• Are there any Multifunction printer/scanners with duplex and long document scanning?

  - by zimmer62

  Do any of the $200 or less multifunction printer / scanners support duplex scanning, and possibly long page scanning? Features I'm looking for in a scanner are: Duplex scanning (scan's both sides) ADF (Document feeder allowing a stack of documents) Long page scanning (legal documents or very long receipts) Good quality for pictures The printer side isn't as important, and in fact if there was a good scanner that did the above well I could do without the printer. I suppose $200 isn't a hard limit, just what I'm aiming for.

• Is there a historical computer peripherals or accessories museum or even just a current list?

  - by zimmer62

  Thinking about all the unique and different peripherals I've owned over the years, from ISA capture cards, to parallel port controlled shutter glasses for 3d games. I've seen many many accessory or computer peripherals come and go. The nostalgia of these things is a lot of fun. I tried to find some sort of historical time-line or list but what mostly turned up is computers themselves. I'm more interested in the mice, scanners, the weird adapters that shouldn't exist, short run very rare products, strange devices from computer shows in the 80's and 90's... Hardware you might find in a geeks basement that would be completely useless now, but was the coolest thing around when it was new. An example would be a drawing tablet I had for my TI-99 computer, or the audio tape player accessory for a C64 which let you save files to audio tapes, An ISA card that did the same for PC's hooked up to a VCR. Remember that IBM-PC Jr upgrade kit, that added a floppy drive, more memory and the AT switch in the back? I'd love to find either a wiki, or a list that has already been assembled which contain many of these weird (or common) accessories. I've had so many over the years I suppose I could start a wiki here if such a list doesn't already exist.

• Best way to patch (8) RJ45 ports from one room to another.

  - by zimmer62

  I have a 48 port patch panel in my basement, which I've wired almost all of them to various rooms around the house. Many are not actually being used at the moment, but pretty much all of them are wired to somewhere. As of recent, I've put in an HTPC in my media closet (different room), and I'm finding I need a lot more RJ45 plugs to this area. I have 4 drops here, and adding a switch will not solve my problems. I'm using the cabling for other things such as IR and Serial devices, not just Ethernet. What I'm hoping to do is add an 8 port panel in that media closet, and tie those into an 8 port panel on my rack next to the 48 port... What I don't want to do is pull 8 separate cables one by one from one area to the other unless someone has a technique that will allow me to do that quickly, and painlessly. Do they make cables with more conductors specifically for this purpose? Or patch panels that are designed for a special cable essentially just extending ports from one room to another?

• Synced audio ouput on multiple machines? VLC? hardware solutions?

  - by zimmer62

  I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

• Can I set the base path outside of my application directory when binding an image source path to a r

  - by zimmer62

  So I'm trying to display an image that is ouside the path of my application. I only have a relative image path such as "images/background.png" but my images are somewhere else, I might want to choose that base location at runtime so that the binding maps to the proper folder. Such as "e:\data\images\background.png" or "e:\data\theme\images\background.png" <Image Source="{Binding Path=ImagePathWithRelativePath}"/> Is there any way to specify either in XAML or code behind a base directory for those images?

• Will WCF allow me to use object references across boundries on objects that implement INotifyPropert

  - by zimmer62

  So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged. I've built a UI in WPF and it works great, showing me real time updating when the hardware changes and allows me to send changes to the hardware as well by changing these properties using bindings. What I'm hoping is that I can run the UI on a different machine than what the hardware is hooked up to without a lot of wiring up of events. Possibly even allow multiple UI's to connect to the same service and interact with this hardware. So far I understand I'm going to need to create a WCF service. I'm trying to figure out if I'll be able to pass a reference to an object created at the service to the client leaving events intact. So that the UI will really just be bound to a remote object. Am I moving the right direction with WCF? Also I see tons of examples for WCF in C#, are there any good practical use examples in VB that might be along the lines of what I'm trying to do?

• Dispatcher.CheckAccess() isn't working from my console application, is there a better way.

  - by zimmer62

  I wrote an application in WPF / VB and separated the business logic and UI into different projects. The business layer uses a serial port which runs on a different thread, Now that I'm trying to write a command line interface for the same business layer, it seems to fail when .Invoke() is called. (no error, just doesn't work) I'm pretty sure the reason I had to add in checkaccess and .invoke was because I have collections that would be changed during processing the serial port data and wanted the NotifyCollectionChanged to be handled by WPF data binding. (The reason I'm not 100% sure is because it was months ago I wrote that part and it all worked great from the GUI, now adding the console app has made me rethink some of this) I would like my business layer to run these processes on the thread they were created, I need this to work from both my GUI version and the command line version. Am I misusing the Dispatcher in my business layer? Is there a better way to handle an event from the serial port, and then return to the main thread to processes the data?
