1.  If you want an interesting project, try http://www.halfbakery.com/category/Computer Be aware that many of the suggestions there are either impractical, difficult, or not software-related.\n\n2.  Make a game.\n\n3.  If you want to make something new that people will use, ask if anyone has any ideas in the alt.comp.freeware newsgroup (unless you plan to charge) or look through the archives for requests for programs which were unfulfilled.

Buy an electronics lab from Radio Shack and build a few projects. I was bought one when I was 11 (about 26 years ago) and haven't looked back. The best way to learn is with practice and its never too late.

what kind of project?, maybe i could help you, let me know...

You have the classic case of "a solution looking for a problem". That's always a little frustrating. It just sounds like you don't have enough materials there. If you buy another small electronics kit, then you can have more things to play with.\nOne thing that comes to mind is an alarm clock. Hook up the led and buzzer to an existing alarm clock and make it sound in unison.\nAnother thing could be to create an "phone ringing alert". When you land line rings, have your contraption light up and  buzz, so that you might know that the phone is ringing if you can't find it.\nIf you add a remote trigger, you can make a remote control finder. The tricky part might be to attach it to the remote.\nOh, another great idea is to make a timer for the kitchen. That's always useful. You can somehow integrate the machine into something cool, like a darth vader pez or something, and add a timer you can buy at Wal-Mart for 5 bucks.\nAlso you could make a marbles game kind of like Pachinko: a long board with slots and one end, and you let a ball fall from the other end (like a slide) and the ball has to fall at a certain slot and it makes the buzzer go off.\nVisit site below for ideas

Check out these sites. They've a lot of links to electronics tutorial websites.\n\nhttp://www.epanorama.net/links/basics.html\nhttp://dmoz.org/Science/Technology/Electronics/Tutorials/

I just helped my daughter with her science project. We made an electromagnet. Very easy to build and you can get buzzers, lights, and battery holders a your nearest hobby Lobby. you can also get toggle switches at the local hardware store. Mount it all on a nice piece of wood and your in business. by the way, my daughter took home first place!

Think of something you dislike doing or find boring or time consuming.\n\nSo for me a sock sorter would be good.\nHow about a uv light to sanitize restrooms.\nHow about a remote to mute the booming music from other cars.\nHere is something totally useless, How about something you can add to salt to change it's color. Make it designer to match the table setting or to add a bit of color to the top of a dish.

The best project will be one that has some interest to the 8th grader. So my granddaughter likes animals. But my youngest boy likes photography. So a pinhole camera would bore my granddaughter but would have caught the interest of my son.\n\nThat being said... Here's an easy one. Go to a store and find some cheap analog clocks (clocks with hands) that run on a single AA battery. Then go to Radio Shack and get some battery holders and some "aligator clip leads" -- short wires with clips on either side. And get a bunch of different brand batteries of different sizes (if you are trying to get by simply, use only AA batteries and then you just need the clocks and the batteries).\n\nTake off the battery covers and hook up the battery holders to the clocks with the clipleads (unless you are only using AA batteries). Then put batteries in and see how long it takes for the clocks to run down. This may take a long time. If you are short on time, try this. Get a flashlight bulb at radio shack and put it across the battery with the clock. So this way the battery is running the clock and the flashlight bulb at the same time. Note the time on the the clock and check it every day to see when the clock stops. You can graph the results easily.\n\nQuestions (form a hypothesis and answer one or more of these):\nWhat lasts longer, a AA, a C, or a D battery?\nWhat brand of battery lasts longer?\nWhat lasts longer, a standard carbon-zinc battery or an alkaline battery? What is the cost difference per unit? Per run time?\n\nA little research on the internet about how batteries are built, and the different technologies (carbon-zinc, alkaline, nicad, NiMh, lithium, lead-acid) and you have a great project.

Check local thrift stores and consignment shops.\nTalk with those who deal in electronics.  I've discovered many useful computer systems (Gateway 2000s', PowerMacs) for around $20-$50 each.  Even bought a few.  They work great with old software from ebay with the kids' ages you have.

This website is wonderful. I did my first project with the PIC chip after reading it. It makes it real easy and contains the MPlab assemblies. My advice is that you should learn a little first and then start trying it.\n\nhttp://www.rentron.com/PicBasic1.htm

there are micro chips you can get that you can use to make a ide 2 usb cable but then you still have to build a power supply for 12 and 5 volt supply and you would be better off getting the ide 2 usb then trying to do micro circuits and then the static and making the circuit board basically you almost need to go to devry or MIT to learn how to do it so make it easy on yourself and buy it

I'd try eBay first!\n\nYou can check out Completed Auctions on any item...to get an Idea of the Price Range for the Electronic Components you're looking for!\n\nLocally, use the Yellow Pages.
