Digital Wattmeter - The extra input B is for a later SWR brigde project,
also the TX serial output will be in use later. The uncalibrated signal response is:
+1/-1 dB from 1MHz to 450MHz. Input SWR vill varry from 1.00 to 1.30, depending on
input frequency. To make the SWR this good, you need to assemble the input circuit
correct and adjust the capasitor. Input power range: -60 to +30dBm that is 1 nW to 1
Watt. ….... |

Watt-Hour Meter Monitor - This is a simple and safe way to monitor the power
and energy use of a typical home. A battery powered device is attached to the
top of a typical spinning wheel type watt-hour meter. The device contains a
visible red LED and a PIN photo diode. Light pulses are bounced off of the
watt-hour meter’s spinning wheel. The circuit detects the black mark on the
wheel and produces a clean TTL level logic signal, equal to the frequency of the wheel
spin. This information can be connected to a low power RF transmitter to send to a
matching receiver, where the information can be recorded and displayed. …. [Hobby
