I had the chance to participate in the 2011 Warrior Dash in Manchester, TN. Warrior Dash is a 5K Adventure Race that promises to be the “craziest frickin’ day of your life”. Having never done anything other than non-adventure 5K’s, I did some homework before the race to get some tips from veterans. Below you’ll find a summary of those tips and things I wish I had done.
Just posted my DSO Nano Graph Utility. Upload the XML files generated by the BenF firmware and have them graphed in-browser. I’m still working through adding more configuration options, scaling, colors, etc.
Just a quick project I finished up this weekend. I’m a big fan of the Portal series and had printed a companion cube (an iconic ‘character’ from the game) earlier but was unhappy with the droll, boring off-white color of ABS Thermoplastic. So I broke out my paint and brushes and breathed some life into my little cube. Now, mind you, I suck at painting, but it was still a fun project. If you’ve got access to a 3D printer of some kind, hit up this link to the STL file of the Companion Cube on Thingiverse (thanks to emonk for the file). I spray painted the base gray and painted the other parts by hand. I’m sure yours will look better, so if you do something like this with a 3D printed piece, send me your image and I’ll add it to the gallery!
A while back, I had the need to interpret an STL file (stereolithography), which is the general filetype of choice when dealing with rapid prototyping / 3D printing. My side business at the time had released a free 3D model viewer for the iPad, and we wanted to give estimates on prototyping costs whenever someone uploaded one of their own models. I couldn’t find any reasonable STL parsers that would work server-side, so I decided to make my own. The process of doing that, and the resulting files, are described below.
Just a quick push for the psychological effects of cataloging what people (users, customers, or clients) have accomplished. The article below shows how an elementary school corrected all sorts of ill behavior by offering small rewards and achievement tracking during recess. It’s worthwhile to think how you could apply this principle to anything in life, from development to management.
Most successful mobile applications have a handful of traits in common. When developing a mobile app (iOS, Android, etc) it’s important to remember that you’re developing it to be USED. If it doesn’t exhibit several of the characteristics below, it doesn’ t necessarily mean it won’t be useful, but it probably won’t be as penetrating in the market.
So you’ve either just joined us from Part 1, where we learned how to emulate button presses on an RF outlet remote control, or you decided you’d rather skip that portion and go straight to the Network/Arduino link. Either way, I’m glad you’re here. In this tutorial, we will learn how to control the Arduino from a website residing on your own home server. As a disclaimer, I’m aware of several different methods of accomplishing the same thing with various Arduino shields, but I had a home server and no shields, so this is the method I chose. Let’s dive in… Continue reading »
Home automation/security has always been a passion of mine. Sure, there are plenty of commercial kits out there to buy, but I’d rather DIY, especially if it means saving a buck or two. This 2 part series will explain how to cheaply control electrical outlets in your home using an Arduino. Even if you don’t care for home automation, the information from this tutorial will give you serial access to the Arduino over the network, so you can feasibly do ANYTHING, as long as the Arduino is capable of controlling it.

OK guys, my post on fixing the HP vs19d monitor was immensely popular and it looks like it helped a lot of people save some money on buying a new monitor. I’ve had several comments made about people that have successfully applied my fix to the vs19e monitors. To help those of you that may be a little uncertain about applying a fix to a different monitor, I’ve posted images and short instructions for the vs19e below. If you want more explanation, visit the previous post for the vs19d monitor. It goes into a little more depth and detail (vs19d).

**UPDATE: VS19e monitor repair instructions and pics now available: VS19E
The other day, I rolled out of bed in the morning and after a cup of
Gevalia’s finest, I sat down at my computer to check the weather. To
my dismay, upon clicking the power button on my HP vs19d LCD monitor, nothing happened. The blue LED would light up for a few seconds, I would hear a high pitched squeal from inside the monitor, and then nothing. This process would repeat itself until I eventually unplugged the monitor. I later called HP tech support to find that the monitor would have to be replaced. Good thing I bought that expensive three year extension warranty, right? Well, turns out that my warranty only covered my desktop and didn’t extend to the monitor. Excellent.
It seemed like I had one of two options. I could either attempt to fix the monitor myself, or buy a new one. I needed to access my computer to get some files for work, and the HP LCD was the only monitor I had. So, making my decision, I visited NewEgg from work and bought a 19″ WS Acer for a great price.
But I still wasn’t happy that my monitor was only two years old and on its way to the dump. So I decided to crack it open and have a look around. If you’re having a similar problem, follow along, because now my monitor works fine.
