How about a shot from the side ?
this is the ''BEST'' pointless ball machine ''EVER''.
it has one element, witch is the track
just made it. I love it though it is useless.
took the words strait off of my keyboard
This thing was amazing, yet so simple.
Where do you get the red gears?
My motor dose not work, it is the one like yours, but older.
were do you get motors like that!!!!!!!!!!11?!?!?
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.
LOL @ 2 things 1. your name-"alex Jolly"???? 2. that is the worlds most silly ball machine ever
What's wrong with my name?
nothing, just sounds funny. do you live in the US?
I used to.
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. _
To build this? If yes, then probably.
not that, i mean a knex gun
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?
it works though i just built it
it is not pointless its mindless lol
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.
Thanks, and I would love to see a picture.
This is it
I'll post if wanted.
post!
That will work, expect it in at least 3 days.
yay!
Yes, yay. It may be longer i don't want to mae instructions now.
well that's good; it looks pretty cool
I broke it to make ( do you know the hand held cannon? looks like a crossbow. ) a smaller version of the hand held cannon.
I remember that one
That is a Horrible horrible picture.
I may not post it i am making a sniper rifle and may need the parts.
5 stars! it's good for people who don't have enough pieces to build big ones (not me! i have enough pieces) :D
ohh... in need more rods lol
