The Most Plausible Apollo Moon Landing Conspiracy Ever Devised

January 6, 2016 by 247 Comments

The Internet is polluted with craziness, and there is no better example than YouTube. If you’ve ever wondered what would happen when you give everyone on the planet the power to show everyone else on the planet their innermost thoughts, desires, and insane ramblings, you need only look at YouTube.

One of the biggest offenders of incoherent ramblings is the subject of spaceflight. Simply search ‘space shuttle’ on YouTube, and you’ll find accusations of the crew of Columbia being abducted by aliens. Crazy, incoherent, and somewhat insulting. Accusations of a moon landing conspiracy are unavoidable in the ‘related videos’ section and are similarly filled with videos from people with either a tenuous grasp of reality or too much time on their hands.

A broken clock is right twice a day, a broken calendar is right every twenty-eight years or so, and every once in a while, simply from the volume of videos on the subject, one conspiracy theorist will present a new and novel idea. Here we present perhaps the only moon landing conspiracy theory that makes sense, is consistent with physical laws, and that may actually be true.

The 3D Printers Of CES

January 6, 2016 by 65 Comments

CES, the Consumer Electronics Show, is in full swing. That means the Hackaday tip line is filled to the brim with uninteresting press releases, and notices that companies from the world over will be at CES.

3D printing has fallen off the radar of people who worship shiny new gadgets of late, and this is simply a function of 3D printing falling into the trough of disillusionment. The hype train of 3D printing is stuck on a siding, people are bored, but this is the time that will shape what 3D printing will become for the next ten years. What fascinating news from the 3D printing industry comes to us from CES?

Hack Your Brain: The McCollough Effect

January 6, 2016 by 81 Comments

There is a fascinating brain reaction known as the McCollough Effect which is like side-loading malicious code through your eyeballs. Although this looks and smells like an optical illusion, the science would argue otherwise. What Celeste McCollough observed in 1965 can be described as a contingent aftereffect although we refer to this as “The McCollough Effect” due to McCollough being the first to recognize this phenomena. It’s something that can’t be unseen… sometimes affecting your vision for months!

I am not suggesting that you experience the McCollough Effect yourself. We’ll look at the phenomena of the McCollough Effect, and it can be understood without subjecting yourself to it. If you must experience the McCollough Effect you do so at your own risk (here it is presented as a video). But read on to understand what is happening before you take the plunge.

BabyBaby: A 1948 Computer On An FPGA

January 6, 2016 by 11 Comments

The Manchester Baby seems simple today. A 32-bit machine with 32 words of storage. It wasn’t meant to be a computer, though, but a test bed for the new Williams tube storage device. However, in 1948, it executed stored programs at about 1,100 instructions per second. The success of the machine led to a series of computers at Manchester University and finally to the first commercially available computer, the Ferranti Mark I.

[Dave] is lucky enough to volunteer to demonstrate the Baby replica at Machester’s Museum of Science Industry. He wanted his own Baby, so he used a Xilinx FPGA board to build a replica Baby named BabyBaby. Although it runs at the same speed as the original, it is–mercifully–much smaller than the real machine.

Android Set Top Box Lets You Stream And Record Via HDMI Input

January 6, 2016 by 30 Comments

While on the hunt for some hardware that would let him stream video throughout his LAN [danman] got a tip to try the €69 Tronsmart Pavo M9 (which he points out is a re-branded Zidoo X9). With some handy Linux terminal work and a few key pieces of software [danman] was able to get this going.

The Android box was able to record video from the HDMI input with pre-installed software found in the main menu as [danman] explains on his blog. File format options are available in the record menu, however none of them were suitable for streaming the video (which was the goal, remember?).

[danman] was able to poke around the system easily since these boxes come factory rooted (or at least the Tronsmart variant that [danman] uses in his demo did). Can anyone with a Zidoo X9 verify access to the root directory?

Long story short, [danman] was able to get the stream working over the network. Although he did have to make some changes to the stream command he was issuing over ssh. He finds the fix in the ffmpeg documentation which saves you the trouble of reading through it but you’ll have to check out his blog post for that (pro tip: he links to a sweet little .apk reverse engineering tool as well).

We’ve seen set top box hacks before, however, streaming and recording HDMI at this price is a rare find. If you’ve been hacking up the same tree let us know in the comments, and don’t forget to send in those tips!

Ten Mile Raspberry Pi WiFi (with A Catch)

January 5, 2016 by 57 Comments

How would you like to have a WiFi connection that covers 10 miles? Or how about an even wider network made up of a mesh of multiple nodes? It is possible, but there is a catch: you probably need a ham radio license to do it (at least, you do in the United States).

What makes it possible is the realization that conventional WiFi channels 1-6 are inside an existing US ham band. That means (if you are a ham) you can elect to use FCC part 97 rules instead of part 15 that governs WiFi routers. That means you can use more power and–even more importantly–better antennas to get greater range.

Traditionally, hams have used custom firmware for Netgear routers or Ubiquiti hardware. However, [WZ0W] recently posted his experience using Raspberry Pi boards as mesh nodes. The code (which also works with some other single board computers) is available on GitHub (with details on the project blog). [WZ0W] points out that, unlike using a consumer router, using a Pi provides a reasonably powerful computer for hosting services as well as hosting the network.

ESP8266 GoPro Remote Adds Buttons, Screen

January 5, 2016 by 11 Comments

Last year we featured a GoPro camera remote by [Robert Stefanowicz] that was built around an ESP8266. [Robert] has been working hard on improving this project, and has just released version 2, which adds a screen and multiple buttons. These additions allow the remote to become a two-way device: you can use it to monitor the status of the GoPro, keeping an eye on things like the battery level and the current video mode.

[Robert] decided to make his own PCB to do this, so it’s also a good intro into the stinky art of PCB etching. He isn’t finished yet, though: he is looking to expand the project further by controlling more features on the camera using the third button on the remote.
