$5 Geiger Counter Speaker

by on Dec.20, 2009, under Hardware

Five Below ( sells a number of amplified “iPod Speakers” for $4 – $5.  The units I picked up contain a decent audio amplifier and work surprisingly well when connected to the high impedance headphone jack of your civil defense Geiger counter.

Simply crack the case and add a panel-mount RCA jack (or connector of your choice).  Bridge the left and right channels together and connect to the line level input on the amplifier board.  Reassemble, connect, and enjoy!
