In this post we'll talk a little about how the robot will perform a musical piece. To play every note on the keyboard using 19 solenoids (7 in 12 in the harmony and melody), they are mounted on supports that can move through the entire keyboard (as they would a pair of hands). This week two blacksmiths harvested the mineral orcs of middle earth to bring the world two sills that make the role of the media.
Cut a sheet of stainless steel in two parts of 187 mm and two 100 mm, then made small cuts to facilitate assembly. The result was as follows:
view supports the solenoids As can be seen, solenoids corresponding to the full tones dovetail assembly, such is the practical skills of blacksmiths living in Minas Morgul.
At first, due to its weight, doubted if stainless steel would be the best option to fabricate the supports, but once built, the weight proved to be acceptable, in addition, that weight can help us reduce the error of inertia that could be presented by the nature of the engines. Earrings
:
- In the following days will be made to drill the sills that hold the solenoid to enable be bolted to them. Weld
- all creation and a finished surface to remove imperfections.
- will continue the same steps for the second set of actuators which will serve as harmony, the other hand will be even lighter than the other because they use less solenoids (7 per octave instead of 12 per octave).
