[ $5 ] DIY eurorack modular synth KICK (Roland TR-808/909 drum machine type) with arduino

[@UnauthorisedService]

Built and in my rack ... many thanks for sharing your work! 👌

[@nbuehster]

I didn't think about this until now, but there needs to be special holidays for producers/DJs. In this case, they would be August 8th and September 9th.

[@spacedudejr]

I get it

[@romanopekushin3099]

Good features, easy management and implementation. You feel and see the final device very subtly. I really like your work. I have repeated some and am very pleased with the result. Thank you so much for your publications.

[@sCealt]

awesome :)) btw you can get 16 bit pwm out by doing some tweaks in the register.

[@YourModulesMayVary]

I was unable to get sound out until I removed the output resistors/caps. Sounds great to me just coming out of D10 with the diodes. thanks Hagiwo!

[@YourModulesMayVary]

scrap that, I must have done something wrong :-) working great now as per schematic! much smoother with the output filtering

[@hughman8597]

Amazing ! Nothing more to say ! Greetings from germany. THOGRE

[@MrGuillermofrancisco]

you do it again my Hero!!! congratulations

[@constantine333B]

Have you built any drum modules that include an 808 style accent function? Could one be added to this programmatically through a simple diode clamped gate in? Thank you!

[@earentech]

This is awesome! Thank you for your work and inspiration, all of your projects are really great🔥 I actually built this one and I love it, but it sounds not exactly as yours😔 your kick sounds “fat”, mine more thin, and I don’t know why. It happens on breadboard and after assemble, I even tried two different arduino. And mine in some positions create little 8-bit style sounds😬

[@HAGIWO]

Maybe the harmonic noise is not being attenuated, check the constant of the CR low-pass filter.

[@pieterjanvandenberge]

Thanks for sharing! :) I've build this one with a friend. Sounds very nice but the output is very quiet. Is there a way to fix this?

[@HAGIWO]

It is recommended to use VCA etc. to amplify the voltage about twice. If the sound is still quiet, the part constants may be incorrect.

[@chrisroots9771]

build an LM386 audio amplifier and put it at the output of the Arduino. This is the way!

[@livingrainman]

Love your videos! Will this code work on a pico?

[@МаксБургер-ж7я]

Hi, thanks for your module idea! I trying make your module. When i dowload sketch to arduino, i get message "warning: narrowing conversion of '-35' from 'int' to 'word {aka unsigned int}' inside { } [-Wnarrowing]' . It belongs to any number with minus in code. Maybe you have any idea about this?

[@interpr3t]

Awesome

[@normdurkin6425]

..excellent

[@hakank3841]

hello great! can you add some diagram for connecting kits?

[@HAGIWO]

I'm not preparing the diagram because I'm spending time developing new modules. Since the number of parts is small, I think it's easier than you think.

[@cookseyyy]

I just put this together on a breadboard but the output volume is super low. Has anyone else had an issue like this?

[@HAGIWO]

Check out the circuitry around the Arduino D10.

[@danielmendes5682]

excellent job!! could i use zener diodes instead of the schottky ones?

[@HAGIWO]

Thanks! It can be replaced with a Zener diode as a countermeasure against overvoltage. It is recommended to leave the Schottky barrier diode on the GND side as a countermeasure against negative voltage.

[@erikbartmann]

Do you have informations in English for your great projects? Love it!

[@HAGIWO]

Will you use Google Translate? There is no important information in my documentation. (The schematic and source code are important.)Thank you!

[@Oldunlock]

22 op on your shematic is 22 picofarad? Nice job!!!

[@HAGIWO]

it is 220 pico F. thx!

[@unrandom229]

Hey , What do you use to power your rack?

[@warpigs330]

How are you doing the audio output?

[@HAGIWO]

USE arduino PWM output changing duty rate.

[@warpigs330]

@@HAGIWO Are you using a low pass filter to use it like a dac or using raw square waves?
