Hey
I have a SAPI application that works great locally. Input via the microphone and output using TTS all work great sitting in front of the PC.
What I'd like to do is operate this application remotely, via a walkie-talkie. Do any of you know if a device exists that could plug into my sound card and receive transmissions and pipe the audio into the mike jack, and take speaker output and transmit it via RF to the walkie-talkie?
I don't even know what that sort of device would be called, so I can't search for it.
Any advice appreciated. Thanks.

Nice idea but it as a large flaw. How is the remote machine going to "Push to Talk"? WT's normally can only receive or transmit at any one time, not both at the same time.
I'm sure you'll find some hardware to do it using a full duplex WT, but there remains the issue of having the machine "Push to talk". Or do you want it to transmit continuously, even if the machine has nothing to "say"?

Yeah, I know. I can't help but think this has been solved already though.

I didn't think walkie-talkies could be full duplex since the mike is so close to the speaker (I imagine a headset type device could be), but I don't really care whether it transmits continuously, as long as it can listen at the same time (full duplex, like you say).
Any idea what that hardware would be called? I'd even settle for a one-way conversation. A device that converted radio to audio and piped it into the mike jack of the sound card.
Thanks again.

Yeah, by custom hardware. You're most assuredly not going to plug a WT's linein and lineout to a sound card and get away with this. This would be some kind of hardware that would interface with the radio and then plug into the PC somehow. I'd be willing to bet you'd find something like this around the HAM Radio crowd, or possibly even the manufacturer of the radios.

Actually, you could always use "Lego Mindstorms" or a similar kit to rig something up that physically presses the talk-button on your radio whenever the computer raises a flag.
Actually, a Servo might just do the trick.

Possibly, but the question then becomes "are the parts going to last for the life of the application?"

There might be an adaptive firewall, e.g. the first two pings are considered "harmless" and are replied to, the next two are considered an "attack" and silently dropped. Thats one explanation for the ping failure, but it is just a guess. ebay.com could also be blocked by your ISP/company.
Cheers,
Sebastian

thanks for yr responce...
actually this is my home pc so there is no external security..eg server or router...and plz let me know what is this adptive firewall..is it normal or some thing special...i have been using my comp with same setup since more than one year... on one of the forum i read that it could be issue with ISP subnet setting...could it be ?

Try pathping. It will try to tracert over an extended time and collect statistics on each leg of the journey. That should help identify where the block is located, though I wish you luck getting anyone to respond if you point it out.

append a parameter that will give you more time to ping. One of the options is the time in milliseconds. Increase it to something like 10 or 30 seconds and see if it succeeds.

I picked one of these up recently as a 'clearance' bargain in a local electronics store, and the original software supplied doesn't work on XPSP2. There is a 'fixed' version of the software on the manufacturer's site, but that doesn't work correctly, since when editing the phone book, it loses the last digit of each stored number (!).
It's a USB plug-in with a Pacific USB<->serial converter built-in. Does anyone know how I can get hold of programming information for whatever is on the other side, or is there a standard IC that I could send AT style commands to?
I could just throw it away, but heck, I write software for a living...

I want to capture buttons events from my wireless presenter 8000. Not the "normal" left- and right-click, but the special Buttons for presentations (in PowerPoint these are mapped to next/previous) slide. There are also two buttons for loudness increase/decrease and one to hide the screen.
Google did'nt show anything helpful for me. Hope someone here knows about this.

I have a little problem with networking my home computers. I have installed network adapters on a cross-cabled manner in two of my home PCs. I needed the networking wire to run around the outer walls of my house (as opposed to internally running those cables, since the rooms are on two different flats). The problem is that I bought a certain length of wire, but found it a little short to reach across the two PCs. So I had to buy a little more wire, and I manually joined the wires by scraping off the outer covers, and then twisting the exposed wires, and taping at the connection point. This worked perfectly for some time, until recently, when the connection seems to be loosened at the joint. Now, whenever both the computers are booted up, the status indication keeps changing from "Connected at 100 Mbps" to "Cable Disconnected", and I have to keep pressing at the connection point to (temporarily) get the connection working.
It has been two to three times that I have removed the tape, and then reconnected the wires by further scraping the wires. I am sick and tired of doing this.
My question is: Is there any way to connect the wires (I mean, do we get a RJ-45 connector for connecting two wires? Or is there some other solution to my woes? I have kept the option of buying off the whole length of the wire as a last option. Please suggest a solution to this problem.

I don't think you understood my problem. The wire's hanging in mid-air...how do I solder that???
If you're recommending using a protoboard or something similar to act as a base for connecting the wires, well, i tried it, but it wouldn't work.....
Actually, I was wondering if there was some kind of connector, similar to a power socket connector for extension cords.......

It sounded, from your description, that you stripped the wires and twisted them together, covering the joints with tape for insulation - and that worked until they worked themselves loose. My thought was to remove the tape, clean and re-twist the connections, heat the stripped and twisted ends with a soldering iron, apply some solder, and then re-tape. No protoboard or any other device necessary.

Here, it sounds like you want a less permanent connection. Just get male/female connectors similar to the ones on the ends of cable and make a joint that way. Be sure the connectors you get are "straight thru"; that is, make sure they don't flip any of the wires.

Ok, I wonder why I didn't think of that....
Also, about the male/female connection that you talk about, I have only known of such connectors for RJ-11 types, i.e. for phone lines. Are they also available for RJ-45 connectors? It'd be great if that were the case....
Lots of thanks to The Grand Negus for such insighful responses, BTW....

This [^] is the easy way. And the "Cyberguys", if you can get them to ship to your location, are typically dirt cheap compared to other vendors.

Thanks a lot for the link.
Now if I could only find some way of placing an order for them to get that thing here to Nepal......

Since it's unlikely that you can just run down the mountain to the local computer store for a hub, the solder choice seems most appropriate. In fact, it makes a better connection than a RJ-45 connector.

Simple solution - get a longer piece of CAT-5. BTW, did you use CAT-5 certified for outside use (yes, there is such a thing)? Did you also know that the maximum length of any piece of CAT-5 should be no more than 325 feet? Here's an even better idea - go wireless.

No man....the suggestions seem to somehow resemble with one of your signature lines ::

I mean, i thought i mentioned i did not want to buy a new length of wire....and no way i'm going wireless....the cost factor is way over the projected one(which is nothing  , or very low)
