We made a point to stop by the Freescale booth at Maker Faire where [Bunnie Huang] was showing off the Novena laptop. His past accolades (Wikipedia page) and the rabid success of the crowd funding round — which nearly tripled its goal — meant we had to make multiple attempts to speak with him. But the third time’s a charm and it was worth the wait!

Several things struck me about seeing the hardware in person. First off, I like that there’s a little bit of room inside but the case is still reasonably small. This really is a laptop aimed at hardware hacking; I would anticipate that the majority of backers intend to roll their own hardware for it. Second, [Bunnie] showed off several expansion boards as examples which use a standard 80-pin header to get at the onboard components. The example of a man-in-the-middle attack for the flash chip on a thumb drive was extremely tasty. But it was also interesting to hear about an SDR board which will ship to original backers since the campaign made its stretch goals.

If you don’t know much about this project, you can get some background from our post when the crowd funding went live. Open design info is available from the Novena page.

Mini-Molder: Blow Molder Scratch-Built By Single Hacker

We caught up with [James Durand] at Maker Faire. He was one of the rare Makers (no mention of selling or future crowd funding) that had a booth at Maker Faire — he was exhibiting a blow molding machine that he built from scratch.

The fabrication process is 100% [James]. Every custom part was designed and milled by him. All of the assembly techniques were his to learn along the way. And we didn’t see anything that isn’t production ready. We’re both impressed and envious.

About three years ago he got the itch to build the mini-molder after learning about the Mold-A-Rama machine — a blow-molding vending machine that was popular a half century ago. A bit of his journey is documented as a molding category on his blog. For the most part it sounds like 1.5 years spent on the CAD design really paid off. He did share one element that required redesign. The initial prototype had a problem with the molds being pushed up when they came together. He tweaked the mechanism to close with a downward motion by flipping the hinge design. This seems to hold everything in place while the drinking fountain chiller and water pump cool the mold and the plastic model within.

Live Look At Taktia Augmented Power Tool And Carbide 3D Mill

May 21, 2014 by Mike Szczys 16 Comments

There were so many things to see at Maker Faire that the booths spilled out of the buildings and into various tents on the grounds. One of the most interesting tents was packed with tables showing off CNC machines and that’s where we ran into two that are familiar, and still amazing.

First up is the handheld CNC router which we saw all the way back in 2012. It’s a spectacular piece of tech that adds a base to a handheld router. The base gives the tool a touchscreen system, the ability to precisely track it’s location, and adjustment motors to move the cutting bit in order to correct for imperfections in operator movements. It’s really amazing and we are happy to see they have formed a company called Taktia around the concept and are heading for crowd funding soon.

The second half of the video shows off the Nomad CNC mill which we covered at the end of April. Carbide 3D had a hugely successful (more than 10x the goal) Kickstarter that they tried to blame on the support of Hackaday readers. It’s a no-brainer that this machine is the one to watch, as even our hacked camera work doesn’t lose the fact that it can produce rock-solid results.

Arduino Zero Hardware Is Not Just For Beginners

May 21, 2014 by Mike Szczys 72 Comments

We stopped by the Atmel booth at Maker Faire to gawk at the pre-production Arduino Zero boards they were showing off. [Bob] gave us a rundown of everything the new board offers, and it’s better than we imagined when we heard about it last week.

I may be an odd egg in that I don’t like to use an IDE when developing uC firmware. Generally I rock the text editor and a makefile for 8-bit, adding OpenOCD and GDB when working with ARM. I probably shouldn’t be surprised that there is already OpenOCD support (and by extension GDB support) for the Arduino Zero. In fact, that’s how the Arduino IDE flashes the board. This should have been obvious since the board is really just a breakout for the SAM D21 chip which is already supported.

Riffing on the thought of this being a breakout board, we think they did a pretty good job. There are two USB connectors; one let you access the board as a device or a host while the other connects the debugging hardware. If you’ve never used an On Chip Debugger before it’ll change your life so do give it a try. When you do move past the initial prototyping phase of your project you can still use the Zero as a debugging tool. There’s an unpopulated 10-pin header (not sure if the small pitch header comes with it or not) which can be used to interface with a target board. [Bob] also spent some time talking about the configurable 6-pin header which allows you to choose from a range of hardware protocols (SPI, TWI, etc.).

Unfortunately we still don’t have info on the availability timeframe or pricing information. There was one hiccup with this pre-production run (two signals were swapped on the PCB) and they need to spin another board, populate, and QA before they can green-light the final product.

Editorial Note: Atmel advertises on Hackaday but this video and post are not a product of that relationship. Hackaday doesn’t post paid content.

ISEE-3: Ready To Come Home

May 16, 2014 by Brian Benchoff 31 Comments

The team working to reboot the ISEE-3 satellite hurtling towards an August encounter with Earth is hard at work. They’ve put up a crowdfunding page, and now that they’re completely funded (don’t stop donating, btw), they’re starting to go deeper into the waters that will allow them to capture a forgotten satellite.

The project put up a status report going over what they’ve accomplished so far, and what work has yet to be done. For a few months now, they knew both transmitters aboard the craft were operational, but they were not sending telemetry. The team has gone through the documentation, came up with a set of commands, and are currently en route to Arecibo to transmit those commands.

Two ground station transmitters are being constructed, one specifically built to be installed at Arecibo for this application. The other is a portable, self-contained 700 watt transmitter that will be used at the official ISEE-3 ground station in Morehead State University in Kentucky.

With transmitters taken care of and receiving handled by an SDR from Ettus Research, a lot of work has focused on the command and telemetry systems. In 1978, the user interface for commands and telemetry was primitive to say the least. The team is now working on a system built-in Labview that’s much easier on the eyes than the vintage text terminal screens.

So far, signals from ISEE-3 are planned to be received at Arecibo, Morehead State, and Bochum observatory in Germany. This will give the team extremely good coverage for most of a day, and there are other ground stations in California that will extend the time the team is able to communicate with ISSE-3 each day by a few hours.

There’s still a lot of work to be done; the team really doesn’t know what systems are still operating, although most of them did make it 20 years with only one fault. In the next few days, we’ll all get to see if this satellite will be up to the task of coming back home to Earth. If everything goes to plan, ISEE-3 will be on track towards a 17 hour burn to put it on the correct trajectory some time in mid June.

Find The Giant Jolly Wrencher At Maker Faire This Weekend

Check it out, I made something really geeky for Maker Faire. If you’re going to be in San Mateo this weekend for Maker Faire Bay Area, watch for the floating Skull and Wrenches. I won’t be alone, and my compatriots and I will be loaded down with stuff to give away to those who ask for it. If you are hell-bent on finding us, just check this Twitter list as we’ll frequently be tweeting our locations and exploits.

Want to grab a beer with some other Hackaday folk? Even if you’re not attending the Faire, you can take part in the festivities. We’re descending on O’Neil’s Irish Pub on Saturday night. You might want to let us know you’re coming. You can show up unannounced, but we can’t guarantee that you’ll be able to squeeze into the 80-person-pub. If we have way too many hackers overflowing into the street we’ll probably split the party up and go bar hopping. The place is apparently right next to a train stop for your traveling convenience. We just hope to keep things tame enough to make it to Maker Faire again on Sunday morning, but we can’t guarantee that either ;-)
