GWD Circuit #15-D

(6-1-1994)
 

Remarks:

(1) Keep R_in at 0 ohms, unless IC used tends to oscillate; then use minimal R_in to stabilize.

(2) Keep R_s at 0 ohms, unless meter excursions are too high.

(3) Adjust R_F (1 M variable) for best response to pendulum modulations of 0.25 cm noise, with meter out of circuit.

(4) SW₁ is unit on/off switch. SW₂ is meter on/off.

Conclusions:

(1) Unit is primarily a demo unit to illustrate: (a) Modulations of the 0.25 cm MBR with 'local' mass movements, e.g., the pendulum tests; (b) Modulation of the 0.25 cm MBR with direct 'thought' messages.

(2) Unit also serves as an electronic gravimeter unit.
