- Part Two Of Making the drum machine!
I Have already started covering the sequencer in live-streams and vlogs this past couple of days on :- / lookmumnocomputer
You can watch back the livestream after! needless to say this supports the upcoming museum.

I was meant to add bit more info talking about the snare circuit in this video but somehow between bouncing and uploading I managed to lose 30 seconds of talking about the function of the circuit, I have no idea what happened I do apologise! I will be doing a recap video when this project is done on the look mum channel and I will make sure to include it. Rewatchable build stream of the sequencer from last night! :- www.patreon.com/posts/builders-flip-48382006
Stripboard Layout :- www.lookmumnocomputer.com/projects#/rhythm-generator
I will attempt to fill in what was said in the weirdly missing part on the description!
The trigger is received from the sequencer chip it goes into the first transistor which causes an opening decay, this is mixed with the noise circuit which then travels to the base of the second transistor which opens up and the resulting noise sound is filtered, its super simple. I filmed this whole video as a livestream last week! here it is :-

A PCB with all the drum sounds would be stellar
Analog drums are fascinating! It would be cool to have the mixing of the drum parts patchable should this become a module. That way you can mix the hi or the low bongo with the noise, or other wonkey combos!
Sounds very clean, cute and charming!
I love how you explain it using your hands as a visual aid
SaaaaWeEET!
This magazine and Electronics Today International, or ETi as it was also known, were on order at my local newsagents in the 70’s and 80’s. Almost my entire guitar effects collection were made by myself from designs in these magazines!
It's all about that low bongo and snare. Very USABLE!
The Thomas Band Box is the coolest tightest drum sounds when pushed into some distortion through my PA and I jam the organ to it. The Band Box was actually Grandmaster Flash's "secret weapon". You can see him playing it in an old video. The Thomas Playmate was the sequencer " programmed beats part of the system. Some organ just had the " any Key UPPER"/ any bass pedal LOWER triggers for the Band Box (drum sounds, plus manual buttons). Either way it was always the same Band Box whether with or without a playmate.
I really do like the CR-78/808 feel it has got, always loved tinny popcorn drums... Once the sound modules are finished a step sequencer will complete it. After that, expand it into a Eurorack unit, with the capacity to edit the sounds, and *sell that monster to the masses!*
I'll probably never build one, but I'm glad to see that this is out there on youtube and the schematics are available to everyone. Sounds great!
"I probably make a module out of it..." SOLD :D
Those drums sounded really great! The lower tone drums reminded me of my grandma's electronic organ, esp. in sequence, made by GEM probably in the 70s or early 80s (it had different rhythm presets like Polka, Waltz..), I've been thinking of recovering that organ and thanks for the video!
Gorgeous! Has an Yves Deruyter feel about it
Yeeeeeaaaaaaaah! Love when you dig into old electronic journals. Please check out the “sound bender” or whatever it was called. A simple thing built on a PCB that went with the mag (PE or EE) in late 70’s or early 80’s to be used as a VCA or RM.
I always used to show up for gigs with my circuits looking very similar to that! Rule #1: Always bring a bag of alligator clips if your gear is home made and barely put together!
lol
I understand round about 0.1% of the technical part in every video but the value of fascination and joy sparkling is 110%.
Maybe adding some distortion diodes and pots would be a nice extra touch for the low voices. Cool project...
this reminds me of a vox drum machine my brother had, this one was even simpler then vox's unit made in 1967 . so for sure look forward to building this to have that sound with alot more control over it.
..snare and clave sounds surprisingly good..
I love the White noise circuit with the envelope filtering. This is the basics of good old-fashioned analogue synthesizers
I still can't get over how few devices it takes to make drum sounds. This is freaking amazing
Sounds really good 👍
Now can we build a midi to cv and control the 70s from the 80s??
nice kit of drums sounds good
Whoaaa can't wait for part 3!
this is super inspiring and sounds great :)
0:42 that same font is used for the logo of rhythmbeat records an 80s house label. i wonder if they read this mag
Probably rub-on lettering, maybe Letraset. They liked using crazy rub-on fonts back then, before you could change everything in an instant.
looking forward to the module (:
Sounds great
Module would be nice!!!
Sounds rad
I hope we can get this on the website
they on ebay uk advertise the M253AA as 2 in the uk available. this is too cool and building both the project w/M253aa and this one too. never have too much drum/,. So the Harry and Meagan tell all will spill the beans about your new Museum opening..lol . WE can only hope !!!
could you combine this project with the big button sequencer? this would be amazing!!
0:33 you liked that case too, huh? I noticed that the other day, quite snazzy! I saw a pic of the original NASA control room today, and that's roughly what all their consoles looked like, only bigger and wider (desk size). But I have an even softer spot for when they have curves, like the ADM-3A.
Like the sound!
Nice man!
You won't gues what I've been "inventing" and building this past month😮😮
Nextlevel coincidence seeing you building a drumcomputer right now😮
I'm surprised by how decent these drums sounds are! Defs gonna have to make a module out of them myself! I really hope this sequencer is using relays or something else ridiculous! 😆
Reminds me of those korg electribe analog drums modules
I got feeling this going to become hole new drum machine. The 1978 to 2021 time traveller mod podge drum machine.
doctor who would be proud love your work Sam.🥰
nice
You could call it... T.A.R.D.R.U.M.S.!
How about... Tempo And Rhythm Drums Realtime Universal Multi-Sequencer! (when the sequencer bit is in)
It actually sounds pretty rad
I had the entire PE collection from 1973 through to the late 80's(?). It all started because they were publishing a synth (yes, THAT one). The Ingenuity Unlimited section was great for ideas, but quite a few didn't work - so: good for learning skills. I ended up dumping all the mags in a house move and probably will regret it forever.
I do remember that front cover, but never was interested enough to have a go at it.
Great channel(s). Oh btw, WHERE did you get the Lego Breadboard wotsit? Love that!
Killer. Good job!
blimmin good
cheers Sam :)
Cool!
Mind blown! 😉
We need sample pack of it!
4:50 WOAHHHHH
That's fucking dope.
the snare is surprisingly good
ha I know right!
Still dreaming of a Behringer CR-78 reissue : P
Have you ever built a DS-7 Drum Synce?
In your opinion, how difficult would it be to recreate Oberheim DMX or Linndrum drum machine while having all the schematics if one would be able to acquire the necessary parts? Thanks 😉
They are both sample based so not that difficult. The sounds are stored on ROM chips and it is entirely possible to make your own with EPROMs and a programmer.
Would've been great if you could (clearly) share the schematics, so other's could also build this.
Lovely jubbly 🙃😃
I kind of like the sound.
The 4.7k resistor in parallel with the 100mH inductor in the noise circuit section. In the magazine, in one figure the resistor isnt shown, in the circuit diagram it is. Is it needed or not.
I've been trying to recreate this circuit too but can't get the white noise to come through when triggered.
I've used 2n3904 transistors instead of bc108b (waiting for delivery) is transistor choice key to this circuit?
What is the trigger spike duration? 5volt 1 msec?
I'd.like to get a working version for myself too
Wohoo! :)
HOW IN THE WORLD?!?! did you change the time signature on the Beatstep Pro's drum channel without stopping the sequence first? 4:48 It looked like you just pressed shift and selected 1/4...mine wont let me change the time signature without stopping it first- I tried updating the firmware and still won't let me unless I stop the sequence.
it should, contact Arturia
@@THISMUSEUMISNOTOBSOLETE thank you for replying! I just sent them a message through their contact page. And thank you for sharing awesome content, I never know what I might learn!!!
Sounds like the silver apples :-)
😍😁🥁
0:21 I would pay for a high-res scan of that "INGENUITY UNLIMITED" on a tshirt
found it online nvm
The snare sounds very 909!
Sweeeeet!!!
Make it in to a eurorack module...
kosmo format > eurorack
sounds just like a volca beats
i know analog ele tronics. i can build them. but... its a pain in the ass . sometimes. so i resort to using an.....arduino.where can i read the schematics for this one?
Your test music was starting to sound a little like Plastikman. Good job!
is using a cd4011BE a problem in this circuit ?
infact it is preferable
@@THISMUSEUMISNOTOBSOLETE is there a BOM somewhere or i just need look over the strip board layout ?
The CD4011BE does not work !!!! have tried many myself! It has to be a CD4011AE!
@@maikmario71 confirmed? I’ve build this circuit with cd4011be and makes rather unpleasant sounds.
@@maikmario71 Nevermind. Seems to be true. I’ve looked on the forum.
Get him connected to the BIG BUTTON!
its been suggested but im not doesnyt seem right plonking in an Arduino ha
DFAM. Drummer from Another Magazine. 😂
low bongo
clock: a
minimal fans: UOOOOOOOOOOOOOOOOOOOO
I'd like to be able to read schematics and then create that stuff. :'(
you can learn it , it looks complicated in the beginning but its actually not that hard :) there are lots of great tutorials on here . best way to get started is to search for a simple circuit , get the parts and just throw yourself into it . maybe try an lm386 amplifier , low parts count with some of the basic components to get started with . good luck and more important have fun ! :D
A good to know circuit for starting is the triple 5 timer. 555 is so versatile and useful. It is a timer, square wave oscillator
@@cosmiceon or even easier , cd40106 , only needs a cap and a resistor , and with a diode you can even get a sawtooth and a square wave goin ! :D
For whatever reason strip board is crazy expensive in the U.S. while the pad-per-hole stuff is dirt cheap. Whatever.
at the moment making a custom pcb is cheaper than buying proto/stripboard, or do like a friend does have JLPCB spit out (custom) protoboards
@@gideonwackers7693 what is the turn around time? From order to delivery?
I never knew about stripboard until a few years ago, and I've been dabbling with electronics since the mid-70s. It's apparently been common in UK projects since forever, but almost unknown the US. I used more than a few of the breadboard layout boards though, and plenty of donuts-only boards.
But now if you can wait two weeks, you get some nice boards from JLPCB. I made some boards with LEDs and SMT transistors and a pin header that plugs into a breadboard, because I got tired of making that circuit by hand.
@@j0nny93rs quite fast, it mainly depends on which shipping option you take and where you live
Everything works, except for the snare which doesn't work properly, too bad!
updated it it should work now, note the red wire for power in is on the other side of the 7805 and also if you still have trouble put a 100k resistor between the snare trigger input and ground, some power supplies need it
@@THISMUSEUMISNOTOBSOLETE Many thanks Sam !!!
I've heard far worse snares on modern kit
hmmmm..... ?
huh?
oh...
@@VeraTR909 ahhh
Wha?!
Are you snorting cocaine? Slow down man. 1:29 that is a capacitor, not a resistor.
its the speed i go unfortunately. no drugs for me.
