Products that do what Q-Octo – We reinvented the wheel with a compact endurance rover does
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…

Found that you can actually run a 35B Qwen model on a Pi with very impressive intelligence and stability. Built connectors for car ODB to read all about car internals, and manufacturer's cloud service for stuff like changing AC or opening/ locking doors. Gave it info such as the full car manual. And then hooked it up with my other agents in our discussion room! So now it can answer car questions such as "when should I add oil and what kind of oil?" and help you fully offline, and when online talk with the agent family that includes all the most powerful models so they know how the car…

Kitten TTS (https://github.com/KittenML/KittenTTS) is an open-source series of tiny and expressive text-to-speech models for on-device applications. We had a thread last year here: https://news.ycombinator.com/item?id=44807868. Today we're releasing three new models with 80M, 40M and 14M parameters. The largest model (80M) has the highest quality. The 14M variant reaches new SOTA in expressivity among similar sized models, despite being <25MB in size. This release is a major upgrade from the previous one and supports English text-to-speech applications in…

I am not sure if this is fits the HN community, but I am posting it here if people are interested. This is the current iteration of the car: http://i.imgur.com/ko8YBh.jpg Details: I wrote a simple android app that streams the accelerometer data from the phone to the pi over a simple socket. The pi then uses this data to drive the DC motor and the servo motor. Tilting the phone to control the car feels very natural. In this[0] pic you can see the wifi dongle I've used. I am using Adafruit Occidental v0.2[1] as my OS because it has support for my wifi dongle. It also makes some hardware…

I made this 130 mile capable VTOL drone in only 90 days. It can fly for 3 hours on a single charge. That would make it one of the longest range and endurance 3D printed VTOLs in the world. This is the thing I'm most proud of building to date! Before this project, I was a total CAD, 3D printing and aerodynamic modeling beginner. I had only built and flown one VTOL before. SPECS Wingspan: 3.9 ft (1200 mm) Length: 2.5 ft (770 mm) Weight: 5.6 lb (2.55kg) Airframe: foaming PLA (Bambu PLA-Aero) and PETG structural parts printed on A1 printer, CFRP booms and spars Battery: Li-ion silicon anode…

I built a mechanical computer kit: https://whomtech.com/show-hn tl;dr: it's a cellular automaton on a "loom" of alternating bars, using contoured tiles to guide marbles through logic gates. It's not just "Turing complete, job done"; I've tried to make it actually practical. Devices are compact, e.g. you can fit a binary adder into a 3cm square. It took me nearly two years and dozens of different approaches. There's a sequence of interactive tutorials to try out, demo videos, and a janky simulator. I've also sent out a few prototype kits and have some more ready to go. Please…
