Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Jcode-Bluetooth

码上掘金操作蓝牙智能设备。

已支持设备

逐步添加中...

使用方法

控制Playbulb智能LED

import {Playbulb} from 'https://unpkg.com/[email protected]/dist/jcode-bluetooth.js';
const device = new Playbulb();
const button = document.querySelector('button');
function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}
button.addEventListener('click', async () => {
  await device.connect();
  let hue = 0;
  while (true) {
    await device.setColor(`hsl(${hue}, 100%, 50%)`);
    hue = (hue + 1) % 360;
    await sleep(100);
  }
});

控制Pixoo系列像素板

因为Pixoo系列像素板的蓝牙协议是SPP,浏览器Web Bluetooth只支持GATT,所以需要启动本地HTTP服务做一个代理。

准备好设备,通过手机蓝牙调试工具查看设备地址,然后clone本项目到本地,安装依赖后启动server服务:

npm install && npm run server -- <设备MAC地址>

接着就可以在Web上编写代码了,Pixoo对象提供了可操作的canvas对象,你可以直接操作这个对象,绘制内容会自动同步到设备上。

import {PixooMax} from 'https://unpkg.com/[email protected]/dist/jcode-bluetooth.js';
const p = new PixooMax();
const ctx = p.canvas.getContext('2d');
ctx.fillStyle = 'green';
ctx.fillRect(8, 8, 24, 24);
