Geiger Counter Nixie Clock

by Tom Sparrow

Continuing my love of vintage and interesting items, I came across a non-working DP-66 Polish Geiger counter from 1971, which I set out to re-purpose as a Nixie tube clock.

I stripped out any unwanted electronic internals, measured and drilled holes to fit the Nixie clock module, drilled holes at the rear of the case for 2 adjustment buttons for the clock and a socket for the Power adapter.

I then removed all of the metal parts for cleaning, this was done by soaking overnight in white vinegar and wire brushing, and polished the bakerlite case with Brasso metal polish which brings back the shine like new.

The clock module was bought from Bad Dog designs, who’s customer support and service has been outstanding.
