FPGA With Open Source Propeller 1 Running Spin

fpga-running-p8x32a-and-sidcog

Open Sourcing something doesn’t actually acquire meaning until someone actually uses what has been unleashed in the wild. We’re happy to see a working example of Propeller 1 on an FPGA dev board. That link takes you to a short description and some remapping of the pins to work with a BeMicro CV board. But you’ll want to watch the video below, or rather listen to it, for a bit more explanation of what [Sylwester] did to get this working.

You’ll remember that Parallax released the Propeller 1 as Verilog code a few weeks back. This project first loads the code onto the FPGA, then proves it works by running SIDcog, the Commodore 64 sound emulation program written in Spin for p8x32a processors.

We do find this to be an interesting first step. But we’re still waiting to see what type of hacks are made possible because of the newly available Verilog code. If you have a proof of concept working on other hardware, certainly tell us about it below. If you’ve been hacking on it and have something you want to show off, what are you waiting for?

Hat Hash Hacking At DEFCON

You probably remember that for DEFCON I built a hat that was turned into a game. In addition to scrolling messages on an LED marquee there was a WiFi router hidden inside the hat. Get on the AP, load any webpage, and you would be confronted with a scoreboard, as well as a list of usernames and their accompanying password hashes. Crack a hash and you can put yourself on the scoreboard as well as push custom messages to the hat itself.

Choosing the complexity of these password hashes was quite a challenge. How do you make them hackable without being so simple that they would be immediately cracked? I suppose I did okay with this because one hacker (who prefers not to be named) caught me literally on my way out of the conference for the last time. He had snagged the hashes earlier in the weekend and worked feverishly to crack the code. More details on the process are available after the jump.

The Remaining Hours Are More Than Enough To Get In The Game

thp-time-leftWhether you’re just finding out now or are a procrastination ninja, it is not too late to give yourself a shot at winning that trip to space. The Hackaday Prize is really just getting started. At 11:50pm Wednesday night ( that’s PDT on 8/20/14, or 06:50 GMT on Aug 21) we close the entry window and the build phases will begin. That’s right, you don’t actually need to have any hardware done, you only need to document your idea and how you’re going to get there.

Close your eyes and assemble your vision of a connected device. Now open them and start typing. You need to share your overall idea and how you’re going to get there. Draw out a basic system design, and film a video of 2 minutes or less that explains it all. Think this sounds like a lot? You’re wrong… I did it in only a few minutes.

When will you have such a great opportunity to win something awesome and secure the adoration of the hacking masses? Enter now and have no regrets!

[Chris Anderson] Joins The Hackaday Prize As An Orbital Judge

[Chris Anderson] has had many labels in his lifetime: Punk rocker. Technology editor. Best selling author. UAV enthusiast. CEO. He now will also be able to add “Space Enabler” to that list as he joins The Hackaday Prize as an “Orbital Judge”. He will be on the panel choosing the Grand Prize winner (space-goer) from the list of five finalists. He joins the cast of “Launch Judges” who will be narrowing from 50 semifinalists down to 5.

Chances are that you already know [Chris] in one way or another. His book Free: The Future of a Radical New Price was an early analysis of how free and freemium models are changing the way that businesses connect with customers. On the hardware side of things he is the author of The Long Tail and Makers, both of which discuss the specialty hardware market that we so often explore around here. He has been an editor for Nature, Science, and The Economist. He served as the Editor in Chief of Wired for nearly 10 years, and most recently he started DIYdrones, the 50K+ member community that works on open source software and hardware for UAVs and RC controlled flyers. This spawned a company called 3DRobotics, of which he is the co-founder and CEO. 3DR continues to push the frontier of Open Source Hardware for hobbyists and professional drone users.

If you’ve been on the fence until now, this should convince you to take an afternoon to enter your project idea. You have until August 20th to document your concept of an Open, Connected device. Entry is easy and requires only that you outline your idea with a 2-minute video, proposed system diagram, and four project logs which may discuss different aspects of your plan. If you make the first cut of 50 in August, you’ll already be a winner of at the least a $1000 grab-bag of electronics. You’ll also be well on your way having [Chris] study your work as you advance to a functional prototype in November.

DEFCON 22: The Badge Designers

If you go to DEFCON next year (and you should), prepare for extreme sleep deprivation. If you’re not sleep deprived you’re doing it wrong. This was the state in which we ran into [LosT] and [J0nnyM@c], the brains behind the DEFCON 22 badge and all of the twisted tricks that torture people trying to solve the badge throughout the weekend. They were popular guys but wait around until late into the night and the throngs of hint-seekers subside just a bit.

Plans, within plans, within plans are included in the “crypto” which [LosT] talks about in the interview above. We were wondering how hard it is to produce a badge that is not only electrically perfect, but follows the planned challenge to a ‘T’. This includes things like holding off soldering mask from some pads, and different ones on a different version of the badge. Turns out that you just do as well as you can and then alter the puzzle to match the hardware.

Speaking of hardware. A late snafu in the production threw the two into a frenzy of redesign. Unable to use the planned chip architecture, [J0nnyM@c] stepped up to transition the badges over to Propeller P8X32a chips, leveraging a relationship with Parallax to ensure they hardware could be manufactured in time for the conference.

If you haven’t put it together yet, this is that same chip that Parallax just made Open Source. The announcement was timed to coincide with DEFCON.

DEFCON 22: Hack All The Things

This morning I went to a fantastic talk called Hack All the Things. It was presented by GTVHacker. If you don’t recognize the name, this is the group that hacked the GoogleTV. They haven’t stopped hacking since that success, and this talk is all about 20+ devices that they’ve recently pwned and are making the info public (that link still had oath when I checked but should soon be public).

The attacks they presented come in three flavors: UART, eMMC, and command injection bugs. I’m going to add the break now, but I’ll give a rundown of most of the device exploits they showed off. I found all amusing, and often comical.
