Just because you’re making dinner outdoors doesn’t mean you have to cook like a caveman. The Campfire Range from Sweden’s Primus is a collection of complete camp cook stoves made for the wilderness gourmet. The collection includes 3 different 2-burner gas stoves plus stainless pots & pans, cooking utensils, cutlery, plates & pint glasses.

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!

PINE64 Computer
A fifteen dollar computer might seem suspect until you see what’s inside—which you can, with the see-through PINE64, a powerful 64-bit expandable single board computer. Currently available for pre-order on Kickstarter, this little unit packs a 1.2 Ghz Quad-Core Processor, supports up to 2 Gigs of RAM & can output 4K video.

[Voltagex] was fed up with BSODs on his Windows machine due to a buggy PL2303 USB/serial device driver. The Linux PL2303 driver worked just fine, though. A weakling would simply reboot into Linux. Instead, [Voltagex] went for the obvious workaround: create a tiny Linux distro in a virtual machine, route the USB device over to the VM where the drivers work, and then Netcat the result back to Windows.
OK, not really obvious, but a cool hack. Using Buildroot, a Linux system cross-compilation tool, he got the size of the VM down to a 32Mb memory footprint which runs comfortably on even a small laptop. And everything you need to replicate the VM is posted up on Github.
Is this a ridiculous workaround? Yes indeed. But when you’ve got a string of tools like that, or you just want an excuse to learn them, why not? And who can pass up a novel use for Netcat?

Creators of 3Dponics indoor gardening system to launch Cloud-based 3D modeling app 3Dcreative.ly
Ask any hobbyist 3D printer without previous CAD experience what one of their biggest hurdles in creating new objects is and it’s likely to involve 3D modeling. While existing CAD programs including SolidWorks and Rhino offer professional-level CAD tools designed for creating real-world products, they can easily cost over $1,000 and even up to $10,000 depending on add-ons and other features.

Laser-Etch Stainless with Only Plaster & Alcohol
Many hobbyists and hackerspaces have the $500 Chinese 40W lasercutters which most of us know are about as successful at etching metals as a featherduster is at drilling. [Frankie] and [Bryan] have figured out a way to use the laser to chemically activate an etching process. See experiment part 2 as well.
First, to be clear, they are using a quality 40W Epilog Zing, not the cheap one, but40W is40W. They mixed the plaster (calcium sulfate) with Isopropyl until it resembled white ketchup. After either thinly painting or airbrushing the material onto the stainless surface (both worked), the mixture is dried with a heatgun then put into the laser. 100% power and 5% speed was what worked for them.
The result was an engrave with a noticeable bite. Something they claim had no effect at all without the mixture.
Stainless steel is an alloy of iron and some chromium – not the same as chrome-plated steel. [Frankie]’s explanation of the chemistry is that the surface layer of the stainless is a transparent chromium oxide. With the heat of the laser, the calcium and chromium swap dance partners. Calcium takes the oxygen and chromium takes the sulfate. The calcium oxide washes off but the chromium sulfate causes the etch.
Next time you’re at your local space, give this a try.

Husband and wife create superfood ‘3D printer’ to get their kids to eat their vegetables
A new Israeli startup wants to change all of that (for their kids) and not just with regular food, but superfood. Partly inspired by additive manufacturing, Tsipi and Ben Shoham, founders of Green Onyx, want bridge the gap between agriculture and 3D printing in a way that makes eating vegetables fun for kids (and adults).

A Simple Hoverboard Everyone Can Understand
To be honest, we were wondering when we would see someone try this…
[Ryan Craven] has successfully built a working hovercraft that looks like a skateboard. It floats on two pockets of air generated by four Black and Decker leaf blowers — and by golly, it certainly looks like it works!
Ever since the HUVr hoax earlier this year, [Ryan] has had the goal to make a real, working hoverboard. Hendo may have beaten him to the punch with their $10,000 eddy current inducing halbach array board, but alas, it only works on copper or aluminum floors. [Ryan’s] can be used anywhere a normal skateboard can be. It’s far from sleek, but it’s only just the prototype — though we’re curious to see how far this could actually go.
Which is precisely why he’s shared it over on Hackaday.io and is hoping to draw some support and ideas from our wonderful community here.
What do you guys think? Is it worth continuing the pursuit of a hovercraft style hoverboard? Can we shrink the technology enough to make it feasible? It’s come a long way from the classic hover craft using a giant shop vac…
