Modification of 47" Samsung TV
To overcome a thermal problem with visible image distortion after approximately 1hr, D3 added small heatsinks to the video memory chips and other IC's, plus this external fan mounted outside on the rear cover. The interior RF shield is seen under the fan blades. After a test running over four hours, the TV continued to operate without degradation-success!

We Have Light!
Prototype "breadboard" for Nixie tube circuit....power supply out of large plasma TV provides 200 vdc, with required start up logic controlled by Arduino micro-controller sequencing code. Nixie tube elements also controlled by Arduino through transistor array IC, top element illuminated in this image.

Large Nixie Tubes
An exceptionally generous gift arrived today from an old friend now in Minnesota...four large Nixie tubes plus a full set of documentation and plans. My first guess is they are Burroughs B-7971's; click on title to this post for link to more information.
Remote Telemetry Instrumentation Unit
Arduino controlled remote telemetry box including battery power supply and wireless communication module with 6 mile range. Currenlty testing with temperature logging; plans include gps, accellerometer, magnetic flux, serial jpeg camera module, and other sensors.
Shown in first test location mounted under one of our radars in the back yard.
