DuaLFO Now Available

The first (short) run of DuaLFOs is complete and ready to ship.  Get'em while they're hot!

Auxiliary LFO Equally Slow

Last night I ran the same tests on the Auxiliary LFO.  It has the same maximum frequency of 46Hz, but if anything it is slightly slower than the Main LFO.  I recorded a run of 1 hour 35 minutes.

I think that's slow enough....

Main LFO Goes Slow

Last night I finally characterised the frequency range of the Main LFO of the DuaLFO.  And it is quite a range!  Highest frequency was 46Hz.  Pretty good.  The lowest frequency?  Well, probably better to think of the period rather than frequency.  In this case I measured the period to be 1 hour 25 minutes.  Or, in frequency terms, that's 196 micro-Hertz!

SSssssssllllllloooooowwwwwww...................

Next is the Auxiliary LFO, but I'm guessing that it will have similar performance.

DuaLFO #1 Comes Alive

At long last, and after a couple of minor PCB mods (ahem....) the first DuaLFO is completed, tested, and fully operational:

As you can see this first run of modules is using the Cliff KM15B knobs, and in practice they look and feel great.  The SYNC pos/neg edge button has a nice red Rean cap, and the bicolour LEDs sit nicely in the panel.  I think the graphics worked out well too - the MetalPhoto finish is very crisp.

This is an 18HP panel, offering comfortably spaced controls, jacks and indicators.  While I can understand the benefits of squeezing modules into tiny panels to get a lot of functionality into a small space, it actually takes a lot of skill to design a small panel well.  The best examples of this I know of are the Tektronix 7000-series scope and TM500-series test equipment plugin modules.

The last task to do before these modules are ready to ship is to finish the user manual and get it printed.  If that works out as well as the panels then I think its going to look quite good.
