74ls153 -- trying to make a full adder

I am trying to build a full adder using a 74ls153 chip. The chip was part of the specification. No luck so far. Any ideas?

Hello,
One thing I noticed is that your circuit is not grounded. You need to add GND to the negative terminal of the 5V power source.
For reference here you can find some configuration using the 74153 IC.

I'm trying to make a time sheet and include a grid, but I'm having a hard time figuring out how to print a full grid on my spreadsheet. There are options for shaded grids but I want a defined grid, and I have spent the last 2 hours looking for the answer

Hi Cynthia,
Are you planning to have this table do any of the calculation, or is is to be used as the electronic equivalent of a sheet of paper with a grid printed on it—a place to record the data.
For your seven column table:
Are you using one or more rows at the top of the table to label the data below? If so, you might want this row (or these rows) to be set as Header Rows.
Are you using the leftmost column to label the rows? If so, you may want this column to be a Header column.
The default table supplied on the "Blank" templates contains one header row and one header column. If you need more (or fewer) Header rows or columns, select the table, then go Table (menu) > Header Rows > (choose the number you need). Repeat to set the number of Header Columns.
To make a seven column table from the table supplied by default, click on any cell in column H (The eighth column), and drag right to add more cells to the selection, until you get to the last column of the table. With these cells selected, Go Table > Delete Columns.
To make the remaining seven columns fit across a single page:
Go View > Show Print View to show the table as it would appear when printed to paper.
Select the table by clicking its icon in the Sheets List to the left (easy method), OR by carefully clicking on the outside boundary of the table itself (fiddley method).
With the table selected, you will see square white handles at each corner and at the middle of each side (including the top and bottom).
With the mouse, grab the handle in the middle of the right side of the table and drag right (or left) until the table just fits onto the width of the defined page.
With the table still selected, set the thickness and colour of the cell boundaries using the Gaphics Inspector (as described by Jerry), or using the Stroke, Thickness and Color Well controls in the Format bar above the working portion of the Window.

Barry

I am trying to do a full Time Machine Backup to a new external disk. The backup starts, and it says "Time remaining about 4 days." That seems like a very long time, but the real problem is that the computer "logs off" after a few hours, and the b.u. stops

I am trying to do a full Time Machine Backup to a new external disk. The backup starts, and it says "Time remaining about 4 days." That seems like a very long time, but the real problem is that the computer "logs off" after a few hours, and the backup stops. The system preferences are set to "Never" for Computer sleep and Display sleep. The computer does not ordinarily log off automatically, but it has done this twice since I started the Time Machine backup.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If all you see are messages that contain the word "Starting," you didn't clear the search box.
If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Some personal information, such as the names of your files, may be included — anonymize before posting.

I tried to make a second library, but my first one was deleted so I did it again but now I have doubles of every song. How do I restore my itunes back to the way it was before I tried to make a 2nd library?

Like I said I tryed to make another library, I did what Itunes told me to do but it only erased the library I had and made a new one. So I did it again but I now have duplicates of every song. How do I get my it back to the way it was, before I tried to make a second library?

C:\Users\Cheye\Music\iTunes should be the original library. You should be able to connect to it as follows.
Close iTunes, wait a few seconds, click the icon that starts iTunes and immediately press and hold down the shift key. Keep holding until asked to choose or create a library. Click choose and browse to the file C:\Users\Cheye\Music\iTunes\iTunes Library.itl.
Depending upon exactly what you did this has either restored your library, or done absolutely nothing at all. That was the reason for asking you to check using the script.
Assuming you still have a library full of dupes there are a number of ways to go. I've written a script called DeDuper which can help remove unwanted duplicates which I discuss in some detail in this thread. While it should work it will be ideal if it discards the copies that are outside the media folder C:\Users\Cheye\Music\iTunes\iTunes\iTunes Media. I've a feeling it will do exactly that, but it depends in part on exactly you got into this mess. It would be worth doing a few sample runs of just a few sets of duplicate files first.

How to make a full backup of my iPad without using iTunes

I need to make a full backup of my iPad. I am using the Vudu app and have many movies downloaded to my iPad. I have performed a backup of my iPad from iTunes onto my Macbook Pro. The mobile backup files on my laptop are not nearly big enough for the 20+ movies (at lease 1/2 to1 GB each). Because of this I do not believe iTunes has made a full backup including the movies. I want to avoid having to re-download all the movies if/when the iPad drive fails. I want a complete backup such as Time Machine or using some other external hard drive or app on my MacBook Pro.
I bought a Seagate Wireless Plus 1TB Mobile Cloud Storage with Built-in WiFi Streaming (STCK1000100) external hard drive and installed the Seagate Media App. I can, via the app on the iPad, see the device and copy to and from it. But, it only allows access to music, movies in iTunes (not any movies in Vudu), and things like documents on my iPad. It does not allow access to all the files inclding system files stored on the iPad. I also tried another Seagate non wireless external drive that I connected directly to the iPad but the Seagate Media app does not communicate with or recognize the device from the iPad.
I also bought DiskAid software that supposedly will make a complete backup of an App on a mobile device and installed it on my laptop. I was able to make a complete backup of the Vudu app from the iPad onto my laptop, but in a test could not restore it to my iPad. The backup file, though, was the right size, about 26 GB. The DiskAid techs are looking into that. I was able to use DiskAid to backup another app in a test (Hertz). That app made a backup of the Hertz app onto my laptop, I deleted the app on my iPad, then I was able to restore it. But right now the restore option is not working for Vudu.
Another option would be to copy the movie files off of the iPad onto my Laptop, but the iPad does not appear in the finder window on the Laptop.
I have about decided my MacBook Pro laptop will have to be the main repository for all the downloaded movies, since I can make a Time Machine backup of everything.
It is very frustrating to not be able to make a full backup of everything on my iPad.
Anyone else have any ideas? Apple - when are you going to provide a way to make a full backup of an iPad?

I recommend Super Duper as well. I use it batch mode to automatically back up my iMAC every night at 2 am. It's saved my life a couple of times- once my disk crashed (under warranty)and what could have been a disaster (1000's of irreplaceable photos) was a 2 day inconvenience.
Now and then I boot up from my backup on my firewire drive, wipe, check and reformat my internal hard disk, copy back all my files and I'm good to go

Trying to make a slideshow of image with iMovie

Trying to make a slideshow of images for clients. Images are good quality images (5616x3744), edited in Lightroom.
As soon as I import the images in iMovie, I see a clear degradations in quality. All the blacks are full of pixels. Impossible to work with.
I can't even imagine the export that this file would suffer in term of quality.
I did change in Preferences - Video : Import video in HD format. I've tried both options. Doesn't change a thing.
Anyone? Am I a fool to think that iMovie should be doing a better job at handling those files ?
Let me know !
Thanks !

Hi
(5616x3744)
• is a far higher resolution than iMovie can handle
• downscaling is done badly in iMovie
• is far more resolution that any screen / Projector I know of can show
• and if You go for a DVD as result the quality loss will be even worse
iMovie - should be able to handle 1920x1080 (at it's best I guess)
DVD is as standard - interlaced SD-Video (at it's best)
• NTSC (29.97fps) 520 lines - about 640x480 pixels (square) 720x480 rectangular (narrow) pixels
• PAL (25 fps) 625 lines - about 768x576 pixels (square) 720x576 rectangular (narrow) pixels
If iMovie'08 to 11 is used in a DVD process then 50% of SD-Video quality is lost as they all discard every second line in the picture.
So when I do my SlideShows I do
• Use iMovie HD6 or FinalCut any version - as they deliver max (100% interlaced SD-Video) to DVD authoring software
• FotoMagico™ - included in Roxio Toast™ bundle - then burn as Blu-Ray (on standard DVDs - CAN ONLY be played on BD-Players as PlayStation3 (not even on the Mac))

Trying to make a calendar and every picture is coming up too low of quality

I am trying to make a calendar for my mom's Christmas present, but every picture I put in the calendar to be the month's picture has a caution box in the corner and says "This photo may print at too low of quality". I just don't know if this is normal with using your own pictures but I don't want to spend the money on this calendar and then it not turn out very good. Please let me know what you have done or if there is anything to do.

Welcome to the Apple Discussions. What are the pixel dimensions of the pics you're trying to use?
I ran a test on a calendar using the picture theme and for a full page photo to avoid the warning triangle it must be approximately 1535 px x 1181 px or roughly 120 dpi.
You'll have to decide how far below that level those pictures are and decide if it's worth the gamble. Or use layouts which have more photos per page and thus require smaller sizes.

Where are you located?
Just go and buy an iTunes gift card at any store in your country.
Then follow all the steps you did, but when it asks you for the credit card number, there shoujld be a GIFT CARD option which will let you load your account witht eh funds form the gift card without providing a credit/debit card #.

Yes, many know what this means. You can too. Just type in "error 1004" in the search box at the top of this page. Or, just look to the right. You'll find many links in the "More Like This" box.
Always good forum etiquette to search for previous posts on the topic before posting.

Trying to make a DVD with an old/non-existent version of iDVD!

Ladies and Gentlemen,
Please could you help me?
I work at a school in the UK, and have recently been able to purchase an external Lacie DVD drive, as the school’s computer (currently an iBook G4 with OSX 10.3.2 and a 1GHZ Power PC Processor – 640 MB Memory and a 40 GB HD) wasn’t shipped with one – however, I have a problem…
Trying to make a DVD that will play in a stand-alone DVD player – I followed the advice in iMovie Help – but was stopped suddenly on finding that I do not have the relevant version of iDVD (which version (if any – I can’t see it anywhere!) was shipped with iMovie 4.0?). Is it possible to download a copy of iDVD 3 or later from anywhere compatible with OSX 10.3.2 and iMovie 4.0?
The iMovie Help has an additional option to ‘export your movie in a format appropriate for DVD authoring’ which has let me burn the movie as a (name).DV file – but this is not compatible with any DVD player I have tried. I noticed a while ago on this forum that someone was talking about Toast but I do not have this, but I do have Roxio Easy Media Creator 7, which was bundled with the burner – but is only compatible with a PC – would I be able to build a project in iMovie, transfer it to a PC, and use REMC7 to do what toast would?
Finally, I was wondering if anyone has any experience of using Avid’s free DV software – and if they would recommend it (and also if I would be able to make DVDs with it?).
Well thanks for reading if you got this far – and I’d appreciate it if you could offer any advice (I know I’ve not been very concise)…
Kevin.
iBook G4 Mac OS X (10.3.2)

Thanks for the welcome Karsten! I’ve checked the installer disks – which appear to have all the main pieces of software, but not iDVD. If you or anyone knows where it might be hidden that would be great. Thanks for all the other info too!
Thanks Lennart – I don’t think my computer could support iLife ’05 as it is running Mac OSX 10.3.2 and I’ve just been looking at its system requirements which state it requires 10.3.4 minimum – if you know differently, please let me know. As an alternative I have considered getting iLife ’04, but your comment about iLife ’05 being the first version to support external drives worried me (“iDVD 5 is the first iDVD version that officially supports external burners“ does this mean there is an unofficial option for iLife ‘04? Perhaps a patch similar to the one mentioned by Karsten), does that mean iLife ’04 would not support an external Lacie DVD writer?
What is the earliest version of Toast I’d be able to use (as a money saving option!)?
Thank you both, and apoligies for my amateurish questions…
Kevin.

I am trying to remove two full page black borders from my Pages document and when I click on them they are greyed out

I am trying to remove 2 full page size black borders in my pages document and whn i click on them they show greyed x's but i cannot manipulate or remove them. What to do?

John,
While the grayed x corners are showing, Arrange > Unlock.
Now you will be able to manipulate or delete the borders.
