Saturday was the first Madison Mini Maker Faire. In this case, it’s Madison, Wisconsin (sorry Madison, SD I didn’t mean to get your hopes up) where I live. Of course I’m not the only crazy hardware hacker in the area. As soon as I got there I almost tripped over Ben Heckendorn who also lives in the area.
Check out that incredible Giant Game Boy the he was exhibiting. Okay, you think to yourself: Raspberry Pi and an LCD. Wrong! He’s actually using an FPGA to drive the LCD. Even cooler, it’s using an original Game Boy brain board, which the FPGA is connected to in order to translate the handheld’s LCD connector signals to work with the big LCD.

The latest hardware project from [Bunnie] is the Novena, a truly open source laptop where nearly every part has non-NDA’d datasheets. This is the ideal laptop for hardware hacking – it has an FPGA right on the motherboard, a ton of pin headers, and a lot of extras that make interfacing with the outside world easy.
While the crowdfunding campaign for the Novena included a completely custom laptop, it was terribly expensive. That’s okay; it’s an heirloom laptop, and this is a DIY laptop anyway. With the Novena now shipping, it’s time for people to build their laptops. [Ben Heck] is the first person to throw his hat into the ring with his own build of the Novena laptop, and it’s fantastic.
The second video of the build was dedicated to what is arguably the most important part of any laptop: the keyboard. For the keyboard, [Ben Heck] went all out. It’s a completely mechanical keyboard, with backlit LEDs built around the Phantom PCB with Cherry MX switches. Because this is a DIY laptop and something that is meant to be opened, the keyboard is completely removable. Think of something like the original Compaq luggable, but turned into a laptop that looks reasonably modern.
The laptop enclosure was constructed out of a sandwich of an aluminum and laser cut plastic. These layers were glued and screwed together, the parts were carefully mounted into the case. The USB keyboard was attached directly to one of the chips on the motherboard with a few flying wires and hot glue.
The finished build is fantastic, even if it is a bit thick. It’s the ultimate hacker’s laptop, with an FPGA, Linux, open source everything, and even a cute little secret compartment for storing tools and cable adapters. A great build from one of the best builders around.

Everyone loves Top Gear, or as it’s more commonly known, The Short, The Slow, And The Ugly. Yeah, terrible shame
[Clarkson] the BBC ruined it for the rest of us. Good News! A show featuring the Dacia Sandero drones will be filling the Top Gear timeslot. And on that bombshell…
More Arduino Drama! A few weeks ago, Arduino SRL (the new one) forked the Arduino IDE from Arduino LLC’s repo. The changes? The version number went up from 1.6.3 to 1.7. It’s been forked again, this time by [Mastro Gippo]. The changes? The version number went up to 2.0. We’re going to hold off until 2.1; major releases always have some bugs that take a few weeks to patch. Luckily the speed of the development cycle here means that patch should be out soon.
Need an ESP8266 connected to an Arduino. Arachnio has your back. Basically, it’s an Arduino Micro with an ESP8266 WiFi module. It also includes a Real Time Clock, a crypto module, and a solar battery charger. It’s available on Kickstarter, and we could think of a few sensor base station builds this would be useful for.
[Ben Heck] gave The Hacakday Prize a shoutout in this week’s episode. He says one of his life goals is to go to space. We’re giving that away to the project that makes the biggest difference for the world. We’re not sure how a [Bill Paxton] pinball machine fits into that category, but we also have a Best Product category for an opportunity to spend some time in a hackerspace… kind of like [Ben]’s 9 to 5 gig…
[Jim Tremblay] wrote a real time operating system for a bunch of different microcontrollers. There are a lot of examples for everything from an Arduino Mega to STM32 Discovery boards. Thanks [Alain] for the tip.
45s – the grammophone records that play at 45 RPM – are seven inches in diameter. Here’s one that’s 1.5 inches in diameter. Does it work? No one knows, because the creator can’t find a turntable to play it on.
Are we betting on the number of people who don’t get the joke in the second paragraph of this post? Decide in the comments.
[Ben Heck] is well-known in the circles we frequent for being a consummate modder, tinkerer, builder, and hacker. We’ve seen his XBox 360 laptops, portabalized PS3s, the ultimate glue gun, and shutter shades that are too cool for [Kanye]. Now he’s telling us about something else that’s really cool – The Hackaday Prize.
All you need to be in the running for prizes that range from a thousand dollars in electronic components to milling machines to a trip to space is build a project that is open, connected (smoke signals count), and documented on hackaday.io. Think you don’t have time to submit an entry before the first round cutoff next week? You’re wrong. You can sit down and hit all the requirements in an hour. All you need is an idea at this point, and you have until November to actually build it.
Talking to Hackaday readers IRL gives us the impression that a lot of you have an idea for something cool and spaceworthy, but you just need a kick in the pants to write it down and start building it. Here it is. Go.
I might argue that the best thing about Maker Faire isn’t the booths at all, but the people you’ll run into. To that end, I spliced together a series of these impromptu run-ins that I thoroughly enjoyed. What’s remarkable to me is that these people of not weren’t themselves attracting a crowd. If you want to meet the hackers who you respect in the hacking world, you can still have a casual and friendly conversation with them!
First up is [Jeremy Blum] who is a long-time friend of Hackaday, author Exploring Arduino, and one-year member of the Google[x] team. We ran into him along with [Marcus Schappi], CEO of Little Bird Electronics in Australia. [Marcus’] crew recently saw a successful crowd-funding run with the Micro-view.
Next up is [Ben Heck] of The Ben Heck Show. He talks a bit about his recent hack of a pair of texting radios using the eRIC radio modules and he riffed on his past robotic luggage project as well.
The rest of the video is devoted to Hackaday alum. I ran into [Caleb Kraft] who recently started as Community Editor over at MAKE, and [Phil Burgess] who now builds gnarly projects for Adafruit. The clip wraps up with [Ian] from Dangerous Prototypes. He’s fresh off of his Hacker Camp in Shenzhen which covered everything from reballing BGA components by hand, to finding good deals on custom wardrobe, and making sound gastronomic choices while in China.
We talked to a horde of people over two days. Perhaps it was the foam Jolly Wrencher that I wore around? But the point is that everyone at an event like this is interesting to talk to, approachable, and well worth the cost of entry. If you haven’t been to a hacking convention it’s time to start looking around for the one nearest you!
For how many can be found on the workbenches and in the toolboxes of makers and hackers the world over, finding a glue gun that does more than just heat up and drip glue everywhere can be a challenge. [Ben Heck] finally solved this problem with a hot glue gun that’s more like an extruder from a 3D printer than a piece of junk you can pick up at Walmart for a few dollars.
By far, the most difficult part of this project was the glue stick extruder. For this, [Ben] used a DC motor with a two-stage planetary gear system. This drives a homemade hobbed bolt, just like the extruder in 99% of 3D printers. The glue stick is wedged up against the hobbed bolt with a few 3D printed parts and a spring making for a very compact glue stick extruder.
The electronics are a small AVR board [Ben] made for a previous episode, a thermistor attached to the hot end of the glue gun, a solid state relay for the heater, and analog controls for speed and temperature settings. After finishing the mechanics and electronics, [Ben] took everything apart and put it back together in a glue gun-shaped object.
The finished product is actually pretty nice. It lays down constistant beads of hot glue and thanks to a little bit of motor retraction won’t drip.
You can check out both parts of [Ben]’s build below.

[Ben Heck] is no stranger to building Xbox 360 laptops. Over the years he’s built dozens, but for this week’s episode of The Ben Heck Show he’s throwing down the gauntlet and building the smallest Xbox laptop ever.
The latest and greatest Xbox laptop build is based around the newest and smallest $199 4 Gig Xbox. A few compromises had to be made to turn this console into a laptop, though: The power that would have gone to a Kinect was repurposed to power the very thin 15.6″ LED LCD, while the port that would power a hard drive was used to drive a perfboard stereo amplifier. You can check out the official [Ben Heck] blog post here.
The final build is extremely compact and much smaller than [Ben Heck]’s previous Xbox laptop builds. At just 2.125″ thick and 16 ” wide and 9 ” long, it’s quite possibly the smallest Xbox that’s possible to build. Without a new hardware revision from Microsoft (which seems unlikely at this point), this is probably the smallest an Xbox 360 laptop can be. We tip our hat to [Ben], and wish him luck in the next season of The Ben Heck Show.
