My Feuerzangenbowle for cold days

This post shows you our favourite Feuerzangenbowle recipe, which is perfect for cold days.Traditionally we do Feuerzangenbowle for New Years Eve.
We hope you enjoy it. Please drink sensibly.

Here we go, we need for our Feuerzangenbowle: 2 Bottles of Red Wine, Rum (more than 40% proof), 1 Sugar Cone ca. 250g to 300g , 2 Oranges, 2 Lemons, Cloves,

1 Feuerzange, which will hold the sugar cone ( you can either buy a proper one or make one yourself, as we did - see picture. The metal needs to be long enough to fit over your pot and the side slit needs to fit onto the pot rim to hold it in place. The metal is bent in the middle, so the sugar will run down through the central slit)

Cut one of the lemons into slices and stick the cloves into one slice so that they do not go into the cup later...slice one of the oranges as well.

Put the Red Wine into a pot, squeeze the remaining Orange and the Lemon and add the juice to the Red Wine. Add the orange slices and lemon slices. heat together slowly on low heat, don't allow to boil.

When heated through, put the pot on a warmer to keep the wine warm. Soak the sugar cane with rum by holding it over the pot and soaking it carefully from the bottom,

then put it onto the Feuerzange and pour more rum over it.

Set alight and be careful not to burn yourself or others as the flames can get quite high.

Keep pouring rum with a ladle onto the sugar cone until the entire sugar cone has melted into the pot.

Remove the Feuerzange from the pot and fill up the cups (pre-heated cups would be best).

Taste the Feuerzangenbowle before serving to your guests to ensure all is fine I hope you enjoy it, Ralf

Lab 1 Material : AVR Pinout Arduino Mapping

This is a usefull mapping of the AVR ATmega 168 pins to the Arduino Pins.

Currently I'm working on the strategy and concept of the development board

Currently I'm working on the strategy and concept of the development board considering the different planed 'Inventors:Force Labs' and their requirements.
I'm having fun with the design/concept of the Microcontroller development board Let's see how it will turn out ;-)  - I decided to use the AVR MKII Programmer for the Microcontroller programming.
I'll also consider to include on an excercise on how an Arduino can be used for the programming of the Microcontroller.

Lab1 Material : Solderless Breadboards

Using Solderless Breadboards in our Labs is the best approach to provide the maximum flexibility, which allows us to adapt and change the circuits while we are experimenting and thus see if our ideas would work in a real world application.

Solderless Breadboards MB-102 connections by Ralf Fickert

The holes in the numbered columns are connected together on the underside of the board. I marked the row 1 to 5 with orange arrows to show how the holes are connected.  As you can see 5 holes a - e and f - j are connected on each side of the gap. The yellow arrows are showing you how the power rail holes (Blue ‘– ‘ and Red ‘+’) are connected. Therefore when you connect a power supply to a hole of the power rail then the power is available at all connected holes of this power rail. Power rails are located on the top and bottom of the breadboard.

Multiple breadboards can be joined if required to provide more space for experimenting.

We use the Breadboard Model: MB-102 (Ever-muse electronic) within our Labs:  

• Ideal for high frequency and low noise circuits
• Interconnect any components with 20-29 AWG (0.3-0.8 mm) wire
• Special designed spring clip over 5,000 insertion cycles
• Specifications: 830 points
• Size: 16.5 x 5.4 x 0.9 cm 
• Net weight: 77 g

I hope this is useful for you,
Ralf

Lab1 Material : Microcontroller ATmega168 Pinout

Microcontroller AVR Pinout for ATmega168 by Ralf Fickert

Here is an extract from the Atmel datasheet for the ATmega  48A/PA/88A/PA/168A/PA/328/P

Please follow this link to access the complete Atmel datasheet document:

Atmel-8271IS-AVR- ATmega-Datasheet_10/2014

VCC

Digital supply voltage.

GND

Ground.

Port B (PB7:0) XTAL1/XTAL2/TOSC1/TOSC2

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Depending on the clock selection fuse settings, PB6 can be used as input to the inverting Oscillator amplifier and input to the internal clock operating circuit. Depending on the clock selection fuse settings, PB7 can be used as output from the inverting Oscillator amplifier. If the Internal Calibrated RC Oscillator is used as chip clock source, PB7...6 is used as TOSC2...1 input for the Asynchronous Timer/Counter2 if the AS2 bit in ASSR is set.

Port C (PC5:0)

Port C is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The PC5...0 output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running.

PC6/RESET

If the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical characteristics of PC6 differ from those of the other pins of Port C.

If the RSTDISBL Fuse is unprogrammed, PC6 is used as a Reset input. A low level on this pin for longer than the minimum pulse length will generate a Reset, even if the clock is not running.

Port D (PD7:0)

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port D pins that are externally pulled low will source current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running.

AVCC

AVCC is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC through a low-pass filter.

Note that PC6...4 use digital supply voltage, VCC.

AREF

AREF is the analog reference pin for the A/D Converter.

ADC7:6 (TQFP and QFN/MLF Package Only)

In the TQFP and QFN/MLF package, ADC7:6 serve as analog inputs to the A/D converter. These pins are powered from the analog supply and serve as 10-bit ADC channels.

All the best,

Ralf
