Hi all, this is the place to find the latest building documents for Black Corporation's Deckard's Dream polyphonic synthesizer.
Currently, this project is at rev 1.0, PCB's are currently being released to builders. (18.Oct. 2017) and are being constructed.
A new PCB version rev. 2.1 is planned and the release is planned for July 2018, this page is only for rev.2.x
the Deckard's Dream product is available as Build to order and DIY KIT Version, both released in 2017.
Its also known or coined as the "DDRM".
The difference in the DIY KIT and assembled (Build to order) are:
Note: Although the DIY has most of the SMT devices pre-installed onto the PCBs, there are over 675 SMT decoupling capacitors (0805) and one small (SOIC8) power switch device that MUST be installed by the builder, in addition to the through hole components
A addional 1U expander is planned - release in 2018

Current BOM (last version valid 2.1.4 - Sep.2019)
Shared Mouser Basket:
(made by me - 09/2019 from 2.1.4 BOM, not checked by me - but the amount of parts looks ok)
Ultravox reply: "The cart doesn't include items that the BOM says are sourced from eBay, Small Bear, synthcube, etc."
About partsourcing: check the price for the next price break ( 3 resistors are more expensive than 10)
for EU users: order from www.TME.eu standard parts, its cheaper as mouser

make sure your OLED folow this pinout VCC-GND-SCL-SDA, very often shows the shop the correct pinout but deliver another type.
AND short the pins on the display side (where the Frontpanel is) to prevent shorts to the Frontpanel.
if you cant source the correct display (pin) use restore legs and bend they - use cable shrink tube to protect this for shorts
