| | My grand son appreciates driving a remote regulated (RC) vehicle, and also we intended to include First Person View (FPV) video clip to it.
After looking into numerous possible video methods, I decided to utilize a small cam that would not look as well huge for the vehicle, as well as have it connect as if the video feed could be seen on a TELEVISION, or goggles, or a mobile DVD player.
Step 1: PARTS
RC TRUCK
If you do not have an RC vehicle, get one that has a deck behind the taxi, huge enough to hold a 4-cell AA battery owner. Low-cost trucks might be purchased for around $30 to $40.
PARTS FOR FPV
At the time of writing this instructable, the electronic camera, transmitter as well as receiver I picked were each valued at $19.99 in United States funds at or $26.65 in Canadian funds at the Canadian place. There are more affordable systems offered on Amazon, yet they are delivered from China, and also I assumed that units from a trustworthy North American company would certainly make certain to be trusted although they are additionally made in China.
1. Camera: "700TVL Camera Module for 250 Quadcopter" runs on 12v.
2. Transmitter: "8 Channel 200mW 5.8 GHz Wireless Audio/Video Transmitter for FPV" has a built-in microphone and also transfers the sound with the video clip. Works on 12v.
3. Receiver: "Helistar 5.8 G FPV Wireless Receiver" works on 6.5 to 15v.
4. 2 - 4-cell AA battery holders with an integrated button. Two owners fit far better in the truck than one 8-cell holder. The truck makes use of 6 AA batteries and also I thought about taking advantage of them as well as adding two more, in series, for the cam and also transmitter, but I believed it would be easier and far better to have a separate collection of batteries.
5. 1 - 6-cell AA battery owner with a button, either built-in or different. I couldn't discover one with a built-in switch. This is for the receiver.
6. 1 - male-male, 3-wire RCA cable television, to connect a TV to the wire supplied with the receiver. If sound isn't crucial to you, a single-wire RCA cable will certainly do the video. A various wire might be required for goggles or a portable DVD player, having RCA links at one end for the receiver cable, as well as a 1/8 inch (3 mm) audio/video plug at the other (or a cord with audio/video plugs at both ends to go from the receiver directly).
PARTS FOR BRACKET FOR CAMERA
A. 1 - Plastic lozenge box to make the video camera owner
B. 1 - Dental floss box to make the bracket to hold the video camera holder on the vehicle
C. 4 - half-inch lengthy #2 round head bolts, lock-washers as well as nuts for the electronic camera
E. 2 - quarter-inch lengthy # 4 round head screws, lock-washers as well as nuts for the brace
F. 2 - three-eighth-inch lengthy # 6 round head screws to attach the bracket to the vehicle
G. 1 - Sprayer from a container of a cleansing product, whose tube has the proper inside size for a # 2 screw to slide within. Some sprayers have tubes that are also small or as well large.
H. Electrical tape
DEVICES
1. Blowpipe and also solder
2. Needle-nose pliers
3. Screwdrivers to fit the bolts and screws
4. Drill and also drill bits
5. Hacksaw
7. Energy blade
8. Tinsnips or scissors
9. Submit
Action 2: Make the Holder as well as Bracket for the Camera
1. Cut the lozenge box to ensure that the cam fits inside. File the sides smooth. This is the cam owner.
2. Cut the dental floss box to hold the owner. File the edges smooth. This is the bracket.
3. Step and pierce openings in the cam owner to match the placing openings in the cam circuit card.
4. Cut 4 items of the sprayer tube, each piece 1/4 inches long. These will be the stand-offs to hold the video camera motherboard far from the owner.
5. Affix the camera to the owner with the # 2 bolts, sprayer tube pieces, lock-washers and nuts.
Step 3: Attach the Bracket to the Truck
1. Cover the brace with electric tape to make it black instead of white.
2. Pierce two openings in all-time low of the brace to ensure that the # 6 screws slide in conveniently.
3. Area this on the top of the vehicle taxi, and mark where the holes sit.
4. Pierce pilot openings there for the screws.
5. Affix the bracket to the truck.
6. Use the # 4 screws, lock-washers and also nuts to attach the electronic camera owner to the brace.
Step 4: Attach the Battery Holders to the Truck
1. Location 8 batteries in the two 4-cell battery owners after making sure the activate the battery owners are off.
2. The deck behind the taxi of our truck was a little also brief for the battery owners. I needed to remove the bumper at the back, using the hacksaw as well as tinsnips, to fit one battery owner underneath the deck. The cables need to lie towards the back of the vehicle.
3. The cords from the cam can be on top of the deck, running in the direction of the rear of the vehicle, with the 2nd battery owner sitting on top of them.
4. An elastic holds the two battery holders in place.
Step 5: Place the Transmitter
The transmitter sits on top of the top battery holder, held by an additional elastic. The black and red power cords from the battery owners and also the transmitter lie to one side. fpv head tracking system from the video camera as well as the five-wire bundle from the transmitter need to lie under the upper battery owner, running in the direction of the rear of the vehicle. The elastics make it simple to lift the upper battery owner and move the cables under it.
Some of the wires have connectors, however I cut them off as well as soldered the appropriate wires together. Electrical tape goes around each link.
1. The black wire from one 4-cell battery owner goes to the red wire of the other battery owner, in order to link the batteries in collection to produce 12 volts. The remaining black cable from the battery owners mosts likely to the black cable of the transmitter power cords. The remaining red cord from the battery holders mosts likely to the red cable of the transmitter power wires.
2. The cords from the electronic camera and the five-wire package from the transmitter ought to be standing out the rear of the truck. The electronic camera has 3 cables: yellow, red and black. The transmitter has 5 cables in its result group: yellow, red, black, white and also eco-friendly. The white and also eco-friendly cords are audio outcome and do not attach to anything. The other like-colored wires go together: yellow to yellow, red to red, as well as black to black.
3. After soldering the cords and also wrapping electrical tape around the solder joints, you can tuck the cables in the elastic under the lower battery holder.
The switch on the battery holder that is under the deck ought to be activated and kept on. The power will be managed by the turn on the top battery holder.
Action 6: Connect the Receiver
1. Location 6 AA batteries in the 6-cell battery owner.
2. Put the receiver in addition to the battery holder as well as protect it with an elastic.
3. If the battery holder has a button, solder the matching cords of the battery owner and also receiver, red to red and black to black. If there is no button, one can be wired in, in between the two red wires.
4. Wrap electrical tape around the solder joints.
5. Tuck the wires under the flexible.
Step 7: Enjoy Using It
1. Make use of a male-male, 3-wire RCA cable television to link the receiver result cable television to a TV. If sound isn't essential to you, a single RCA wire will certainly do the video. A various cable television may be needed for safety glasses or a portable DVD gamer, as explained in the "Parts for FPV" area above.
2. Turn on the receiver power and the truck power.
3. The video clip feed should be visible on the TV.
When the receiver is outdoors with a lengthy cable to the TV within, and also a clear line of vision from the transmitter, the variety is outstanding. I took the vehicle down the street while speaking on a cellular phone with my better half as she watched the TELEVISION, and also the video clip and sound were still very clear at 150 meters or 165 lawns. I didn't go any kind of further.
However when the receiver is inside your house and the vehicle is driving outside, the brick and also cinder block wall surfaces of our house and garage degrade the signal, and also the array is just around 50 meters or 55 lawns. | | | |
