Fast, cheap, and easy to build. No soldering needed.
You need a wired home network for gigabit speed.
This little gadget will help you find both ends of your network wiring when you have a bundle of wires coming together in the basement.
It sends a pulsed 90+ volt DC signal down your CAT5 and other wires so it can give you a startling, but harmless shock if you touch the leads.
Step 1: Parts
You will also need a package of alligator clips, also about a dollar.
Get a neon voltage tester for a dollar while you are there.
Step 2: Internal Mods
- Slide off the battery door.
- Remove the batteries so you don't get shocked while clipping the leads.
- Remove the Philips screw which holds the case together.
- Cut the wires leading to the flat piezo buzzer disk.
- You will be using these wires as your test leads in the next step, so clip them right at the disk.
Step 3: Open Notch
Feed the two loose wires around the tab out through the widened notch.
Put the circuit board back in place.
Close the case and screw it back together.
Step 4: Add Alligator Clips
Attach the bare metal ends of the two short wires from the circuit board to the alligator clips.
