No one answered. Is there someone who had recovered all of the project PID mocha Zerba because the pdf of the first post does not give details on the hack? thank you :
Thank you for the pdf but is it possible to find the full version? It lacks detail and it is not possible to write Mocha Zerba because he is a ex member.
.
I tried downloading them but a recent re-open left me with garbage.
My rememberer doesnt have a PID memory in storage--only a rheostat to decrease the heat put out by the element so that the machine didnt cycle off/on but could be turned down to manage the temperature gradient.
There was a lot about his experimenting to come to the final design, and in the end I didnt think it would have been worth the trouble.
I suspect a nice cooler would be a better option--I must get busy and make one for a decent trial.

So one can see the triac cuts the power to 80% (the specs with the triac say control from 0 to 90%) so one definitely needs to have a switch to bypass the triac during rampup to FC (as the CoffeeTime article has). I have yet to wire that in yet.

Or move to the stage 2 mode, by using a lower voltage heating element. e.g. in the UK our Voltage is 240V, but I have removed my 240V element and use a 230V. This allows roasting in almost any voltage range I am likely to get in the UK......my Variac has been unused since I completed the stage 2 mod.
One of our member in France has the stage 2 mod running using a 220V element in a 230V country.
It also allows the judicious use of "overboost" in very cold weather. This is running the Gene to draw more than 1250 W when its very cold.
I can assure you that if you are drawing 1360W routinely, 2 things will happen.
1. Your heating element life will be quite short and its not good for the Genes structure
2. Your roasts wont be so good...its just too hot and quite a steep temp gradient in the roaster.
Also check your dimmer, because its sapping an awful lot of power. In addition the Killawatts, power meters whatever here in the UK can show some variance, might be worth double checking to ensure yours is accurate.
