Ideas for a sun for my model solar system?

I've just built a big model solar system for use in class, and i'm trying to think of what to use for the sun. The planets are roughly the right sort of varying sizes, and Jupiter is ten inches in diameter, which means the sun needs to be pretty big. I'm thinking of a big hemisphere to cover up the base, like half a big plastic ball, but I'm not sure what to use as the size lets out most plastic balls that i've seen. All suggestions welcome!

rating system

It just occurred to me that Instructable ratings are based in part on the necessity to return to the Instructable to review instructions. Instructables that have steps that are intuitive and/or easy to remember may not get any ratings. In other words good ratings equal Instructable complicated enough to require several visits. That leaves number of views. With a nude or two you could probably get a lot of visitors and a very high rating as well. ;-(

No Help System

Does a REAL online help system exist on this website?  I mean as on any real application program you may be familiar with.  Does it exist and if not why not?  This site is mature enough that it should have a resource which anybody can go to to answer the question " How should work?" or "Does exist?" Up until now the only semblance to "HELP" I have seen is a forum where we all talk amongst ourselves and maybe somebody may throw in a nugget of real fact or wisdom.  But nothing where I can go to get any authoritative information. Why should I have to wait (days/weeks) for a reply from the general hoipaloi instead of getting a (relatively) immediate answer to a simple question? In fact I have been a member for 14 months now and just today is the first mention of the word "staff" have I found.  Staff??  No one in the forum is identified as "staff"! It seems as though no one is running the place. WTF?  Why no real HELP!

Gravity Feed Central Heating 22mmx2 28mmx2? Answered

Hi All, mate of ours drained his heating as he was extending a kitchen rad, long story short when he came to fill it up again no flow from the gravity CH tank in the loft down to the boiler, tried sucking on the rads to get flow cracked pipes open and all sorts, he knows there is an issue with air locks in the system as he has them a couple of times, he had a power flush about 5 months ago to eliminate sludge so shouldn't be that, looking at the lay out of the house it looks like the pipework is an issue due to floor levels being all over up and down! so my question is would installing a second pump at the side of the header tank in the loft force water through and back up the boiler escape be a good idea for this on going problem, he's brassy so new install or referb of the system is a long way away, poor blokes house is freezing, thanks in advance for any reply and suggestions before I go round tonight to have another go, Cheers Matt

Star Rating System Implemented

Instructables can now be rated on a 5-star rating scale. So instead of saying that you like an Instructable, you can now say just how much you like it! Some fancy mathematical formulas were used to convert the previous ratings to the new scale, providing the scores that you see now. These formulas will be getting tweaked as we get some kinks out of the system and fine tune the results, but all of the new ratings will be saved for more accurate results in the future. So for now, go out and use the stars to more accurately rate new and older Instructables! More ratings will help fine tune future searches and encourage more people to post better Instructables.

Rating system

I'd just like to say two things in relation to the new 'view ratings' feature: Firstly, while you can now see who rated your project low, this doesn't mean said person hates you.  They probably don't even remember doing it.  Sure, mention it to them (I myself have sent a few choice PMs), but don't dwell on it.  You have probably done it at some point, and would probably rather forget about it.  See this as a chance to correct your mistakes and give older projects a fair rating if you want. Having said this, I would hate to see people bullied into giving 5* ratings to everything for fear that they may get picked up on the odd 3.5* etc.  As long as you express your honest opinion. But seriously, ratings on this site are typically ridiculously skewed anyway, so I wouldn't get too hung up over it.  Most people don't care about ratings at all.

I was thinking that it would be a web browser add on that would add the functionality. and all of the comments would be decentralized and stored on the users of the comment program computers. What programming languages would be needed to complete this task?   How long do you think something like this would take to code? Please tell me you thoughts in the comments!

Designing a different / customized kind of computer system?

I've read about how when you Install the windows OS onto a usb stick It's unique to that computer (b/c of specific drivers, specs, hardware etc... and yes, It Is possible with some tweaking, don't spout out propaganda you're fed from Microsoft and apple). I'd like to know what it would take to design a generic computer that all you would have to do is plug in your personal drive and your OS (whichever it may be) and files are programs all there ready for use. And also be made in such a way that if the 'terminal' were duplicated part for part, no matter which one your drive was plugged Into It, would work the same. I'm thinking of designing a kind of system like this- drawing on elements from sci-fi (which is obversely based on the real world) In Stargate Atlantis and Battlestar Galactica (reimagined version). In Stargate Atlantis, Atlantis Is a cIty-shIp that has In Its Infrastructure the hardware, database, and OS, which is accessible from the hundreds of terminals throughout; each one is like a separate pc but are all connected to the database and processing power of the city as a whole. In a similar way, In Battlestar Galactic, the Galactica class Battlestar has a closed network which they rely on Instead of wireless to prevent cyber-attacks from the cylons... but the only advantage I care about Is that data transfer Is much faster via wires, and fiber optic cable even more so. With the amount of products and parts available on the market today, budget is the only limiting factor. I know many people are programmed to say, "It’s not possible" or immediately shoot it down by saying how hard it would be, and that I should just buy a computer and be happy. But I am not just a consumer, I’m an artist, a designer, I’m not going to let other people call the shots just so they get a profit. Now I know Linux has the sort of open source availability I like, but I’m not too familiar with It and I’d like the project to be user friendly as well as geek friendly If the user so chooses (like an optimized combination of apple, Microsoft, and Linux). I will no doubt read around at the library and online, but I wanted to hear from people who already have experience and know what I’d be better off learning and what I’d be better off skipping altogether.
