Re: Settings for a Graphics Card HELP

You had an old graphics card and replaced it? Or is this a system you have just built? If old replaced with new, then I think that the old software and drivers are confusing the computer. Try uninstalling and removing all the graphics software and drivers, both old and new. Download the most current...

Re: dell computer problem

Dacflyer, Just a wild guess, but have you installed/updated all the drivers, especially the chipset & video drivers? It sounds like the computer is trying to use the CPU for video processing. As I said, just a guess, trying to help. Also, please post the your dell's model number, and the make/mo...

Re: Would the US electrical code allow this ?

No, code will not allow this. Depending on how much light you need, would a lighted switch work for you? I've seen both the old-school lighted toggles and new "decora" style lighted. The only sticky part is that the switch box itself (in the wall) must have a neutral for the "light&qu...

Re: computer to computer USB connection

Several moving parts here. 1. Set both computers to use the same Workgroup name. 2. For XP, enable file and folder sharing. If memory serves, this will open the firewall ports, if not, you can temporarily turn off the firewall. Go to Control Panel, then Network Connections. Next, right-click on your...

Re: 555 timer circuit for servos

Just a couple of ideas. First, you may need to look at your power supply. I'm thinking the new servo is just a little more than your supply can handle. Can you measure your power voltage with no load, then with the new servo moving? If you see a large drop, you need a higher-current supply. (Or your...

Re: Web Server on Win98SE?

I like the idea of re-purposing the computers, but I wouldn't use Win 98SE with such an old Microsoft web server on them. I'm assuming you just want to do your initial development and testing on these computers, to be rendered with IE 7/8 and Firefox on the clients. Check with your ISP, as many don'...

Re: vga

On most laptops, there a special key sequence to toggle internal/external displays. On my Dell Inspiron, it's the blue function key "Fn" and "F8" together.

Re: Moving everything from one machine to another.....

You can't get around the OS and application re-install, especailly if the hardware is differenet, but there are easier ways to move everything else from machine to machine. You didn't specify the OS, but XP and Vista have "Files and Settings Transfer" wizards. You can give those a shot. Th...

I had something similar happen with my wife's system. I think you've been caught by Vista's "you're not really an admin" thing. Even though I was logged-in as an administrator, I still had to download the program, then right-click and select "Run as Administrator." When I did thi...

Re: Help Setting Up Home Networking (again)

Amauter computer user, but a couple of ideas: Make sure that you have downloaded and installed the latest firmware update from Linksys. You may need to connect the router directly to a computer to update the firmware and for initial setup. Disconnect the other router temporarily. Make sure the DHCP ...

Re: Mass wire storage solutions

It's not pretty or elegant, but I've found that a combination of plastic storage bags and the plastic totes described above work well for me. Gallon and quart size bags are the most useful. I use one bag per cable, then sort them into the totes. I use one tote for: computer stuff, telephone stuff, p...

Re: Detecting when a specific item is near

I have to confess that I have no practical experience with these devices, I just did some research. Here are the links I used. Once you have a better idea about the parts you want to use, you can figure out who carries them. The main source seems to be Allegro Micro: http://www.allegromicro.com/en/P...

Re: Detecting when a specific item is near

I'd be tempted to go with either magnets or RFID. A Linear Hall-Effect sensor can detect the difference between the north and south poles of a magnet. Object A could have one or more magnets inside it with the north pole facing out. Object B could use the south pole of the other magnets. This will o...

Check the back of your present function generator for a GPIB interface. If it has one, it can be remotely controlled/programmed. You'll need an interface or adapter of some kind for the computer, a GPIB cable and software. Check the makers website, you may be able to find free sotfware and more info...

I'd consider an Arduino (or a clone)

I'd consider an Arduino (or a clone). It's an Atmega ATmega168 programmed with a bootloader. The development evironment is free, open-source and strongly resembles C. The code in the chip is also open source. I'm not sure how fast it is or how well it scales up, but should make a great learning plat...
