PCB fabbing advice

For those of you getting into creating your own PCBs, here's some quick advice:



We use the CADSoft Eagle software (free version can handle up to two PCB layers). It's powerful but pretty hard to learn. For easier to use (albeit more limited)… Continue

New double-sided BlimpBot board!

Our progress towards a $79 UAV mod kit for toy RC blimps is going well. We've now got a much better, two-sided PCB board that we're having fabbed. It's smaller, has more features and now integrates the IR sensors on the same board (Eagle schematic… Continue

Robotic sky writing 4 U

Interview: Martin Müller and the Paparazzi Project (now less DIY!)

We've been following the Paparazzi autopilot project with interest for several years. It's a European open source technology initiative that has created both thermopile (infrared sensor) and gyro-based autopilot hardware, along with quite… Continue

Minimum Blimp V2 PCB files, code

This is just a quick update for those following along with the Minimum Blimp UAV project. We've modded a toy RC blimp and created our own Arduino clone PCB (complete with motor controllers and ports). Here are the PCB files and source code:

Nothing impressive, just my first aerial video.

This is my first aerial video taken with The World Models Super Frontier Senior 46. It's quite a large trainer plane with 2040mm wing span and a lot of dihedral. The fuselage also has a lot of room for my equipments.







The video is taken with the Canon PowerShot A430 digital camera attached to the bottom of the fuselage.







Currently, there is no autopilot system in… Continue

diydrones vs rcgroups vs runryder

Rcgroups & runryder definitely seemed to dry up after diydrones appeared. They're now more focused on promoting businesses while diydrones has attracted the hobbyists, but Ning really needs more organization than the Latest Activity list. Here's a robotic copter update.







Had to point into the wind for more stability. That's also where the sun is.…

Where are the "add blog post" and "add forum discussion" links?!

Last night Ning, our social network hosting platform, pushed out a few new features and in the process changed our look and feel a bit. Among those changes: the "Add a blog post" link at the bottom of the blog listings and "Add a discussion" link at the bottom of the forum listings are gone. So now how do you do those things?



Answer: use the tabs above. You add a discussion topic on the "Forum" tab and… Continue

Autonomous blimps at MAKE NYC meetup

MAKE Magazine's New York City meetup (a hardware hackathon open to all) is next week, on the 27th, and this time they've got blimps!



Here's the announcement:



What can a group of Makers do with a tank of helium? We're not sure! Care to find out? The sixth Make:NYC Meeting includes:



Challenge: Blimps

You've got brains, we've got blimps. Two teams will compete to… Continue

Minimum Blimp V2 update

As mentioned before, for the second version of our Minimum Blimp Jordi and I decided to mod a RC toy blimp on the grounds that it will be cheaper and more robust than trying to build the whole mechanical assembly… Continue

UAV Project Progress - flight gear simulation, first steps



I am working on using flight gear to simulate and test my UAV code. The screen shot shows flight gear and the C# application that is receiving the data. the way I see it, the first step is to read some data out of flight gear. I am using a TCP socket to read the data. I have achieved display of the raw string of data. My next step will be to parse the data into meaningful bits. I have been looking all over the net for information on using flight… Continue

Autonomous UAV Aerobatics Project



here are two notes below that describe the fantastic video demonstration of the MIT Autonomous Airplane Indoor Flying test. Keep your eye on this page for more info in the future.



"In these flight tests, a fixed vertical landing platform was designed and attached to a concrete pole in the middle of the RAVEN flight space to allow the fixed-wing aircraft to land and perch on the pole.… Continue

What does "Open Source Hardware" mean?

Here at DIY Drones, we adhere to open source principles wherever possible. That means we aim to share (that means post it, not make people ask for it) code, schematics, PCB files, parts lists, instructions, and algorithms for every project featured here. In practice, that's not always possible (not all… Continue

A clever approach to indoor beacons: ultrasound + IR = GPS

A Luxembourg-based team has come up with a really clever indoor navigation system that combines ultrasonic beacons with IR to achieve absolute position ("synthetic GPS"), much like the NorthStar system we use but entirely DIY.



As they… Continue

YARB 1.0 - added compass and ultrasonic sensors



I attached some additional sensors today - a pair of Maxbotics EZ0 ultrasonic ranging modules and a Honeywell HMC6532 I2C compass. Also, I added an extender to the camera module to point downward about 30-degrees and I finally adjusted the focus. I think the camera angle is pretty good now - the wide angle lens has a field-of-view of approx 120-degrees, so the bottom of the frame captures objects almost directly below.



I haven't yet filtered the sensor data. The… Continue

YARB 1.0 update - first untethered flight

Here's a video clip from YARB 1.0's first untethered flight. I captured the video while sitting in my office while the blimp explored the hallway and front room (the dogs completely ignored it). The camera is a bit out of focus, and the afternoon light washed out the picture somewhat, but you get the idea.



You can see the modified console with buttons to vector the props and invert the video. I'm actually surprised with how easy it is to pilot YARB - it is very responsive.… Continue

Prairie Predator Build

I've been working on a Nitro Predator for about a month and ahalf now. I'm stalled trying to figure out some problems with an Airtronics radio system I have that doesn't want to work. Everything "seems" OK but when I hook up servos to the receiver and try to control with the TX, no luck. the servos jitter when I apply power at the receiver, but no response at all to TX commands.



am playing with adding a controllable rudder to the Predator for no other reason than the real one has… Continue
