Now that USB-C is prevalent, it’s time for a USB-C Power Monitor. It can be used for all modern USB-C devices, as well as legacy USB devices, with the right adaptor.\u003Cbr>The RP2350B Computer by Geoff Graham & Peter Mather 28\u003Cbr>This small computer board can be purchased pre-assembled and comes with a dualcore RP2350B processor, HDMI video output, stereo audio, four USB ports, a microSD card socket, 14MiB of integrated storage, and RAM that’s expandable to over 6MiB.\u003Cbr>Series, Features and Columns\u003Cbr>How USB-C Power Delivery Works by Andrew Levido 4\u003Cbr>The widespread adoption of USB 3.2 introduced the Type-C connector, plus a new Power Delivery (PD) capability that allows up to 100W (20V @ 5A) to be delivered. It is quite a bit more complicated than previous USB power schemes.\u003Cbr>Teach-In 12.10: the World of Wireless by Mike Tooley 18\u003Cbr>This month, our focus shifts to short-range wireless devices (SRD) . These versatile chips and modules enable data transmission and reception between remote devices without requiring a wired connection.\u003Cbr>The Fox Report by Barry Fox 39\u003Cbr>A review of the new Manhattan Freesat receiver.\u003Cbr>Circuit Surgery by Ian Bell 40\u003Cbr>Measuring circuit frequency response using a PC sound card, part 11: anti-aliasing & reconstruction filter circuits. We look at multi-pole active filters using op amps. These filters are handy for reconstruction filters but have many other uses too.\u003Cbr>Max’s Cool Beans by Max The Magnificent 48\u003Cbr>Weird & Wonderful Arduino Projects, part 20: pogo pins and pixel grins. We get busy creating some test jigs and then start assembling our VFD-based countdown clock, piece by piece.\u003Cbr>Power Electronics, part five by Andrew Levido 56\u003Cbr>Power factor correction & EMI filtering – we look at circuit design rules to meet EMI regulations. We also describe how conducted EMI can be measured and investigate an example power-factor correction (PFC) evaluation board and circuit.\u003Cbr>Audio Out by Jake Rothman 66\u003Cbr>A phase-linear crossover board, plus all-pass filters, part five and final notes. We present a circuit and PCB for this special kind of active crossover for loudspeakers. We also have some more information on the NE5532 fiasco mentioned last month.\u003Cbr>Techno Talk by Max the Magnificent 74\u003Cbr>Scan me!– CynLr’s robots learn by interacting with thei","cbCaijSJUkGXFkTW","https://ap.wps.com/l/cbCaijSJUkGXFkTW","pdf",15404192,1,84,"English","en",105,"# Projects and Circuits\n## USB-C Power Monitor, part one\n## The RP2350B Computer\n# Series, Features and Columns\n## How USB-C Power Delivery Works\n## Teach-In 12.10: the World of Wireless\n## The Fox Report\n## Circuit Surgery: anti-aliasing & reconstruction filters\n## Max’s Cool Beans\n## Power Electronics, part five\n## Audio Out\n## Techno Talk\n# Regulars and Services\n## Editorial\n## Reader services","[{\"question\":\"What projects are included in this issue of Practical Electronics?\",\"answer\":\"The issue includes a USB‑C Power Monitor project (part one) and coverage of the RP2350B computer, along with additional circuit features and audio crossover content.\"},{\"question\":\"What does the series on USB-C Power Delivery explain?\",\"answer\":\"It explains how USB 3.2 Type‑C Power Delivery works, including how the PD capability can deliver up to 100W and why it is more complex than earlier USB power schemes.\"},{\"question\":\"Which circuit topic does Circuit Surgery focus on?\",\"answer\":\"Circuit Surgery covers measuring circuit frequency response using a PC sound card, with a focus on anti‑aliasing and reconstruction filter circuits.\"}]","Practical Electronics -
