Julian: 10 audio jacks on a PCB Apple: （・o・；）

[@Ogma3bandcamp]

I won't lie, I haven't clicked on a Julian video for over 6 months. I subscribed years ago after the very first vocoder vid. Clicked on this one s soon as I saw it. Great to see the project has had a new lease of life, excellent stuff.

[@jlucasound]

HEY!! I need a Vocoder!! I think. C'mon! It's so cool and old school!! :-) Thank You Julian for being here.

[@makingsense2268]

To help with reaming parts like the fibre washers, try turning them in the opposite direction! That will make the reamer much less "bitey" and gradually wear the washer inside diameter in a more controllable fashion. (In a similar mode, when using a cutting tool like a hole saw in plastic, run it backwards and melt your way through, it gives a better result than ripping through soft material in the "proper" cutting direction.)

[@JulianIlett]

I did that on the polycarbonate roofing panels on my workzone. Piloted with 3mm forward direction - opened out to 8mm in reverse direction :)

[@MasterIvo]

I would LOVE to have your analog vocoder.

[@mrroobarb]

Julian are you aware of a new device to aid attaching PCB components that is worn slightly below head height? I like to call it the "over shoulder solder holder"... or as the Americans call it, the "over shodder sodder hodder" :-)

[@jlucasound]

Wow! A Flash Desbo (may be wrong; long time and my Nat. Lampoon LP is in storage) reference! "OK..You untie me and I walk away and come back later..? OK? Hey, Hey! There's a telephone call for you!" Don't forget the "Band of Suicide Suppositories". ;-)

[@pintokitkat]

Lower SWG solder would be bolder solder. And solder not on a roll would be folder solder. AU and tin would be your golder solder and stuff in a handy dispenser would be holder solder.

[@doktoruzo]

looking forward to seeing this finished Julian. very interesting.

[@tubical71]

I think you know, that if you simply put inputs in parallel without any sort of decoupling they gonna interfere with each other, like damping, alter the bandwith, adding noise along with some other "funny" side-effects....

[@AlternativeDIYEnergy]

Colder/Older solder. Well. May the 4th be with you my friend.

Julian, as someone with mild OCD you should realise that you CANNOT finish the video until the assembly is COMPLETE.

Anxiously awaiting the PCB video for the inputs you plan to wire into a giant touchpad under the back yard frogs as a white noise source.

[@Richardincancale]

If you left the solder in the garden for a few months it could have been your Older Colder Solder!

[@ElmerFuddGun]

It's great that you are finally getting this Vocoder built, Julian!

[@barryg41]

Eight adverts! Sheeeeesh!

[@Zadster]

If you slid those reels of solder onto a piece of wooden dowel to keep them tidy, would that be a colder older solder holder?

[@JulianIlett]

Yes it would :)

[@umxrr8677]

Hey julian, i wanted to know which program do you use to design pcb's and also i'm trying to remake a battery charger the old one is too messy so i'm trying to convert it into a pcb basically i have tried a few pcb designers and all of them don't have the Diode 1N5400 which i am trying to use. Your help will be appreciated. Waiting for your answer in the next interesting video

[@JulianIlett]

I use EasyEDA

[@MasterIvo]

would there be a Bolder solder?

[@gcewing]

Beware of cold joints from your colder solder. Choosing to use the older solder may be wiser, if not bolder.

[@sdgelectronics]

Very nice, thanks

[@HazeAnderson]

Looks awesome, I am sure it will sound great too. The only thing I can comment on is the strain relief from the jacks and pots -- I would mount them and wire them to the board with crimped connectors. But let's see how this turns out, I am sure it will be just fine. :)

[@frankowalker4662]

There is older solder, there is colder solder. But there is no older colder solder!

[@jlucasound]

"Analog Playground". Priceless. And I thought I was clever.

[@AJB2K3]

JST is nice because they are polarised and locking preventing loose connections.

[@peerappel2012]

mm they're just small and vulnerable. I prefer Molex 2.54 connectors

[@chefbink61]

I get all my PCBs made at JLCPCB too. They do a great job and are really fast. And really it ends up being cheaper then me making them. Though I do make some at times

[@Cadwaladr]

I have some older solder too. The rosin in it smells lovely, much nicer than the cheap solder I bought on amazon. But the old stuff is very large, too big for doing pcbs.

[@CornishMiner]

My experience using those pots in an audio project is that the metal body of the pot will need to be properly grounded.

[@thehappylittlefoxakabenji8154]

cool project Miss ETI still have the first issue somewhere !

Suggestion for a new project: solar activated blinds to keep your workspace evenly lit, perhaps?

[@Mark1024MAK]

Your workshop looks to be more or less, the same size as mine. I do have the advantage of having storage space elsewhere though.

[@jonathonbarton2936]

just an opportunity to pass on 2 ideas , self tort from street rubbish, took me 2 years to convert a KORG M1 to 12 v I built a parallel coil system that worked for 10 min. then found mini atx power supplies, with duel 12v supply,, had to resolve a ±6 mA earth loop,,anyway I make endless cables for my solar van studio, rework loads of phono rubbish cables ,specially the AV connectors with 6 phono plugs for 0 or £1,idea that you might like and promot,, got 1/4 Jack and 3.5mm Jack , got standard 9mm phono, how about a 6mm phono plug and socket , I reckon unendingly useful , do you no anyone that can MAKE 'em ,plus ,I tooling up to smash my way into my SURFACE i7 ,got 6 stereo 3.5mm sockets with 2 switching connections (not the normal 1),,, hence hot wire and therefore switch the 2 speakers as pre-amped audio out with 2x+ and 2 earth to custom headset, then hot wire the 2 camera mics and then the headset out that is sterio so having Hugh vol. and 4 direct line inputs ,they say no entry without breaking screen, not so,,,, when trying a 10 inch surface display in the store , I picked it of its mount and the rear case stayed ,leaving me holding an opened screen and attached boards um ,,it has a hidden clip system ,you need to warp the rear case to unclip it um ,,anyway it would be great to have more real knowledge like you lot tho I reckon I have great ideas Jo , trying

What about over the shoulder boulder holder solder?

[@JulianIlett]

In that case, neither older nor colder :)

They connect to ground, but the ground plane is invisible.

GREAT Vid Julian...!!! Can you put where did you get those little boxes for resistors??? They look beautiful for storing...😊

Vocoder is looking good.

[@NeonblueIndustries]

Hahaha. somone had a strong coffee this morning! haha. Great vid as always man. Very interesting project. I would love to see a demo of what it can do!?!!?

[@robertharker]

You might want to look into a summing amplifier curcuit which puts an equal value resistor after each input but before the op amp itself. This avoides changes in level of one input affecting any of the other inputs. Here is a good tutorial on the subject: www.electronics-tutorials.ws/opamp/opamp_4.html

[@TheChipmunk2008]

Good for using SWG ... the real gauge of wires.

[@duncanx99]

I once had a girlfriend who exactly matched your description of those first two solder joints. An effect of the rationing, I suspect...

Okay, but why spin the boards to take 8-pin DIP sockets and then have to spin extra adapter boards for the stereo headphone jacks? Why not just spin the boards to take the headphone jacks directly?

[@russellhltn1396]

He explained that in a prior video. The next time he goes to order jacks, the pins are likely to be different. Rather than redesign the whole board, he only has to redesign the adapter board for a different style jack.

Look forward to hearing this beast, it's design comes from a time in history when audio quality was far higher than the average consumer electronics of today.
