Why Linear Regulators Fail Under Thermal Load
We examine the silicon die of classic TO-220 regulators under the macro lens, measuring actual thermal dissipation versus datasheet claims on an open breadboard.
Decoupling Capacitor Placement on Prototypes
Oscilloscope traces reveal how stray inductance on loose jumper wires impacts high-speed logic ICs and how ceramic bypass caps restore clean clock signals.
Breadboards never judge, and neither do we—clear pinouts and honest specs for independent makers.
No cryptic industrial part numbers or locked datasheets.
