Anyone have a model or circuit for a switched power supply?

Teach in a County College and would like to include this topic in one of the electronics courses. Help is appreciated.
Steve

Thank you for your help Yi. Im using 10.0.144. Using the "Save As" function, I modified the circuit from the Averaged Model Current Mode boost to create the "Trial_Boost_CM" file. (The path is "samples/SMPS Circuits/Average Analysis") I've described the extent of my modifications with text on the schematic. I've been able to successfully simulate it with several "unknown parameters" warnings in the audit log
Using the same method, I created the "Trial_Buck_CM" file and modified it as noted on that schematic. I've also been successful (with similar warning) simulating it.
Finally, I created a third file, "Trial_MultipleConverter" from the "Trial_Boost_CM" via the "Save As" function. I added a second sheet and pasted the circuit from the "Trial_Buck_CM". When this combined circuit is simulated, the error message "...duplicated subcircuit name ...." as I mentioned previously occurs.
The error message does not appear when I delete either or both (naturally) of the CCM models. Once I place the model again yields the same result.
This also occurs if you place the models within separate Hiearchial blocks.
What am I doing wrong?

Anyone have a spare microphone cable for ibook G3 12 inch

Anyone have a spare microphone cable for ibook G3 12 inch? I pulled the wire from the connector when replacing my logic board.

Don't have a spare one lying around, but We Love Macs has a new one for sale:

PowerBook Tech parts out non-working iBooks. Although the microphone cable isn't a part he lists, Daniel may have one available for not much money if you e-mail him at the address listed on his home page.
Good luck.

Fire fox crashes and freezes if i use it too much (kind of a good thing). For example if i use stumble fire fox will start to slow down then freeze completely. Does anyone have a solution or should i just switch to chrome?

Fire fox crashes and freezes if i use it too much (kind of a good thing). For example if i use stumble fire fox will start to slow down then freeze completely. I am using windows XP pro and a pretty decent computer. All software is up to date and i do no have a virus. I have even tried to disable my add-ons and plug-ins but it did not make a difference. Does anyone have a solution or should i just switch to chrome?

If you need internet/want and apps you need a touch.
The Nano is smaller, less expoensive and has a FM radio.

Has anyone develped an EM plug-in for Cisco switches or routers

Folks,
Has anyone develped an EM plug-in for Cisco switches or routers? Please reply to this thread if you have developed one and would like to share your experience in developing this plug-in?
Thanks,

It's probably not the conversion from CMYK to RGB that's causing the problem, but color profile (ICC) embedding in Photoshop. Fireworks doesn't read color profiles. You might be able to create an action to remove the color profile in Photoshop and then batch process the images with it.

I have the first generation Time Capsule A1254, the power supply went south and I'm looking to replace it any suggestions where I might find one? Thanks

Hi,
I have the first generation Time Capsule A1254, the power supply inside went south, does anyone know where I can purchase another?
Thanks

Might be worth considering a repair of the power supply so you can keep the data on your drive.

Anyone have a tip or app for removing unwanted formatting from text on the iPad?

I have text that was created in Word, sent via email, received on my iPad. I need to get all of the hidden formatting stripped out of this text before pasting into another application. The Notes app works in plain text, but it does not strip all the formatting out of text that has been pasted into it. Anyone have a solution? I have looked at online services and searched for apps but can't seem to find anything that does this.

I also am looking for a better email client. I need the ability to use folders and have email go directly to these folders when checking email. Just sending all email to only one inbox folder is just to confusing. I like the ability to search for email but this feature only helps to a degree. An example would be... I like all my email from tennis friends on my team to go to a separate email folder. I can do this in Microsoft Outlook and this feature makes it a lot easier to view things. Right now the email client is like a physical filling cabnet that has only one folder. The email client does try to group related emails together that I don't think works very well. So far not all email from one person are being grouped together. Some are but not all so I don't know what criteria it is using to determine what is grouped together. To work better I would like every piece of email from the same person to be grouped together. But then again wouldn't it be easer to just have a separate folder for each person or group of people. The reason for this is at a glance there are so many emails in my inbox that I sometimes miss an email. Using folders would allow me to check and scan my inbox a lot easier when there are only maybe a dozen email to view.
Anyone else would like to see this feature?

Anyone have a DVD player script for playing clips?

I'm new to Applescript and I'm trying to find or write a simple script for playing video clips in DVD Player in a row, so that I don't have to watch a clip, then minimize the play window, then select the next clip from the Go menu. I have four clips that I would like to play back to back. This doesn't seem like it would be too hard to do, but for the life of me, I can't figure it out.
Anyone have some advice (or a pre-written script) for a pathetic newbie?
PowerBook G4 Mac OS X (10.4.7)

I think maybe I wasn't clear enough in my original question. These aren't clips that I have saved on my computer or clips that are on the DVD itself, they are just clips I set using DVD Player (using the New Video Clip command in the Control menu).
The problem is that the DVD has no chapter markings. The entire 82 minute film is one chapter. We have permission from the producer to show only segments of the film, so I created clips in DVD player of the parts I want to show. However, right now, I can only play them one at a time and then have to minimize the display area and go to the Go menu and select the next video clip. I have four named video clips set for the DVD. I would like to write a script that I could run that would play them all in a row.
I feel like I must just be missing something obvious.
It seems to be that the script should just be
tell application "DVD player"
activate
play named video clip "background"
play named video clip "Cizik"
play named video clip "Durley"
play named video clip "end"
end tell
but that's not working. The clips show in the Video Clips window (if I go to the Go menu), so evidently the computer knows they're there, but basically nothing happens if I try to run that script except 1.852402768E+9 showing up in the Result window (I feel like I should know what that means, but of course I don't).
Is there some trick for directing it to the clips that I'm missing? Or some other command I need to put in first?

I have a 1st Gen Time Capsule 1tb. It turns on, boots up and turns green for 5-10 mins, but then turns solid orange and then blinks orange. I have removed the hard drive and replaced the power supply . . . still the same problem. Suggestions?

I purchased a used 1st Gen Time Capsule with a 1 tb hard drive.
When I plugged it in and did the initial setup, it worked fine, but gave me a hard drive error. A few minutes later the green light turned solid orange, then blinking orange, then the status light went off. The lights in back stayed on.
I removed the hard drive and rebooted, it turned green for 5-10 minutes then reverted back to a solid orange, blinking orange, then went off.
Next I purchased a remanufactured internal power supply, and installed it (without the hard drive in). It turned green almost immediately. After about 15-20 minutes, I decided to try to install the hard drive again, booted it up, and tried to erase the hard drive with was working properly according to the software. It stopped erasing the disc after about 20 minutes and turned solid orange again, then blinking, then no status light (but back lights were still lit).
I'm a bit flabbergasted at this point, any suggestions on what to do next? I think i've pretty much replaced everything except the logic board, but can't seem to find any information on the symptoms of a logic board malfunction.
Thanks!!!!!!!

A Gen3 is identical board to a Gen4 although they have some differences in firmware and wireless card was updated on every model.. but a Gen3 is substantially faster than Gen1, Gen2 which also have identical boards.
You can with careful shopping get a Gen3 pretty cheap.
Most use a delta power supply which I think is a lot better than the flextronics used in most Gen1/2
You can sell back the parts to ebay.. people still would buy the power supply etc. Even just the case can be useful to a repairer.
But if the board is gone.. it is hard to repair.. not impossible.. but hard.
Gen 3 and Gen 4 are not without faults.
See this page.
https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair/new-issue-with-a1355-gen-3-tc
I have fixed it a different way.. by using the small converters you can buy in bulk from ebay for $1 each.. KIS3R33 .. they produce 3.3V at 2A peaking at 3A.. amazing.. I keep using them to replace onboard power converters by removing the inductor and simply power directly.. the end result has worked great. You can simply change the resistors around and get any output from 1v to 20v depending on input.
Is it worth doing it .. no of course not.. it will waste many more hours than $50 is worth.. but it is kind of fun that you can actually make things work again.
Here is a pic of the Gen 3 totally powered by me. All onboard power removed.
This was to track down the fault in the Gen3.. but I am kind of pleased that it ended up neat enough and reliable enough to work for more than a year.. the Gen3 still serves as a way to get Netflix via network for a friend running 24/7.
The units supply (from left to right)
1v, 1.1v, 3.3v, 5v, 1.8v
It is feed by 12v supply which is also directly connected to the hard disk.
So it is possible to fix.. !! Only got to be a bit crazy.

Labview drivers for sorensen dlm power supply

I am looking for a LabVIEW driver for a Sorensen DLM 150-4 power supply. I am using ethernet to communicate with it. Can anyone help me?
Thanks.

Sorensen probably changed the firmware to more compliant with LXI specs. It's nice that they finally adopted SCPI but it's too bad they didn't maintain backward compatability to their older models. I wonder what they are telling their customers with an installed base of the GPIB instruments that might want to buy the new model. In theory, I suppose you could use the existing driver as a starting point and replace the old commands with the SCPI ones. I only have GPIB models so I can't be of much help there. Have you checked with Sorensen to see if they have a new driver? If you do create a new driver, please post it so others can benefit.

Looking for Apple TV power supply - any ideas?

Hi folks,
My out of warranty Apple TV has an obvious power supply problem (it's totally dead, no power up whatsoever).
There are a few websites that have tutorials on replacing the power supply (or hard drive, etc...).
The problem is I can't find a place to purchase a replacement power supply.
It's a Delta Electronics ADP-36BF, Apple part # 614-0395 (http://s1.guide-images.ifixit.com/igi/HGslJDZeqPnKlFVD.huge)
Any ideas on where to find one?
If I can't get it myself to replace it, I'll probably just wait for the Boxee Box to replace it.
Thanks.

I'm in the exact same boat -- I've looked everywhere and can't find anything. I've even called Delta Electronics about the part and they said they can only sell them to Apple. If you find anything out please let me know! Thanks.
