Products that do what I built a system to drive my RC car from anywhere in the world does
Wanted to share a project I've been working on. Basically lets you drive an RC car remotely over the internet with live FPV video. I'm arranging outdoor time attack tournaments with friends, somewhere in woods or in the open field. The setup: - Raspberry Pi Zero 2W mounted on the car with a wide-angle camera - ESP32 on the transmitter generating joystick voltages (needed because ARRMA's 2-in-1 ESC/receiver has no accessible inputs) - Cloudflare for the networking magic (TURN, Tunnel, Workers) - Browser-based controls - works on phone or desktop What it does: - ~100-200ms control latency…

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…

This is a projected I started that blends both the fun of playing a split screen multiplayer driving game and controlling real rc cars. The cars can also be controlled via bluetooth gamepads and is meant to be easily hackable.

I have been taking Andrew Ng's Machine Learning course. The lecture module on Neural Networks ends with an intriguing video of the ALVINN autonomous car driving itself along normal roads at CMU in the mid 90s. I was inspired by that video to see what I could build myself. A link to my incomplete write up was posted a couple of weeks ago (ouch!) but I finally finished it and open sourced the code tonight (so you can build your own self driving car). What do you think? http://blog.davidsingleton.org/nnrccar https://github.com/dps/nnrccar

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!

Still very much a work in progress, but really wanted to share this even in it's early state. Had heaps of fun building it to learn more about WebRTC.

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…

Hi HN, To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP/IP stack. I'm excited to share the result: my own from-scratch TCP/IP networking stack running directly inside the xv6-riscv (https://github.com/pandax381/xv6-riscv-net) kernel. The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine. Key features: - From-Scratch Stack: The core is powered by microps…

I built a software-defined radio transmission platform that runs on a Raspberry Pi Zero W. It spawns its own WiFi hotspot and serves a web UI — connect from any device and you have a portable RF signal generator with 12 transmission modes: FM broadcasting with RDS, FT8, RTTY, FSK, POCSAG paging, Morse code, SSTV image transmission, voice cloning via live mic, spectrum painting, IQ replay, carrier wave, and frequency sweeps. Everything runs through a browser interface. Upload audio files, type messages, configure frequencies, and transmit. The Pi's GPIO pin does the actual RF generation via…

This is the third camera I've designed/made around the raspberry pi parts/ecosystem. The repo has all the STL files, parts list, most wiring diagrams. The first one was the custom Pi Zero HQ cam which was featured on a Hackaday article/podcast. The modular version (aside from being able to swap cameras) mostly has the latest software. Recently I added the ability to process videos in the background (ffmpeg merges wav/mp4 files together). The camera uses crop-zoom-panning for dialing in shots with manual lenses. The menu is created by layering images/text with PIL.…

- This page is running directly on the Pico W in the stream, using microdot (but proxied out via cloudflare tunnel). - There's a buzzer that plays a sound as well but the stream has no audio. - There's a Pi Zero 2 W with a Camera Module 3 streaming the video. Streaming low latency video is painful. I tried mjpeg, Nginx+HLS/DASH, YouTube and Twitch. Twitch is definitely the easiest and best-performing. - There's still a few seconds delay between sending your message and the video updating.

I've never posted on ShowHN before, but I wanted to share my Xmas 2025 project; to try a new approach to controlling our kids screen time. This also involved massively over-engineering a solution in order to play with a shiny new gadget (and avoid the in laws at Christmas, obviously) I've shared some learnings on AI coding with embedded devices, and how I approached the product design/hardware selection side of things. The Web App is at https://screenie.org - and I'm Open Sourcing the device and web app code later today (links to follow on that site)

Hello Hacker News, My co-founder and I have spent the better part of years developing a completely hackable Home Automation toolset that runs on a Raspberry Pi, or any machine running Linux. With just a Raspberry Pi and a $45 Z-Wave dongle (https://www.amazon.com/Aeotec-Z-Stick-Z-Wave-create-gateway/...), you can run a complete home automation system! Our hub will support any Z-Wave or Z-Wave plus device. We are cloud hosted service that doesn't require you to purchase any proprietary hardware. Our hub software runs on NodeJS and is completely open source. We encourage…

The project identifies as "Your Raspberry Pi FM network". It uses a fork of the well-known PiFmRds as a backend to stream audio on FM radio. It allows the control of multiple pi units with a central server, that can also be temporarly hosted on google cloud shell or github codespaces.

http://picirus.com For Startup Weekend Tulsa, we created a small low-power appliance (built on Raspberry Pi) that you connect to your different cloud accounts -- Facebook, Flickr, Dropbox, etc. -- and it downloads a copy of all your stuff every night. I was thinking about all the people I love who share directly to the cloud, without a lot of planning for the case where their Facebook account gets hacked, their Dropbox account has a glitch, or one of these services they love goes out of business suddenly some day. We had a ton of fun building Picirus during Startup Weekend. I highly…

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

Greetings, HN! I have created a new kind of 360º video camera with GPS and live streaming capabilities. A device like this has never existed in this form factor or price point before. After launching on Kickstarter, it has gotten coverage in Techcrunch and Boingboing, and received 89% funding in the first 24 hours. I'd love to hear anyone's thoughts about the device, the Kickstarter campaign, and any ways of publicizing the campaign that I might be missing. I'm most interested in hearing anyone thoughts about how the Kickstarter page might be improved to boost conversions, as the clock is…

I always find myself frustrated by how many steps I have to take to video chat with someone online. There's always too much software to download and install, and too many accounts to remember. The high-end, high-price Cisco conferencing systems I've used are especially fragile. So I built Vidless in a weekend for myself, and I hope you find it useful too. Just create a room and share the link, and you'll be chatting in seconds. You can invite several people (I haven't really tested a max yet), and chats on Vidless are always private. Enjoy!
