Diy Drum machine?

[the3secondrule]

I'm after something not-overly-complicated, that I can build in a big box with maybe arcade style buttons, for my toddler to jam on 

Not overly fussed on sound quality, sequenceability, midi or anything modular (I am barely managing to withstand disappearing down that rabbit hole as it is). Just something standalone that will make vaguely drum-ish noises when plugged into an amp

thoughts?

Have a peep on e-m's DIY subforum, lots of drum stuff on there. More will be in the Layout Factory and Developers Corner.

EHX Sonic Boomer (simplest option) or Space Drum could be good, you just need to make a little pad surface that he can hit to put an electret mic under and then there's knobs to play with too.

Just checked a couple of demos. The super space drum looks like awesome fun!
Maybe a few of those old EHX percussion boxes could be the way too go. I'm guessing the schematic i saw with your name on it is verified, scruffie?

They're direct copies of the original factory schematic so they may not be correct in all cases but the super space drum one is, on DIYstompboxes someone converted it to LM13600... I think I still have the Eagle files for his PCB layout.

The sonic boomer is also verified, there's a project for it over at topopiccione.

I'd be really keen to grab the eagle files if you do? The super space drum looks pretty amazing
Even just the schematic, if you weren't comfortable to share the layout...
Cheers,
