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.
1. A copper or brass rod of 0.5 - 1 mm diameter
2. Thin copper wires. I got it from motor windings.
As I designed for a hexagonal frame I shaped it using pliers and used graph for reference.
Remove the Arduino pins and braces with cutter and pliers. Desolder pins from the Arduino Nano don't break it!
I soldered a four copper rods on the screw hole of arduino with the USB port GND to the hexagonal frame.
Also I soldered LEDs with the wires and used 330ohms resistor for each LED.
Finally each LED wire is soldered with frames.
(LED -ve to the frame)
The TSOP1738 IR receiver is mounted on top of Arduino Nano's ISP head And output pin to the Arduino Rx pin.
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...
