NashPen: Digital Pen with TOMU: An AlexaPi project

IaC is also CaC, Circuits as Code, we introduce a uniform framework for IOT based sensor fusion and
automated persistence to AWS S3 using the per-observer design pattern defined in reactive streams. A
uniform scalable IoT architecture is in the automated code generation of Alexa Skills with both AlexaPi
and the flex echo. We introduce CaC using the TOMU board, an open source ARM v7 based architecture.
Keywords: IaC, CloudFormation, CaC, Circuits as Code, AWS, stack, SaaS, AIaaS, IoT, ARM
What:
The Amazon Echo Flex, retailing at $24.99 is presented as an attractive scalable IOT platform for use
with grid compatible IOT solutions, in conjunction with the open source Tomu and Fomu platforms for
multi sensor integrated IOT with Alexa skills and AWS Lambda cloud functions. We compare this with
the AlexPi solution, enabling IOT with inexpensive hardware like the raspberry pi zero W or orange pi, or
any scalable browser based device, as an IOT solution with Alexa. The marketing pitch for the echo flex,
remains as a power source for all the hardware supported by AlexaPi or any other computing needing a 5v
USB-A bus and thus supplements the AlexaPi.
A case study of flooding in the Lilydale Regional Park in St Paul is presented where a scalable network of
Tomu based water level indicators is hypothesized to predict flooding for closure of the park.
How:
Simple resistive water level monitoring sensors are integrated with Tomu and Echo Flex boards using the
Alexa Gadget API, USB function for an Rx formulation of Alexa IOT interactions. This allows periodic
uploading of water level information to AWS S3 for data mining and predictive analytics.
A hypothetical model to compute the operations of such a ‘N’ node grid is presented with a case study of
lilydale park and the Mississippi river.
Why:
Simplicity , robustness and cost effective solutions , lead to the evolution of the IOT or things network,
while Lora or SigFox are touted as solutions we present a simpler approach using WiFi and VUI based
echo flex units for IOT.
