About me (click for add. Details)

Since i was born in a migrant family, i barely had access to any tinkering tool.
I lived with my sister ~100€ each month for food, while my mother worked during the week outside of my hometown.
Hence, i pursued the activities that i found to be enriching. In friends, videogames or sports. I 'diffused' through the 'free' activities and hobbies in my hometown, while at home my drunken father and later silence waited.
So, you cannot take the excuse of your origin.

One guide to tech was for me to meet a lot of friends during my educational path, as well as helpful clear guides (teachers, local people or the internet).

I didn't understood some sentences, because i listened vietnamese, while i spoke german to my mother.
Until today, I cannot speak vietnamese nor does my mother speaks clear german.
> Households with educated parents doesn't convey however as well encouragement to the tech domain, as you can regard from the history of the disabled son of Hilbert (mathematician). This doesn't mean disabled individual have to be treated disrespectfully.
This also means in another domain, that a politician speaks about tech, while not understanding tech, which is totally fine as long the technician might not take advantage of this.

Honestly Education isn't fair, but it matters a lot to have a string of good willed person to clear your noise, shows you an helpful source or guides you through the jungle.
Good work will never die.

Tech Analphabetism isn't surprising. It is the result of time, people & most of all language.
The most weird thing is while Ham Radio Clubs are overly male dominated, the Astrophysicists are overly female dominated. (also in history)
I also want to make clear, that the most gifted mathematician isn't always the best guide and i'm honestly by far not perfect.
Anyone can learn tech with the own effort, right people & tools.

The intension of this sub-website is to show you my projects and path, which might turn to you as an helpful reference.

Reverse Engineering a Circuit.
Next to it, is in the back a Memory Circuit. It lights up, whenever memory is stored, like in your brain. ;)
This is considered one of the first projects when I visited a friend of mine, who introduced me to circuits.
I had the task to find the mistake-/error in this circuit. Like my own mistakes.
So I drew it out and measured from A to B.
Until I attempted to finally solder it.
Guess what. >It didn't work. ^^

Notable, that the hand-drawn CPU is a Reimplemented Open Source Project from a Student. (Video)
I redrew it.
There is also the Ben Eater Circuit, the Mr.FPGA, Tools or Radio Kits. :) (Circuit board soldered at a friends place for his coffee machine project. He - a wonderful friend - taught me most things, for which I am eternally grateful.

Noch folgend.. bzw. siehe Elektronikreise. (Einblick:)

(Die beiden Rover, die Flack und der TEM sind nicht von mir. Das Damenspiel ist auch vom Verdun Museum)

, It is important to gather your tools.
F.e. Heat
Solder iron for single spots. (Technique for creating a bulb and slideing through a line of fine metal contacts. This requires Flux.)
(De) "Solder Wick or Pump for Desoldering single spots.
Heat plate & Stenceln/fluid container dipping for faster Soldering Areas.
Heat blower for Desoldering Areas.
Similiar to the measurement devices:
Multimeter for single spots. (+ Highvoltage, or f.e. clamps)
E & H Field Probes for EMV (Surfaces of single spots)
Heat Cameras (If you have the Cash.) for the whole Surface Area.

Oscilloscope for RMS single spots. (Contains all spectrums of the signal. So you might find 2x signals that are added and shown in the Frequency Spectrum)
Multiple Probes (Careful for Differential. If you probe with 2 at the same time, you might create a shortcut and ruin your oscilloscope. Make sure it has a Differential!)
Test Devices(From Cheap- Expensive for THT or SMD) and Cabines for the whole Circuit Board Test on multiple test points (Expensive)

Single spots < and >Surface Area might sound trivial but apply it practically when your head is loaded with the problem indication. (Person: ' The light sometimes turns off and on' + the whole landscape of the unknown board + choice of applied tools for your crafted solution).
A map/datasheet is the key to every build or repair.
(My these: after 4 new, you forget)

Sometimes magnification lens or a third hand is required.
As well as a lamp. As well as polarizing lenses. (You can read part numbers faster if you watch through a polarized lens to the chip.)

The right mechanical tools are important as well.
Tweezers with a millimeter gap might look to you unnecessary, but if you grab not a cm THT unit, but an mm SMD unit, it will show the difficulty. Not only it will land naturally at its backside due to its low weight during your natural hand placement, but some parts are thin and others are brittle, which contains high charge. > (isolation wrist on GND for the hand for smaller parts, > Use an ESD Mattress) + handle the tweezer precisely
This showed me for the first time, that you pay for the quality of high-precision tools of clockmakers or professionals. (materials property + precision)
You can use a good twizzle during soldering many wires, while a good twizzle wouldn't absorb the surface tension of the metal fluid solder point (temperature) and a bad one does. Use then the soldering iron with the good twizzle to press the small stack of wires, thus you don't risk minutes or hours. (3rd hand needed + during 370°C. Project on an embedded device on a small pin distance 1-2 mm. So the solder joint might distribute to the other point and obviously, you have to remove it then afterward. Therefore use a stencel and the heat plate for the area. > Easier. But buying + shipping + preparing/producing the metal template does require again preparation and ++)

There is a minimum for fixing mechanically the device and you have to balance the complexity with the cost & time. If it is cheaper to buy a new part, do that.
If you like to try the challenge, do so.

You cannot just think about deriving a physical equation. You need a hands-on measurement for faster execution of your task. (Unless you enter the realm of higher energy scale (CRT's, which i wouldn't touch, as well), where a fine review process and error prediction are handled, designed, or thought. TopDown /= BottomUp)
> The bottom line is for me, theory & practice.
> The Feeling for the units & errors to discuss it precisely across participants.

During university, I haven't learned some practical tricks f.e. for each measurement device are different modes for detecting an error. The basics have been taught. But when you build your specific circuit, you forget these principles very fast or they aren't in your language memory, on the performing task. Nodding the theory in the lab, but actually applying it to the completely specified circuit in practice is completely different. It has to be seen and linked.

A bitset for a mechanical screwdriver helps with screws, while an electric one saves you hours of lifetime.
There are many more mechanical details for connecting two parts with your available tools (Rubber, Glue, Screwing, Soldering, etc.), which obviously wasn't the first thought for a task, which wasn't considered in the electric domain. (++extra Tools, which weren't in your bought lab)
Straightening wires, Quality of bending THT contact boards, Extra isolated layer on the electric board during transport (which led to not functioning. Use a teeth brush), or having reference units for drilling, screwing, drawing, or else are these tiny details, that I stumbled and wondered during practical appliance.
Now scale that towards a bigger project. Hence you have to run through these beginner projects in some sense to experience these faults & physical 'resolution' issues/errors. The first thing is a good precise solder iron (the tip) & the other thing is your own handled precision.
Thus, a Hobbyist must think broader than Electricity in the other domains. And I haven't started with the software yet. (Regulation parameters which aren't obviously optimal, when you modify your circuit on capacitors or length, different firmware, OS, specified Test Boards to only being able to test the circuit (in handheld video consoles the protection), not available software at all (Infineon Chips. So no datasheet obviously, but listed. or very old 1970 chips) ... .
One malfunction of a screw (you brushed the alloy too much) does actually change drastically the thermic region of sockets or units. (brushing off the dark burned pulverized parts)

There are many of these details, during tinkering & a non-tinkerer cannot predict these errors. Thus he has to learn it practically to get a sense of feeling for the physical units. (temperature and voltage mean more)

Experienced tinkerer coat the unit and heat up the unit just to see the faster evaporation of the alcohol. Thus the error might be in this location (However Sender and Receiver)
Others see a spike in the Oscilloscope, which indicates, that 'probably' there is a data communication. It is faster to pinpoint the issue rather than to search & recheck the data sheet of the data protocol.
These tips might help you. (spontaneous written)

> I have learned a handy of these tricks from a great friend.

Sachdienlicher Hinweis: Unvollständig und nicht Bspw. auf "dQ/dt " sondern lineare "ΔQ/Δt" definiert.
Die Diffusionsgleichungen werden noch differentiell komplett eingearbeitet. (Herleitung und Schrödingergleichung + Autoren)
Das benötigt leider noch Zeit..
Für die Tabelle ist die folgende Eselsbrücke hilfreich

”Strom", "Wärmestrom", "Volumenstrom", "Lichtstrom" - Kraft. Drehmoment
equival.: "Spannung, Temperatudiff. Druckdifferenz, "Raumwinkel"- Geschwindigkeit (Weg), Kreisfrequenz (Winkel)

Mul * Leistung * * * Leistung(Energie) Leistung
Div / Widerstand Wärmewid. * -Lichtstärke Masse * Zeit Trägheitsmoment

Anhand von "Strömen" und "Spannung" kann man multiplizieren oder dividieren. • Dadurch kann zwischen Energiesystem (Motor oder Gen.) die einzelnen Leistungsumsätze bestimmt werden.
• Dadurch kann die Auflösung in das aktuelle Sprachsystem (Mathe) übersetzt werden. (Sensor, Motor)
• Dadurch kann die Empfindlichkeit in das jeweilige System (Mathe: Binär)übersetzt werden. (Sensor, Motor)

Bspw.: Aus Material und Raumkoordinaten: R = ρ * l/A = U/ I kann zu jedem System der "Widerstand" bestimmt werden. (Demnach das Material)
Equivalent zu den Energiespeichern.
"Carrier" • I = Q/t • • Q/t • • • V/t • • • • Photonen • • • • • F = p/t • • • • • • M = L/t

• Q.. ist die elektrische Ladung
• • Q ist hier die Wärme "Heat"
• • • V ist hier das Volumen
• • • •
• • • • • s ist hier der Weg
• • • • • • 𝜑 ist hier die Winkeldifferenz.

Energiespeicher: C= ε * A/d

Hier wird jetzt viel Text vorgestellt. Im Grunde muss nur Strom, Spannung, Energiespeicher, Leistung und Energie verinnerlicht werden. Aber es sind im Grunde alles nur Ausdrücke für "Wege" mit dem "Wert" der Kraft (Menge).
Die mathematische Dimension ist die eigene Beschreibungssprache, in dem in jedes Symbol ein gesamter Sachverhalt ausgedrückt wird. Bzw. zu dessen Kontext für das Parsen. (Vgl.)
Es startet von der Mengenlehre. (Ausführungen folgen bzw. Vervollständigungen.)

Eigene Interpretation:
Der Ansatz für die Verallgemeinerung in der Mathematik würde aber vernachlässigen, dass eigentlich jeder Beruf eigentlich diese "Mathe"-Sprache beschreibt.
Wir reden nicht von H20, sondern Wasser. Wir reden von Früchten und Karten, nicht von der molekularen Zusammensetzung oder der Boltzmannkonstante. (im Alltag des jeweiligen Berufes.)
Von der Biologie, Chemie, Physik, Informatik, Mathe bis zur Gemeinschaftskunde, Ethik, Geographie und zur Kunst, Musik, Sport, gibt es eine Sprache und eine Geschichte.
Jeder Logikpfad in einer Fachdomäne begreift also die Welt anders und die Synthese beschreibt die mannigfaltigen Kombinationen.
Ich liebe und verdanke so vielen Begegnungen, die mir erlauben deren Ansichten zu sammeln, zu adaptieren und repräsentieren.
Können wir das Leben beschreiben, wenn wir alles auf Mathe münzen?
Nein, darum sind die Einheitenkonvertierungen pro Objekt zu krumm,
und die visuelle Interpretation unverständlich.
Gar unsere Kausalität von Menge:
"Das ist ein Punkt" zu überbestimmt..

Die "Zahl" wird in jedem Beruf angewendet und wir teilen uns die Zahl in einer verständlichen Sprache.
Wir bauen ein unfälschbares Maß (von Liter auf Platin - harter Prozessschritt -, unreproduzierbare Energien, sowie eine Überbestimmte Menge (Kryptografie).
Die Kryptografie und die Interpretation jeder Stelle sind nicht binär, dezimal, 24x Buchstaben, sondern ableitend aus allen Einheitenkonvertierenden Mengen... (Max. geschätzt Rayos Number)
Jeder Mensch ist ein Unikat und keine leere Zahl.
Das Leben dreht sich nicht nur um Mathe, sondern
Das Leben dreht sich, um jedermanns gemeinsamen Entdeckung.

Hint:
The association 'faranto e.V.' inspired by the name 'esparanto' already originated 2001 by couraged students, when i was in the primary school - learning numbes, language, singing and sport. I'm grateful to be part of this history.

This doesn't mean, that i did it alone. I was only one little piece from all the people, accesories and community to help & test my leadership. I learned alot from all the friends & people, i met.
