Hi Stefan,
In my Photo album I have one picture, is this a thermo ∗device∗ that
can be used for the schematics you will provide? I have found the
optocoupler in the powersupply that switches the triac for the lamp.
Now only the thermostat and a slowmotor is needed :)
You say SLOW, taking the diameter of 16mm into account, how many rpms
do you think is needed ?
I will provide pictures of this ∗adventure∗ with reports of ∗quality∗
of the TT. Looking forward to this project.
