Month: April 2014
Using sept 2013 recipe base with salt additions:
- 6kg Gladfield pilsner malt
- 300g gladfield gladiator malt
- 300g gladfield medium crystal malt
- 7g Gypsum
- 2g CaCl
- 20g 6.7% motueka – first wort hopped
split half in mash, half in sparge water.
pH not temp adjusted, reading 5.2
Ph measurement was spuradic – reading current from the mash tun – needed to draw off sample to read
Mashed at 66c for 90 mins, mashed out to 72c, sparge ater 76c
pre-boil gravity – 1.074 ! – Need to lower
3l – IPA boil – top up with 500ml water
3L – New world boil – top up with 500ml water
Add 2L 55c water for to main boil temp dropped to 96c
match sparge pH 7.7 to 5.28
added .6g citric acid to bring to 5.1

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

Carbed with 2g syrup;
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.

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!
