Chapter 3: Electrochemistry -- Build a radio receiver, simple radio circuit

The radio needs between 1.1 volts and 1.8 volts to operate. But it also needs at least 0.1 mulliamps of current. The specifications say it needs 3 milliamps, but as you can see in the photo, we are using only 0.15 milliamps, and the radio has very nice volume. The voltage is determined by how many bowls you have.

Gold or Tin Contacts? Just don't mate them together

Whiskers, or small hairs, can form perpendicular to the metal itself and cause short circuits with neighboring metal. In high-frequency circuits, whiskers can act like antennas. Annealing, coatings, lubricants, and metal alloys can mitigate whiskering. Gold is less susceptible to whiskering, but can still create them, although of much smaller size.

How to Build Several Easy Antennas for Amateur Radio - wikiHow

Drill 1⁄2 inch (1.3 cm) holes using a good drill bit, and never drill close to the end of the pipe. About 2 inches (5.1 cm) from the end gives you a good spacing for the insulators. For the feed point, use yet another piece of PVC pipe, drilling a hole through the center to provide for a strain relief for the feedline.
