Electronically they are not that complex (ie theory of operation), troublesome part is wiring - you don't have Chinese sweatshop workers/nearby technical school internes building your prototypes at enthusiast's lab, so it takes ages of mindless work to for example wire all the switches from the keys. Copy and paste of 50 switch debounce doesn't make project complex, it just makes it awful to build (hence Ben didn't use bucket of 555s because of time constraints):)

It's practically impossible to build a 555 based keyboard that size without trim pots and just resistors. As you mentioned, the resistors very sensitive to heat, hence need easy access tenability of every key vs 1% variance resistors etc.

Yes, a simple oscillator design like this is going to be temperature-sensitive. You could get away with it with vacuum tubes because they generate their own heat and thus are less sensitive to the ambient temperature, but with solid-state circuitry, just putting your finger on the transistor or IC will warm it up enough to cause it to change frequency!

There are ways to compensate for this. One way is to use resistors with a very specific change in resistance by temperature. They call them tempco resistors. Design your circuit around these tempcos and you can get a stable analog signal within a given temperature range. Another way is to actually "take charge" of the heating using a heat source and a feedback loop (typically a DAC connected to a CPU). When the DAC tells you you're too cold, you increase the current through the heat source, and when the DAC tells you you're too hot, reduce the current. That way the chip stays at a consistent temperature, regardless of ambient temperature.

The old analogue synths often had something like a thermistor bonded to the main oscillator chip(or transistor array) to compensate for temperature drift. This is a project that they could have done better with a Raspberry PI/or micro controller or if they had done more research they could have just implemented a single oscillator analogue control voltage and gate system. Glad they tried anyway.

I guess building 12 oscillators and then dividing down with a flip flop would make more sense. You'd still need some sort of VCA per key then... Part count gets out of hand fast, indeed. Although, old transistor organs did something similar.

I have thought about it for some time but I got to ask. It would be great to see how you go about composing. I mean, what are your routine go to stuff (key, chord progression, melody relationship to chords)? you have distinct style/ sound to your melodies.

as I recall from bens vid, it uses the 555 timer chip 4 sound, so other waveforms ar not nearly as easy to do as you would think. and if you say he used 556 not 555, their the same thing, but 556 hat 2 555's in it.

Was I not completly broke I would support this channel on Patreon. Suscribed and notifications bell on. Keep up the good work.

Awesome vid David! Super interesting.

it would be a great cross over episode if you took the keyboard back to Ben and he could get it working again =^.,.^=!

That keyboard is only good for making the soundtrack of a Taco Bell bathroom...

They say that when two of your favorite youtubers collaborate on something. A star is born.. :) Fun to see for the rest of us at the very least.. :)

love these vids keep em coming please

Too bad you can't tumbs-down a thumbs-down and turn it into a thumbs-up.

5:50 Whenever I try to play any instrument

I love when my favorite youtubers come together and collaborate!

Holy crap! I love the Ben Heck Show. I have one of Ben's shirts I won in a can crusher design contest. The ditty was awesome, BTW.

3:36 Sounds like a printer

A bit hard on Ben and the build there I thought

Not really, he's just saying as a practical keyboard it's junk as you nead more polyphony and it needs to stay in tune and all that. But he's also saying that as a proof of concept its a really good idea that he enjoyed playing around with. Ben says its not as good as it could be due to his self imposed time limit and design choices to make it a quicker build. He does a llt of projects and cant afford yto get bogged down.

Eh, not really. It was a quick build, it is just a concept. I'm sure Ben and Felix just wanted to see if they actually could build a keyboard before they started building something more advanced and bigger.

It was a bit blunt perhaps, but to be honest, it was kind of a ridiculous design on Ben's part. Especially if they were on a time crunch, it seems like they actually made it way more complicated than it really needed to be, and made it worse as a result.

Daniel G That I can agree on. There were some things that they could've done better just as fast, but I still think it's an interesting concept with no microchips or anything!

Mmm, jury's out still. I like 8bit guy tons but Ben really knows his stuff so sounded a bit "meh" when in fact with time constraints it was very well executed - and 8bit guy probably couldnt do it himself in that timeframe.

That reminds me of a keyboard I built in the 70's, but it didn't have piano keys, just telegraph-style switches.

dude that actually super-jammed. So hard in fact that you annihilated the keyboard. 10/10

The Ben Heck Show stuff is allways interesting and they have a lot of knowledge- BUT I allways think they put not enough thought in their concepts to make a good result- and than they ALLWAYS rush things an make stuff kind of useless in the end....

Ben Heck is a fantastic electrical engineer. All the folks in these comments couldn't do a tenth of what he can do with a soldering iron

yeah. Why is everyone being so harsh to Ben & Felix. It's such an awesome project, and it works quite well. It could've even been shipping that caused it to fail. It doesn't even have a sound chip and it still sounded good. I doubt 90%+ of everyone watching this video can actually comprehend how to build a keyboard of their own like Ben & Felix did. So much disrespect in the comments. It's like telling an artist their art is shit when it's their first time trying out watercolour; instead of the usual pencil drawings. Ben isn't technically a professional in the field of music, but he is at pretty much everything else to do with electronics. People are being way too harsh

That may all be true but this is intended to be a musical instrument, it serves a single purpose and it should be judged by its performance. If someone enginered a midi guitar but didnt bother with proper fretboard then it would be useless defeating the purpose of engineering it. As a viewer I see this video as showcasing a prototype which is nonfunctional.

Great! Been expecting this collaboration for so long that I forgot about it lol

that was an interesting build to watch, Ben does some pretty cool stuff, I like his laser harp he did a while ago.

What's so Atari about it?

COUGH COUGH!!! Original designers my ass....Forrest Mims designed this circuits and published it in a series of cool little electronics schematics book, published in 1980 to look like someones hand drawn notes. At some point some people hit on this circuit and started selling kits of it to make money out of someone else's design, give it a stupid name, and inspire a million numbskulls to make horrendous sounds with this god awful design. I include myself in that. The best thing I ever did was throw away all my 555 chips, although someone did actually manage to make the 555 chip sing, the Thomas Henry 555 VCO is an osciallator worth playing, it;s a much more complicated build than this however (and way more expensive) but if they could build a keyboard that had 4 of those, which could be either across the 4 octaves or put into some unison mode, they would build a serious contender for a worthy synth. Akai released something like that which famously sounded awful at NAMM as it never kept tune at all, all the demo videos are beyond funny, I don't know if they ever released that synth, but surely these guys could build something better than it.

555 timers aren't exactly really related to Atari.

Cool project. I did something similar to that about 20 years ago. It only used 1 555 timer for a clock source and 4 chips called "top octive dividers". They were intended for the highest octive and to get the next lower octive divide each note by 2, but I divided the clock source by 2 for each octive. I fed each note through a keyboard from an organ to 44 100k resistors as a mixer. I only needed to adjust one pot to tune the whole kb and got full 44 note polyphonic output..

Awesome work David! Love your videos! Any chance you might do a review or demos of any of the Roland AX series "keytars" some day? I've seen a pair played live by Freezepop and they were incredible, I'd love to hear your take on them.

One of the most horrible things I've heard lol. Junk tunes on ZX Spectrum 48k sounded better

This was a great video but crap keyboard worthy of the dumpster. Time restraints or not Ben Heck but if you're going to build something, DO IT RIGHT!!!!!!.

ThePacratz it was just a fun little project, not a design for commercial use. Most people don’t even know where to begin with a project like this.

this is amazing! you should have more subs!

That was COOL! I remember hearing people in electroncs class toying with the very idea of this. It's neat to see it in operation.

Ben Heck - over complicated and over engineered solutions to problems that do not exist. He's done some great things, but builds like this just seem pointless.

To be honest, it sounds terrible... ^^' No offense though, I'm sure it wasn't easy to build!

Well I see you got the collab you wanted! Congrats!

555 chips rely on capacitor discharge time to generate a pulse and if flat ceramic caps are used then the timing will be greatly affected by the ambient temperature.

Where does Atari come in place? Did I miss something? Btw, that is actually an immature and next to useless device. Rather a waste of time, honestly. In respect for the effort involved I hesitate becoming explicit. If you do something, do it right.

I cant remember the details but the keyboard is essentially using the same method to create sound that the old Atari used. This was more a prototype to see if it could be done, a lot of effort but they learnt things and created something interesting.

"I honestly and totally respect the effort and the skills" Then act like it, instead of being a pretentious jerk. This isn't something that's supposed to have a utilitarian purpose. It's for fun and also serves as a teaching tool for basic electronics.

This episode was awesome!

"When you turn on the camera, things break", thats true! Last time I was going to make a video, I broke my camera.

I've been building keyboard instruments now for 62 years and this is the weirdest of all. What a fascinating item. Thanks for sharing.

You did it again : ) Great surprise, thanks a lot!

this reminds me a lot of a synth i built in university. the more pots you use, the worse it gets hahaha. i built a very simple 2 oscillator polyphonic synth, wanted to do 2 octaves but even cheap parts are expensive. the polyphony ended up working alright (but adding waves meant you would have to lower amplitude somehow), and i even ended up having it generate some cool polyrhythms as a result of the waves adding the way they did. the synth was glued onto a plank of wood and i think most of the cables are now missing. but watching this was a cool trip down memory lane

Great to see that beast again!

That was awesome. I think it's a beast already, making a circuit for each one would have made it ridiculously heavy

When just using circuitry without any sort of computronics, you can expect this sort of inaccuracy. That said, this was really neat, and pretty damn sweet.

The way the notes within a single group combine makes perfect sense if you consider the way that resistors in parallel behave. :)

I have no Idea why Im so obsessed with this channel.

Great video!
