Embedded LED 3D Printed Christmas Tree
This is a 3D-printed Christmas tree with embedded addressable LEDs inside. So it is possible to program the LEDs for nice light effects and using the 3D printed structure as a diffusor.
The tree is separated in 4 stages and a base element (the tree trunk) to make it easier to assemble and embed the LEDs during the prints. So in total 5 elements have to be printed.

π Inductors: The Masters of Magnetic Energy
Inductors are key components in electronics that store energy in the form of a magnetic field. They resist sudden changes in current, making them indispensable for filtering, energy storage, and signal processing in circuits.

Inductors are key components in electronics that store energy in the form of a magnetic field. They resist sudden changes in current, making them indispensable for filtering, energy storage, and signal processing in circuits.
How Inductors Work
An inductor is essentially a coil of wire that generates a magnetic field when current flows through it. This magnetic field opposes changes in current, a phenomenon governed by Faraday's Law of Electromagnetic Induction. The inductance, measured in henries (H), depends on the number of turns in the coil, core material, and coil geometry.
Types of Inductors
1. Air-Core Inductors:
- No magnetic core.
- Used in high-frequency applications like antennas and RF circuits.
2. Iron-Core Inductors:
- Higher inductance values.
- Common in power supplies and transformers.
3. Ferrite-Core Inductors:
- Compact, high-frequency capability.
- Ideal for filtering and EMI suppression.
4. Toroidal Inductors:
- Donut-shaped.
- Efficient and low electromagnetic interference.
Applications in Robotics
- Power Supply Filtering: Smoothens out voltage ripples in DC-DC converters.
- Motor Control: Manages current in motors, reducing noise and improving efficiency.
- Signal Processing: Filters signals in audio and RF circuits.
- Transformers: Used for voltage step-up or step-down in power systems.
Key Facts About Inductors
- Energy Storage: Inductors store energy in their magnetic fields, releasing it when needed.
- Reactance: The opposition to AC current increases with frequency, making inductors useful for filtering high frequencies.
- Inductive Kickback: Rapid current changes can produce high voltage spikes, often mitigated by diodes or snubber circuits.
Quick Tips for Using Inductors
- Choose an inductor with a current rating higher than your circuitβs requirements to avoid overheating.
- For high-frequency applications, opt for ferrite-core or air-core inductors.
- Use shielding to minimize electromagnetic interference in sensitive circuits.

Things you didn't know about Arduino!
βοΈArduino Uno is a controller based on the ATmega28 microcontroller, the platform consists of 14 inputs/outputs (6 of which are via PWM), 6 analog inputs, a 16MHz crystal oscillator, a USB port, a fast port, an ICSP port, and a reset button.
The word "Uno" means one in Italian. It's no coincidence that the creators of Arduino Uno tried to start a new era and a new flagship in the Arduino family of controllers with this new controller, and they succeeded. The reason is that Arduino Uno is much more compact, convenient, fast, simple, and of course cheaper than its other "brothers" in the Arduino family of controllers.
Briefly about Arduino Uno:
Microcontroller ATmega328
Operating voltage 5 V
Input voltage (recommended) 7-12 V
Input voltage (maximum) 6-20 V
Digital input/output 14 (6 of which are possible by KIM (Pulse Width Modulation)
Analog input 6
Current constant through input/output 40 mA
Current constant up to 50 mA for 3.3 Vk
Flash memory 32 KB (ATmega328) of which 0.5 KB is taken as a bootloader.
RAM 2 KB (ATmega328)
EEPROM 1 KB (ATmega328)
Frequency 16 MHz
In addition, the Arduino Uno device can be purchased from a USB or an organization source connected to it. In this case, if there are several sources, one of them is automatically selected.
The Arduino Uno controller is based on the ATmega328 microcontroller. This microcontroller has 32 kB of flash memory, of which 0.5 kB is reserved for the bootloader, in addition, 2 kB of RAM and 1 kB of EEPROM. Each of the 14 digital outputs can be configured as either input or output. This is done using the pinMode(), digitalWrite() and digitalRead() functions. Each output can drive a resistance of 20-50 kOhm and a current of up to 40 mA.
