Xboard Relay - Nightly I made the subject about the cable because the cable is key to connecting more than one shiftout module. Most shift register boards do not take advantage of the carry out bit or the serial output data. The DFR0072 Shiftout Module has a whole connector, and cable made for this purpose so it’s very easy to cascade them mechanically, but I haven’t found any good software that supports 16 bits of output for two cascaded Shiftout Modules. So here is some software.First an example of a basic shiftout scan with 8 bits one shift register. Just to understand the code.[code] /****************************************************************************** Test Program for the 74HC595 Shift Register in the DFR0072 ShiftOut Module8 Relay Scanner The DFR0072 ShiftOut Module has 6 pins:(1) SCLK (2) +5V(3) iCS (4) +5V(5) DIN (6) GND made by peter@testelectronics.comJanuary 08 2011******************************************************************************/ #define PAUSE 200 [/code] [code] [/code]...
wiseman/mavelous · GitHub - Nightly Augmented reality display of air traffic for amateur drones — Lemondronor - Nightly Each black square shows the location of air traffic. It displays the callsign (if they're broadcasting one), the ICAO identifier (the unique 24 bit ID assigned to every airframe), speed, altitude and distance. A few things to note about the video: I calibrated the drone's compass (webflight has a calibration command), but there was still some drift. This demo overlays aircraft on the drone's first-person video in a ground control station, but there are other ways the ADS-B data could be used: Augmented reality overlays in first-person video goggles. For details on how to try the code yourself, see the webflight-traffic github repository .
AR.Drone WebFlight - Nightly Pilot the AR.Drone 2.0 directly from your browser. Extend the application with plugins to add features such as video recording, autonomous flight, face recognition, and more. It makes it a very friendly environment to quickly build and experiment with your drone (e.g. during a nodecopter event). Built-in plugins video-png stream the video to the browser through static image loading, works great in every browser.video-stream uses node-dronestream to stream the raw h264 video feed via webscokets and rendering in Javascript. Additional plugins If you have written your own webflight plugins, please add them to this list by editing this page. copterface detect faces and track them by rotating the drone. Install WebFlight requires a recent nodejs (built and tested with node > 0.10) as well as npm and bower for dependency management. git clone git@github.com:eschnou/ardrone-webflight cd ardrone-webflight npm install bower install Usage Remote control Use Z, S, Q, D to move front, back and sideways.
APM2RC - arducopter - Arduino-based autopilot for mulitrotor craft, from quadcopters to traditional helis - Google Project Hosting - Nightly Wiring up the APM board is easy. Just connect your RC receiver to the Input side (using the special cables that came with your quadcopter kit, or just any female-to-female cables). And then plug the signals cable from your power distribution board to the Output side. Please note the illustration Below highlights a (TYPICAL) installation. WARNING:The diagram 'Typical QuadCopter Layout shows the gimbal servos connected and powered by the 5V coming from CH10/CH11. Note: the instructions below are for regular RC receivers with PWM output (one cable per channel). The order of pins is shown here: The ground (black) side of each connector should be on the outside, closest to the edge of the board, as shown here with either straight or right-angle connectors: If you're using the multi-pin connectors that come with some ArduCopter kits, connect them like this: Input Output Note: B = Back Motor, F = Front Motor, L = Left Motor, R = Right Motor in + configuration.

RC Groups - View Single Post - APM 2.5 / Ardupilot Mega / RCTimer Arduflyer Discussion Thread (updated 5/8/13) - Nightly Pay attention, here comes an interesting finding which may not mean a lot to some. NORMALLY - 3DRradio does NOT work if USB is connected to ArduFlyer. However there is a way to power ArduFlyer using a USB cable AND have 3DRadio working. Trick is to use the USB cable to only supply 5V power and NOT make an actual USB connection. How do you achieve that ? Connect the other end of the USB cable to a phone charger with a USB connector outlet like this one from HTC which can supply 5V 1A, ArduFlyer only needs about 250mA 3RDadio works, no need to remove props or use a different BEC and Lipo, normal UBEC and ESC can all remain connected quite safe. It may also be useful when tinkering with ArduFlyer in or near a car or any battery, as there are car USB chargers that output 5V 500mA with input rated at 12V to 24V.. Having a short extension USB cable built into the frame seems like a good idea.
PPMsumRC - arducopter - Arduino-based autopilot for mulitrotor craft, from quadcopters to traditional helis - Google Project Hosting - Nightly on FrSky receivers called CPPM PPM and PWM are two different protocols for radio information. The PPM has the advantage that you can get all the channels information through one port only. Also you can get extra channels. On both the APM1 and APM2 you can use PPM input by putting a jumper on the RC inputs for channel 2 and 3 (just the signal pins). Please note that Arducopter 2.8.1 and earlier versions required you use a transmitter/receiver combination that outputs at least 8 channels of ppm information. In order to use PPM-sum on APM 1.x boards you may need to update the PPM encoder firmware. PPM encoder for APMv1.x. PPM encoder for APMv1.x.

FRSKY's CPPM at 27mSec - Firmware update with FT_Prog and FTDI cable - DIY Drones - Nightly Introducing the Issue and the solution: We've talked about FRSky's CPPM signal on this other post that compares it with a standard PPM signal. The issue is that originally FRSky's CPPM runs at 18 milliseconds. That short period has no space enough for 8 channels plus a proper sync pulse. After carrying that issue to FRSKY, Jani came up with two FRSky's beta firmwares running CPPM at a 27 milliseconds period. We did test it at the DIYDrones Dev Team and it seems to work pretty fine. Some guys at that old post were expressing their worries about the 37Hz update speed from the new custom firmware. Well, now those beta firmwares became official: There are custom firmwares for the receivers D8R-XP and D4R-II on their Beta Test Section . About the Updating process: Inside of each update zip file there is a PDF explaining how to update your receiver. Reading their manual you'll see that an FRSky USB cable is necessary. How to use an FTDI cable: Now click on the "flash icon" as shown below:
The APM 2.5 Board Overview | ArduCopter - Nightly Table of Contents The APM 2.5 Board Overview The APM 2.5 board requires no assembly, and is ready for firmware. You have a choice of side or top entry pin configuration, in order to accommodate a variety of installations. You’ll see this option when you order. ***Click and drag the image above to spin it! This page will give you a look under the hood, and go into more detail about the design of this board. APM 2.6 is a revision of APM 2.5 for an external magnetometer (compass). Details APM 2.0 Details APM 1 (This page is still under construction) Like any computer, the APM needs a power supply with a steady clean voltage and sufficient current. 3DR provides an APM power module that supplies 2.25A at 5.37V. If you are using any servos such as are required with a traditional helicopter or a camera gimbal, you will need to provide an additional dedicated power supply for the servos. In order to design a power supply for your APM, you’ll need a basic understanding of the power circuit in the APM.
Mochaboy's blog - RC Groups - Nightly Fastest build to date, and I have to say - I'm love love loving this frame. The clean/dirty plate concept was enough to isolate vibrations from a chipped prop and out of track prop. Money well spent! It's a lot of work to put these up in the air, but when it comes together...boy does it come together Sit back and enjoy the ride. I'm an APM guy, but I'd heard about the CC3D, and just like any other fabulous piece of technology - it's unavailability makes it just that much more desirable. It was just a PCB board with 2 pigtails. I'd seen the curious inventor's instructional videos on how to solder SMD parts but it's just like anything else - they made it look so deceptively easy. Mistakes will be made and you will need the right tools to back out of those issues (i.e. solder braid and flux to wick away solder bridges), but the trick to getting through is proper planning, the right tools and lots of patience. Anyway - enough hot air - enjoy the show! Maker's kits available HERE ... Enjoy
