Veteran SpaceX Booster Lost Due To Rough Seas

December 27, 2023 by Tom Nardi 44 Comments

With the notable exception of the now retired Space Shuttle orbiters, essentially every object humanity ever shot into space has been single-use only. But since December of 2015, SpaceX has been landing and refurbishing their Falcon 9 boosters, with the end goal of operating their rockets more like cargo aircraft. Today, while it might go unnoticed to those who aren’t closely following the space industry, the bulk of the company’s launches are performed with boosters that have already completed multiple flights.

This reuse campaign has been so successful these last few years that the recent announcement the company had lost B1058 (Nitter) came as quite a surprise. The 41 meter (134 foot) tall booster had just completed its 19th flight on December 23rd, and had made what appeared to be a perfect landing on the drone ship Just Read the Instructions. But sometime after the live stream ended, SpaceX says high winds and powerful waves caused the booster to topple over.

Hackaday Podcast Episode 249: Data By Laser And Parachute, Bluetooth Hacks, Google’s Gotta Google

December 22, 2023 by Tom Nardi 6 Comments

‘Twas the podcast before Christmas, and all through the house, the best hacks of the week are dancing around Elliot and Tom’s heads like sugar-plums. Whatever that means.

I’d just like to interject for a moment. What you’re referring to as Christmas is, in fact, Happy/Holidays.

Before settling their brains in for a long winter’s nap, they’ll talk about the open source software podcast that now calls Hackaday home, the latest firmware developments for Google’s Stadia controller, high-definition cat videos from space, and upgrades for the surprisingly old-school battery tech that powers the Toyota Prius.

Out on the lawn, expect a clatter about the the state-of-the-art in DIY camera technology, the acoustic properties of hot chocolate, and a storage media from the 1990s that even Al Williams had never heard of.

Finally, after tearing open the shutters and throwing up the sash, the episode wraps up with a discussion about wiring techniques that let you leave the soldering iron at home, and the newest chapter in the long history of transferring data via parachute. Miniature sleigh and eight tiny reindeer sold separately.

Download the gift you really want this year: this week’s podcast in DRM-free MP3.

Raspberry Pi Zero Powers Custom Camera Platform

December 19, 2023 by Tom Nardi 7 Comments

These days, most of us are carrying a fairly impressive digital camera with us at all times. But as capable as the hardware and software of a modern smartphone may be, there’s still plenty of reasons you may want a “real” camera to go along with it. The larger sensor, advanced controls, and selection of lenses that you’ll get with even a relatively cheap camera opens up a world of artistic possibilities.

If you’re really into chasing that perfect shot, you can even build your own digital camera these days. This design from [Jacob Cunningham] may not be able to go shot-for-shot against a Canon or Nikon in its current state, but we think you’ll agree there’s a lot of potential here — especially for something pieced together with modular components and perfboard.

Inside the 3D printed enclosure is a Raspberry Pi Zero, a Pi HQ Camera module, an 1.5″ OLED display, a lithium-ion battery pouch cell, and the charging and voltage regulation boards necessary to keep everything powered up. There’s also a handful of tactile buttons to work through the settings and menus, and a 10-axis IMU to help you keep your horizon level.

[Jacob] figures the whole thing comes in at around at $185.00, though naturally that number could go up or down considerably depending on what you’ve already got in the parts bin and what kind of lenses you add to the mix.

The hardware side of things looks more or less complete, at least for a first version, and [Jacob] has provided everything you’ll need to build one of your own. But the software is still a work in progress, with the latest push to the Python code in the project’s GitHub repository just eight hours old at the time of this writing. If you’ve been looking for a DIY camera project to really sink your teeth into, this could provide a great starting point.

If you’re more interested in moving pictures, we recently covered the CinePi project, which aims to develop an open source cinema-quality camera that you won’t need studio backing to afford.

Disposable Vape Batteries Turned USB Power Bank

December 14, 2023 by Tom Nardi 31 Comments

It’s another one of those fun quirks about our increasingly cyberpunk world — instead of cigarette butts littering our streets, you’re more likely to find disposable vaporizers that have run out of juice. Unfortunately, while the relatively harmless paper remnants of a cig would eventually just fall apart when exposed to the elements, these futuristic caltrops are not only potentially explosive thanks to their internal lithium-ion battery but aren’t going anywhere without some human intervention.

So do the environment and your parts bin a favor: pick them up and salvage their internal cells. As [N-Ender_3] shows with this build, it’s cheap and easy to turn the remnants of a few vapes into a useful USB power bank. In this case, the enclosure is 3D printed, which makes it particularly form-fitting, but you could just as easily pack the cells into something else if you’re not a fan of extruded plastic.

NASA Blames Probe Chute Failure On Wire Labels

December 12, 2023 by Tom Nardi 38 Comments

When NASA’s OSIRIS-REx sample return capsule screamed its way through the upper atmosphere, it marked the first time the space agency had brought material from an asteroid back to Earth. Hundreds of thousands tuned into the September 24th live stream so they could watch the capsule land at the Utah Test and Training Range. But about ten minutes before the capsule was set to touchdown, keen eyed viewers may have noticed something a bit odd — when ground control called out that the vehicle’s drogue parachute was commanded to deploy…nothing seemed to happen.

Now NASA knows why it didn’t work as expected, and it ended up being the sort of Earthly problem that we’d wager a few in this audience have run into themselves from time to time.

Cheap Computer PSU Puts On Weight With Box Of Iron

December 12, 2023 by Tom Nardi 42 Comments

Humans are funny creatures. For whatever reason, when handling a piece of electronics, we tend to equate heft with value. If something feels too light, it gives the impression of being cheap or inferior. As such, it’s not unheard of for gadgets to include a little chunk of metal that serves no purpose other than to add weight.

But a recent discovery by the aptly named [RedditCringe990] really takes things to a new low. Upon opening up the cheap power supply that came with their computer case, they noticed an odd little box that didn’t appear to have any electrical connection to the rest of the device. After unscrewing it from the metal body of the power supply and pulling the bottom panel off, they found it was packed full of iron filings.

At some level, you have to appreciate the attention to detail here. At first glance, especially if you were peeking through the PSU’s air vents, you could be forgiven for thinking the box was some kind of transformer. It’s even got some alphanumeric gibberish written on the side to help complete the look. Makes us wonder how many of these things might actually have gone undetected by less curious PC-builders.

As you might expect, the weighted box is only one of the issues with this particular PSU. As pointed out by fellow Redditor [Hattix], even the functional components are worthy of suspicion. There’s no protection on the input or output, no safety capacitor, and (unsurprisingly) no regulatory marks.

We’d say the thing might still be useful as a boat anchor, but now that the box of iron fillings has been removed, it’s probably not even heavy enough. Stay safe out there, folks.

Artemis’ Next Giant Leap: Orbital Refueling

December 7, 2023 by Tom Nardi 32 Comments

By the end of the decade, NASA’s Artemis program hopes to have placed boots back on the Moon for the first time since 1972. But not for the quick sightseeing jaunts of the Apollo era — the space agency wants to send regular missions made up of international crews down to the lunar surface, where they’ll eventually have permanent living and working facilities.

The goal is to turn the Moon into a scientific outpost, and that requires a payload delivery infrastructure far more capable than the Apollo Lunar Module (LM). NASA asked their commercial partners to design crewed lunar landers that could deliver tens of tons of to the lunar surface, with SpaceX and Blue Origin ultimately being awarded contracts to build and demonstrate their vehicles over the next several years.

Starship and Blue Moon, note scale of astronauts

At a glance, the two landers would appear to have very little in common. The SpaceX Starship is a sleek, towering rocket that looks like something from a 1950s science fiction film; while the Blue Moon lander utilizes a more conventional design that’s reminiscent of a modernized Apollo LM. The dichotomy is intentional. NASA believes there’s a built-in level of operational redundancy provided by the companies using two very different approaches to solve the same goal. Should one of the landers be delayed or found deficient in some way, the other company’s parallel work would be unaffected.

But despite their differences, both landers do utilize one common technology, and it’s a pretty big one. So big, in fact, that neither lander will be able to touch the Moon until it can be perfected. What’s worse is that, to date, it’s an almost entirely unproven technology that’s never been demonstrated at anywhere near the scale required.
