@karminski3 现在再看牙医的这nuc测试平台是真好用……天天拔插pcie aic的场景就得是这样

感觉这个项目可以直接归档入土了，有人用RUST重写了整套驱动，还把卡上的Linux弄成了7.2😨这怎么打

看到了个Fable5.1弄的神奇项目, 是一个标签打印机的固件, 作者说他在速卖通上买了个热敏标签打印机, 然后打印机耗材用光了, 他就买了点第三方的热敏纸. 结果这个标签打印机很鸡贼, 耗材是有RFID的(让我想起了空气净化器的滤芯), 检测到不是自家产品, 就降速然后降低打印质量.

由于是RFID, 于是大家的人肉破解方法是把用光的耗材的卷轴(类似卷纸芯的那根塑料轴，里边有RFID芯片), 放到打印机旁边, 然后把第三方耗材的卷轴拆掉. 这样打印机就只能感应到原厂塑料轴, 就能继续打印了.

作者气不过于是用Fable-5.1尝试破解这个打印机固件, 然后经过几次刷机后, 就成功了.

我看了下repo细节, 有挺多好玩的地方, 首先Fable-5.1成功推导出了控制打印浓度的公式: darkness=renderer_input×coefficient, 然后定位了打印浓度在内存中的位置, 然后甚至利用了 Cortex-M0 汇编代码洞跳转技术把浓度重映射的动态逻辑缝合了进去, 彻底绕过了降速和降质限制.

比较黑色幽默的是整个过程 AI 负责搞定高难度的 ARM 逆向, 数学推导和汇编注入, 而人类由于长了眼睛和手, 于是负责提供物理执行力, 也就是按电源键和看纸上的字够不够黑.

从目前来看 AI 正在把逆向工程这种原本专属于极客的"重工业技术"彻底平民化了. 照这个趋势发展下去，硬件厂商精心设计的用来搞垄断的那些防伪和硬件锁啥的, 在人人可用的代码 Agent 面前, 基本就跟纸糊的一样了.

Stumbled across these cursed Surface Mount LED spacers when looking for something else and felt like sharing.

Neat DIY ESP32-S3-based air quality monitor.
https://t.co/QX8OlF398E

Project Aura is made of off-the-shelf electronics parts, including a Waveshare ESP32-S3 board with a 4.3-inch touch display, and a range of sensors and breakout boards from Adafruit and Seeed Studio for PM1, PM2.5, PM4, PM10 particle levels, CO2, VOC, NOx, and formaldehyde (HCHO) levels, as well as temperature, humidity, and pressure data.

No soldering is required as everything is connected through wires. Users still need to use a 3D printer for the enclosure, and the LVGL-based firmware has a neat user interface compatible with Home Assistant.

@giammaiot2 Nice. Reminds me of the sentry gun computer from Aliens
