1. This is my version of a diy pocket dolly, driven by an adjustable 12V gear motor. The power comes from 8 AA rechargeable batteries, which are integrated into the controller. The dolly is pretty light and compact so that it fits in a backpack and I can take it with me on walks and on holiday trips.

    UPDATE 2011/06/19
    Have replaced the hose clamp for a fixed metal ring that slides in over the lens when zoomed in, then matches focus ring perfectly when pushed toward it. A big time saver! Check it out on my website!

  3. I recently finished this self made camera crane which
    has a 3m50 span and a max height of 4m50.
    It took me a few weekends to build it, as every minute in the workshop took like 10 minutes of thinking before. And there is still room for improvement, but so far, I'm quite happy with the result.

  4. This is just a video showing the Motorized system I build for my Igus Slider.

    I saw a few different ideas that I liked but I just wanted a super simple version. So I used a string.... Can't get much simpler that that. The continues rotation servo has a spool on it and it simply winds up the string. Not quite as convenient as a belt driven design because it cant really go in reverse but hey I'm not complaining. If anything I can reset the carriage faster by hand then a belt can... Anyone can build this too. The belt drive design takes a little more work to get running but it is a little nicer.

    I think eventually I just end up getting one of the really nice ones once I save up some money but first I just wanted to see if Id really use something like this and if its worth all that money.

    Oh yeah And I did this with Zero modification to the slider itself. I mounted the servo to a aluminum plate then mounted the plate to the slider using the hole that was already drilled.

    The consensus?.... Im going to need some money :D

    [UPDATE]

    Since a few people have been asking how I did this I decided to do a parts list.

    Ok for the servo there are a few different places you can order from.

    I got mine from here.
    servocity.com/html/hsr-1425cr__continuous_rotatio.html

    You could try here:
    robotshop.com/parallax-futaba-continuous-rotation-servo.html

    or here
    hobbypartz.com/12exiseb1.html

    But, someone said this one will only do 3 revolutions even thought it says "Continuous revolution". You could always send it back.

    I got this riser to get the spool to the right hight.
    servocity.com/html/servo_shaft_attachment___375__.html

    And Here is the spool I got:
    servocity.com/html/pulley_wheel__futm2045_.html

    For the Servo Controller there are also a few places you can get them.

    I got mine from Here:
    .towerhobbies.com/cgi-bin/wti0001p?&I=LXWGJ7&P=7

    But theres also Here:
    servocity.com/html/dual_servo_driver.html

    and Here:
    hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=6554

    I know for a fact that mine is reversible. Im not sure about the other two.

    And to power it I got this.

    pololu.com/catalog/product/1159

    its very inexpensive, it uses AA's so its cheap, quick, and easy to replace the batteries. It also has a switch built in so thats your on and off.

    You need the 4 cell version because the servos run of 6 volts.

    4 cells X 1.5 volts (per AA battery) = 6 volts.

    I think you might be able to get away with 7.2 volts but rather then risking burning out the servo I just stuck with 6v for reliability.

    You also can get rechargeable battery packs from Here:
    .towerhobbies.com/cgi-bin/wti0093p?&C=MFB
    But you also would need a changer.

    To wire it all up I got a few of the futuba versions of these:
    servocity.com/html/female_servo_leads.html

    and these:
    servocity.com/html/male_servo_leads.html

    and for the cable running from the controller to the servo I got one of these:
    servocity.com/html/48__servo_extensions.html
    I got the super duty version because I thought this would take the most abuse.

    Any questions please ask!
