I realized that I never updated the blog with a picture of my completed long-board.
Well, it has been built nearly a year ago and I have been using it ever since.

Aluminum Long Board Project

I have been riding my longboard for some time around campus but over time i realized that every one had the same plane old wood longboard. I wanted something new, special and hand made. So I started designing my own longboard. I first made a design that looked like a spider web. Everyone knows spider webs are cool Well being an engineering student I couldn't resist doing a stress analysis on my design . It looks like spider webs dont leave enough supporting material to prevent the board from over flexing.
I had to re-design my longboard with more suport material in it. The result was this. I think it is not as cool as spider web but still cool.

 I started machining it last night and so far so good. I have half of it done just need to flip it over and machine the other half. Ill post a time laps of the build when i edit the footage.

I have this 46 inch TV in my dorm. It is the focus point of the whole room however there is one problem: it doesn't have a remote ( got lost when I was moving it from my house to my dorm). I thought about getting my self a universal remote from Wallmart for 10 bucks but that is not the hacker way. I took the more complicated route. I made a IR emitter that works off the audio jack of my iPhone. I am now learning how to write iOS apps to make this work just like a normal remote. I currently change my TV by playing a audio file on iTunes ( which gets annoying fast ).

It has been a long time since my last update. Since then I have gone to Turkey, came back from Turkey, build my Quad, destroyed my quad when one of the ESCs failed, Rebuilt it with a new frame, didn't like the new frame, Made a Y6 frame, built the y6, took the y6 to HouSecCon and used it as eye candy during Zac Hinkel and I's drone presentation and last but not least I just cut my T-6 frame. So over all I have been a busy boy. I have my y6 flying with out any problems but I decided that KK2.0 is just not really what I want. In the near future i will have an APM2 to fully automate the quad for doing topography mapping and 3D mapping.
Other then that I have designed an phone/water bottle holder for my bed at the dorms. I have been having to put my phone under my pillow ever since I built my bed fort to keep the sun out in the morning and the light out when my roommate is studying. The only solution? Design a holder! So I did.... and this is what i came up with:

I was at the Tx/Rx Labs in Houston today to finish my quad today during the open house. I did more then finish working on it..... I maidened  it in front of  about 10 people I am glad it didn't tip over the side crashing.

Here is more details on the quad. 

Bill of materials


The booms are from Home Depot. They are towel racks.

The nuts and bolts are also from Home Depot.

The frame is a custom design that I cut on the laser cutter ( if any one wants me to cut them one just leave a message in the comments)

During the maiden I was surprised at the KK2s stability right out of the box. It did have some oscillation but that can be easily tuned out. I am glad I didn't have to bother with pots like I had to when using the older KK boards to get it to the point where it would not tip over.
I just gave it throttle and it took off without any problems.

I am going to finish tuning the PI in the morning and after that I can fly it a bit more aggressively to see what this thing will do before i have to take it apart to take it to Turkey.

I'll post a video when i get a chance.

Gig'em, Aggies !

Well this is my latest project. I have been working on my own quad design for some time. I wanted a cheap fold-able quad that I can take overseas with out a problem. After a few days of designing this is what i came up with.
I used 5mm plywood because it is so easy to cut with a laser cutter and its super cheap. I got enough plywood to make at least a hundred of these things for just 10 bucks from Home Depot. For the booms I used Aluminum towel racks also from Home Depot costing me only about 8 bucks for all 4. With the frame out of the way lets talk about the most expensive part of the quad... The motors and the speed controllers. I lucked out on those and got everything i needed from a guy on RCGroups.com for only 80 bucks shipped to my front door. That also included a HK KK flight controller. 
My current cost is in the low 100s right now. Considering this is a 900mm quad that's not a bad price at all. 

Things I have left to do:
-Add the power distribution board and solder up the ESCs to it
-Add the flight controller and the Rx
-Fly it ! 

My batteries should be here tomorrow or by Friday I will try to trim it out and get it flying by the weekend before I go to Turkey for the summer. ( Contemplating about taking the quad with me or not)

Have a Happy 4th and Gig'em !

Update as I promised. I finished up wiring my V1 board on a spare proto board. But as I was soldering everything up I realized that I had no way of telling the arduino that if the fridge door is open or if its closed. 
In order to solve this problem I decided to install a reed switch. I will use a magnet from a hard drive to turn the switch on and off. But adding a new component means new code to write but it shouldn't be that bad.

For the board I'm going to etch the PCB this time to have a nicer looking board. That way I can reduce the chance of a bad solder joint or a loose jumper wire. On top of that it looks cool. Isn't that the reason for this project any way ?


New layout
V1 Board
The wiring doesn't look that purdy..... but it does the job!
