So i got excited today and tossed the BITx 40 and a 7ah sla onto the back seat of the ute and headed off to play a little radio. To be honest its been a really long time since i have gotten out and about in vk and did some park activation. The BITx is a bunch of fun to operate with its huge 7w and a lack of all creature comforts, but it does the job even if you have to ride the volume knob for when someone big gives you a real signal.
So I spent about an hour in the park and made 21 contacts. Not to shabby all things considered as its a work day and the band conditions were poor. The only non vk2 and 4 contact made was with Paul vk5pas and thats because he lives on top of a mountain and has pretty good antenna, but even with his superior location the best he could give me was 33 to his 56.
Anyway, i had fun and look forward to getting out and doing some more parks soon, it has really been a long time since i have done any, other than an an activation in the teams even with 4aac i have not really done a park since Easter. Bring on more wwff and more activations.
Oh and its time i fixed the displayed frequency, im actually on 7.149 irrespective of what display says HAHA.
Its been a while since i have posted anything to do with electronicals and as i have been tinkering with the its been taking forever weather station i thought i would post an update.
The major change has been to the power system. I found these rather cool Wemos 18650 boards that take care of charge, voltage boost etc etc for a couple of bucks. The specs are perfect for all sorts of projects and will match up perfectly with the 6V solar panel i have to go with this and will charge at a max of 0.5amps. The cheep lipos have a combine capacity of 3.5amp hours, and the project atm draws about 0.1 amp hours, so good for say 30 hours without sun, which in Brisbane should be more than enough, if not I will buy some real lipos and use them instead, but, once i start dropping the micro into standby, that current draw will drop dramatically.
I have the code all working for the modules installed, humidity, temp, pressure, rain, I still have Lux and UV sensors to install. The code will poll the sensors every 15mins, save the data to SD card and push a copy of the data to my home server where I am still working on a web interface and graphing to display the data. High and Low data for the day is saved at midnight and pushed to the home server also.
And not to be outdone, I have even done some woodwork and 1/2 built a house for this which will then get installed in the garden. Also I have coming from china a rain gauge and depth module for measuring how much rainfall there has been, the rain sensor i have in the above image just detects rain, not how much or how intense it is.
