Add for your Robot- IR jammer

I saw this from the great creat from RadioShack and wanted to share it with you guys. Sow how could you use this in a robot? or what use could it have? If you are using a sumo robot well this could be a good idea for not beaing detected. or dont want anyone to change the TV just point it at the tv an the controller wont work sow you can watch you TV shows as long as you want. All of the parts can be bought at RADIOSHACK. I include the item number.

  3. Four "AA" batteries
  4. wire cutters
  5. Power drill with 7/64 and 13 /64 bits
1.Solder the Op Amp to the circuit board, near the 
tp edge, with three empty rows available for the LEDs. 
Solder only the 1, 2, 3, 4 and 8 pins. Pin 1 is indicated 
by a circle on the Op Amp.

2.Make a solder path from Pin 4 to the bottom of the 
circuit board and along the bottom edge. This will 
form the Ground.

3.Make a solder path from Pin 2 that goes down two 
rows. This will be bridged by a resistor in the next step.

4.Solder a 10K resistor (R13) just below the Op Amp 
with the leads aligned with Pin 1 and Pin 3. The resistor 
should bridge over the solder path from Pin 2.

5.Make solder paths that connect R13 to Pin 1 and 
Pin 3.

6.Extend the solder path from Pin 3 approximately 
three more rows and solder a 10K resistor (R12) so that 
it bridges the path from Pin 4. Make a solder path that 
connects R12 to Pin 8 of the Op Amp.

7.Solder a 10K resistor (R5) connecting the end of 
the solder path from Pin 3 to the Ground.

8.Solder a 1K resistor (R3) downward from the solder 
path from Pin 2.

9.Solder a 4.7K resistor (R11) left from the solder 
path from Pin 1.

10.Solder a 10K resistor (R10) left from the R3. 
Align the ends of R10 and R11, and solder a path to 
connect them.

11.Solder a .001uF capacitor (C3) to R3. Make a solder 
path to connect C3 to the Ground.

12.Solder a .1 uF capacitor (C2) to the right of the 
Ground. Solder C2 to R12.

13.Solder a .1 uF capacitor (C1) to the left from Pin 1.

14.Solder a 10K resistor (R9) down from the open 
lead of C1. Make a solder path to the Ground.

15.Solder a 10K resistor (R8) up from the open lead of 
C1. Make a solder path to Pin 8 of the Op Amp.

16.The transistor has three leads: Collector, Base and 
Emitter. Insert the transistor into the circuit board with 
the ?at side facing the Op Amp. This places the Collector 
toward the top edge of the circuit board and the Emitter 
toward the bottom edge.

17.Solder the transistor’s Base (center lead) to C1.

18.Make solder paths to connect the transistor’s Emitter 
to the Ground below R9.

19.Insert a 10 ohm resistor (R7) along the top edge of 
the circuit board, aligning one end with the transistor. 
Solder the resistor in place and make a solder path 
connecting it to the transistor’s Collector.

20.Bend and solder the two IR LEDs (D1 and D2) to the 
circuit board so that they face outward from the board, 
side-by-side. Leave the leads long enough to extend 
from the board. The ?at sides (and shorter leads) of D1 
and D2 must be on the side closest to R7.

21.Make a solder path from left lead of D1 to R7; make 
a solder path from the right lead of D1 to the left lead of 
D2; make a solder path from the right lead of D2 to the 
solder path from Pin 8 of the Op Amp.

22.Drill a 7/64-inch hole in one end of the project box. 
Insert the red and black battery holder wires into the 
hole. Solder the red wire to C2 away from the Ground, 
and solder the black wire to the Ground.

23.Place the IR Jammer into the project box with the 
LEDs facing opposite the hole for the battery holder 
wires to identify where to drill openings for the LEDs.

24.Drill two 13/64-inch holes in the project box, insert 
the IR jammer into the box, aligning the LEDs with the 
two holes, and seal the box.

25.Install 4 “AAA” batteries, ?ip the battery holder 
switch to “on” and point the IR LEDs in line of sight to 
any IR sensor.
