Build a Three-in-One Measurement System

Hand-soldering a package this size
is tough work. The signal-generator
filter has bulky coils. In contrast, the
MSP430F149’s PQFP64 is tiny.

No home electronics lab is complete without a signal generator, logic analyzer, and digital oscilloscope. But why purchase the measurement devices separately, when you can build one system that houses all three? The process is easier than you’d expect. Salvador Perdomo writes: I’ve built … Continue reading
