This has — apart from the price — a few advantages, which will be discussed in more detail below. A plug adapter makes connecting the power cable to the power supply very easy. This includes the following in addition to a Raspberry Pi :. The maximum power of the power supply depends on the number of LEDs. So, a power supply, which has up to 10A is suitable. If you have more LEDs in use, you may need more than one power supply more on that later.
These are available in three different versions, which differ in the number of LEDs per meter:. The length should be chosen depending on the project to be implemented. But mostly 5m rolls are a bit cheaper. These have a higher density of lights and thus a higher brightness. In terms of price, however, they are still cheaper than a similarly long WS strip with only 32 LEDs. With only one data line, the frequency must be higher to carry the same amount of data.
The answer is quite simple: the cheaper price. In comparison, one meter of WS is quite expensive, which is why you want to handle it more sparingly. At relatively low prices for several feet of a WS strip, even a large projects can be realized without a huge budget.
However, it must be said that it is unfortunately not possible to simultaneously play sounds via the Raspberry Pi onboard sound card and control the strip. Using both at the same time is not possible, which is why someone who relies on the sound reproduction should just take the WS If your strip has less than LEDs, external power is not required.
If it has more LEDs, the power of the Pi, however, is no longer enough and an external power supply is required. The power supply itself depends on the selected type. For a power adapter with additional DC adapter beginnersonly the DC adapter needs to be connected, which will be followed by the power cables of the WSB.
Once you have chosen this method, you can jump to the next point. A switched-mode power supply for experienced usershowever, is a little more complex. Before, however, the note: When working with V caution is necessary because of mortal danger! Get help from an electrician or get back to the safe version of the normal power supply!
Perform all work with a separate network connection. First, we need a standard power cable that can handle 10A. Mostly on the bottom of the plug is a corresponding note V, 10A.Neon mouse pointer
We cut this cable carefully with a utility knife or similar. It contains two or three cables with different colors. These cables must also be carefully stripped. For connection to the switching power supply, the colors of the inner cables serve as orientation. After the locking screws have been tightened, the power cord can be plugged into the socket and the voltage at the power supply can be measured with a multimeter.
Although this is not mandatory, but can be made as a hedge.AstroPiBox is available for sale on the Clef des Etoiles web site. Here are some news about the AstroPiBox Advanced version. We have performed many tests on various equipments and components in order to achieve our goals in terms of functionalities and reliability.
To assemble all these components, a motherboard is required. We have luanched the design and production of the AstroPiBox Advanced motherboard, which has turned into a process more complex than what we anticipated. Here is an extract of the 5th version of motherboard:.
We are now finalizing the motherboard and 48 hours of test have already been conducted. The last task is to design and produce a box that will be manufactured with a 3D printer using "ASA" plastic. The box must be designed specifically to accomodate dew, which makes the process more complex. As a conclusion, the project is progressing but not as fast as we expected initially.
So the suscribers to the crowd-funding project will have to wait a few more months to get their AstroPiBox advanced, but we think it is worth it! AstroPiBox is a portable platform dedicated to astrophotography. Its first objective is to provide the amateur astronomer with a reliable, easy to use and high quality autoguiding service.
AstroPiBox also integrates several other software products and utilities to facilitate mobile astronomy : planetarium software with telescope control, image acquisition, astrometry resolution and light pollution simulation. It must be noted that these additional functions are still experiemntal and will evolve over time knowing that the main objective of the AstroPiBox is to deliver an autoguiding service.
PHD2 represents the reference in the arena of autoguiding solutions for the amateur astronomer. All the required libraries have been pre-installed in the AstroPiBox Linux environment so that the PHD2 software can be directly and simply launched then used.
The French translation has also been greatly improved. Note that code changes made in PHD2 will be delivered back to the open source community in order to comply with the initial open source orientation of the software.
This makes the solution very easy to use while continuing to benefit from the powerful features and algorithms which are provided by this software. It is of course always possible to adjust the numerous parameters proposed by PHD2 in order to refine the autoguiding results of a specific configuration.
AstroPiBox has been tested for autoguiding with the following equipment either through a direct connection or through an ST4 port :. For these cameras, it is therefore not necessary to go through the INDI Library interface even if this stays possible.
CCDciel constitutes a simple and efficient tool to perform image acquisitions from a camera connected to the Raspberry Pi. AstroPiBox also embeds the well-known astrometry resolution engine Astrometry. The user just has to specify the image to be solved into the GUI as well as the sampling associated to the setup that took the image in order to obtain the result of the astrometry resolution in a matter of seconds.
There is no need to specify an approximated image center to perform the image solving. AstroPiBox is delivered with an innovative tool to simulate the light pollution produced by public lighting. This greatly helps in the process of identifying the best spots to practice astronomy.
All what the user has to do is to specify a town name, its area code as well as a latitude extension for the map in km and AstroPiBox immediately generates a light pollution map centered on the requested town. At this point of time, only France cities can be simulated. In its version with a 7" screen AstroPiBox TouchscreenAstroPiBox lets the user easily change the screen luminosity through 5 dedicated buttons.
Furthermore, a night vision is available to switch the interface display to red tones. Raspberry Pi 3 with a standard case and a power supply.
Use case: integration within a permanent observatory. Final product with a watertight case designed for astronomy that integrates a power management system, a USB 2 hub, a serial port and proper connectors for a usage in the field.
Here is an extract of the 5th version of motherboard: We are now finalizing the motherboard and 48 hours of test have already been conducted. Light Pollution Simulation AstroPiBox is delivered with an innovative tool to simulate the light pollution produced by public lighting.Our mission is to put the power of computing and digital making into the hands of people all over the world.

This way the Raspberry can act as a DMX server, while any system can send packets to it.
The Pi is running Raspian 3. Once all 5 elements have been configured, you should have this on the left hand side of the screen. Now we need to set up the controller and link the lights to channels on the controller.
We can name our controller anything.Raspberry Pi: Automated lighting control using 8 channel relay and PIR motion
You need to patch L1 to 1, 2 and 3 and L2 to 4, 5 and 6, etc…. We need to configure the controller for Universe, where it starts and how big it is. This is a two-step process. First, right click on the destination dropdown, a box asking for the IP will immediately appear. Next, select the Unicast option from the Destination dropdown. Which will now be populated. One is probably the best default. If you set it to something else, then use the —universe option on the DMX utility to ensure that both ends match.

Thread Tools Show Printable Version. I need it to be a timed sequence of lights to a mp3 file. In other words, it no longer works. I have what I think is a timed sequence of lights in Vixen 3. My questions are: How do I get an output file from Vixen 3? TIM file, and no other option to export the file. The tutorial is incomplete. How do I get the music to play on the Raspberry Pi?
The omxplayer file is no longer included on the OLA image. I know there's an update for Vixen that includes a Raspberry Pi player supposedly sometime in the middle of this year: Vixen Roadmap Unfortunately, I can't wait that long. I need to have something put together by mid May. Is there anyone that can help me, in terms of a starting point or documentation? Am I using the right software? At this point I'm very lost, and anything would be appreciated.
Thanks Graham Best. Attached Files Test. And install FPP on your pi, convert your mp3 to ogg file. And your ready to run your bridge. Graham Best thanked for this post.
