To create a super Wi-Fi signal receiver using copper plates, you'll need to follow a specific antenna design that utilizes copper plates effectively. One popular design is the Yagi-Uda antenna, also known as a Yagi antenna. Here's a step-by-step guide on how to build one:

Materials:
1. 12cm x 12cm sheet of copper, brass, or tinned metal plate.
2. BNC chassis connector.
3. BNC cable connector.
4. 35mm thick PE or styrofoam (can also be thicker).
5. Some 1.5mm2 single core wire.
6. Soldering iron and solder.
7. Drill and drill bits.
8. Screwdriver.
9. Wire cutter.
10. Ruler or measuring tape.
11. Electrical tape.
12. A Wi-Fi antenna to connect to the receiver.

Steps:

1. **Prepare the Plate**: Cut the 12cm x 12cm sheet of copper, brass, or tinned metal plate to the appropriate size if necessary.

2. **Mark and Drill Holes**: Measure the center of the plate by drawing lines from the corners and making a mark 20mm from the center. This is where you will attach the BNC chassis connector. Drill a hole at the marked point, ensuring it's the correct size for your BNC chassis connector.

3. **Attach the BNC Chassis Connector**: Insert the BNC chassis connector into the hole and secure it in place using small bolts.

4. **Create the Reflector Element**: Cut a 10cm length of the single core wire and bend it into a V shape with 7cm sides and a 6cm gap in the middle. Attach the reflector element to the copper plate, positioning it parallel to the long side of the plate and about 1cm from the edge. Secure it with electrical tape.

5. **Create the Driven Element**: Cut two 10cm lengths of single core wire and attach them to the BNC chassis connector, ensuring they are parallel to the reflector element and spaced 1.5cm apart.

6. **Create the Director Elements**: Cut four 9cm lengths of single core wire and attach them to the copper plate, positioning them parallel to the reflector element and spaced 2cm apart.

7. **Connect the Wi-Fi Antenna**: Attach the BNC cable connector to the driven element and connect the other end to your Wi-Fi antenna.

8. **Mount the Antenna**: Mount the antenna on a mast or stand, ensuring that the reflector element faces the direction of the Wi-Fi signal source.

9. **Test the Signal**: Use a Wi-Fi signal strength meter or a device such as a laptop or smartphone to test the signal strength of your new super Wi-Fi signal receiver. Adjust the antenna's position and direction as needed to maximize the signal strength.

Keep in mind that this design is based on a Yagi-Uda antenna, and the dimensions provided may need to be adjusted depending on the specific frequency of your Wi-Fi signal

An older, white haired man walked into a jewelry store one Friday evening with a beautiful young girl at his side. He told the jeweler he was looking for a special ring for his girlfriend.

The jeweler looked through his stock and brought out a $5,000 ring and showed it to him.

The old man said, "I don't think you understand, I want something very special." At that statement, the jeweler went to his special stock and brought another ring over. "Here's a stunning ring at only $40,000," the jeweler said. The young lady's eyes sparkled and her whole body trembled with excitement.

The old man seeing this said, "We'll take it." The jeweler asked how payment would be made and the old man stated by check. "I know you need to make sure the check is good, so I'll write it now and you can call the bank on Monday to verify the funds and I'll pick the ring up Monday afternoon," he said.

Monday morning, a very teed-off jeweler phoned the old man. "There's no money in that account." "I know", said the old man, "but can you imagine the weekend I had?"
