Thank you very much for the Pro membership.

One question: Is it possible to activate it later if I want to?

Sep 30, 2011. 1:03 PM

Yes, the membership code does not expire and can be activated whenever you are ready.

The deadline is crossed out, does that mean the contest has been extended? If so, what's the new deadline?

Sep 26, 2011. 9:32 AM

mikeasaurus (author) says:

wow that's awesome! But, I can only accept entries that are either SbS Instructables or Photo Instructables. (rule #1).

Sep 27, 2011. 6:46 AMCassisDude98 says:

But why couldn't I enter with the Miter Saw???

Sep 27, 2011. 12:16 PM

mikeasaurus (author) says:

The link you shared was for a project which was posted on the forums, the rules stipulated that projects needed to be in Step-by-Step or Photo Instructable format in order to be eligible for entry in this Challenge.

Here is my entry.

Sep 19, 2011. 9:04 AM

mikeasaurus (author) says:

You need to explain to me how these two entries differ from each other:

http://www.instructables.com/id/KNEX-Mobile-Crane-v-4/
http://www.instructables.com/id/KNEX-Mobile-Crane-Truck-v4/

And how both of these entries are different (new) than the K'nex Mobile Crane Truck you had originally posted (prior to this Challenge start date) which is no longer on your profile.
Unpublishing a project then republishing it for the sake of contest entry is not allowed. Please explain.

Sep 19, 2011. 11:53 PM

xobile001 says:

- I only submitted one entry, not two. The entry I submitted clearly has the word "Truck" in the hyperlink.
- The first link you provided is only a slideshow. The complete instructable is the second link.
- I emphasize again that I am only submitting that one entry; I am not submitting all of my instructables for the contest.

I hope this helps clear it up.

does it have to be pinball machines, ball towers, and coin sorters or can it be something else

Sep 18, 2011. 10:35 AM

mikeasaurus (author) says:

Anything K'nex that is not a gun and does not use elastic (rubber) bands.

"5) The judges reserve the right to disqualify anyone who cheats or engages in unsportsmanlike conduct."

Is making 99 spam posts (that meet all other requirements) unsportsmanlike? :P

Honestly, I think I have something. Is posting an instructable for something I've already posted pictures of allowed?

Sep 18, 2011. 10:11 AMGr3at_Whit3_North_Guy says:

I don't know that rule seems fair so u probably shouldn't do it

Sep 17, 2011. 11:30 AM

mikeasaurus (author) says:

Rules:
6) To be clear, the project MUST be published after the challenge has started to be eligible.

Sep 17, 2011. 9:43 PMBartboy says:

But, if I post a picture of it already, but no instructions, does that affect it?

You have 2 weeks to make something new and awesome!

Sep 17, 2011. 4:40 PM

DJ Radio says:

Lol 2 weeks. You have to work at knex projects for at least a month for it to be good, unless it's small, like a knex game or something.

Sep 17, 2011. 4:48 PM

mikeasaurus (author) says:

If you count the week heads-up prior to the start date that's 3 weeks, and if there's enough commotion of work-in-progress there may be an extension.

Sep 17, 2011. 5:53 AMCassisDude98 says:

I like the prizes... And I might even be able to win with the K'nex ferris wheel kit I won for the WeJustGotBack Challange (of course, I'd have to make something out of it...).
