Show HN: Mira – Open-source and self-hosted AI code reviewer Hey HN, I'm Jay, co-creator of Mira. An open-source, self-hosted AI code reviewer where you BYOK (bring your own key). Local models are getting really good. Hosted frontier models are getting really expensive. So, we built Mira. Mira has some snazzy features too: - It's really fast at reviewing. Average is 77s compared with Greptile's 5 minutes. Your PRs aren't going into a queue on a cloud somewhere. - Mira performs a blast radius and see what damage will be done with code change. - Learns your codebase's patterns from the repo itself and enforces them without a config file. - It's self-hosted, so your code never leaves your infrastructure. Bring your own model - OpenAI, Anthropic, or a local LLM behind your firewall. We're really active, and looking for active contributors. Come join us in our discord! https://ift.tt/wSJNbhD Thanks, Jay https://ift.tt/wSJNbhD June 17, 2026 at 03:23AM

Show HN: Capacitor Alarm Clock https://ift.tt/1LvUcms

Show HN: Capacitor Alarm Clock I made an alarm clock that blows up capacitors to wake you up. There are more details on the Github repo but it's made from an esp32-c3 as the microcontroller, with 3 capacitor slots. There are relays on each capacitor slot to put 15v reverse voltage on the capacitor, with 5.1 ohm resistors on each slot for current limiting in case the capacitor shorts out. I also chucked in an SSD1315 OLED to show the time and a menu to configure it, although there's a web UI as well. The esp32 also means you can fetch the time from NTP. It also functions as a small heater since I used LDOs to step down 15v to 3.3v for the esp32, I was lazy and didn't use a buck converter circuit :) https://ift.tt/FtGuyc8 June 14, 2026 at 01:19AM

Show HN: High-Res Neural Cellular Automata https://ift.tt/qCI24F7

Show HN: High-Res Neural Cellular Automata Neural CAs model self-organizing pattern formation. Now they can generate patterns at HD resolution in real-time, enabled by turning each CA cell into a Neural Field. Try 3 demos: grow a pattern from a seed (and damage it, it heals), synthesize PBR textures that can regenerate, or create 3D textures like clouds. https://cells2pixels.github.io/ June 16, 2026 at 11:28PM
