Just a stir

Not denigrating the enthusiasm and dedication of home brewers of the complex technical geek persuasion - it stops them hanging around street corners in Kings Cross ... but I still can't understand a word of this post on another forum :cool: - it's somehow related to making beer.

Aren't we lucky that here on this forum we just make beer???? :thumbs:

Steve,
Looking at your schematic, I see you have pull up resistors on the buttons. Is there any reason why you did this instead of using the internal pull up resistors on the arduino/atmel? Also, I am guessing that you used transistors for the heater and buzzer to be more compatible? I suppose that is a good idea even though some options would be able to use these low output voltage and currents with no transistors.
Very good work smile.gif


Edak,

just a left over from my PIC days, I have always put pull-ups on my push buttons. I know that I could have driven the SSR directly from an output pin but I wanted a LED driven off the same pin, then you know on light no output, with a 1.2v drop across the LED I was getting very close to the 3v operating limit of a SSR so I decided to go with the transistor. With the buzzer have you ever heard a piezo at 5v its not very loud so again I went with the drive transistor. Its good that I posted the schematic because looking at it I have noticed some errors like the +5v supply on the relay and the use of BC 547 instead of 2N2222a which is what I'm going with.

cheers steve

Good Day BB,
You must been watching the American (Sepponian) forums, where how to make equipment to brew IS more Important than what you BREW!

Beachbum,

Whats wrong with Kings Cross? I spent a week there back in 1966! I had a ball! At least what I remember of it!

I think BeachBum was working there back then? I hope no money was exchanged between you two :lol: :lol: :lol:.

I could translate if necessary, I'm an electric brewer.

Bob, you've solved a mystery. I was there in February and was walking up a narrow street of terrace houses. There was a Woman and her young daughter talking - I paused for a moment to listen to their charming conversation "Mummy, Mummy I can never remember what day my Birthday is". "That's easy darling, - it's actually the same day as the anniversary of Bob's Streak" - "oh that's right Mummy, how could we ever forget that".

:whistle:

You guys are too much! I had a lovely time in the kings cross area (visiting churches) and admiring the architecture. You presume that as a Vietnam solider on leave I was up to no good? ....Oh?, Yeah, now I remember? I guess your right? I was up to no good! "narrow street of terrace houses" I do remember something like that? Funny that I actually remember more about spending a week (Down-Under) than a year in the jungle? I must be selective or why I drink?
