<- 10-12 bit, 11 Channel A/D Converter

     Originally designed for use on Arcadia, this is the circuit schematic for an 11 channel, 10 or 12 bit (your choice) analog to digital converter. With it, you can begin putting together your own Arcadia style monitoring system, with more resolution and channels than most expensive pre-built converters.

<- Visible Light Meter

     Schematics for a visible light meter, with a similar spectral response to that of the human eye. This meter could be used alone, or interfaced with an Analog to Digital Converter, for computer logging. It has three sensitivity ranges: 0 to 350 lux, 0 to 3,500 lux, and 0 to 35,000 lux, for maximum resolution.

<- Temperature Sensor

     The same design I use on Arcadia, this is the circuit schematic for a temperature sensor. This will read the surface temperature of the sensing component, ranging from 0 to 125 degrees fahrenheit, giving a 0-5 volt output. This sensor is built to be used with an A/D converter, like the above one, for data logging.

<- Humidity Sensor

     The same design I use on Arcadia, this is the circuit schematic for a humidity sensor. This will measure the relative humidity from 0 to 100%, with an analog output from 0 to 5 volts. This sensor is built to be used with an A/D converter, like the above one, for data logging.

<- D.E.V.A.  (Dust Elimating Video Apparatus)

     Designed in 2003 at the OKCPRG Research Site, DEVA effectively removes ALL dust contamination from nightshot video. This allows for totally uncontaminated video, without false-positive out-of-focus dust orbs. Learn to build your own DEVA with just a few inexpensive parts from your local hardware store!
