Castle pub tap

Finally upgrade from the picnic tap!
My Dad got this tap from my grandmother Ruth from the castle pub in Wales in the 70’s. It’s finally operational, pouring a green hop pale ale with the hops grown 10m away by
my neighbour Ellen.

Mash controller housing

Using Ben’s dremil I have finally housed the raspberry pi in a recycled hard disk box. The power sockets came from a ups box bought from a computer recycle place.

Leah kindly dropped off 3 boxes of pears from her grandfather.

20L yield from the juicer.

Also used Ellen’s steaming juicer, approx 2L of syrup, plan to back blend this after fermentation.

Wrote off another hydrometer, gravity 1.040

Stc-1000+ updated open source firmware

Re-programme an stc-1000 v1.0 with customer brewing firmare, that supports temperature gradient profiles.
The STC-1000 is a dual stage (heating and cooling) thermostat that is pretty cheap to buy. I (and a low of fellow homebrewers) use them to control the fermentation temperature of beer.

The goal of this project is twofold

To create the means to reprogram the STC-1000 with a custom firmware
To create a custom firmware, suited for fermenting beer
The first goal is achieved by using an Arduino UNO with a sketch to act as a programmer, and the second by using the SDCC compiler and GPUTILS.

Download by visiting the releases page and start by reading usermanual.pdf

Features

Both Fahrenheit and Celsius versions
Up to 6 profiles with up to 10 setpoints.
Each setpoint can be held for 1-999 hours (i.e. up to ~41 days).
Somewhat intuitive menus for configuring
Separate delay settings for cooling and heating
Configurable hysteresis (allowable temp swing) from 0.0 to 2.5°C or 0.0 to 5.0°F
Approximative ramping
Button acceleration, for frustrationless programming by buttons
Cheers!
