This is the Cognizance Interception Contrivance.
Made as a prop from bits of a Cyberman mask, vacuum cleaner, cutlery drainers, door knobs, bird feeders and lots of other odds and ends
The device is designed to intercept telepathic communication between demons, however it gives you a bit of headache.
Professor Arlington Periwinkle-Smythe is shown here demonstrating its use
Powered lightning combustion tubes the unfortunate a lack of demons with telepathy resulted in no evidence of devices competency,
It does blow dry wet hair as a extra feature.
