World Record LEGO Train Layout in Seattle 61
The Dev writes "The Pacific Northwest LEGO train club is attempting to break the world record for the longest LEGO train layout. They are setting up in the Seattle center right now, so you if you are in the area you might want to check it out.

If you find that one to hard to use, you may wish to instead attempt to use RFC #1149 [ietf.org] which has been updated by RFC #2549 [ietf.org] to send IP information using little scrolls and swallows. (Actually, the bird type is unspecified and is left to the implementation.) Unfortunately, the latter types do not work under Linux implementations, since they have had troubles getting the penguins to fly.

Since the word doesn't exist in the English language, I think its fair to pluralize it any way we choose.
Language derives from those that use the words. It isn't decreed first, and enforced later.
Also, about being pedantic. It can mean either rigid and formal, as in a proof (I assume you mean it that way) or as being overly concerned with minutiae (which is the way you sound). Or, maybe you we're just trolling and I bit.

Short answer: I don't have control over how the piston is constructed.
Long answer: Here's the deal. I'm trying to stay completely Lego here, nothing you can't go to Toys 'R' Us and buy. The pneumatic sets(at least the modern ones) have a double input plunger and a single output pump. In my experiences, once there is pressure in the lines, you don't really lose it, the pneumatic nail guns don't keep the air pressure, they release it so the spring can pull the piston back. The Lego pneumatic cylinders, once charged, will keep their charge unless you break the circuit fully.
I wish
Basically, I don't lose all that much pressure when I fire and retract. It's the slow pumping that's killing me. The only way I have to get the charging pump repeatedly up and down is with a spirograph type action, a long piece tied to a gear at one end and the top of the pump at the other. Unfortunately this only moves the pump the diameter of the gear each rotation, so it's not a full stroke. I can't use a large gear or it puts too much lateral pressure on the pump and bends it instead of pulling it straight down. Grr, it takes forever(on the order of 15 minutes) to charge primarially, but sucessive charge times are much faster(3 minutes or so)
I'm going to switch to a different type of plunger, one with just a single input and figure out a way of re-directing the airflow to make it both suck and blow at different times, the single pin plunger is an older model and has a larger diameter piston head so it'll hit harder.
Wish me luck.

On the other hand, if they implemented an IP-over-Lego-Train protocol, and had the trains transfer packets between controlling computers, they'd have a really cool setup! (Trains that tell the controllers what to do! Just like in Real Life! :)
It'd be cool if they provided open extensions, though. Can you imagine a decent train service in the US?

Info about Automation/Control of Lego Trains (Score:5)
Finally something I can comment on with some degree of expertise! :)
Someone mentioned Mindstorms control of the layout. First off, Lego 9V train systems run off of a single power source controlled by what appears to be a crude stepped power supply (the 4548 Regulator). DC is fed into the entire track, and the Train Motor pack picks up that DC and drives its wheels. You can put as many packs as you like on the same track, but they'll all go forward and backwards at the same time because the entire track is electrified.
A Mindstorms RCX 1.0 could be used to power up these tracks in place of the 4548 and execute control on one of its motor ports. The other two ports could be used to drive cranes, scenery, gates etc or another isolated track system. That's kinda boring though.
The first option is to use what's called cab/block control. Fans of model trains (HO etc) will recognize this as powering on sections of track from a cab, or one power supply/regulator. So any given section of track could be fed separately by Cab A or Cab B, effectively meaning two motor packs are independently. As a train approachs a section of track, you power it up with the given Cab you are controlling, and unpower the section you're coming off of. But this means only one motor pack can be travelling within that section.
If you wanted to use Mindstorms to automate here, there's probably some cool application of using one motor to do the switching of block sections, and one output to power the track.
Another option is to isolate the motor pack from the track and power it solely using an onboard RCX. This has been tried by Matthew Bates and others. However, the draw of the motor pack soon drains the 1.0/1.5 RCX's six AA's. This would be one way to have a "ghost train" drive by itself without any connection to the 4548 powered track. You need to hack the motor to remove the pickups from the metal wheels.
A third, and much more elegant option is inband signalling, or DCC . Model train fans have long enjoyed the NMRA DCC (Digital Cab Control) standard, which sends a coded pulsewidth modulation signal along a powered common track. DCC motorpacks pick up power and pick up the control signal. When they get a command intended for itself, it powers the wheels. In effect, the track becomes a common bus where power and signal come from but the operation of the motors is dependent on the commands issued in the signal. What's also cool is that switches, scenery, etc can be latched into the track bus and controlled with automation or remotely.
Attempts have been made to put DCC into Lego trains-some experiments to isolate the track pickups/motors, then solder in a DCC decoder/controller into the pack have been successful. However, problems with voltage (9V vs normal 12V model train power) have hampered this. The cost is also hard to deal with-you're looking at least $400USD, when most people have tons of spare 4548's from trainsets.
There's also a lot of other cool stuff you can do with Mindstorms-using the IR, you can have a proximity to set something off (like gates on a road) and play a warning bell when a train nears. It's a $110USD track crossing, but... :)

Creative Juices Flowing...must design...can't stop (Score:4)
For some reason I looked back through the archive of Lego topics on
Basic idea. Put a motor on the plunger which charges a compressed air tank so it charges continually. Have two lines running from the tank to the firing plunger controlled through a SPDT switch, when air is put in at the bottom of the firing plunger, it shoots out and knocks the brick down the barrel, when I throw it the other direction, it will allow the compressed air to flow into the upper input on the firing plunger and retract it, allowing another brick to fall into the firing chamber from the clip. And I can even build the switch into the housing so it looks like a trigger.
The only real problem I see is getting the air chamber compressed to the point where there is a decent velocity imparted to the brick when the plunger strikes it. Those motors don't have near the amount of power the old Robotix building set motors did. I'll have to build gear ratios to allow the mechanism to push the compressing plunger down once there is a fair amount of compressed air in the tank already. Of course my upper limit is the working pressure in the rubber lines, I can make the gear ratio something ungodly and put tons and tons of pressure into the chamber, it may take forever to re-pressurize after firing, but that's the only way I can see to get decent velocity out of the firing plunger.
Now I'm going home and build this stupid thing, my kids will love it. I'll post the design when I get it completed.
