Hi teemuk,
Your work in denim is very very nice, as well as the idea of lacquer coating, for protection.

Have made another version, with the front in wood, which gives a nice "old fashion" look.

Here you have it...

Thanks svstee !,
In case I can found the jack indicated by teemuk, this would be easier (also reducing the cost, since that jack would have 2 functions), however, I've seen that, for headphone's usage, it would be necessary to add a resistor to the + pin, in order to attenuate the output and, in this case, the resistor would also affetct the spkr's output power...
I'm in a crossroad...
Thks to all, I'm learning (and thinking), which is good !

Hi Teemuk !
Many thanks your suggestion, I'll look for this kind of jack.  :tu:
I do live in a small town, maybe I have to go to the "big city" to buy it...  >:( who knows !

J M Fahey, good night
Maxi-Rubber is, in fact that "rubbered" paint used inside car's trunk (under the carpet), and below the cars, for protecting against stones spitted-out by the car tyres. Hope have expressed well... (se você estiver no Brasil, é fácil de achar em qualquer loja de tinta automotiva, o nome comercial do produto é "batida de pedra").
I guess the product can be found all over the world, obviously, under different brand-names.
In case you have additional questions, pls don't hesitate in asking me !

svstee, good night
Many thks for the headphone jack's tip. Is this schematic supplied with "Storm Software" or you created it with it ?
As far as I can see, this would give me the 2 outputs in paralell (maybe I'm wrong). do you have a similar one that disconnect the spkr ?
Sorry for being so abbusive  :-\ ...
And thks once again !

p.s.: JMFahey, acabo de ver que estás en Argentina. decime si necesitás te hable mas sobre el Maxi-Rubber, ok ?

Hi Guys !,
I'm absolutely new on electronics, but decided that Ruby circuitry should not be a difficult project to do, therefore, started to work on it.
First, I made a proto in a used olive oil box, then, improved little by little until reaching the final stuff I post here:





The weight: 350Grs (without battery)
Dims: 14 cms (w) x 10 cms (h) x 7 cms (deep).

I'll post some photos of the back, as well as make a short movie, so you can hear it.
The case was hand-made in wood, painted with Maxi-Rubber first, and a bi-component varnish for extra protection.
Ortophonic fabric was used for hiding the speaker (3", 8 Ohm) and can be powered by a 9V Battery, or a 12V transformer, according to user's preferences. 

For next builds, I expect to introduce e few mods, such as a) Tone pot and b) headphones jack (still wondering how to disconnect the spkr when pluggin-in the headphones...).

Screws are not pretty at all, but I've already found another alternative for improving the finishing.

Hope you like, and suggestions/ideas are always welcome !
See you.
