31  Using Arduino / General Electronics / Re: Rabbit killer on: December 31, 2013, 07:33:08 am
I think I'll use an electric fence about 6 inches above the ground in the area the rabbits frequent and see how that goes.
Good idea, we've used a few high powered ones that will knock a bull back, sure it would send a rabbit scurrying.
Also if the ground around the fence is wet a much more powerful zap is received.
I'd string the fence at 4" , 7" and 10" as rabbits are contortion artists and great jumpers , small ones learn to squeeze below the 6" line. Or maybe use some 1" holed stainless steel chicken wire as the electric fence in the area needed.

Oscilloscope handy to test output?
I also built this awesome project (pic attached) and after button/sound issues figured out that I needed to use the ATmegaBOOT_1284P_16MHz.hex bootloader file, after that it works great.
I used these for piano keys.

I've ordered 20+ Pro Mini clones from here.
Just ordered 3 more today for a project, under $3 can't complain. And these have proper upload.
Have tried other Pro Mini clones that need the reset button manually pressed for proper upload.

What are you planning on using it for? All are not created equal, maybe read a few datasheets before purchasing.
"least expensive" might not offer what you need.
35  Using Arduino / Sensors / Re: Piezo sensor sensitivity. on: December 29, 2013, 09:35:39 am
Yup, also check out that product line before you buy, as there is a larger one.
36  Using Arduino / Sensors / Re: Piezo sensor sensitivity. on: December 29, 2013, 07:51:48 am
Maybe this Piezo Vibration Sensor has the sensitivity your looking for.

Linear and ratiometric are the same thing, output is proportional to applied magnetic field.
Digital output hall sensors are, latching, unipolar, omnipolar and bipolar.

Ok, got it now. Had to follow this advise, install it over itself, now it works.  smiley-wink
Thanks

Using Win7, can't get Tortoise SVN to work. Any other way to grab this library?

Have a multimeter handy? Test your connections to and on the module.
41  Using Arduino / Sensors / Re: Problem with DHT11 on UNO on: December 26, 2013, 03:20:47 pm
You need a 10k ohm resistor connecting the +5v line to the output pin on the DHT11.
Like in this tutorial.

Sounds good even with the high compression.
Can't download from your wiki, have a different link?
43  Using Arduino / Project Guidance / Re: Talkie library + a little GLCD help on: December 25, 2013, 01:33:18 pm
You don't "control" the hexadecimals. For your own words you need to record them on your PC, then use the encoder included with the talkie library, then manually convert to hexadecimals and use that.
It is NOT an easy process.
The better way of using your own words is to get a dedicated speech module like these: Ginsing , Speakjet voice sheild or an eMic2.
44  Using Arduino / Project Guidance / Re: Talkie library + a little GLCD help on: December 24, 2013, 02:16:15 pm
I have made a talking clock/thermometer with the Talkie library, it works well.
I went off of this code .
The library is quite simple, I suggest working off of the Vocab_US_Clock example, it's pretty straight forward.
Include the words you want to use, and call them in your sketch using:
Code:
voice.say(the word you want here);
As for the 0x values.
The words are stored in hexadecimal format, nothing for you to play around with or the words won't work.
45  Using Arduino / Audio / Re: Arduino uno audio delay project on: December 23, 2013, 06:48:24 am
Ever think of using a dedicated delay chip with an UNO?
Such as one of these: V3207, V3208D or V3205SD
Or the more expensive Panasonic MN3200 series like the MN3205
