The Secret Society of Lathe Trolls

From newbie to newbie,

Rotatory spyral focusing lenses(or similar device)+Ligth variable resistor(LDR)+voltage to frequency converter+amplifier+cutterhead.
The light capturing device and the turntable must be conected somehow...

Hello! Wow! Great! So, you mean something like a TV frame, but spiral instead of straigth lines? The lathe to cut that must have extreme accuracy...or maybe some synchro signal recorded in a locked groove and feed back into the system via the playback tone arm... An analogic version may be possible ...

Spanish thread! I hope is not bad manners posting in other language than English. Hola! Yo vivo en Valencia, y me estoy intentando construir un cacharro desde cero, pues no encuentro nada bueno para restaurar. Los Granadians tocaron aquí el Viernes, pero me los perdí, pues curro los fines de semana....

Wow! If Heaven looks like this, I promise to be good the rest of my life!

Hi! I've got Nothing interesting to write....yet!
Thanks Trolls, great board!
Fela.
