Senseo GPIO Button Example
We’re now in the perfect place to briefly explore something on the side, apart from the intricate MCU electronics. With the tactile switch, we found the object that connects a w...

Reflections on Quality ZMM #1
I recently read the book Zen and the Art of Motorcycle Maintenance and took some notes along the way. This is an attempt to make those more coherent...

Abundance at the Individual Level
The idea of a fast for me is to trim down the fat. Not just around the body, but in the brain as well

PCB Microcontroller Subsystems: GPIO
Next in the MCU we encounter the GPIO - General Purpose Input Output pins. We’ve seen the CPU, which is essentially millions of flip flops connected via combinatorial logic and...
-
PCB Microcontroller Subsystems: CPU core
We’ve now seen quite some fundamental concepts from which most other elements are also built. We’ve seen MOSFET, CMOS logic, extensions into combinatorial logic, feedback, latch...
-
PCB Fundamentals 6: Clocks & Flip-Flops
We’ve now seen quite a few basics, from combinatorial logic where basic circuits create a stable equilibrium dependent on current states, to memory and the way latches are used...
-
PCB Fundamentals 5: D-Latch
At the end of the sequential logic section, we saw the SR latch and how it provides a way to overwrite memory created by cross-coupled inverters. Now the problem is that such an...
-
PCB Fundamentals 4: Combinational v Sequential Logic
Now that we can build logic gates, the next question is: how do we use them to make useful decisions and computations? We’d like to have a machine react to inputs and perform th...
-
PCB Fundamentals 3: CMOS Logic
We've now seen the most important building block for most of the electronics in our Senseo machine, so the next step is to explore how it's utilized so effectively. We're theref...

PCB Fundamentals 2: MOSFET Transistors
I mentioned that MOSFET transistors are the reason this chip can achieve so much yet be so small. Now a MOSFET is like a tiny switch. It has three legs where drain and source co...

PCB - Printed Circuit Boards: Fundamentals 1
Let’s now start with arguably the most intricate sections, the ones exploring printed circuit (or wiring) boards. In its essence, it functions as a fixed path for components to...

What is Plastic?
While writing on the PCB Senseo section, I went back to an old text I wrote exploring what sand is at its base, as it was relevant in the discussion on Fiberglass. Now the other...

Senseo Boiler: Brewing
We then lastly also have the stub that looks like a chimney (Nr. 2) in the picture at the beginning of last post. This isn’t a chimney, however, it’s the hole where the water le...
-
Senseo Boiler: Safety
If we look on the image with arrows, we see some components that haven’t been identified yet. We’ve already seen the NTC thermistor (entering the side), the two red terminals, e...

Senseo Boiler: Sensing Temperature Part 2
This NTC thermistor for the boiler of the Senseo machine is placed on the control board in a series of two resistors. In fact, it’s the second resistor in that series where the...
-
Senseo Boiler: Sensing Temperature
The obscure white wire entering the side of the boiler and having a long metal pin to it, is the temperature sensor of the Senseo (See both picture on the right and open boiler...

Senseo Boiler: Heat and Electricity
This next chapter is one I’m very much quite interested in, as truly the only way I can imagine making water heat up is by creating a fire and putting a pot of water from a stre...

Senseo Electricity Basics 3: Grid to Wall Socket
To bring it all together, we can now look what happens from the point the moving electrons leave the power station, to the point it comes out of my wall socket. First, we’ve see...
-
Senseo Electricity Basics 2: Generation
I think the most interesting question that may not be relevant to the Senseo machine is that of how electricity is harnessed from nature. I’d say the easiest way to do this woul...
-
Senseo Electricity Basics 1
Electricity is the most straightforward element, but essentially I could write a post on this topic in and of itself, purely for considering where it comes from and how to go fr...

Senseo Prelude
A thought exercise I’ve been engaging in since I was a little boy is that of the time machine game: what if I was teleported back in time some 500 years, or better 5000 years? ...

On Self Preservation
One might imagine the self as a sort of blubber entity in outer space representing a planet. Any other being we interact with might then be another blubber entity, and whenever...
