CryptoCape screen casts are posted

After months of work, the CryptoCape is now available at SparkFun Electronics. This cape adds a bunch of security features to the BeagleBone Black. There are seven independent ICs on that board that are connected over I2C. Each IC has a range of features as such, there’s a lot one can do with this hardware. For those who like to read, check out the hookup guide for examples and a walk-through. If you want to listen and watch an off-the-cuff screencast of me performing at demo, check out these screencasts.

I’m very grateful to SparkFun for supporting this idea. I approached them with this idea and applied for their Hacker-in-Residence program. Back then, SparkFun was still calling “capes” “shields”. Now they have a slick BeagleBone Proto Cape in addition to mine, so I’d like to think I helped them get more into the BeagleBone 🙂

I’ve been having a lot of fun with this cape. Of course, I like the security ICs and written a few drivers for them. Even if you are not into security, the onboard ATmega is really fun. It can be flashed from the BeagleBone so you can combine Arduino projects with the Beagle!

I have a few boards on Tindie, that I hand assemble, but this is the first device that’s being professionally manufactured. This is the first, of hopefully more, open source hardware security devices from Cryptotronix. I have a few projects spinning now, but if you support open source hardware, and want to add some hardware security, feel free to contact me.

I’ll be talking more about the CryptoCape, how I got into this, and some project ideas at HOPE X in NYC this summer.

For those with a darker color hat, my DEF CON 22 talk was recently accepted. Once the abstract is posted on the speaker page I’ll announce that here. <evil grin>

Maker Show and Tell at Aleph Objects

Maker Show and Tell at Aleph Objects

Yesterday I presented at Loveland CreatorSpace’s Make Show and Tell hosted by Aleph Objects. As always, I was impressed by everybody’s projects. There was a decent non-member showing as well as the word is getting out about LCS. By the way, we have a physical space now.

Midway through the show-and-tell we receive a tour of Aleph Objects and saw the massive 3D printer array, which is printing parts for more 3D printers. Aleph gives tours frequently so if you are in the Northern Colorado area, you should really check it out.

I was there talking about the CryptoCape and I had brought the first prototype with me. The board has certainly come a long way and there is plenty more to do. I really wanted a crypto board that was hacker-friendly and could be extended in various projects. I keep thinking about new ways to use the cape and I think it’s going to be a lot of fun for people.

In other news, tomorrow is Arduino Day. Swing by SparkFun and pick up some discount Arduinos! I have my eyes set on the pro Minis.

BeagleBone Black I2C References

I’m planning on heavily using I2C for my CryptoCape. I’m still working through issues, but I wanted to capture some of my research in this post. As I’m currently experimenting, please treat this information as notes and not as definitive information. Feel free to post corrections in the comments and I’ll update the content.

The BeagleBone Black (BBB) has three I2C buses (thanks to Smith Winston providing most of this information at his BeagleBoard.org discussion post):

CryptoCape: A new BeagleBone Black Cape Concept

I just registered a conceptual design for a BeagleBone Black (BBB) cape.  I’m calling it the CryptoCape and its goal is to enhance the cryptographic capabilities of the BBB.  I’ve created a project page here.

I’m excited and hopefully others are too, but I will not make very fast progress.  My soldering kit from SparkFun is in the mail and I have to learn to solder 🙂  I’ve requested some free samples of cryptographic Integrated Circuits (ICs) so I will hopefully be testing the basics in the next few weeks.

Stay tuned!
