Hackaday Links: March 11, 2018

Guess what’ll be wrapping up in just two weeks? The Midwest RepRap Festival, the largest con for open source 3D printing in the world. MRRF is going down in Goshen, Indiana on March 23rd through March 25th. Tickets are free! If you’re looking for a hotel, I can speak from experience that the Best Western is good and close to the con, and I haven’t heard anything bad about the Holiday Inn Express.

Want to go to a convention with even weirder people? Somehow or another, a press release for Contact In The Desert, the largest UFO conference in the …read more http://pje.fyi/QKf2ql

You Can Learn a Lot From a Blinkenrocket

At this year’s Chaos Communication Congress, we caught up with [muzy] and [overflo], who were there with a badge and soldering project they designed to teach young folks how to solder and program. Blinkenrocket is a basically a 64-LED matrix display and just enough support hardware to store and display animations, and judging by the number of blinking rockets we saw around the necks of attendees, it was a success.

Their talk at 34C3 mostly concerns the production details, design refinements, and the pitfalls of producing thousands of a thing. If you’re thinking of building a hardware kit or badge …read more http://pje.fyi/QDnY24

Hackaday Belgrade Call For Proposals Now Open!

Prepare yourself for the return of Hackaday Belgrade! Our premier European conference — Hackaday Belgrade — is on 26 May and we want to hear what you’ve been working on. The Call for Proposals is now open. We seek talks and workshops exploring the most interesting uses of technology and the culture that goes along with it. This includes design, prototyping, research, manufacturing, and the stories of people and progress that move hardware hacking forward.

We’ve booked Dom Omladine for the event because it was perfect for our previous Belgrade conference in 2016. The sold-out conference became a living organism …read more http://pje.fyi/QCKGt9

Samy Kamkar: Reverse Engineering for a Secure Future

Show of hands: how many of you have parked your car in the driveway, walked up to your house, and pressed your car’s key fob button thinking it would open the front door? We’ve probably all done it and felt a little dopey as a result, but when you think about it, it would be tremendously convenient, especially with grocery bags dangling off each arm and the mail clenched between your teeth. After all, we’re living in the future —  shouldn’t your house be smart enough to know when you’re home?

Reverse engineer par excellence Samy Kamkar might think so, …read more http://pje.fyi/Q8cw8W

34C3: Fitbit Sniffing and Firmware Hacking

If you walked into a gym and asked to sniff exercise equipment you would get some mighty strange looks. If you tell hackers you’ve sniffed a Fitbit, you might be asked to give a presentation. [Jiska] and [DanielAW] were not only able to sniff Bluetooth data from a run-of-the-mill Fitbit fitness tracker, they were also able to connect to the hardware with data lines using test points etched right on the board. Their Fitbit sniffing talk at 34C3 can be seen after the break. We appreciate their warning that opening a Fitbit will undoubtedly void your warranty since Fitbits don’t …read more http://pje.fyi/Q88ZYJ

34C3: Hacking into a CPU’s Microcode

Inside every modern CPU since the Intel Pentium fdiv bug, assembly instructions aren’t a one-to-one mapping to what the CPU actually does. Inside the CPU, there is a decoder that turns assembly into even more primitive instructions that are fed into the CPU’s internal scheduler and pipeline. The code that drives the decoder is the CPU’s microcode, and it lives in ROM that’s normally inaccessible. But microcode patches have been deployed in the past to fix up CPU hardware bugs, so it’s certainly writeable. That’s practically an invitation, right? At least a group from the Ruhr University Bochum took …read more http://pje.fyi/Q81W8x

34C3: The First Day is a Doozy

It’s 5 pm, the sun is slowly setting on the Leipzig conference center, and although we’re only halfway through the first day, there’s a ton that you should see. We’ll report some more on the culture of the con later — for now here’s just the hacks.

Electric Car Charging Stations: Spoofing and Reflashing

Electric autos are the future, right? Well, for now we need to figure out how to charge them. All across Germany, charging stations are popping up like dandelions. How do they work? Are they secure? [Mathias Dalheimer] bought a couple loading stations, built himself a car …read more http://pje.fyi/Q7slmk

Christine Sunu Proves the Effect of Being Alive on Hardware Design

Modeling machines off of biological patterns is the dry definition of biomimicry. For most people, this means the structure of robots and how they move, but Christine Sunu makes the argument that we should be thinking a lot more about how biomimicry has the power to make us feel something. Her talk at the 2017 Hackaday Superconference looks at what makes robots more than cold metal automatons. There is great power in designing to complement natural emotional reactions in humans — to make machines that feel alive.

We live in a world that is being filled with robots and increasingly …read more http://pje.fyi/Q3vRsk

Mathieu Stephan : The Making of a Secure Open Source Hardware Password Keeper

Mathieu Stephan is an open source hardware developer, a Tindie seller who always has inventory, a former Hackaday writer, and an awesome all-around guy. One of his biggest projects for the last few years has been the Mooltipass, an offline password keeper built around smart cards and a USB interface. It’s the solution to Post-It notes stuck to your monitor and using the same password for all your accounts around the Internet.

The Mooltipass is an extremely successful product, and last year Mathieu launched the Mooltipass Mini. No, it doesn’t have the sweet illuminated touch-sensitive buttons, but it is a …read more http://pje.fyi/Q3kvs1
