DDS and the Electronic Music Box - April 2012

First, I very much enjoyed the article on DDS by Craig Lindlay. I do have a question, mainly to make sure I'm understanding DDS process. If, as in the example, M is set to 295,279,002, and the sample frequency is as given at 32Khz, and also as given, I have a wave table with 256 entries (2^8), and I...

Re: Small Fan with Flap?

Hey - Great to have all the suggestions!<p>I just received a shipment of a car automatic electric door lock opener for $1.98 from a place in Tampa. Hope to get to try it out soon. It's the right price, appears to have enough 'umph' to open flappers. Not sure yet that it will stay in one position aft...

Re: Small Fan with Flap?

Hey! Thanks for all the ideas! Some comments:<p>Re the Bathroom fan: good idea, but it's too large. The amount of air required to lift the fan would turn the smoker into a blast furnas! <p>Re air regulator flapper: Have tried to locate different dashboard components in the past, but found them all t...

Re: Long Interval Clock and/or Timer Needed

Yea, that's a good idea - something along those lines is a 'Lock Box' similar to the one that Realtors use on houses that are for sale. Ace Hardware sells them for general use (we have one for the cleaning service that comes to our house) at around $20. They let you change the code to whatever you w...

Re: Embedded Email Client

Sunil, I would suggest also going over to a site like http://www.avrfreaks.org/. They deal with a lot of software issues for micro controllers.

Small Fan with Flap?

As part of the project that I'm building - a BBQ Smoker Combustion Chamber Controller - I need to be able to turn on and off a small fan that pushes air into the combustion chamber - around two (2) inches in diameter. This has been built, and works great - some fine NC style BBQ is being produced - ...

Mentoring near Alpharetta, GA

I've developed a controller using a AVR uProcessor. I use it to read thermocouples, and control an air-supply valve to my BBQ Smoker. It communicates to a web server front end via RS232.<p>It's currently all hard-wired, connected to a prototype board. <p>I've used some software to design a PCB board...
