Last April I shared about my Resonate project here (https://news.ycombinator.com/item?id=43694157) A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube). This year's work, which I recently presented at this year's ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are…

We built the smallest dual-band aircraft trackerfrom $48/mo▲95I grew frustrated with closed source ADS-B receivers a few years ago, and wanted to build a true low cost embedded ADS-B receiver from scratch for low power applications. I ended up developing a custom radio frontend that uses RP2040 PIO for Mode S preamble detection and demodulation, and also released the first open soruce implementation of UAT decoding on an RF MCU from TI (which works somewhat beyond the publicly stated specs for the chip). Today, ADSBee is a fully featured dual-band ADS-B receiver, with Mode S, ADSB, UAT ADSB, UAT TIS-B / FIS-B, a ton of configurable reporting…

A pager▲104Hello HN, I basically don't use notifications for anything. The noise is too much. Slack is too loud. Email is too slow. But sometimes you do need a note in your face. I found myself missing 1990s pagers. I wanted a digital equivalent - something that does one thing: beep until I ack it. So I built UDP-7777. Concept: - 0% Cloud: It listens on UDP Port 7777. No accounts, no central servers. You don't need Tailscale/ZeroTier/WG/etc, it's just easy for device sets. - CAPCODES: It maps your IP address (LAN or Tailscale) to a retro 10-digit "CAPCODE" that looks like a phone number…

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…
