Thanks to the good ideas of Gary Mortimer and others, we're now launching a Trust Time Trial contest. The idea is simple: you set up four waywaypoints, spaced 200m apart, on your own field and time your UAV completing the course. Upload the data in the comments here. Best time on Sept 1 wins (I've got a prize this month--a new… Continue
I just recently moved over from NXT to Paparazzi and I must admit I'm amazed. Excluding some problems with my radio equipment it was really easy to get flying fully autonomously; just earlier today I got everything plugged in. As the airframe I used one of my EasyGliders. It has AuW of 1,4kg and about 400W brushless setup. With it I'm using a 2.4GHz radio which… Continue
I've never introduced myself so I'll take the time now (feel free to skip this paragraph). I have a business background but I am a technology enthusiast. Recently my interest about the business and strategics/social aspects of Open Source (especially Open Hardware) has really grown. In order to better understand the OS… Continue
Gary Mortimer has a good idea: a DIY time trial contest, where you time your UAV flying autonomously over an agreed-upon course. You upload GPS track, time and, onboard video. Fastest time each month wins something cool that I'll donate (like a Funjet kit).
What kind of course would work best for this? For starters, how about this: a square, 400m on a side. Must complete three full circuits in… Continue
Now that I've completed this major milestone in my research project, I'm switching gears. I've ordered the ArduPilot with the goal of autonomous flight by the end of August, in addition to achieving other, more classified… Continue
I'm installing Ardupilot in the 6 foot wingspan electric Telemaster. As this is a significantly different airplane than the Easy Star I want to proceed slowly and carefully. If I can I am going to adjust and confirm PID settings, etc, one function (roll, climb and speed) at a time, starting with roll. I decided I needed to have a good idea how the roll software is implemented in Jordi's and Chris' marvellous software. So I embarked on developing the functional flow diagram shown here. It is… Continue
Hello everybody! I would like to introduce EasyStar (with a few mods) UAV which uses PIC32 based autopilot that I've been working on for a few months (started a few weeks before Brian Wolfe showed his work on DIYDrones ;-)
Right now it's build upon UBW32 board but in the future I plan to desing my own PCB and decrease… Continue
This is just a repost for those who are new to ArduPilot:
Here's a very simple Arduino program that will test your XY and Z sensors. Just load it on ArduPilot (make sure the board is powered and the GPS is not connected). With the FTDI cable connected, click on the serial monitor icon in Arduino and make sure the speed is set for 9600. The program will prompt you to tilt the… Continue
I posted on here a while ago that the wii motion plus gyro sensor had been cracked but didnt really get much buzz about it. Well one problem with using the M+ in addition to the nunchuck to supply the accelerometer is that both are on the same I2C address. I found a real easy way to get around that problem and now the possibility opens up for a $40 6 sensor system. Now, I love that diydrones is offering an IMU system now to play with, but being a poor college student I cant shell out over $100… Continue
Well my back ordered parts finally came in so I built up my last three PicPilot boards. I plan on keeping one of them so I'll have two to play around with. One is in my Tri Rotor and the other will be installed in the Easy Star clone I just received. Of the remaining two, I have one potentially sold leaving one up for grabs. If your interested the cost is… Continue
We have a UAV device that can stay on the air for up to 50 mins, runs on clean energy, and supports a payload of 8 lbs. Talking to some companies that sell video to real estate companies, it seems they would be interested in a device like this because it competes against helicopter. The only concern from the people we've interviewed, is stability. I still think there must be something out there to mitigate this concern, right?
Do you have an unused PC lying around somewhere? Try ripping into your old desktop for its power button! My Thermaltake Soprano yielded a nice looking power button with a two-pin female connector, perfect for plugging right into the ArduShield.
