This is not complicated at all.\n\nLM317 is an IC device with only 3 terminals.  Here's an URL to the diagram:\n\nhttp://www.national.com/pf/LM/LM317.html\n\nYou willneed a transformer, full bridge rectification circuit, and filters.   You need to spec the transformer so that the output of the rectifier/filter is at 15V DC at full load.  Notice that under no load, the ouput will be at sqrt(2) * (ac voltage).  Under full load, it should drop to the RMS value of the outout.  (basically means to use the 15V transformer)\n\nThe filter capacitor must be large enough so that ripple will be at minimum at the full load.  4700microF or larger should be sufficient.\n\nRemember to heat-sink the 317, as it will get quite warm at full load.

There is indeed one in development that a researcher used on himself to test out embedded technologies.  There are number of news articles about it (well not really news since it was 1998)\n\nSee sources for links

you can try your local library. i'm not sure if stores like best buy or circuit city rents out computers.

How do I set up lab of 40 computers on 2 campuses located 5km apart?This is for a school project?\nEach lab should have 40 computers connected to a network. \n\nFirst I'm not a professional but since at the time I started this answer no one replied I'll offer what info I know.\n\n\nQ: Are these actually full functional computers like regular desktops or laptops or are they merely dummy terminals which send their requests through the main server ?\n\nIf they are terminals (dummies) then route them all through the main server which handles all the processing.\n\nIf they are individual computers then they each handle their own processing and only need server (and likely internet) access.\nDepending on your budget and preference, but you'll likely use ethernet to hardwire each desktop computer into the local network by using routers and or switches.\n\nA router is a device that can split one internet and or server feed [data to and from ] into many different computers. (Just like a wireless router except a normal router has wires).\nThe cable is called ethernet cable and it plugs into your nic card, aka network interface card.\n\nAllowing the computers from one lab to another lab for communications should be done over the internet.\n\nIf security and access are issues then you may want to route all lab computers to go through the main server which then contacts the other main server.\nThe servers can be setup to only allow access from certain machines/IP's, etc.\nThere are many software and hardware (firewalls for example) settings that help do this.\n\nAllowing students to access view of grades [or their projects] is handled easily enough by storing the grades/student info in a database. If you want students to only be able to view their own grades/records then give each student a password and login ID. If you allow any student to view any other student's info then they all can have the same login info/password.\n\nIf you want to allow students to be able to access this information via the net from any computer then it would fairly easy to make a website/web page using MYSQL and PHP to do this.\n\nYour PHP code would control what access the students have, if that's too difficult for you to learn how to do, or you don't have the budget to pay someone to do that (it's not very hard) then you could simply have separate databases one that only stores the 'viewable' grade for the students and not the actual grades used for the teachers. Then disallow student access.\n \nAs you can see there are many solutions to each problem so you really should think about this in more detail before you commit to any one solution.\n\nOne of the best and most common and inexpensive databases to use is MYSQL.\n\nSharing of work files is solved because you're on the local and remote network already.\n\nYou only really need to choose what means of file transfer you'll use.\nWhich software product or to use a built in method, depending on OS of choice.\n\n\nFor example Mac OS X has ftp, sftp SSH, and probably other means built in for file transferring, or remote login/control built in.\nAlso, OS X comes with the ability to be a web server via Apache, one of the most of the most widely used web serving software around.\n\nPersonally I'd stay away from running Windows or Linux. Windows because it's not very secure and Linux because it isn't very user friendly.\nMac OS X is built upon Unix which means it's completely reliable and professional grade. The Mac GUI (Graphic User Interface) is very user friendly while running Unix under the hood.\n\nIt doesn't sound like students should be able to access other students projects at all, or at least directly because this could lead to problems.\n(malicious students doing harm to other student projects, students copying/cheating from other students projects,etc.)\n\nOS X is a multiuser operating system where each user can setup his/her own accounts

Digital trainers are great tool for students and hobbyists to experiment with integrated circuits. \nThe best way to learn about these types of devices is to build various types of circuits and observe results. \nThe digital trainer makes it possible to easily wire and substitute gates, timers and operational amplifiers and build functional circuits that are only limited by the imagination. \nThey are a solid educational tool and great fun at the same time.\nThey all include:\nVarious power supplies\nBreadboard for ease of wiring\nCommon I'C's\nSupport components such as Resistors, Capacitors, Diodes, etc,\nInstrumentation, such as volt, ohm, and ammeters.\nSchematics and instructions for Experiments.

I think they just held Cebit2006 about a month ago (in Germany i guess, but i forgot).  Try googling and search for Cebit.  That is the biggest electronic and computer exhibition.
