AI Data Centers & Local LLMs: Dave discusses his noise concerns regarding a new AI data center and its diesel backup generators being built near his office. Chris shares his experience running local AI models like Gemma 4 on a laptop using the Hermes orchestrator for tasks like coding and internet research.
USB Power Delivery Chips: Discussion of the CH224, a USB PD negotiation chip that works via DIP switches or pin strapping without requiring programming. They also touch on the CH32 X33/X35 series, which integrates similar PD functionality into a microcontroller.

The Art of (Paper) Electronics: The hosts admire Manabu Kosaka, a Japanese artist who creates 1:1 paper replicas of retro gadgets, including meticulously hand-cut lettering on SMD components. Dave also recounts his success as a “sold modern artist” after selling a printer-glitch masterpiece on eBay.

Chris’s 0201 Project: Chris provides an update on his leveling project, which features an accelerometer and 16 LEDs. He is considering a move to a rigid-flex PCB design for future revisions to better manage the two-board sandwich construction .
Social Media & Networking: Insights on using LinkedIn for professional outreach (such as contacting Massimo Banzi) versus dealing with “algorithm fatigue” . A recommendation for using chronological feeds on X and Reddit to improve the user experience .
MacService Warehouse Clearance: A massive clearance at MacService in Melbourne features rows of vintage “boat anchor” test gear . Dave expresses concern that thousands of items may end up as e-waste if not sold by the pallet.

Hyundai EV Recall: Dave recounts the recall of his 2020 Hyundai EV due to a software error that could lead to battery fires. He notes an annoying, repetitive relay clicking sound coming from the dash following the service update.
The TI Datasheet Controversy: Dave details how Texas Instruments updated process nodes and designs for classic parts like the NE5532 and OPA134 without changing part numbers. These changes led to reduced slew rates, lower maximum supply voltages (22V down to 18V), and the removal of features like trim pins.
- Dave’s Video: TI Screwed Up the NE5532
“It Happens” Segment: Dave shares a “repair fail” where he accidentally mangled the 5,000-turn drive coil of his Bulova Accutron 2 watch while attempting to change the battery.
Industry and Legal News: Brief mentions of 3D printing regulations in New York, Bambu Lab’s “closed” ecosystem controversies, and Lewis Rossmann suing Samsung over warranty issues. They also discuss Battle Born Batteries suing a YouTuber after their product failed a test conducted to its own datasheet specifications.
