Bescor Mp 101 Manual
Apr 18, 2012 - The Bescor MP-101 pan and tilt is a great cost effective solution for video and photo setups, but it has several limitations. Starsat 9000 hd wifi mise a jour google earth. When I bought a Bescor MP-101, the original remote only allowed movement on one axis at a time.
Update: Thanks to, there is a better way to connect the Bescor to the Arduino instead of using the Motor Shield. I’ll try to get a working prototype up this week.
Here’s the [av_video src=’format=’16-9′ width=’16’ height=’9′] The Bescor MP-101 pan and tilt is a great cost effective solution for video and photo setups, but it has several limitations. First off, the only allows movement on one axis at a time. Also, the speed slider is difficult to use while panning. I searched for a better remote, but couldn’t find one at a reasonable price, so after trying a few experiments, I found using the Nunchuck, the, and the together, I could make a great controller. Step 1: Strip the MIDI Wires I’ll be using a five pin MIDI cable like. It’s also possible to use the original cable.
(Note: The wire colors from other cables might be different from the original cable.) Step 2: Strip the Nunchuck Extension Wires To connect the Wii Nunchuck controller, I used extension. Yellow – Ground Black – Clock Red – Data Brown – Power These wires will connect to the Arduino pins and later I’ll show in the code the pin assignments. If you use a different extension, the wire colors might be in a different order. Is the Nunchuck pinout.
Step 3: Connect the Nunchuck Wires to the Arduino Motor Shield The wires are connected as followed on the motor shield: Yellow – GND Black – A5 Red – A4 Brown – 3.3v Step 4: Connect the MIDI Wires to the Arduino Motor Shield The wires are connected as followed: Yellow– (-B) Blue – (+B) Purple – (-A) Red – (+A) Yellow/ Blue – Tilt, Purple/ Red – Pan Step 5: Program the Arduino In this step, the and drivers need to be installed on the computer. If anyone’s interested in a in depth tutorial about using the Arduino software, please leave a comment. (Update: Here’s a to installing the Arduino Software.) Here’s a to the library we’ll be using to get the Nunchuck working. Each line of code below will be labeled and hopefully help you understand the process. If you have any questions, please or leave a comment. Matt, Someone pointed me to your site wondering why you used a motor shield, and I’m a bit unsure why you chose to as well. Download windows 7. Here are my observations: It seems the original controller simply tied each direction button to GND (through a resistor).
To mimic that, directly attaching each direction wire to an IO pin is suitable. A motor shield is a H-bridge driver; meaning it expects to be directly connected to motor coils. To move one direction, it attaches one wire of the coil to positive (+) and the other to negative (-).
To move the other direction it reverses which wire gets + and which gets. I think it happens to work as it is because one wires ends up getting pulled to negative (-) like the original controller use to do. However this must mean there is a common negative connection between the Arduino and the camera mount. He used a MIDI cable that does not bring out the negative pin on the controller connector, so I don’t see how that common connection is made. It may be that the H-bridge tying the other direction pin to positive (+) is actually creating a common positive (+) connection between the controller and the mount, and the forced voltage differential created by the H-bridge brings the other controller pin close enough to it’s own negative (-) connection that the mount moves. So this is working, but it’s a very convoluted way to go about it. Am I missing something to why you are running these low power control wires through a large motor shield?
You might also be interested in this product that uses the Bescor. It is different in that you use a phone app to define the task (pano, timelapse, HDR, etc) and identify the characteristics of your camera and lens (focal length, aspect ratio, crop factor) and various timing information, Once you make those settings, you save them in a file on your phone that you can reload at any time. The phone app then generates a program that it transmits to the head via Bluetooth, and the embedded microprocessor interprets the program to operate the motors and fire the shutter.
