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.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
Would you use your phone if it was always tied to a power cord?
Of course not!
The same goes for your Arduino compatible,
program it -> unplug it --> and Go.
As an Arduino compatible product the Mobillyo leverages the Arduino IDE and the vast code base freely available.
The processor is a powerful ATmega32U4 the same one as can be found on the LilyPad.
It runs at 8MHz and 3.3V to conserve energy.
Applications where no power is available
Application that need backup power
A great educational device enabling teaching computer classes without boxes of jumpers, resistors, LEDs and power cords students can misplace or lose.
Teach students how solar energy works including solar panel operation, battery charging and discharging, power management.
1- A 1500mAh rechargeable li-ion battery that can power the Mobillyo for days.
2- A buck-boost power converter than ensures a stable 3.3V whatever the battery voltage and converts energy at a higher efficiency than a linear regulator. Important if you are doing analog to digital conversions.
3- Worry free battery management: the circuitry protects the battery from over charging, over discharging, short circuits and over voltages.
Bluetooth low energy means mobile wireless communications.
Best in class Nordic Semiconductors nRF52 BLE to send and receive commands to your Mobillyo.
Frees up 16 precious i/o pins for other uses.
Over the Air programming of the nRF52 is possible but has not yet been tested.
The iPhone App communicates with the nRF52 using the Nordic UART characteristic implementation.
Simple ASCII based protocol.
4 LEDs with labels.
4 Push button switches with labels.
4 Slide switches with labels.
4 Sliders with labels and maximum values.
40 Character text area.
The source code will be available on GITHUB.
To simplify interaction with the phone App, we have pre-packaged a number of functions to make the communications protocol transparent:
Configure LEDs, switches, text and sliders.
Turn LEDS red, green or off
Polled or interrupt driven interface
Expandable simple ASCII based protocol
The protocol is described in detail in our protocol definition document and will be available on GITHUB.
The Mobillyo is compatible with Arduino shields operating at 3.3V. There are differences from a standard Leonardo. The 6 pin ATmega32u4 header has been moved to make room for the nRF52. The VIN pin is not connected since VIN can be form 9 to 20 volts and would trigger the battery over voltage protection. The battery voltage is available on the 5V header pin through a Schottky diode and a fuse. The SDA and SCL are duplicated on the Arduino Leonardo, we replaced these signals on pins 2 and 3 with the TX and RX of the nRF52.
All software and hardware files will be published on our GitHub page.
This will include the Xcode files for the App, the Arduino boot-loader and configuration files that can be accessed by the board manager, the nRF52 C source code (except the Soft device which is not open source) and the PCB files in KiCad format.
Personally I hate wires. With the availability of new wireless chips like the Nordic Semiconductor nRF52, there is no reason to keep them. With the proliforation of smart phones, why use LEDs and push buttons instead of a virtual interface on the phone that can be configured for each different application.
$0 We have implemented Core Data in the iPhone app so the configuration of the buttons and objects are automatically saved on the phone.
$0 We have started to develop a compatible Android App.
$0 We will develop over-the-air programming of the nrf52 BLE firmware.
$10K we will add a real time graph on the app screen.
Beyond $10K we have many ideas for improvements and new features but we rather concentrate on giving you a great backer experience for this project instead of making too many promises that may be difficult to keep.
Money-Back Guarantee: If you decide you don't like Mobillyo within the first 15 days of receiving it, you can return it for a full refund, no questions asked.
Early-Bird Discount: We have included 3 early-bird discounts for those eager to get started with the Mobillyo.
We Listen: Backer input is a valuable tool for us to improve our design.
Backers Come First: We will ship to all our backers before opening up the distribution of the Mobillyo.
We Need You: Designing and building new products is an expensive endeavour. Kickstarter gives us the funds and the volume orders we need to be succesful.
United States and Canada : $9
European Union: $12
Any country not in the EU nor the US/Canada:
Asia/Australia/NZ : $18
Risks and challenges
Having researched Kickstarter projects, I understand the frustration of backers when delivery is a string of broken promises. In order to avoid this, I chose to work ahead of time and make sure that the project was as close as possible to production before launching this Kickstarter campaign. Although a massive amount of work has been completed to ensure that production is ready, there are still a number of risks involved. Components shortages, logistics, software bugs and many other unforeseen circumstances can occur as illustrated by Murphy’s Law. The good news is we know a thing or two about manufacturing electronic boards. We have our own PCB assembly facility with 3 QUAD assemblers.
