The module you have is part of the control console for a AMS Neve digital console. No audio traveled through these boards, they where just the front end control. All the processing was in a large rack in the back end.
The knobs were touch sensitive. It was a really amazing piece of Kit.
I used to work for the company.
Any insights on where one might acquire one of these modules (in Germany)? :D
That whole panel is amazing. Did you guys design the encoders yourselves?
@@glnnk_art I have no idea. Search for AMS Logic 1?
I believe that the design of the encoders are patented. Yes they were designed by some very smart engineers. I was just a field service tech for the company.@@PaulSpades
@@glennspecht They did well, and I'm sure you were also good at your job. Thanks for feeding my curiosity. Cheers!
panel go beep
panel go boop
Beep boop, in fact
lol 😂
"I just needed to make a PCB" .... to me that's like "I just needed to flap my arms to fly" .... That board is really nice
40$ for that panel is a steal! Those 16 LED Dot matrix displays alone are worth a fortune. They can still be bought from new but are really expensive.
Really great find and nice project you made with it :)
Yep I bought 2 of those displays back in 2008 and it cost me something like $50. Bitluni you scored!
Also good old Sprite(tm) good to see he's still kicking it
Looks like a module from a AMS Neve Logic 2 series sound desk. The 'in thing' to have in the late 1990s in Film and TV. Found in Hollywood, Pinewood and the BBC in the UK if you were into sound dubbing. Often accompanied by an AMS Audiofile, one of the World's first dedicated digital hard disc audio track layers/editor machines. Spent several years of my life teaching people how to use this box of tricks.
It's from the AMS Neve MMC series of consoles from the early 2000's.
Disney and Fox still have significant Logic DFC installations in Los Angeles (I’ve worked on the Disney one a little). I remember when Sony was disposing of its Harrison MPCs and entire pallets of these modules all going out to scrap.
@@Gin-toki the MMC console had the knobs staggered left/right for ease of access. The Logic 2 and derivatives such as the DFC console which pre-dated the MMC had the knobs in a line on the right hand side as per the module used.
The visual appeal of this is irresistible!
I would love to see what you and Sam of Look mum, no computer! would come up with
This project is amazing!
My idea would be to transform this thing to a Midi controller.
It got a bunch of knobs and buttons!
What a gorgeous board. That's awesome.
I keep hearing a fragment of the Wilhelm scream as one of the sounds coming from the synth?! Maybe I should go outside more... 😜
i heard it too!
It's definitely the Wilhelm scream
Love this piece of gear you turned into your own DIY customized sequencer.
I heard about Apex electronics years ago but never had made the trip until you reminded me and I finally went yesterday. Such an amazing fun place to wander through. Thank you for your video.
How can yo be THAT versatile in your skills?
what an awesome project!
Very cool project! Nothing beats hardware and fiddling with real knobs.
Unbelievable! The skill set demonstrated here is next level.
Once upon a time this was a part of an AMS Logic 1 Digital Mixer
Wow, the knowledge you possess is fantastic especially the board design. Oh, WOW, what a fantastic synth
That panel has so much soul to it. Love it.
It's another WOW! Amazing work by both you and SpriteTM. Thanks for sharing!
The knobs by themselves are amazing with that many leds, wow
I so want some of those knobs with the LEDs. No idea what I'd do with them, but so cool!
is there any scrapyard like that in germany? to me that shot in the video looked like paradise!
THIS IS SO GOD DAMN RAD
holy moly, I love this sooo much!
I didn't understand ANY of this, so glad there are people like you in this world.
where is this scrapyard???
crazy skills! i just built a strampler module with an ESP32 and it nearly melted my brain
this is more of a "DIM Music Sequencer" since OTHERS can't really make it based on your video. awesome.....
Looks like a bunch of safes and keypads for some elaborate escape game. Tolles Projekt!
Did I just hear the Wilhelm scream? 😆
I am super-jealous! This project is awesome, and you are awesome! Will be happy to see some music live-streams)
Comes from a Neve DFC console for movies, still in use today in some post production studios in Paris
This is an awesome project. Fantastic score for this control board, makes the entire project very professional. You should build a coctail machine, each knob controls one ingredient. Would make for a hell of a live stream test :)
Pretty sure my team was in the surplus store with yah after the Supercon because we snagged one of those same units!! Such an awesome hack -- sent your project to my peeps
Fantastic. The controller is from a AMS Neve DFC console (a Film mixing console). I worked for them maybe 5 years before this version built in 1998…. Great to see it in use…. AMS Neve still active from Burnley in UK…
Awesome!
Just a question, how come the SDMs output connected to the speaker produces the correct sound?
If the duty cycle is set based on the value of a sin wave, the SDM output should not also be the same sine wave. Or does it create a different wave with similar frequency components, due to the next_sample() function oscillating between {-127, 128} at 440Hz? However wouldn't this mean that while the output of a certain sample is close to 0, the duty cycle will be half, and there will be some high-frequency noise on the signal? I did not see this happening on the oscilloscope output at 5:50 , but it could have been clipped due to its high frequency. I'm not sure how this would not change the sound coming from the speaker.
Basically, is there a reason why controlling the SDMs with certain signals basically produces the same signal at the output, or is the output from the SDMs demodulated before it is fed to the speaker? If it is not demodulated, how can that speaker operate when it is receiving a digital signal, without losing audio quality, etc..?
Edit: According to Wikipedia, a PDM signal, which the SDMs produce can be decoded to analog using a low pass filter, as this will just yield the average signal strength over time. Was this included in the design, or excluded for some reason?
I have zero practical use for such a thing, but just the look of it turns on the nerd in me! So many knobs, buttons and little displays. I love how you made it into a mod tracker player. If you do anything else with this, please make a video about it!
Great I love the fact that you’re using old stuff to make new ones
Great project. Watched your presentation from the wintergatan meetup, didnt know you were into music instruments from the beginning.!,👍
Is that available as a video online?
I have no clue about audio stuff, but you have single-handedly ensured I will spend the next week scavenging ebay for those tiny matrix displays :)
you're a diy audio god. Incredible.
Crazy panel, basically a better looking korg emx
I thought that was you at supercon, but I didn’t get a chance to say hi.
Awesome project as always! And damn I really need to make the trip out to apex, that place looks so cool
Amazing project. Especially the reverse engineering
@:30 in the upper right is an Abekas 8100 video switcher. Spent a lot of time hunched over that thing a lifetime ago.
Great !!! I am making something similar, thanks to share your jobs!!!!
wow great project
what ground is being used for the amplifier? If the ground used for the amp is the same as the power, that is why there is noise from the amp.
I wish I could reverse engineer something this size. Amazing work!
That is some beautiful hardware
I love the way the lights are shining true the knobs.
Can you share some detailed pictures?
I realy like this project.
Cool video
I'm curious. Is there a reason why you cut out the whole board for the antenna instead of just cutting out the ground plane?
Fun to see Sprite_TM here!
His embedded skills are on another level.
Great project and video. The 4x4 rotary encoder matrix reminds me of the Akai MPCX with the leds around the encoder and the small display per encoder. would be cool if you could get your device to work similar as on the MPCX, but with the much cheaper MPC One (or even the MPC PC software). MPC's run on Linux. Probably way too ambitious, but I also know you like challenges.
That thing is beautiful! What an amazing project. I vote for a wooden case.
3:35 - Really nice looking boards. I like the matte green solder mask. Just curious, is that standard or an option?
This is the standard soldermask we use at AISLER.
Awesome! But where is that store where you find these old parts?
Fyi, you can use sigma-delta modulation with DMA. You simply need to use I2S but use the PDM output method. Downside is that you only get one channel, but I think you could use two I2S peripherals to get stereo. Upside aside from DMA is that it's a higher-precision delta-sigma (the one you use is only 8-bit) system as well.
This is next level.
Mr awesome, thanks for the video
"I just had to make a PBC" 😂
Thanks for this masterpiece, really love your content and cant await the next one! when will your risc v project be continued?
greetings from niedersachsen :)
Great project, wouldn't these panels be the perfect base for a midi 2.0 project?
I really would like to have one of this panels for our light control console, these 90s-2000 tec is quite ok to reverse engineer and put to other use.
Is this an Eurorack module? Very nice panel but I have no idea what kind of projects this can be used for. Maybe you can turn it into a fancy pancy (wireless) home appliance/light (remote) controller. Or you can save it to make an "April fools day" prank device (in a box that looks like a RC-remote with belt and huge antenna) that can open bridges, change traffic lights, edit electronic road billboards (or any other billboard), change all of the TV's at an electronics store to an impressive light show, control the behaviour of humans, and so on. 😆 After this, you can make a "making of" video to show us how you achieved this.
Awww mit davedarko und tinyledmatrix b-roll vom letzten Jahr :3
Those panels are amazing!
I want one (or multiple even) and I don't even know for what hahahaha
Also, very impressed by how quickly Sprite RE'd everything, maybe one day I will be able to do it too)
Interesting how the panel uses an FPGA instead of a microcontroller, I wonder why... I guess the reason might just be "90's" 😅
im jealous as heck for that cool ass thing
i would even say, there is so much cool stuff at this scrapyard place. i wish i could go there once. but i doubt its gonna happen. its around the globe for me
Really cool video, E-waste so many uses.
Super cool!!!
Very useful.
@8:12 Why do you flash (one frame!!) the text "the octave isn't correct... I know" ?
Holy shit, this is so awesome
amazing!
Brilliant
I think you're onto something with that Phased Array Sonar. I look forward to part 3. Here's what I'd love to see: can you use it to spot bugs that are flying? Can you identify different kinds of bugs based on various traits? While I do understand the principles of what you are doing...I feel like you are HUGELY more efficient at pushing this idea forward than I would be.
As for why I want this? If you could cover a 60 degree arc (in 3 dimensions, so a cone) then you could slave that to a pulsed infrared laser at around 3 watts of output. Find a mosquito? 50ms pulse to kill it. See a fruit fly? 100ms pulse. See a honeybee? Bees are friend, do not engage! See invasive beetle? *zap*
Ultrasonic may be the wrong tool for this job, but every right tool starts somewhere wrong. :)
woah... This is kool mhaan 👍👍👍
beep boop
beep boop
geiler kanal 🤓 love your gefrickel
What are those audio panels called? I innocently put "beep boop panel" in Google and nothing like that appears, hehe.
I want to have scrapyard like you near me, holy shit, that panel alone is probably worth $1000
if that was just a modular synth interfaced step sequencer that would be awsome. with CV and gate signals out or midi out so it could play other synth modules
Where is that Scrapyard? I need to go there
It's a tracker????? This is INSANE.
Are those debugging and development livestreams available?
bitluni live channel. playlist is linked in the card in the video at the start of the assembly
This is how pure joy and happiness look like
Bitluni is the most intelligent Electronic youtuber i have ever seen
Great !!! Are you using ESP32´s DAC ?
esp32s3 has no dacs unfortunately
😯😯😯😯@@bitlunislab
Very impressive reverse engineering and repurposing of some very unique hardware. I think you may be at the Apex of your game! 😆
Quality.
Should be nammed HexaDecMod a 4x4 mod of OctaMed 😂 🎉 Great work 👍
Imagine using that as a macropad for your computer!
Wilhelm scream sample???
Subscribed.
That thing would be amazing in a home flight simulator.. it almost looks like airplane radio controlls
You are so lucky. I wish I had your skills, education, and training! I have the intellectual ability but like you said, made some poor life choices! I went philosophy, law, then backtracked to science and found late in life an innate ability that my parents purposefully quashed. I am a 4th generation lawyer who found an aptitude test from 12 which said science!
My god. Look at those smoooooth encoders :o and their pretty led rings. I'm in love. Who the hell makes those?
They're unfortunately custom made for the company which made the mixing console this module is from. (I can't remember what brand it is)
This console is called Ams Neve DFC3D. It has a ton of panels like in this video
All these nice Encoders and Displays are actually nerd p*rn :D
3G SDI to HDMI converters exist. 1 GPIO pin for video and audio.
Add sampling functionality!
Make this into midi controller, it can be super cool. Even a wireless midi controller maybe ?
Price?
Wow 16 steps and lcds? I want this for my 303 sequencer
Well the Korg Minilogue; Monologue; and Prologue were inspired by the Korg Monotron…
I think you should consult with HainBach, Look Mum No Computer and Kinkas -Synth DIY.
FaderFox maybe a GIT Hub Source…
