How to make arched tracks?

Hi,
I'm building Led boards for power leds mounted on a circular board.
To go from one led's connection (series connection) to another one, I'd like to use circular (arched) tracks...
using the normal 0° / 45° / 90° tracks looks quite messy, and makes me loose valuable cooling space..
Does anyone know a good ad simple trick to do so?
Best regards
Johan

Hi Johan,
I don't know of a way to make perfect spirals in Ultiboard, but you can use the arc tool. The arc tool continues drawing from the end point of the last arc if you don't leave arc drawing mode. This makes it easy to make spirals by attaching cirular arcs of increasing diameter. I suggest the following:
Figure out the width and pitch of the spiral you are drawing
Set the grid to cartesian with grid size of the pitch of your spiral
Activate the copper layer to place the spiral on
Select the arc tool
Change the copper width to the width of your spiral
Start placing copper, each end point of each arc should be directly opposite to the previous point
I am afraid I may not be very clear. Here's an attachment that shows what I mean. It should work in Ultiboard 10.1.1.
Hope that helps.

Hey Pancenter there are still lots of us about.
I wouldn't take the original post too seriously - I may of course be naive but it sounds like it could be a troll to me!
I learn a lot from reading the posts of the likes of you, Erik, Bee Jay, sampleconstruct, noeqplease etc so I hope you guys don't become too dispondent when you see posts like these.
By the same token, I hope the Logic team continue to use their talents to develop powerful software that caters for the professional user, while allowing Garageband to continue to do its (excellent) job of providing for its market.

How to make timecode track in transcoded file match original

Using Compressor 4.1.3, when I make an H264 QT from a DNX36 QT, the timecode track does not replicate properly. The first frame of timecode repeats for a frame which makes every frame after that read as one frame earlier than it is in the original file.
For example, the first frame of the original file is 01:00:00:00. In the H264, the 1st and 2nd frames are 01:00:00:00, and the 3rd frame is 01:00:00:01. The 3rd frame should be 01:00:00:02.
The DNX36 is a QT Reference movie exported from Avid MC 7.0.4.1. I am reading the timecode on the QuickTimes using QuickTime Player 7.6.6. This works correctly with Mac OS 10.7.5 and Compressor 3.5.3.
The system I'm having the trouble on is Mac OS 10.9.4, Compressor 4.1.3
Any ideas on how to make the timecode track of the transcoded file match the original?
Thanks.

I'm not sure what you are getting at. Is a string child the contents of a node treated as text?
If you are trying to match a child node regardless of case I doubt this is possible as the XML standard says an XML document is case sensitive so if your parser ignored case it would not be XML complient.
Hope this helps.

How to make Different Tracks in a Recording

HI there ...
I'm just starting to make my way around GarageBand ...
I have to do a recording tomorrow ... its an audition for a pianist. He's going to have to play some solos, scales etc ... all told it will be about an hour and a half of recording or more ...
What I need to know is ..... Every part of the audition has to end up as a different track on the cd I make of it. For example the ten scales has to play would each be a track number ... his solo piece another number and so on.
How do I mark tracks on the recording? Also ... if I set up the recording and just press record every time he plays ..... am I going to have enough space in the one project to record everything? I thought I read somewhere that garageband has a limit on the number of bars that it can record.
Thanks so much for any help .......

I just looked at Amadeus Pro on the web .... Does it do recording too?
Yes
How many tracks can it do ....
I don't think it's actually specified, but lots. (Actually I don't think this is what you are talkin aboujt, it can do numerous simultaneous tracks for mixing down: but yes, you can split a single recording into separate ones.)
If I record on GarageBand ... can I use Amadeus to
edit the GarageBand file? ...
Yes - first export to iTunes then drag the file from iTunes to the desktop and then drag that to the Amadeus Pro icon in the dock.
.... Cut sections out ... Mark tracks .... and burn a
CD? ....
Yes, yes and yes. The program is still in beta and I haven't actually tried the CD burning facility, but in any case you can burn audio CDs from iTunes.

How to make arch bootable after shifting the hard drive?

I have two hard drives, each having an OS installed (Arch on sda, Win on sdb). I change the boot order in BIOS to switch between the OS's, and it works fine. Grub is installed in mbr.
But now I wanna change the connection of these two drives (Arch=>sdb, Win=>sda). After doing that, however, windows is still bootable, while Arch not any more.
I can sucessfully see Grub, but errors occur after that. I'm not sure what I should do to make Arch bootable. Can anyone give me some ideas?

If you can see Grub, then the system is reading it OK, but you'll need to boot the system and fix your /boot/grub/menu.lst and /etc/fstab files to refer to hd(1) and sdb respectively.
To boot the system, you have 2 options:
1) When Grub shows up, press 'e' to edit the "ArchLinux" entry. Then press 'e' again to edit the 'root' line and then change hd(0,0) to hd(1,0) (the second number might be different depending how your partition table is setup). Then you can press 'b' to boot.
2) Use an install CD to boot, then mount your Arch partition and edit the files from there

How to make audio track respond to timeline

I'm starting a project and need the ability to control the speed of an audio file playback using the timeline.
There are specific events that happen at certain times in the song, and i need the ability to scrub forward and backward on the timeline, including the audio. is this possible?
I have a mechanism to scrub through the timeline of a symbol, but i can't get it to recognize the audio track.
I use this code on the stage in a "composition ready"
var symDur = sym.getSymbol("timelinePlay").getDuration(); // Get the timeline length of timelinePlay. We'll reference this later in the code. var mySymbol = sym.getSymbol("timelinePlay"); // Get the symbol timelinePlay. We'll reference this later in the code. var scrubber = sym.$("scrubber"); // Touch this to scrub the timeline of timelinePlay var bar = sym.$("bar"); // Bar the scrubber follows sym.$("mobileHit").hide(); // Added an extra invisible div to increase the hit region for mobile (hard to grab otherwise) var dragme = false; // Set the initial dragme function to false // Detect if mobile device, and if so swap out mouse events for touch events. This is pretty much duplicated code with touch events swapped. if (/Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)) { sym.$("mobileHit").show(); // Show the extra invisible div to increase the hit region for mobile (hard to grab otherwise) $(function () { scrubber.bind("touchstart", function (e) { // Enable the scrubber on touchstart e.preventDefault(); // Cancels the default action of the mobile device - used to ensure our touch events are fired dragme = true; }); scrubber.bind("touchend", function () { // Disable the scrubber on touchend e.preventDefault(); dragme = false; }); scrubber.bind("touchmove", function (e) { // Make the magic happen on touchmove if (dragme) { var touch = e.originalEvent.touches[0]; var possibleX = touch.pageX; var leftX = bar.offset().left; var rightX = (leftX + bar.width()) - scrubber.width(); var scrubWidth = rightX - leftX; // Confine the scrubber to the width of the bar if (possibleX < leftX) { possibleX = leftX; } if (possibleX > rightX) { possibleX = rightX; } scrubber.offset({ left: possibleX }); var relativeX = possibleX - leftX; var stopTimeline = Math.ceil((relativeX / scrubWidth) * symDur); // Make the scrubber scrub the timeline length of timelinePlay mySymbol.stop(stopTimeline); // Stop the timeline of timelinePlay when the scrubber is released } }); }) } else $(function () { scrubber.mousedown(function () { // Enable the scrubber on mousedown dragme = true }) $(document).mouseup(function () { // Disable the scrubber on mouseup dragme = false }) $(document).mousemove(function (e) { // Make the magic happen on mousemove if (dragme) { var possibleX = e.pageX; var leftX = bar.offset().left; var rightX = (leftX + bar.width()) - scrubber.width(); var scrubWidth = rightX - leftX; // Confine the scrubber to the width of the bar if (possibleX < leftX) { possibleX = leftX; } if (possibleX > rightX) { possibleX = rightX; } scrubber.offset({ left: possibleX }); var relativeX = possibleX - leftX; var stopTimeline = Math.ceil((relativeX / scrubWidth) * symDur); // Make the scrubber scrub the timeline length of timelinePlay mySymbol.stop(stopTimeline); // Stop the timeline of timelinePlay when the scrubber is released } }) })
and have an group called 'scrubber' that contains a div called 'dot' and a box called 'mobileHit.' There's a horizontal bar that's not included in the 'scrubber' div (representation of a timeline) called 'bar' on top of which the 'scrubber' sits.
the whole contraption controls a symbol called "timelinePlay"
If there's any way to get the audio included in the timeline and give me the ability to scrub through the timeline /and/ audio, (imagine manually fast forwarding and rewinding a VHS tape) that would be wonderful!!!

anybody?

How to make various tracks distinctly visible in fcpx ?

I have to remember what material I have put in which track.....Is there a way to create a visual difference by color or name or something that in you multi track project you can just know that in this layer are the NG takes....or in this are the safety shots or something like that....it visually becomes confusing when project becomes big.Or like one compound clips is lying in which are all the 'might be used' shots.....can I label it in someway that I can recognize the clip among hundreds of them.....??

Custom Roles (and Sub-Roles) -- I know it sounds like a pain in the you-know-where... but it can be a timesaver if you have the discipline to set them up.
When you select the role/subrole you're working on, the clips "light up" and are easily distinguishable from all other clips on the storyline.
Below I have "old edit" highlighted (and the "new edit" clip thumbnails are minimized [see the small icon on the right side of the column is selected:])
And below the "new edit" role is selected lighting up the clip on the storyline.
You can command click multiple roles/subroles to highlight different wider-scoped aspects of your project.
You can also change Roles for clips once their status has changed. There are a variety of ways to do this, but one of the easiest is to customize the timeline index a little first. If you go to the Clips tab and right click on the column title bar, you can set what is shown:
I have Position and Roles showing (I don't use notes ordinarily nor the Active Angle as I don't do a lot of multicam.) From this pane, you can shift or command click any number of clips in your storyline then go to any one of the downward turned triangles in the Roles column and change the assigned role for all those clips simultaneously.
There's no way (yet) to set the colors of clips, but you can do a lot of very sophisticated organizational things with Roles.

How to make a Track matte on a text layer??

Hi,
I have two text layers stacked one above the other. The top layer scales up and blows up to reveal the text layer down. I have tried to use the Text Layer above to the down below but it disappears and does not show any effect. The same effect shows up when I have a simple image and a text above it, as I watched a couple of tutorials on various on line resources, but does not show anything if the layer beneath is alos a text layer created in after effects.
I know I am wrong somewhere.
Please help me sir.
Thanks,
Kangana

I'm sorry, but I realyl can't picture what you are describing. Please provide screenshots of your timeline and the result and tell us more about what's involved. Generalyl it doesn't matter how you create such matte effects - they work wit hal layer types - but you may be using a specific effect, layer style or otehr feature that breaks this functionality and may requirte pre-composing or otehr techniques to compensate.

How to make arch safe enough to remote desktop?

I have a dsl connection at home, and I need to remote from work to my home usually.
Sometimes I need to reboot my computer at home from a remote connection because I need to change to another OS.
The problem with arch, is that if adsl is not able to connect at startup for some reason, it wont try it later, and I will lost the machine.
Other distributions, like debian, keeps the daemon running until it connects, or try it later; I can do the same with windows and it dsl connection properties; but so far, I have not been able to do it with arch.
Thanks in advance

Well, i'd say pppd knows when it has been disconnected, and quits itself.
So, ensure you have the flag -detach in your pppd configuration file enabled, and configure your inittab similar to this
pd:23:respawn:/usr/sbin/pppd
This would ensure to reconnect when the pppd daemon quits. This might not be the proper arch way to go, but it should work
That's the commandline version, if you are running KDE, kppp has a reconnect method for pppd.
The other way would be to write a small shell or perl script to check if the daemon is running or if you still have a connection up.
Hope it helps

How to make CD track markers when exporting multiple tracks from one track

I have been remixing a soundtrack on one track. I have imported in many tracks and worked on them as one project and now I'd like to export them as seperate tracks by giving them track markers. I've been reading the manual and this forum but haven't found anything about it. I also wanted to use Logic to clean up some old vinyl records and export them as CDs. Help please.

How Long Will Arch last?

Hi, my question here is not to ridicule (or otherwise designed to offend anyone) but one of concern. Many distributions have a viable economic model which helps ensure that the distro can survive (Fedora is one prime example). The fact that Fedora has the backing of Red Hat means that it is almost always asured funding. Ubuntu is also moving in this general direction (although their model does not seem as reliable as Red Hat's yet.) What gurrantee do we have that Arch can last for many decades to come? The Arch devs are real people with real jobs. As far as I know they do not actually get and money from Arch Linux. What sustains Arch ( pays for servers etc.) Is it simply donations? Can Arch survive soley off of donations?
What are your thoughts and ideas do you have on how to make Arch a self sustaining distro while also keeping it free? Finally if Arch falls apart what would you do?
THIS IS HYPOTHETICAL THIS IN NO MEANS IMPLIES THAT ARCH IS GOING UNDER ANY TIME SOON!
( I would also like to take this time to conragulate the Arch devs for coming this far and thank them for all their work it is much appreciated.)

Gullible Jones wrote:... There's also Unununium (no kernel, damned if I know how!) ...
Read the FAQ (Introduction page) for more info about Unununium:
http://unununium.org/introduction
Something interesting:
On what platforms does Unununium run?
The latest plan is to implement Unununium as a Linux userspace process. Linux is a stable, available, well documented program which eliminates most of the mundane, uncreative aspects of usual OS development such as writing hardware drivers. It also provides an easy mode of execution, with a developed debugger such as gdb, and fast boot times, since there is no need for a full hardware reboot. This makes development much easier.
Running on Linux has disadvantages as well. Probably most significantly, some things are slower. For a slower speed in execution, we get a faster speed in development. Some day it would be nice to reduce overhead, but that's something that will wait until there is something running.
For some reason or another, this choice of platform leads people to question if Unununium can really be an OS. Of course, it really depends on how "OS" is defined. Unununium is an environment and a design common to all programs which depend on it, and in this sense might be considered an OS.

How to make a commentary track in iDVD and iMovie 6

Could someone please explain how to make a commentary track using iMovie6 and iDVD? I think I will be able to import the commentary track onto the second sound track in iMovie 6 with no problem. I just can't figure out how to make it an optional track in the final DVD.

Yes, you can put the commentary track on the second sound track in 06. You can also attach a mic and make the commentary as a recording. I will caution that you will need to depress any original sounds associated with the film so that it does not sound like a garbled mess with both tracks competing. I imagine you know how to grab the volume level line in the audio track and nudge it lower or higher?
I also don't see any other option than including two versions of the film on the DVD. Pretty simple fix if it will fit... I would export the plain film first before adding the other audio (or you can simply uncheck one of the audio tracks while exporting to mute it).
