Step-by-step tutorial: Building a portable ghost-trapping device for your next visit

There's no better souvenir from a night at Inspiration House than a device you built with your own two hands, humming quietly on the nightstand as the old floors settle around you. Whether you take the paranormal lore seriously or simply love the ritual of it, a portable ghost-trap is equal parts craft project, conversation piece, and keepsake. This guide walks you through building one that fits in a daypack and survives the drive to Oberlin.

Gather Your Materials

Everything on this list is inexpensive and available at most hardware or craft stores, and none of it requires soldering skills beyond absolute basics. Before your visit, collect the following:

  • A wide-mouth glass jar or small metal lantern with a latch lid
  • About two feet of copper wire for the containment coil
  • A battery-powered LED tea light (never a real candle)
  • A small vibration sensor or piezo buzzer from a hobby electronics kit
  • Coarse salt, an iron nail, and a small stone such as quartz or obsidian
  • Black felt or velvet for lining the base
  • Double-sided tape, electrical tape, and a small screwdriver
  • A padded drawstring bag for safe transport

Assembling the Trap Chamber

Start by cutting a circle of felt to fit the jar's base and pressing it down firmly with double-sided tape. Pour a thin, even ring of coarse salt around the inner edge — salt has long been the traditional boundary line in folklore, and it gives your finished trap an authentic look. Next, wrap the copper wire around the outside of the jar in a neat spiral from base to shoulder, securing both ends with a drop of tape. Tuck the iron nail and stone onto the felt floor, then stand the LED tea light in the center. Close the latch lid, and the chamber itself is complete.

Wiring the Trigger

The buzzer is what turns your jar from a decoration into a device. Mount the vibration sensor to the inside of the lid using a small square of double-sided tape, keeping it flat and snug. Connect the buzzer's leads to the sensor's battery holder according to the kit's simple diagram — most hobby modules use twist-on or clip connectors rather than solder. Set the sensitivity to its lowest setting so that a passing truck or a drafty hallway doesn't send it singing at two in the morning. Test it with a gentle tap on the lid: one short chirp means you're wired correctly. If it stays silent, check that the battery is seated and the leads are snug.

Test Everything Before You Pack

A trap that fails at midnight is worse than no trap at all. Spend an evening with your finished device at home. Set it on a table, walk away, and note whether normal household movement trips the buzzer. Run it in a dark room to confirm the LED gives off enough glow to be visible from your bed without being bright enough to disturb other guests. Then pack it in its padded bag with a spare set of batteries, because cold nights and long investigations drain small cells faster than you'd expect.

Using the Trap During Your Stay

Once you've arrived, treat the device — and the house — with respect. Place it on a stable, level surface in the room where you'll spend the evening, ideally a sturdy table or trunk rather than a delicate antique. Keep a small notebook nearby and jot down the time whenever the buzzer sounds, along with anything else you noticed: a drop in temperature, a creak, a feeling you can't quite name. Never place salt or the jar itself directly on unfinished wood or fragile historic surfaces; a small tray underneath solves that. And remember the golden rule of every investigation: the house is the star, and your job is to observe, not to disturb.

After the Investigation

When morning comes, unscrew the lid, empty the salt into your palm, and give the jar a gentle wipe. Log your results while they're fresh — even a quiet night is worth recording. Many guests keep their traps on a shelf at home as a memento of their stay, recharging the salt each autumn. If your buzzer sang at 3:07 a.m., well, you'll have a story for the breakfast table. And if it didn't? That's simply a reason to come back and try again.
