In this video I turn the circuit board from an old toy into an eurorack drum module.
Thanks to Spenny for letting me use some of his footage in the video!

This is exactly the kind of video I needed to see in order to wrap my head around a bunch of stalled projects. This is great, please do more videos! I’m curious about that DIY filter you have in the eurorack too.

The filter is my stripboard version of Kassutronics' KS-20 filter. If you want to build one you can find the stripboard layout on my website: sandelinos.com/diy/ks-20-filter

Very nice! I did a bunch of circuit-bending like a decade ago, and got into diy eurorack stuff this last year, and this seems like a very straightforward way to merge the two. A lot of devices have a playback speed resistor that can be replaced with a potentiometer, but if it's actually part of voltage divider it might be very easy to add CV. Even if not, a vactrol could do the job, too, if a little less cleanly. Those animal noises often get really interesting at low speeds.
Nicely done! Especially liked the work you did cutting everything down to what looks like 8HP? Brilliant!
That Sony looks like it was a pretty cool toy back in the day. Your hack made for a very usable module, lofi drums and crazy sounds. Love it!
Great work and a really cool project! 😊👍
Wow great explanation, really enjoyed from start to end, you did some awesome job there!
Really cool to watch you build this. Awesome video!
This was awesome to watch and so cool. Wish I had your electronic smarts. Brilliant adaptation!
Excellent video love how you show the process for creating the schematic really useful!!
My god, that's badass! Congrats!
Great tutorial. Cool project! 👍
Just, WOW! So much time and energy involved. While easily duplicated with readily available drum machines, I'm forever in awe of those who can create their own stuff. Kudos!
Great video, thanks.
You’re a master at this!
A real life wizard ! Very interesting to watch. 👍
Cleverly done and demonstrated. subbed
So cool! There are tons of musical toys that should be able to modify and adjust to make into synth modules.
Very nice 👌
Great job
Good job !
Look, mum! It meows! And no computer. Nice project :)

your knowledge is impressive, nice one!
You got my sub. Keep this crazy shit coming. You have the funnies working for ya
Great little projekt and great execution! :) For drilling larger round holes in thin plates I can highly reccommend step drills, they leave almost perfectly round holes compared to regular twist drills which have a tendency to make tribular shaped holes aswell as grapping the thin sheet metal. Moreso when hand drilling those holes.

Thanks for the recommendation!
Love the animal noises option. Good job!
Thank you for doing the thinking bit on my next project, adding triggers to a novelty Calculator/DrumKit..🙏
I hoped you kept the most important feature and I was not disappointed
Very nicely explained
This is geniusssss!!! 😭
Nice! I did this same thing a while back with one of those toy drum kits with the roll-up rubber pads, but mine is kind of a poorly documented hack. You've done a fantastic tutorial here.

Oh, very nice i was just recently wondering how to trigger buttons with CV! Thank you for htis video!
You are a cool MF 🤘💖 . The sounds are perfect “low-fi 1990” drum sounds
Really cool. Was so hoping you were gonna hit that switch after programming the drums...❤🔥❤️
I like the resistor insertion special effect.
very cool 😀
Interesting Site you have. Will keep me busy for next couple of weeks. ❤️👍
Love it
amazing
Now I need to find a Sony TCM 4040!
Amazing module ! When do you start shipping them out ?
Brilliant work. I wish I understood electronics better than I do; I'd love to have a go at something like this. Looking at the reverse of the original PCB, I bet that second IC has a lot more sounds on it than the 8 you're using... though I'm not sure how you'd get access to them.

Nice! There might also be a resistor controlling the pitch on the circuit board. If you replace that for a pot you can also control the pitch of the drums/samples.

This board uses a crystal for the clock so there is no pitch resistor here. I do have some other toy PCBs that do have pitch resistors that I might feature in a future video though.
great video thanks, would be great to have a tutorial for begginers to know how to indetify the initals pins to run the extracted board, also i want to do the same with a casiotone mt-70 that i keept for a long time, and dont know how :/ thanks a lot again!
Why not add in some transistors to make the animal/drum switch voltage controllable? Then you could use a 3 position switch for manual override drums/cv or gate signal controlled/manual override animal sounds.

This definitely would've been possible. I just didn't decide to do it because I didn't feel the need for it personally. BTW here's another way to do it without a 3-way switch with an XOR gate: url.sandelinos.com/animalinstswitch

Great! How come you didnt replace the toggle with cv changeable so you could flip between animal and drum on the fly?
Can I ask - what soldering iron are you using (my next upgrade maybe. I'm using a TS100 atm
Would this 'transistor trigger' approach work with a PNP if the IC chip wanted the pin to go high?
@SandelinosDIY
Жыл бұрын
Yes but due to the nature of the PNP you'll have to add an inverting circuit in front of it. Here is the circuit I would use to trigger a toy that needs it's pins pulled up: url.sandelinos.com/invertedtoytrigger

I noticed you’re using trs patch cables, even though eurorack traditionally runs on ts jacks. Why?

I got a bunch of these TRS to serial cables(url.sandelinos.com/trsserial ) for free so I soldered patch cables out of them.

KiCad! It's awesome and it's free and open source.
I think if it were me, I'd have simply recreated the circuit on the strip board.
