Caught my eye so I looked to see what it is: This DSP Musicolour accepts audio input signals and drives coloured lights "in tune" with the music. Its four output channels respond to different audio frequency bands and the brightness of the lights is in direct proportion to the amplitude of the frequency components. A dot-matrix LED menu display is featured on the front panel and this also functions as a spectrum analyser or VU meter.
Main Features
Full digital design using a DSP microcontroller (dsPIC)
Powered from 230-240VAC or 115-120VAC mains with auto-detection of mains frequency
Four phase-controlled output channels (8-bit resolution)
Optocoupled Triac triggering for complete isolation of control circuitry from output circuitry
Zero voltage switching of Triacs for minimum RF interference
Four mains outputs rated at 800W each (240VAC) or 400W (120VAC)
Selectable gain plus selectable minimum and maximum frequencies for each output channel
Selectable filament preheat current for each output channel
Persistent software settings
Self-diagnostics
Chaser modes
Direct stereo inputs for audio modulation of lights
Microphone input/third channel input for audio modulation of lights
7x15 pixel dot-matrix LED display for menus
Dot-matrix display can function as a spectrum analyser, screen saver or VU meter
Software-controlled input selection with software mixing
Adaptive potentiometer control for software settings
Optional provision for ICSP (in-circuit serial programming)
I especially loved this: Special Offer Buy issue 150 (March 2001) to issue 207 (December 2005). $278.00 $278 for one fifty eight magazine(s) sure is special! |

It's a great magazine and one of the few left. There aren't many of us who build things at home anymore, so they need to charge a bit more to pay their salaries. Your posting should generate subscriptions for them, not slam their pricing for trying to stay in business.
It actually is special and I hope it, Circuit Cellar, and Elektor never go away like several hobbyist electronics magazines already have.

I misread their page, so have corrected my post. You get fifty eigth magazines for the $278; that's under five bucks a magazine and quite fair. I better learn to pay more attention. |

We're not magicians here. The firmware is not posted, so I don't know why you are asking for something that does not exist as a separate item from the microcontroller.
From the sounds of the article (you had me curious with all the whining, so I spent a half hour looking at everything myself to help you out), it looks to me like you have to buy the micro pre-programmed, which is a way for the author to protect the extensive code he wrote (yeah, people spend a lot of time writing and debugging these - the last thing they want is someone mass producing their stuff without a royalty).....the BOM lists the micro as "programmed with" versus just the listing the chip P/N and then having a link to the firmware. Google knows NOTHING about that firmware's code number, so I think you are SOL on getting it for free.
I bet he also programmed the anti-copy fuses as well, so you can only build ONE per chip you buy. In a way, he has his royalty built in, as I'm sure you want to build a few hundred of these disco lights to make yourself some money. Now you have a partner, someone who did all the work for you, and you should pay him accordingly, fairly, and with a smile and gratitude each time you sell a box.
One more thing - don't get yourself or anyone else killed as this thing runs off the mains supply, making it extremely dangerous......

My apologies to all people here for the post and the confusion caused.
I had posted all the 4 parts of the article because another member asked me in a private message to scan it for him. I decided to share it with all the members instead of just sent to this friend only.
The firmare-software is not available anywhere and my mistake is that I haven't checked it before posting the article for all people.
My apologies to all.

I don't know why you are apologizing. It's a cool article and shows how far we've gotten since I built one of these, back when the Intel 4004 was a mere pup.
It's just that some people assume EVERYTHING is freely available and they think if they become big enough pests, someone will pirate things for them.
This one looks like it has everything available to make a project, just that you have to buy the micro preprogrammed, which is great for those who don't know how to write code or don't have DSP programmer.

Mr. pl4tonas
there is no need to apologizing instead of it's a good post and we need to give thanks to you
Mr.solutions is right
it is never necessory that everything is freely available .
but when we look one article then we just assume that all stuff will be available just for save our time
rather we should think this as a good idea to implement our own.
so i want to give thank you to post such a nice article

this is interesting but i couldn't ffind the source code
and also not available on silicon chip website
please upload it also The same project "DSP Multicolour" from Silicon Chip magazine is re-published in EPE magazine May2010 issue and only the hex file is available on EPE server for download. Cheers |
