    Spectrum analyser Equalizer project how to go about it?

    I tell a lie, I can access internet banking. I discounted it because when you add a new recipient you have to confirm through mobile telephone to authorise the new person added, but I have just thought I can ring up the bank and authorise it that way do you want to pm me your account number and...

    I find it hard to say no really but where I am, I can't use internet banking, paypal or even email, and so it's hard for me to get the postage paid to you, but thanks for the thought It's really kind of you thanks for the thought! sorry to decline!!

    Spectrum analyser Equalizer project how to go about it?

    thanks thats realy good but I wanted red especially and I wanted them mounted in a nice neat package can you buy blank packages that fit in 10 but I could maybe make an enclosure It is well worth the money saved with what you're suggesting I might have to compromise with colour but don't really...

    Spectrum analyser Equalizer project how to go about it?

    thanks for the clarification I've settled on only 15 bands now but that circuit may come in handy because I do want the single indicators to have 30 led's high ok so I'm pretty sure that I need this one https://worldradiohistory.com/UK/Electronics-Today-UK/70s/ETI-1978-06-78.pdf but I cant see...

    Spectrum analyser Equalizer project how to go about it?

    practically want the same thing as that but with the led's and controlled with external power supply and the signal from RCA jacks and so I was going to use a splitter cable so that the audio can go into the spectrum analyser and to the midi box that I have also I dont want the bar that bounces...

    Spectrum analyser Equalizer project how to go about it?

    I don't get it also a few questions: what is a filter bank how can you use a the signals from RCA (white and red) I've decided that I want the display to be rectagular eg wider than tall so I want red rectanglur led's and I want them 30 led's tall (76.2mm) and and I want 15 frequencys so width...

    Nice one for those! , Ive immersed my self in an op amp tutorial from udemy only cost a couple of quid so going to finish that then I will have a look also do you know where to buy the red led bars?

    Spectrum analyser Equalizer project how to go about it?

    I cant access email but I had a similar problem on another thread, one guy split the file with 7-zip and uploaded it through this website. it would be great if you can do that for the pdf ps he changed the extension to .txt so that he could upload! what do yo call the flat LED's in stacks I...

    Spectrum analyser Equalizer project how to go about it?

    I like that article any tips on how to make it into say 30 band spectrum and "dance" to the music? do you need to have a chip for every frequency? is there a 20 LED bar driver, because the LM3915 only supports 10, also what are the flat LED's in stacks of 10 or possibly 20 called to find and buy?

    Spectrum analyser Equalizer project how to go about it?

    I want column mode and I have read it but I shall go over it a few times how in spice do you simulate music? So I still dont understand properly it's fuzzy when zooming are there any newer pdf's that I can reference, I think I learn better when I see the same thing written in more than one way...

    Spectrum analyser Equalizer project how to go about it?

    what is linear and log? and did you say that you included the entire article in screen shots many thanks? That pretty cool especially the antiqueness of it but I dont understand it to be honest can you draw me us a spice model asy file with 32 columbs and 15 rows of red led if you have the time?

    i found this but I wanted to keep the "old skool" led look and not a screen!

    Spectrum analyser Equalizer project how to go about it?

    to include what you pointed me to with the arduino nano I have a spare mega 2560 knocking about, for more out put pins and have decided I want to run it from an interception between the line from the rca jacks (white and red) apart from that its a blank canvas!

    Spectrum analyser Equalizer project how to go about it?

    Spectrum analyser Equalizer project, how to go about it? any idea of where to start I want some led dot matrix's and recreate what old stereos used to do, with red LED's. I have arduino chips and I want to put a microphone near so it and have high pitch sounds on the right and deep bassy on the...
