Sonic 3D Printer Auto Bed Leveling Makes A Swoosh

July 18, 2016 by Moritz Walter 49 Comments

3D Printering: the final frontier. These are the voyages of another 3D printer hack. Its mission: to explore strange new ways of leveling a print bed.

So far, we’ve had servo probes, Allen key probes, Z-sled probes, inductive and capacitive contactless switches, just to name a few. All of them allow a 3D printer to probe its print bed, calculate a correction plane or mesh, and compensate for its own inherent, time variant, inaccuracies.

Russian Decapping Madness

July 18, 2016 by Elliot Williams 37 Comments

It all started off innocently enough. [mretro] was curious about what was inside a sealed metal box, took a hacksaw to it and posted photographs up on the Interwebs. Over one hundred forum pages and several years later, the thread called (at least in Google Translate) “dissecting room” continues to amaze.

If you like die shots, decaps, or teardowns of oddball Russian parts, this is like drinking from a firehose. You can of course translate the website, but it’s more fun to open it up in Russian and have a guess at what everything is before peeking. (Hint: don’t look at the part numbers. NE555 is apparently “NE555” in Russian.)

From a brief survey, a lot of these seem to be radio parts, and a lot of it is retro or obsolete. Forum user [lalka] seems to have opened up one of every possible Russian oscillator circuit. The website loads unfortunately slowly, at least where we are, but bear in mind that it’s got a lot of images. And if your fingers tire of clicking, note that the URL ends with the forum page number. It’d be a snap to web-scrape the whole darn thing overnight.

We love teardowns and chip shots, of old gear and of new. So when you think you’ve got a fake part, or if you need to gain access to stuff under that epoxy blob for whatever reason, no matter how embarrassing, bring along a camera and let us know!

Thanks [cfavreau] for the great tip!

Video Games In As Few Dimensions As Possible

July 17, 2016 by Elliot Williams 34 Comments

First there were text games, then came 2D dungeons. When Wolfenstein 3D broke out on the gaming scene, it created quite a fuss. But if all you’ve got is a strip of WS2812 LEDs, those are a few dimensions too many.

[treibair] has started up a project on Hackaday.io to develop 1D video games to be played on a single LED strip. While the end application is something with a cool physical interface, probably driven by a microcontroller, prototyping is a lot easier on the big computer. He’s writing it in Processing, though, so that the transition to the Arduino is easier in the end.

There are a couple of other games out there in 1D, including Line Wobbler (YouTube) and, naturally, Wolfenstein 1D. We even saw a one-dimensional “snake” clone at Make Munich a few months back. (Would the author please stand up?)

We think the idea is a good one, and lining up everyone’s 1D gaming experience in one place would be a great help. So link up code and reviews in the comments!

Pokédex Case Keeps Your Phone Powered Up So You Can Catch ‘Em All

July 16, 2016 by James Hobson 17 Comments

The launch of Pokemon Go has unleashed the franchise upon the world once again but this time it’s encouraging users to get active and socialize in the great outdoors. To show off their dedication to the cause, [Npoole] 3D printed a Pokédex external battery and case to combat the game’s already legendary drain on their Galaxy S4’s resources.

Mimicking the first-generation Kanto design, [Npoole] 3D printed it in red ABS and added a small circuit with a red, yellow and green LED to complete the effect. Inside, a 18650 lithium cell provides the much-needed backup power via a micro B plug and is boosted to 5V with a LiPo charger/booster board. Despite a switch on the circuit, the battery slowly drains so that’s something to be corrected in a future version.

As you can see, there is still some room left over in the external bat–I mean–Pokédex, and [Npoole] intends to add another battery and a cooling fan to further improve the design. The result is a little bulky, but for new and diehard fans alike, a working Pokédex definitely worth it.

While that’s printing, if you’re looking to hack your way to the perfect Poké-ball throw, try out this lo-tech addition to your Pokémon trainer kit.

Tearing Apart The Nintendo PlayStation

July 16, 2016 by Brian Benchoff 30 Comments

The mid 90s were a weird time for video game hardware. There were devices that could play videos from compact disks. Those never caught on. Virtual reality was the next big thing. That never caught on. The Sony PlayStation was originally an add-on for the Super Nintendo. That never caught on, but a few prototype units were produced. One of these prototype ‘Nintendo Playstations’ was shipped to a company that went into bankruptcy. Eventually, the assets of this company were put up for auction, and this unbelievably rare game console was bought by [Terry Diebold] for $75.

[Terry] allowed [Ben Heck] tear into this piece of videogame history, and he has the video proof that this was a collaboration between Sony and Nintendo.

Your ESP8266 Needs More Memory

July 16, 2016 by Elliot Williams 44 Comments

We just got through reviewing MicroPython on the ESP8266, and one of the main takehomes is that our ESP modules need more flash memory. You may be in the same boat — the earliest (and cheapest) modules on the market only had 512 kB of flash. For over-the-air programming, or to give you some more space for fancier programs, you’re going to want 1 MB or even 4 MB.

The solution? Just buy a new flash chip and solder it on. This is especially easy if you’ve got an ESP-01, ESP-03, or ESP-11 modules where the flash chip is exposed. Desolder, resolder, done. It can be a little trickier for those modules with a tin can around chips, but that’s nothing that a little hot air can’t fix. See the video embedded below for a good walk-through.

Obsolescence As A Service

July 16, 2016 by Elliot Williams 70 Comments

Yet another Internet of Things service has left its customers in the lurch. IoT devices (mostly lightbulbs) ~~made~~ sold by Greenwave Systems stopped talking to the outside world on July 1. More specifically, the server to which they all connected (ahem, “the cloud”) has been turned off, which rules out using the bulbs with Internet-based services like IFTTT, which was a major selling point of the Things in the first place.

[Edit: We were contacted by Greenwave, and they pointed out that they merely sold the IoT devices in question. They are made by TCP, which is also responsible for cancelling the service. And TCP has a history of doing this sort of thing before.]

It’s not the first time we’ve seen IoT companies renege on their promises to provide service, and it’s surely not going to be the last. We’re preaching to the choir here, but when even Google is willing to take the PR hit to effectively brick your devices, the only protection that you’ve got against obsolescence is an open protocol.

At least the users of ~~Greenwave’s~~ TCP’s devices will continue to be able to control them from within the home. That, plus some clever hacking, will make them workable into the future. But it’s not like the convenience that was sold with the devices.

Boo to shady IoT companies! But thanks to [Adrian] for the tip.
