This week, Popular Mechanics published cutaway diagrams of ships that will be seen in Star Trek: Beyond, released later this month. This is your cue for spoilers for the remainder of this paragraph. The USS Franklin looks suspiciously like – and was likely built after – the NX-01, the titular ship of Star Trek: Enterprise. The Abrams-verse Franklin was the first Warp 4 ship, yet the prime universe NX-01 was the first Warp 5 ship, with previous ships having trouble reaching Warp 2. We must now consider the Abrams-verse Trek is not a parallel universe to prime-universe Trek and should therefore be considered a completely separate canon (yes, even the destruction of Vulcan. If you see the new Star Trek movie, the NX-01 launched in 2151, and your suggested viewing beforehand is ST:ENT, S02E24, First Flight.

The Mechaduino is a Hackaday Prize entry that turns steppers into closed-loop servos. It’s a phenomenal idea, and now it’s a Kickstarter.

Walk into a dollar store, and you’ll find stupid solar powered electronic flower pots. They’re bits of plastic that shake a plastic flower back and forth when placed in the sun. They’re selling millions, and I have no idea why. [Scott] put a jolly wrencher on one of these flower pots. Really, this is just an exercise in 3D printing, but [Scott] printed the jolly wrencher. We don’t see a lot of that, due to how difficult it is to render the wrencher in OpenSCAD.

In just a few hours, Juno will perform an insertion burn around Jupiter. Does this mean pretty pictures? Not quite yet. This is the closest a spacecraft has ever gotten to Jupiter, and over thirty or forty orbits, Juno will fly between Jupiter’s massive radiation belts. Here’s the NASA trailer.

This video recently caught the Internet’s attention. It’s squares and circles that when put next to a mirror look like circles and squares. Yes, it’s weird. People have 3D printers, so of course these ambiguous objects were quickly reverse engineered and printed. Here’s how they work

It looks like Brexit has caught up to Mouser. Here’s their country select dialog for eu.mouser.com. Thanks [Tom] for the screencap.

The Navy is doing some crazy stuff out in China Lake. They were planning to test something out that could potentially make GPS unusable from San Diego to Las Vegas to San Francisco. Those plans were cancelled for ‘internal’ reasons. They will be testing something in Indiana shortly, though. What are they doing? Who knows. That’s what idle speculation in the comments section is for.

3D Hubs, the distributed ‘3D printing service’ thing, now has 30,000 machines distributed around the globe. They also put together the definitive guide to 3D printing recently. For just about everyone reading this, a ‘introduction to 3D printing’ is old news, but this is a very good guide for telling your weird aunt what you’re building in the basement. Forward this one to your family on Facebook.

This one is amazing. Over on Hackaday.io, [Arsenijs] is working on a Raspberry Pi project. It uses a Raspberry Pi, and several accessories and components to make this Raspberry Pi project work. This Raspberry Pi project is already getting far more than the usual number of likes and follows, making this one of the most interesting Raspberry Pi projects in recent memory.

Moog is re-releasing the Minimoog, the original Moog synth from 1970. That’s cool, but what about a DIY Minimoog? That’s what [Scott Rider] is doing with the Crowminius Analog Music Synthesizer on Kickstarter. It’s an analog synth that’s more or less a Minimoog with MIDI, and one of the Kickstarter rewards is a bare PCB.

The future is dancing robots, so here’s a servo-driven Stewart platform that is sure to bring on the robot apocalypse.

What do you do when you need to get your Hackaday fix, but all you have is a laptop from 1995 and a dial-up modem? The Hackaday Retro Edition, of course. That’s a bunch of retro Hackaday posts, posted five at a time, with all the CSS and JavaScript cruft stripped. We’re always interested to see the old machines that are pulling the retro edition down, and [djnikochan] has the latest entry. He found a Thinkpad 380ED from 1997 at the Goodwill store for $15. The RAM was upgraded with a 64MB SIMM, giving this machine a total of 80MB. The Hackaday Retro Edition is viewable with IE 5.5 over a trusty PCMICA WiFi card. Awesome job, and we love to see old iron rendering the retro edition. Send some pics in if you get your old battlestation to load it.

How Did Pocket NC Survive and Thrive?

We had a chance to talk to Matthew Hertel of PocketNC at the Bay Area Maker Faire this year. During the conversation, he answered some questions I’d had about the project since I saw it on Kickstarter, and told a cool story while he was at it.

When the Pocket NC 5-axis Tabletop CNC Mill KickStarter came out, I immediately chocked it up as a failure out of the gate. I figured that there would never be a single delivered unit. It just seemed too impossible. The price was too low for a machine with that many large machined aluminum pieces. It had real linear guides. It had a real spindle and housed a beagle bone black running linuxCNC. It just couldn’t be that cheap. Ends up, I’m quite happy to be wrong. Pocket NC is doing well, delivering their first units, and taking new orders.

The CNC equivalent of a brag track on a hip-hop record.

It’s easy to get jaded with the Kickstarter and IndieGoGo scams that are out there. Or even the disappointing behavior of projects that could be legitimate. People often do failure analysis of companies, but it is also worth investigating what people did right when they are successful.

Lulzbot’s TAZ 6 has been released. Lulzbot’s printers consistently place in the top three of any 3D printing list, and the TAZ 6 will likely be no exception. [James Bruton] was one of the lucky ones who got a review unit, and first looks are promising. The TAZ 6 has the auto bed leveling found in the Lulzbot Mini, and a ‘power tower’ for all the electronics. There are completely unconfirmed rumors (or someone told me and I forgot who) that the power tower will be available separately at some point.

The most impressive circuit we’ve seen this week month year is the dis-integrated 6502. It’s a discrete 6502 CPU, about a square foot in size. It’s slow, but it works. RAM and ROM is easy to make embiggened, which means someone needs to build a dis-integrated 6522 VIA. Who’s game?

[Jeremy Cook] wanted to learn another CAD package, in this case Onshape. Onshape is the ‘first cloud-only CAD package’, which has one huge bonus – you can run it anywhere, on anything – and one huge minus – it’s in the cloud. He designed a bicycle cupholder.

Last week, several thousand Raspberry Pi Zeros shipped out to retailers in the US and UK. For a time, Pi Zeros were in stock in some online stores. Now? Not so much. Where did they all go? eBay, apparently. It’s called arbitrage, and it’s the only risk-free form of investment.

Remember those ‘bed of nails’ toys, that were basically two sheets of plastic, with hundreds of small pins able to make 3D impressions of your face and hands. No, there is no official name for these devices, but here’s a Kickstarter for a very clever application of these toys. You can use them to hold through hole parts while soldering. Brilliant.

You should not pay attention to 3D printers on Kickstarter. Repeat after me: you should not give money to 3D printers on Kickstarter. Here’s a 3D printer on Kickstarter, promising a 3D printer for $74. I own several hats, and will eat one if this ships by next year.

Remember bash.org? It’s being reimplemented on hackaday.io.

Why Kickstarter Products Fail

It seems every week we report on Kickstarter campaigns that fail in extraordinary fashion. And yet there are templates for their failure; stories that are told and retold. These stereotypical faceplants can be avoided. And they are of course not limited to Kickstarter, but apply to all Crowd Funding platforms. Let me list the many failure modes of crowdfunding a product. Learn from these tropes and maybe we can break out of this cycle of despair.

Failure Out of the Gate

You don’t hear about these failures, and that’s the point. These are crowd funded projects that launch into the abyss and don’t get any wings through printed word or exposure. They may have a stellar product, an impressive engineering team, and a 100% likelihood of being able to deliver, but the project doesn’t get noticed and it dies. Coolest Cooler, the project that raised $13 million, failed miserably the first time they ran a campaign. It was the second attempt that got traction.

The solution is to have a mailing list of interested people are ready to purchase the moment you launch, and share to everyone they know. Reach out to blogs and news organizations a month early with a press package and a pitch catered to their specific audience. Press releases get tossed. Have a good reason why this thing is relevant to their audience. Offer an exclusive to a big news site that is your target market.

Peachy Printer Collapses, Investor Built A House Instead Of A Printer

The Peachy Printer, originally a crowdfunding campaign for a $100 stereolithography 3D printer, is now dead in the water.[Rylan Grayston], the creator of the Peachy Printer, announced that [David Boe] — investor, 50% owner of Peachy Printer, and business partner — had stolen over $300,000 in Kickstarter campaign funds. According to [Rylan], this money was used to build a house.

When the Peachy Printer was announced on Kickstarter, it was, by any measure, a game changing product. Unlike other stereolithographic printers like the Form 1 and DLP projector kit printers, the Peachy was cheap. It was also absurdly clever. Instead of using a stepper motor to raise a print out of a vat of resin, the Peachy Printer floated the resin on a vat of salt water. By slowly dripping salt water into this vat, the level of the resin rose up, allowing the galvanometers and laser diode to print the next layer of a 3D object. In our first coverage of the Peachy Printer, everyone was agog at how simple this printer was. It wasn’t a high-resolution printer, but it was a 3D resin printer that only cost $100. Even today, nearly three years after the launch of the Kickstarter campaign, there’s nothing like it on the market.

For the last two years, [Rylan] appeared to have the Peachy Printer in a pseudo-stealth mode. Whispers of the Peachy Printer circled around 3D printer forums, with very little information coming from [Rylan]. For the last year, the Peachy Printer appeared to be just another failed crowdfunded 3D printer. Either [Rylan] didn’t have the engineering chops to take a novel device to market, there were problems with suppliers, or [Rylan] just couldn’t get the product out the door.

In the update published to the Kickstarter campaign, the reason for the failure of Peachy Printer to deliver becomes apparent. The Kickstarter campaign was set up to deliver the funds received – $587,435.73 – directly into [David Boe]’s account. Thirty days after the funds were received, [David] had spent over $165,000. In just over three months, all the Kickstarter funds, save for $200,000 transferred into the Peachy Printer corporate account, were spent by [David].

With no funds to complete the development of the Peachy Printer, [Rylan] looked into alternative means of keeping the company afloat until Kickstarter rewards had shipped. Peachy Printer received two government grants totalling $90,000 and $135,000. In March of 2015, one of [Rylan]’s family members loaned $50,000 to Peachy Printer. A plan to finance the delivery of Kickstarter rewards with new sales – a plan that is usually looked down upon by Kickstarter backers – was impossible, as cost and time required of certifying the laser in the Peachy Printer would have put the company in the red.

Right now, [Rylan] and the Peachy Printer are pursuing repayment from [David Boe], on the basis that Kickstarter reward money is still tied up in the construction of a house. Once the house is complete, the bank will disburse funds from the construction mortgage, and funds can then be transferred from [David] to Peachy Printer.

In all, the Peachy Printer is a mess, and has been since the Kickstarter funds were disbursed to [David]. There is – potentially – a way out of this situation that gets Peachy Printers into the hands of all the Kickstarter backers if the mortgage construction funds come through and production resumes, but that’s a lot of ‘ifs’. Failed Kickstarter projects for 3D printers are nothing new, but [Rylan]’s experience with the Peachy Printer is by far the most well-documented failure of a crowdfunding project we’ve ever seen.

TruckThe Internet Archive has a truck. Why? Because you should never underestimate the bandwidth of a truck filled with old manuals, books, audio recordings, films, and everything else the Internet Archive digitizes and hosts online. This truck also looks really, really badass. A good thing, too, because it was recently stolen. [Jason Scott] got the word out on Twitter and eagle-eyed spotters saw it driving to Bakersfield. The truck of awesome was recovered, and all is right with the world. The lesson we learned from all of this? Steal normal cars. Wait. Don’t steal cars, but if you do, steal normal cars.

In a completely unrelated note, does anyone know where to get a 99-01 Chevy Astro / GMC Safari cargo van with AWD, preferably with minimal rust?

[Star Simpson] is almost famous around these parts. She’s responsible for the TacoCopter among other such interesting endeavours. Now she’s working on a classic. [Forrest Mims]’ circuits, making the notebook version real. These Circuit Classics take the circuits found in [Forrest Mims]’ series of notebook workbooks, print them on FR4, and add a real, solderable implementation alongside.

Everyone needs more cheap Linux ARM boards, so here’s the Robin Core. It’s $15, has WiFi, and does 720p encoding. Weird, huh? It’s the same chip from an IP webcam. Oooohhhh. Now it makes sense.

Adafruit has some mechanical keyboard dorks on staff. [ladyada] famously uses a Dell AT101 with Alps Bigfoot switches, but she and [Collin Cunningham] spent three-quarters of an hour dorking out on mechanical keyboards. A music video was the result. Included in the video: vintage Alps on a NeXT keyboard and an Optimus Mini Three OLED keyboard.

A new Raspberry Pi! Get overenthusiastic hype! The Raspberry Pi Model A+ got an upgrade recently. It now has 512MB of RAM

We saw this delta 3D printer a month ago at the Midwest RepRap festival in Indiana. Now it’s a Kickstarter. Very big, and fairly cheap.

The Rigol DS1054Zed is one of the best oscilloscopes you can buy for the price. It’s also sort of loud. Here’s how you replace the fan to make it quieter.

Here’s some Crowdfunding drama for you. This project aims to bring the Commodore 64 back, in both a ‘home computer’ format and a portable gaming console. It’s not an FPGA implementation – it’s an ARM single board computer that also has support for, “multiple SIDs for stereo sound (6581 or 8580).” God only knows where they’re sourcing them from. Some tech journos complained that it’s, “just a Raspberry Pi running an emulator,” which it is not – apparently it’s a custom ARM board with a few sockets for SIDs, carts, and disk drives. I’ll be watching this one with interest.
