Essentially, I want anyone who has an interest in time-lapse photography to be able to produce a programmable camera dolly at low cost and add a new dimension to their work. I want to polish the code further, make a Solidworks parts list and a laser cutting AI file, and include full directions for creating such a dolly. Finally, I would like to release a final design. In this case, the same process worked equally effectively using a lighter near each plastic placing hole. In most applications, the holes for which bearings are meant are heated (so as to expand the fitting space) and usually the placing material is metal. Secondly, I just want to mention that the process for fixing the bearings was pretty cool. Firstly, 400 step steppers was definitely overkill – 200 steps would have sufficed. This next video shows the machining of the contact plate on a Haas Mini Mill.Ī pictorial documentation of the manufacturing process can be found > here <<<. The following test was filmed on my roof. In this case I overlooked a very simple and avoidable mistake. Finally, a digital servo should have been used instead of an analogue servo. Instead, the laser-cut acrylic should have been reserved for completely 2D components. Time should not have been spent making 3D assemblies by gluing the edges of flat acrylic. Secondly, a number of parts should have been 3D printed instead of laser-cut from acrylic. Essentially, without needing a CNC mill, the manufacturing process becomes cheaper and faster. Instead of milling such a contact plate, perhaps conductive washers fitted around the vertical axle could have been used instead. Without going into to much detail, this iteration used a copper contact plate that required CNC milling. For one, getting current to the servo that panned the camera up and down should have been approached differently. With respect to design and manufacturing, there were a number of simplifications that could have been made. I'm not sure if this is due to the limitations of the Arduino or simply a lack of an extensive understanding of it's memory usage. Rotating the camera horizontally on top of the slider creating a panning movement Rotating the camera vertically on top of the slider creating a tilting movement Another complication is that the camera slider needs to be programmable by the user so that they can change the movement, timing etc. Join over 36,000+ makers on Adafruit’s Discord channels and be part of the community!
