Circuit Cellar’s technical editors purposely inserted an error in the schematic diagram. It could be a design error, symbol-related error, value error (e.g., 10k vs 100k), incorrect part usage, or some other problem that negatively affects the electronics. Find the error and submit your answer via the online form by the deadline (2 PM EST on the 20th of the month).
