Windy day.
I took advantage of the crap weather to try and get my wind meter project sorted.
For those that don't know, I've been building wind meters.
I can write up more on the history of this project some other time.
I'm currently working on version 2.
The original one met it's demise at the hands of an unknowing earth-digger-machine.
It's time was coming either way as the cell network that it uses will be turned off at the year's end anyway.
This has just increased the need to get the new one done.
So, bad weather = good excuse.
I went bashing away at it till I was ready to throw stuff. Probably four to six hours. Fortunately, Keith arrived and we sorted it out. It's so much easier when you've got someone that actually knows what the hell their doing helping you out. This project would have taken probably ten years without his help. (Thanks)
Keith got me pointed in the right direction just in time too.
He had to go, but by this point, we were in familiar territory. No worries, I was working with circuits that I'd made before instead of trying to work out how to use new ones.
Or so I thought.
After Keith leaves, I must have taken my stupid pills again, cuz I couldn't accomplish the most basic of tasks. I mean, easy stuff that I've made plenty of times before just wasn't working. ARG!!!
I checked, and rechecked and dug through my old designs. I tested different components... recently, I'd run into the problem of a bad batch of chips... how frustrating was that? I mean, out of the box... bran new shit... wasn't working??? Yeah, bad chips it turns out.
Not this time.
Everything checked out... except when I tried to use it.
Eventually, I just decide, screw it... I'm starting over!
I rebuild everything from scratch.
Then, bingo... it just works. Well, as it should.
I diagram it all. I'm not letting the working model go away. No way.
Then I take the diagram and have a look at the one I was working on earlier.
DOH!!
I'm such a moron. One simple simple mistake.
LED out connected to the positive rail instead of negative
In plain English... I had my lightbulb plugged in backwards.
I hate being so stupid.
It makes life so much harder. ;)
Well, there's my windy day ramblings for ya.
I think I'll go clean up the pile of electronics now.
