Inspiring a new generation of tinkerers and programmers is what the Raspberry Pi, a tiny DIY computer that fits in the palm of your hand, is all about.

A simple Google search brings up thousands of cool Pi projects and hacks; people love the little $35 computer. To date, more than 5 million units have been sold since the Pi debuted three years ago. A handful of different models exist now, but the spirit remains the same: Go out and hack it into something awesome.

Earlier this year, the Raspberry Pi Foundation released the Pi 2 with a 900MHz quad-core processor, which is six times more powerful than the original Pi. The Pi 2's also got double the RAM (1GB) and four USB 2.0 ports, two more than before (though none are USB 3.0).

It's really a PC

At the most basic level, the Pi 2 is a functional PC. Load an operating system onto a memory card, connect it to a TV or computer monitor with an HDMI cable, plug in a wired USB keyboard and mouse, attach an Ethernet cable, add a Micro USB cable to a power source, and you'll be surfing the Internet in no time.

It can work with a wireless Bluetooth keyboard and mouse and connect to the Internet over Wi-Fi, but you’ll need to buy a Bluetooth receiver and Wi-Fi USB adapter in order to do so.

As a computer, the Pi 2 is about as powerful as a netbook. (Remember those?) It's underpowered and you can't really juggle more than a few tabs in a web browser — but it all works, as long as you're willing to wait a few seconds longer for things to load.

Time for some fun

The Pi is all about getting your hands messy and wrangling with a little (or a lot) of code. I set out to do something fun with the Pi 2.

One of my all-time favorite Pi projects is this Pi-powered, voice-controlled, face-tracking R2-D2:

But my dreams were crushed when I couldn’t find any instructions online, and I’m not savvy enough to draft up my own design. Not to mention, I only had a $50 working budget to buy parts outside of the Pi 2 itself.

After sidelining the Pi 2 for a few months, I finally decided to make a 3D-printed spy camera bow tie inspired by this Make: project. It's techie, geeky and a conversation starter. Win, win, win.

You can build your own spy camera bow tie by following the step-by-step guide in the gallery below:

How to: Raspberry Pi 2-powered, 3D-printed bow tie spy cameraGather your supplies

Here's a list of everything you'll need to build your own Raspberry Pi 2-powered bow tie spy cam: portable battery pack, microSD card with SD card adapter, Wi-Fi adapter, Ethernet cable, Micro USB cable, Raspberry Pi 2, 3D-printed bow tie (you can swap this from other materials if you want to) and Raspberry Pi camera module.

The Raspberry Pi 2 is a computer, but it doesn't have any software to control it. For this project, you'll need to download motionPie from here and unzip it. Take your microSD card and insert it into an SD card adapter, and then insert it into your computer. PC users can use Wind32DiskImager and Mac users can use ApplePi-Baker to "burn" motionPie to the memory card.

Image: Luke Leonard/MashableStep 2: Plugging in the hardware

The next step is to connect all the cables. Plug in the Ethernet cable and Wi-Fi USB adapter.

Image: Luke Leonard/MashableStep 3: Connect the camera

Insert the Pi Camera Module's ribbon cable into the camera port (it's right next to the HDMI port and labeled "Camera")

Image: Luke Leonard/MashableStep 4: Give it some power

Connect a Micro USB cable and connect to a portable battery pack or power adapter. (If you own a phone charger, that'll work perfectly.)

Image: Luke Leonard/MashableStep 5: Wi-Fi setup

With the Ethernet cable connected to the Pi 2 and your router, use the Fing app for iOS and Android to find out what the Pi 2's IP address is. It should show up as "Raspberry Pi Foundation" in the app.

Once you've got the IP address, type that into your web browser (make sure it's on the same Internet network) and then click the key icon in the upper left.

From there, click under "Network" and toggle Wireless Network to "On." In the "Wireless Network Name" box enter your Wi-Fi network and in the "Wireless Network Key" box enter the password for it.

Unplug the Ethernet cable from the Pi 2. Open the Fing app again and this time look for the IP address for the Wi-Fi adapter. Our Wi-Fi adapter is made by Edimax, so it shows up as "Edimax Technology." Use this new IP address to log into your wirelessly-enabled Pi 2.

Find a 3D bow tie design (we used this one from Thingiverse and then scaled it to a larger size. Use a 3D printer (we used a MakerBot) to 3D-print your bow tie.

Image: Raymond Wong/MashableStep 7: Attach camera module to bow tie

Since we 3D-printed out our bow tie, we needed some sticky putty to attach the camera module. You can use tape or glue if you want.

Image: Luke Leonard/MashableStep 8: Test your new creation

Navigate to the Raspberry Pi 2's IP address from Step 5 on a computer or phone to see if the camera works.

Image: Luke Leonard/MashableStep 9: Wear your bow tie!

Hide all of the components inside of your shirt and snake the micro USB cable attached to the battery pack into your pants pocket. Nerd out!

Image: Luke Leonard/MashableThe DIY spirit is strong

This was my first Pi project, and after finishing it, I must admit: It was a lot of fun.

As a kid, I used to open my dad's VCR, cassette tape player and radios, and then try to "fix" them by putting them back together after disassembly.

With the $35 Raspberry Pi, we built 3D-printed bow tie spy camera.

Image: Luke Leonard/Mashable

If I was able to put them back together in working condition, he never found out. When I couldn't, I'd get yelled at, but at least I'd then get the broken parts afterward so I could glue them to my Erector sets and build my own gadgets. My Inspector Gadget creations never worked, but like any kid, I pretended they did.

With a Pi, I no longer need to pretend. Awesome inventions are just a Google search tutorial away. And unlike other online forums where discussions between users can get nasty fast, many of the ones I perused were cheery and friendly with users that are happy to provide help.

Raspberry Pi 2The Good

Super inexpensive ($35) ? 4 USB ports, 2x more RAM ? Ethernet port ? Wi-Fi

The Bad

Doesn't include USB power adapter/MicroUSB cable or an HDMI cable

The Bottom Line

For $35, the Raspberry Pi 2 is an awesome little DIY computer that can be hacked into almost anything.

Bonus: Spying on friends with the bow tie

树莓派二代—如何打造一款3D打印领结式偷拍照相机

UTCRaspberry PI 2：如何建立一个3D打印领结间谍相机[导读]由黄百鸣

混搭Choicehighlights我们测试过的andwould推荐给别人的产品和服务。认为这是招人喜欢，收藏，+ 1'ed和牵制。

鼓舞人心的新一代能工巧匠和程序员的是什么树莓派，适合在你的手掌一个微小的DIY电脑，是所有有关。

一个简单的谷歌搜索带来了数以千计的酷皮项目和黑客攻击;人们爱的小$ 35个计算机。迄今为止，已有超过500万单位已售出，因为丕推出三年前。少数不同型号的现在存在的，但精神是一样的：走出去，本事到的东西真棒。

另请参阅：17简单的工具黑客帮你钉任何项目

今年早些时候，树莓派基金会发布了PI 2用900MHz的四核处理器，这比原皮六倍更加强大。该PI 2的也得到了双倍的内存（1GB）和4个USB 2.0端口，比前两个（虽然没有一个是USB 3.0）。

这的确是一个PC
在最基本的层面上，皮2是功能的PC。加载操作系统到存储卡，将其连接到电视或电脑显示器用HDMI连接线，插上有线USB键盘和鼠标，连接以太网电缆，添加一个Micro USB数据线连接到电源，你会是上网冲浪，在任何时间。

它可以用无线蓝牙键盘和鼠标的工作，并连接到互联网通过Wi-Fi，但你需要购买一个蓝牙接收器和Wi-Fi无线USB适配器才能做到这一点。

作为一台电脑，郫县2大约是一样强大的上网本。 （还记得那些？）它的动力不足，你真的不能兼顾以上几个标签在网络浏览器 - 但它的所有作品，只要你愿意等待几秒钟长的东西加载。

时间对于一些乐趣
该皮是所有关于你的手凌乱和代码一点点（或很多）闹得不可开交。我开始做一些有趣的郫县2。

我的一个所有时间最喜欢丕项目是该PI供电，语音控制，面部追踪R2-D2：

但我的梦想被击碎了，当我找不到任何指示联机状态，并且我不是足够精明，起草了我自己设计的。更何况，我只有一个$ 50个工作预算到PI 2本身之外的买配件。

边缘化的PI 2几个月后，我终于决定做一个3D打印的间谍相机领结灵感来自这个品牌：工程。这是技术人员，怪异和话匣子。赢，赢，赢了。

您可以通过以下的一步一步的指导下面的画廊建立自己的间谍相机的领结：

如何：树莓派2供电，3D打印领结间谍相机

收集你的用品

这里的一切的名单，你需要建立自己的树莓派2供电领结间谍凸轮：便携式电池，microSD卡与SD卡适配器，无线网络适配器，以太网电缆，微型USB数据线，树莓派2， 3D打印领结（你可以，如果你想从其他材料交换本）和树莓派相机模组。

第3步：连接相机

将皮相机模块的带状电缆插入相机端口（它旁边的HDMI端口，并标有“相机”）

Image: Luke Leonard/Mashable

第4步：给它一些权力

连接一个微型USB电缆和连接到便携式电池或电源适配器。 （如果你拥有一个手机充电器，这会很好地工作。）

Image: Luke Leonard/Mashable

第5步：Wi-Fi设置

随着以太网电缆连接到PI2和路由器，使用Fing头应用程序适用于iOS和Android找出丕2的IP地址是什么。它应显示为应用程序中的“树莓派基金会”。

一旦你的IP地址，输入到网页浏览器（确保它是相同的互联网络），然后单击左上角的钥匙图标。

从那里，点击下的“网络”，并切换无线网络为“开”。在“无线网络名称”框中输入您的Wi-Fi网络，并在“无线网络密钥”框中输入密码了。

拔掉皮2.打开以太网电缆再次将Fing头的应用程序，这一次寻找的Wi-Fi适配器的IP地址。我们的Wi-Fi适配器是由爱迪麦斯而成，因此它显示为“的Edimax技术。”使用这个新的IP地址登录到您的无线功能PI 2。

第6步：3D打印领结

查找3D蝴蝶结的设计（我们用这样一个来自Thingiverse，然后缩放到更大的尺寸。使用3D打印机（我们用MakerBot）到3D打印您的领结。

Image: Raymond Wong/Mashable

第7步：安装摄像头模块领结

由于我们的3D打印出我们的领结，我们需要一些粘泥附着在摄像头模块。你可以用胶带或胶水，如果你想要的。

Image: Luke Leonard/Mashable

第8步：测试新的创造

导航到树莓派2的IP地址从一台计算机或电话上的第5步，如果相机的作品看。

这是我第一次丕项目，完成后，我必须承认：这是一个很大的乐趣。

作为一个孩子，我用开我爸的录像机，盒式磁带播放器和收音机，然后尝试“修理”他们被拆卸后，把他们重新走到一起。

随着$ 35个树莓派，我们建立了3D打印领结间谍相机。

图片：卢克·伦纳德/混搭

如果我能够把他们重新走到一起在工作状态下，他从来没有发现。当我不能，我会挨骂了，但至少我会再拿到破之后的部分，所以我可以胶水他们到我的竖集和建立自己的小工具。我的神探的作品从来没有做过，但像所有孩子一样，我假装他们做到了。

使用PI，我不再需要假装。真棒的发明仅仅是谷歌搜索教程了。不像其他在线论坛上，用户之间的讨论能够得到讨厌快，很多的那些我细读是愉快和友好与乐于提供帮助用户。

树莓派2The好
超级便宜（$ 35）？ 4个USB接口，2倍的内存？以太网端口？无线上网

坏
不包括USB电源适配器/ microUSB数据线或HDMI线

底线
对于$ 35，树莓派2是可以侵入几乎任何一个真棒小DIY电脑。

奖励：刺探朋友领结
