Procrastineers Rejoice! 2026 Supercon Call For Participation Extended

A few weeks ago, we put out the call for participation for this year’s 2026 Hackaday Supercon, taking place in Pasadena, CA this November. Today was going to be the deadline, but like you, we often let things pile up and put things off, so we’re extending another two weeks until August 26th.

Which is not to say that we haven’t heard from a ton of you! We’re psyched to see so many familiar Supercon regulars on the list, but we also love to see first-timers give talks. We try to make sure that new folks get their time to shine, so if you’ve never given a Supercon talk before, or if it’s been a few years, take this as your cue to present in front of the friendliest audience of like-minded hackers around.

This year is Hackaday’s tenth in-person Superconference, and to celebrate we’ve gotten a larger venue, so more folks can watch the talks live. We’ll be running two tracks as always, and you have your choice of a 20-minute or 40-minute slot. Presenters get in free, and we’ll get you an early-bird ticket rate the submission, so don’t delay and register for your slot today! Or at least before August 26th, because we won’t extend the deadline twice.

Oh, and if you’re interested in tickets, swing by Hackaday about this time tomorrow — we’ll have some news for you.

Retrotechtacular: A View Of The Moon From 1964

If you didn’t live through it, it is hard to understand how excited the general public was about the race for the moon. You can capture some of it by watching “Lunar Bridgehead,” a film about JPL monitoring the Ranger spacecraft as it hit, rather hard, on the lunar surface.

The Ranger program had been plagued with problems. The first five didn’t make it to the moon. Ranger 6 hit the moon, but failed to start its cameras. Ranger 7 was the first successful mission. There would be two more successful missions before the end of the program.

Hackaday Links: August 9, 2026

Bad news for anyone who was hoping for some relief from the memory shortage — Digitimes is reporting that the production capacity of major players such as Samsung, Micron, and SK Hynix has already been booked for 2027 due to record demand. Their industry sources indicate that what we’re experiencing currently is just a prelude to when things get really ugly, which is why customers are paying a premium to lock in their orders so far out.

Although there’s been no official word from either side of the transaction, the Digitimes article further points out that these sort of agreements are usually 3 to 5 year contracts. If that’s the case, and nothing changes in supply and demand equation, we could be in for a very rough ride. There’s a potential opportunity here for other manufacturers to step in and start producing DRAM, possibly even focusing on lower-performance offerings intended for the consumer market, but setting up those production lines isn’t going to happen overnight. It’s always possible the AI bubble could pop in the next couple of years, but we’re not sure we’d put money on it.

There’s a developing story this weekend about the breach of customer data over at Framework. The maker of modular and repairable computers has recently sent an email out to all customers that their names, email addresses, phone numbers, and physical addresses were leaked due to an upstream zero-day attack against database provider Metabase.

Metabase disclosed the breach on August 3rd, but we were mildly surprised to see that Framework doesn’t seem to have made any public acknowledgement of the event so far. As far as we can tell, the only reason there are copies of the email from them circulating online is because several customers posted it to social media. In their statements to sources such as TechCrunch, Framework reps were also hesitant to give hard details such as how many customers were impacted. While we’re fans of what Framework is trying to do in terms of hardware customization and repairability, we have to admit that being cagey about this sort of thing isn’t a good look.

Hacking A $6000 Cotton Candy Machine To Fully Control It

Some of the cotton candy options by the machine. The Chinese text reads 'flower type'.
Some of the cotton candy options by the machine. The Chinese text reads ‘flower type’.

Having a fully automated cotton candy vending machine in your possession is a great thing, but not if you do not have full access to its software. With [Block’s Retro Repairs] getting ghosted by the manufacturer on regaining account access to the machine he bought used for $300, there was little left but to try and break into the system.

We previously covered the journey in getting the vending machine back into a state where it’d actually reliably produce cotton candy again, a process which is quite tedious and temperamental. After a lot of fiddling with sensors and temperature settings this was fixed, but still left the issue that as a vending machine it should allow the owner to set prices and such. Sadly this could only be done remotely via a special account, which access to had been left with the previous owner.

Despite the very custom exterior, the vending machine runs what is effectively an Android system, consisting of an industrial computer board wired into a lot of stepper drivers and other control boards. To the extreme delight of everyone involved, it was possible to access the Ct Terminal application with adb and its product database on the device’s storage. Unfortunately writing back a changed database file didn’t change anything in the UI, so for a few months the project languished.

After nearly bricking the system and ending up factory resetting the control software including temperatures, it actually improved the performance of the machine and produced cotton candy, so that was one win. Ultimately the solution was to modify the original app, but a combination of weak coding skills and the app being in Chinese  led him to use free LLM coding chatbots to assist here.

This resulted in a custom settings menu being added with the ability to modify pricing, no need for online access any more and a very nice cotton candy vending machine for the private arcade where presumably friends and family can enjoy cheap or even free cotton candy. Finally having the machine sealed against ant intrusion was also a major improvement.

Full Teardown Of A 2026 Amazon Fire Stick HD

After the release of Google’s Chromecast so-called ‘streaming sticks’ have remained a popular form factor, even though such technology is these days part of ‘smart’ TVs. Being curious as to what kind of hardware they put into these sticks or dongles these days, [electronupdate] decided to do his typical full teardown of a 2026 model Fire Stick HD from Amazon, including the typical nekkid die shots.

Although most of the bits inside are fairly typical, being just your typical Mediatek-sourced solution, the ceramic patch antennas for Bluetooth and Wi-Fi are a rather interesting detail, as are the purported limitations that make this the ‘HD’ version of the Fire Stick, unlike its 4K brethren.

The used Mediatek MT8698D SoC isn’t so different from the SoC in those 4K versions, with the 2025-era 4K Plus using the MT8696D, but the 4K Select using basically the same SoC as the HD version, featuring the same G310V2 GPU at 500 MHz per the Amazon Developer documentation and the same decoder block (VPU), both of which are capable of 4K video decoding. This implies that the HD vs 4K distinction is purely software-based.

After popping open the device and noting the various ICs, the NAND Flash, the Mediatek MT7902 wireless IC, the PMIC and the aforementioned SoC all have their caps popped in order to take a closer look at their dies. For reference, as one of the largest ICs, the SoC die is a mere 5.2 x 6.45 mm. The PMIC die is more interesting as usual, as this one integrates USB-PD functionality, adding quite a bit of logic to what is otherwise a fairly mundane bit of power management features.

Overall not a very surprising design, though it does tickle that thought in the back of one’s mind whether it could be turned into a ‘4K stick’ with a few software tweaks, or perhaps more simply by installing plain Android onto its 8 GB of eMMC.

Addressable LEDs Make Giant 16×2 Character Display

We’ve always taken a certain childlike joy in seeing tiny things made big, and big things tiny. Evidently [Uncle Stem] is the same way, if this 7x sized 16×2 “LCD” display is any indicator.

“LCD” is in scare quotes there, because while the original display is a character LCD, [Uncle Stem]’s embigginated recreation is not. Liquid crystal displays are beyond all but the most dedicated DIYers, so [Stem] recreated the whole thing with addressable LEDs instead — over a thousand of them. Each character got its own PCB, and rather than pay for assembly [Stem] used a 3D printed stencil to help apply solder paste, an idea we’ve seen before. His choice of long lengths of nickel strip — the stuff you spot weld to Li-ion batteries — to join the LED-holding PCBs is also worth noting.

In order to get his giant display to act like the I2C-operated module he loves, [Uncle Stem] equipped it with an RP2040 pre-programmed with the LCD character set. That way he can plug it into any Arduino project that uses the LiquidCrystal_I2C library and have the authentic 1602 experience. The green “PCB” the display is mounted to is actually laser-cut plywood, while some acrylic sits in front of his PCBs with office paper to act as as a diffuser. A 3D printed frame completes the illusion. He even goes so far as to replicate the pin headers at 7:1 scaling with brass rods.

He also connects it to a over-sized Arduino, with giant jumper wires. But for the record, not the giant Arduino we featured previously. Like we said, hackers like to mess with scale, and we’ve seen everything from giant benchies to a working Mac Classic for Barbie.

Train Simulator Controller: July 2026 Progress Roundup

For the past three years [Christopher Mitchell] has been working on his replica of a British Rail Class 800 control cab for a physical train simulator, with the July blog update providing many details on the progress.

The Class 800 series of trains is relatively new, having first entered service in the UK in 2017 on the Great Western Railway (GWR). Designed and built by Hitachi as part of their modular AT300 product series, they come in both purely electrical and diesel-electric hybrid configurations to deal with non-electrified rail sections.

Replicating the experience of driving a train is always a trade-off between what one would like and what is practical or affordable. With only a corner of his apartment to work with, [Christopher] has opted to focus on the instruments and controls in the cab, using real components where possible or building replicas for the remainder.

This entire control panel is to be used with simulators like Train Simulator and Train Sim World, using their controller APIs to both control the in-game train as well as to get feedback to be displayed on the real instruments and the various LEDs, such as those that indicate the state of the external lights. These are all controlled internally via a CAN bus, as is typical.

These instruments include genuine AWS sunflowers, part of the safety system that ensures that a driver has acknowledged a non-clear signal along the track. It’s another nice touch to a control cab simulation that’s shaping up to be rather close to the real deal.

Even if for the average person something like a Densha de Go! copy and associated controllers will likely suffice, there’s a lot to be said for having something closely resembling the real deal for a realistic game, whether it’s a train, car or airplane controller and associated instrumentation.
