Developed On Hackaday: Let’s Build An Electronic Hackaday Badge

August 17, 2015 by Anool Mahidharia 44 Comments

We’re going to build an electronic Hackaday Badge, and by “we”, I mean Hackaday community members who are passionate about the project.

I’ll be leading the charge. I had a great learning experience the last time I helped design the e-paper badge for the 2013 Open Hardware Summit, and hope to learn a lot along the way this time too. Since then, Badges have come a long way – at cons like DEFCON, LayerONE, Shmoocon, The Next Hope, Open Hardware Summit, The EMF, SAINTCON, SXSW Create, The Last Hope, TROOPERS11, ZaCon V and of course the rad1o from this year’s CCCamp. Word is that this year’s Open Hardware Summit badge is going to be pretty kickass too. So, we have some very big shoes to fill. But this doesn’t have to be about “my badge is better than yours”. And this badge isn’t meant to be specific to any single con or event. So what does the Badge do, then? “It’s a physical extension of the hackaday.io community, made specifically for hacker gatherings of all types and sizes.”

Developed On Hackaday: Front Panels And Beta Testers Program

May 27, 2014 by Mathieu Stephan 7 Comments

We’re pretty sure that most of our readers already know it by now, but we’ll tell you anyway: the Hackaday community (writers and readers) is currently developing an offline password keeper, the Mooltipass. As it has been more than two weeks since we wrote an article about our progress, today’s will be about the Mooltipass front panels and our beta testers program.

At the end of our mechanical design rundown article we showed that we were originally planning to put a slightly tinted acrylic panel on top of our device. We however could still make out the Mooltipass’ insides, which wasn’t in line with the nice professional look we wanted. We then designed another front panel, one which was transparent above the OLED screen/LEDs and opaque (black) on top of the rest. To our surprise the result still wasn’t as good as we had hoped, as the contrast between the front panel and the screens/LEDs was too big. We finally came up with the panel shown above (see GitHub repository folder) which combines the two techniques previously described. As it is still in China, we’ll show you the final result when we get it in our hands.

We launched around 10 case prototypes in production, they will soon be shipped to our current contributors/advisers together with the smart cards chosen by Hackaday readers. In the meantime we sent our official call for beta testers to our mailing list recipients and hackaday.io followers, in which we asked them to fill a small form that will allow us to know them a bit better. We asked about their home/work computer setup, their level of expertise, their willingness to contribute to the prototype cost and finally specifics about who would use the Mooltipass they’d receive. We are targeting a broad range of users but also testers that will provide us with detailed feedback and clear bug reports.

We also spent quite a while searching for cheaper alternate parts that could be sourced in relatively big quantities. This is usually an overlooked aspect of a project so we preferred to tackle this as soon as possible. In a few weeks the contributors and I will receive all the components required to assemble our final prototype (front panels / case / top & bottom PCBs / smart cards) and it will be time to write a new update.

Developed On Hackaday: The Current Project State

February 11, 2014 by Mathieu Stephan 22 Comments

It has been quite a while since we updated our readers with the current state of the Mooltipass, the offline password keeper project developed by the Hackaday staff and community.

A few weeks ago we presented you the designs that our mechanical contributors had thought of. We organized a poll to get a feeling of what the favorite designs may be and around one thousand people expressed their opinions. The first three favorite designs with their corresponding votes were:

Developed On Hackaday: The Designs

January 20, 2014 by Mathieu Stephan 34 Comments

We know that many of our readers have been impatiently waiting to discover what the Hackaday community-developed offline password keeper project will look like. Today we present you several designs that our mechanical contributors came up with and we will ask you to give your opinion about them. Obviously these are just preliminary cases that may evolve along the way, but we will only produce the electronics for the designs you prefer.

All the designs are embedded after the break, with a multiple-choices poll to express your interest. You may also want to join the Mooltipass Google Group in case you’d want to talk about the designs in more depth or meet their creators. On the firmware side, I just finished soldering many mooltipass prototypes that will be shipped in the coming days to our firmware developers. As you may have noticed, this project is gaining speed!

Developed On Hackaday: We Have Pixels!

January 12, 2014 by Mathieu Stephan 32 Comments

It has been a while since we kept you informed about the current state of the Mooltipass project. Well, several days ago we finally received the PCBs we got produced at Seeedstudio. Keep in mind that this first version (shown in the picture above) is only meant to check that the chosen components can suit our needs while our mechanical contributors work on their designs. Moreover, we may add empty footprints for our readers that may want to hack the device.

After a few hours of soldering and a few days of coding, we finally got a basic firmware running. The OLED screen is easily readable and has an amazing contrast (the picture doesn’t do it justice). So far we checked all basic functionalities of the on-board components and it’ll still take a few days/weeks to be certain that we can settle with them. We are therefore starting to ship a few platforms to the firmware developers that want to work on the core functions of the Mooltipass. So if you’re an experienced C developer and have some spare time, you may get onboard by contacting me at mathieu[at]hackaday[dot]com or by joining the Mooltipass Google Group.

In a few days we will publish the designs that our mechanical guys came up with and we’ll ask you to let us know which ones are your favorites. Depending on how things will go, we may produce PCBs for several of them to select our final design based on user experience and ease of use. We look forward to hearing your feedback in the comments section below!

USBPass – A Mooltipass-like Project

January 1, 2014 by Mathieu Stephan 15 Comments

In our Developed on Hackaday series some readers may recall a sentence we wrote: “if one’s idea is not yet in the market, it’s either completely stupid or people are already working on it”. Well, [Josh] casually mentioned that he was also working on an offline password keeper after having recently subscribed to our google group. Similarly to the Hackaday-developed platform, the USBPass is connected to a computer via USB and is detected as an HID keyboard. As you can see in the picture shown above, it uses very few components: an ATMega32U2, a USB connector, three buttons and a few passives chips.

A total of 20 passwords can be stored in the microcontroller’s memory, which can be ‘typed’ by the platform using the push buttons. The USBPass firmware is based around the LUFA USB stack, to which [Josh] added HID report functionality to allow data transfer from his desktop application. The latter uses the Linux/Windows/OS X HID API library so bringing his software to other operating systems can be done in no time. All the project resources can be found on GitHub, while [Josh] is currently working on a B revision which will include an OLED screen.

Developed On Hackaday: First Version Of The Hardware

December 18, 2013 by Mathieu Stephan 42 Comments

The Hackaday writers and readers are currently working hand-in-hand on an offline password keeper, the mooltipass (click to see the project description).

Next in our Developed on Hackaday series, we present the first version of our schematics. There’s already been a lot of discussions going on in our dedicated Google group, mainly about the project’s basic functionality. Because our firmware developers wanted to get to work, we decided to send the first version of our hardware into production a few days ago. Before going through the schematics, let’s review the required list of the mooltipass’s core components:

an easily-readable screen
a read-protected smart-card
large flash memory to store the encrypted passwords
an Arduino-compatible microcontroller with USB connectivity

We’ve been drowning in component suggestions from motivated hobbyists, so we figured we’d make the mooltipass v1 as simple as possible and then move from there. Given this device is developed on Hackaday, we also wanted future users to modify it, building completely new projects based around these main components. Keep reading for our schematics…
