Pocket Signal Generator AVR16EB28: An AVR16EB28, a 4.194304 MHz crystal and a spare pair of I/O lines make a 2 Hz to 33 MHz square-wave signal generator that fits in your pocket.
RFGEN44 Open 4 4GHz: CircuitValley's RFGEN44 pairs a PIC16 with an ADF4351 to sweep 35MHz to 4.4GHz from a 65g box. Here's how to breadboard the same idea for less.
DOGS2 Palm-Sized ESP32 Bench: Sergei's DOGS2 stuffs a programmable power supply, logic probe, frequency counter, and signal generator into one palm-sized ESP32 box. Build it this weekend.
2 Hz 33 5: One AVR chip, a keypad, and an OLED become a bench signal generator that covers 2 Hz to 33.5 MHz in 2 Hz steps — no drawer of oscillators needed.
