 3+ hour class with "Lab projects".
Tentatively late April.
Projects:
Simple point to point wire solder to a perf board.
Solder a small diode and resistor to a perf board.
Test the circuit.
Solder exercises to a full plane PC Board.
Solder to a screw? Yep.
A short explanation on the Flasher Circuit below.
Assemble a simple Ultra bright LED flasher for a faux security system or just a cute toy on a PC Board.
Flashes for 4 to 9 months on a single battery. All supplies and components supplied. $12.00
If time permits, Some additional tool and test discussions.

Active Attenuator


We are planning some more FOX Hunts.

At least one will be a "Wide Area" Hunt. ie. The fox will be somewhere in the Lexington area!

(VHF FOX Beacon)
You will need a directional VHF antenna and attenuator of some sort. A perfect example is the 2m Tape Measure antenna and internal attenuator shown here. If you want to play, contact me and we can set up classes for the Tape Measure build and Attenuator. 

(Note: You can participate with only a directional antenna and some handy tricks, but it will be harder.)


AI4SR built PC Board and components installed in
the active attenuator.
(Shown below in the Tape Measure Antenna Handle.)

Schematic, PC Board, and instructions available
from me. Catch me at a club meeting or send me an email at sracing@mindspring.com.  (Tape Measure Antenna under $15 and Attenuator kit with housing under $20. )




Active variable attenuator complete. (~ 0 to - 90 dbm.)
Great for Fox Hunting with the Tape Measure Antenna.
