20092017 – VK3/VC-017 & 08102017 – VK3/VC-013

Three Private Summits VK3/VC-017, VK3/VC-012 and VK3/VC-013

Not having enough time to travel across the the Alpine for a end of bonus period jaunt and keen to get out to play radio, I decided to tidy up some local summits.

These are on private land and each only activated a single time. 

20092017 – VK3/VC-017 – The Jim Jim

The Jim Jim is on private land behind Mt Macadon.

My method of finding owners for private summits is to start as close to the summit as I can and start asking. It does not take long to find who to ask. 

A review of maps show that the ‘Hanging Rock Winery’ is the closest buildings to the site. So in this case started with phone calls to the winery.

TheJImJIm

Contacted the Winery and hit pay-dirt first go. After a brief chat with the owners access was secured. Had to go into the cellar and let Andrew the manager know but no issues.

Looking for ward to testing a 20/30/40 trapped end fed halfwave that I had just made. The summit is nIce and clear and flat so setup. However, the battery was flat and the KX3 shut down. This was surprising as had charged two nights earlier and normally get a couple of activations out of the internal Eneloop batteries. I had not brought a spare up. There was spare gear in the car but decided to try with the 2M handie as it was a nice day and I had time.

Qualified on 2M, picked up a Merlot and Shiraz Mourvedre Grenache and made it back to the train station to pick up my daughter and head home.

08102017 – VK3/VC-012 Black Range.

Drove across and started the tried and proved plan of starting as close to the summits as I can. Approached a farmer at the base of the summit. He was not the owner but knew who is. The owners live in Melbourne. He would pass my details on and I will receive a phone call.  More to do here to secure access. Expect to have to chase access as not all people take the SOTA summit access quest as seriously as it should be treated. Current plan is to return in two weeks and go back to the initial contact seeking further information. May activate  Organ Pipes for KRMNPA & WWFF whilst in the area.

08102017 – VK3/VC-013 – Mt William

With access for Black Range off the cards for today proceeded to drive to Mt William. Applied the same rules and headed for the closest building according to Google maps. Drove up Staffords Lane as maps indicated it was a through road. It is but not the main access road as turned into a red steep track quickly and has gates across the top. It did look like an easement but decided not to go through the gates as it is not a good position to be negoating access from. Quite steep and great views,

MtWilliam

Obvious could not access summit without crossing private land and that this was no the road to the building I had initially targeted so returned back to the main road and drove down and turned into the first farm off Pyalong Road. There was a new house which was avoided and proceeded up to a farm house.

Bingo. Meet Noel. Hppy to chat and so it appears there are three owners of the summit. One who owns the top which holds a coms tower, another that owns the part coming from the east and Noel who has the land from the north. Noel had no issues with allowing access across his land so decided to go from his side  

Noel recommended that I avoid Staffords Rd due to it being steap (yes confirmed that!) instead to head back down Pyalong Road, into West Goldie, across Red Gat to turn into William road and eventiually Hockings Rd. Proceeded as instructed and parked the car at the other end of the easement as saw no reason to push through the gates. Walked across then up towards the summit staying on Noels side. Setup in once in the zone but off the top. Nice clear spot but compromise so not expecting brilliant results. 

Setup the EFHW 20/30/40 .  Quite activation and had to go to 80m to secure local contacts. The internal tuner in the KX3 tuned the end fed to secure 80m contacts. The intent of the antenna is for use with MTR where weight is going to be an issue. Picked up a a S2S with VK3CAT Tony on VK3/VC-002 Mt Donna Buang again on 80m. Spent an hour calling on each band and packed up and back at car well before the rain came down.

Have not heard back from the owners of VK3/VC-012 Black Range so will plan a trip to activate WWFF Organ Pipes National Park (VKFF-0627) and VK3/VC-007 Mt Macedon and go back to request additional contact information.

IoT

Internet of things
noun
 
  1. the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data.

Intend to build a home sensor network based on Arduino and Raspberry devices hosting environmental sensors and home voice activated automation system. Guess this is the Intranet of Things – IoT

Late to the story but can see where this is going. Can remember early days where we were being trained in digital electronics and the wait to access microcontrollers. You can now purchase for next to nothing multi core devices and the tools to develop and interface are amazing. 

Picked up a couple of Arduino’s and a Raspberry PI to play with. A kit of sensors off eBay was sourced so as to get a spread of what we can monitor. Its just a case of integrating the pieces.

AllNet OverviewCurrent overview as at 102017.

Like all IT deployment security and scaleability have to be the predominate design factors;

“if one thing can prevent the Internet of things from transforming the way we live and work, it will be a breakdown in security”

Current design is simple and will not be connected to the Internet. Voice control will be will Jasper on Raspberry Pi. Pocketsphinx as the STT (Speech To Text) engine so recognition will be performed offline. Not just to keep my data off the Internet but to conserve the rural connection. 

Features;

  • Multiple Andriod based sensors
  • RF based sensor network
  • Raspberry Pi hosting Jasper automation
  • Linux based presentation layer
  • Remote control of external (chicken door) instances
  • …..

The “user manual” that comes in the case is a picture in the lid for a 37 in one kit so will work through each one at a time.

Manual from Jaycar for some of the sensors 

Libraries:

Notes:

  • The digital pins 0 and 1 are used for serial communication. As long as you aren’t doing serial communication (including uploading sketches), you can use them for other purposes but you loose the ability to communicate and up load sketches.
  • The analogue pins are for analogue input only not analogue output. You can use them like any other pin by referring to them as pins 14 to 18. They can be a digital input or a digital output.
  • Arduino works with 5 V and Rasp Pi with 3.3 V. Add a resistor divider to lower the voltage to something between 2.2 and 3.4 Volt. At divider with a (bottom) 3K3 and a (top) 2K2 resistor will divide the 5V to 5x(2.2+3.3)/3.3= 3V, so yes its possible to use many of the modules, but they are probably designed for 5V devices.

4. Temperature and humidity sensor module

LM315 Temperature and Humidity Module

  • Humidity Range: 20-90% RH 
  • Humidity Accuracy: ±5% RH 
  • Temperature Range: 0-50 °C 
  • Temperature Accuracy: ±2% °C 
  • Operating Voltage: 3V to 5.5V

The DHT11 humidity and temperature sensor appears to be an easy to add humidity and temperature data. Such a device will fit into the current ideas of a ‘sensor net’ which include home environmental monitoring (internal and external) as well as a garden monitoring systems. Given the dual information in a single chip and use of a single data line then is may included on the base board for all sensors.Will need to look into sourcing the chip seperatly

Arduino Bluetooth HC-06

Arduino Bluetooth HC-06

Bluetooth HC 06

HC-06 Wireless Serial 4 Pin Bluetooth RF Transceiver

Description:

  • Bluetooth module for use with any microcontroller.
  • Uses the UART protocol to make it easy to send and receive data wirelessly.
  • A breakout board for easier connectivity
  • Designed for 3.3v level ttl but will accept 5v level as well
  • Built in antenna with a range of up to 30 feet (range is dependent on a lot of things such as any obstacles or walls in the way so it may vary)
  • Supports baud rates from 1200 to 1382400 bps (default is 9600 bps)
  • VCC input voltage 3.3v to 6v
  • Bluetooth Specification v2.0+EDR
  • The HC-06 module is a slave only device. This means that it can connect to most phones and computers with bluetooth but it cannot connect to other slave only devices such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave.

Connections;

  • Connect the HC-06 Ground (GND) pin to ground (duh!).
  • Connect the HC-06 VCC pin to 5v.
  • Connect the HC-06 TX/TXD pin to Arduino digital pin 4.
  • Connect the HC-06 RX/RXD pin to Arduino digital pin 2.

The Software Serial library comes pre-installed with the latest version of the Arduino IDE. It has been developed to allow setting up serial communication on (almost any) digital pin of the Arduino, using software to replicate Arduino’s native serial support. See the SoftwareSerial library page for more details on its features and limitations.

Conclusion:

Unfortunately this device does not work with iOS based devices.There is no workaround. HC-05 simply doesn’t work with iOS, because iOS only supports a few Bluetooth profiles. This is because Apple uses MFi Licensing Program. What does work is BLE. It’s not part of MFi.

HM-10 and HM-11 are the BLE brothers of HC-05/06, and rumor has it that they work fine with iOs and Android

18102017 – Ordered an HM-10. Wil not bre requiring every device to have BlurTooth capabilities but do want a iOS interface so will have on the internal master.
