  1. I would also suggest Synergy, because you are adding a laptop into the mix. With a KVM, you would also typically have to switch the video feed to your monitor to change the computer you are controlling. With synergy, you would be able to leave your desktop on it's monitor and be able to see both machines at the same time, which I assume is what you want. -Light
  2. Two companies I have seen recommended are BatchPCB (Haven't heard of outside of the following article) and PCB-Pool(Seen advertised in a magazine (Nuts and Volts)). There is a write-up on a site called HackADay which talks about creating the gerber files, and they are both mentioned there. The writeup from HackADay is here. The reason that I mention these two companies is that they take designs from multiple people and collect them together, so one person doesn't have to buy the whole plate. You just pay by the square inch, and the turn-around times are ok for non critical things. I will also plug the toner transfer method, as I have had very good luck making boards that way for quite a few years now, and have also done double sided boards with no problems. My only advice for making your own boards is get some micro drill bits (Harbor Freight sells them fairly cheap) to drill holes for through hole components and use a drill press as these bits break very easily. Second, use a carbide grit blade to cut the PCB material. It will eat normal blades very quickly. (Normal jigsaw blades might last 2 to 3 inches) Overall, if the board has some tiny traces and is rather complicated, you might be better off just ordering it. If you see yourself trying to make boards in the future though, it might be worth wile to learn the toner transfer method. If you have any questions about either route let me know. -Light
  3. This looks like it would do the trick, but boy is it expensive. This would let you put the signal on any channel you want, not just on channel 3/4. This is similar to what they use at gyms to make custom MATV systems - they take 10-15 direcTV receivers and feed them into a system like this to make a custom TV network. -Light
  4. I'll do my best to try answering a few of your questions, at least somewhat: 1) One way to find out your external IP address (the one that someone can connect to you from the internet on) is to go to websites such as or (my preference). Also, in most routers, there is a page which displays status information which generally has your external IP listed. Can't say much more than Swerve on 2 or 3. 4) The IP address starting with 89 is what is called your external IP address. The address starting with 192 is your internal (local) address. The difference is that your external address, anyone on the internet can see, where your internal address can only be seen by computers on the same network as you. Your router typically translates between these two addresses by doing Network Address Translation (NAT). This lets multiple computers use the same external IP address. 5) A modem and a router are vastly different things. A router talks between two computer networks and deals with digital data. A modem is a device with uses a telephone line to allow a computer to send data from one modem to another by converting digital data into analog audio tones and back again at the other end. There is no way to make a router do things like dial numbers or talk to a modem. -Light Edit: Ohm beat me to a couple points.
  5. So - it finally all works. I think it was ultimately a combination of C'thulhu's tip, wiping the partition table clean with fdisk (yet again) and finding out that there was a floppy disk in the A drive by trying to insert the DOS boot disk made for running the fdisk /mbr Removing the disk from the floppy drive actually wasn't the cure to the problem as it left me with another reboot message on a clear screen along the lines of 'REBOOT COMPUTER NOW ... PRESS ANY KEY TO CONTINUE'. So, after re-re-installing Windows XP, the system is finally up and running. Thank you all for the help and prompt responses. -light
  6. So, I am trying to setup my old desktop as a server for LAN parties and I figured that it would be best to start clean. So I put in two HDD's (Primary = 400GB Western Digital, Secondary = 10 GB SpinPoint) and tried to install an old copy of Win 2K from the VLK backup disk that came with an old laptop of mine. The installer appeared to run fine, said that Win 2K had been installed and to reboot for the next phase of install - upon reboot, BIOS recognized all drives in the machine, but proclaims "Boot failed". So, I try the process again with the actual Win XP factory install recovery disks that came with the computer. They say that they are going to re-partition the drive, and then proceed to restore the drive to 'factory' state. The recovery installer displays a confirmation that the restore has been successful. Upon reboot, the same condition occurs. Knoppix will boot and see the drives; however, it won't mount them at all. fdisk will read the partition table, and I have checked with that that only the first partition of the first drive is marked as bootable. The BIOS has the first drive marked as the boot drive as well. As a side note - the 400GB drive (the one I am trying to boot from) should have had FreeNAS on it to begin with (the last use of this box) and when I first got the box out and tried to boot it, it also failed to boot then. I am racking my brain trying to figure out why this install is failing, as I know that this box was working OK the last time I tried to use it a few months ago (with FreeNAS). I have also tried disconnecting the secondary hard drive and setting the WD to master - single drive, but am still getting the same problem. Any help is greatly appreciated. -light
  7. My college has some interesting clusters. They try to theme each of them and I know of at least the junkfood (hoho and jolt are two from there) and spice girl (they only used four of them: scary, posh, baby, and sporty) clusters. Personally, my computers at home are named by their purpose (NAS, SRV, WKS(workstation), WAP, LAP) and a number. Eventually, I may try to do something more interesting. -Light
  8. I just go buy whatever butane RiteAid has. (I think it is Ronson Multi-Fill?) It has never given me any problems, although Weller would like you to think that you need to use theirs. -Light
  9. I think what you are looking for is Cygwin. It is a program for Windows which acts as a linux command line system. It will allow you to install and use most linux programs fairly easily. I have used it with perl before and had good results. EDIT: I think it is worth noting that you would do all of your execution in Cygwin, although you could edit with a program running in Windows by accessing the folder directly. (Cygwin sets up a file folder structure based in C:\Cygwin by default) -Light
  10. I use a Weller Pyropen WSTA3 quite often, and I have never had any bad experiences with it. I have had it for probably close to 10 years now and I have only needed to change the catalyst twice. It is a great iron for smaller things; however, I don't know how well it would work for large wires (#8 and larger) as I don't really ever use it with wire that big. One feature is that the exhaust only exits on one side, so that you can direct it away from something that it might burn. I have had problems with other cheeper butane irons burning or lighting stuff on fire with the exhaust gas if I am working in very tight areas. I will chime in with the anti-ColdHeat crowd. You can't do detail work with them because the tip is so large and the tips break very easily. -light
  11. Some of the DVD's have been put to YouTube in 5 minute segments, but that is the closest thing I have seen yet. They are under the user mediarchives. It actually appears that this is the company who officially filmed the talks as I remember seeing a sign at the DVD sales table with the website on it, which redirects to the YouTube page for this user. The four talks I see are from Steven Rambam, Kevin Mitnick, Jello Biafra and Adam Savage. -Light
  12. There is at least one 'real' loop still around that has two consecutive numbers, although both answer with milliwatt. It's numbers got published when a N carrier got cut over a couple years ago and people were scanning the whole exchange out. -Light
  13. I have seen similar devices on street lamps in DC. In areas where they desire increased video surveillance they will mount boxes similar to that. Some are like the one you show with only antennas. (some have patch looking antennas and some have the shortstick type, some both) Some others actually have dome cameras mounted on them. Next time I am down that way I will try to grab a picture. -Light
  14. There is also a program called PalmOrb which emulates a matrix orbital display. You can then use something such as LCDSmartie to push content to it. (This is what I do with my old Palm III) -Light
  15. I will certainly be there. I'll also be there Thursday and Monday for A/V stuff if anyone is around.
