What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Virtually unlimited possibilities coming together with a very attractive price. Let us start here with a new generation of smart power supplies.

Technical aspects

  • Onboard webserver using RNDIS protocol.
  • No driver installation for Windows, Linux, Raspberry PI.
  • macOS also supported after installing HoRNDIS driver.
  • DC/DC converter based on high efficient gap-less Zeta technology:

  • Super high total efficiency factor allows using large band of USB 2.0 specified 2.5W area:
Current output limitation at 2.5W
Current output limitation at 2.5W

Steps to do

  • (January) Ordering all electronic components, cables, clamps
  • (January) Place order for case production to my injection molding partner
  • (January to March) Doing final development on firmware and website GUI, intensive testing on all supported OS
  • (April) In-house production: Adding components to final siru.box® product
  • (May) Shipping

Future

For me, this is just the beginning of a series of new smart power supplies. I need your help now to follow my ideas. If this Kickstarter project is successful, I'll be able to continue developing the next generation 15W USB Type C version.

Risks and challenges

All technical aspects in circuit design are well tested and confirmed. Potential risks may be problems with delivery times of electrical components.
