[@THISMUSEUMISNOTOBSOLETE]

by the way have you heard about this! www.gofundme.com/f/what-would-you-do-with-just-250-days "We are a team of film industry technicians and are creating this fundraiser for our long-time friend and colleague, electrical engineer Lucien Nunes, to help him fulfil high life-long goal of creating a unique Museum for Electricity and Electronic Technology - MEET."

[@NicStage]

The more well-known relics (Linndrums, etc) are important and interesting for their influence. But these old kit things are a better example of how interested we were as a society in synthesis and music tech. I can't look at something like that and not imagine the person who saved some money, got it, and spent time putting it all together. If they could see the future, they would probably be so pleased that their work was being used to inspire people today.

[@LOOKMUMNOCOMPUTER]

Yeah that’s the thing imagining someone saving up and spending ages figuring it out!!

[@KaijuInvadesNYC]

Maybe I'm reading too much into it, but you seem kind of overwhelmed in this video...so it's probably a good idea to remind yourself these are your dreams overwhelming you, which is a very rare (and insanely positive) thing!

[@LOOKMUMNOCOMPUTER]

Hey all good. Overwhelmed is my average state ha. I, like most people set my workload on the optimistic side of things :D. But it’s just about knuckling through it. I wasn’t intending for that to come across in any shape negatively. The process is a very rewarding experience I was just hoping to portray that getting stuff sorted out like this takes time that’s all :). And yes I’m always very greatful for the opportunity to be doing what I do. It’s just always a tad daunting attempting to grow something beyond myself, and get Something proper off the ground like this museum, but let’s see how it goes!

[@LOOKMUMNOCOMPUTER]

Maybe I read into your comment wrong I might add. But yes awfully positive and thanks for watching the vids!

[@KaijuInvadesNYC]

@@LOOKMUMNOCOMPUTER Cool, man. Definitely was NOT criticizing! You effing rule...world would be a better place if we all spent a fraction of the time you do actually DOING something...

[@Veptis]

While I don't have any interest for the phone stuff (that's just history of utilities), I love the idea of those old multi part DIY projects, I didn't have that in my childhood, and the main purpose is art. I am excited to see the videos you already did on it during the next few weeks.

[@rbrooks2007]

The now late Dr. Peter Zinovieff was giving away the circuit diagrams of his range of EMS synthesizers away for free to anyone who asked in the 70s. The pages are still floating around the Internet.

[@coalcrackerchris]

Love the precariously placed box that says fragile!

[@RayMcNamaraMusic]

I love you telling us what a mess the back of this is as if we didn’t all see your recent hot glue nightmare of a fish module.

[@LOOKMUMNOCOMPUTER]

That wasn’t a mess though, that was just fast prototyping 👍👍👍 edit just to add... A couple of people commented on that video saying I hope my students don't see this. Which I think is a bit of a shame. Hot glue does have a place in building things. And people shouldn't shy away from it for making proof of concepts of fast prototypes of low voltage items. It wasn't messy and if anything it's actually a bit more robust than some of my other builds. Intact if anything that approach to building and designing is quite freeing. However this is a pretty involved synth and there are a lot of wires and it's a tad confusing the bass module was not.

[@RayMcNamaraMusic]

I fully agree. Only poking fun.

[@LOOKMUMNOCOMPUTER]

Ha all good. 👍👍

[@jeanbonnefoy1377]

Blyme! I started building Formant modules in the mid 70s, bought at an electronic shop on Nation Square in Paris, next to where I used to live then. They were initially describe in Elektor, a Dutch diy electronic magazine. I still have the Formant book in English and I kept also several issues of Elektor magazine stored somewhere...

[@stephenrock4541]

A lot of arcade video machines during the 70s and 80s used those connectors

[@thespazdragon]

Word of advice: Smooth, non-porous surfaces in the toilet. Fuzzy and rough things become a nightmare to keep clean.

[@BeTheAeroplane]

A couple of those screw terminals chained together was how I grounded everything in the first iteration of my synth, then +5 was soldered into the back of each module along a chain so all of the panels were actually soldered together 😅

[@LOOKMUMNOCOMPUTER]

Haha we all do things like this at some point! It’s commendable this thing apparently works but it’s just going to turn into a headache when plugging and unplugging stuff so I figured first thing is sort it out a bit

[@BeTheAeroplane]

[@truthbydesign5146]

I hope you dedicate a decent amount of time working out a good security system for your museum. Even if the gear isn’t super pricey, a thief won’t likely know that. You’ve put an extraordinary amount of time, love and passion into this and that’s worth a lot - and definitely worth protecting.

@@THISMUSEUMISNOTOBSOLETE when I was about fourteen I lived in England for about 2 weeks at one point and then I a week the year later. It would be a nice change of pace from the US though

[@Whiteseastudio]

I have a lot of those sockets laying around… how many do you need?

[@THISMUSEUMISNOTOBSOLETE]

keep hold of em im sure you'll need em for a project :D I think I have found them on rs components luckily people had them, how come you have them? are they a regular studio connector??

[@sparkyprojects]

If you're using 7815 & 7915, then just use a 7805 for the 5v which can be tapped from the 15v after the 7815 yep, i remember seeing the formant in elektor at the time.

[@THISMUSEUMISNOTOBSOLETE]

hey up sparky. yeahhh I was going to do something where I split it off and add multiple regulators, as I have no idea of the current pull on the 5v so I was gunna just overbuild it and give it its own 7815, but lets see!!!

[@sparkyprojects]

@@THISMUSEUMISNOTOBSOLETE I hope you realise you can parallel those regulators, i currenlty have a psu with doubled regs (5v & 12v), but yeah, you could take the 5v reg from the supply side, just remember there will be more volt drop, so more heat

[@THISMUSEUMISNOTOBSOLETE]

@@sparkyprojects yeah but thats the reason I would go through them in series seperatly, as excess current or excess voltage results in heat, so the 7805 going after a 7815 would be less heat

[@AnalogDude_]

It's obligated to do that, if you use 7812 and 7912 voltage regulators, you really should use a 15 Volt center tapped transformer, if you use a 18 volt center tapped transformer the regulators will become very hot ( unless you add really really GIANT heat sink to that, but a really massive one). so if you have a 15 volt transformer and step down to 5 Volt, eggs can be baken on there. that's a massive overhead of 10 volt. that's called wasting a lot of volts into unusable heat, i believe there is a formula for that in the datasheet or somewhere for that.

[@djneon12]

you have the elektuur formant documentation but there is also a german expansion book with more modules if i remember correct. and the connector is a DIN 41617 31 pin. ASSMANN WSW stil make those product number: "A 31-L2/SILVER" female connector , "A 31-S1/SILVER" male connector rs components still have them in stock.

[@256byteram]

The sockets on the synth are in the DIN 41617 family. RS, Farnell, etc sell them. Cheers.

Moini Sam hab mir die Tage auch ein echt riesen Mischpult aus den 70igern gekauft und bin echt gespannt was das für ein Projekt wird.. Im Internet findet man zwar ein paar Informationen über den Hersteller und hier und da auch die eine oder andere Info über eins zwei Modelle aus dieser Zeit aber über das Pult welches ich aus einer alten Firma gerettet habe gibt es weder eine Info noch ein Foto und auch kein zweites Angebot im Netz... Was ich doch schon recht spannend finde.. Denn für mich macht es den Eindruck als sei ich da auf was seltenes und besonders gestoßen 😎🤟und ich freue mich schon drauf das gute Teil wieder fit zu bekommen und es für meine Musik zu nutzen 👌ich bin gespannt was das für ein Abenteuer wird 😁🤟

Can you partner with schools or any autism/aspergers groups, STEM groups, etc. and maybe do some field trips for students to come learn about old tech? Maybe even get an intern to help you out.

[@angst_]

Woundnt a switching voltage regulator be better/more efficient/cooler than a linear regulator? Maybe they make more noise that's counter productive to a clean analog sound signal?

[@LOOKMUMNOCOMPUTER]

It’s a noise and space thing. That space that janky switched thing is taken up is where the Kov is supposed to go. It’s mains. I dunno just don’t feel right being in there

[@lazybonesftw9433]

Never been so excited to use someones toilet

[@AnalogDude_]

hmmm, the SMPS (supply) isn't bad, Moog and others have used them, even Doepfer sells a power supply that uses them, brand = MEANWELL, using 3 of them, +12V, -12V and +5 Volt. Just when you're finished repairing the thing, check with a scope to see if the Voltage is stable, meaning no noise if there is just add (various of types and values) capacitors until you have filtered out the noise. you might need to add an extra bus PCB for the power rails that holds the capacitors. maybe it even has a trimmer to adjust the voltage.

[@AnalogDude_]

.... besides the efficiency of the SMPS is much much better than a linear (78xx/79xx), accept the switching noise.

[@LOOKMUMNOCOMPUTER]

@@AnalogDude_ yeah it is but it’s massive and in the way of where the KOV is supposed to go. Besides I think I’m gunna do the power supply in the formant book now. 👍 as someone emailed saying they had one of the original pcbs for the power so may aswell do it properly I guess ha. If that doesn’t come off I thought about it after doing this and may just use the power supply that’s already there just with a cleaned up pcb bus board. Will see if the original power pcb comes off first.

[@AnalogDude_]

@@LOOKMUMNOCOMPUTER the size doesn't look like a huge head ache to me and when closed again, it's out of view. : ) the SMPS is much much more efficient. that's the cool factor of these power supplies, by switching a TINY transformer like 80.000 or more a second and have more amps than a bigger transformer. accept they have noise built in by design and the metal housing is obligated to keep the noise inside. also less weight. MEANWELL, a thing to look out for, retail shops where i did some installations have them laying on top of their system ceilings to power (Christmas decoration) leds and what not.

[@AnalogDude_]
