The Bescor MP-101 is a motorized tripod head that in its original form is controlled by a four-button switch connected by cable. It's a popular and well-built device.
Thats a pretty nifty pan/tilt head. It can move a lot of mass if you balance the load.
Here's a link to a picture of a remote controlled camera with a huge zoom lens and infrared lights I made with one. The lights pan and tilt with the lens by the way. The pan/tilt has DC motors and gearing, thats it. No position sensing as far as i could tell. It does allow variable speed for both the pan and tilt axes. Its remote controllable through that round plug. If you wanted to use one for timelapse, I wouldn't bother taking it apart.
Just put a relay in the common wire on the remote plug. Use the relay to interrupt the movement except for a short pulse after each exposure is completed. If you have a Dynamic Perception MX-2 controller, use it to power the relay from either of the motor outputs. Any 12 volt relay should work as long as the coil draws less than an amp (pretty much any 12VDC relay). Use the MX-2 in interleaved (shoot, move, shoot) mode. The MX-2 will adjust the duration of the relay-on pulse depending on the inches per exposure you set.
Wire the pan/tilt to the relay contacts that conduct only when the MX-2 wants to move the dolly motor. You can set different speeds for the pan and tilt axes by adjusting the resistance from the common control wire to one or two of the other pins on the remote plug. This way only one motor plug on the MX-2 needs to be used to control two axes on the pan/tilt head and you can move each axis at a different speed if you want. The remote plug on the pan/tilt has five wires.

The Automatic mode worked, but the Manual mode does not, it was worn all around with grime in it. I just spoke to the company that sold it to me through amazon and they are sending me a return label, then will ship me a new one. What a pain in the butt, i really wanted to crack this thing open however they are taking care of it.
Mistakes happen. Anyway, my first impression was 'Wow, this thing is small!' It fits on my timelapse Rail Chronos 1.0 nicely. It just LOOKS like it belongs. The movement on the automatic mode is very smooth, very quiet.
The tilt was not working, if it WAS i probably would have kept it, but i did not want to find out that the tilt motor was not working. I opened the front plate, there is a control circuit in there as expected however there are a BUNCH of wires from the control circuit into the housing, i dont think they are all wires for the motors. Being a Bescor 101 i know it has a tab that hits a switch preventing a full 360 degree panning, so the extra wires are probably for that switch. Upon opening the other side (battery side) thats all it is, batteries, and a pair of wires. So all the mechanical guts fit into the central body of the unit. Ive seen pics of the body opened up exposing a couple worm gears on wevbsites that show the easy conversion from a Bescor MP101 to Mp-360. I am fully confidant ill be able to take control of this thing with a motor driver shield and arduino.
Ill be very careful to document my processess, take shots of everything. This may be about the best timelapse P&T deal on the market for the DIY'ers Another guy has created a very slick system called AUTOMATE 1.0 based off this unit, turning it into a smartphone controlled bluetooth connected timelapse?gigapan head and sells them for 400 bucks. Not a bad deal for all the development he put into it, however, if i went with the AUTOMATE i would just have to hack it to get it to work with my system anyway.

I suppose that sounds bad coming from somebody using the online name of Jack Ripper. Anyways, i digress, I ordered one of these, i got it in and last weekend my project partner and i cut it open, figured out the required voltage levels to get the motors spinning, pulled out all the automation junk, and left it bare and hollow with just the required parts. In the end, this could quite possibly be the best deal in timelapse history. Oh yeah and forget the MP-360, mine runs 360 degrees now anyway. I am chomping at the bit to get some time to do some mind control on this thing, however ive been so busy with a full time job, being a full time dad, and working on project chronos, laying the groundwork for project puppetmaster, and STILL getting headway on Project Orion that i just havent had any time to mess with it.
