Sand Powered Mechanical Hammer / Martello Meccanico a Sabbia

This model is my free interpretation of the mechanical hammer designed by Leonardo da Vinci.
After putting sand in the upper container, its fall causes the paddle wheel to turn, which in turn drives the mechanical hammer cam.
NO GLUE is needed for part assembly!
2 models in 1! The crank operated mechanical hammer + the sand powered mechanical hammer.
Recreational, educational, enjoyable!
Ideal gift for inquisitive and smart people…


Thanks to the RIP Technology, no glue is needed in order to assemble the model… and you can assemble, disassemble and reassemble the model over and over again.
Funny!

Grazie alla tecnologia RIP l’assemblaggio del modello è effettuato senza colla… e potrai quindi montare, smontare e rimontare il modello più e più volte.
Divertente!

UPDATED AND CORRECTED VERSION AVAILABLE
VERSIONE AGGIORNATA E CORRETTA DISPONIBILE

The boxy-Christmas Set

Original 3d models by PolygunShoot (www.cgtrader.com) modified and adapted at paperPino’s workshop in Trieste (Italy).

These paper models are easy to build as they consist of boxes, boxes, and more boxes… For best results, I suggest to use 200 g/sqm cardboard.
Enjoy, and…

Merry Christmas and Happy 2020!

Ponte di Leonardo / Leonardo’s Bridge

Di tutti i progetti di ponti di Leonardo, il ponte autoportante è certamente il più geniale nella semplicità della sua struttura e costruzione. Non sappiamo se questo ponte sia mai stato messo in pratica, ma non è difficile credere che una costruzione così modulare, estremamente facile da trasportare e da assemblare, debba aver incontrato un grande favore da parte dei signori del Rinascimento che erano sempre alla ricerca di nuove tecnologie da utilizzare per scopi militari. Si tratta infatti di una struttura composta da semplici travi a sezione circolare, che vengono assemblate senza l’uso di fissaggi o giunzioni. Una volta assemblato, il peso del ponte è sufficiente per esercitare la pressione necessaria in modo che le travi longitudinali – chiudendosi come un paio di forbici – blocchino le travi trasversali in posizione, evitando così il collasso della struttura. Maggiore è la pressione sulla parte superiore di questo ponte, maggiore è la sua stabilità. (da www.leonardo3.net)

Of all Leonardo’s bridge designs, the self-supporting bridge is certainly the most ingenious in the simplicity of its structure and construction. We do not know whether this bridge was ever put to practical use, but it is not hard to believe that such a modular construction, extremely easy to transport and to assemble, must have met with great favor from the Renaissance lords who were always on the lookout for new technologies to put to military use. It is in fact a structure composed of simple circular section beams, which are assembled without the use of fastenings or interlocking joints. Once assembled, the weight of the bridge should be sufficient to exert the necessary pressure so that the longitudinal beams – closing like a pair of scissors – lock the transverse beams in place, thus preventing the structure from collapsing. The greater the pressure on the upper part of this bridge, the greater its stability. (from www.leonardo3.net)

Paper layering bathymetry of South Adriatic

It’s time for experiments…
Paper layering bathymetry of South Adriatic,
the deepest sub-basin (1250 m) in the Adriatic Sea.

Medium: Folia Bringmann 300 g/sqm painted with Epson Stylus Photo R2000

 

The South Adriatic is the deepest sub-basin of the Adriatic Sea, in the Mediterranean. It is a crucial place where the thermohaline circulation of the Eastern Mediterranean originates through a mechanism called “open ocean convection”.
