# Plug in USB, open a browser, and it's an oscilloscope: Pico.Lab hit 319 stars in 19 days, and it wasn't the performance

**What it is** An open-source firmware: flash it onto a Raspberry Pi Pico, plug it into a computer, open a browser, and you get a web desktop with an oscilloscope, logic analyzer, power supply and bus tools.

**Why it took off** "Plug in USB, open a web page, it's an instrument" can be explained in one sentence and understood from one image, and an old Pico in a drawer is enough to try it. The author is a familiar face at Hackaday, and English hardware media and Chinese recommendation accounts amplified it in several waves.

**B** **How you could follow it** Take the "onboard web page + USB virtual network card" trick to other small tools that normally need desktop software (the most obvious gap is a browser-based JTAG/SWD debugger). Keep it running on cheap off-the-shelf boards, and at launch put the video, hackaday.io and Hackster out together before pitching Chinese recommendation accounts.

Grade B: the delivery method is copyable and there are still few competitors, and the path to follow is clear. But the ceiling is a few hundred stars, and half of the reach came from the author's years of accumulated media credibility, which newcomers can't easily replicate at the same density. What the small circles are saying

Data (updated daily) · Repo created 2026-10-18 · 327 stars · 7 days +129

GitHub · stars

Data 2026-10-22 → 2026-11-08 (18 days, 17 observations). Points before 10-28 come from deeply / archive backfill, not every day has one

A German hardware author turned the $5 Raspberry Pi Pico into a "workbench in the browser": oscilloscope, logic analyzer, power supply and bus tools all in one web desktop, with no software or drivers to install. It's an order of magnitude weaker than commercial instruments, yet it got 319 stars in 19 days and was covered by Hackaday, Hackster, Adafruit and Chinese electronics media. Here's how it got going, and whether you can use the same playbook for your own project.

### A line in the Hackaday comments defending itself

On the morning of Oct 30, 2026, the Hackaday front-page article "Is This The Only Instrument You Need?" already had a dozen-plus replies arguing beneath it. Someone read the firmware: "Everything is stuffed into one C file of about 2,900 lines." Someone else was blunter: "Looks like it was slopped together by AI." 6:28, the author Max Kern replied himself:

> "In my defense: the hardware, art, concept, testing and optimization were all done by hand. I deliberately wanted to see how far AI could get me on web design and firmware."

The argument didn't hurt the project. The day after the Hackaday article ran, it gained 52 stars on GitHub in a single day (from 129 to 10-31 on 10-30, 181). Editor Jenny List praised just one thing in the body: "Perhaps the cleverest part is its interface."

### What it is

Pico.Lab is an open-source firmware plus an optional custom board. Flash the firmware onto a Raspberry Pi Pico or Pico 2, and when the board is plugged into a computer it shows up as a USB virtual network card. Open `http://pico.lab` in a browser and you get a "desktop" with draggable, resizable windows, containing:

- A 4-channel oscilloscope (bandwidth about 400kHz, written by the author himself)

- A 8-channel logic analyzer, up to 100MS/s, able to decode UART / I2C / SPI

- GPIO control, data logging (CSV export), serial terminal, I2C / SPI host

- Adjustable power supply and current monitoring (requires his custom board)

The whole front end is about 200KB, built with vanilla JavaScript plus a window library called WinBox.js, with no framework dependencies, all stored in the board's flash. The README is candid: "This runs on a 1 dollar microcontroller over USB 1.1. Don't expect professional instrument performance."

His reasons for building it are also specific. The first paragraph of the hackaday.io project page says that when working on hardware he had no room on the bench, so he got used to small tools like the Saleae logic analyzer and the Nordic PPK2; existing all-in-one projects were "either expensive, hard to use, or command-line only." As for the "plug in USB, open a web page" trick, he learned it from the web configurator of a gamepad firmware, GP2040-CE. The first time he used it he was amazed: "No Wi-Fi, how is it opening in the browser?"

### Over 19 days, how the stars stacked up wave by wave

| Date | star(GitHub) | What happened those days |
|---|---|---|
| 10-18 | 0 | Create the repo and release the 1.0 firmware |
| 10-20 | – | YouTube launch video, hackaday.io project page with dev logs, enclosure files uploaded to Printables |
| 10-21 | – | Hackster.io project page; a Japanese FabScene write-up; an X post with 8.8k views |
| 10-22 | 24 | A Japanese user modified the config and ported it to the smaller RP2040-Zero |
| 10-24→25 | 50→89 | Hackster's X post (10-23), a Reddit r/embedded post (date unverified) |
| 10-26→27 | 98→105 | Adafruit blog and its X post |
| 10-30→31 | 129→181 | Hackaday front-page article, 30 comments |
| 11-02 | 201 | Chinese GitHub project recommendation account @QingQ77 posted, 33k views, 638 likes |
| 11-03→04 | 248→305 | The Chinese recommendation post took off; a long-form article from Electronic Engineering Album (EET-China); 11-04 gained +57 in a single day, the peak |
| 11-05→06 | 316→319 | Cooled off, single digits per day |

Three things stand out:

**First, it was built from several media pulses, not one burst.** This round of English hardware media (Hackster → Adafruit → Hackaday) brought in roughly the first 180; the biggest single-day peak actually came from the Chinese sphere, where one recommendation post plus one long Chinese article added +104 in two days. Many names in the fork list are clearly Chinese users.

**Second, it didn't make GitHub trending or Hacker News.** Reaching the 319-star level relied entirely on vertical circles: hardware maker media and Chinese and Japanese GitHub repost accounts.

**Third, stars and real users differ by an order of magnitude.** From 1.0 to 11-06, the three firmware files were downloaded about 170 times in total (69 for the standard Pico build, 2 for the Pico 70 build, 30 for the custom board build). Many people starred it as "this trick is clever, bookmarking it" rather than "I've tried it." The launch video has 30k views on YouTube (11-06), and the author's channel has 4,240 subscribers.

### Why this one

**It can be explained in one sentence and understood from one image.** "Plug in USB, open a browser, and the window is an oscilloscope": nearly every outlet's headline and lede says this line, and nobody is praising its sampling rate.

**You can try it right away.** No need to buy his board; the Pico gathering dust in your drawer can run it with the uf2 file. The author wrote this point into the project page: he found his hobby projects increasingly depended on custom PCBs that others couldn't replicate, so this time he deliberately made the firmware run on any off-the-shelf Pico. When readers can get their hands on it, they have a reason to share. Two days after the video went up, a Japanese user had already ported it.

**The author is a familiar face.** Max Kern (GitHub name CoretechR) has 11 repos with about 2,500 stars in total. He previously made the open-source remote OMOTE, the NiMH charger SPINC (covered by IEEE Spectrum), and the hexapod robot ZeroBug, all of which were featured on Hackaday. The editors know him, so three hardware outlets covered him within ten days. Followers can't get this, at least not at first.

**The AI controversy is also traffic.** The README openly admits that much of the firmware and front end was written with AI, and the Hackaday comments argued for twenty-plus replies because of it. Some called the code messy, while others said "I had a nearly identical project that took me weeks to write, and Claude did it in 20 minutes." The argument itself got more people to click into the repo to see how good the code actually is (inference).

**The topic is hot.** The RP2350 is a popular maker-scene chip from 2026. The same month, an Australian team's Picotronix was crowdfunding on Kickstarter, also using two Pico 2 boards for an oscilloscope and logic analyzer, but it was paid and had its own screen. The "using a Pico as an instrument" trend is heating up.

### Who it's competing with

| Project | Stars / scale | Difference from Pico.Lab |
|---|---|---|
| gusmanb/logicanalyzer | 5,052 | Logic analysis only, 24 channels, requires desktop software |
| sigrok-pico | 1,121 | Turns the Pico into a capture device for PulseView, requires PulseView |
| RP2350_Logic_Sniffer | Not checked | 27-channel logic sniffing, people in the Hackaday comments compare it |
| Bus Pirate 5 | firmware 273 | Also an RP2040/2350 bus tool, but command-line only, and you have to buy hardware |
| Glasgow Interface Explorer | 2,233 | FPGA approach, strong performance, high toolchain barrier |
| Scoppy | Android App | Phone as the screen, 2 channels, you have to install the App |
| Analog Discovery 3 / Saleae / PPK2 | Commercial | An order of magnitude faster, from $200, needs vendor software |

On any single feature, it isn't the strongest. On logic analysis, gusmanb/logicanalyzer has 5,000 stars and three times the channels. Pico.Lab wins on how it's delivered: **no one else combines driver-free use, a browser-window interface, flashing onto the stock Pico, and does all the functions.** The criticism in the comments also centers on the same spots: too few channels, USB 1.1 too slow, the web UI less professional than desktop software. Those are exactly the gaps a follow-up project can fill.

There's no functional clone on GitHub yet. The 35 forks are basically empty. One app called "PicoLab", a circuit-teaching app, hit the app stores in November, just by name collision.

### If it were you

**Verdict: B, worth trying.** "Onboard web UI + USB virtual NIC" is a delivery trick that's easy to copy and rarely used, and it can be carried over to many tools. But this project's ceiling is a few hundred stars, and half of its success rests on the author's years of accumulated media credit. A newcomer copying it will most likely not get the same press coverage.

**Who it suits** : people who can do embedded work and have a small tool idea that "would normally need a host app installed"; ideally someone who already has projects on hackaday.io, Hackster, or the Chinese open-source platform OSHWHub, or on Bilibili. If you can write long-form Chinese articles and know the Chinese GitHub recommendation accounts, even better: this project's biggest day came from the Chinese-speaking community.

**Who it doesn't suit** : anyone aiming to reach thousands of stars with one project (this is a niche hardware community, and 319 is already a good result); anyone who doesn't touch hardware and only writes web code (the barrier for this trick is the TinyUSB + lwIP layer, which the author says took a long time to get working); anyone trying to head-to-head on performance, building a "better Pico oscilloscope" (you won't beat logicanalyzer or commercial instruments, and media won't write about you just for a higher sample rate).

**How to do it** , three paths, starting with the most worthwhile:

1. **Carry this trick over to other tools.** The most obvious gap is the JTAG / SWD item the author lists in his to-do: a Pico debugger you plug in and then flash and debug from the browser. There are also things like servo testers, sensor configurators, CAN / RS485 capture, and battery internal-resistance testers, all of which "currently need a small app installed." You could also swap chips: ESP32-S3 and China's CH32 series have USB device capability, and there's a large stock of ready-made boards in the Chinese maker community (inference).

2. **Do the parts it does poorly.** The comments are clear: not enough channels (16 or 24), capture depth too short, and people want a signal generator and IV curves (the Analog Discovery kind of feature set). Add that on top of Pico.Lab's web UI approach, or pair a driver-free web front end with a strong project like logicanalyzer.

3. **Build a Chinese-language version.** Chinese UI, Chinese docs, and boards that cost a few yuan on domestic Taobao.

Whichever path you pick, follow its pattern: **it must flash onto off-the-shelf, cheap boards** , and only the enhanced version uses custom hardware; the interface should feel like desktop software, with a screenshot that makes sense at a glance.

**Getting users** : release everything at once, matching its launch rhythm: GitHub 1.0 firmware, a YouTube demo around 3 minutes (plug in, open the browser, get a waveform; put this shot first), a hackaday.io project page with two or three dev logs, Hackster, and Printables for the enclosure. Then submit a tip to Hackaday, pitch the Chinese GitHub recommendation accounts and EET-China's column "面包芯语", and for Japan try FabScene. If you used AI, state it in the README as he did; controversy isn't a bad thing.

**Timing** : the idea of a Pico as an instrument was hot in 2026 October, and Picotronix's crowdfunding was running. Best to ship before Q1 of 2027; once Raspberry Pi releases its next-generation chip, maker-media attention will shift (inference).

**What would prove me wrong:** ① Over the next month or two, two or three similar "USB web UI + Pico" projects appear, all with very few stars. That would mean the trick is no longer novel and media has stopped writing about it. ② Pico.Lab itself stalls at three or four hundred stars and its firmware downloads stay flat. That would mean it's a one-time curiosity collect, not real demand. ③ Conversely, if Pico.Lab quickly gets PRs adding JTAG and more channels that get merged, the author has filled the gap himself, and the 2 path gets narrower.

A final note for anyone who wants an open-source project to get stars: Pico.Lab shows that in the hardware community, **"how it gets into users' hands" can itself be the whole selling point of a project** . Next time you build a small tool that needs a driver and a host app, first ask whether it could just open in the browser when plugged in.

## CoretechR/PicoLab (Pico.Lab) research report

> Research date: 2026-11-06 | Channel: GitHub | Data card: `gh_CoretechR/PicoLab`

### One line

Pico.Lab is an open-source embedded debugging "multi-tool instrument" by German hardware enthusiast Maximilian Kern (GitHub CoretechR, hackaday.io Max.K). Once the firmware is flashed onto a Raspberry Pi Pico / Pico 2 (RP2040/RP2350), the board appears on the computer as a USB virtual network adapter. Opening `http://pico.lab` in a browser gives a windowed "desktop" with a 4-channel oscilloscope, a 8-channel logic analyzer (with UART/I2C/SPI decoding), GPIO, data logging, a serial terminal, an I2C/SPI host, and an adjustable power supply (the power function needs a matching custom board). No host app to install, no drivers. Its growth came from "a veteran maker author + organic pickup by hardware media + Chinese and Japanese X repost accounts", with no trace of paid promotion. Stars are not revenue, and the project itself is not commercialized.

### 1. Data

- GitHub (our github repo / data card, 2026-11-06): repo created 2026-10-18,19 days ago, 319 stars (gh API now shows 322), 35 forks; last 7 days +190, first 7 days +105; single-day peak +57 (11-04). Never made trending, and the repo is under 60 days old, so it doesn't qualify.

- Cumulative downloads across three uf2 release builds of Release 1.0 (10-18 release): standard Pico RP2040 build 69 times, Pico 2 RP2350 build 70 times, custom board build 30 times (gh API, 11-06). So the people who actually flashed the firmware and tried it number in the low hundreds, an order of magnitude below the star count.

- Launch video on YouTube, "Pico.Lab - Web-GUI Embedded Multitool" (released 10-20): 30,113 views, 503 likes, 35 comments (YouTube Data API, 11-06). The author's channel has 4,240 subscribers and 667k total views.

- Author background: the CoretechR account has 11 public repos with about 2,500 stars in total. Past projects include the OMOTE open-source remote (1,807 stars in a community repo), the SPINC NiMH charger (467 stars, featured in IEEE Spectrum), the ZeroBug hexapod robot (304), and Zicada (205). He was already a regular contributor on Hackaday.

#### Star curve and event correspondence (daily from data card)

| Date | star | Daily increase | Events in the same period |
|---|---|---|---|
| 10-18 | 0 | – | Repo created, released 1.0 |
| 10-20 | – | – | hackaday.io project page + YouTube video launch, enclosure uploaded to Printables |
| 10-21 | – | – | Hackster.io project page; Japanese FabScene coverage, its X post with 174 likes / 8.8k views |
| 10-22 | 24 | – | Japanese X user reposts, someone modifies board_config.h to port it to RP2040-Zero |
| 10-23 | – | – | @Hacksterio X post (4.1k views) + LinkedIn |
| 10-24→25 | 50→89 | +26/+39 | Picked up by Hackster and FabScene; r/embedded post "I built an RP2350 multitool that hosts its own desktop-style web UI" (date and score unverified, reddit blocked scraping) |
| 10-26/27 | 98→105 | +9/+7 | Adafruit blog (10-26) + @adafruit X post (6.2k views), reposted by TinkerNews and DevFeed |
| 10-30→31 | 129→181 | +52 | **Hackaday homepage article** "Is This The Only Instrument You Need?" (Jenny List, 10-29 evening, 30 comments), with aggregators like daily.dev and syslog.gr following up |
| 11-02 (Beijing time 09:14) | – | – | **@QingQ77 (Geek Lite, a Chinese GitHub project recommendation account)** posted: 638 likes / 69 reposts / 33k views |
| 11-03 | 248 | +47 | The Chinese recommendation post took off; the KiCad Rookie blog wrote a PCB teardown |
| 11-04 | 305 | +57 (peak) | **EET-China (Electronic Engineering Album) "面包芯语" Chinese long-form article** |
| 11-05/06 | 316→319 | +11/+3 | Heat fades |

Takeaway: the curve is several rounds of "media pulses" stacked on each other. The English hardware press round (Hackster → Adafruit → Hackaday) drove roughly the first 180 stars; the Chinese round (the Geek Lite X post + EET-China) drove the biggest single-day peak and about the last 120 stars. The fork list also shows clearly Chinese users (manmuqingshan, lycsqq, xiaolitongxue666, feiyi26, etc.).

### II. Competitors

| Competitors | Form | Launched | Scale | How it differs from Pico.Lab |
|---|---|---|---|---|
| gusmanb/logicanalyzer | Open source (RP2040/2350) | 2022-07 | 5,052 star | 24 channels, 100Msps, logic analysis only, requires a desktop app; Pico.Lab has fewer features but everything runs in the browser and it covers it all |
| pico-coder/sigrok-pico | Open source | 2022-02 | 1,121 star | Turns the Pico into a sigrok/PulseView capture device; requires PulseView; no power or bus tools |
| RP2350_Logic_Sniffer(rabbitholecomputing) | Open source | – | Not checked | 27-channel logic sniffer; Hackaday comments have people comparing it to this |
| Scoppy | Android App + Pico firmware | Around 2021 | Has a reasonable install base on Play (unverified) | Phone as the screen, 2 channels; requires installing the App |
| Bus Pirate 5(Dangerous Prototypes) | Open-source hardware + finished unit around $40 (unverified) | 2023 | Firmware repo 273 stars | Also a multi-function bus tool on RP2040/2350, but command line only; the Pico.Lab author points out that existing projects are either expensive or command line only |
| Glasgow Interface Explorer | Open-source hardware + crowdfunded finished unit | 2018 | 2,233 star | FPGA-based, powerful, but needs a Python toolchain install, high barrier to entry |
| Tigard | Open-source hardware | 2020 | 894 star | FT2232H multi-protocol adapter; no scope and no graphical UI |
| Picotronix (Thort Werx, Australia) | Kickstarter crowdfunding | late 2026-10 | Crowdfunding in progress | Appeared around the same time, also built on two Pico 2 boards doing modular scope + logic analysis, with a built-in LCD/WiFi/Bluetooth/phone App, paid; Pico.Lab is free, browser-based, and runs off a standard Pico |
| Digilent Analog Discovery 3 / ADALM2000 | Commercial USB instrument | Years | Mainstream | An order of magnitude higher performance, $200–400, requires installing software like WaveForms |
| Saleae Logic, Nordic PPK2 | Commercial | Years | Mainstream | The author's own stated inspiration and the thing it replaces: single-purpose, high price |
| GP2040-CE web configurator | Open source (gamepad firmware) | 2022-12 | 2,589 star | Not a competitor, but **the technical inspiration** : the trick of a USB virtual network adapter plus an on-board web page is something the author learned here |

No competitor does all four of these at once: driverless, a browser-window-style GUI, runs off a standard $5 Pico, and has scope / logic / power / bus all together. On performance it is behind across the board (the author admits a 400kHz bandwidth and USB 1.1).

### 3. Growth tactics (evidence)

1. **Author's own channels + established author credibility** (confirmed): YouTube video with 30k views; hackaday.io project page with dev logs; also uploaded to Hackster.io and Printables. Kern's earlier projects have been on Hackaday and IEEE Spectrum several times, so media editors know him.

2. **English hardware press chain** (confirmed): Hackster.io (10-21, X + LinkedIn), Adafruit blog + X (10-26/27), Hackaday front page (10-29,30 comments), then aggregators like daily.dev, DevFeed, syslog.gr, and TinkerNews picked it up automatically.

3. **Japanese circles** (confirmed): FabScene coverage (10-21), X post with 174 likes / 8.8k views, Japanese users followed up with ports.

4. **Chinese X recommendation accounts + Chinese electronics media** (confirmed): @QingQ77 11-02 posted with 33k views and 638 likes, corresponding to +104 stars over 11-03/04 two days; EET-China ran a long-form piece from 面包芯语 11-04.

5. **Reddit r/embedded post** (partially confirmed): the post's title and link are in search engine indexes; date and score unverified.

6. **Hacker News** : neither Algolia nor our hackernews library turned up anything (stories with ≥5 points); HN was not a source.

7. No ads, no crowdfunding, no board sales (no Tindie or store page found).

### 4. Why it made the list

- **The "magic moment" in the experience can be screenshotted and explained in one sentence** : "Plug in USB, open a browser, and a scope appears in a desktop-style window." Nearly every media headline uses this line (Hackaday's own words: "Perhaps the cleverest part is its interface").

- **Zero-barrier trial** : no custom board needed; a Pico sitting in a drawer just needs the uf2 flashed to work. Readers can get hands-on right after reading, which gives them a reason to share (Japanese users ported it to RP2040-Zero the same day).

- **Long-built media credibility** : several projects previously ran on Hackaday / IEEE Spectrum, so Hackster, Adafruit, and Hackaday all covered it within 10 days of each other.

- **AI acceleration + public disclosure** : the README openly admits that much of the firmware and front end was AI-generated. This sparked controversy in the Hackaday comments (people calling the code messy, "slop"), which in turn drove discussion. It also explains how one person in their spare time built such a complete GUI.

- **Timing** : The RP2350 ecosystem was hot in 2026 (lots of HN stories about RP2350); the same month Picotronix ran a Kickstarter, and the "Pico as an instrument" idea was heating up.

- **Secondary amplification via Chinese GitHub recommendation accounts** : the biggest single-day gain came from the Chinese community, not the English launch.

### 5. Differentiation

The differentiation is not in performance but in how it's delivered. It moves the on-board web page plus USB virtual network adapter trick (RNDIS/ECM + lwIP + SSE) from gamepad firmware (GP2040-CE) onto a measurement instrument, then uses WinBox.js to build a multi-window desktop. The whole front end is 200KB and depends on no framework. Competitors either offer only a command line (Bus Pirate), require installing PulseView or vendor software (sigrok-pico, logicanalyzer, AD3), or require buying dedicated hardware (Picotronix, Glasgow). **This is why it took off** : the core selling point in media coverage and the Chinese recommendation posts was "no software to install, just open it in a browser"; nobody was praising its sample rate.

### 6. Visibility and copycats

- Visibility: **it's circulating in small circles** . Maker-hardware media (Hackaday, Hackster, Adafruit, EET-China) have all written about it, and the Chinese X recommendation account got 33k views; but it hasn't reached HN or GitHub trending, and no big accounts in the AI / startup scene on X are talking about it. With no revenue, the revenue question doesn't apply.

- Copycats: no functional clones yet. There is an unrelated app with the same name, "PicoLab" (a circuit simulation teaching app by Claire Nicholson, launched on Google Play / App Store in early November), which is just a name collision. About 35 forks, mostly empty forks.

### VII. What to take away

- "On-board web page + USB virtual network adapter" is a reproducible delivery pattern: any MCU hardware tool (programmer, debugger, sensor configurator) could be driverless, cross-platform, zero-install, and the demo effect is very strong.

- Supporting an already widespread off-the-shelf board (Pico) lowers the trial barrier; the custom board is just an "enhanced edition". This lets readers get hands-on immediately, which gives high sharing conversion.

- Launch all at once: video, hackaday.io dev logs, Hackster, Printables, GitHub, so editors have material to work with; then wait for the Chinese and Japanese reposts to amplify it again.

- Build a complete GUI fast with AI and disclose it publicly. The controversy itself is traffic.

### 8. Not sure

- Post date and score of the r/embedded thread (reddit 403).

- Whether the author will sell a custom board or run a crowdfunding campaign (none seen so far).

- Conversion from stars to actual use: cumulative firmware downloads are only about 170.

- Whether there are WeChat Official Account or Bilibili reposts in the Chinese community (no specific posts found).
