  • Page 1 De-Generator DIY sample synthesizer Building instruction 1, the panelboard V1.02 english stand 08.04.2019 www.tubeohm.com...
  • Page 2 We try to write the DIY manual as detailed as possible. If you have any questions, please contact us at Kontakt@TubeOhm.com If you can't get on with a component, let it go first, clarify the situation with us, and then you can move on.
  • Page 3 It's better to ask once than to search for errors for hours afterwards. I can understand that you want the de-generator to be finished quickly, but if you work too fast you make mistakes very quickly.

UB = operating voltage 3,3 Volt U_led= voltage of the LED I_led= current of the LED R_vor= value of the resistor in Ohm R_vor=(UB-U_led)/I_led. Sample calculation for 4 LED's red . U_LED=1,6 Volt I_LED =5 mA R_vor =?
  • Page 5 All right, let's get started. Is your soldering iron hot? The following procedure. First come the resistors / coil, then the capacitors, then the IC sockets, then the LEDs, then the potentiometers and encoders, switches, connectors and the mic and finally the LCD display.

  • Page 10 Now we come to the IC sockets We need : 3x14 pin = for IC 7,8,9 =74HC14 4x16 pin = for IC 3=74HC165, IC4=74HC165, IC5=74HC165, IC6=74HC595 1x20 pin = for IC 1=73HC573 Attention, the IC sockets are marked. Please solder the sockets right around into the board.
  • Page 11 The buttons in the De-Generator The buttons have a flattened side. This is also marked on the board. They must be installed in such a way that the markings point to the left ! 1:) 2x white with red LED...
  • Page 12 Now the five buttons of the pages are soldered in The encoders The De-Generator uses longlive encoders with 100,000 switching cycles. 1x PEC11L4120F-S0020 This is the Page Encoder and has an additional button. This encoder has five connections 4x PEC11L-4120F-N0020 these encoders are without pushbutton and are installed in the positions ENC 2,3,4,5.

  • Page 18 K14, the volume connector connects the volume control to the audio signal It is also pushed through the holes from the back and soldered from above. K3,K4 is the connection to the CPU board and should look like this The Micro Farbcode/colorcode/code Value/Position 1xMicro...
  • Page 19 So, all soldered together? Soon it will be done. Before we solder in the display we do a quality control. The board should now look like this from below Tip: So, for example, I don't feel like troubleshooting for hours, so I clean up I'll take a look at all the solder joints with a magnifying glass.
  • Page 20 The LCD Display Screws and nuts Farbcode/colorcode/code Value/Position 2x M2,5 screw 4x M2,5 nuts 2x plastik washer Both screws are inserted into the rear holes and secured with the nuts. A plastic washer is placed on each nut. The plastic washer prevents the metal nut from being damaged. short-circuits on the board.
  • Page 21 Now insert the display into the board and fix it with the remaining two nuts. Now the board should look like this: When everything is straight and screwed on, the display can now be soldered to the board. It is best to solder first one row of the connector and then the second row.
