This section has been updated for the Electronics merit badge. To complete merit badge requirement 4c, all scouts must pick up and build the radio kit before the class. (This kit is included with the $14 MBU entrance fee). You will also need to supply four AA batteries to power your radio. No soldering is required.
The bottom of the radio box has been designed with compartments to avoid losing parts. Open each parts bag only when called for in the instructions, and don't lose any parts! Building the kit will be easier and neater if you mark the number of each terminal on the cardboard underside before beginning. Install most wiring on the bottom for a neater job. Make certain to install each part with the correct polarity. When installed correctly, the flat side of each transistor should point toward the top of the schematic diagram. Also pay attention to polarity of the electrolytic capacitors (blue) and battery holder. If you encounter a problem, check your wiring and make certain that wires have not fallen out of the spring clips when others are inserted.
OTHER PREREQUISITES: Read the entire MB book, as usual. Bring the completed radio kit along along to class. (No time is available during class to troubleshoot your radio, so call if you need help. Complete requirement 6 by identifying three careers in electronics that might interest you. Be prepared to discuss these careers during class.
Please call me at 770-642-2289 with any questions you may have. Best time are on Monday or Wednesday after 4 PM, or Friday between 4 PM and 7 PM. I hope you enjoy this class and will become a great problem solver!
