Monday, February 11, 2013 at 22:55 This post will function as a short walk through for installing and using a TPM on a BeagleBone to implement a Secured Boot (wooo...). I will use an example Secure Boot implementation called libsboot for U-Boot. Let's jump right in with a schematic for the (mostly) required additions to the BeagleBone.

Let's start with poking around where my (our) trust lies when deciding on a SoC for embedded development, using the BeagleBone [SRM] as an example. In this post we'll move trust from CircuitCO's (the Bone manufacture) included bootloaders, Angstrom Linux kernel, and Angstrom development environment to your own compiled bootloaders, kernel, and OS.
Sunday, June 10, 2012 at 12:44 Last month we built an improved version of the DIY Fog Screen found here.
;)
;)
We call it "improved" since we managed to create a thinner sheet of fog, maintain the projection longer (a fog machine is bursty), and thicken the sheet. We use the same technique of creating a laminar flow. Instead of using a window fan we installed 10 120mm [17] computer fans with a variable speed controller [20] to optimize the flow, since we did not know the fog density.
Since the original article doesn't explain the steps / tools / resources required to create a DIY Fog Screen, we'd like to take the opportunity and provide a "how to". In a nut shell, the screen needs to distribute "fog machine"-fog from end-to-end, width-wise, and keep the fog flowing downward sandwiched between two flows of air.
Tuesday, April 10, 2012 at 17:00 Simply: Gelf uses an HTTP client to bridge two or more networks. The iPhone is the primary use case; it has access to both AT&T's mobile network as well as an ad-hoc network. You can bridge the two using Gelf, without running any code on the iPhone, aside from client-side HTML and JavaScript.
This achieves a non-jailbroken, non-rooted, poor-man's network tether. Here's the catch, Gelf needs to run on a device inside each target network. Gelf functions as the L2 tunnel end-points, and the L1 emulation: achieved through an HTTP client.
iPhone, networking, tether in Fun
