GOOGLE HPS PROGRAM
May 2019-August 2019
What is it?
Google Hardware Product Sprint (HPS) Program is a summer program where you spend 11 weeks working on the design and development of an original technical product and the last week the student will visit the Google Headquarters in Mountain View, California to assemble, test, and present your finished products in person. The product must incorporate the Google AIY Voice Kit and you had creative freedom to create anything you could imagine. During the summer, the program walked us through key activities such as Brainstorming, CAD designing, BOM, tolerance analysis, prototyping, amongst other activities in order to gain valuable insight into the product development process in consumer electronics.
My Product
The product I had originally designed is quite different from the end result, but I knew I wanted to create something that was challenging and that would help me grow in my CAD designing skills. I designed a speaker enclosure that would include a wireless charging pad and a lamp fixture that would vibe able to rotate utilizing a servo motor.

The lower component is composed of three parts, the bottom enclosure and the middle and top pieces.
​
​
​
​
The bottom enclosure includes a cable opening at the lower back part, it houses the speaker, the raspberry pi and voice bonnet and it is attached the the lower part of the lamp fixture, which by diving into two pieces, it allows more movement of the lamp. The bottom enclosure has a hexagonal design at the front, and screw holes in order to attach it to the middle piece.

The middle piece includes two set of screw holes in order to be attached to both the top and bottom pieces. It as a dent in the center, where the wireless charging pad will be resting, and an opening next to the dent where the cable of the charger will go through. Lastly it includes a button slot, where the AIY Voice Kit button will be placed. By pressing said button, the Voice bonnet is activated and you are able to speak commands unto it.

The top piece is the lid of the whole enclosure, which from the top view is simple and minimalistic, but houses more detailing at the bottom. It includes a hole for the top part of the button and a small opening from where the light of the button will shine through. The top part of the wireless charger is to fit perfectly with the lid and it has a pair of screw holes from where it will attach to the middle piece. Lastly, half of an ring is to be placed where the holes are placed in order to cover these and also give a clear visual to where the phone into be placed for maximum charging.
In Depth Explanation
The top component is composed of four parts, the connecting neck, a lamp fixture, a piece that houses ser servo and a pin which connects all three pieces together.
​
​
​
The connecting neck is the middle ground between the bottom component and the light fixture, it connects by a hinge at the bottom utilizing a normal screw and at the top it connects with a pin. It includes openings for the cables of the lamp to pass by on the top and bottom part and it includes a hole for a regular screw that connects the piece of the servo to the neck, providing support onto it and holding it in place.

The lamp fixture is the top part of the whole component. On the top it has a clean look, only showing an opening for a on/off switch for the actual lamp. On the bottom you are able to see where the switch is to be placed, having screw holes on both sides, and it also includes a snap fit for the lamp to be securely placed. The hinge is to be connected to the neck, and it has a hole for the lamp cables. On the last image you are able to observe a screw hole to which you connect the piece to the pin and a slot for an acrylic lid that is to be placed ignorer to hide the lamp and only reflect its light, creating a more simpler look.

The piece housing the servo is quite a custom unique part of the whole component. It fits the Tower Pro SG92R micro servo perfectly, also including the screw holes. The main opening on the outside is where a screw is to be inserted so it may be connected to the neck, and it also provides openings for the servo and lamp cables. Lastly, as it may observed in the last photo it is custom designed in such way that it fits perfectly with the neck, giving the appearance that is it only one piece.
The pin, a very simple design, it is the last piece yet I believe its one of the most important ones. It connects the lamp fixture, the neck and the servo piece. It has a screw hole right in the middle to which it is connected to the lamp fixture, securing it, so when the pin rotates, the lamp rotates as well. In the pin it also has an entrance for the hand of the servo, while the servo moves, the pin and lamp also revolves.
