1216  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?

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.
1222  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?

How could we do this today?  I have a need for it.  100 channels.

Portable data logger

A line of full featured, rugged data gathering products that tie directly to thermocouples or voltage output devices has been introduced by MetraByte.  The DDL-400 data logger allows the user to configure systems to meet specific application requirements in the lab, factory, or field.  The IBM compatible programmable, menu driven data logger offers 16 analog input channels, 4 digital inputs, and 16 alarm outputs.  A sealed membrane keyboard controls functions such as interval, Hi/Lo alarm limits, channel select, and time settings.  The LCD readout shows channel data, limits, and status.  Each data logger requires an I/O panel, a slide in module that has 16 single ended inputs for a thermocouple voltage signal, as well as 16 TTL logic level outputs and 4 input channels.  Each channel is configured by a 10 position range switch.  Every alarm is independantly checked at full speed at least every 4 seconds.  Limit values are stored in non-volatile memory.

Expansion from standalone to complete system is simple and easy.  As many as 5 data loggers (for a total of 80 channels) can be networked together using the RS422 ports on the unit and wiring to the PC. 

No programming experience is required for set up.  Once data is taken it can be sent to a printer, or sent to one of the DB-2000 data buffers.  Suggested applications are temperature monitoring, field environment experiments, benchtop data gathering, industrial equipment monitoring, and remote data gathering.

Prices for the expansion data logger range from $995 to $1295.  The DDL-SW application software costs $995.  The TCV-16 I/O module is $345.  A complete line of accessories, including cables, adapters, memory buffer, battery backup, rack mounting kits, driver, and relays is also available.  The total to get started is $2,335.

My point is that you can sample 5x in 100us.  Not simultaneously.

What should we do when switching the ADC mux rapidly?
I guess I'm already doing it, because the data is good?
1226  Using Arduino / Project Guidance / Re: Can arduino Uno read multiple sensor inputs simultaneously? on: November 03, 2011, 11:06:10 am
Yet we can sample at 60Khz plus.  Google FastADC.
1/60Khz = 16us
Please feel free to correct my math.

Thank you for asking!  That's very polite.  If you'd like.  I wanted everyone's opinion on the question I asked above.  Curious if the popular perception matches the reality before I get started on the project.  Hence Project Guidance.  We have already seen that most people believe the Arduino cannot process or sample audio at a decent rate.  Wouldn't it be funny if it could be done 25 years ago???

If my goal is impossible, someone please tell me before I start coding.

I have Beat detection working, and FFT in software.
Never say never!

@Crossroads - It'll work with my new chips?  The hex in the Optiloader sketch is compatible?
1229  Using Arduino / Microcontrollers / Re: Standalone Arduino 328P, Uno board as programmer on: November 03, 2011, 09:52:32 am
It says that it SHOWS the values.  Can we change them?
1230  Community / Bar Sport / Re: uController from the 1980's on: November 03, 2011, 09:06:46 am
Yes there was.  I should have said small companies that don't make much profit selling a product that only hobbyists want.
