Malduino Elite Expansion Pins

I finally got enough time to get to actually play with my Malduino Elite which is a pretty sweet open source USB rubber duck. After dorking around with the base code as well as the Hack A Day code, I wanted to know what else I could do with those expansion pins.

Here’s the details I believe that I have correct - though I recommend you check before you burn out your own stuff, reference information pulled from the ATmega32U4:

  | TOP                               |
  |    +------------------------+   O | GND
  |    | ON                     |     |
  |    |   +-+  +-+  +-+  +-+   |   O | VCC+ (5V-USB)
  |    |   | |  | |  | |  | |   |     |
  |    |   | |  | |  | |  | |   |   O | PIN09 - SCLK
  |    |   | |  | |  | |  | |   |     |
  |    |   | |  | |  | |  | |   |   O | PIN10 - MOSI
  |    |   +-+  +-+  +-+  +-+   |     |
  |    |    1    2    3    4    |   O | PIN11 - MISO
  |    |                        |     |
  |    +------------------------+   O | RESET
  |                                   |

ESP8266 and SSDP

I recently picked up an Adafruit Feather HUZZAH with the intent of gluing it together with the SmartThings eco system. This presented an initial problem of needing to do SSDP based communications since that's how SmartThings likes to do LAN based communications. After digging a bit, it becamse clear I was going to have to make some modifications to the library.

Site Move

Well, the time has finally arrived that I am going to ditch Wordpress. Wordpress has just become too much of a headache anymore for just maintaining a place where I can complain about things or keep technical notes for myself and I’m no longer interested in having to fight the security beast; I’ll leave that to the young guns at github.io. My hope is that this will encourage me to get back into documenting my escapades since the last posts have always just been because I was updating Wordpress to prevent some new hack.

Building / Publishing the MS Band Light

Wyatt • • Rants

Today I’m releasing my “first” android application into the store. I say first because it’s not the first I’ve written, but it’s the first one that I’ve actually decided might actually be slightly beneficial to someone else so I put it into the store. When the app goes live, I’ll add a link and all that other fun stuff. In the mean time, you can check out details about what the app can / can’t do and the things I learned along the way here.


The link is live: https://play.google.com/store/apps/details?id=org.hackerforhire.msbandlight

Things I Learned While Building This Application

veho Muvi K-Series Research

Wyatt • • Rants

I recently picked up a veho Muvi K-Series action camera … and the application on Android didn’t work for anything. So I started down my own path.

Rather than put all the details here, I decided that I was going to primarily work out of a git repo (after the jump) in the event that I decided anything worthwhile should be developed to work with the camera over wifi. What I found was a couple of key points:

Due to the fact that the camera’s quality was kind of terrible (random blocks of video would just jump in and out) and the SD card that was shipped with it was broken and wouldn’t function in anything, I decided to send it back. But I’ve collected all of my comments, code, research, etc. into the muvi_kseries_research repository for anyone else that would like to poke, prod, or build their own application for whatever reason. Enjoy and let me know if you found anything helpful.

Python Zlib … Son I Am Disapoint

Wyatt • • Rants

Every now and then, I find myself digging through some arbitrarily compressed binary and in IDA, when you have to keep doing it over and over again, you should write a script or a loader to handle that (as any good programmer would). So I started wiring up a loader in python and thought that I’d use the zlib library to decompress things … boy was I wrong.  Not only did zlib fail to actually work correctly (because it can’t actually handle ZIP files, more on that in a moment), but the error messages were basically the same low-level messages you got out of zlib’s internal functions. Really? This is the best we can do right now? What I tried:

[wyatt@lazarus:~/Downloads]$ zip derp.zip Untitled\ drawing.png
[wyatt@lazarus:~/Downloads]$ cat Whatsnew.txt derp.zip > file.out
[wyatt@lazarus:~/Downloads]$ python
Python 2.7.3 (default, Apr 10 2013, 06:20:15)
[GCC 4.6.3] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
import struct
import zlib
f = open(‘file.out’,‘rb’)
c = f.read()
offset = c.find(‘PK’)
uncmp_size = struct.unpack("<l",c[offset+22:offset+22+4])
z = zlib.decompressobj()
out = z.decompress(c[offset:],int(uncmp_size[]))
Traceback (most recent call last):
File "", line 1, in
zlib.error: Error –3 while decompressing: incorrect header check

This of course fails because zlib doesn’t actually work right with zip files (you’ll find a vauge note to such things in the ) and of course … I should have really known that ZIP isn’t actually zlib. Instead of trying to be clever, I decided to give up and be lazy. What actually worked:

import subprocess

So yes … apparently this is the best we can do with the zlib library.

If you haven’t heard about SOPA / PIPA, then you’ve probably been living under a rock for the past several weeks. I’m not going to talk about why it’s bad, or how it’s oppressing the freedoms provided by the internet because pretty much anyone who would even come across this site knows exactly what’s at stake.

Instead, I encourage you to contact your congressional representatives and light a fire under their asses to reconsider sanity once more as an option for governance.  If you want to know more about SOPA, click here.

As Americans, we continually take for granted the freedoms we have in the country for granted, everyday. Stop taking things for granted and start standing up for them; earn your keep Americans.

Dear GoDaddy: You Suck

Wyatt • • Rants

Dear GoDaddy:

You suck.  Seriously, you suck so bad it makes my vacuum cleaner feel inadequate.  Do you realize how much vacuum cleaner therapy costs these days?  A lot.  And I’m not made of money, which is obvious since I’m using your crappy, cheap-ass tools as my domain registration service.

Can someone down there, preferrably someone without their head permenatnly lodged in their lower digestive-tract, please tell me why, out of all the horrible stupid and awful things you do on your site, that you choose to “automatically renew” a domain ON A CREDIT CARD THAT HASN’T BEEN ON FILE WITH YOU FOR AT LEAST 4 YEARS?!?!?!?  Why for the love of all that is holy and fully of rainbow-shitting unicorns would you have NOT used the credit card you’ve had on file for the past 4 YEARS?!?!?!

Seriously?  What kind of amateur night are you running down there?  All of the stupid crap that your website does (or for that matter, doesn’t do) I can forgive (or at least tolerate) but how in Al Gore’s name can you not get the one piece of software that makes you bank right? What. The. Hell.  I know damn sure that if those vultures at Visa/J.P. Morgan/Best Buy/Citi/Home Depot/etc would have had any, ANY, other account number on file for me they, they would have pounced on that sucker like Sheen on tiger blood and they would have surely charged me some dumb-ass tax for the fact that their system didn’t like it, filed under “account maintenance fees” or some bullshit.

I can deal with the crappy interface, the 9001 ads that I have to click through to effin’ checkout a $8 domain that will ultimately be $50 by the time you’re done adding fees to it, and the insanity that I can’t transfer a domain to another GoDaddy user without a sacrifice to Blood Chicken of Waataephukuistan … but for all that didn’t get raptured today, TAKE MY DAMN MONEY WHEN I TELL YOU TO!

Love to hate, don’t hate to love,

While writing on my cousin’s wall, I came across the following revelation and it seems rather accurate:

Stupid iPhone and Stupid Tethering

Wyatt • • General, Technology, and Tips from a Hack

The last time I installed the tethering packages from Cydia, I lost access to voicemail for 2 weeks, couldn't get them to uninstall, yada-yada-yada, annoying experience. But today, I actually had time to think about how to solve this issue and then it hit me: I'm a moron; I should have seen this last year. Five minutes later, I was on the net.
