Working K'nex Clock

This design keeps accurate time using a geared-down K'nex electric motor. Numerous closely-meshed gears provide smooth movement for the hands of the clock.

should it be reallly wobily at this point?

[Lowney]

Well it's not the sturdiest thing in the world at this point; it should be wobbly but not to the point where if you let go it would collapse.

[lemonpickle]

huuuhhhhhhhh what knex piece do u not have

[jingo69]

I have been waiting for the day, someone made a K'nex clock this is JUST AMAZING!

[Lowney]

Thanks, I'm not the original creator of this, I simply brought it to instructables to give it the views it deserves :)
Also, I would greatly appreciate it if you check out my latest forum topic :D

[jingo69]

I will =D

[killersir751]

You buzzkill.
I've wanted to make a k'nex clock for ages and now i finally find one, and it uses too many pieces and some pieces I've not even heard of.

[Kruegem]

awsome once i get enough nex im building it

[verypoopy]

does it acully work???

[Lowney]

yes

[H1T4TCH1]

finally, A KNEX CLOCK!

[CrazyCHRIS!!]

what is the website this was on, they have lots of other projects too

[Lowney]

Google "Scott's knex design Gallery"
It's one of the first ones

[CrazyCHRIS!!]

thats it thanks

[Knexwizard]

do you have to use that exact moter?

[The One and Only]

Apparently the motor used in this ible has an rpm of 30. A battery powered one (red battery pack, clear engine) has an rpm of 32 rpm, so there isn't too much in it.

[Knexwizard]

so you can use the other moters?

[The One and Only]

Um not really no, as that one little difference will be enough to make this clock useless.

[Schober]

The motor used in this Instructable has both an high rpm but also a fairly high torque. When geared down from the worm gear the speed may decrease greatly but the torque goes through the roof and is quite difficult to exceed with K'nex. On the other hand the battery powered motors have both a low rpm and a low torque. When the resistance exceeds the torque of the motor the rod slips around in the drive holes clicking off of the locks. This renders the motor useless as The One and Only stated. I'm not sure but I would guess that the resistance in this project would be far greater than the torque of the battery powered motors.

[Lowney]

It would be ideal yes, although you could alter the gears to accommodate a battery motor. Perhaps a gearbox could work: http://www.instructables.com/id/Ultimate-Knex-Gear-box/

thanks

[Seleziona]

 awwww, i don't have that motor.....

[Lowney]

Shame dat

[Seleziona]

 yeah eh....

[black_hawk-69]

 can you use any moter or only that one?

[Lowney]

Only this one I'm afraid. This has more torque (needed) and has different rpm than any other.

[knexjay]

thank you Scott!

[kurtcobain132]

in my opinion this is by far the BEST knex Instructable on this site!!!!!!!!!!!!!!!!!!!!!

[The One and Only]

Could not agree more.

[976]

i think the uzi is the clock is cool though

[Lowney]

Thankyou, but it isn't my design. Check out my other instructables too

[kurtcobain132]

just finished,it looks really nice and i left of all the sides so that you can see all the cogs and what-not.

[lioneatr]

are ya a kurt fan? RIP

[kurtcobain132]

yup he rules

[lioneatr]

ruled

[Lowney]

Great! Looks good doesn't it? I took it apart since then to make way for the_burrito_master's morretti! (spelling?)

[TwistedParadox]

Just finished building it but I need to get my motor from my Dad's house now.

[Lowney]

good luck! It's pretty cool when done, what I did was make some cartoon-like cardboard hands for it

[TwistedParadox]

It may be a while because instead of going to his house this weekend I'm going Zorbing.

[Lowney]

lol that sounds like a fictional alien planet
