META-Useful Software for DIY

[bobschwenkler]

Here's a thread link to a preamp feedback resistor calculator that I made with an Excel sheet. The thread describes its functionality in more detail.

Hi,
after having problems with AADE Filter Designer software stability, I finally came across
Microchip's great and completely free (as in freeware) active analog filter designer
'FilterLab'
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en010007

Very easy usage, Filter selection wizard, automatic circuit/schematic generation upon basic filter parameters w. SPICE data generation(!).
Filters up to 8th order can be done. Graphical display of schematic, frequency / phase plot, zoom- and printable.
Great value for free and no probs with stability under XP.

Kind regards,
Martin

The link to the symbol library at http://vacuumbrain.com is not working, it seems the domain is no more. Anyone know if it moved, and where to?

Just checked that link and found out that the PRG obviously had a major update just recently and is called "VOLTA" now:

EDIT: Volta only runs on Mac OS 10.6 (Snow Leopard)... doh.

Anyone knows a software to use with soundcard for signal sine wave generator, with dBu scale readings?

I am looking for something for calibrating compressors.

Especially with GSSL I would like to do the ratio calibration, for this I need to send a sine wave to the compressor and reading back the return. I can't do it with the normal DAW signal generator, wich obviously works in dbFS, because I want the calibration in the analog domain.

I know that there are hardware machines for such measurements, but I suppose very expensive, so a software solution would be better.

SignalSuite on OS X will do that, and it allows you to calibrate your audio output and store that calibration.

This might do the trick: (Curveros) http://2inarow.org/products.html

If you want an OSX version pm me.

Hi warpie,

how did you get Curveros up and running. I´m just getting errors because of missing files.

Cheers

Great Free software:

DIY Layout Creator
(DIYLC in short) is freeware drawing tool developed with help of a large online community of DIY electronics enthusiasts. It incorporates many ideas that came from people using older versions of the application. The goal is to provide a simple interface and enough power to let the user draw schematics, board/chassis layouts and guitar wiring diagrams quickly and without a steep learning curve. Also, it is build around the flexible open source framework that may be used to draw pretty much anything. Below is a sample board layout drawn in DIYLC3.
