Where do you get the red gears?
Bartboy5 years ago
My motor dose not work, it is the one like yours, but older.
Mudbud Bartboy4 years ago
were do you get motors like that!!!!!!!!!!11?!?!?
Bartboy Mudbud4 years ago
In the old sets, when they came out.
on this the speed of the motor is critical to making it work(less speed = less kick to the ball making it launch forward). try changing the batteries in it.
okay, but I did have to rewire and re solder it, as the wires broke, so ill try that

can u make this with only four big gears? i dont have 6.
You should try taking out the two outside(the ones in between the top and bottom) gears. I haven't made it myself, but it looks like it would still work. (P.S. you would also have to take out some of the chainlinks)
thanks!!!

hey, i tried to make this and it just doesn't have enough information.
you call THISpointless?!?
you have not even heard of POINTLESS until you have seen my parent's efforts to clean my room!
haha ditto :P
seriously: it makes the average landfill look clean.
well i picked mine up so i could play with knex :D
don't worry; my floor is juuusssttt clean enough to use as a workspace.

jollex (author)  DJ Radio5 years ago
What's wrong with my name?
DJ Radio jollex5 years ago
nothing, just sounds funny. do you live in the US?
jollex (author)  DJ Radio5 years ago
I used to.
DJ Radio jollex5 years ago
would this knex set have enough connectors?

http://knex.com/Thrill_Rides/motorized-madness-ball-machine.php
im not sure about connectors but it only has 4 gears. _
jollex (author)  DJ Radio5 years ago
To build this? If yes, then probably.
DJ Radio jollex5 years ago
not that, i mean a knex gun
jollex (author)  DJ Radio5 years ago
No, it has lots of blue connectors but not enough other kinds. I recommend using eBay.

I just finally finished my own "mini ball machine." (my first ball machine 2!). It is actually slightly shorter than yours. Yours is 9 to 91/2 inches tall, mine is about 8 1/2" .It's almost exactly the same length but it has a larger width. ( I did not use micro-knex). Question: I'm new to instructables and have never posted one. Do I have to actually post the instructions or can I just put up a video, like you did for Project S?
hockys15 years ago
it works though i just built it
it is not pointless its mindless lol
ajleece5 years ago
very cool!!
5 stars! BTW I modified it so it has a longer track, but still doesn't take many pieces. I can put a picture up if you want.
jollex (author)  cstrike pwner5 years ago
Thanks, and I would love to see a picture.
This is it
