Cheap Hop Unit Tracer

[WhatsMyName]

 

There are videos on it online so I'll keep it short.

 

You'll need:

3x leds (3mm water clear ultra bright blue)

3x 100Ohm resistors-optional

Cable and connectors

Old/cheap hop unit

Tracer bb's

Heat shrink

Some basic tools

 

How to:

Fit Your hop unit to decide on how to use available space. I fitted mine on the opposite to side of where bolt plate is.

Drill 3mm holes in space between hop chamber and feeding tube neck-this is very cruicial for Your gun to work.

Now test fit leds if they are flat headed just test drop a single bb down the feeding tube and glue leds in. I clipped my diodes, buffed them with a dremel and glued them in.

Solder them together in parallel(+to+,-to-),optionally put 100ohm resistor in front of each one. Wire to power source- I used £1 torch guts (3x1.2v AAA in a battery box running at 2.8V, leds operate at about 3V so I skipped the resistor part.

 

Alternative way of powering:

Wire leds in line(+to-,+to-...), solder 150ohm in front and plug to Your gun battery(if You run more that 9.6V as this will burn up over 9.9V.

 

Pros:

+Cheap (I spent £15)

+Doesnt affect gun's operation

+See where Your bb's are going at night

+Looks cool

+Use to lure and distract enemy

Cons:

-Enemy can trace You back 

-If always on can be spotted if directly looked at (hint of blue down the barrel)

-Need to buy tracer bb's

 

Things to consider:

I used plastic SHS hop- it glows when leds are on and lets light "escape"

Pressure switch or wiring it to trigger/mosfet would make it less of a Tactical Traitor and more of a Tactical Tracer as it would be on only when needed.

 

Appologies to all for whom this tutorial is not sufficient enough-my phone died when posting first time and I just couldn't be bothered to write an exhausing essay on dropping current, resistance, soldering and all that...

Use UV led and one is enough. Wire it after the trigger if you can so it will only light up when pulling the trigger, it won't give away your position.
