicate with Peregrine our AI voice assistant running on the Dragon Q6A. We got it working, and this video walks through how it works, the code, and the case design that allows the mics to reach the back side of the display.

We just finished our case design for Fireside our 7 inch HMI that you can take with you. The concept is simple use the Wavesahre ESP32P4 with a similar interface to Milepost, but use WiFi + MQTT. Then add a battery so that it can be taken off the wall and go Fire Side with you. Allowing you to control and monitor what's happening inside your rig, while you are outside. Now as it gets dark you can remotely turn on the outside lights, keep an eye on the temperature inside as it drops, see how your battery is doing without the sun providing power. Then we added to it a push to talk functionality that interacts with Peregrine our AI Assistant. Video walk through dropping today at 9AM CT. We walk through the functionality, the code, and the case design. Hope others enjoy and find it helpful for a project they have.

For anyone who was interested in the ESP32P4 that we featured a review of and you use Arduino. Good news it appears the board support packages are available now. github.com/espressif/arduino-esp32 We haven't had a chance to build an Arduino sketch with it yet, if we get time we'll do this and put the example code on our GitHub

We purchased the Arduino Uno Q to create a lite version of our edge computer in the TrailCurrent platform. Some interesting findings after exploring the board fully. If you're considering Raspberry Pi for your next project, this might be worth knowing about. So check out the video, and let us know whether this seems like a good fit for your project or not. Also let us know the details about the project so others can see which ones it might make the most sense for.
