About

My name is Tom Murray. I am an Industrial Designer who successfully funded the SmartiPi Raspberry Pi B+/2 case here on Kickstarter last year. I had a blast on that campaign and learned quite a bit. 

Since that campaign, the Raspberry Pi A+ and Raspberry Pi HATs have been introduced to the public. We listened to the needs of SmartiPI users and have combined them into a new product called the SmartiHat. The SmartiHat is a simple device that enables you to mount any Raspberry Pi A+ or Raspberry Pi HAT. The only constraint is the clearance underneath (5mm), which should not be a problem for most HATs. 

The images below are 3D printed prototypes. I have created numerous iterations of the design and 3D printed them to refine the design. Once the project is successfully funded, we can pay for injection molds to build the plastic parts.

How to use the SmartiHat

Snap and screw you Hat or A+ to the SmartiHat.

Snap and screw your HAT or A+ to the SmartiHat. Once it is secure, connect the included rainbow ribbon cable. The HAT is now secure and can be mounted or positioned with the screw holes or LEGO compatible bottom.

The ribbon cable connector connects onto the HAT header between the snap features that hold the edges of the HAT. You can also buy longer ribbon cable to use with the connectors I will supply. The connectors and the cable will come unassembled to allow you to customize your ribbon cable length.

You now have the ability to mount and position your HAT in all sorts of ways.  The ribbon cable can also be routed under he SmartiHat as shown below. You will have to raise the SmartiHat with a few LEGO pieces. Connecting two SmartiHats together enables you to connect your A+ to a HAT. Then, build a great LEGO A+ enclosure around them.

Rewards

There are a few reward levels. We are also including the Pimoroni Unicorn HAT in some of the reward levels. The Unicorn HAT is one of the best HATs available. 

 If you would like to create your own custom reward that is not shown, please contact me and I will tell you how much to pledge.

Building an A+ LEGO case

You can use the LEGO compatible bottom of the SmartiHat to build a custom and secure A+ LEGO case or enclosure. 

The design below is just one example of a LEGO enclosure. Let your creative beast free.  

  • The USB port aligns with a two stud opening on the side. Some connectors might not fit through the two stud opening.
  • The micro USB, HDMI and audio openings are accessible on the side. 
  • The ribbon cable exits out the back. 
  •  The micro SD card is set back from the edge of the LEGO enclosure, but is still reachable with a little bit of effort.

Because of the thickness of the LEGO bricks, the connectors are set back from the edge. You will have to leave openings for your size connectors, or you can partially cover up the ones you don't need. The micro USB, HDMI, and audio connectors on the side overhang the LEGO studs as shown in the picture below.

I have optimized the design to fit the cables at my disposal. I cannot guarantee all cables will fit in the enclosure that I show above. But because it is LEGO you can probably build something that will work with your setup.

Where will the money go?

The money raised will pay for the injection molds. It will also be used to pay to manufacture the parts molded from the injection molds. Finally, it will pay for the shipping. International shipping is very expensive and I have worked very hard to lower this cost as much as I can for the project. 

Shipping

The rewards will ship via United States Postal Service First Class Mail. US backers should receive their reward in 3-5 days after shipmentTo addresses outside of the U.S, it will take 10 -14 days after shipment. 

Most rewards will have a tracking number. The exception will be International backers receiving Reward #1 or #2.

International tracking will work in most countries. For a full list click here.

Project timeline

If the project is successful, we will immediately start building the injection molds with our Chinese vendor. This process is estimated to take 7 weeks. After that, the parts will be produced and shipped to me. Upon receipt of the product, I will package and prepare the shipments. I estimate delivery of rewards to be mid-September 2015.

Risks and challenges

After the project is successful, we will build the injection molds. It is a rather simple design. Because of this, I do not suspect there too many issues arising. I encountered a few delays in my last Kickstarter campaign, from which I have learned. I eliminated those risks in this project.
