LC 360 HEAD SENSORS

This article was originally posted on the Tactical Action Game post board.   Michael Goldberg was nice enough to allow us to post the article on here and preserve the information in our archives.

. This should help as it applies to all LC vests into which you can plug a back sensor.

From Michael:  I just finished making my own mod to these instructions to support Radar Extreme. Assuming that you have purchased the diodes at DigiKey, here's what I did to make my sensors (I've finished 8 so far):

Parts List (per 360 head sensor)
2 Photo IC Infrared 38.0 kHz W/HL DigiKey #PNA4612M00YB-ND
2 Toy Sheriff's badges (used to mount diodes)
2 2-inch safety pins (used to pin sensors to cap or bandana)

[Option 1]
1 6 foot modular handset cord (connects between telephone base and handset on fully modular telephones - that has the RJ-22 jack that fits into the RadarExtreme Auxiliary port).
1 Quick-Connect Modular Jack/Cord set (Radio Shack #279-251) (Comes with 25 feet of 4 wire RJ-14 thin line cord - I'm using 16 inches per 360 sensor so this will make a lot of sensors)
1 Quick-Connect Modular Jack (Radio Shack #292-252)
[end Option 1]

[Option 2 - Cheaper]
1 3 foot section of 4-connector wire
2 9" sections of 4-connector wire
1 RJ-22 modular handset plug
1 3 foot section 1/4" flexible plastic conduit
[end Option 2]

Tools Needed:
1) Soldering Iron
2) Hot Glue Gun
3) pen knife
4) wire stripper

Instructions:

[Option 1]
1) Cut a 16" length of RJ-14 cord
2) Prepare the cord on each end as follows:
a) With a pen knife, separate wires 1" down
b) Strip about 1/2" of insulation off wires
c) Cut the 3rd of 4 wires off so it doesn't get in the way (Only need to connect 3 wires - 1st wire has black stripe on insulation, cut the 3rd wire so you only have wires 1,2 and 4 exposed)

3) For each of the 2 diodes, do the following:
a) remove the diode from the housing (just peels off)
b) turn the diode over so the sensor faces down
c) with the diode held in your left hand and the leads pointing to the right, mark how the connections will be made and solder:
i) wire 1 (black strip) to lead 2 (middle of the three leads)
ii) wire 2 to lead 1 (top of the three leads)
iii) wire 4 to lead 3 (bottom of the three leads)

4) With the black stripe of the cord on top and the opening of the quick connect modular jack pointing downward, press the cord into the jack and insert into cover. This will add an RJ-14 jack to the middle of the cord to which the front and rear sensors have just been attached.

[End Option 1]

[Option 2]
1) Prepare the ends of the two 9" lengths and the 3-foot length of 4-conductor wire as follows:
a) With a pen knife, separate wires 1" down
b) Strip about 1/2" of insulation off wires
c) Cut the 3rd of 4 wires off so it doesn't get in the way (Only need to connect 3 wires - 1st wire has black stripe on insulation, cut the 3rd wire so you only have wires 1,2 and 4 exposed)

2) Create the wiring harness by soldering the 3 cables together, matching the wires to their corresponding color: black wire to black wires, white wires to white wires, green to green, red to red (or whatever colors you have.)
2a) Cover three foot section with flexible conduit

3) For each of the 2 diodes, do the following:
a) remove the diode from the housing (just peels off)
b) turn the diode over so the sensor faces down
c) with the diode held in your left hand and the leads pointing to the right, mark how the connections will be made and solder (to the each of the 9" sections of the wire harness created in step 2):
i) wire 1 (black strip) to lead 2 (middle of the three leads)
ii) wire 2 to lead 1 (top of the three leads)
iii) wire 4 to lead 3 (bottom of the three leads)

4) Use a crimping tool to attach the RJ22 jack to the remaining leads of the wire harness (bottom of the 3 foot section).

[End Option 2]

5) In the center of each Sheriff's badge, drill an 11/64" hole.
6) Slip a safety pin all the way into the clip on the back of the badge. (The Sheriff badges I bought have a clip on the back for attaching to a pocket.)
7) Mount the diodes on the badge from the back - the diode itself will fit into the hole. I drilled from the front, slipped the diode from behind under the clip, and the clip holds it in place. If the clip breaks, insert the safety pin first, then the sensor, then epoxy the clip back together to hold everything in place

This is the 360 head sensor. Use handset cord or wire harness to attach to vest. Sensors attach to cap or bandanna via safety pins. Alternatively, use popsicle craft sticks, hot glue badges on opposite sides of craft stick so looks like a funky lollipop, insert base into bandana so one sensor faces front and other sensor faces back.
