Sweet Dreams / Sogni d’oro

On 16 September 2005, the automaton Sweet Dreams was launched on the web. At that time, it was considered the first paper automaton employing the mechanism called Geneva stop.

The Geneva stop (or Geneva drive) is a mechanism that translates a continuous rotation into an intermittent rotary motion. It is an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps. The name derives from the device’s earliest application in mechanical watches, Switzerland and Geneva being an important center of watchmaking. One application of the Geneva drive is in movie projectors: the film does not run continuously through the projector. Instead, the film is advanced frame by frame, each frame standing still in front of the lens of 1/24th of a second. (from Wikipedia)

Il 16 settembre 2005 l’automa Sweet Dreams / Sogni d’oro fu lanciato in rete. A quel tempo fu considerato il primo automa di carta ad impiegare il meccanismo chiamato croce di Ginevra (o di Malta).
La croce di Malta o croce di Ginevra è un meccanismo che trasforma un moto rotatorio continuo in un moto rotatorio intermittente. Il meccanismo è costituito da due ruote; la ruota motrice porta un nottolino che si infila in una fessura della ruota condotta (croce) e la fa avanzare di un passo. Le fessure sulla ruota condotta sono simmetriche e generalmente ad asse lineare dirette in senso radiale. Il suo nome croce di Malta deriva dalla somiglianza della ruota condotta con lo stemma dell’ordine dei Cavalieri di Malta, mentre croce di Ginevra deriva dal fatto che una delle prime applicazioni era negli orologi: la Svizzera e Ginevra sono importanti centri per la produzione di orologi. La principale applicazione della croce di Malta è nel proiettore cinematografico: il film non passa nel proiettore in maniera continua, ma fotogramma per fotogramma, posizionandosi davanti alla lente ogni 1/24 di secondo. Questo moto intermittente è realizzato con la croce di Ginevra. (da Wikipedia)

Hi Pino,
I am from Korea.
I began to get interested in automata recently and enjoy searching good automata projects to follow it and introducing it to Korea community for a maker.
Is it possible for me to translate your instructions in English into Korean and introduce your projects with mentioning your source link?
Thanks for sharing this great works ~~

Hi!
Just finished building ‘Sweet Dreams’.
Works wonderful!!
Great ‘THANKS’ for this Papermodel!
I will try WAP yet in 80%, because I like little things!
Ciao,
Susanne

Complimenti, questo automa è bellissimo!
(non solo, ma anche perfettamente progettato – tutto s’incastra alla perfezione!)
Ho appena finito di incollarlo, non vedo l’ora di passare al prossimo!
Complimenti ancora e grazie per rendere i suoi modelli gratuiti!
Una curiosità: come li progetta? piacerebbe anche a me provare!

  Grazie, Lorenzo.
  La progettazione è una cosa piuttosto lunga da spiegare. Comunque, mi hai dato un’idea. Creerò una pagina dove spiegherò il workflow che seguo nella progettazione dei miei automi.
  Ciao,
  PINO

this model is so amazing but the rolling reels is too hard i can’t finish it
but almost all of your model is great

I am in the process of building “Sweet Dreams”, so far everything fits together very well. It is very precisely designed.
The only modification I made to plans is doubling paper thickness in some places to add strength. I am looking forward to finishing so that I can turn the crank!!!
If it works will I have enough courage to attempt WITS and BIRD?

I just finished building this one, great design, and my wife really enjoys it. She even makes the “baa” sound effects while turning the crank! I had no idea this was the same mechanism used in movie projectors. Well done Pino!
