Google is NOT taking money for this, heck they don't want this to happen. The technique that these obessed people are using is to get as many pages as possible to have a link titled "Failure" to point to President Bush's biography. Eventually the googlebots will hit these sites and raise t...

Parallax sells a serial one for about $40 USD. That seems pretty cheap. They also sell tags for $2.25 each. RFID Reader: http://www.parallax.com/detail.asp?product_id=28140 Since you are in New Zealand, you might want to look at the reseller list at http://www.parallax.com/html_pages/company/distrib...

To estimate speeds for broadband downloads (I am not sure if the same applies for dialup due to diff packet sizes): Divide your line speed (lets say its 5000 kilobits / sec) by 8, you should get the theoretical your theoretical max download speed in kilobytes. So: 5000 kilobits / 8 = 625 kilobytes (...

I would use a tstik (http://www.tstik.com/) and write a java program to generate log files on the tstik's onboard memory and use it's built in java webserver for web access to the files. Not only that, but you could use it to initiate emails, http get requests, etc. The best thing about this device ...

Here are docs for a commercial hobby ultrasonic ranger module. The ranger is based on a 12c508. Schematics and asm source code are also included.<p>http://www.robot-electronics.co.uk/htm/srf04tech.htm<p>It would probably be easier to just buy the ready made module.<p>Harrison

The speaker probably uses a simple full wave bridge with filter caps. This allows both dc and ac to work.<p>Here is a nice web page that talks about how it works: http://www.opamp-electronics.com/tutori ... _03_04.htm .<p>Harrison

I am not trying to fuel the argument on hydrogen from water stuff, but there is a news article that sounds kind of 'similar' to stuff discussed in this thread.<p>News Link: http://news.yahoo.com/news?tmpl=story&u ... gy_chemist<p>Harrison

Take a look at this article: http://www1.electusdistribution.com.au/ ... umloop.pdf . I don't know if it will help you, but it looks interesting.<p>Harrison

Thats not an ISA card. ISA cards have alot more contacts on the edge connector that the card shown above. The gap on the edge connector is also too small to be an ISA edge connector.<p>Harrison<p>[ July 18, 2005: Message edited by: hp ]</p>

Did you connect the other side of the coils on your stepper motor to the pos side of your 9v battery? I would check that first since the ULN2803A looks like it has open collector outputs. This means it switches to ground when active.<p>Take a look at the datasheet (http://www.ucapps.de/midio128/uln2...

Your dvd player doesnt have s-vhs / svideo out? Thats really odd for one that has component out.<p>I would just go with the composite video out on the dvd player if it doesnt have svideo. The reason why is because the component signals are designed for a tv that can support the high resolution. If y...

The MCLR pin will only function as an input in I/O mode.<p>I don't know what your project is, but the input mode has worked for me before.<p>I don't see any problems with using the MCLR pin as an input. The only major problem I see is if you are using ICSP. This would probably cause conflicts if you...

Isn't that a bit expensive? One could buy a picaxe (which is more powerful then the stamp1) for a little over $10.00. One could get one at http://www.phanderson.com/picaxe/picaxe.html .<p>You could 'make' your own stamp 1 at http://www.geocities.com/SiliconValley/Cable/7772 .<p>I am not trying to be...

How fast do you have to control these motors? Would 115kbps from a serial port work? If so you could use the pci to serial port idea noted above. If you really need more bandwidth then use the usb idea in which you would include a usb host controller on your pci card, then connect one of the control...

Ack, must you use the pci bus directly? How about using a commercial pci to serial chipset. That would probably make life alot easier for the microcontroller. Either that or use a usb host controller chipset and use one of the new PIC18s with full speed usb.<p>Harrison
