Attention, this guide is only for the psycox Version SY-1M , the main difference on this Version is the addional Midi function, Matched SMD Transistors and improved powersupply.
check my SY-1 page for the thehumancomparator version.

my addional build tipps:
- the first provided BOM was wrong, the included FLAT pushbutton (this ~7mm height switches aren´t needed), the correct 2 pushbutton switches (~12mm height ) are included for the first batch. (ordered until April 2018)
- the groundpads are not easy to solder, i prefer to use leadfree soldercore for this pads (clean this pcb sections after soldering)
Power Input
the BOM use a 2,5mm middle Pin powerconnector BUT the most powersupplys use a 2.1mm middle pin, you can´t use a 2.1mm powersupply with a 2.5mm connector.
the most webshops have more 2.1mm powersupplys in stock and 2.1mm is the defacto standard.
middlepin is +
Spec: DC 7.5V output with 300mA or more
Pinheader assembly
- solder one the pin header to the pcb
- shorten the pin stripes by 1mm-2mm
- plug the pin stripes in the hader, it has to be full in it - like this:
- now attach on the top a further pinheaderlike this: (the same is on the right side with the 3pin header, the 4pin header dont must be shorten because the header don´t have the same height.
before you solder the pinheaders to the top pcb
make sure the pcb is flat and do not bend.
make sure you solder the MIDI channnel switch, midi input jack and power input to the bottom side like :
if you have everything soldered and you´re ready for the first test, make sure all IC´s and THT Trannys have the correct orientation, dont install the ATMEGA for the first test
please doublecheck the polarity of your powersupply, middle pin is +
set the powerswitch to off,
connect the powersupply
