Okay guys,

Yes, I am cheap and like to stretch the almighty US Dollar to the last bit I can take it and found a super nice place that you can find "NEW" batteries for these older I-Phone 4 and 4S smart phones!

I purchased this used I-Phone 4S from a repair shop locally here in Orlando, Florida and bought it for the less than what it would have cost to fix one busted glass screen from an early Android Smart Phone . Can't believe this used I-Phone has lasted this long (2+ years) and has taken one of the best pictures and videos I have ever seen. The battery finally was not lasting like when I purchased it and I finally broke down and purchased a replacement battery kit!

From where? A USA seller at eBay, that's where!



I followed this YouTube Video carefully!

Hello everyone.
First of all thank you to all the answer and help you give me
I need help with the gsm hubsan h109 high edition. My problem is that the picht of the gimbal should be 65 degrees and -125 degrees, but in my case it's the other way around, focus more up instead of down. Hubsan does not give me any solution. If anyone knows anything I appreciate it beforehand. I'm sorry for the translation, in case it's not well understood.
a greeting

Drones will be used to assess Marawi city damage. The Lanao del Sur provincial government is planning to use an aerial drone to assess the damage caused by the ongoing conflict and identify areas needing priority rehabilitation. Vice Governor Mamintal Adiong Jr. said the capitol forged the drone mapping contract at less than 95 percent of the original price. The aerial mapping will really help assess the damage and what areas will be given priority in the rehabilitation phase.

I’m Dave, and I’m an RC. (Remote. Control) addict. Notice I did not say I’m a recovering RC addict, so that means I’m still a practicing, full fledged, not even hiding it RC addict.

Most addicts have an RC vehicle of choice….I’m no exception, my RC of choices now is mostly quads, and still occasionally my planes. While I’m addicted to all forms of RC, I started many years ago with Planes (for many oldtimers, this was the gateway RC ofcchoice, their starting point)…and like most addictions, in the beggining, mine was “for fun”. I was what is reffered to as a ” casual” RC’er , only doing it with friends, never alone or in private, and only on weekends, never during the week, and never exceeding my budget allowance. Then one day, the planes weren’t enough, they no longer filled the need, that giant gapping hole, and I tried Boats.

At first, Boats gave me that fresh high again, a renewed exhilaration. Then, like with the planes, one boat didn’t work any more, and I had to have more boats, and more. Soon I was caught in embarrasing situations because of my addiction, using my neighbor’s pools to run my boats, without their permission, while they slept at night. I had no logical explanation, I had to lie about my reasons for RCing ( “sweetheart, I only bought it because Paul did, I was just trying to keep him from RCing alone”), and I began to fabricate elaborate stories (“I missed work yesterday because my aunt died”, and the wake was at the hobby shop?).

And then there...Continue Reading

Like my Hubsans (which I felt needed a downward facing cam), I just thought a cam that recorded in 1080P would be pretty nice on my racing quad. I had a Runcam Swift 2 on it already, making it pretty darn easy to change over to this one since the connector is the same (and obviously, was already there.) So, I designed an insert to go between the quad and the battery to hold the PCB from the Runcam Split and printed it on my 3D printer. It fits between the battery connector at the rear, screws toward the rear of the quad and has enough room to not hit the FPV antenna. I glued it down with some Gorilla Glue since that stuff hold tight but you can still pry whatever loose (from carbon fiber anyway) if/when you feel the need.

It's funny that I've heard people saying that the Runcam Split has too much lag. Not mine, I zip through and around the trees with no problem at all. Also, some people have complained that it doesn't fill their 16/9 frame well enough. It works just fine on my Dom V3, my Aomway 7" monitor, and my Boscam 5802 monitor. Go figure, eh?

What the quad looks like with the Runcam Split and the 3D printed adapter

As a test for a future Nemeth umbrellaplane project I put a circular wing on a jupiter Scout fuselage. Great fun to fly but with strange controls:
Rudder gives great authority to roll control, aileron works like a rudder on a conventional plane, BUT REVERSED!
So I put Rudder on my aileron channel and aileron on rudder but in opposite direction.

So i took pretty hard crash the other day, my battery wires ripped off and ESC wires ripped off of pdb. I was too busy to fix it right away but after a week i got to it. After i resoldered all the wires back, i connected my battery and my esc's power up like normal and my reciever shows a green light as normal too.....but my FC's red light will keep flashing even after my esc's has done its little chime and motors wont spin up. Really need some help im pretty stumped

Boldclash bwhoop B03 pro Los flight indoors (0 min 50 sec)

I already have a couple of bwhoop b03 which are great, I have one in stock format which my daughter fly's and another which I silverised for acro flying.
This is the pro version which is actually cheaper ($17 at time I purchased it )and does not have altitude hold like the normal b03 version, this makes it more like the traditional whoop in flight characteristics and a lot more fun in my opinion, though the altitude hold was good for my daughter to learn because it makes it easier to start flying.

The other main difference is the frame itself which seems like it will be more flexible in a crash and so less likely the break.
In my opinion the colour is nicer too being grey / black rather than orange / white.
Bought here for $17 http://www.boldclash.com/boldclash-b...drone-p92.html
Very easy to get going with this out of the box it fly's really well, just charge it up via a usb socket and start flying.
It's very stable and VERY fast and responsive in highest rate ( tx has three rates which are nicely ranges from slow to medium and high ) probably due to the BIG motors that are used in these b03 quads, they don't get hot and I expect that they will last a long time unlike the smaller motors used in most quads of this size.
Using stock tx flips are possible in the usual way ie pressing a button at the front and then pushing the right stick in the direction required, they are very fast and tight and lose no...Continue Reading

Here is Anakin Skywalker's Jedi Interceptor ETA-2 from the movie "Revenge of the Sith".

The ETA-2 Actis-Class Light Interceptor Starfighter was built by Kuat Systems Engineering and a favourite of the Jedi during the Late Clone Wars.

Built as a helicopter due to the flight characteristics.

Unlike the Millennium Falcon which is essentially a cargo ship, being a fighting craft this one is much more agile so is classed as "Intermediate". She is a bit of a hotrod!

In the movie during combat, heat dissipating side panels were deployed. which can be retracted for normal flight. On the Phoenix model this is controlled with the Gear Channel.

R2-D2's little head rotates with Rudder input.

The twin Ion Motors at the rear are also animated so flicker and respond to Throttle input.


Based on a SketchUp model by dirx600.

Material needed :
- polythene flexible sheet (the one used to cover the salad in the vegetable garden will do)
- 60 gr/m2 glass cloth
- 120 gr/m2 glass cloth
- packing paper light
- a small piece of nylon cloth
- epoxy resin
- pure alcohol (the one used for liquors 95%)
- off course the wings with the shells
- an old fridge or freezer compressor (must be working) to be used as vacuum pump
- plastic to make a sealed bag and tape to seal it

Cut a piece of polythene big enough to envelope the wing (top and bottom) and make an invitation bent on the line of the leading edge (photo 1).
Cut a piece of packing paper like the polythene size.
Cut a piece of 60 gr glass cloth like the polythene size.
Cut 2 triangular pieces of 120gr glass cloth with base half the wing central cord and high 3/4 of the wing span (photo 2)
Cut 3 squares 1"x1" of nylon cloth

Now take the polythene sheet, place on it the paper and the 60gr cloth on the paper (no wax or detatching agent is needed as the epoxy will not stick on the polythene).
Mix the resin and the catalyst and dilute with the alcohol (40% about). For each wing in the photos I did use 12 gr resin, 5 gr catalyst and 6/7 gr alcohol. In my opinion it is better to dilute the resin beause it will be more fluid and you will need less resin to soak the glass cloth; remember that all the weight you place in this operation will increase the wing weight, whilst the alcohol will go away.
Now soak the whole surface using as less resin as...Continue Reading

I've been reading about the fancy carbon fiber filaments for 3d printing, and I just had to know if they were worth the money. So I bought a bunch of them, and made a 3 point bend test setup to see how they perform. I made a video, which you are of course invited to watch, and all the data is available on a google docs spreadsheet.

Vocab: specific ultimate strength is the force needed to break the material divided by its weight. Flexural modulus is how stiff a material is, independent of its geometry. Toughness is how much abuse the part can take before failing.

3d printing Fancy Filament Face-off! ( carbon filament bend test ) (7 min 31 sec)

https://docs.google.com/spreadsheets...91205013575002

In brief, the best all-around filament are the carbon filled nylons: the two I tested had similar performance so it's just personal preference. There is a graph below vs. regular PLA.

Runner up prize goes to the carbon filled PLA and HTPLA. I tested three types and they also performed similar to each other Not as strong or tough as the nylons, but significantly stiffer. Graph is below

Worst filament tested is the carbon filled ABS from Oo-kuma. it is not much better than regular PLA, and in many ways it is worse. Cannot recommend.

All the filaments tested are shown in the other three charts, sorted to show the winners and losers.

In general: adding carbon adds to a material's stiffness, takes away from its toughness, and leaves its strength unaffected.

I hope this helps you in your 3d printing endeavors!
