Games and emulation quality The latest version of the Raspberry Pi is great. It offers up to six times the power of the first-gen model, yet doesn’t cost any more or take up extra space. Step back a minute and you realise it’s only about as powerful as a budget phone like the Motorola Moto G. But that’s plenty to give you enough scope to do some amazing things. The Raspberry Pi makes a fantastic retro gaming console thanks to the efforts of the bustling indie dev scene that surrounds the computer and its predecessors. Read on to find out how to do this yourself. Check out our list of Raspberry Pi projects Downloading the right software We’re going to make this as simple as possible, so we’ll be using a piece of software that boots straight into the emulator interface. This can be dumped right onto the Raspberry Pi’s microSD memory card, meaning you don’t need to do any fiddling about with Linux, Raspbian or anything else.
For instance I had a USB keyboard but this died. Similarly, I gave my old USB mouse away, so had to pick up a new one. I also used a microSD card with an SD card adaptor to start off with, resorting to the full card when I decided to find something more resilient and robust for storage. Other Hardware You Might Need The collection of hardware above should be all you need for basic use of your Raspberry Pi — ideal for using the device as a means for learning how to program after all, that was the original idea…!
However as time progresses and you decide to start trying a few projects, you might just find that you need to start adding a few more pieces of hardware into the mix. So, how much have I spent on my Raspberry Pi so far?
With Raspberry Pi, we can make your car Tesla-like and integrate it into a real carputer. With a Raspberry Pi car touch screen, your ordinary car is opened up with vast possibilities and opportunities.
In those days, things were far simpler. Instead of paying extra for a monitor, the Read More , you might have opted to purchase a Raspberry Pi touchscreen display. Here’s how to set one up. Read More , the touchscreen display has so many possibilities. The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card.
You’ll need a battery of some sort — but there are several options available. Several options are available to create a Raspberry Pi photo frame, mostly using Python code. You might opt to script your own, pulling images from a pre-populated directory. Alternatively, take a look at our guide to making your own photo frame with beautiful images and inspiring quotes ShowerThoughts and EarthPorn: The results are always impressive!
The Next Generation to your Raspberry Pi today? Raspberry Pi Carputer Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display — and what better than a touchscreen interface?
Also, many users prefer a convenient switch to clicking icons and entering shutdown commands. We show you some options for starting, stopping, and powering down. Over the last year and a bit that the Raspberry Pi has been out in the wild, users have discovered that this little computer can do almost anything — and without crippling your wallet! However, Raspberry Pi’s very small price tag and form factor mean that the Rasp Pi has had to do without some of the home comforts normally found on a laptop or desktop computer — one of these comforts is a power-on and -off switch.
The only safe way to shut down the Raspberry Pi is to do it manually using the graphical desktop interface — either with the LXDE power management window or by opening a terminal window and typing in a shutdown or reset command. Although an orderly shutdown is not a huge amount of work, it often gets overlooked or forgotten, and some users just pull out the microUSB power plug while the system is running.
Raspberry Pi Touch Screen Car Compute This is a detailed project on instructables which explains how to run a media center on the Raspberry Pi and connect .
Various odds and ends mentioned within the Instructable. Add Tip Step 1: Gather Your Materials for Assembly No, this isn’t real programming Here is what I used: Assemble the Screen This is fairly simple but there is still room for error. They are both labeled in the previous step. Then, plug the ribbon cable from the screen into the control board with the same orientation as pictured.
Some randomness from Gavin Cameron Raspberry Pi s I’ve been following the Raspberry Pi project since before they were released to the public and should have been one of the first in line to get one! I was waiting in my car at The network was slow and the websites were overloaded Anyway, the first one arrived many weeks later and I played with it. Eventually, a 2nd revision board was announced, so I simply had to order one.
The Raspberry Pi is stored in the centre console and all wires routed underneath. Audio is fed through the aux socket of the car’s radio so no additional hardware is needed for this.
After many requests stemming from my desktop Pi power switch, I have created a power supply for the Raspberry Pi which senses your car’s ignition. A microcontroller handles all logic operations like the desktop switch. The power supply maintains power until the Pi has safely finished the boot-down process and then removes power. The supply is most easily installed by connecting to 3 wires behind your radio: This is useful if you make frequent stops and don’t want to wait for the Pi to boot every time you restart your car.
The power supply will also automatically remove power after 4 hours of the ignition being off to prevent a stalled Pi from draining your car battery. I will be providing two versions – a 2amp power supply and a 3amp power supply each with the option of single or dual USB ports on board. The USB ports are power only, no data. This is useful if you have your Pi mounted in a hidden location or enclosure.
The power supply has a built in resettable fuse for protection. Risks and challenges The biggest challenge will most likely be for non-auto savvy users to wire the power supply into their car. If the user has any experience with installing a car radio then this will be no problem. I will do my best for other users to provide basic installation diagrams and instructions.
Add and stream content You can use the Raspberry Pi to do all kinds of geeky things but one of the most interesting uses for the little device is that of a home theatre PC or HTPC. The small size of the hardware and the fact that it runs silently make it a really good choice for building your own entertainment centre. One of the best open source apps for turning any computer into a fully functional media centre PC is the recently rechristened Kodi media player , formerly known as XBMC.
Kodi uses a foot user interface, which is ideal for connecting to large-screen displays and projectors. The interface has ergonomic display elements and can be easily navigated using a remote control. You can also control playback using your Android smartphone.
Perfect for hooking up to the Raspberry Pi’s video output. Most of these screens are sold as car reversing camera screens, are powered from 12V and often have two video inputs available. The one I’ve got was £16 on eBay and I wrote about it in my Cheap Miniature LCD Screen article.
How do I power my Raspberry Pi? The least complicated, but most stringent in terms of power requirement is the Raspberry Pi! The latest version of the Pi 2 can be powered effectively in a couple of ways. The recommended input voltage is 5V, and the recommended input current is 2A. The reason for increasing the voltage slightly is to negate any voltage drop caused by excessive current draw.
This is well within tolerance for Micro-USB, and from experience, we have found that this give the best stability for most applications. The Raspberry Pi can function on lower current power supplies e. This is demonstrated below: It should be noted that, unlike the Micro-USB port, there is no regulation or fuse protection on the GPIO to protect from over-voltage or current spikes. If an incorrect voltage is applied, or a current spike occurs on the line you can permanently damage your Raspberry Pi.
To power via GPIO, you only need to connect 2 pins: Connect a 5V source to Pin 2 5V 2. Connect the ground of that source to Pin 6 GND.
Raspberry Pi has as little to do with raspberry pie as it does with giving someone a raspberry you know, the kind you used to give people on the playground back in the day. It has been developed with the intention of promoting more computer science classes in schools, and the low price point makes it easier for schools to adopt. You will be, too! This instrument lets people play drum beats by touching actual beets, powered by Raspberry Pi. Click here to see a full video of how it works.

Raspberry Pi users seem to like Anker external batteries. Connect the battery to the Pi with a micro USB cord. Connect the touchscreen with a USB-to–barrel plug.
Now mount the Raspberry Pi to the standoffs. Plug in the RPI-Display cable: And, wire the GPIO as follows: If you have a good power supply, you can just put the power into the outlet on the display board, and it will power both the Pi and the screen. Alternatively, you can power both independently if needed. You will need to install some software to get it running: My Thoughts Honestly, I was a bit skeptical when ordering this thing. I was pleasantly surprised right away.
Here are some of the features I noticed: It does not feel like a cheap or flimsy screen. You can actually use it for stuff.
The aim was to send images from higher than my record of just under 40km, so the tracker was pretty much as light as I could make it. For that I made a more suitable payload box, keeping the original for a later date. That was a great flight with, as far as I know, the only live images sent from a flight of that type. It was also the first flight to use the new Raspberry Pi camera, and it got some good images though overall the success rate was much lower than I hoped for. Last but not least was to get the latest Pi camera software and configure it to use matrix metering mode.
I also changed the code a little to take 3 types of image each about once per minute:
With this tutorial you will be able to make your own car-pc by using the Raspberry Pi 2. All credits for this Car PC System goes to Andrei Istodorescu (official link), I only made a more detailed “how to tutorial” following guide is only for the Raspberry Pi 2 Model B board!
Still in NC Certainly some interesting ideas. There’s a guy mausberry circuits?? Auto-shuts-down the unit once power is cut. I’d like to make a “low voltage” auto-off for mine. Electrically, motorcycles are very noisy Replace your turn signal relay with it to give yourself programmable turn signals. You could have them turn off automatically based on distance from when you turned them on via your GPS.
You could also make them ‘do’ interesting things If you have like a heated seat or heated clothing, you could use it as a thermostat based on current temp. Fancy version would consider windchill Turns up your vest when you are going highway speed on a cold day, turns it down when you get back into stop-and-go traffic. Telemetry data keyed to significant events on your bike Use it as a sort of roving NAS that downloads movies from your local storage when you are connected to your home wifi but then makes them available as a wifi AP when you are roving in places with no connectivity.
Anyone at camp who wants it can just wifi connect to your bike and stream movies or audio.
How to build extraordinary projects with your Raspberry Pi This learning bundle helps you discover the Internet of Things and robotics. By Stack Commerce posted Aug 23rd, at This bundle takes you from initial setup through to exciting weekend projects. Stack Commerce Owning a Raspberry Pi allows you to explore cutting-edge technology on a manageable scale.
Since Raspberry Pi only has HDMI and composite video outputs, the display needs to be switched to composite input. Steering wheel controls There are 6 buttons on steering wheel for control of navigation system- Back, Enter and 4 directional keys (up/down/left/right).
Although a simple project, I still learned some new things about the Raspberry Pi while doing it. There are only four components required, and the cost for these is around 70p, so it would be a good candidate for a classroom exercise. A word of caution: A mechanical relay allows a safe learning environment, since you can switch any load with it e. A more efficient alternative to switch an AC load would be to use a solid-state relay e.
The Circuit There are four components to this circuit.
January 22, The ability to inexpensively but accurately measure distance between an autonomous vehicle or robot and nearby objects is a challenging problem for hackers. Knowing the distance is key to obstacle avoidance. Running into something with a small robot may be a trivial problem but could be deadly with a big one like an autonomous vehicle. I used a web camera for vision processing and attempted various visual techniques for making measurements, without a lot of success.
At the competition, two entrants used scanning lidars which piqued my interest in them. A lidar is a laser range measurement device.
Benjamin set the Raspberry Pi up as a web server, enabling it as a wireless hotspot. This allows the tablet to connect wirelessly, displaying roadmaps and the media centre on his carputer dashboard, and accessing his music library via a USB flashdrive.
The steps in this article are very close to the correct working steps, though there are a number of things you must check. In our use case we started with the Raspbian Jessie Lite Image found here: I did a number of things to make it more accessible for me: So I was working from a very minimal image with very little changes. I then performed the following steps: The version of PulseAudio in the default raspbian repo is 5.
That last apt-get is going to install pulseaudio 5. When you build pulseaudio from source and install it, its going to install into: Now we need to make some config changes. The version we installed from source is going to look at: Save and exit daemon. I currently have the following command issued upon boot via init. You can try it out and see if its not needed, I plan to do so soon.
After reboot we need to make sure that ofonod and pulseaudio are both running.
