| 30 Aug. 2022 | BOM - Voices | ERROR | the Trimmer Mouser part number is invalid | Line 180: 652-3296X-1-103RLF | BOM update needed | -- | |
| 30. Aug 2022 | BOM - Mainboard | INFO | the 220uF caps on Mainboard are BI-POLAR - | respect the BOM partnumber | |||
| 07 Sep. 2022 | Controlboard | BUG | there's no Pinout described on the Controlboard for the OLED - wait on info from Roman (should be the same as in DDRM/KIJIMI | please read carefully the next INFO section |
Important INFOs before you start the assembling
Date | Location | Type | Issue | Tip |
|---|---|---|---|---|
| 13. Aug.2022 | Controlboard | INFO | minimize Slider/Potentiometer malfunctions Soldering Info | when you install the sliders, DO NOT solder all pins successively, solder only one pin at top and bottom and go to the next slider, when you have all installed - solder the next single pin at each slider. this have to respected on Potentiometers too. The Sliders and Potentiometers have lubrication inside which is sensitiv for heat and can be easily damaged (was happen on many Syncussion clones ) |
| 13. Aug.2022 | Controlboard | INFO | OLED Selection and R101/R32 - R100/R102 | when you have an OLED with the PINOUT: VCC-GND-SCL-SDA install R100 and R102 (0 Ohm - a bridge) (R32/R101 must be empty) in case you have an OLED with the PINOUT: GND-VCC-SCL-SDA install R101 and R32 (0 Ohm -a bridge) |
| 13. Aug. 2022 | All pcbs | INFO | some IC Sockets are not in the same direction, it´s an known issue that people install an IC backwards | Double and triple check every IC orientation - maybe 80% of all device malfunctions was occurred by this and can end in a very expensive repair |
| 13. Aug.2022 | Controlboard, PSU, Mainboard | INFO | the LEDs do not work | when you build the device - its important to start with the power supply - here you can test the LED orientation. never trust the vendor pinout for LEDs. normally is the long LED leg the positive end (anode) (but some circuits are powered from negative rails and GND is the positive end in this case- just saying - to explain it) |
