The ESP32 Gets A Web Browser

July 29, 2026 by Jenny List 22 Comments

At the Hackaday Europe conference in Italy earlier in the year, we were shown a rather interesting device. The work of [Alun Morris], it was an ESP32-powered Cheap Black Display board, and it was running a web browser. Definitely an achievement.

Lest you imagine that it was sporting the latest and greatest in browser technology, we must disappoint you. The browser in question is a very basic text mode device, but it did happily retrieve Hackaday, which should be the only test a browser should need to pass.

Under the hood it’s running FreeRTOS, with separate HTML retrieval and tokenizing, and UI processes. It can fetch web pages directly, but there’s also a server-side proxy for difficult sites, and for creating image thumbnails.

An ESP32 is a powerful microcontroller, but it’s fair to say it’s not in the league of running a web browser and as far as we can remember this is the first one we’ve seen. We’re sure it’s a field with further progress to be made though, particularly with the more powerful recent chips in the series. This project however is a good start, and more importantly it can be yours for a few dollars on Ali to buy a dev board. What are you waiting for?

The Need For Speed: Internet Speed Measurement (or DIY?)

July 22, 2026 by Al Williams 14 Comments

Car enthusiasts want to know how quickly they can make a quarter mile. Weightlifters are forever trying to add one more plate to the bar. Internet denizens have their own favorite number to brag about: the result from a speed test.

The ritual is familiar. Close a few browser tabs, click the big “Go” button, and watch the needle climb. Perhaps you pay for gigabit service and see 940 megabits per second, which produces a satisfied nod. Perhaps you see 299 megabits and begin obsessing over network hardware. But before you get too excited either way, try another test. There is a fair chance it will give you a different answer.

That does not necessarily mean one test is lying. “Internet speed” is not a single physical quantity waiting to be measured. A speed test measures the performance of a particular device, over a particular local connection, through a particular ISP route, to a particular server, at a particular time using a particular test method. Change any of those things and the answer can change too. Continue reading “The Need For Speed: Internet Speed Measurement (or DIY?)” →

The OpenOscar Server in terminal, with Pidgin connected

AIM-ing For A More Open Platform Than Discord

July 14, 2026 by Tyler August 30 Comments

Do you remember AIM? It may suprize you to hear that AOL’s instant messanger was actually supported all the way up to 2017– two years after Discord launched. Unlike Discord, AIM is a protocol, not a platform. Everything on your favourite Discord server is at the mercy of the corporate masters of said server; you can’t just spool up your own. Not so for AIM, as [Veronica] explains, both on her blog and in a YouTube video that we’ve embedded below.

The key is the fact that the AIM protocol isn’t locked into AOL’s now-defunct servers; it was reverse engineered in its prime for open-source messengers like Pidgin. You can host your own server, too, using the OpenOscarServer by [mk6i]. Even better, it’s not just AIM, but ICQ! In the sort of irony you only get in real life, the OpenOscar community does all its support on a Discord server. But then, they couldn’t hardly do it over AIM or ICQ these days.

For those of you who were too old or too young to get sucked into the 90s instant messenger craze, these protocols don’t just create chat rooms, that would be the even older Internet Relay Chat protocol, but usually worked more like SMS text messages. You have a contact list, and you send messages to your contacts via a server that acts as a hub. Once upon a time, that server was AOL’s, but now thanks to the OpenOscar project, it can be anybody’s computer. Of course, like texting, you can rope all of your contacts into one big group chat, and the protocol does support images and VOIP. (Which is starting to sound a lot like Discord.)

If you’re tired of your friend-group being at the mercy of American tech companies, [Veronica]’s blog post serves as a good guide to get you started running OpenOscarServer on a Linux system; she used a virtual private server but figures a Raspberry Pi ought to have enough grunt if you don’t have a huge number of people signed up.

For completeness, we should mention that while AOL pulled the plug on AIM nearly a decade back, ICQ, the other protocol supported by OpenOscarServer, lasted straight through until 2024.

Thanks to Keith Olson for the tip! Our tipsline is based on decentralized “electronic mail” technology that anyone can access.

Warp Point: A Web Ring For Gaming Sites Built For 2026

July 4, 2026 by Maya Posch 6 Comments

At one point in time web rings were one of the best ways to find content on the World Wide Web — involving not just a directory of participating sites, but also each site linking to each other in a ring-like fashion. With search results these days becoming increasingly less useful, having such a focused resource sounds better and better, with the Warp Point directory and web ring now doing just that for video game websites. Topics range from reviews to retro gaming and game development, so there’s probably something for everyone here.

For the reasoning behind this effort take a look at this article by [Wes Fenlon] and [Matt Sayer]. The inspiration was part nostalgia and part longing for the return of a simple system that Just Works™ without algorithms, advertising, ‘AI’ and corporate overlords involved at any point in time. Everything is just focused on helping you find the content and community you were looking for as quickly as possible, though spending a few hours just clicking through the ring is also perfectly fine.

Everyone is free to submit their own awesome site to Warp Point, after which it’ll be manually reviewed. Even if not strictly curated, it would seem to be a refreshing return to a more simpler time, using an approach that should still hold up just as well as it did in 1999.

Although the big commercial web directories like those on Yahoo! quickly became unwieldy and unusable, there’s a lot to be said for having these small, focused web directories and rings to regain that sense of community and humanity that’s become so scarce on the WWW in 2026.

Reviving MSN Messenger’s I-Buddy USB Accessory

June 23, 2026 by Maya Posch 8 Comments

Some of our esteemed readers were not yet out of diapers back in 2013 when Microsoft decided to put MSN Messenger out to pasture, but the memories that this instant messenger’s (IM) interface and notification sounds have left are hard to erase. This also includes some of the weirdest accessories that this IM spawned, such as the USB-connected i-Buddy. Recently [Rayly Retro] got his mittens on a new-in-box one to revive alongside an era-appropriate Windows 7 PC.

What the i-Buddy gets you is the ability to light up the head in seven different colors, twist the torso and flap the butterfly wings, all of which can correspond to certain events in the MSN IM or for more general notifications, as set by software running on the connected PC. Interestingly, this i-Buddy is recognized by Windows as a USB HID, so no special driver is needed. A range of ways to program it exist too, including a .NET-based library from back when it was still being sold for around $20.

Although the MSN Messenger network’s servers have long since been dumped into an e-waste dumpster over at Microsoft HQ, an alternative exists in the form of the Escargot service using which a range of official clients can work again.

In the video it’s demonstrated how to create a user account with the Escargot site and how to patch the messenger – here Window Live Messenger 2009 – before signing in. With that step completed, getting the i-Buddy up and running is next. This took a lot of struggling, since the version of the i-Buddy software that comes with the device didn’t like Windows 7 much. Fortunately an old forum post led to a download of version 2.10, using which the gadget jumped to life, happily lighting up and flapping its wings.

When A Favicon Becomes The Entire Website

June 21, 2026 by Maya Posch 5 Comments

Putting hidden data in places where few expect it can be a fun hobby or even a professional career. In the case of [Tim Wehrle] it’s just the former. His most recent project in this area uses a favicon image for storing a HTML-based website and rendering its contents within the browser after the favicon has been downloaded.

To pull this off, a very basic HTML page was turned into a series of UTF-8 encoded bytes that were then declared to be a standard PNG image. The original 208 byte payload plus 4-byte PNG header only used part of a 9×9 pixel favicon. With a larger favicon image as typically used you could thus easily store more data, whether as visual noise like here or a bit more hidden.

Of course there’s a catch, and in this case it’s the Typescript code to unpack the bytes from the “image” and render them; you have to load that separately. But still, in these days of all-singing, all-dancing websites that take forever to render, it’s refreshing to see what you can do with so few bytes that they fit in a favicon.

As for the purpose of such an approach, that’s left as an exercise for the reader, but you’re more than welcome to take a poke at the GitHub project and the demonstration site..

How Search Engines Enabled Finding Needles In A WWW-Sized Haystack

May 19, 2026 by Maya Posch 19 Comments

When the World Wide Web surged into existence during the 1990s, we were introduced to the problem of how to actually find something in this ever-ballooning construction zone that easily outpaced even the fastest post-WW2 urban sprawl. Although domain names provided a way to find servers using DNS rather than having to mash in IP addresses, you still somehow had to know the relevant URL.

A range of solutions were thought up over time, ranging from printed Yellow Pages type guides, to online curated lists of resources, as well as things like web rings where one website would link to a relevant similar website. This was the time when word-of-mouth was also very relevant, with people proudly announcing their own website on Geocities or other hosting service.

Search engines already existed long before the WWW became the hot new thing during the 1990s, but it was the WWW that would really push them to their limits. As anyone who used search engines for the WWW can attest, they had many issues. Often you’d end up using multiple search engines to find something, and despite fierce competition between web search engines to become the starting page for their browser, actually finding things on the WWW remained a tough problem.

Since a web search engine ‘just’ has to index the WWW and match a search query against the results, why was this such a hard problem that persisted until Google apparently cracked the code?
