Video: Drone captures fireworks

Sure, 4th of July fireworks from the ground-level are great; however, nothing quite compares to the eye-level view of a drone.

Just this past weekend, Nashville entrepreneur Robert Hartline decided to capture the city’s Independence Day fireworks show from the air using a drone-and-camera apparatus as part of a promotion for a new venture, USA TODAY reports.

This isn’t the first time fireworks have been captured from up-above using an unmanned aerial vehicle (UAV). In May, YouTuber Jos Stiglingh mounted a GoPro Hero 3 Silver camera onto a DJI Phantom 2 quadcopter to provide his audience with a firsthand look at a stunning airborne spectacle in West Palm Beach, Florida. Paired with tenor Andrea Bocelli’s “Con Te Partiro,” the video has now been viewed over 6.5 million times.

What’s even more amazing is that neither ‘copter was damaged in the process.

Besides the recreational filming of fireworks, UAVs are set to soar across an array of industries, ranging from real estate and aerial photography to action sports and Hollywood.

Paragliding with a portable EKG

Andrew of derefnull.org recently designed a portable EKG and integrated it with a GoPro. He says he wanted to see the heart respond to environmental stimuli “while doing really cool stuff” like paragliding.

“At the heart of the system (pun intended) is an Instrument Amplifier circuit, which amplifies the differential signal generated by your heart muscle,” Andrew explained.

“The amplified signal is fed into an Analog-to-Digital converter on the [Atmel-based] Arduino Uno (ATmega328 MCU), and then saved to an SD card. The EKG trace is generated after-the-fact with custom software that performs filtering, heartbeat detection and a scrolling video overlay.”

The EKG – which draws power from a single 9V alkaline battery – is built into a plastic project enclosure box.

“I cut holes for access to the LCD screen, on/off switch, start/stop button and status LED. Nylon webbing is threaded through the flange holes to create a belt of sorts, and I can wear this around my belly, or waist,” he said.

“The electrodes are soldered to a 3.5mm audio jack, which is easily inserted and removed through the side of the enclosure.”

Meanwhile, two electrodes are worn on the upper chest (above the pectoral muscles) and one on the lower abdomen. The signal from the chest electrodes are fed into the amplifier circuit on the Olimex EKG/EMG shield and amplified nearly 1000 times. According to Andrew, the signal is also band-pass filtered for noise, with the third worn electrode acting as a driven signal to help improve overall integrity.

“To help synchronize the data with the video, I added an LED and piezo buzzer that blink/buzz at the beginning of each data capture. The data filename is broadcast via LED and buzzer in morse code,” he added. 

”In theory, I can use the audio of the piezo buzzer to automatically sync the data to the video track. In practice, the piezo buzzer was too quiet to be heard by the GoPro [so] I will work on this for the next iteration.”
