Here starts my own Building Documentation /Steps and Modification.

Dokumentation: http://thehumancomparator.net/building/

pdf. Dokumentaion :

Schematic: TTSH-schematics.pdf

STATUS pcb finished, all fader mounted - ready for calibration

ATTENTION -  wiring from PSU to the module headers are wrong "silkreen error"  +/-  must crossed - doublecheck before power up modules


please read the Buildings tips to save time

and get faders/jacks in correct orientation/way

dont solder switches, pushbutton, faders and jacks prior finally assembly - the orientation is only correct by placing all jacks/faders..


Result from Widy:

BOM Failure - parts not listed
----------------------------------------
1x BC558b S&H  missing ( need 9 ..  BOM say 8)
1x 150K S&H fehlt ( not in building doc)
1x100p fehlt mir einer ( missing part )
 
parts left after build from widy:
------------------------
1x15K
1x47K
1x1M2
2x100N Keramik
1x3p3 Keramik
parts left LED-man /DSL-man
------------------
1x 47K

first TTSH Kit arrived on 05.03.2014


TIP:  check the pcb for failures !




Starts soldering the VCO Boards:

Online building documentation failure:

for VCO pcbs in zthees building website shows 1x61k9  but needed on each pcb 2x 61k9 resistors

http://thehumancomparator.net/4027-2/


  


Start assembly Main PCB

Use standoffs/Spacers:

Mounting VCO-1 pcb with long headers, but solder before 150K & 3m3

( i use only long headers)

  



PSU with DC-DC Voltage "regulator"

right picture shows the X-crossed ferrite bead to fix the -15/+15V  silkscreen error

    


VCO testing - wiring a +15v cable to resistor and probe ..

see my solution..

  


VCF picture - handle with care -  2n3904/06 - BC558 doublecheck the position near Tempco 2h

  


AR/ADSR

 

VCA

for testing: test with probe a VCO (need +15V cable see VCO testing above)

feed the VCO signal to the VCA and check the waveform with a oscilloscope.

            

 

Ringmod, Preamp, Envelope Follower

 

Mixer


 

 

  

Noise, Voltage Processor

 

 

 

   

 

first Panel mounting test

 

S/H - Clock - Noise

 

 

 

 

All Parts soldered, Panel mounted, need to solder the jacks.

Building tip:

place each row of faders on PCB and solder 2 pins, place the Panel in right way and mount all screws,-- solder the faders complete.

remove the panel and plug all jacks in position, place the panel - mount all screws and few jacks with screws - turn the device, solder the jacks.

solder the LED at last.
