The 200 uses only springs to connect things(you bend the spring over and shove a (or more) wires in between the coils). This means that all the componets must be layed out on the board. And stay thare.
The 300 makes use of a breadboard, this means that for each project you can lay out the componets as closly as you want. What you don't see in the pic of the 300 is the bag of resistors, caps, leds, wires, IC's diods, etc. that comes with it. The ironic thing is the 200 wastes space because you have to deal with the parts that your current project doesn't need. OTOH I have a habbit of chewing on a wire or LED when I'm podnering something. (I always get my daily recomended value of GaN+SiC:) +5 CoolPoints if you know what color that is!)
Bottom line:
int age=n
int product=0
if {age=
then product=200;
eles product=300;
}
return happy customer;
I do own the 200, it nice but I would prefer the 300. It has a breadboard and thoes are ALWAYS useful for messing around with all kind of circuts that you don't find in the manual.
See this, You use it to plug in electronic componates without having to solder or wirewrap them. The holes are electricaly connected in 5-hole patterns under the plastic face.
I made a comment yesterday about mirroring a very large file and I would like to reinterate it here with some extra stuff.

I can bet you that M$ didn't do this to be a good citizen. If this passed, they would have an ASS load of code to redo to incorperate the new 'standards'.

Reverse engenere the codec and write your own player for linux. Didn't some kid do something like this so he could watch DVDs on his linux box?
I know I may be talking out of my ass on this becaues I have no idea how to reverse engenere anything right now and there could be an issue with the DMCA. But, one can learn how to do this and FUCK the DMCA.
I like your idea. If I understand it correctly, you want to make a standard positive displacement pump, just replacing the piston with a ferrofluid ball. Or, you want to squeeze the ballon at the end of the stroke and have it move back down the pipe to re-expand and push more water forward. Either way I can see how this could work. BTW I remember a picture of an anchant water lifting device that used a chain with ballons attached evenly along it's length. Then it was threaded through sever vertical lengths of bamboo, then pulled over a wheel cut with recesses at appropriate places(like a common chain pulley of today). Someone then turned the wheel at the top and the ballons where polled up the tubes and trapped a quantify of water above them. Pardon my sidetrack.
On the issue of controlling the solenoids, I would suggest you use logic gates run by a digital watch clock signal. Because most circuits allow you to set the time by sending the raw clock signal past the dividers (that slow it down) and straight into the counters. This has the effect of speeding up the clock and the digits change very fast.
(Remember when McGuyver was locked into a hazederous waste incinerator and the hot wast was about to pour into the chamber and the door had a time lock on it. He opened the back of the timer (not that it would have been accessible from the inside of the door) and shorted out the circuit (specific the divider circuit) and the timer started to run at like 1000 seconds per second. The door opened early and he an his female companions got out before the hazardous green sludge started to pore in. They also remembered to grab the folder containing the secret documents hidden behind a pipe to lure him inside the chamber). {rant}I am SOOOOOOO pissed that it was canceled. I learned so much clool stuff from that show.{/rant}
Take a look at this article, and search around for "half adders" and "full adders". Those are the kind of circuits you will be dealing with. Also, you could use a chain of flip-flops and capacitors attached to the coils to carry the signal down the length of the pipe.
I really like your idea and if you need additional advice or ideas, e-mail me. I'm not an expert on magnets or electronics, just a hobbiest I guess.:)
I saw a program on TV a while ago that said they should NOT have tried to steer the ship away from the iceburg, but go all back full and plow right into it. If they did, the bow would have been distroyed, but the burg couldn't have ripped an opening down the whole side of the ship. This could have been a moot point sence the tops of the 'watertight' bulkheads whern't so.

The RIAA issued a challenge to the world when they asked challenged people to crack the SDMI. Guess what, Felton did and it's tough nuts for the RIAA, they started it.
It's like this:
Some states have laws that say you can shoot dead any intruder that invades your house or propriety. That's fine for dealing with some thief looking to pinch your sterio or PC. You can call that person an intruder because you didn't invite him/her in. But what if you did invite someone in to your house? Can you shoot them? Hell no, You invited them, you started it.
As far as I'm concerned, the RIAA invited people like Felton into thair house and handed him the expensive silverware and is now threating to shoot him if he leaves.
It's as if the school bully called you out, you pounded him, then he calls the principal on you.
I do agree that EVERY mailing list MUST be double opt-in. To me this sounds like common sense, but I'm not a $grabbing bastard that will do any thing for an extra buck.
The thing that really pisses me off is the fact that the companies can sell my address to hundreds of others without my consent. This is what I think happens all the time:
Sone jerk signs me up for spam from company A
I get spam from A with a 'remove' link in it
I click 'remove' and no more crap from company A
Company A sells my address to company B C D E F... and they probably earn more money from this than they would have earned from my buying something from THEM
I now get 5x the spam F---!
GOTO 2
I think this reselling of names can be worse than no double opt-in. I know the big companies won't allow this (by buying politicians and lobbyists) on the grounds that thair ill-gotten lists are thair property and can do with it what they wish. I know it would be hard to keep a list of the companies that do this, but I think MAPS should consider upgrading thair service to include several lists that offer variable amounts of protection to ISP admins. Like one list with KNOWN spamers, one with ALLEGED smamers, one with PROVED non-spamers, and one that would be managed by users, kind of like how moderation and meta-moderation works here on/.
I'v seen a few comments (mostly here) that this is the film to gleam off of one of thoes evil file sharing networks. I wonder how many people will do this and if the networks can keep up with the demand? Could this grind the net down to a crawl like all thoes viruses like Nimda*? I doubt it, mostly because I don't know all that much about the way packets are shuttled around the globe.
I guess my question is how many people will try to download it as soon as someone rips it, or will we all be law-abiding and get it from a store? Also, do you think this will slow down internet access allover the world and cause routers to spontaneously combust? Oh wait, I forgot that no one here would ever illegally download copyrighted material.;)
*Off topic, but when you herd of the Nimda, did anyone else immediately remember The Secret of Nimh? I love that movie!
Say a company, oh let's call them "Macrohard", makes a computer and wanting to round things out, writes some operating software to make the whole thing work. Let's also say that the computer costs $1000(for the hardware) and because they had to pay some geeks to with the OS, they charge $200 for that. People love it and gladly shell out $1200 for thair product.
Now you need an OS if you want your computer to be more useful than a door stop, so Macrohard sells the OS and PC as a package deal ($1200 bucks).
Everyone loves this deal except for one guy who loves the flightless emus and is named Cledus. He wants better software and his favorite color is not blue! So Cledus writes some code and turns it into a kick-ass OS and people love it AND he gives it away for free. He calls his OS... Cledix (cool name). Cledix becomes very popular with other people who love emus, thus bring in a whole new market for Macrohard's products.
So now Macrohard is, instead of giving him a pail of cash for giving them all this new bisness, they threaten to sick the lawyers on poor Cledus. Macrohard says that they own the copyrights on all the functions and calls that allow the OS to talk to the hardware, and they do, but that's not the point. "The point is", quoth the founder of Macrohard, Mr. Law Fence, "Cledix is a terrible threat to our company, it alters the way our hardware preforms [forgetting to mention that it works better running Cledix!], makes people think that we endorse this 'Cledus dude' and his OS [also forgetting to say that the PCs are not shipped with Cledix and that you need to spend some extra time to install the other OS]". But "most of all", says Fence, "it cuts into our profits, and we will not tolerate [fair] competition! [again forgetting that Cledus has increased thair profits by drawing in a whole new sector of PC consumers] Oh, I almost forgot to remind you that Macrohard does't sell it's PC ($1000) separately with it's software ($200). This means that you HAVE to pay for a copy of the Doors operating system when you buy a computer! The upshot of all this it that Macrohard does NOT lose money, thaie brand name is NOT diluted because if you are using Cledix it is quite obvious, you had to install it yourself or coax a geek out of the server room with promises of highly caffeinated soda to do it for you. They can easily ignore the issue of tech support, if they want to, by reminding users that changing the OS voids the warranty.
I hope the above gave you something to think about. My bet is that the Mindstorms people will talk/beat some sense into the corporate goons and get them to back off. They should be praising people like Dave Brum and Markus Noga!
The way I see it is that they'll sell more P4s if people can use the cheeper DDR RAM. This is the main reason I don't have one. I reacently upgraded the guts of my old computer from a 600Mhz Athalon w/SDRAM to a 1.2 Ghz Athalon + DDR. What I was really wanting was the DDR RAM and it was worth it. I would have gone with a P4, but I'm not going to spend all that extra $ on memory that won't be around for long. Intel lost my biz when they hooked up with RD RAM.
On another note: "They are not licensed to sell products that are compatible with the Pentium 4," Intel spokesman Chuck Mulloy said.
Sense when can they do this? If I want to make and sell intake manifolds I suer hope there is'nt some fucked up law that forces me to get ford's premission first.

This is a super cool thing to build. And they can be very powerfull. I built a couple of them out of film canisters, straws, and hot glue. One blew the shit out of its self, it was cool!

BTW: if you're considering downloading thoes files, don't waste you bandwith. Think Hitler(-the military power) crossed with Rush Limbaugh.
This could turn out to be a major legal problem for Phoenix. We all know what bad tings can happen to your pc if you flash the BIOS and something goes wrong? You guessed it, $1000 door stop. How many times have your internet connection died when you're in the middle of a sweet download? Ok, I'm sure the data won't be "streamed" to the chip, but still what if something went wrong? You wake up in the morning with a dead system. (I smell small clames court.)
The other problem I have with this is that, as I understand it, all requests and call go through the BIOS. I'm talking about file requests.
>Phoenix: Hello, our systems indicate that you have a copy of Chicken Run on your computer. We CRC'd it and that matches up with the CRC of an illegal DivX rip of that DVD.

How about some Australian company start to make DVD players that have DeCSS built in to decode any region disk on the fly? A'm quite sure that with a deticated chip it would be fast enough. And the last time I checked the DMCA was a US law.
