THE CURE FOR ALL CANCERS
own one you already have the circuit, probe, handhold,
speaker and test surfaces. You will just be preparing an
additional switch.Select the most suitable method for your level of experi-
ence. You don't have to do all four!The Easy Way Circuit
Build The Electrosonic Human (in the 200 in One Elec-
tronic Project Lab by Science Fair, Cat. No. 28-265, at Radio
Shack). It's easy and fun. If your kit has a different catalog
number you may have different connection numbers.
Instead of connecting the probe to terminal T2, just clip it
directly to terminal 137, and remove the 137-T2 wire. Simi-
larly, clip the handhold to terminal 76 and remove the 76-26
and 25-T1 wires. This also removes the 4.7K resistor which is
not necessary.Later, when you use the probe to press against your knuckle
you may find it painful. In this case try substituting the .005
microfarad capacitor for the .01 microfarad capacitor in the cir-
cuit.If you are using Cat. No. 28-262, you may connect the
speaker as described. With Cat. No. 28-265, eliminate the Proj-
ect Lab speaker by removing 53-173 and 54-174. Connect your
speaker instead. Positive (the short post, if using the 1/8 inch
phono jack) goes to 53, and negative (long post) goes to 54.
Finally, alligator clip the lead from the test plate shoe box to
terminal 50.
