Freeformable Circuit | Real Freeform Circuit!

Things used in this project

Hardware components

Arduino Nano R3

LED (generic)

TSOP1738 IR receiver

Software apps and online services

Arduino IDE

Hand tools and fabrication machines

Soldering iron (generic)

Story

I have been inspired by the freeform circuit...

So I just made a freeform circuit that is even freeformable (can be formed into any shape and design).

This circuit is a 18 LED chaser in which patterns are changeable with IR remote. Each LED can be controlled separately.

Things You Need

1. A copper or brass rod of 0.5 - 1 mm diameter

2. Thin copper wires. I got it from motor windings.

Starighten the rod

Copper wires

Forming Into Shape

As I designed for a hexagonal frame I shaped it using pliers and used graph for reference.

Hexagonal Frame

Arduino Preparation

Remove the Arduino pins and braces with cutter and pliers. Desolder pins from the Arduino Nano don't break it!

Braces removed Arduino

Joining All

I soldered a four copper rods on the screw hole of arduino with the USB port GND to the hexagonal frame.

soldered frame

Also I soldered LEDs with the wires and used 330ohms resistor for each LED.

Led arms

Finally each LED wire is soldered with frames.

(LED -ve to the frame)

IR Receiver Part

The TSOP1738 IR receiver is mounted on top of Arduino Nano's ISP head And output pin to the Arduino Rx pin.

TSOP1738 pin bending for mounting

soldering TSOP from backside

Finally!

I have messed on soldering part on the frame since copper doesn't allows the soldering to bind together. I suggest to use Brass rods for better results.

Don't use thick soldering leads! it will surely get in trouble...
