Martytoof, still looking for paracord? Dollarama is selling these extension cords for $3/1.5m. Several colours, you'd just have to junk the actual cables. Way more expensive than buying online probably but you can have it same-day.

If you're looking for actual accessory cord, you can get it for about 35 cents/foot at any climbing shop like REI or whatever is local rather than cannibalize a fabric coated extension cord.

Elendil004 posted:I still want to see a mass civil disobedience of everyone buying hubsan drones, crashing them, stopping what they're doing, calling the NTSB to report an aircraft crash and just completely swamping the system with bullshit. I'd say call 911, but tying up ACTUAL first responders is a dick move. Except of course the NTSB actually does have specific criteria for reporting accidents and unless your drone weighs 300 pounds, kills or seriously injures someone or is manned the NTSB doesn't want a report. Also the NTSB isn't part of the FAA and actually has a somewhat adversarial relationship with them, so punishing them for FAA rules seems silly. I suspect the registration is about being able to track down the owner after a drone crashes or is shot down, either with actual weapons or things like the Battelle DroneDefender (which I hope never makes it to the US since jamming GPS is a terrible idea).

Considering that even cell-phone jammers are illegal in the civilized world, gps jamming can't be allowed either. Besides it's pointless. GPS is convenient, but losing it isn't crippling to aircraft navigation. Even a lovely little cessna 152 is equipped with a whole suite of IFR navigation aids. GPS is more convenient to use than VOR, but if a whole bunch of assholes around me start putting up drone defenders, I'm just going to solder yet another sensor onto my flight drone.

One plane losing GPS isn't crippling to aircraft navigation. Every plane in the vicinity of rear end in a top hat McDouche who's firing off his GPS jammer is absolutely crippling to aircraft navigation (in the terminal environment). If somebody is doing that anywhere near a Class B airport poo poo is going to go crazy and the ATC system is going to seize up mega-hard. The fallback terrestrial systems have way, way less capacity than RNAV-based ones in terms of planes-landing-per-minute. As a pilot, I'd take a million drones over 500 dudes with GPS jammers any day.

The FCC would never allow that "DroneDefender" to be sold or used in the US; they won't even allow intentional interference on 2.4Ghz (see the relatively recent Marriott Wifi case) much less GPS. But the FCC doesn't regulate Federal users of spectrum, that's the NTIA. So the military and federal law enforcement may well be able to get them. A VOR isn't especially good for the types of flying drones do; it's basically meant to allow airplanes to fly along airways within 4nm or so of the airway centerline. I suspect you're radically overestimating your ability to receive VOR signals at the lower altitudes that drones fly at, much less the two VORs you'll need to receive to "pinpoint" (give or take a km or so) if you aren't going to put a power-sucking DME transponder on your drone. You're not going to be able use it to hover effortlessly like you can with GPS; it's no where near accurate enough.

I certainly don't. But even if the FFC goes bonkers and lets everyone put a jammer on the roof of their pickup truck, there's still going to be dudes who'll go hog wild with mouse sensors, sonar, lidar. Right now the only reason such technologies are important (to me) is because gps is not sufficiently precise for my requirements. If gps were suddenly unavailable, I would still fly, but I'd have to spend more money on more parts first. That's all the drone defender can do. It can waste money. It serves no other purpose.

Happy Back to the Future Day. After today, all of BttF happens in the past. If you'd like full size pictures: http://realtinker.blogspot.com/2015/10/building-150-class-quad-diatone-blade.html Well, there goes another handfull of cash. In the mail today, I got a package from BangGood. In that package was the following: 1. 1 - Diatone Blade 150: http://www.diatone.hk/goods.php?id=80 2. 4 - EMAX BLHeli 6 amp ESCs 3. 4 - Eachine 1306 BG1306 3100KV motors. In addition, on my bench, I have a Naze32, a camera, a 5.8ghz transmitter, a couple 3s 1000mah lipo packs, and a soldering iron. Annoyingly, the 6amp ESCs weren't what I thought they were. They were being sold on the same page with five other ESCs. Every one of those ESCs, excepting the 6amp one, were 2-3s rated. We'll get back to that though... Here's what I got in the mail:  At first I thought they didn't ship the airframe. I only found it when counting props and ESCs. The anti-static bag it ships in, is tiny. The airframe kit is quite complete. And it even comes with spare parts. You get almost twice as many screws as you really need, twice as many nuts. An extra plastic board standoff, and an extra main frame spacer.  I swear, that's my usual red work rag. There's a few more pictures like that. It seems my cellphone got it's white balance way off. One reason I bought this airframe, was that I was expecting it to have an integrated 5v regulator. Imagine my surprise when I found this PDB.  Well, I might as well use it. DIATONE recommends that the PDB is screwed directly to the lower frame. That setup seemed like it would leave the airframe wanting for space. After some digging through parts boxes, I found some standoffs. The PDB on my Blade 150 is under the bottom plate.  Oh yeah, we're building this now.  The Naze32 looks pretty comfy up there. It doesn't maintain that orientation... but I think that setup might be superior to what the quad ended up with in the end.  The lower arms mount on top of the lower plate. They have two post holes, and the bottom plate has slots for the inner bolts. This lets you set the arms at two lengths, with about 5mm between them. This example is being built with the shorter arm layout. And now we can make this convertable, a coupe.  It really set in how small this thing was. The red work rag doesn't really show scale. So here's a 18650 battery, and a 5x4.5 prop for scale.  The motors went on quickly. The 1306's look right on those tiny arms.  A quad this small, makes mounting all the components quite a challenge. I like to hard wire everything I can, so first there needs to be some testing. Alligator clips are essential in this stage.  It was also time to see if a hunch of mine was correct. ESCs are typically voltage limited not by their beefy driver side electronics, but instead by the accessories. The input filter caps, and the BEC are the big reasons for 1-2s, or 2-4s, or 1-12s, rated ESCs. These little 1-2s 6amp ESCs have a different BEC regulator than the bigger ESCs have. The LDO type vreg would fry trying to handle 3s and the electrical load from say, a servo, or a Naze32. That PDB with the 5volt regulator on it is just about to become essential for this build. By not plugging in the positive wires on the ESCs, I can remove almost all of the load from the regulators on the ESCs, hopefully allowing them to survive higher input voltages. ... They can. So they got installed.  Those are some itty bitty pads to solder to. The PDB needed to be tinned too.  I made a mistake. I should have soldered on the center taps first. But as you can see here, the positive leads for the ESCs were soldered first.  With the negative legs soldered on, it starts to look pretty busy.  Finally, the 12v and 5v takeoff leads were soldered on, and some wire management was begun.  That board got flipped over and screwed in place. Later on in the build, the bottom of the quad ended up looking pretty manageable.  Now it's time to go after the flight control systems.  At some point, I'll start caring, and start cleaning up my rosin. Today, is not that day. I've soldered the +5 and gnd from the PDB to the bottom of the Naze32. That way it won't need the BEC power from the ESCs.  The +5v wire from the ESCs were cut off, and not soldered to the Naze32. I need to figure out a way to make that cabling look cleaner. And lets not forget the CPPM lead.  Honestly, form this point on, it was a matter of just squeezing things in. For example, the reciever got zip tied to the top deck.  A little more stuffing later, and the Blade 150 had a transmitter and camera on board.  153 grams, isn't anything to scoff at. And 235 grams with a battery!  I've been talking about how small the quad is. Here it is sitting next to a QAV250.   The QAV seems like a monster in comparison. Sadly there won't be any flying tonight. The props I have hit the airframe. That really means I need to build a prop trimming rig. That shouldn't be a huge project, but it's not one to do tonight. I did clip two props, to see what it would look like with props on it.  I also need to wire up the harness from the camera to the VTX. There may also be some landing gear being built and an LED or two getting put aboard. The ESCs seem to hold up just fine under 3s use. The motors get a little warm, but being so tiny, they don't exactly hold on to heat very long. The ~3.5x4.5 props seem to be the proper size. I'be got some other ESCs that are rated for 3s use, that I think will hold up just fine for 4s. That'll be a fun experiment. Though I might replace the smoothing caps on those before I trust those to fly with. First flights should be this weekend.

Prop talk time. I'm buying some new props soon for my 250, and I'm wanting to up my game a little. I've finally gotten to the point where I'm not crashing every time I fly (just every third or so  ), so I'd like to get some more responsive props than the super cheap nylons I'm using. I started with tri blade ABS, and I noticed that my nylons are much more sluggish/floaty/mushy on my 250 compared to the ABS. I need some help fact checking and going over my thoughts. 1. Nylon glass fiber or nylon carbon fiber is where I want to be looking in terms of material that will make my flying more snappy. 2. Bullnose props provide more thrust at the cost of efficiency as compared to regular props. With that in mind, I think I'm going to get something like this: Gemfan 5" glass fiber nylon bullnose Am I off base here, overkill, better ideas?

So I found a drone race in my area and I'm going to give it a shot. http://usdra.org/2015/10/17/nh-techfest-race-in-one-week/ The only thing is that I can't find any talk about this at all other than the hype that the organizers have put out there. Nobody talking about it in Facebook or any forums. Gonna show up with my slampig 230 and see what happens  if any other goons are free/in the area maybe come and give it a shot. I'll also bring some fixed wing stuff in the event I can fly that.

I'll be heading out to this race near Hamilton. http://fpvracingevents.com/events/#fall I am very out of practice so it should be interesting. Hopefully they have enough daylight to run all the classes they have made. https://www.youtube.com/watch?v=HVeLpOCFxks The course layout has a really large vertical section so I bet that will eat a bunch of quads. Edit: Nerobro you can get same so much more space by hard wiring that receiver to the FC. This is a depinned D4r on a Naze32 on top of a small power distribution board.

I have a 250 quad that I'd like to retrofit from being a twitch racing flier into a more "robotic" feeling flyer with the more auto-level and auto-hold the better so I can fly and forget while I admire the camera view without constantly actively "flying" 100% of the time, if that makes sense. I was thinking swapping out the flight controller and adding GPS etc but maybe I'd be better off just buying one of those hubsans. Any recommendations for directions to go on this?
