The next DIY modules

My next two DIY modules are simple utilities.

The two circuits in progress
I started with a passive multiple.  I called it 'bus module', somehow inspired by the CV bus from Make Noise.

Finished bus module

Nothing special here.

The jacks are cabled in parallel in two groups of four, the second one is normalled to the first one. 

Without a plug in the first jack of the B bus, the module behaves as a 1:6 multiple.  And with the plug in, the module is two 1:3 passive multiples (or two bus of 4 entries).

So if it is passive, what is the electronic circuit for ?

The small electronic circuit is used to visualize the signal that flow through the module via two LEDs, one for each group.  They are red/green LEDs, green shows the positive side of the signal, red the negative side.  I got that idea from the Make Noise's CV bus.  The implementation is inspired from Mutable Instrument's Links.



The second module will be the subject of the next post.

In the mean time, let's see if the beast is alive...
