I just tried searching on google for 'Electronics World Magazine' and got the link http://www.electronicsworld.co.uk/elect ... efault.asp which still works.
The news stand may have stopped ordering that magazine due to lack of interest, etc.

Here is an AppNote for controlling DC motors with an h-bridge that is directly controlled and managed by a PIC16F684. The PIC16F684 has an advanced PWM module which can output PWM signals to directly control an hbridge. Note that this specific PIC directly controls the mosfet drive transistors in th...

They probably picked this forum because it comes up on search engines and is relatively popular. I did take a look at seeing what kind of security features are already in place (image validate, email verification). Apparently both are turned on, so therefore these bots must be amazing and are using ...

Some PICs are designed to be motor controll PICs, which means they have the ability to use one or two hardware PWM generators to generate 4 signals for an h-bridge. The PIC16F87x series chips have 2 hardware pwm channels. Using two in theory would give you 4, but it may not be the 4 that you want (i...

This is probably not the answer you are looking for, but is there any reason why you can't use the free student version? The only major problem with the student version is that it generates less efficent and larger binary images after 60 days. The commerical version seems extemely expensive (as in $...

Hello again, I like that little Prallelex heat sensor, but i am wondering how it works at other temperatures, like say -20 degrees F ? Does it still work at that temp or go south? I haven't used the module before, but you could always email Parallax support or post on their forums asking for inform...

Parallax has a nice cheap motion sensor (less than $8 bucks). http://www.parallax.com/detail.asp?product_id=555-28027 Heres a small review on it: http://www.scary-terry.com/itw/pirsensor/pirsensor.htm . I would highly recommend buying it from Parallax, especially since their shipping is around 69 ce...

Digital TV allows much more data to be encoded in the signal (including much higher resolution) then conventional analog broadcast. When the color NTSC specification was devised, it was meant to be compatiable with older technologies, such as b/w tv. This signal can only carry a resolution of less t...

Just a note: Modern hard drive controller boards are loaded with data that is unique to the drive's specific hardware specs. This includes bad sectors, timing, etc. This may seem kind of odd, but even a perfect hard drive has bad sectors. These are generally found at the manufacturing line and loade...

Try looking at Carnegie Mellon University's Robotics Institute at: http://www.ri.cmu.edu/ . It seems like they offer undergraduate minors and graduate degrees in robotics. I have seen many robotics related things come out of CMU. You may have heard of the CMU CAM, which was developed by the computer...

The siteplayer uses a system called 'site objects' that are really just specialized tags that follow the format ^tag^. The tags are replaced by data in specific memory locations in the siteplayer module's ram. You can specify your own tags and memory types and locations. By doing so, you can utilize...

I have used the siteplayer webserver module from Netmedia ( http://www.siteplayer.com/main_content.htm ). The module is very easy to use and generally requires a microcontroller to interface with it. If all you need to do is send serial strings via a web interface or do some minor I/O (on/off), then...

Look up Windows Media Encoder on microsoft's website. It makes broadcasting streams really easy. You can stream videos, capture devices, audio, etc. You can almost do a web broadcast using it. It does use alot of CPU and RAM though. It compreses the video with wmv streaming, which is pretty efficent...

Actually, Intel's performance per dollar is somewhat better then AMD's right now. Take a look at intel's midline dual cores and you will notice that they are pretty cheap. Couple that with a ASUS or ABIT mb and you have a pretty good and cheap system. But I have to admit that AMD had better performa...
