Shacktopus System Introduction
After two decades of building and traveling the US aboard geeked-out "technomadic systems" (Winnebiko, BEHEMOTH, Microship, & Bubba),
Steve Roberts, N4RVE, decided to build a suite of essential
communication and data collection tools into something small enough to
throw into a backpack or sea bag... the ultimate in portable gizmology,
not tied to a specific platform.
The result is Shacktopus, a fully integrated,
remote-controlled ultra-portable communication system: a self-powered and
network-enabled "Shack To Go" with HF/VHF/UHF transceiver, automatic
tuner, "sound card modes," rig control and contact logging, robot
operator, headset and retractable CW key, Packet/APRS with internal
GPS, environmental telemetry, Internet access and Wi-Fi bridging, intelligent
Li-Ion power system with solar/auto/AC charging, speech synthesis,
audio recording from any source, DTMF control from HT with voice
response, laptop & PDA front end via Bluetooth,
field-deployable free-standing antenna array from HF to 2.4 GHz, and an
on-board security system with 3-axis accelerometer and audio/video
monitoring...
...all in a sexy over-the-shoulder Tom Bihn messenger bag, with a
separate lightweight pack for the free-standing antenna array and solar
panel!
This is essentially a collection of high-performance products from a variety of vendors, all interfaced to the RigNexus control system that includes:
- Always-on ATmega128 microcontroller for resource management and control
- ARM Linux board for Wi-Fi, archiving, full rig interface, and LAN access
- Local LCD and navigation control for on-board user interface
- DTMF command decoding from embedded HT... or via cellular phone
- Bluetooth wireless link to PDA or Laptop for graphic front end
- 8-channel audio matrix mixer with on-board speaker, ambient mic, and headset
- Synthesized speech or CW responses to commands (local, via HT, or over the phone)
- Universal audio filter (high, low, band, or notch)
- 6 serial channels for GPS, HF rig control, TNC, and sensors
- SMBUS communication with power system
- Highly responsive active-object software architecture
Shacktopus blends a huge range of resources into a single
control environment that can be accessed locally, remotely via HT or
cell phone with DTMF and voice response, through a Bluetooth connection
from a PDA, or even using a browser. The system takes care of all
the dirty work... audio routing and level control, power conservation
by switching resources on only when needed, data collection, keeping
track of the battery subsystem, managing serial channels including HF
rig control and packet, and monitoring security and system
status.
This translates into ease of use, despite some surprisingly complex
behavior that results from anything being able to talk to
anything under software control. Among other things, Shacktopus lets you:
Send a command from your HT via simplex or repeater, and
receive a clear synthesized voice report of environmental, power, and
security sensors... or tell it to begin sending APRS
tracking/telemetry.
Plug in any available power source (solar, automotive, or AC), and the
95 watt-hour Lithium-Ion battery will make use of it... with the system
able to report fuel gauge and over 30 other parameters.
Log sensor variations while driving, bicycling, or kayaking... then
produce a plot that shows everything from elevation changes to the
worst moments of shock and vibration.
Quickly set up an untethered "field day" station and enjoy automated
voice or CW CQ, push-button contact logging, flexible audio filtering,
instant recording of an interesting QSO, and relaxed operation with a
graphic rig-control panel on your PDA instead of the complex
multi-level menus on most HF rigs.
Stuff it into a sealed enclosure at sea and operate remotely, log in
via Wi-Fi and peek out through a webcam or listen to live audio around
the unit, or point the 2.4 GHz yagi at a distant hot spot and surf the
web.
Run Airmail, PSK31, or other computer-supported modes without the usual clutter of a ham shack and full-size PC.
As this system flickered to life on the bench, we came to realize that there is
nothing on the market even remotely like it... there's not even a
product category for gear of this scale! The initial plan was
to strike out on another adventure with this highly mobile technomadic
pack, but then we started getting inquiries... and realized that this
needed to become a product.
Shacktopus "Product Line"
At this point, we are not shipping anything; we are still building the first
unit... the one that is going in my pack and will be shown in photos
here over the next few weeks. But we are planning to make the system
available in a variety of flavors. In general, you provide the
ham radio gear, laptop or PDA, and other "external" hardware; Shacktopus ties it all together into an intelligent system. Here's the current line-up of anticipated configurations:
Shacktopus Deluxe Suite: This stand-alone shack-management system is based on the RigNexus
board, which provides audio routing, DTMF decoder, Bluetooth, speech
synthesizer and audio recorder, local LCD, headset support, and
rig-control interface. In addition, this model includes a 200 MHz
ARM Linux board with 256 MB of Compact Flash, network-enabling the Shacktopus
without any additional computers (it even accepts a low-cost bridge if
you wish to add it to your wireless LAN). Packaged in a desktop
enclosure with a bank of screw-terminal I/O, this is designed to bring
the diverse resources of your shack into a single control and audio
environment.
Shacktopus Mobile Suite: Almost identical to the
Deluxe model above, this is designed for 12-volt operation in a
vehicle. With the range of available sensor options (including
3-axis accelerometer, temperature, humidity, and various tamper and
access switches), this can allow your system to contact you in the case
of theft, stream location-stamped telemetry via packet or wireless
Internet, give you complete remote operations from an HT, and otherwise
turn a mobile rig into a full-scale technomadic communications platform.
Shacktopus Ultralite: For maximum "grab and go"
functionality, this option provides all the resources of the other two,
but includes an embedded 95 watt-hour Li-Ion smart battery system with
full SMBUS interface. Packaging is lightweight, and is designed
to integrate into a backpack, kayak, bicycle, or other environment with
limited space and power (aggressive resource management avoids burning
milliwatts when not needed). This is the one you want
for extreme survival applications or "Field Day Anytime" - add a QRP
rig and you're ready for an expedition!
Shacktopus Casemod: If you already have a PC
dedicated to rig management and communications, you certainly don't
need to buy the extra Linux board that network-enables the three models
above. This version contains only the RigNexus board that does
all the low-level processing and resource management, and is packaged
in a standard enclosure that can slide into a standard 5.25-inch drive
bay in a tower PC case. Some internal cabling in the computer is
required, but this can result in a very clean and well-integrated
installation, with front-panel display and jog dial to allow direct
interaction without firing up application software.
Bare RigNexus Board: Why pay us to package a full
system if you have a yen for tinkering, or if you want to do
something that differs from our small collection of standard
configurations? The RigNexus board lets you manipulate 8 audio
sources and sinks, collect data from 8 analog inputs, interact with 7
external serial devices, receive commands via DTMF from a nearby HT,
issue high-quality voice responses locally or via radio, pass commands
to a connected HF rig, notify you when various events occur, pipe any
channel to an internal 15-minute audio recording buffer, and much
more. The code architecture is based on active objects and state
machines, and a "patch editor" lets you create and edit behaviors from
a PC. Signal conditioning on all I/O reduces noise problems, and
the board comes with extensive documentation... and enough hand-holding
to get you started.
Anyverter Power System: One of the primary design
issues during development of our own Shacktopus implementation involved
a high-capacity Lithium-Ion battery pack that could be charged from AC,
automotive DC, or a solar panel... and deliver well-filtered voltages
to the system. We will offer this (along with various related
components, including our new "Ideal Diode" for minimizing waste in
solar installations) for folks interested in packing maximum power into
minimum space.
Custom Systems: The first unit is but one possible implementation of our core Shacktopus
technology. From a product perspective, it makes sense for us to
focus on things that can be produced in quantity in order to keep costs
sane, and we assume that most folks will take it from there and
assemble systems with their own radios, TNCs, audio gear, interfaces,
and so on. But if you have a demanding integration problem (like
the nav station of a sailboat, the panniers of a touring bicycle, or
harsh-environment packaging for a wilderness expedition), let us quote
on a complete turnkey system. These will be built in our lab,
fully tested, then delivered or installed to fit your requirements. We
have spent over 20 years building our own successful bicycle and boat
systems... perhaps we can put that experience to work for you.
