Show HN: Q-Octo – We reinvented the wheel with a compact endurance rover Hello, inspired by Q-Whex [1], we built Q-Octo, a compact rover with eight quasi-wheels (160° cut out). The wheel design enables the rover to climb over larger objects while rolling smoothly on flat ground. Q-Octo uses four drill batteries, two Xiaomi Cybergear motors (vs 6 motors for the Q-Whex), two Raspberry Pi Pico’s (one with WiFi), a Pimoroni Pico display, and a variety of 3D-printed & laser cut pieces for the body. The rover can be configured via its Wi-Fi access point as it hosts a web socket server with mDNS and a captive portal. Messages are encoded via Flatbuffers. It is driven manually via a radio transmitter with a custom UI that we made using Lua & EdgeTX. Autonomous navigation can be achieved by hooking up a single-board computer via UART. We are four students who built this as one of four modules in the final semester of our undergraduate degree. Search ELEC6212 on YouTube to see what our peers got up to. Britannio, Josh and Niall studied Computer Science, and Alfie studied Electronic Engineering. Everything is open-source and we made a Discord server [2] to support people interested in creating their own Q-Octo. Nonetheless, we intend to refine the design and commercialise Q-Octo this summer if there is sufficient interest. Would you like one? Are you using a comparable rover? Advice here would be useful :) A YouTube video with development progress and our test runs: https://www.youtube.com/watch?v=2PIdxYJO_Ck [1] https://www.youtube.com/watch?v=UJHbiZUROM8 [2] https://ift.tt/zBo8n1G https://ift.tt/1V5PexY June 18, 2024 at 11:24PM

Show HN: Interactive exercises for GNU grep, sed and awk https://ift.tt/OxeFwah

Show HN: Interactive exercises for GNU grep, sed and awk Hello! For the past few months, I've been using a Python framework called Textual to create TUI apps for interactive exercises. Released the app for GNU awk earlier today, so thought I'd create a post here. If you already know how to manage Python packages, you can use the following command to get all the three apps: pip install grepexercises sedexercises awkexercises `pipx` should also work, but I haven't tested it. The GitHub repo has the source code as well as more detailed installation instructions. You can use alternative CLI tools to solve these exercises as well. For example, Perl instead of GNU awk or ripgrep instead of GNU grep and so on. Hope you find these TUI apps useful. I'd highly appreciate your feedback. Happy learning :) https://ift.tt/Hp9kFEi August 17, 2023 at 05:13PM
