New screw top jars were purchased from a craft store to become clear enclosures for laser tag receivers. A 5/32" hole was drilled in the center of the cap to fit a #8 bolt. Other components were gathered. The previous model used a high intensity red LED to indicate hits but in this version it has been replaced with a NeoPixel so any color can be used to indicate team color and color-coded hits.

3@ TSOP4856

1 @ Steel #8 nut
1@ 10uF capacitor with radial leads
1 @ 100Ohm resistor
1@ 1" Nylon bolt with thumb screw knob
1 @ Screw top jar
1 @ RJ11 telephone cord with jack with at least 3" of wire
Components to make 1 receiver
The three brass nuts were put on a long #8 bolt and solder was applied to three sides of each hex nut. A TSOP4856 was soldered to the spaced-out brass nuts which had a gap between each. The loads of the
Another hole was drilled in the jar lid large enough to fit the telephone cord. Once inserted through the hole the phone cord sheath was stripped away 1/2" (12mm) and the tips of the wire were stripped 1/8" (5mm) and tinned.
The 10uF capacitor was soldered between the Vcc and GND terminals of the TSOP4856 leads. This capacitor was to filter power which may pick up interference between the sensor and the controls model. The capacitor was polarity sensitive so care was taken to attach the negative terminal to the center pin of the TSOP4856.
The 100 Ohm resistor was soldered to the end of the yellow phone wire and the other end was soldered to the Vcc terminal of the TSOP4856 array. The red phone wire was soldered to the signal wire of the TSOP4856 array. The black wire was soldered to the IN terminal of the NeoPixel. The positive and negative terminals of the NeoPixel were soldered to the Vcc and GND terminals of the TSOP4856 array.
The TSOP4856 leads were bent in order to make them sit closer to the brass nuts and reduce the overall diameter. This was necessary to fit everything inside the clear jar. The nylon bolt was inserted through the jar lid and a steel nut was threaded on but not tightened. The array of components was eased onto he bolt which was spun to move the array down. Once the bolts were threaded into all three nuts the steel washer was sighted to the base of the lid with pliers.
Hot glue was applied to the entry point of the phone cord. The jar was screwed onto the lid to complete the receiver.
