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!
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…

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. In the first post of our first DoH series, we introduced the project and called for contributors. In the comments section, we received very interesting feedback as well as many feature suggestions that we detailed in our second write-up. Finally, we organized a poll that allowed everyone to vote on the project’s name.
The results came in: the project’s name will be mooltipass. We originally had thought of ‘multipass’ but [asheets] informed us that Apple and Canon had both applied for this trademark. [Omegacs] then suggested ‘mooltipass’ as an alternative, which we loved even more. A few days ago we set up a google group which is already very active.
An often under-estimated side of a community driven project is its infrastructure and management. (How) can you manage dozens of motivated individuals from all over the globe to work on a common project? How can you keep the community informed of its latest developments?

Holy cr*p guys… we were amazed by the quantity of positive feedback that was left in the comments section of our last article. We have been featured by Slashdot ! We got plenty of project name suggestions, therefore we organized a poll located at the end of this post to let you decide which one is best. I also received many emails from people eager to start contributing to this offline password keeper project. If you missed the call and want to get involved, it’s still not too late. You can get in touch with me @ mathieu[at]hackaday[dot]com. So far, we have many beta testers, several software developers, one security assessor and a few firmware developers. Next step is to create a mailing list and a Hackaday forum category once the project’s name has been chosen.
Obviously, the very first post of our “Developed On Hackaday” series was to gauge your initial reactions to this ‘new’ project. Notice here the double quotes, as when someone has a new idea there usually are only two possibilities that may explain why it doesn’t exist in the market yet: either it is completely stupid or people are already working on it. In our case, it seems we are in the second category as many readers mentioned they wanted to work/were working/had worked on a similar product. As we’re selfish, we offered them to contribute to this new device.
To ensure that all of our readers are on the same page as to how the device will work we embedded a simple block diagram after the break, as well as a list of all new functionalities that we want to implement given the feedback we received. So keep reading to see what the future holds, as well as to vote on this new project’s name…

We’re pretty sure that most of you already know that a few months ago Hackaday was bought by SupplyFrame, who therefore became our new evil overlords. We do hope you’ve noticed that they’re actually quite nice, and in their divine goodness they recently gave the go-ahead on this series called Developed on Hackaday.
A new project will be made by the Hackaday staff & community and will hopefully be brought to the consumer market. For those who don’t have the time/experience to get involved in this adventure, we want to show and document what it takes to bring an idea to the marketable product stage. For the others, we would like to involve you in the design/development process as much as possible. Obviously, this project will be open source hardware/software. This time around, the hardware will mainly be developed by yours truly. You may already know me from the whistled platform (currently sold on Tindie) or from all the different projects described on my website, which makes this new adventure far from being my first rodeo.
What’s in it for the contributors? During all the steps of this project, we’ll offer many rewards as well as hand-soldered first prototypes of the device so you can start playing/testing it. Nothing is set in stone so every suggestion is welcome. Should we make a Kickstarter-like campaign to manufacture the final product, we’ll only do so once our prototype is final, our partners are chosen and all details of the production process are set and confirmed. In that case, we will just need to gather the required funds to make the device a reality. What are we going to build? Keep reading to find out.

[Mark] recently finished his latest project, where he encrypts wireless communications between the new Intel Galileo and a Texas Instruments MSP430. The wireless interfaces used are the very common nRF24L01+ 2.4GHz transceivers, that had a direct line of sight 15 feet range during [Mark]‘s tests. In his demonstration, the MSP430 sends an encrypted block of data representing the state of six of its pins configured as inputs. This message is then received by a sketch running on the Galileo and stored in shared memory. A python script then wakes up and is in charge of decrypting the message. The encryption is done using AES-128bits in Electronic Codebook mode (ECB) and semaphores are used to prevent simultaneous accesses to the received data. As it is the first project using an Intel Galileo we received, don’t hesitate to send us a tip if you found other ones.
[Scott Driscoll] sent us a link to his Bitcoin explanation a couple of weeks ago. We glanced at it but moved on rather quickly. It’s been popping up here and there and we finally gave it the time it deserved. This video is interesting in that it doesn’t just focus on what the Bitcoin actually is, but how the Bitcoin system works when it comes time for money to change hands.
Quite early on in the explanation he mentions that “The Bitcoin system is amazingly designed so that no trust is needed”. That’s a powerful statement. For instance, if you sell your car, one of your friends will probably tell you not to take a check. That’s because a check means you’re trusting that the buyer actually has a balance in their account to cover the transaction. With Bitcoin the transaction carries its own proof that the currency is available by including information about the past transactions through which those Bitcoins were acquired.
If you have some idea of what public/private key pairs are you’re already equipped to understand [Scott's] lecture. After you make it through the 22 minute video maybe you should get down to work doing some Bitcoin mining at home.
