Oscar Liang's personal blog at oscarliang.com covers hardware. Since 2016, 8 different Hacker News readers have linked it 9 times. It is still writing: the last post was on 2026-10-31, and you can follow it by feed.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Oscar Liang's posts on FPV drone hardware and tutorials, such as flight controllers, the TS100 soldering iron, GPS-hold quadcopters and a frequency chart for analog video. Comments only cite or link them.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
FPV Drone Tutorials and Reviews, a blog for RC hobbyists to get latest information about quadcopter and multirotor products and technology development, delivered to you by Oscar Liang.
What Hacker News says?
Hmmm... I wonder if FPV goggles (from drones) could do what you want? lots of them have HDMI inputs... https://oscarliang.com/fpv-goggles/

on “Meta Horizon OS”As a note he's using an STM32F4 to drive the thing now, which is a microcontroller also used in small hobby quadcopter flight controllers https://oscarliang.com/f1-f3-f4-flight-controller/

on “Pimp My Microwave”> Why is it that the TS100 gets recommended so often? Higher temp lighter faster heat up easier temp adjustment See https://oscarliang.com/ts80-soldering-iron-ts100/ > How big of a deal is solder fumes of unleaded solder? Depends on solder, but spending $40 for not risking your health is affordable in my opinion...

on “Soldering Wires – Here's a different way”Some replies to this already, but quick notes: * "Controller" isn't used much as a term, when you start looking around. You'll see things listed under "transmitter" or "radio" * The majority of FPV transmitters use OpenTX or EdgeTX software (EdgeTX is newer and a fork of OpenTX). Both of these support plugging the transmitter in to a host computer over USB, where it can appear as a HID joystick * ExpressLRS (ELRS) i…

> can effect other people even on different frequencies flying drones and it makes spectating rather difficult (and racing in groups impossible, It’s a solved problem, spectating is supported out of the box and frequency bands have been public for a long time. Here’s a JB video with all you need to know to coexist with analog: [1] Here’s Oscar Liang’s frequency chart (updated for O3): [2] [1] https://youtu.be/P0b99J…

on “DJI – The ART of obfuscation” > How is a “rich idiot” smart enough to build a cutting edge drone but dumb enough to accidentally fly it over an Air Force base? I think a lot of people here are vastly overestimating what is required to build an RC plane that would outrun a typical helicopter. Most ARF (almost-ready-to-fly - just add your radio and a batter pack) electric-ducted-fan model planes in the $400-$600 range would be able to hit 150-200k…

on “New Details Emerge on the “Highly Modified Drone” That Outran Police Helicopters”For off-the-shelf gear, you could definitely be right. I don't know that market very well. For home-built though, you can definitely put together a rig that'll do GPS-based hover and other semi-autonomous flight modes. For example: https://oscarliang.com/gps-mini-quad/

on “It Shouldn't Be This Hard to Responsibly Fly a Drone”things generally in the same family as an arduino, such an STM32F7 based flight controller for a hobby UAV, can have features like eight UARTs and other things not found on a raspberry pi. and also in a much smaller form factor. There are some that measure 20x20mm. https://www.google.com/search?client=firefox-b-1-d&q=stm32f7... https://oscarliang.com/f1-f3-f4-flight-controller/ for instance: http://www.mateksys.com/…
