TV antenna

antenna jack: A coax connector was added to this weather radio. Now an external antenna can be connected to improve reception. The connector is mounted on the side of the radio near the base of the telescoping antenna. Got the F connector by taking apart a tv signal splitter. The mounting bracket is cut from a piece of aluminum angle. Holes were drilled for the F connector, two small bolts and the wire that used to go to the rod antenna. I plan to run coax to a homemade 3 element yagi antenna that will be in my attic. For now, I can connect up to the coax coming from an outdoor tv antenna.

Improvised remote controll

Remote control cars are extremely entertaining and are one of the most popular toys in the world. Many enthusiasts build their own remote control cars so they can customize the engine, steering capabilities and other features. Building a remote control car at home can be challenging but also very rewarding. This article provides detailed instructions on how to build your own remote control

Building the Remote Control Device

• 1. Glue two pairs of resistors to the inside wall of the housing of the handheld remote control device using the rubber cement. Leave a space of approximately 1 inch between the two pairs of resistors.
• 2. Drill a small hole through the wall of the housing in the middle of the 1-inch space, then place the 4-inch steel rod through the hole.
• 3. Snap the rotating steel head with the electrode to the end of the bar that is inside the remote control housing. Snap the plastic knob from the remote control kit to the end of the steel rod outside of the housing. This is the device that will steer the car.
• 4. Strip some wire coating from the end of the trigger wire and crimp the ends of the wire around one pair of resistors.
• 5. Close the remote control housing by snapping the two halves together and screw the antenna onto the top of the remote control device. Your homemade remote control car is now ready for use.

things you need:

• Remote control car kit
• Rectangular steel plate 1 foot long by 6 inches wide
• 4 steel clamps
• 4 steel screws
• Phillips-head screwdriver
• Powdered graphite
• 4 washers
• Adjustable wrench
• 4 steel bolts
• 2-way radio frequency electrical motor
• Wire strippers
• 4 resistors
• Rubber cement
• Electrical drill
• 4-inch steel rod
• Rotating steel head with electrode that is 1 inch in diameter

Wi-Fi antenna

A Wi-Fi antenna with a high range can be used to capture the signal from areas with free internet. You too can make an antenna and browse the internet for free.


Instructions

1. There are many Wi-Fi networks from where you can get temporary signal. Almost any library, bookstore, coffee shop and airport has a Wi-Fi network.
2. The antenna will capture the signal by its position and structure. You will need a large shiny bowl or wire bowl.
3. You will also need a Wi-Fi antenna adapter. This will have a USB connection. Connect it to your computer. Your laptop doesn’t have the required power to capture the Wi-Fi signal. Position the adapter in the center of the bowl. The position the antenna facing an area with signal.
4. An antenna like this can increase the signal power by 45%. But this is a short-term solution. If you want something more durable, then talk to your local internet provider.
