Well, of course... the fact is that I already have a 16V cap and I wouldn't make an order just for one cap XD
Thank you however

thanks.

Yes, provided you don't need MegaDrum firmware versions past 20100516. But since you could not figure it out yourself I think you will have a lot of troubles building MegaDrum.

thanks for answer. actually, I am experienced DIY hobyist, but I've noticed, that there is atmega32A - with A
cheaper variant of 32. So I assume, my previous posted atmega is right

As dmitiri stated above, you will need to have the atmega chip programmed by dmitri to get the latest firmware updates. He has the chips on hand to program for you, you just have to pay for shipping and a small handling fee. I highly recommend going this route because dmitri has been able to solve many users issues by providing custom firmware updates specifically dealing with their problem.

Also he provides Atmega 644 which will provide more storage than the now outdated Atmega32 he used to incorporate into his builds.

PM dmitri to find out more about how to order from him.

I certainly will. but now I'm Out of $ and need some drum sounds

Hello all,

Sorry to ask this but does someone have a PDF of DOC file or something with the last version of the PCB, components list and firmware version to build the 32 inputs version?

This is a very long post and and don't want to mess up with the construction

Thanks a lot!

Diego.

synthex, why in schematics there is C3 and C4 100nF, and in pcb top board there is 1uF and 100nF (around inductor) ?
I do not know which to place in my pcb

[dmitri]

synthex, why ...

Look at the Synthex's profile. See when he logged in the forum and posted anything last time.
