De Werkbank
Welcome to The Workshop
De Werkbank is de kennisplek van Sinuss — eerlijke, praktische uitleg over componenten, schakelingen en de keuzes die makers dagelijks maken.
Choosing connectors: temporary, secure or neatly detachable
A connector only becomes visible when it fails. Connection drops, project stops, cause unclear. While the problem was there from the start: the wro...
Connecting sensors: voltage, signal and communication
Sensors look simple: plus, minus, signal. But there are four things that regularly go wrong, and none of them have anything to do with the sensor i...
Arduino, Raspberry Pi and ESP32: what's the difference?
Three platforms, three names that constantly appear together in tutorials and forum posts. But they're not variants of the same thing. They're fund...
Using a breadboard: useful, but not for everything
A breadboard is the fastest way to test an idea without soldering. No iron, no solder, no permanent decisions. Push a component in, connect it up, ...
Pull-up and pull-down resistors: small parts, big difference
You write the code, everything compiles, the button should do something — but nothing happens. Or worse: the button triggers on its own without bei...
MOSFET or transistor: which do you choose for switching?
Your microcontroller pin delivers signals, not power. An LED on a pin is just about acceptable if you keep the current low. A motor, a relay or an ...
Connecting LEDs without burning them out
Connecting an LED looks simple. Two wires, apply voltage, light appears. Until it doesn't work, or worse: it burns out immediately.
The problem is ...
Choosing resistors: value, power rating and tolerance
A resistor is the cheapest component on your workbench. And yet a surprising number of things go wrong the moment you stop thinking carefully about...
Using a multimeter for electronics: measure, don't guess
Guessing what's wrong costs time. Measuring takes seconds. A multimeter is the tool that makes the difference between an hour of searching and know...
Power supplies for small electronics projects
An ESP32 that randomly resets. A sensor giving strange readings. Wi-Fi dropping out. In many cases the code is fine — the power supply is the probl...
Edge AI on your Raspberry Pi: what can the Coral USB Accelerator do?
Machine learning on a Raspberry Pi — it sounds like something that would only become feasible in a few years. But that moment is already here. Goog...
