Are you a student? Are you part of a hackerspace? We have a contest going on right now where you can win a fancy new Prusa i3 MK3. The Repairs You Can Print contest is a challenge to do something useful with that machine that spits out tugboats. We’re looking for functional repairs of items around your house, office, or garage. Did you repair something with a 3D printer? Then you too can get in on the action! Enter now! Check out the entries!
You may know Flite Test as the group who do everything surrounding remote control flight (mostly fixed wings, a nice counter to the quadification of the hobby over the last few years). Flite Test designs and sells airplanes made out of Dollar Tree foam board, they have yearly, bi-coastal meetups, and they’re all-around awesome dudes. Now, they want to build the Disneyland of RC flight. [Josh Bixler], the face of Flite Test and a guy who has a plane named after him, wants to buy a golf course and turn it into the world’s best RC flying park, with a ~2000 foot grass strip for general aviation. We’re looking at their crowdfunding campaign, and it looks promising it might be funded by the time this goes live.
A while ago, [Peter Jansen], the guy who built a tricorder and a laser-cut CT scanner, made a magnetic camera. This Hall Effect camera is a camera for magnetism instead of light. Now, this camera has been fully built and vastly improved. He’s capturing ‘frames’ of magnetism in a spinning fan at 2000 Hz (or FPS, terminology kind of breaks down here), and it’s beautiful.
Oh thank God we can finally buy GPUs again. Try buying them with Bitcoin.
In the last few years, CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, has expanded. Originally, this was one of the treaties that banned the import or export of rhino horn, but recently this expanded to the export of rosewood thanks to increased demand in China for rosewood furniture. The laws of unintended consequences kicked into effect, and importing anything made out of rosewood is now a mess of permits and inspections at the border, including musical instruments. Travelling orchestras, for example, are at risk of having their string section confiscated because of rosewood tuning pegs. Cooler minds may now be prevailing, and there’s some hope the regulations may be changed during the next meeting of the CITES convention next year.
As noted a few months ago, there was a possibility of Broadcom buying Qualcomm for one… hundred… Billion dollars. This offer was rejected, with Qualcomm saying the offer wasn’t high enough. Broadcom fired back with an offer of $82 per share, or $121B. This offer was rejected this week.
Need some EMC testing? [Zach]’s got your back. He’s reserved some time in a 10m EMC chamber for testing NeuroBytes this week. If you have an Open Source project that needs a pre-test scan for unintentional radiator, you can get in on the action. This is just a pre-test, you’re not getting certification, and you’re not going to test anything with radios, and you need to ship [Zach] your stuff. But still, free test time. Woo.

The resolution looks pretty low though.
Magnetic field viewing film with a CCD pointed at it would be far better, and cheaper, just use a RPi HD camera and a 3D printed enclosure. Do a bit of maths with OpenCV to get colours and or vectors too. Spin your film so it is like a shutter and you can have your magnetic field image as an overlay on the normal video image, but that makes the device 4 times bigger in two dimensions.
But nowhere near as sensitive…
well he’s only got a 64 bit grid and lots of space between sensors. It’s a prototype. The first cmos cameras sucked pretty hard compared to today’s. Al it would take to increase resolution is an integrated chip with an array of sensors on it…can you hear me TI??
pls donate your elegiggles, he worked very jard to make thatbitcoin joke funny
“Try buying them with Bitcoin.” — It’s entirely possible to do that. You can buy whole computers with them, if you feel like it, so this seems like a stupid thing to say.
Benchoff is just ever so slightly salty he didn’t get in on Bitcoin back in 2011 (https://hackaday.com/2011/08/22/fpga-bitcoin-miner-is-probably-the-most-power-efficient/).
I don’t think anyone doubts that it’s possible to buy computer hardware with BTC. It’s more of a statement about the instability of the currency and reluctance of mainstream retailers to support it.
Newegg is pretty mainstream.
I bought stuff on the HaD store with it.
Someone salty because they lost half their net worth in two months?
Nah, just kidding. I invented bitcoin.
i was thinking, giving a 3D printer to people with a 3D printer is really current, since it’s similar to giving money to the people who have lots of money. :)
But it is being given to an “organization”, i.e. school, makerspace, and they will use an additional 3D printer, certainly it will make printing available to more of their members.
It’s trickling down you mean?
I wasn’t happy to read that either,
but I didn’t make the rule.
I’m fine with it all and understand it’s good for hackerspaces to have stuff, I just find a setup ripe for some jokes.
I not have lots of money, but am student and no 3D printers or hackerspaces. Possibly may I enter? Is this only for the Americas with money for 3D printer already?
Hi Wuan,
This contest does require that you show a 3D printed repair to enter. But keep your eyes open, there are more contests coming up soon that will be possible for you to enter if you don’t currently have access to a 3D Printer.
We thought the same thing, that’s why the 3D Printers as prizes are reserved for those we think would need a better 3D Printer: Students and Organizations.
A lot of students begin 3D printing by using a printer at a local hackerspace, at their school, or at a library. We want to get a great printer into the hands of a motivated hacker since it will find the most use with that person.
I think my area is more common than large citys with hackerspace and schools. I think areas outside these places are equal or more motivated. Although these places can show their projects more to generate the content.
