Quantum Defrakulator MK2 Bill of Materials (BOM)
•
* Current Limiting Resistor for the sequencer LEDs. They share a
single resistor since there's always just one LED engaged at the
time. Use the appropriate value for your LED type.
•
I recommend using a 4.7K resistor for a diffused LED or a 15K
resistor for a clear superbright LED.
•
I recommend using multilayer ceramic capacitors for the 220nF
caps to keep the size down. For the larger values use electrolytic
capacitors as usual.
•
** LED5 is not supposed to be external. It's just part of the filter
circuit, so just mount it on the PCB on the component side like the
rest of the components. The LED type/size and colour is not critical.
Things not included in the BOM that you will also need:
1x Hammond BBDD/JJ enclosure, 1x DC jack, 1x 6.3mm mono jack for
the output, 12x knobs, 4x LED bezels (optional), 2x 3.5mm jacks
(optional, for the CV inputs)
