Cory Arduino GPS shield with SD card logging.

I saw this yesterday over on the Make blog. Adafruit has come out with a new Arduino shield which looks excellent for UAV usage. The shield has support for several gps modules, and can log data to an SD card.

Even with the GPS and SD card, there are still 5 digital and 5 analog IO op… Continue

Brian Most Bang for Buck?

Your opinion is welcome... Regarding our common goal of getting UAVs into the air doing the job they are tasked to do, what starter kit provides the most bang for the buck? Basic Stamp (usb) or Ardunio Starter Pack? Did anyone start with either of these two setups? Were they worth it? Were the included 'projects' teach you anything worth while? Do you recommend one over the other? Is there another starter kit that you'd recommend instead of either of these keeping around the $80.00usd range?… Continue

Chris Anderson The problem with neural networks

This, from the always interesting Jack Crossfire blog, is the smartest observation on neural networks and genetic algorithms I've seen in ages.

That fiasco has cursed all future investments in the radically different genetic approach. The genetic ap… Continue

Since i already did the Goals List in the last one, this will be the materials list This plane will use solid wireless broadband to accomplish the goals of flight control uplink and video and sensor output downlink There will be no receiver.

rad man UAVs for profit.......or development

As many of you know, the price of commercial UAVs are through the roof . Right now is a great time to sell your uavs. They're cheaper than commercial uavs so they will sell easily to anyone who wants a UAV. The point I am trying to make is not for prophit but for devlopement. So we can make bigger, better, and more powerful UAVs. Continue

Jack Crossfire XBee price increase

XBee Pros have been raised from $32 to $36. Feel like a fool for not buying more at $32, although the direct store still has some. Still have 2 $32 modules from last year. The higher priced model is the XBee ZB ZigBee PRO Series 2 supporting "more dense mesh networks". Maybe it even has Techron to clean your speed controller. In 5 years these obsolete modules will be $65. Should buy some paperclips. The next bull market is paperclips I tell U. The good news is a new 900Mhz module has appeared… Continue

Its been 8 months since my last post and i'm back to UAVs again. this time i have project funding, so money will not be as big of a project halter as it was with the last one. I am still learning Stamp BASIC programming. I've spent my time learning to fly the heli though. I intend to use a propellor board as my heli's main processor. However, the Prop board leaves a lot lacking. I am into SBCs and big computer calculations, not these microprocessor mini codes. Therefore, when i won a nice Boser… Continue

Howard Gordon simple VTOL airplane with vectored thrust

I just ran across this on Yann LeCun's blog - Yann is a professor of mathematics at NYU, a leading authority on neural networks, and an R/C enthusiast. This is a conventional airframe with two sets of vectored motors (similar to what we're doing with the blimps). Yann reports that two rotors turn clockwise and two counter-clockwise on a diagonal. Stabilization and control is accomplished with a combination of conventional gyros and channe… Continue

Jake Lancaster Icarus

Hi Well, this post is about a pet project i've been cooking up in my head for the past few months, but have lacked the tech knowledge on how to go about it much more than a few diagrams on the computer and my own imagination. What i've been wanting to build is a hybrid of a semi-rigid blimp and helicopter, with a long length of flight time, good manueveribility, but with speed similar to a RC plane. My first idea was a blimp with their long flight times since very little power is needed to keep… Continue

Aaron Weinstein first blimp concept

I'm trying to create a blimp with ~50" envelope that can follow a moving target (a person) in a large open area with presumedly standing air conditions. going to plan this around the arduino board Initial worries are: -the velocity of the target (this can be controlled to some degree, ie: area has distractions) -lag time of blimp will play a big part. Am thinking of integrating a buffer zone around target. -tracking system. I'd like to use active RFID (… Continue

Chris Anderson A simple demo of how to read RC signals and drive servos with Arduino

Most autopilots have the ability to read signals from a RC receiver and drive servos. For instance, in the case of ArduPilot, we read the current throttle setting when the autopilot is engaged (so we can maintain that setting, although we'll later nudge it up and down to maintain altitude) and we drive the rudder servo and ESC. In the case of BlimpDuino in RC mode, we read the throttle and left/right commands from the RC receiver and translate them into commands to the motor drivers (the vectori… Continue

Brian Twin motor setup

I've been contemplating about different platforms that could be used that, to me, seem a little more UAV'ish, but I've noticed that I have not ran across any twin motor setups within this site. I've poked around quite a bit, but certainly have not read every page posted. Is there a reason for not utilizing twin setups? Is it simply a matter of scale and payload to flight-time payoff? It seems to me that a few very good possible setups include: OV-10 Bronco http://www.nitroplanes.com/yetwenovb… Continue
