Fixed an issue with our contact form

Just making sure people know that we were not ignoring you, there was an issue with the contact form which was set up for the old name and old email.  We will be going through older emails and contacting people, sorry for the hassle.

DIY kits now on sale

Just in time for you to get yourself a holiday gift the SPECTRA MIRROR is now available in DIY options. We have also lowered the prices on our older DIY kits for the VERT and SWITCHES expander. Heat up that soldering iron to stay warm this winter!

Spectra Mirror DIY options now available.

At long last here is the build documentation and BOM required to support a DIY build of the Spectra Mirror.  The entire build is through hole with easy to find parts, there is one optional SMD matched transistor pair for those wanting superior tracking of the internal VCO.  I would say that this project is not for a complete beginner but would be quite easy for anyone with a fair amount of DIY experience.  The calibration procedure requires at least a multimeter and benefits from the use of an oscilloscope, although again this is not crucial.  Please read the build documentation if you want a better idea of the level of difficulty for the build.

Build documentation is here.

Support/ discussion thread is here.

Mouser BOM is here.  A few parts have to be bought from other places as listed below:

100K B metal shaft potentiometers x 7 : several options exist

100k B plastic shaft potentiometer x 3 : you want to buy the "tall trimmer" from song huei as others do not stick very far out of the panel.  Plus these pots have a painted indicator.

"Erthenvar" PJ301-B style jacks x 12 : be sure to buy matching washers

Knobs x 7 : You can buy whichever knobs you like but this is the source for the purple ones that I use.  If anyone knows a European distributor for these knobs let me know and I will add them to this list.  Color option is violet

Large knob x 1.  If you are using other knobs I still suggest using a large knob for this dial.  Again color is violet.


The following parts will be needed.  I am specifically making you source them as a "barrier for entry" as doing this matched transistor pair is not for DIY beginners.  SMD soldering aptitude is required.

Transistor pair is by diodes incorporated part # ZXTC2045E6TA

You will also need a 22k resistor and a 22nF capacitor.

Spectra Mirror patch examples

Over the past couple of weeks we have uploaded some videos detailing different patch examples to get you started with the SPECTRA MIRROR.  Here is a repository for those videos as well as any that will come out in the future.  If you would like to share a patch you have made with the SPECTRA MIRROR please contact us and we may add it to the list!

If you are in New York this weekend please come by and check out our booth at Machines in Music.  We will have all new diffraction glasses to give out and all of our modules to demo.  Our booth will be the colorful one.  In other news the Spectra Mirror and Switches assembled units are both sold out, but don't worry!  We recently restocked with Foxtone, Control, and sent units to Perfect Circuit as well.  More stock is on the way as well as DIY options for the Spectra Mirror.  See you at Machines in Music!
