You can hook up the battery cable via terminal connections to the UPS. Be sure to push the black negative pole of the cable into the left connection jack that is labeled GND. Installation guidelines  with detailed illustrations in English can help during setup. Be aware that when a UPS board is added to the Raspberry Pi, it will no longer fit into all Raspberry Pi housings because of the increase in size. If you find that a particular housing is not large enough, you will need to work on it to create openings and notches as needed. Make sure you create an opening for the micro-USB connection, because the power supply for the Raspberry Pi comes via the added board. If you see orange, you should check the connection to the board or change out the batteries.
Wire a 12v fan to 5v Raspberry Pi GPIO pins?
Build This DIY Touchscreen Music Player for Your Car All you need is a Raspberry Pi and a dream May 9, Ryan Lowry Have you ever been stuck in traffic and pulled up next to some maniac singing along with the radio to an audience of no one, index fingers drumming out a spastic beat on the steering wheel? Advertisement – Continue Reading Below A few months ago I realized my haven was losing its appeal, and I sensed it was connected to my radio’s anachronistic scan button.
If you haven’t heard of Raspberry Pi yet, remember the name—this easy-to-use microcomputer is taking over the programming world. Lauded by amateurs for its accessibility and by experts for its versatility, the Pi has been the catalyst for all sorts of cool projects: Setting it up for this project was fairly straightforward. The Pi is basically a Swiss Army Knife of inputs that you’re already familiar with:
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.
My dream car would be a manual transmission Jeep Wrangler or a nice, fast sports car. But even in older model cars computers are very prevalent. For this reason, I have decided on a project that I will complete over Christmas break. My plan is to build a system using the Raspberry Pi that gives me a readout of all the car statistics. You may not know, but cars know a lot more information than they tell you on the dashboard.
Sure, they know your speed, engine rpm, amount of gas, etc. For example, the check engine light is a very general light, it could mean a lot of things; the car knows more specifically what the issue is, but has no way to tell the average driver. Besides the additional information, I could also turn the Raspberry Pi into the entertainment center, thereby making my own infotainment center. I will not pretend that I can do a better job than companies with thousands of dollars to throw into their research, but with a simple setup I believe I can give it the basic functionality I want, and make it work in a way that is more natural to me.
An issue I have with more modern cars is how similar they look, so making the Raspberry Pi my infotainment center would give my car a more personalized appearance which I can hopefully make professional looking. This entry was posted in Passion blog on.
Raspberry Pi Install
If you are willing to commit jumper wires to the project, cut and strip one end off of the wire and solder like below. The instructions below use a bit of hookup wire to avoid snipping apart jumper wires. Secure the red lead from the piezo element in your Third Hand clip and tin the exposed wire by heating the wire and coating it with solder Cut two inches of red hookup wire Strip both ends of the wire using your wire stripper Secure the red hookup wire in the other clamp of the Third Hand so it is overlapping the lead from the piezo element Solder the piezo element red lead to the red hookup wire.
Optionally, you could cover this joint with heat shrink wire Insert the other end of the red hookup wire into one end of the red jumper wire Repeat the steps above for the black lead, black hookup wire, and black jumper wire Cut a large circle from the plastic to make a vibrating membrane for the element.
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.
On your laptop Windows, Mac or Linux 1: Instructions to download and install it are here. Optional Install a VNC viewer. Download or clone the modified FormulaPi code from this Github repository Copy rover. It just listens for motor commands over Wifi and sends them to the motor controller board Race: This is the script that commands higher level racing tactics. Instructions and tips are here. It should show you live video from your rover.
Note that you will probably have to change the hard-coded IP address in the code to that of your RasPi, as descibed in the next section.

These devices may fall under your jurisdiction as a desktop administrator, so get familiar with these technologies now to prepare yourself.
Raspberry Pi in my Ford Focus running Raspbian Wheezy. I have always loved those old TV series with futuristic tech in those futuristic vehicles, like Knight Rider, Airwolf, and Street Hawk. So it got me thinking about how easy it would be to add a computer to a vehicle.
Which is probably not much good for a security camera. You can find the normal camera here or the non-IR camera here. Now the connector is open insert the ribbon cable with the metal leads facing away from the Ethernet port. Make sure it is nicely line up and then gently press back down on the connector. The cable should now be locked in place and we can now move onto the software.
On a side note if you want to install this into a more secure enclosure there is some great equipment you can buy or even design to do this. To keep this tutorial pretty basic I am not going to go into a heavily customized camera enclosure. You will need a formatting tool. Follow the instructions to install the formatting software. Now unzip the MotionPie img file so you can install it onto the Pi safely.
Raspberry Eye In The Sky
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:
REQUIRED FOR PI: Raspberry Pi 3. If you’re reading this, I assume you know what this is:) Definitely want to buy a Pi 3 for the onboard Bluetooth if you want to do any bluetooth stuff.
Our interest in this feature and in driving technology led us to our desire in developing an inexpensive, Raspberry Pi-based dashcam with a lane departure warning system. Lane departure is the leading cause of fatal crashes; inexpensive, widely-available lane departure warning systems could save many lives. Introduction Our project involved integrating 3 separate components together: The first component was a dashcam that could record video and save it to a removeable drive for future viewing.
The second component was a lane departure warning system that could detect when a vehicle was drifting out of its lane and warn the driver. The third component was an accelerometer that could provide additional data that could be stamped onto the dashcam video, such as the cardinal direction of the vehicle, and the G-forces experienced by the vehicle.
The accelerometer detected the direction and G-forces of the vehicle and sent it to the Raspberry Pi, which stamped the data onto each frame of video before saving it to an external drive, such as a flash drive. At the same time, the Raspberry Pi analyzed each frame of video in real time to determine whether the vehicle was drifting from its lane. If a partial drift was detected, a yellow LED would light up. If a major drift was detected, a red LED would light up.
Also, if the G-forces exceeded a certain threshold, a blue LED would flash for a few seconds. We chose this camera because it was easy to hook up to the Raspberry Pi, had native support, great resolution and was well supported with a lot of online resources. We started by setting up the pi parameters and taking test shots at different resolutions and modes.
We then did this while implementing multiprocessing so the pi could use all 4 cores.
Raspberry Pi – Driving a Relay using GPIO
Controlling a toy car with Evothings Studio, Raspberry Pi and your mobile device. Check out the video below, and if you are interested in how we managed to do this within a couple of hours — keep reading. You are also very welcome to talk with us about these kinds of projects or application development in our forums. The car was originally controlled with a radio remote control and the goal was to instead use our mobile devices. We decided to use the socket.
Evothings Studio enabled us to instantly start developing and testing our application.
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.
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. The most important to our circuit is the coil rating, which is the current at a specified voltage required to energise the coil activate the switch , sometimes expressed as milliwatts mW. The AC and DC load ratings relate to the switch-contacts, and state the maximum load current e.
DC loads are rated lower because they arc spark more, which eventually wears the contacts to the point of failure. In general, large loads need heavier contacts, which in turn need bigger coils to switch them, and bigger coils need more power from your circuit. The choice of GPIO 17 was simply because I considered it less likely to conflict with other peripherals likely to be in use. Although the pin is marked 3.
