Custom Electric Longboard Controller
After a while my original Wii controller started failing. So I decided to design my own starting from scratch. One of the boards fits perfectly where the original Wii controller PCB fit and the other is a simple receiver that provides a signal to speed controller. These boards incorporate Atmega328p micro controllers and nrf24 2.4ghz modules

Electric Longboard Build
Getting ready to go off the school, I wanted a way to get around campus. I came across a project on Instuctables and decided to have a go at an electric longboard. Believe it or not, I was already familiar with most all of the components. They are mostly parts designed for RC planes and cars.

Final Thoughts
I am very happy with how this build turned out. I have the perfect amount of torque and just enough gearing for great speed (25mph top speed). I may really regret using cheap trucks in the future. Only broken one belt so far. I can get about 5 - 6 miles on the 5000mAh batteries. Happy to answer and questions about the build.

Nighthawk 250 Pro Quadcopter
With a few improvements on my mind I decided to build a new quad. With speed, efficiency, and durability in mind I constructed this new quad.
Here are some pictures from the build:
Frame - NightHawk 250 Pro
I decided to go with a less popular frame, the Nighthawk 250 pro from BestHobbyMall.com. At around $50 for the full carbon frame, I couldn't be happier with the quality. There was plenty of space for all my components.
Motors - EMAX 2204 2300kv
So far, these motors have been great. After several hard crashes, the magnets and bearings have held up very well unlike my old RCX 1804s. I would highly recommend these motors.
ESC - EMAX 12A
A great, reliable choice of ESC. Not much else to say.
Controller - NAZE32 Acro
Instead of running baseflight, I'm giving the cleanflight fork a shot. Not sure how I feel about it yet. The hardware is still my favorite choice when it comes to control boards.
Battery - Nanotech 1300mAH 45-90C 3s
So far these batteries have held up well to high current draws. They outperform my Zippy batteries and I can usually fly a bit longer on these at 5 - 6 mins.
Receiver - FrSky D4R-II
One of my favorite receivers with 8channel PPM and telemetry all packed into a tiny footprint.
FPV - IRC 600mW & 600tvl CMOS
The original camera from my Fatshark stater kit and a high power 5.8ghz transmitter. Working great so far.
Props - HQ5040, HQ5045, HQ6030
5040 - Good props for smaller 1806 motors
5045 - Great for bigger motors that can't run 6" props. Very fast: high pitch
6030 - Good for getting heavier quads in the air.

Prototype Gimbal for 250 Racing Quad
As I build my next 250 quad with the intent of racing down at my local club, I'm looking to fix the problem of the camera pointing at the ground when traveling at a high angle of attack. I designed this gimbal to work with the Fatshark 600tvl FPV camera and a standard 9g servo. Here are some pictures:
As you can see, I use the servo capabilities on the Naze32. This functionality is switched on and off by a switch on my TX. Once again the workbench is a mess.
ZMR 250 Overview
Today I just finished a quadcopter build for a friend. Here are some pictures of the finished product. I'll add the parts list below.
Parts:
Parts:
- ZMR 250 3k Carbon Frame

Suppo 10A ESC Simonk Flashing
When I cheaped out and bought Suppo ESCs, I was faced with the task of flashing them with Simonk. It turns out that the ESCs worked well with the tp_8khz.hex file. After a few hours of aggravating soldering I got four ESCs flashed. This was very helpful http://www.atmel.com/images/atmel-24..._datasheet.pdf
