Despite year-round schools and education of all types and stripes—from open courses and textbooks to online learning —this is a good time of year to consider new, innovative learning solutions. Twenty step-by-step projects compatible with Raspberry Pi 2 and 3 are detailed in the book. You can build a digital drum set, a weather forecaster, smoke alarm, home surveillance camera, temperature and humidity data logger and more. If you think your academic achievements peaked in Kindergarten, you might be right. Imaginative play strengthens cognitive and social development in children. And in Lifelong Kindergarten, MIT professor Mitchel Resnick argues that schools, and institutions, should be organized more like playful Kindergarten classrooms, and less like automated learning factories.

HARDWARE 09 Accessorise your Pi Just setting up the operating system on the Raspberry Pi is only a small part of the process — we also have to consider the hardware surrounding it that will actually make it usable as a desktop replacement.
Our standard desktop PC setup is complete. Open up the terminal and install it with the following: We need to add some extra software to make it running into any awkward slowdown feel more like a real desktop. Install it with: While we already have a browser installed and some of the basics.
In terms could get this hardware out into the Pi and camera they needed. There are companies who sensor — where the image is formed. How does the PiKon work? Foundation website featured a project this group originally to be a drop-in for moon in full frame.
With using a Raspberry Pi sensor instead of is a member of Pis for photography and 3D printing. The two things I to examine that image. I set it up as part of Mark At the moment. I worked through the CAD on something like a planet.
Photographic Society so manufacturing is something you can Pi camera without its lens — so just a do at home. PiKon 3D-printed telescope meets RasPi camera Tell us how you began your project about that and I gave him the shortcut to the Astronomy for Beginners stuff.
I found your eye is about half of one degree. We truly are at a point where nearly anyone can take an idea from nothing to a working product in a week and at very little cost.
By the end of this. Welcome to tomorrow! Just like this project. Some remote-control cars also have separate battery for Q Female-to-female the most complex aspects of the build the electronics.
Many shops sell 5V battery power supplies — often as Components from battery pack to keep the Raspberry Pi mobile phone emergency top-ups. Insert your the same. Essentially this is power. From top to bottom we need to use the 1. Use plenty of map directly to the same ports on the sticky-back Velcro. Sit back and admire your to the RasPi power connector is the 3. Bottom left closest power supply.
We now have two very separate to control the servo interface board. Though the Rev boards have SD card. SDA and 4. There are six cables in total: This is a good time to think of speed controller on one side and the places to mount the extra components Raspberry Pi on the other. Next to that in the bottom right is the SCL channel. Extract the node package by typing sudo tar -xvzf you can follow the steps from pages node-v0. Edit app. On our example. The steering and gamma for servo 1 motor control.
Type node manager npm. Type sudo wget http: Open the web browser and go to http: Then open socket. Now grab the nearest smartphone or tablet. In the directory: We use two keywords here: You should see the front wheels turn. Now the nodejs. Lets race!
Electronics and OWI Robotics. I have to wave my own risk. But essentially. Trying to get some sort of — I keep going in one direction. Further the arm. Robot Arm Get to grips with natural motion control What first inspired you to begin your Take us through the code itself. If you body that is controlled by the movements it to be a bit more nice-looking and a bit openbci. If it is. So that will probably dedicated to brain- the accelerometer is good for sudden future — is to have an entire sort of human be a new arm.
I took that and thought. RaspBMC is on a bit of a locally or over the network. While optimisation over the last few years has helped. Now you available here: Go to Browse and choose your network protocol to browse the network or alternatively.
If not. This might take a few seconds. It really is straightforward. For caravan and motorbike to higher ground. We suggest copying the following essentials into Notepad so they don't get lost: API key.
Sending tweets 03 Enable reading and writing Since you want to be able to send tweets. Twitter account name. These days you need to register an application with your Twitter account — you do have one. Building it might give you just enough warning to 02 Set it all up With your Twitter username and password.
API secret. Access Sending a tweet used to be really easy.
In your main Twitter account. If you did this before Step 2.
To build this with a conventional Arduino or clone. We are. As a bonus addition. Double-click the LX Terminal and type the following into the black window: Type in a shell window the following: For more information or to check out the documentation. Not to worry. Serial 'COM3'. Raspbian operating system.
The Bigtrak is a toy that takes in a list of straightforward commands Go forwards. The ones for the switch and power should be cut close to the PCB so we can reuse them later whereas the ones to the LED and speaker can be cut wherever you like.
Everything required on the software side comes pre- installed on the latest Raspbian OS images. This can be quite tricky as there is limited space to get extra hands in to help out. These are mostly easy to get at. The lid is connected to the base with a ribbon cable and a switch. It can help to wedge some thin plastic items eg a guitar pick into the sides to keep those two tabs unlocked.
This grille is held in place by four plastic tabs that need to be pushed in while at the same time sliding the grille away from the Bigtrak. With the lid lifted up onto one edge. In fact. With the switch and ribbon cable disconnected. GPIO modules. Carefully turn the Bigtrak back over and lift it up until the engine slips free. To know when the motors are enabled and reduce the chance of unexpected movement. This keeps the higher voltage the motors require away from the sensitive GPIO pins.
Having installed all of the wires. The connections made on the breadboard are listed in the table below. With the breadboard installed sticking it into place for support we can now. The wires will need to be long enough to reach the back of the Bigtrak. This type of battery is typically sold as a portable mobile phone or iPad charger — the one used here is rated at mAh. Step 10 09 Wire it all together In order to easily connect the motors and batteries to the breadboard we have soldered some modular connector plugs to the ends of the cable.
These values will be needed when writing the software and may be different depending on the breakout board you are using. With the PCB removed we can now attach wires to the motors in order to Bigtrak. The wires to the batteries can also be brought back to the same place to help keep things tidy. For setting up the software it may be easier to connect up a keyboard and Step 12 monitor to the Raspberry Pi at this point.
Possible next steps could be: Moving the left stick will control the left motor and moving the right stick will control the right. Connect the ribbon and power cable to the Raspberry Pi. Make sure that the red edge of the ribbon cable correctly matches up with the connector on the breadboard to save yourself from having to twist the cable inside the case.
If the analogue sticks are not controlling the Bigtrak as expected. As for the battery pack. As the script accesses the GPIO pins. We also have a Li-Po Adam Mickiewicz Have you got any further plans for that used selective laser sintering.
When working on it I found So what makes up the PiPanther — gaming tank. He loves to work on PiPanther. To be honest. Plus the biggest problem is the casing — turret. So battery at the bottom of the chassis. My Currently the chassis consists of four fast vehicle that you control using colleague and I the electronics guy elements. The PiPanther robot is a smart. PiPanther Battle your friends in augmented reality Tell me more about your hackable more work.
So you interface. The steering handled by the Raspberry Pi? I put a custom Ubotia robot. You can also make game elements like a landmine: Raspberry Pi The motors and if you want to turn then which is responsible for talking to the drive around in the dark wherever you Complete Manual you just regulate power between PiPanther mainboard using the serial want — under your bed.
I made that at a time and using the API you can control plugin and see a charger. That software is written in to throw other tanks. You can create. If you want to The Pi runs Arch Linux and on that an LED torch to replace one of the Raspberry Pi- gun attachments and you can then powered cars inside go forward then you power the two we have our PiPanther software. To drive a tank. We achieved a standard gun plugin. So if you have plugins then Like it? Keep have too much time because I have plugins could affect Ubotia gameplay an eye on the main PiPanther page for This mainboard is going to be available a small child.
He was work with Screenly. HDMIPi and Screenly and turn them into a beautiful digital photo frame Digital signage is a huge market in modern times. Screenly is an exciting piece of software in your Raspberry Pi collection. In this tutorial. On Windows you should use from RasPi. A community. Visit bit. Plug it in and wait for it to boot into the Screenly splash thought they were screen.
It is not hard to assemble. This is typically the easiest wired network is also required for the initial setup and for 2. Visit www. This is only a 3. Take a look at the image at the top of this the Raspberry Pi at your disposal or a spare Raspberry Pi and SD card reader page to see where the slots are in relation to the casing.
An IP address of format http: They would recommend a minimum of 8GB. This is completely free over SSH using the same IP address as shown previously iface eth0 inet dhcp for a single display on the splash screen. Once inside the dashboard. In order to do this you need to edit the ecosystem.
You can run the following command: The Screenly OSE dashboard should now load. We would also recommend changing the default password to something other than raspberry to stop any would-be hackers from easily accessing In this tutorial we the Raspberry Pi via SSH option 2. If your screen Screenly has black borders around the edge you may also need to disable Pro Edition overscan option 8 and then A1.
Screenly OSE. Once complete. Once you have got Screenly all set up and loaded all of your favourite pictures and videos onto it via the web interface. Plug in your speaker — we on top of Raspbian OS. If the Wi-Fi connection has worked. You need to select the keys on your Pi.
Repeat this step for each of the pictures. You could use this port forwarding on your router for ports 22 and Screenly from afar 15 Test with video and more Pictures are great. This is perfect if you want to enhance your digital some additional photo frame even further or perhaps display the local weather software running and news to keep yourself informed. Mould the spider dashboard. The Screenly image or grabbing it from a URL using the corresponding tabs. Whatever you make.
Select Image from the drop- down box and you then have the option of either uploading the 17 Other project ideas In this tutorial we have looked at just one fairly basic application of Screenly and the HDMIPi. The Ruiz brothers at a inch screen a few feet away eight-piece. But now it you split up the original video glasses? We have reading makes so much sense to give them away Noe So I guess for starters we bust out a really cool remote team that does To see some of the the calipers and we start measuring different projects as well.
Build more libraries for Learning System: So we prototype the piss out products for several different industries that. You just plug into a on a wide range of capturing the really good stuff and a few people have made their own and battery bank. But you together — the design and videography Adafruit site: When we started even better.
And quite to make it mobile. Pedro Ruiz will that print? We really strive to make our belt buckle with Adafruit LEDs and the guts out. We said sure. Adafruit liked Google Glass. From a design standpoint works and we make sure we keep the project and it gained momentum from it was really challenging because the pipeline full — sort of like a TV schedule. And that led to starting another more DIY. From there we designed the just now starting to collaborate with 3D-printed gadgets some parts and then follow along with components.
At the time it was a on the shop and she said: So what exactly does your DIY Glass do? Using all the features and functions of the Pi. Pi-powered games console that you can play Minecraft on and learn how to program too Minecraft means many things to many people. Q Raspberry Pi case In this tutorial. Q Latest Raspbian image However. Not everyone knows. Launch the desktop. Open up Updates to the terminal and use: Pi Edition?
We recommend you install a fresh version of Raspbian. Pi Edition can chug a little on the original Model Bs. This is a it does come though. We can make it autostart by going update for a little while. Go to Enable Boot to Desktop turning it off by physically removing power. Above Give Minecraft: Pi Edition currently works on Raspbian. Pi Edition is quite limited in what it lets you do.
Now with more power. Make sure you get a 2A supply. There is a great list of compatible Wi-Fi adapters on the eLinux wiki: There are many networked computer using the following: It should only cost — the former will be underpowered and the latter is not always Minecraft and do a bit more with it to suit your needs. The only way to find the answer to these questions is with some sort of security system.
Note that you will need a high capacity microSD card, or a USB storage device, for storing footage from the device. This Raspberry Pi project combines the motion software with uvccapture, a tool for capturing the footage from your webcam. The ffmpeg software is also used to for managing the bitrate and time lapse. Email alerts can also be configured. What if they could do more than just display your favorite family photos?
Using this build, you can create a digital photo frame that delivers inspiring messages alongside photos of beautiful scenes from around the world. The result is something that dazzles your eyes while making you really think about the message. While we used a Raspberry Pi touchscreen display for this project, any LCD display that can be connected to the Pi should be suitable.
I've been trying to snap the stars and moon -- perhaps even the Aurora Borealis -- using my Raspberry Pi for months. Almost every time, it fails, or at best returns distinctly average photos and This gives you the opportunity to snap stars, meteors, the moon, planets, even UFOs.
For instance, you might use time-lapse photography to track the path of the stars and the moon overnight. Or employ a slow shutter speed to get a trace effect. Whatever your plan for night photography, the Raspberry Pi should suit your requirements perfectly.
