Bene oggi ho quasi terminato

Inscatolare il tutto non è stato semplice vi posto qualche foto
Come vi ho accennato ho deciso di svincolare elettronica dal blocco meccanico.

Quindi ci sono dei connettori sull' elettronica e sulla parte meccanica











Servirebbe un contenitore un pelo più grande circa 2 centimetri per ogni lato compreso altezza
Ma alla fine sono riuscito a farci entrare tutto

Certo appena qualcuno risucira a implementarci una tastiera piatta key 4x4
il costo e sopratutto ingombro avra un notevole miglioria ma gia cosi non è niente male

Se in questa settimana riesco a finire tutto a breve vi postero il video del test di cotta.

G'day everyone,
I just want to say to the people that PM'd me, sorry I haven't replied, just over a year ago my 5 year old daughter suffered a massive seizure and as a result of the brain damage that occurred she has cerebral palsy, I'm not being rude I just don't have the time to reply.

regards steve

I finished reading through the is complete post as well as the Braubushka site and have decided to build a hybred system with a jacketed kettle to provide insulation during the boil and cooling with our an external chiller. To do this I am going to have a kettle custom built. This is where I am looking for some final advice.
Question 1. I remember there was a guideline on the ratio between kettle height and diameter.
Question 2 I want to be able to brew 5 gal and 2.5 gal batches so I realize I will need 2 malt pipes. Could someone please reply with a recommendation on volumes. Since I am custom building kettle I would like to have the option to brew a range of gravity beers.

Thanks in advance.

Very interesting modification would be nice to control
both the pump but especially also the electric resistance in PWM
I saw this card that uses a Triac what do you think?

In Italiano

Molto interessante la modifica sarebbe bello comandare
sia la pompa ma sopratutto anche la resistenza elettrica in PWM
ho visto questo scheda che usa un Triac cosa ne pensate ?

Hi Savio
The SSR typically used to control resistance alias solid state relay are basically composed by a triac and an option coupler plus few other components in one single box..I practice the components of the circuit you propose

Great word in Relay SSR had led me astray
I had not seen the pattern of the SSR from what I understand
is more or less made ​​up the pattern as I posted
COn the difference that in SSR is already all nice and ready in a little box
with 4 contacts and LEDs: D
So we were right to carry on the PCB reworked
Resistance PIN and PIN PWM pump on Arduino

In Italiano
Ottimo la parola Relè nel SSR mi aveva portato fuori strada
Non avevo visto lo schema del SSR che da quello che ho capito
è più o meno composto come lo schema da me postato
COn la differenza che nel SSR è tutto gia bello e pronto in uno scatolino
con 4 contatti e un LED
Allora abbiamo fatto bene a portare sul PCB rielaborato
PIN Resistenza e Pompa su PIN PWM Arduino

Not sure about your approach..

Arduino PWM pin frequency is around 400hz that is not suitable to drive a SSR , switching and driving a resistive load of 2-3kw at that frequency will destroy SSR...you can play with internal timer to tweek frequency but I think it's better to use an analog output with a time base of few seconds for cycling

The same for pump ..or you use a pump with a pwm signal input or driving a DC pump with 400 hz signal is not exactly the best..on this case frequency too low
