AT LAST!!! The first time that I could really test the IR sensors during the flight. Currently have two sensors, one at the front and one at the back. I used my right hand as the obstacle to activate the sensors, whenever I felt comfortable enough to take my hand of the stick. The unit gently moved to opposite direction each time Really cool!

I will increase the impact of the sensors a little bit to make the unit react faster and will add 4 more sensors in all directions.

I decided to go with the hard one again… Will use what I learned to try building a GPSless position hold system via a GY-521 sensor board + Arduino. This is a pretty cool little board which has accelerometers and gyros. Below data is from my serial monitor… Need to build a solid algorithm using the accelerometer data. Hmmm…

AcX = -2200 | AcY = -68 | AcZ = 17424 | Tmp = 31.82 | GyX = -501 | GyY = -38 | GyZ = 249
AcX = -2244 | AcY = -36 | AcZ = 17292 | Tmp = 31.97 | GyX = -444 | GyY = -22 | GyZ = 173
AcX = -2224 | AcY = -52 | AcZ = 17328 | Tmp = 31.87 | GyX = -450 | GyY = -64 | GyZ = 258
AcX = -2260 | AcY = -204 | AcZ = 17236 | Tmp = 31.92 | GyX = -432 | GyY = -59 | GyZ = 231
AcX = -2192 | AcY = -36 | AcZ = 17232 | Tmp = 31.92 | GyX = -436 | GyY = -51 | GyZ = 167
AcX = -2308 | AcY = -44 | AcZ = 17268 | Tmp = 32.01 | GyX = -513 | GyY = -15 | GyZ = 267
AcX = -2232 | AcY = -216 | AcZ = 17264 | Tmp = 31.97 | GyX = -472 | GyY = -2166 | GyZ = 252
AcX = -2108 | AcY = -2012 | AcZ = 15580 | Tmp = 31.82 | GyX = 96 | GyY = -935 | GyZ = 5553
AcX = -1040 | AcY = -2932 | AcZ = 18424 | Tmp = 31.87 | GyX = -2685 | GyY = 4202 | GyZ = 3258
AcX = -3316 | AcY = -284 | AcZ = 19688 | Tmp = 31.92 | GyX = 633 | GyY = -435 | GyZ = -1965

Implementation of what I learned with this project to my indestructible Mono.

The new indestructible MonoBot. No more replacing servos, fixing landing gears, etc…. This unit is extremely durable and light and will be the new base for my ongoing Arduino tests. Flies like a charm!

This is my new carbon fiber unit that I will use for testing and experimenting sensors and position hold systems, as a part of my ongoing arduino project. This is the maiden of this unit. After seeing that it flies in the first couple of seconds, I felt comfortable enough to immediately test the GPS. I tweaked the code earlier to make the GPS to refresh the position hold position as the point where the stick is released. In the old version, when the stick was released, the GPS would take the unit where the GPS hold was originally initiated. However, with the change, I could successfully re-assign the new position hold coordinates as the point where the stick is released. This will be very useful in many projects. I call it the crawl mode. thx

This will be my IR radar if I can successfully read the IR sensor at certain angles. I will be able to read theoretically infinite (in reality 8) angles with only 2 sensors. These are very good sensors with over 1 meter range and they are immune to daylight. https://www.youtube.com/watch?v=uEnV...ature=youtu.be
