What is the best way to protect my base from raids? :: Grounded ...
I''ve got tier II gear (ladybug armor, ant club, insect axe, insect hammer), and I have built a rock foundation, spike trap and a 2 story high base. But after only building it I found out about raids, and I read that you need to have the base on a rock or in the sky, but I don''t want to go through building a base again. Is there something more to help me than just spike traps?

Common Emitter Amplifier and Transistor Amplifiers
In Common Emitter Amplifier circuits, capacitors C1 and C2 are used as Coupling Capacitors to separate the AC signals from the DC biasing voltage. This ensures that the bias condition set up for the circuit to operate correctly is not affected by any additional amplifier stages, as the capacitors will only pass AC signals and block any DC component.

Unstable Capacitor
The Unstable Capacitor is a tier 3 trinket, that is obtained with a 5% chance from TAYZ.T participating in a raid. TAYZ.Ts only appear in raids if the Ominent faction is provoked through the use of a Waft Emitter. Due to this, this trinket can only be obtained after saving Dr. Wendell Tully, as Ominent factions require O.R.C. Receivers to trigger. It also cannot be obtained through …

$begingroup$ Maybe enough collector-base (or other parasitic breadboard) capacitance to get a bit of base current to flow due to the PWM signal. A smaller value for R2 or a capacitor from base to ground should eliminate the issue if that''s the cause.
safety
To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process. What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / voltage reference), meaning that if …
