My echo chamber JCechoFDS

Hello Didier

Do You think it will be possible to buy the printboard ?

/Bertil

Hi Bertil,

I don't think so. A member of our French forum is going to make a limited batch of 20 printed circuits at cost price (€5 each), but all of them have already found takers, and he doesn't want to make more. So if you don't know how to make one, you'll have to find someone who can do it for you.

A trip to Maplins will get you a copper board with etching gear. Our lass makes great etching fluid --a nice pan of scouse.

Easier said than done.

You're not wrong there Eric !!

Looks ball aching and I'm not surprised production's been halted by our friend JeanClaude.

It's relatively easy once the board is computer designed and proven, it can be made out commercially then at a reasonable cost.
I've done it.
To make one at home, with an etching pen etc is very tricky when using 16 pin ICs etc and therefore tiny tracks.
I've also been there, done that , it's a black art.
I'm contemplating making a much, much simpler echo than Jean Claude's and may well make a proper PCB after doing a prototype.
A thousand thanks to him for the spark, the fundamental notion of using one echo chip per recording head. Magnifique !
I still have a certain amount of equipment having done this sort of design and construction in my time as an electronic engineer , heated bubble etchant tank, wash tank ,ultra violet photo developer etc, but to contemplate making even a few PCBs in this way is a no-no for me.
Here's a PCB I designed, this was sourced out after doing the prototype.
You can just make out my name and old phone number on the right hand side.

Hello

Excellent !

There's a commercial gap in the market here and I know JeanClaude doesn't want to market his design as a retail unit but offering it for members' use along with a mention of the designer. However Jean Claude needs to protect his product in some way even if not built by him but to his specification.

The circutry and hardware, if the market is large enough, can be sourced to China or at the very least the PCB can be manufactured here in the UK and included in kit form as Maplins do for electronic kits. As for EFTP presets, ask yourself who uses all the patches built into the echo?

I too was an instrument tech in my early days so a soldering iron or an AVO are no strangers to me.

Be careful mon ami, keep your business head on and think like a dragon in Dragon's Den.

Kerching !!!

There is not a market large enough for such a product to think of sourcing production in China !
Keep in mind that it's only a labor of love from Jean-Claude who was missing the smell of a hot soldering iron !

Too right Didier, there's no money making here.
Cheers Jean Claude !
