AI Controls IPhone Via ESP32

October 14, 2026 by Zoe Skyforest 7 Comments

Do you want to get an AI agent to do something to an iPhone? You could try and jailbreak the device and do some heavy software hacking, or… you could grab a microcontroller off the shelf and have it do the hard work. [Henry Yuan] explains how to achieve this with an ESP32.

The first step is getting an AI agent access to the current state of the phone screen—which [Henry] achieves with AirPlay screen mirroring and UxPlay. A Gstreamer pipeline is then used to feed the screen as a JPEG stream to the AI agent of your choice. Then comes control, which is achieved by an ESP32-S3 acting as a USB-HID device, emulating both USB mouse and keyboard. With iOS AssistiveTouch enabled, this gives the agent control over inputs to the device. From there, it’s up to the AI agent to figure out the actions to make to achieve the desired behavior, which is obviously very use-case specific.

It might sound a little convoluted, but this approach has benefits. There’s no requirement to have an Apple Developer Account, or XCode, or a Macintosh at all. You can just get your agent tinkering away on the phone without any of that fussy overhead. We’ve featured some other great iPhone hacks of late, as well. Video after the break.

Using An ESP32-C3’s RF Hardware For DVB-S2 Video Transmission

October 14, 2026 by Maya Posch 8 Comments

Generally the DVB-S and -S2 standards require a satellite somewhere in Earth orbit to provide a signal to receive, but you can also transmit your own DVB-S2 stream with any RF transmitter if you’re so inclined. Courtesy of recent breakthroughs in using the RF hardware of the ESP32 on a raw level, [SP8ESA] has created the ESP32-DATV project using which you can broadcast a DVB-S2 signal using an ESP32-C3.

While a host PC side application handles the heavy lifting of turning the input video signal into a DVB-S(2) compliant signal, it is the ESP32-C3 that prepares the samples for transmission before sending them off to its RF block, with no external hardware needed.

If this brings to mind the idea of using an off-the-shelf DVB-S2 receiver to play back the signal, the frequency range for DVB-S2 is 10.7 – 12.7 GHz, while the ESP32-C3 is limited to roughly 2.4 GHz courtesy of it targeting only 2.4 GHz Wi-Fi and Bluetooth signals.

Using the ESP32 to transmit is already heating up.

Thanks to [ftg] for the tip.

2026 Hackaday Supercon: Workshops Are Open!

October 14, 2026 by Elliot Williams 3 Comments

Supercon is Hackaday’s annual gathering, and you absolutely need to be there.

Today, we’re pleased to announce our lineup of workshops, and it’s more than we’ve ever offered, thanks to moving to a bigger venue and to our awesome community of hackers stepping up to give them. There’s something here for everyone, so if anything strikes your fancy, be sure to book yourself a slot soon. (If you have a ticket already, you sign up for the workshop as an “add-on”, BTW.) Workshops always fill up fast, due to the small and hands-on nature of the beast.

2026 Retrocomputing Challenge: USBSID-Pico Has Two SIDs, Many Inputs

October 13, 2026 by Tyler August 9 Comments

We’ll give you three guesses what the most important bits of silicon in [LouD]’s USBSID-Pico are, and two don’t count. Yes, there’s a Raspberry Pi Pico, and a pair of the unforgettable SID chips from MOS– the sound chip of the C64, the die that launched a thousand chiptunes. Well, unless you build it with a hardware SID replacement, but the goal of this device is to get SIDs hooked up to modern hardware.

To that end, USBSID-Pico can be controlled via USB– obviously– in the form of CDC/WebUSB/WebSerial but also MIDI, and even ASID, which is a specific protocol for streaming SID register data over MIDI. You might be wondering the point, since surely you can get cycle-accurate SID emulation on an RP2040, right? Well, not everyone agrees that cycle-accurate emulation is accurate enough; like the people who swear by the subtle distortions tube amplifiers introduce into the sound, some say the chip’s own inaccuracies give the sound out of the physical device a unique vibe emulators don’t match. That’s a fight for others to litigate; we just appreciate the work that went into getting these old sound chips talking to modern hardware, and getting the project certified as Open Source Hardware.

This combination of old sound and new microcontroller makes the USBSID-Pico a good entry for our ongoing retrocomputing contest, particularly the retro-modern category. Just be aware of PAL and NTSC differences with these old chips, or your beeps and boops might be out of tune. They haven’t made them in decades, but there are more than a few modern replacements for the MOS 6581.

DECing Out The Homelab With An AlphaServer 2100

October 11, 2026 by Tyler August 7 Comments

Retrocomputer enthusiasts have a bad rap as nerds who just want to play old video games. There’s some truth in this, but the reality is that we’re nerds who want to do all sorts of things with old hardware — everything from consoles to servers. Servers like the DEC AlphaServer 2100 [derelictelectronics] picked up at Vintage Computer Festival Midwest this year. He was kind enough to record a tour for those of us who missed seeing these early Alpha machines in their heyday.

DEC did sell these units with multiple-CPU reports from the get-go, but the [derelictronics] particular model has a single CPU board carrying a 64-bit Alpha RISC processor. This machine from 1994 dates to near the height of the RISC wars when it seemed everyone needed to have their own high-end architecture, all of them RISC. While the machine could host up to 2GB of RAM, the example [derelictelectronics] found only has 256 MB, which was still not a small number for 1994!

Hackaday Links: October 11, 2026

October 11, 2026 by Tom Nardi 4 Comments

It probably goes without saying that if you send four humans to observe the Moon up close, they’ll see things that those of us stuck here on Earth have never noticed. Luckily for us, they took impeccable notes and brought plenty of cameras, which NASA has shared with the rest of the class as Artemis II: Sights & Sounds of Science.

Well, technically it’s called the Artemis II Preliminary Lunar Science Report, but we appreciate the space agency adding a little flair to it and formatting the findings for public consumption. Arguably the most significant observations detailed in the report are the impact flashes on the lunar surface. As you may recall, the trajectory of the Orion spacecraft meant the crew experienced a unique solar eclipse on the sixth day of the mission, giving them an unprecedented close-up view of the darkened Moon. During this time, they were able to see flashes of light with their unaided eyes, which NASA has since confirmed were small rocky fragments — perhaps no more than a few inches wide — slamming into the lunar surface at incredible speeds.

To boldly go where no whisky has gone before.

The Artemis II mission was one for the history books, for most of us the most significant space mission of our lifetimes. But as access to space becomes cheaper and more routine, it stands to reason that not all activities in orbit will be quite so momentous. For example, students from the University of Glasgow and Japan’s Kyushu Institute are currently collaborating on a planned mission to distill whisky in space for the first time.

Scheduled to launch in 2028, the CubeSat will carry 10 ml of fluid and spend five years in orbit studying how its chemical composition changes, with a special interest in how the frequent changes experienced as the spacecraft travels around the Earth could influence the maturing process. While this might not seem terribly interesting to teetotalers, it offers an opportunity to gain more practical experience with orbital manufacturing which will likely inform future missions.

2026 Retrocomputing Challenge: NEC 286 Laptop Rides Again

October 9, 2026 by Tyler August 6 Comments

The sad reality is that all consumer electronics are going to be e-waste eventually. [Cory Whitesell] was determined his old NEC ProSpeed 286 Laptop wouldn’t meet that fate until absolutely necessary, so when his attempts at repairs failed, his efforts pivoted to create a retro battlestation from the stylish old machine.

That screen looks too good to be stock, but otherwise you can’t tell from this angle.

Externally, it looks pretty well stock, and [Cory] has retained as much of the internals as possible. The original power supply remains intact, with power taken off the original HDD’s molex connector. Said power drives a Raspberry Pi, which is small enough to fit inside without any gutting. The original keyboard connects easily enough via a PS/2 to USB adapter, while the passive-matrix LCD has been replaced with a modern screen of the same dimensions. You’d have to be a pretty hard-core purist to mourn that last change.

With emulation on the Pi, he can still have the DOS experience you’d expect from this machine, but its also powerful enough to be useful in the modern day. While we place no bets on whether or not this mod will stay relevant for another 38 years, a more powerful single-board computer or slightly-squished cell phone can be placed in the drive bay instead once the Pi’s ARM processor inevitably starts to look as anemic as the 286 does now.

Not everyone loves this kind of restomod, but we’ve featured more than a few and have a special category for it in our ongoing retrocomputing contest for those who will do everything to keep classics out of the e-waste bin, including remaking them.
