My free, open source head unit now records your GPX tracks and gets you to the trailhead fully offline, and one cheap RTL-SDR dongle turns it into an aircraft and ship tracker, weather and FM with station names.

Say "Hey Peregrine" and this free, open source head unit gets directions, places calls, sends texts and changes the radio. All of it runs on the device, and nothing gets sent anywhere.

Episode 2 is up, with the code and a browser demo

Everyone turns the ZimaBoard 2 into a NAS. I made it talk back instead.

Peregrine, our 100% offline voice assistant, running Llama 3.2 3B on an Intel N150 — no GPU, no cloud, powered by a 12 V solar battery.

This is by far the most exciting part of the #trailcurrent build. Bringing together the chassis and the home of an RV. Thanks to @Elecrow1 for providing the first rotary encoder. It features a #raspberrypi #radxa and #esp32 youtu.be/pNoItkKmAoQ

The ESP32 dual MCU rotary encoder from @waveshare00 is such a great device. Not only does it feel premium, you can use this tiny device to interact with AI models via voice. #esp32 #espidf #trailcurrent youtu.be/Mb--lo8JHgw

A quick preview of the upcoming infotainment system I'm building. youtube.com/shorts/cAcR58P…

Finally the day has come to move from the living side of #rv #campervan #vanbuild #cargotrailerconversions into the vehicle side. With @autogradelinux powering it, this is our biggest undertaking yet. So excited to share all the details soon. Video soon

Most people think a DIY CNC is wood-only. My LowRider V4 pocketed solid aluminum, isolated traces on a PCB, and cuts full 4x8 sheets.

Who should build one, who shouldn't, and what it really cost me.

Thanks to Ryan @V1Engineering

I usually find R&D fun but this latest device from @waveshare00 turned my R&D into a 100% game. It's addictive so you've been warned. youtu.be/0esTvmPxCdk

TrailCurrent started with a phone full of apps that never talked to each other. The goal was always one rig.

Now it's real. Walk through a travel trailer in your browser where the wall screen, dial, phone, TV and voice assistant

I've spent a lot of time recently putting together embedded controllers and human machine interfaces. I thought it would be helpful to others to compare them all. So pro's and con's find the one that works for your project youtu.be/kf5-_xXYL1A?si…

More #esp32s3 rotary encoder touchscreens, this time from @Elecrow1 and featuring a ring of addressable RGB LEDs. These make for a super engaging tactile HMI. Check out the full video youtu.be/YeALDDWP1Us

A dial that operates your computer is such a fun way to interact with your desktop. Thanks to #makerfabs for sending the 2.1" #esp32s3 rotary encoder with touch screen. I love this device. youtube.com/shorts/XwPXe5p…

Rotary encoders provide a tactile way to integrate #hmi or #humanmachineinterfaces thanks to #makerfabs for sending us the screen. Full video here youtu.be/3zQSPBUo-Ls This is a great #esp32 #esp32s3 device

It's been a while since I've been able to add a new #trailcurrent module excited to announce #trailcurrentcapstan a truly tactile experience. trailcurrent.com/blog/meet-caps…

I'm a little late discovering this, but #eezstudio released a new version with a simulator. Then #lvgl released new widgets in version 9. The combination is amazing. Then throw an AI agent at it. youtu.be/TTyShNJZgZ4?si…

I tested using AI to build a #torsiontable for my CNC. The results were impressive. Video launching at 8AM CT. You won't want to miss it. Links to the torsion box, skill, and mcp all in description. youtu.be/10SrEGDkLX0

I recently finished the core build of my #v1engineering #lowridercnc V4. Store bought lumber is NEVER straight though, so first job on it. A torsion box to improve flatness. Can't wait to get to surfacing on it.

Sometimes when you build an advanced system, you also need to build tools that work with it. Thanks to @waveshare00 for sending the #pocketterm35 #cyberdeck we have a fully functioning tool and you can use it to build your own #raspberrypi OS. youtu.be/Mw0jyAdOaDw
