1216  Using Arduino / Project Guidance / Re: Several Things about an High Altitude Balloon on: November 14, 2011, 01:56:45 pm
I've been sending up low altitude balloons with various sensors.  Last week one flew 10 miles then came back to me!  Only 10 yards away.  Crazy...

2) Openlog - I've got some experience with it.  Very easy to use.  Hook up +5v, Gnd, data to pin 1 only 3 wires.  Set baud rate.  Start sending data using print.  This all works fine if you send it slow enough.

You've got me beat!  I think it was 48k with a Timex Sinclair or maybe Atari?  If I recall much of the work was done with hardware?

True.  But it can do PTP or Picture Transfer Protocol with many camera models.

I'm using this one.  It's 640x480.  The best thing about it compared to Sparkfun is that it works!
1221  Using Arduino / Project Guidance / Re: AT Commands question on: November 12, 2011, 10:51:48 am
I am using different hardware, a Motorola RAZR.  I have been unable to put it to sleep using AT commands, it appears they are not supported.  Instead I turn off 5V to the USB port.  Since it's a mobile phone it goes to sleep on it's own.  The only thing we have in common is AT commands.  I'm interested to know which one you decide to use, and if it works.
1222  Using Arduino / Project Guidance / Re: Mega battery question on: November 12, 2011, 10:32:44 am
I am making something similar.  What functions of the camera does it control?
I am moving the camera with motors.
1223  Using Arduino / Networking, Protocols, and Devices / Re: Recive phone call on: November 12, 2011, 10:24:44 am
I have been using AT commands to send and receive SMS, make phone calls to alert me, answer incoming calls.  I'm using a Motorola RAZR with USB host shield, so there will be some minor differences between my code and yours.  But the basics are the same.

I did something similar in 1980 using a 1Mhz CPU, with far more than 2 words.
So it is possible!  Yes, the vowels are the key.

Is this sensor capable or recording audio too?
Or does it only measure energy levels?

I appreciate your answer. I guess nobody else knew it, or they were challenging or quizzing us by bringing up the topic, then ignoring the questions about it?
1227  Using Arduino / Audio / Re: [noob] Music responsive visuals on: November 03, 2011, 08:16:51 pm
Just make sure the voltage is between 0-5v to go into A/D.  You need to choose a time interval to measure the sound level.  During that time look for the maximum and minimum sample value.  Subtract.  Scale to a range you want.  I can write you some pseudocode if you like.  You can fill in the details.

You're right, if you're going to use a PC anyway, there's no need for Arduino.  How many inputs does a sound card have?  If there's only 2 I can see an advantage to his method.
1229  Community / Bar Sport / Re: Your latest purchase on: November 03, 2011, 02:36:18 pm
Instead of Ruggeduino, a few extra 328 chips.  I bought german dark aluminum powder.  Better than Gold for some things...

How many tracks?  That's easy.  Sample them all at once.  Either a simple envelope follower circuit for each track or do it in software.  Don't let anyone tell you the Uno doesn't have enough processing power.  Your project sounds simple compared to FFT.  First some simple calculations.  Let's say N tracks.  60khz/N = how often you can sample each track.  If N=60 then only 1khz, which will miss the high end, but over time it doesn't matter.  How often do you want to calculate a sound level?
