I've been COOKIN

SMD (Sonic Must Die) au notes:

Silver hurriedly comes to Shadow and Rouge with a dilemma. Silver has researched the future timelines and discovers that in all of them where the world ends, Sonic has lived out his natural lifespan or had been killed by Eggman. There is a possibility they could save the future but they have to do something drastic. the only option they have left at this point aside from a miracle.

Sonic has to die, and they have to kill him.

Shadow; having formed a genuine bond with Sonic at this point, is distraught. After learning to give humanity a chance from Maria, he has to go and lose another friend for the sake of saving the world. Ultimately he agrees to it after some months of thinking.

Rouge isn't as on board with it as Shadow and Silver are, but she's willing to lend a hand where she can. She knows it's the right thing to do, but that doesn't stop the feelings of betrayal.

One way or another, they do kill Sonic. the culminated effort of Rouge, Shadow, and Silver leads to them quietly killing our hedgehog hero and they do their best to cover it up.

There is an unintended consequence however,

and that comes in the form of,

Tails.

Tails finds out about the murder a year after the funeral. He disappears for quite a long time. Months turn into years, and eventually Tails pops back up with a vengeance. He took his time developing some new technology and digs up Sonic. He wants to use Chaos energy from the emeralds to bring Sonic back from the dead, AND he wants revenge on the ones who killed him.

Lol I soldered one good joint on the SMD, moved onto the second point and completely melted it off of the board

Adventures in soldering

Do not click on the images to make them large. The iPhone 15 Pro Macro mode looks good at pretty much exactly Tumblr image size, and deteriorates rapidly if you look at all the pixels.

Anyway, I tried something weird. For the model railroad streetcar project that I keep talking about, I want to light up the destination display, and that works best if I can find a side-emitting LED that is at most 0.5mm but not very wide. The problem is that side emitting LEDs are rare; most standard electronic LEDs, in particular the tiny SMD ones, emit their light to the top, so I had a bit of a problem…

…until I remembered that any LED is side-emitting if you just put it on its side and solder it in like that. Which was amazingly basically no problem at all (note: Requires at least cheap precision ESD pliers and a binocular microscope and some experience). The LED has size 0402, which means 0.04 inches long and 0.02 inches wide, or in reasonable terms, a millimetre long and half a millimetre wide (and about as tall). There's a picture with the standard cent coin for scale, but all of that is very tiny.

I am happy to report that this worked on the first try, and I managed to not drop any LEDs or resistors, which goes to show: Soldering is a thing you get better at through practice. I certainly used to think I was no good at it just a couple of years ago.

As for the circuit board, I designed this a while ago specifically to challenge myself. I did manage to solder in the 0201 resistors, but I didn't have any 0201 LEDs, and now that I do have them, I have been too scared to use them yet with their weird contacts on the rear instead of sides.

By itself, this is functionally useless, but it means that I will be able to use this technique for the streetcar project. Next time I'll try taking better pictures, though.

Franzis Adventskalender für Arduino - Tag 1

Heute starten wir mit dem ersten Tag des Franzis Adventskalender für Arduino.

Franzis Adventskalender für Arduino - Tag 1 Öffnen wir nun also das erste Türchen. Hinter dem ersten Türchen verbirgt sich ein Arduino Nano V3.

Im Handbuch finden für zum Tag 1, wie man diesen Mikrocontroller einrichtet und die Arduino IDE installiert. Was du noch benötigst, ist ein Micro-USB Datenkabel für die Verbindung zum PC.

Einrichten auf einem Windows-PC

Eigentlich verbindet man den Mikrocontroller nur mit dem PC und dann wird dieser sogleich eingerichtet. Eigentlich! In meinem Fall hat sich der PC mit einem Bluescreen verabschiedet und einer IRQ Meldung, d.h. eigentlich nur das dieser Mikrocontroller einen IRQ belegen wollte, welcher bereits belegt oder reserviert ist. Okay kann passieren, Windows halt, also einmal neu starten und ein zweiter Versuch. Nun hat es funktioniert und der Mikrocontroller wurde im Geräte-Manager erkannt.

Windows Gerätemanager - Arduino Nano von Franzis Da ich bereits mit einigen Mikrocontrollern gearbeitet habe und somit diverse Treiber bereits installiert habe, entfiel der Schritt zum Installieren des seriellen Treibers für den CH340G Chip.

Aufbau des Arduino Nano

Auf dem Markt gibt es diverse Arduino Nano Klone (wie auch dieser hier von Franzis), was allen ziemlich gleich ist, dass diese dasselbe Pinout haben.

Pinout - Arduino Nano V3

Technische Daten des Arduino Nano V3

Den Arduino Nano habe ich bereits in sehr vielen Beiträgen auf diesem Blog verwendet und dir auch im Beitrag Arduino Nano – Übersicht dir diesen bereits vorgestellt. Auf dem Board ist ein ATMEL MEGA328P verbaut.

Hier nun der Vollst��ndigkeit halber die technischen Daten zu diesem Mikrocontroller: Länge45 mmBreite18 mmGewicht7 gFlash Speicher32 KB (von denen 2 KB für den Bootloader reserviert sind)SRAM2 KBEEPROM1 KBCPU Taktgeschwindigkeit16 MHzBetriebsspannung5 VEingangsspannung7 V bis 12 VStromaufnahme19 mAmax. Stromstärke pro I/O Pin40 mAdigitale Eingänge / Ausgänge22digitale PWM Ausgänge6analoge Eingänge / Ausgänge8

Installieren der Arduino IDE 2.0

Im Handbuch wird die Arduino IDE in der Version 2.0.0 Beta-3 dargestellt, mittlerweile haben wir eine offizielle Version zur Verfügung. Diese beiden Versionen sind vom Aufbau her sehr unterschiedlich, daher zeige ich dir in den nächsten Tagen, wie die Schaltungen in der neuen Version programmiert werden.

Arduino IDE 2.0.0 Die aktuelle Version kannst du unter https://www.arduino.cc/en/software herunterladen, die Installation ist denkbar einfach, denn man muss lediglich dem Wizard folgen.

Aufbau der Arduino IDE

Die Arduino IDE hat eine Toolbar, in welcher du die Schaltflächen findest, welche du wohl am meisten benötigst.

v.l.n.r: - Verify, - Upload, - Debug, - ausgew��hlter Mikrocontroller, - Serial Plotter, - Serial Monitor Das Debuggen also das Prüfen von Code während der Ausführung unterstützt nicht jeder Mikrocontroller, auch würde dieses für diese Beiträge viel zu weit gehen.

Programmieren des Arduino Nano

Im ersten Türchen war lediglich der Mikrocontroller, jedoch kann man selbst mit diesem schon einiges machen. Auf dem Board ist zbsp. eine kleine SMD LED verbaut, welche wir zum Blinken, Faden (langsames Auf-/Ableuchten) bringen können.

Auswählen des Mikrocontrollers

Bevor wir einen Code schreiben oder hochladen können, müssen wir den Mikrocontroller auswählen. Dazu navigieren wir über das Hauptmenü von Tools > Board: xyz > Arduino AVR Boards und wählen dort den Eintrag "Arduino Nano" aus. Danach wählen wir noch den Port aus und schon ist die Einrichtung fertig.

Auswählen des Mikrocontrollers Arduino Nano in der Arduino IDE "Hello World!" auf der seriellen Schnittstelle Starten möchte ich jedoch zunächst mit einem kleinen "Hello World!" Beispiel, in welchem wir Text auf der seriellen Schnittstelle ausgeben. Diesen Text können wir uns in der Arduino IDE anzeigen lassen, aber auch andere Tools welche Daten von der seriellen Schnittstelle lesen können wie Putty, MobaXTerm können diese anzeigen. Der Vorteil bei der Arduino IDE ist jedoch, dass wir dafür kein extra Tool benötigen. void setup() { // beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); } void loop() { // ausgeben der Textzeile "Hello World!" // auf der seriellen Schnittstelle Serial.println("Hello World!"); // eine kleine Pause von 500 ms delay(500); } Wenn das kleine Programm hochgeladen wurde, sehen wir in der Konsole folgende Ausgabe. Aus diesem Text können wir entnehmen, wie viel Speicher von unserem Programm belegt wird und wie viel noch frei ist. Der Sketch verwendet 1634 Bytes (5%) des Programmspeicherplatzes. Das Maximum sind 30720 Bytes. Globale Variablen verwenden 200 Bytes (9%) des dynamischen Speichers, 1848 Bytes für lokale Variablen verbleiben. Das Maximum sind 2048 Bytes. Ausgabe der Textzeile "Hello World!" im seriellen Monitor der Arduino IDE.

Blinken der onboard SMD LED Die kleine SMD onboard LED kannst du über den digitalen Pin D13 oder der Konstante LED ansteuern. // onboard LED am digitalen Pin D13 angeschlossen // ansteuern über die Pin Nummer // #define led 13 // int led = 13; // ansteuern über einer Konstanten #define led LED_BUILTIN void setup() { // Definieren das der Pin der LED als // Ausgang dient. pinMode(led, OUTPUT); } void loop() { // Pin der LED auf HIGH setzen digitalWrite(led, HIGH); // eine kleine Pause von 500 ms. delay(500); // Pin der LED auf LOW setzen. digitalWrite(led, LOW); // eine kleine Pause von 500 ms. delay(500); } Wenn wir den Code nun auf den Mikrocontroller übertragen, dann blinkt die kleine, orange SMD LED auf der Platine im Intervall von 500 ms.

How to Choose the Best Through-Hole Resistor Kit for Your Projects

When working with electronics, resistors are an essential component in every circuit. Whether you're an electronics hobbyist or a professional engineer, selecting the right resistor kit can significantly impact the quality and functionality of your designs. While surface-mount resistors are gaining popularity due to their compact size, through-hole resistors continue to be a favored choice, especially for prototyping, DIY projects, and applications that require strong physical connections. Through-hole resistor kits provide the convenience of having a wide range of resistor values available for immediate use.

In this blog post, we'll guide you through the process of selecting the best through-hole resistor kit, introduce you to leading brands like UNI-ROYAL and YAGEO, and provide information on where to purchase these kits from trusted distributors like Unikeyic Electronics. Additionally, we’ll discuss some important FAQs related to through-hole resistor kits.

What Is a Through-Hole Resistor Kit?

A through-hole resistor kit typically contains a variety of resistors with different resistance values. These resistors are designed with leads that are inserted into holes drilled into a printed circuit board (PCB) and soldered in place. This method of assembly makes through-hole resistors more mechanically secure compared to surface-mount devices (SMD), making them ideal for high-reliability applications and scenarios where components may need to be manually replaced.

Through-hole resistor kits are ideal for:

Prototyping and breadboarding

DIY electronics projects

Educational purposes

Projects requiring a strong physical bond between the component and PCB

Key Considerations When Choosing the best through-hole resistor kit

1. Wide Range of Resistance Values

One of the main reasons to invest in a through-hole resistor kit is the flexibility it offers. The best through-hole resistor kits contain a broad range of resistor values, typically from 1 ohm to several megohms, allowing you to handle a variety of electronic applications. Whether you're designing a simple LED circuit or working on a more complex power supply, having a variety of resistor values on hand ensures that you're prepared for any requirement.

A comprehensive kit should include both common E12/E24 values, as well as more precise resistances for high-accuracy designs.

2. Quality and Reliability

When choosing the best through-hole resistor kit, quality is a top priority. High-quality resistors provide accurate and stable resistance values over time, which is critical for maintaining circuit functionality and avoiding failures.

Brands like UNI-ROYAL and YAGEO are well-known for their reliable through-hole resistors. These brands undergo stringent quality control and testing to ensure that their components meet industry standards. By choosing these brands, you are investing in long-term reliability for your projects.

3. Power Rating

Resistors come with different power ratings, which is the amount of power they can dissipate without overheating. The most common power ratings for through-hole resistors are 1/4 watt and 1/2 watt, but you can also find resistors with higher ratings such as 1 watt or 2 watts.

For typical low-power circuits, 1/4 watt resistors are sufficient, but if your project involves higher current or voltage, opt for higher power-rated resistors. The best through-hole resistor kits should offer a range of power ratings to accommodate different circuit needs.

4. Tolerance

Tolerance refers to the precision of the resistor's value compared to its stated value. For example, a resistor with a ±5% tolerance means its actual resistance could vary by 5% from the stated value. Higher precision resistors with a tolerance of ±1% or better are used in applications requiring more accurate performance.

5. Clear Labeling and Easy Storage

A well-organized resistor kit can save you significant time and frustration during your project. The best kits come with clear labeling, usually with each resistor value organized into its own compartment or bag. This allows for easy identification and quick access during the assembly process.

6. Sourcing from Trusted Distributors

Buying from a reputable distributor ensures you are getting genuine, high-quality components. Unikeyic Electronics is a well-known distributor that offers a wide range of through-hole resistor kits from trusted brands like UNI-ROYAL and YAGEO.
