将照片转换为十字绣图案和 DMC 线号及 PDF。

我妈要把我家猫绣成十字绣，找不到合适的图纸工具，于是自己写了一个 起因：我妈绣了十几年十字绣，拿着我家猫的照片问我"这玩意能不能变成图纸"。找了一圈现成工具，不是要注册就是要订阅，导出还带水印，于是一怒之下自己撸了一个 → https://crossstitchpatternmaker.app 先说原理，免得显得像个套壳：照片降采样到网格 → 用 CIELAB 空间的 Delta-E 色距匹配到 454 个真实 DMC 线号 → 输出带符号和绞数估算的 PDF 。 技术栈：TanStack Start + Cloudflare Workers + D1/R2 。 但我妈嫌自动配色不如她手挑的线准。程序员 vs 一线业务用户，果然是普世矛盾。 欢迎拍砖，尤其是颜色匹配这块，总觉得还能再准一点，有大佬有相关图片转换算法的也欢迎分享讨论~

Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast. It ended up helping him a lot more than I expected, so I kept expanding it, added a bunch of other

计算抖音币成本，估算主播直播礼物收益。

做了一个海外 TikTok 直播打赏收益的计算器 大家好，最近关注到海外 TikTok 直播打赏很火，很多主播正在靠直播礼物默默赚钱。不过观众花了多少钱、平台抽走多少、主播实际能拿到多少，计算起来并不直观。 所以我做了一个 TikTok Coin 收益计算工具。 地址： https://coinvaluecalc.com/ 这是什么？ TikTok 观众先购买 Coins ，再用 Coins 给主播赠送礼物；主播收到礼物后，会获得对应的 Diamonds , 再用 Diamonds 转化为收益。 工具输入 Coins 数量，工具就能估算观众的购买成本、TikTok 平台费用，以及主播最终可以获得的收入。 特点： ✅ Coins 、Diamonds 和美元快速换算 ✅ 区分观众花费与主播收益 ✅ 收录常见 TikTok 直播礼物 ✅ 完全免费，无需注册，即开即用 不同地区和充值渠道的价格可能不同，计算结果仅供参考。欢迎大家体验和提建议。
