Chappie- Self- Balancing Robot: 8 Steps (with Pictures)Arduino is known for its friendly coding environment and large open source user libraries which makes the prototyping really easy. I first started with separate Accelerometer and Gyroscope. But as things progressed, I find it difficult to balance with computational overhead of calculating pitch & roll (using kalman/Complementary filter). When I switched to MPU- 6. To use the DMP of MPU, I used Jeff Rowberg’s. I2. CDev libraries.

To calibrate the mpu, I used Luis Rodenas’ssketch. Now, we can determine the angle of bot with vertical. But how can we calculate the amount of force needed to push bot back to vertical when it is unbalanced by some uncertain degrees from vertical. This is where PID kicks in. Watch Attack Of The Herbals Online IMDB. PID will specify this force which will change according to time and angle by which bot is unbalanced.

I will not go into technical details. Brett Beauregard wrote a nice PID library with explanation if you want. To further speed up the motor response, I used digital. IOPerformance library for fast writing of pins.

Finally for storing PID values in EEPROM of Arduino, EEPROMex library for efficiency and clean code. Complete code can be found on the GITHUB.

Our parents took my younger brother (who just turned 18) and I along on a trip to Europe with them. To save money my parents had my brother and I share a room together.

The Hangover - Wikipedia. The Hangover is a 2. American comedy film directed by Todd Phillips, co- produced with Daniel Goldberg, and written by Jon Lucas and Scott Moore. It is the first installment in The Hangover trilogy. The film stars Bradley Cooper, Ed Helms, Zach Galifianakis, Heather Graham, Justin Bartha, and Jeffrey Tambor. It tells the story of Phil Wenneck, Stu Price, Alan Garner, and Doug Billings, who travel to Las Vegas for a bachelor party to celebrate Doug's impending marriage.

Synopsis, cast and crew, awards, and viewer comments.

However, Phil, Stu and Alan wake up with Doug missing and no memory of the previous night's events, and must find the groom before the wedding can take place. Lucas and Moore wrote the script after executive producer Chris Bender's friend disappeared and had a large bill after being sent to a strip club.

After Lucas and Moore sold it to the studio for $2 million, Philips and Jeremy Garelick rewrote the script to include a tiger as well as a subplot involving a baby and a police cruiser, and also including boxer Mike Tyson. Filming took place in Nevada for 1.

Cooper, Helms, and Galifianakis) formed a real friendship. The Hangover was released on June 5, 2. The film became the tenth- highest- grossing film of 2. The film won the Golden Globe Award for Best Motion Picture – Musical or Comedy, and received multiple other accolades. It is the tenth- highest- grossing worldwide film of 2. R- rated comedy ever in the United States, surpassing a record previously held by Beverly Hills Cop for almost 2.

It is the sixth- highest grossing R- rated film in the U. S., behind The Passion of the Christ, The Matrix Reloaded, American Sniper, It, and Deadpool. A sequel, The Hangover Part II, was released on May 2.

The Hangover Part III, was released on May 2. To celebrate his upcoming marriage to Tracy Garner, Doug Billings travels to Las Vegas with his best friends Phil Wenneck, Stuart "Stu" Price, and Tracy's brother Alan, in Doug's future father- in- law Sid's vintage Mercedes- Benz W1. They spend the night at Caesars Palace, where they relax in their hotel suite before celebrating with a few drinks on the hotel rooftop. The next morning, Phil, Stu, and Alan awaken to find they have no memory of the previous night, and Doug is nowhere to be found.

Stu's tooth is in Alan's pocket, their suite is in a state of complete disarray, a tiger is in their bathroom, a chicken is in their living room, and a baby is in the closet, whom Alan names "Carlos". They see Doug's mattress impaled on a statue outside of Caesars Palace and when they ask for their Mercedes, the valet delivers an LVPD police cruiser. Using clues to retrace their steps, the trio travel to a hospital where they discover they were drugged with Rohypnol ("roofies"), causing their memory loss, and that they came to the hospital from a chapel. At the chapel, they learn that Stu married a stripper named Jade, despite being in a long- term relationship with his abusive, domineering girlfriend Melissa. Outside the chapel, the trio is attacked by gangsters saying they are looking for someone. They flee and visit Jade, discovering that she is the mother of the baby, whose real name is Tyler.

They are then arrested by the police for stealing the police cruiser. After being told that the Mercedes has been impounded, the trio is released when they unknowingly volunteer to be targets for a taser demonstration. While driving the Mercedes, they discover a naked Chinese man named Leslie Chow in the trunk. Chow jumps out of the trunk, beats the trio up with a crowbar and flees. Alan confesses that he drugged their drinks to ensure they had a good night, believing the drug to be ecstasy.

Returning to their suite, they find the boxer Mike Tyson, who orders the trio to return the tiger to his mansion immediately. Stu drugs the tiger with the remaining Rohypnol, and they drive towards Tyson's home in the Mercedes- Benz. However, the tiger awakens midway and attacks them, clawing Phil on the neck and damaging the car's interior. After pushing the car the rest of the way to the mansion, Tyson shows the trio footage of them at his house to help them locate Doug. While driving, their car is intentionally t- boned by a 2. Cadillac Escalade. The passengers are revealed to be the gangsters from the chapel, and their boss Chow.

Chow accuses the trio of kidnapping him and stealing $8. As the trio denies this, Chow tells them he has Doug, and threatens to kill him if his money is not returned. Unable to find Chow's $8. Alan, with help from Stu and Jade, uses his knowledge of card counting to win $8.

Blackjack. The next morning, they meet with Chow in the desert and exchange the money, only to find that "Doug" is the black drug dealer who accidentally sold Alan Rohypnol. With the wedding set to occur in 5 hours, Phil calls Tracy and tells her that they cannot find Doug. When "Black Doug" mentions that, "If you take Roofies, you're more likely to end up on the floor than on the roof," Stu realizes where Doug is. The trio travels back to their hotel where they find a badly sunburned Doug on the roof. Stu, Phil, and Alan had moved him there on his mattress the night before as a practical joke, but forgot where they left him. Doug had thrown his own mattress onto the statue, in an attempt to signal help.

Before leaving, Stu makes arrangements to go on a date with Jade the following week. With less than four hours before the wedding and with no flights to L. A. available, the four quickly drive home.

Along the way, Doug reveals he has possession of Chow's original $8. Despite their late arrival, Doug and Tracy are married, the former learns the damaged Mercedes was a wedding gift, and Stu breaks up with Melissa, having grown tired of her controlling attitude. As the reception ends, Alan finds Stu's digital camera containing photos of the events they cannot remember, and the four agree to look at the pictures together before deleting the evidence of their exploits. All of them, save for Alan, are traumatized by what they see. Bradley Cooper as Philip "Phil" Wenneck, a teacher and the leader of the Wolfpack. Ed Helms as Dr. Stuart "Stu" Price, a dental doctor. Zach Galifianakis as Alan Garner, Doug's socially inept, future brother- in- law, who suffers from ADHD and acts childish.

Heather Graham as Jade, a stripper and escort. Justin Bartha as Douglas "Doug" Billings, the groom, who goes missing for most of the film. Jeffrey Tambor as Sidney "Sid" Garner, Tracy's and Alan's father. The rest of the Garners are portrayed by Sondra Currie as Linda, Tracy's and Alan's mother; and Sasha Barrese as Tracy, Doug's bride and Alan's sister. The cast also includes: Mike Epps as "Black Doug", a drug dealer who is mistaken for Doug; Ken Jeong as Leslie Chow, a flamboyant Chinese gangster; Rachael Harris as Melissa, Stu's bossy, cheating girlfriend; Bryan Callen as Eddie, the wedding organizer; Rob Riggle and Cleo King as Officers Franklin and Garden, respectively; Gillian Vigman as Stephanie Wenneck, Phil's wife; Ian Anthony Dale and Michael Lee portray Chow's henchmen. Matt Walsh portrays Dr.

Valsh and Dan Finnerty plays a wedding singer at Doug and Tracy's wedding. Todd Phillips, the film's director, appears as Mr. Creepy, who appears briefly in an elevator. Mike Tyson appears as himself; Tyson originally refused to appear in the film, but he changed his mind when he found out that Todd Phillips directed Old School, which Tyson liked.[5] Tyson later said that working on the film convinced him to change his lifestyle.[6]Mike Vallely portrays Neeco, the high speed tuxedo delivery man.[7] Las Vegas personalities Wayne Newton and Carrot Top appear as themselves in the photo slide show.[8]Production[edit]"I think part of what's special about this movie is that none of the comedy comes from the characters being clever, like you see in a lot of sitcoms or movies, where the characters actually have a funny sense of humor.

That's not the case in this movie.
