Flashing Light Indicator?
So I decided to test eh "flashing light indicator" mechanism and found that it didn't work. Could anyone else confirm whether or not it works for them? We wouldn't want a broken mechanism on the page :\
 * This "flashing light indicator" is very crude mechanism, so it will flash only few times. If you want make something smoother, you should connect pressure plate to RS NOR gate (don't forget to make reset button), then make a 5-clock (or any other clock, but not Rapid Pulser), then connect output of clock and output of RS NOR to NAND gate, which will be connected to input of torch.
 * It was only meant to flash a few times, then stop, to negate the need for an off switch. Crude, but imho effective.

Canons and Boats
My brother said when he launches a boat from his cannon it will drop multiple sticks and pieces of wood (way more than normal). Can someone confirm this? Matti-Koopa 14:53, 3 November 2010 (UTC)

Is it just me or have they changed TNT so that it is not swept away by water thus making canons much harder to create? Zinob 19:03, 9 June 2011 (UTC)

Pictures
I feel that pictures of the mechanisms and how they work would be extremely helpful to anyone first learning about these --Magitrek 15:02, 13 December 2010 (CST)

Light Sensors
Mentioned light sensors and gave a link. Needs to be explained more thoroughly. Maybe mention light sensors on flower and mushroom wiki pages? Bumber 03:32, 26 March 2011 (UTC)
 * Flower and mushroom pages now mention light sensors and link to this page. Mechanisms page still needs a discription instead of just a link to a forum thread. Bumber 05:26, 8 April 2011 (UTC)

Retractable staircase
Should the retractable staircase shown in the piston demo be included? -[user:kingleonidas1234] 6:45 (MT)

Mod related tutorial removal
I think we should remove everything concerning mod pistons. Agree? | TheKax |  Talk   10:27, 8 July 2011 (UTC)
 * I like the idea but I don't think it's drastic enough. Here's another option, we break this page into several pages where the content is specialized rather than a wide-ranging dump of partially completed (cough*abandonded*cough) tutorials. If mechanisms is a subsection of tutorials, what's the point of this page?Qcdynamics 14:39, 27 September 2011 (UTC)
 * I agree, the attached video is gone, too. it does not concern this article any longer. Turboplant 23:13, 18 November 2011 (UTC)

Cannon Range Equation
Ok, so before I give you the numbers, let me first explain how I went about this. I used my Ramses Cannon to test this (link provided so you can see the details of the platform). I tested range at elevations of .5 blocks, 1 block, and 1.5 blocks, as I considered these the practical range of elevations. I used charges from 1-7 tnt for each elevation. I recorded the distance for each shot from each pairing of elevation and charge size. I then took that data and using magic created the following equation.

EQUATION

f(x, w) = 13.0539 + cos(0.35123932 - x)/(32.091557 - 15.533575/cos(18.448326*w - x) - 47.684593*x) + 11.635796*w*cos(0.35123932 - x) - 3.8064015*x*cos(18.448326*w - x) - 12.089317*cos(18.448326*w - x) - 11.635796*x

STATISTICS:

r^2: 0.997904

Maximum error: 3.374008

Minimum error: 3.8147^-6

This is more for testing purposes than actual use in combat (my server's battles are too fast for such nonsense), as unless you've got an application built to do so (I made a quick C++ for it), plugging in the numbers is a bit tedious. I feel like a better equation could potentially be derived if more data is used, but I'm pressed for time. If someone would want to help me make a better equation, I suggest using the Ramses in a no-lag environment and measuring elevations of 0, 2, 2.5, and 3 with 1-7 tnt charges. I do, however, not see the point in ever actually equipping a cannon with elevations at the extremes; they are useful in only a handful of situations in battle (and can be accomplished by specialized equipment much easier). Please tell me what you think. My goal for the equation is to be included on the actual page after validation and such by everyone. Thanks for reading. Cactus Master 01:47, 22 November 2011 (UTC)
