With this participation tree, drag racing Testament alter to and adept.
Familiarity trees are those descending lights you glare at automobile races that apprise drivers to begin their engines, prepare to chase and then haul off. Building your own knowledge tree can be done using some commonly initiate materials from your limited hardware store. For these directions, we Testament advantage 12-volt lights and wiring To admit you to advantage a machine battery to dynamism the lights, permitting you to bring this tree outside with you to the relay track to grasp acknowledged style drag races.
Instructions
1. Intersect your plywood folio in half lengthwise, leaving you with a 2-foot by 4 foot panel. Followed by "Stage," then the three sets of amber lights and finally the green lights. When the green lights are illuminated the drivers should begin the race. At any point in time if you turn on the red lights, the drivers should turn off their engines.
Site one 2-foot-wide borderline of the board as top and the other as backside.
3. Drill and mount one caucasian luminous and socket in the centre of Everyone of the two boxes at the top of the board and classify these two top boxes as "Pre-Stage" with your marker. When these lights are illuminated, drivers Testament discriminate to begin their engines.
4. Drill and mount one immaculate burnished and socket in the centre of both of the two boxes even-handed under the two boxes drilled and decided in Method 3, tab these two boxes as "Sheet." When drivers observe these lights adorn they will know the race is about to start.
5. Drill and mount one amber light and socket in the center of each of the six boxes below the four white lights installed in Step 4. These three sets of amber lights will be lit, counting down toward the green lights which will indicate the race has begun.
6. Drill and mount one green light and socket in either box below the last amber lights. When these lights are illuminated, the race begins.
7. Drill and mount one red light and socket in the center of either box below the two green lights.
8. Wire the back of the board. Staple a length of wire, 20 feet long along the left side of the back of the board with one end of the wire at the top and the other extending below the bottom of the board, label this wire as "Positive." Staple another length of wire, 20 feet long along the right side of the back of the board, and label this as "Negative."
9. Install a 12-volt light switch beside the positive wire on the back of the board, one for each two side-by-side boxes of lights. There should be seven light switches installed on the back of the board.
10. Wire together the lights in series. Connect one length of electrical wiring from the positive wire to the light switch, one from the switch to the bulb, one from the bulb to the other bulb beside it and finally, from the bulb to the negative wire. Repeat this step for all seven rows of lights. You will need to strip a small amount of shielding from the positive and negative wires to facilitate a good electrical connection for each set of lights.
11. Connect the loose end of the positive wire to the positive terminal on the car battery and the loose end of the negative wire to the negative terminal on the battery. When you are ready to begin your race, standing between the two cars, flip the top switch to turn on the "Pre-Stage" lights. Discard or establish aside one half of the plywood period, as by oneself one half-sheet is required for this use.2. Allure a path down the Centre of your board lengthwise, then allure on seven lines, every 12 inches from side to side, perpendicular to the deep line of the board. You should immediately accept your board divided into 16 12-inch by 12-inch squares.
