My wife is a prolific knitter. She has always wanted a sock knitting machine, and someday, I'll get her an antique. Until then, we found this 3D printed machine, and thought we'd give it a whirl.

This video is part 2 of ROS on Steamdeck - using ROS web bridge. I'm going to share the ROS2 version of the WebRTC ROS node for efficiently rendering video remotely on a web browser.

In this video, I'm revisiting ROS on Steamdeck - using ROS web bridge & a web application for teleoperating Robots which is compatible with many other devices - including iPhone, Android, PinePhone, and your favorite Cyberdecks.

Decided to post instead of rerecord.

In this video, I'll share how NOT to build a Motor ROS node, because sometimes you just need it to work, not work "correctly". This is a basic node for the Sparkfun Qwiic motor controller which directly consumes cmd_vel messages.

In this video I share some information about the InvenSense ICM 20948 Qwiic Breakout board by Sparkfun, a ROS node which uses the Wiring For ROS library to enable the Sparkfun Arduino library on Jetson and Raspberry Pi. I also discuss IMU Tools by CCNY to visualize and filter IMUs, and touch a little on Transform Trees to set up the next video.

In this video I share some information about pointclouds and a ROS2 node for the ST Micro VL53L5CX sensor with a Sparkfun Qwiic dev board and thre Sparkfun Arduino driver.

In this video, I'm going to share installing ROS2 on a Steamdeck using the RoboStack distribution of ROS. Steamdeck is a game console produced by Valve which has a compelling form factor for the teleoperation of robots and drones. The Steamdeck runs a distribution of Linux which is supported by the RoboStack project which uses the Condaforce package manager to distribute a build of ROS for various platforms - including Mac, Windows and Linux.

In this video I introduce "Wiring for ROS2" a side project to implement Arduino Style APIs, allowing you to use Arduino libraries produced for sensors, actuators or algorithms on computers with exposed headers like the Nvidia Jetson Nano or Raspberry Pi. To demonstrate using the library, I bring up a ROS node which implements the Sparkfun BME280 Qwiic sensor. The ROS2 Wiring template is available at https://github.com/polyhobbyist/ros_wiring_template. If you are interested in using ROS2 on a Microcontroller, which offers "real-time" support - definitely check out https://micro.ros.org/.

In this video, I'm sharing my ROS2 based BB-8 build. I've been fascinated by the BB-8 drive mechanism ever since the first trailers for Star Wars: The Force Awakens were released. My build is based on contributors in the BB-8 Builder's Club. My ROS Components for this build are available at https://github.com/polyhobbyist. NOTE: This video is not monetized by me.

In this video, I share how I set up my environment for working with the Jetson Nano on the Sparkfun Jetbot and other robots.

In this short video, I introduce the Sparkfun Jetbot and the components I'll be using for the build.

In this video, I'm going to share a few concepts which I hope will demystify ROS2, and set the stage for the rest of the series

Getting started with ROS2 and Robotics can be daunting. In this series of videos, I'm going to walk through working with ROS2 to build a simple mobile robot using an inexpensive robot platform with extensibility options.

In this video, I cover setting up the Visual Studio Code ROS extension for use with local development containers and over a remote ssh with remote development containers.

In this video, I cover setting up the Visual Studio Code ROS extension for use over a remote ssh connection.

In this video, I cover setting up the Visual Studio Code ROS extension for debugging both a single C++ node as well as multiple C++ nodes.

In this video, I cover setting up the Visual Studio Code ROS extension for debugging both a single python node as well as multiple python nodes.

In this video, I'll cover some of the ROS2 commands and UI available in the VSCode ROS extension.

In this video, I'll cover some of the ROS1 commands and UI available in the VSCode ROS extension.

In this short video I'll show how to install the visual studio code ROS extension on Linux. I'll also demonstrate options for selecting your ROS distribution.

In this video, I'll extract the master from the silicone mold, then cast.

In this video I create a hardshell for the mask. I don't end up using it as the silicone holds up quite nicely to slush casting, but it is an interesting activity.

In this video I'm (trying) to use Free Form Air, a two part foam epoxy. It didn't work.

In this video, I'm starting silicone mold and registration marks

In this video, I'm finishing up the silicone mold and working on the hard shell.
