28BYJ-48 Unipolar to Bipolar Conversion Project – Part 2

In this video we will complete the conversion of the 28BYJ-48 stepper motor from unipolar to bipolar format and drive it with an Ardunio Motor shield (Click here for shield info: http://amzn.to/1jhdlCj).  Also if your looking for the 28BYJ-48 motors, you can just click here to get a package of 5 or simply find out more these little gem of a motor.  Also for the coil pairings, in my case it was: Blue & Yellow and Orange & Pink.

Below is the sample code to run the modifed 28BYJ-48 stepper motor in bipolar mode:

28BYJ-48 Based Laser Gimbal

 

In this video you see the start of the assembly of the laser gimbal based upon the thingiverse design (www.thingiverse.com/thing:794786) with the addition of an in house designed base (on which to mount the gimbal with the stepper control boards) which can be found on TinkerCAD (www.tinkercad.com/things/kkIE3qFwVO1-28byj-48-gimbal-base).  Watch for more on this too as we move forward with the build and program with the Arduino too!

Note: We taped the bottom of the base with 0.25inch x 20TPI threads to allow the gimbal to be mounted on a standard tripod.

 

 

28BYJ-48 Based Camera Slider Part 1

 

Here is the first part of the build of the 28BYJ-48 stepper based camera slider, the base mounts came from Thnigiverse and uses two #6-32TPI rods and one #8-32TPI drive screw.  In the next video we will add the rear spacer and the slide table so stay tuned for more!

Note: The 28BYJ-48 stepper motor mount can be found on Thingiverse at www.thingiverse.com/thing:423357.  Worth mentioning is there are several mounts, so if you looking to playing around with the 28BYJ-48 stepper motors then this build would be worth bookmarking.
