Recently, another member joined my family. The dog Dafne.
Very agitated (feature race), she likes to be always on our side, participating in our daily lives.
After receiving all the vaccines, the veterinarian has authorized the rides with her. The color does not help much to be visible in the night rides. Hence, the inspiration for the collar.
Step 1: Materials
- Duct Tape
- Pouch with Velcro to accommodate the battery + inverter
Step 2: Cutting the wire and putting on a leash
The wire comes with 3 meters. I measured how much I would need, from the collar, and cut as needed.
Note that I used the party that has a connector for connecting to the inverter (which has an internal circuit with an oscillator based on the integrated circuit 555, operating in a range of 6 to 18 volts).
After that I went through the wire by the collar and securing with adhesive tape to cover the collar. The wire that feeds the neon out of the inverter (black box) was placed on the handle with electrical tape. The battery (9v) + inverter stayed in the bag and secured with velcro strap on the collar. Button on / off switch is inside also may suffer more modificacões.
Step 3: Operation of the Elwire
The neon is essentially a flexible copper wire (thicker) impregnated phosphor, covered by an insulating transparent and another thinner wire around (spiral along the thicker wire), also covered by another layer of transparent insulator. The color of the thread, this one depends solely because the colored transparent layer of phosphor, when excited is white.
Works as follows: an alternating voltage is induced around a 150 V at a frequency of 400 to 4000 Hz (Function Drive). That causes the wires to form a capacitance which excites the phosphor and generates luminescence. It is as if the wire were several capacitors connected to each other.
A good tutorial on how to weld is here at Instructables:
Step 4: End
The intention was to use the material I have ever had in my hands. The Neon was fixed with duct tape, because the material will be reused.
I hope you enjoy.
