I understand Bruce worked on a psychic gizmo, and I wonder if anyone else has info on a practical electronic aid or psychic kludge.

CD and tape ideas require tuning into the author's mind set (if any). Other apparatus usually is little more than a focal point while meditating. Simple white noise, for example from an off-station FM, is a meditation target, requiring the same kind of effort as without it. Running water seems useful, at least it's a "live" sound generated in the frequency range we hear. 

Perhaps a truly suitable approach would be to devise a way that spirits might "attach to" or "inhabit" in the same kind of way that they attach to people. A logical system with multiple levels of feedback and various receptors seems possible, but I know of no such devices.

Besides the obvious practical value and its potential social impact, I'm interested in building and selling such things to my patients.

Hey Dave,
Having read Miracles in the Storm and a lot of the worlditc.org website, I feel that electronic communication with the afterlife is not that easy. The technology may be there, but its only in a few hands, so far.
The spiricom device seems like an anomaly that may've been enhanced by the spiritual connection between the deceased and the receiver.
Check out the site of Sonia Rinaldi thru the worlditc.org site (click on researcher's results). This is the closest I've ever seen to two-way communication where a survivor unites with a deceased love one.
