每周一次，我们收集一些优秀的读者提示，并与大家分享。本周我们将介绍如何使用iPhone作为睡眠监视器，在最佳时间唤醒你，如何用数码相机测试遥控器，以及一种**发光复活节彩蛋的聪明方法。

用iphone追踪你的睡眠周期

尼科看到我们的睡吧。我今天早些时候发帖，并用iPhone提示写道：

While Sleepyti.me is pretty neat, what’s really awesome is using your iPhone as a sleep sensor. I’ve been using Sleep Cycle for a few years now. It’s an app that uses the motion sensors in your iPhone to detect when you rise in and out of deep sleep based on your movements. You tell it what time (round about) you want to wake up and it wakes you up at the best possible moment in your sleep cycle. So if I tell it I want to get up at 8AM and 7:15 is actually a perfect time for me to wake up feeling refreshed, the alarm will go off then to wake me when I’m out of deep sleep. It’s sweet! Best buck-for-an-app purchase I ever made.

尼科，这是一个相当漂亮的应用程序。我们很乐意听到读者在他们的Android**上使用类似的东西！

用数码相机测试你的红外遥控器

汤姆写了一个简单的诊断测试：

The other day I was trouble shooting my universal TV remote. Something fishy was going on and I needed to start from the basics and move up. I replaced the batteries but there seemed to be no signal being sent to the television (this particular remote doesn’t have any sort of indicator on it). To test and see if the remote was actually beaming anything out, I pointed it at my **artphone’s camera (I think this should work with just about any digital camera) and I was able to see the infrared output of the IR LED on the front of the remote! Score!

很聪明，汤姆。我们将把这个记录在我们每一个不断增长的关于偷偷摸摸的故障排除技巧的Rolodex里。

便宜的复活节彩蛋

米莉用自己动手做的技巧写道：

Loved the LED Easter Egg post from earlier today, but not everyone has a cache of LEDs laying around. I followed a tutorial I found on the web that kept things simpler… instead of batteries and LEDs, you just stuff the eggs with slender glow sticks from the Dollar Store.

作为一个最后一分钟的黑客，使用发光棒绝对比通宵使用一些发光二极管容易。谢谢分享！
