Unfortunately it's not that simple since PH-scale isn't linear but logarithmic with base 10.
If dropping the PH value of 1 litre from 7 to 6 requires 1 ml acid, dropping it 1 point further requires another 10 ml.
You would need to know the acidity of the water you're using and the acidity of the...
Yep and it may even be simpler as I initially thought, although I also... have little experience with the method below.
Using the remote desktop function, you could compile and upload arduino sketches as if you're in the growing room.
You wouldn't need a special link (processing/Gobetwino) to...
I was thinking KJ, you could buy a webcam, wifi-stick and 2nd hand thin-client computer, that way you could use your phone to see what's happening without wasting too much power or money.
By just plugging in the arduino to an USB-port that would also make it possible to control the arduino by...
@KJ
Webcam will probably be difficult.
You can do _a lot_ with an 8-bit Atmel micro controller-chip, but if you should compare it to a pc, think of an 25 year old one with close to no memory :-)
Most 8-bit micro controllers nowadays end up in washing-machines, microwave ovens, thermostats...
I'm not using win7, but guess it shouldn't be different.
I don't know where you placed the Arduino-IDE, you can place it anywhere, in my case it's on D:\Arduino.
D:\Arduino\libraries would be the map to add new libraries.
Each new library needs it's own map, in the map...
It may be difficult, but I would try to talk to those "damned doctors". (have been there as well)
One thing I've learned is to find the right doctor, should a doctor not be open to listen what you have to say, simply go for a second, third or fourth opinion and don't (!) wait too long if you're...
On April 20st 2012 many people with an affection for cannabis from all over the Netherlands and from many international countries are coming to Amsterdam.
They are coming to show that they will not let themselves be discriminated against by the Dutch government.
The new Dutch ‘Weed...
I'm not exactly sure what is possible with HHS, hadn't heard of it and just had my first look. Apparently it has quite some potential. It's a system, controlled by PC, using Phidgets or... all kinds of specialized USB-slaves/ building blocks.
By looking at the arduino code The arduino is used...
I guess Angeline has a serious point here, I don't have MS, but can imagine driving without THC and having MS may be more dangerous.
For me driving safe depends on how long I've been using. Driving stoned after being sober for a month will be a lot more like flying and isn't a good idea. A...
Hope I haven't posted my other message wrong in the other scientific data section, here's what I've written...
I do have E., but don't notice much difference in the number of seizures using cannabis.
My story...
Strange thing is that I probably had E. all my life, but never knew that...
Great thread,
Just subscribed 420 today and this is the kind of info I'm interested in :thumb:
I've been busy for a while as well and besides Arduino I also use Bascom to program Atmels Atmega& Attinychips. Quite similar to Quick-basic and often compiling to smaller programs.
So far I've been...
Hi,
A lot of messages on this subforum, but apparently no... responses.
Anyone here who also has E. and care tot tell how Cannabis effects their epilepsy ?
Personally I do have E., but don't notice much difference in the number of seizures using cannabis.
My story...
Strange thing is that...
I'm new to this forum, but not new to :yummy:
I've been growing for a while now, both in- as out- doors. My fingers aren't as green as I wanted, but I can handle a solder-iron quite well.
I love designing building and programming electronics and although my own shadow still will be the best...
