News - Enginursday: Get Roving! |

If you find that radio beacon design interesting, check out VOR (VHF Omnidirectional Range). It gives the same data, but in a continuous and analog manner, encoding the bearing in a phase shift in the signal. Aircraft use it for navigation, at least if they’re not using GPS.

Suggestion for the How to Read a Schematic tutorial: mention that op-amps aren’t the only component which gets a large triangle symbol — not to list them all, but just to point out that the triangle doesn’t mean op-amp (rather the triangle with + and - marks generally does). For example, the datasheet for a microcontroller (something likely of interest for your audience) might contain in its schematic for pin/port functions a Schmitt trigger, digital buffer, or inverter.

Er, yes. My bad.
For anyone still confused: assuming you connect uniformly to the ends of a rectangular resistor, the resistance is proportional to the length and inversely proportional to the width (just like series and parallel resistors, respectively) ? so the scale doesn’t matter; this material is 1 ohm per square anything.
Er, 1 ohm per square what?
