RSteckCase

RSteckCase was designed by hobby brewer Ralf Steck. 3D print files are in Gehaeuse/RSteckCase/RSteckCase.zip.

The housing is split into two assemblies: base and cover.

Overview

• Brautomat controller with integrated display

• Mash kettle heating via IDS5 panel (switchable between front panel and external control)

• 2x SSR relays for boil and NACHGUSS kettles

• PWM speed control (MOSFET) for agitator

• 2 relay outputs (one currently not routed outside)

• 3x DS18B20 sensor inputs for all three kettles

The nickname "Porcupine" comes from the many connected cables sticking out in all directions.

IDS conversion and 3D print parts

• 4-pin on/on switch for IDS5 conversion: Amazon

• Matching plug from forum member Jojo5

• Printed parts: raised carrier, converter holder, relay holder, front panel cover, handle

Wiring and power

• 12V input at rear bottom center (agitator supply)

• 12V feeds relay board and MOSFET output

• After conversion: 5V for SSR inputs, Innuendo board, relay board

• Wiring clamps example: Lever Clamps

High-voltage area and cooling

• 230V section is located in the cover and shielded

• Power path: IEC sockets -> SSR -> Schuko sockets

• Heat sinks can reach around 60°C during brewing

IDS plate conversion summary

• Install 4-pole on/on switch at front right (bottom side)

• Wiring:

  • middle row -> cable to heating element

  • front row -> 5-pin cable to Brautomat

  • rear row -> cable to front control panel PCB

  • all three GND lines soldered together

• Switch forward: front control panel active

• Switch backward: Brautomat control active
