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 was released end of 2018, this page is only for rev.1.x the REV.2.0 guide is here DDRM rev.2 guide |
| Info |
|---|
Product Info: 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 componentsA addional 1U expander is planned - more later in a addional page Examples of Presets and voices: https://soundcloud.com/deckardsdream |

Current BOM 1.10 from 08.Jan.2017 (still valid in04/2019)
...
for EU users: order from www.TME.eu standard parts, its cheaper as mouser
Display:
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.

REV1.1.0 CORRECTED THE AMOUNT OF DIP16 SOCKETS REV1.0.9 TL074 CHANGED TO TL064, TL072 CHANGED TO TL062. HEAT SINK, THERMAL PAD, COOLING FAN AND MOUNTING HARDWARE ARE OPTIONAL IF TL06X OPAMPS ARE USED. VOLUME KNOB AND SLIDER CAPS PART# CHANGED. REV1.0.8 CHANGED C12 TO 1uF, C13 TO 330uF ON THE PSU BOARD REV1.0.7 CHANGED R2 ON THE OUTPUT BOARD TO 22R, CHANGED C6 ON THE MOTHERBOARD TO 10uF REV1.0.6 CHANGED 1N5817 TO BAT85S ON THE MOTHERBOARD REV1.0.5 ADDED USB A TO USB B ADAPTER REV1.0.4 CORRECTED 30K MOUSER PART # IN A VOICE CARD REV1.0.3 CHANGED HEAT SINK QUANTITY, C2 ON OUTPUT BOARD IS 100uF NOW REV1.0.2: ADDED ST LINK PROGRAMMER |

| title | Alfa 3340 |

According to Alfa, i spread the good new: After some common work last week with them on DD and AS3340, We can officially announce that Deckard is happy with theses chips 
Here are the values to update :
- FM input (initial current - solve the corrupted calibration) : R6/R112 to 390k
- 12V adaptation (supply current to internal 3340 Zener) : R39/R145 to 560r
- PWM Comparator output (minimize pwm control on frequency) : R22/R128 to 51k
please note, this parts are not present in the BOM and guides !

Official Build Guide: http://www.deckardsdream.com/build
Voice Card Assembly Document. This was created by Lysandre Follet, and has been tested as correct by a couple builders.
| Warning |
|---|
some users reported that the board doesn´t fit in the case - the mainboard pcb is too big.. on the mainboard is on top and bottom a small 3-4mm pcb stripe, that need´s to be removed. |
Build Tips
prepare BOM and Parts:
modify the BOM, change it to single sheets (tabs) instead in one list or you can easily scroll in the long list to the wrong board (like motherboard instead control board)
when you have received the parts, prepare different boxes (resistors, capacitors, ICs, hardware)
sort the bags to values like 1R-9,99K 1K-9.99K 10K-100K and so on.. same for capacitors.
start on the boards with the most used values like 499R
this speed up your build
measure one part from each bag and label the bag like "T" for tested.
check the BOM for the quantity for the board and count each value, drop it in a small box or put the secure on your desk before you install.
OLED Display:
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
Troubleshooting
a lot of users reported problems with slider calibration or display failures, auto tune.
the most issues are from a faulty ARM chip, this can easily happen by:
wrong component values on motherboard and Controlboard, shorted 3.3V power.
a short connection from 3.3V to ground or (12V/5V/-12V) is enough to kill a function in your ARM Chip.
Q: what can you do in case of failure ??
A: read and understand the schematics and double check the BOM against your parts (there are few different values between BOM and Schematic) the latest BOM (see above) is correct not the schematics !

some users plugged the powersupply in a voicecard slot and earn a damaged ARM processor. to minimize this risk, few solutions: put a tape on the voicecard slots 2-8 or use a cable tie to shorten/bind the powercable between powersupply and breakoutboard as short as possible (you can´t attach the powersupply furthermore in a voicecard slot) |
| Tip |
|---|
when you have trouble with your voicecards like a whistle on upper or lower card or wrong VCF... the calibration process is not perfect, swap this "faulty" voicecard with another card and run the calibration for the single voicecard not for all. if everything wents wrong: insert only one voicecard in Slot1, run calibration (not the tune function). when everything is fine, add the second card to slot 2 and run again calibration - on slot 2, insert card 3 and so on.. |
