That’s not an official guide.
It’s more an best practice guide, you find infos about the firmware/software on the main page: KIJIMI Documentation
Sourcing parts, order higher quantities to get the best price and more parts for free or for a better condition than ordering later single parts and you have spares (tactile switch, encoder, potentiometer, opamps 3340,3360)
Sort all parts, one carton with resistors, one for capacitors...one for mechanical parts, one for Ics/semis.
Sort the values like 1R-999R, 1K-9.9K, 10K-99K.... same for capacitors
Start with the mainboard and hardwareboard and next Breakoutboard and PSU.. so you left less plastic bags for the voices which makes things easier
Use lead based solder core or you get trouble with the ground pads and in case of failure or wrong part placements it’s more complicated to desolder the part.
Use for the voice cards a mounting frame which costs 50-250€.
You have to respect the Known Issues/current Error List on this page - when you build an Kijimi, install at the beginning the Sub Osc Fix - and fill the holes of the resistors which you don't need anymore or use an edding pen and strikethrough the resistor numbers on the pcb.
BOM:
new BOM from July 2019 with improved Sound, i renamed the File because Roman used the same Filename as before which can confuse and ends in mistakes when you open accidentally an older file with same name.
BOM from 23.July 2019
KIJIMI-BOM-REV1.01_DSLMANxlsx.xlsx
please add 16x 1M resistors for the SUB OSC FIX
the Difference between first (v1.02) and latest BOM (xxx_DSLmanxlsx.) which improve the sound:
MOUSER Basket: (imported from above xls) (updated 28.May 05:40PM GMT+1) updated see issue list 1.June.2019 this BOM doesnt match with the SUB OSC fix and addional Panned Voice Outputs (there´s a separate Mouser project for the MOD)
https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=6285be713e
the mouser project was improved for more parts - same price, the quantity is noted as "customer note" on each bag.
Voicecard change - must be used in your build !
replace R108 from 10K to 20K
replace R111, R52 from 91K to 20K
replace R38, R97 from 330K to 576K (i used a 560K plus a 20K resistor in series which was measured to 575k (1% resistors) (only 576K when you want TL074 for IC2 and IC9 otherwise use 330k)
remove R60 , R119 (220R) → not installed
replace IC2 and IC9 from TL064 to TL074

VOICE BOM ssi2140 Version
please note, this BOM only contains the the new ssi2140 Voicecard PCB parts
Mouser BOM: https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=c757799ef6
(without ssi2140,AS3360,AS3340 available from: http://www.soundsemiconductor.com/buy.html
Attention
you have to change on the Mainboard one resistor as described in the above KIJIMI-VOICE-BOM-REV2.
this change the output Gain - the new cards are quiter than the old ssi2144 cards.
C61 on the Voicecard is 1nF film instead of C62
Total costs of Material:
Don´t miss the Frontpanel and case from DIYHUB http://siddarthianinnovations.bigcartel.com/
please respect your local requirements/laws for a powersupply (110V AC/ 230V AC) and
doublecheck the power input jack polarity (inside +) and
the diameter of 2.1mm or 2.5mm of the plug/jack or you learn it in the hard way
Modification
check out this page Kijimi Modifications
Powersuply Warning
don't mix the external PSU bricks or you destroy your Device.
The Kijimi use a 24V DC PSU
