树莓派打造淡入闹钟，让电台轻轻的叫你起床

 原文地址：https://www.hscbook.com/article/raspberrypi-alarmclock/，对作者表示感谢
16年入了一个树莓派B+版折腾了一下就放在角落里积灰了，我这天天总睡懒觉的人被冰冷的闹钟吓得激醒是非常痛苦的，某天打扫房间发现了被我打入冷宫的树莓派就顺手拿出来打造成淡入闹钟+晨起天气预报+晚间电台播放。

简介

· 早上7点定时从低音量的青苹果电台（早上电台没有节目，只有音乐）逐步提升音量轻轻的音乐声叫你起床，3分钟后语音播放今天的天气预报，一个小时后结束播放。
· 晚上10点开始低音量播放青苹果电台（现在电台播放情感节目）提醒你准备碎觉了，最后一个小时候结束播放并对你说声晚安！

准备工作

必要材料

1.男/女，聪明大脑一块
2.五指手一双
3.能上网的树莓派一个
4.音响一套

给予执行权限


chmod 775 /home/Morning/vlc/*



chmod 775 /home/Morning/Morning.sh



chmod 775 /home/Morning/Evening.sh

添加计划任务

注意：请确定树莓派的时区是在中国，树莓派默认的时区不是中国。并确定时间是否正确

执行：



export EDITOR="/usr/bin/nano" ; crontab -e



输入：



30 07 * * * sudo /home/Morning/Morning.sh



00 22 * * * sudo /home/Morning/Evening.sh
执行时间视需求而定，比如你想早上8点叫你起床，晚上9点播放电台就修改为

00 08 * * * sudo /home/Morning/Morning.sh



00 21 * * * sudo /home/Morning/Evening.sh

Interview with Steve Jobs, WGBH, 1990

Interviewer: what is it about this machine? Why is this machine so interesting? Why has it been so influential? Jobs: Ah ahm, I'll give you my point of view on it. I remember reading a magazine article a long time ago ah when I was ah twelve years ago maybe, in I think it was Scientific American . I'm not sure. And the article ahm proposed to measure the efficiency of locomotion for ah lots of species on planet earth to see which species was the most efficient at getting from point A to point B. Ah and they measured the kilocalories that each one expended. So ah they ranked them all and I remember that ahm...ah the Condor, Condor was the most efficient at [CLEARS THROAT] getting from point A to point B.

Apple's One-Dollar-a-Year Man, By Steve Jobs, 2000

(FORTUNE Magazine) – Now that Steve Jobs has showed his hand on Apple's Internet and system software strategies and dropped the "interim" from his title, other questions loom. He's always denied it, but isn't it true that his old company, Next, did wind up taking over Apple? Will there ever be an encore to the 15-year-old Macintosh? Short of that, does Apple have any plans to jump into the "Internet appliance" fray? Will Apple ever build computers for business people again? And what, pray tell, does Steve think of all these young Internet zillionaires? Let's ask. Practically every technology that your old company, Next, possessed when Apple acquired it in 1997 is now being used by Apple in some strategic way. This must seem like sweet vindication.  The thing about Next was that we produced something that was truly brilliant for an audience that our heart really wasn't into selling to--namely, the enterprise. I suppose if you were wr...

Steve Jobs: `There's Sanity Returning', 1998

Nobody can doubt the charisma of Steven P. Jobs. The interim CEO of Apple Computer Inc., who returned to the company last July after his ignominious 1985 ouster, has brought back his legendary vision, impatience, and infectious passion for the Macintosh. Jobs spoke to Business Week Correspondent Andy Reinhardt in Apple's stark, fourth-floor boardroom, just after the company rolled out its new software strategy on May 11. Note: This is an extended, online-only version of the Q&A that appears in the May 25, 1998, issue of Business Week. Q: Now that you've introduced the new, bold-looking iMac, are you going to do some radically different products? A: There's a lot of talk about such things -- about handhelds, set-top boxes. A lot of computer companies have been searching for a consumer product. My view is that the personal computer has been the most successful consumer product of the last 10 years. What we have to do, what the industry stopp...
