New Event 38 Mission Planner Features

The latest version of Mission Planner for Event 38 has just been released and we have some exciting new features to share. We often develop these items specifically for our aircraft but I like to hear back from the DIY Drones community what features, if any, you think would be useful to have. If anything looks interesting, let me know and we'll work to get it into the main Mission Planner development branch. As always, you can download our version as-is on our…

Free Geotag Utility for Smart Tagging from .tlogs

The latest version of the Event 38 geotagging utility is now available for download and as always, it is available to the wider DIY Drones community. It’s compatible with standard MAVLink telemetry logs. If you’re using telemetry logs to geotag your images and find that the number of CAM messages doesn’t always match the number of images taken by your camera, this…

Process Maps, NDVI and 3d Models for Free

With the Drone Data Management System™ officially out of beta testing, I thought it would be helpful to go through and show new users how they can still use it to process orthomosaics, NDVI maps and 3d models with imagery from any drone for free. This isn't intended to be a…

APM to CHDK Camera Link Tutorial

[Edit 12/31/2015: Note for Pixhawk users that Canon cameras require a 5V pulse to trigger so a voltage step-up from Pixhawk's 3.3V output is required. See compatible cable and link to more instructions here.]

ArduPilot Camera Tie-In Tutorial

This tutorial will show you how to get your CHDK-enabled camera connected to your ArduPilot Mega (APM) without buying any extra hardware or decoding PWM outputs.…

Introducing the E386 Mapping Drone

Our goal at Event 38 is to build products that make aerial data collection for mapping as easy as possible. For a while now, our team has been focused on creating a better autonomous landing solution. At the moment, recovery of a fixed-wing drone requires either a large area…

Drone Data Management System™ Public Beta

Since 2011, Event 38 has built a reputation as a business focused drone and sensor provider. We’ve been very fortunate to work with some of the most innovative drone operators in the world, and we’re really proud of what our customers have accomplished. There’s always been a missing piece of the puzzle though. The tools needed to geotag data, stitch images, calculate…

Event 38 Mission Planning & Mapping Workflow Updates

For anyone using Mission Planner as a ground control station, check out these additions we've made to streamline MP to our workflow. We typically run mapping missions on fixed wing aircraft at Event 38, so these are tailored to that use, but some of our features are more general purpose. I'll outline the features we've added below and open up to…

New NGB Filters and Higher Resolution Camera at Event 38

We've been hard at work improving our popular NGB filter glass over the summer and the latest design is finally in! This design cuts off higher wavelength NIR light around 770nm. That reduces the amount of light crossing over to the Green and Blue channels which are also sensitive to NIR light, especially at higher wavelengths. The results are better than we could have…

Low Cost Thermal Sensor, HemaImager, Now on Kickstarter

Check this out if you're interested in adding thermal capability to your drone. The resolution is lower than FLIR, but the accuracy of the readings seem to be very high (0.2*F). From the Kickstarter Specs…

NDVI Post-Processing in Fiji

A lot of people have been asking me how we post-process imagery coming from one of our, or any other company's, NGB converted cameras. There's a very easy way to run this processing thanks to Fiji and the Photo Monitoring plugin by Ned Horning. I've just written up a quick getting started guide to this software, pasted here for convenience. If you're coming across this…

New, Higher Performance NDVI Converted Cameras

Late last year we released our first version NDVI converted cameras using Schott BG3 filters. Using those filters we were able to generate pseudo NDVI images with a single camera, building off the work of the Public Lab project. After working with faculty at the University of Boston and the …

Bluetooth Telemetry Bridge - Last Chance

Just a friendly reminder, now is the last chance to grab a Bluetooth Telemetry Bridge before the Kickstarter ends tonight at 10:30PM EST. We've already had an overwhelming response and reached our goal in less than 24 hours! After tonight, there will be a bit of delay before we can take any more orders because we'll prioritize Kickstarter…

Tablet Ground Station via Bluetooth Telemetry Bridge

We've been experimenting more and more with tablet ground stations here at Event 38 and have had a lot of success using the DroidPlanner app. The software has been working well for us but we found our ground station setup was really cluttered, the…

DIY Camera Filter Swap on a Canon Powershot


I wrote a few weeks ago about testing out a Schott BG3 filter on an SX260 for detecting vegetation stress remotely. That post and the results of this conversion are posted here. We’re now selling both those filters individually as well as pre-modified cameras at Event 38 for those interested in testing them out, but be…

Parachute Recovery Tests

I've been working for the last few weeks on developing a parachute recovery system for E382s to reduce the need for manual flying. I know from my own experience that any time a human is at the controls, the risk of crashing is significantly higher. Parachutes have been made for small aircraft before but they're often implemented in an expensive or complicated way. The…

DIY Samsung Trigger for APM


In this post I’ll describe how to make your own cable to trigger the Samsung mirrorless cameras NX20, NX210 and NX1000. We’ll be using an ArduPilot Mega 2.5 to do the triggering but you can use any Arduino or even a soldered push button.

What you’ll need:

  • Any 2 or 3 wire cable – I use a 30cm Futaba servo extender which I cut the female end off…

RTF Hexacopter from Event 38 - Aphex

I’m happy to announce the release of our first multirotor drone at Event 38, the Aphex aerial photography platform. This hexacopter is based on the 3DR Hexa frame. It comes ready to fly with a 2-axis stabilizing camera mount for taking aerial photographs. We modified the camera mount so it can now take images not only at moderate angles but also straight down for super…

Using UAS for Environmental Studies

At Event 38, part of our goal of offering low-cost, ready to fly UAS is to promote their adoption into a variety of alternate uses. We recently partnered with the physics and engineering departments of Universidad de Chile to explore the viability using an E382 to study low altitude atmospheric effects.

As a preliminary study, we set out to measure the…

Reprocessing Old Aerial Photos

I decided to run some older imagery I came across the other day through photoscan and came up with some pretty cool results. Above is the park behind 3d Robotics where I used to fly after work. Below is an aerial shot of the 3DR neighborhood.…
