Special electronic version bonus figure (!) Here is a digital camera photo of the apparatus. The sensor array is in the Bud box below the white firebrick, on which the two bolts (Figure 7) are placed. The sensor array is connected via ribbon cable (for signals) and coax (power) to the gold anodized box, which contains two encapsulated DC power supplies and a breakout board. The gold electronics box is connnected by a shielded cable to an A/D card in the PC, whose monitor is displaying the sensor readout.
