This started as an idea to use the gage from a Geiger counter as a way to display cpu usage on my Radiation Computer, but then Strages mentioned turning a Geiger counter into a wifi detector, so I stole the idea.

  • New Geiger counters sell on Ebay for ~$60, but old ones from the 60's sell for cheaper. I hope to get one for ~$30.
  • Maybe I can use one of those little wifi detectors such as this. The power from the LEDs could be used to move the needle in the gage.


  • Purchased Geiger Counter off ebay. Link to item --JimShoe 19:50, 9 May 2007 (CDT)
  • Found a couple of wifi detectors on Amazon. #1 and #2. Some things I liked about these detectors are listed below. Let me know what you all think. Thanks --JimShoe 13:32, 18 May 2007 (CDT)
  1. #1 "Detects 2.4 GHz wireless signals generated from 802.11b/g Wi-Fi device, cordless phone, microwave oven and wireless hidden camera". Has 4 LED's.
  2. #2 can detect both WiFi and Bluetooth, and has 5 LED's.
