Hi, can you share the code?

The code is not published because it is the copyrighted work of a book.

Love how the look.... but unfortunately flexible filament LEDs have a huge current pull which can tax the module or the power supply. works great for gates and triggers!

Hi all. My arduino nano does not have ports D14,D15,D16 etc etc. Should the D not be A?? Please correct the schematic. Thanks.
@HAGIWO 17 сағат бұрын
The Arduino nano should have pin D14; it has a function assigned to the same pin as pin A0. edistechlab.com/arduino-nano-pin-out/?v=55add3d845bf

Can this be made with a standard RP2040 found on AliExpress?
@HAGIWO 17 сағат бұрын
XIAO RP2040 is recommended. This is because the number of ADC pins is insufficient for a typical raspberry pi pico.

Hi guys. My Oled display has 4 pins, gnd,vcc,scl and sda. The one in the video has 7 pins. Uhm confusion hits me... any advice?
@HAGIWO 17 сағат бұрын
I think the communication method is different between I2C and SPI. you need to use SPI type (7pin) OLED.

Hi, I'm working on this build now, and digging into the code a bit to understand it. Can you show how you calculated the variable voctpow in the arduino code? I'm planning on adapting it to hz/volt to work with my ms-20.
@HAGIWO 21 күн бұрын
Please check below document. note.com/solder_state/n/nd2c22a73e8fe f = f0 * 2^(5*LSB/1024) This formula is used.
@safetybreakroc 20 күн бұрын
@@HAGIWO thanks very much, missed this section somehow. For anyone else trying this, the equation for hz/volt is just linear. There should be enough room in the flash to add both sets of coefficients and make it switchable between them if anyone has this use case. I believe this is correct: =((CV)*(highest frequency-lowest frequency)/1024)+lowest frequency.

@ComminuoFascis Ай бұрын
Hey, love this design. I was looking for something simple like this! Quick question, why are the TL074 power pins reversed on the schematic? Pin 4 (+12V) goes to the negative rail and pin 11 (-12V) goes to the positive rail. No worries if you don't have the time to answer, thanks for everything you do for DIY modular!

Thank you for letting me know! It was a mistake in the schematic. I’ll correct it right away.
@LeanderSeige Ай бұрын
First of all: thanks for sharing! I was looking for something like this for quite a while. One question: U1C, U1D and U2 seem to work just as buffers with 1:1 (no) amplification. Running them as voltage followers would have the same effect and eliminate 8 resistors. Wouldn't it?
@HAGIWO Ай бұрын
Yes, that’s correct. Using them as voltage followers would eliminate the need for resistors. The input op-amp inverts the phase, so I used inverting amplifiers to invert the phase back. However, since phase inversion doesn’t cause any significant issues, you can definitely replace them with voltage followers.

@mutedsounds2k Ай бұрын
It reminds me the Doepfer A-139-2 "Headphone Amplifier". Even the size (6HP) is the same. But that one uses 2 power transistors, instead. I suppose it's because headphones require a higher signal level.

@HAGIWO Yes, I have this library installed. And the Encoder.h and MCP4725 library. I have the same red DAC. The Encoder I am trying it one with no board, but 3 pins on one side and 2 on the other side. I now have the "working " button, pressing once, and it toggles the little triangle on and off.
