Just released my second iOS app called Wholegrain! It’s a film emulation and editing app with custom designed gain synthesis to give photos the look and feel of film 🎞️

「Wi-Fi 6 といっても2.4GHz帯だけなんでしょ?」とESP32-C6 を侮っていましたが、OFDMAのおかげで端末が多くても通信が詰まらなかったり、TSFでμsオーダーの同期ができたりでとても便利なことに気がつきました。 無線での同期（USBは電源だけ）で0.1msの桁まで撮影時刻が一致します。

Crazy how much easier it is to use these Chinese Pi clones with LLMs now. I’ll never use a Pi again

I released this #AI tool that generates and implements #biquad filter in your #Verilog module, you just need to describe the filter and it will be added to your module. Test it and give your feedback! github.com/controlpaths/biqu…

The RF world is insane. Researchers recovered AES-128 keys from a Bluetooth chip by listening to its own antenna from 10 meters away. Crypto-engine switching noise couples into the RF chain, rides the 2.4 GHz carrier, and leaks out as radio.
