What this episode covers

Ted Yapo, an engineer with a background in image processing, networking, and computer vision, discusses his diverse hardware projects, including a diode-based logic clock, a 10-year battery life LED marker, and an 8 GHz sampling oscilloscope. He explains the technical challenges of building logic gates from commodity diodes and optimizing low-power LED drivers using pulse-width modulation and inductive kickback. Yapo also details his work on a scalar network analyzer algorithm to compensate for internal leakage in cheap spectrum analyzers, highlighting the importance of test equipment in validating high-speed designs.

    James Lewis, known as Bald Engineer, details his reverse engineering of the Apple II MegaII chip to build a functional computer, explaining how he used KiCad, JLCPCB, and RP2040 microcontrollers to recreate vintage hardware. He discusses the challenges of debugging with Digilent Digital Discovery and Analog Discovery 2 tools, noting that the MegaII was likely an incomplete chip repurposed for I/O in the Apple II GS. Lewis also shares technical insights on capacitor aging, oscilloscope safety, and the importance of using test equipment correctly to avoid misleading results from logic analyzers.

    Chris Gammell, founder of parts.io, joins hosts Carl and Corey to discuss selecting the right operational amplifier for specific applications, using a 300mV DC signal and a 5nA current measurement as case studies. They also cover practical component choices like the LTC6903 programmable oscillator and the Microchip 24AA02 EEPROM with pre-burned MAC addresses. Gammell outlines parts.io's strategy to democratize access to Field Application Engineer (FAE) support by hiring an 'Internet Applications Engineer' and improving search algorithms to help small-scale designers.
