1080 HD so you need a big monitor... 1920 pixels wide. 200mb


Testing when getting a bit dark, over the pond in the park. Makes me very nervous...

[Seajays]

Bm, your video is screwed up, only download about 8 seconds then stop, then tries to load more than back to 8 seconds and no more video. Others of yours did that too.

[Burgerman]

Works fine here. Also from the pub on laptop... Its your connection. But from Canada I am surprised you get 8 seconds! You need to be streaming 200mb in 1.5 mins smoothly without a break! That's cont 2.2Mb per second across the planet...


Download to desktop and then play. 200mb, it wont stream without very fast connection as its full 1080p HD (1920 X 1080 pixels @ 30 fps)...

[Seajays]

Nice video, but no Babes

[Burgerman]

Its 2 degrees C so about the same as my fridge!

And almost dark. For some reason the vids look like daylight.

[rollingcowboy]

why do you risk flying over water?

[Burgerman]

Because I can. And because my friend in the pub said I wouldn't do it. And because I have to get over the fact that if anything fails in future its going to go down over a town or whatever at up to a couple of miles away flying by FPV. And lost. As soon as my video goggles arrive.

Its hard to do because of the money and setting up etc.

If you love it you have to let it go. If it loves you it will come back!

Big altitude mountain climbing. TAKES Three batteries. And about 35 mins climbing.

Wind, cold, panic, over Niagara falls, but comes good in the end... Not Black Sheep. Amateur (very cold one.)

Venice - new yesterday. Looks like a nice colourful place. Full screen is a must!

[MrSpudboy]

nice vid.

Kids, huh? It didn't have anything to do with the lathe in your bedroom?

[Burgerman]

Its not my vid. So no. But I made prop adapters, but that's it. You can buy them though.

For anyone interested in RC or extending the Hobby RC transmitter range. I just changed the max range from my JR 12x Transmitter from about 1 optimum, often less to about 4 miles.

By fitting a 2000mW WiFi booster. It allows normal operation, is dead neat and tidy, and gives exactly 12dB of gain using the same antenna.

That quadruples the range, as it transmits at 2000mW rather than 128mW. Now I can fly MUCH further away, with my quad copter, and up to around 4 miles high with my gliders... This is of course all illegal, but who cares. And at least twice that, with a high gain antenna!

[Lord Chatterley]

Have you polished that too?

LC

[Burgerman]

Of course. I do it to everything. Even the booster had its bolt hole mounting cut off, Filed, cleaned up and reassembled and the RC transmitter was stripped and rebuilt super clean.

That RC transmitter is all magnesium casings, back and front. Comes apart like a gun, everything just fits. All the bolts are now stainless polished too! OCD.

Shapes.

Strange word if you keep saying it, it starts to sound odd.

How's summer in your area? Here's my street from about 100 feet. Today. Windy, cloud, and sun all at once. Every-ones gardens are green from the rain.

Shapes is the song. My neighbours are used to seeing this come and go now. I can now do about 4 or 5 miles range all over the town. This is just my street though. Download to desktop first or it wont play as its too high bitrate.

http://www.wheelchairdriver.com/gopro/shapes.mp4 movie, just 3 mins, 250mb. This is the low res 720 version. Its part of an illustration for a web page. so is covered in text.

The 1080 one version is HUGE and very detailed. No text.

What great coverage of your booster installation... thank you and very nice work. I have a question if you don't mind. The JR12 radio is gorgeous but more than I can spend. I'm working with a Walkera Devo 10 and it has selectable output power (1,3,10,30,100, 150mW) Do you think I could use a lower power setting instead of using an attenuator?

[Burgerman]

You could.

It all depends on which booster. They all have a max input level quoted. And to get full power you have to be right on it, but not over it.

The booster is linear. Meaning if max input is 100mW (20db) and you feed it exactly this you get 2 watts of power out.
But feed it 50mW and get only 1 watt out.

The difference is 3db in power level. 6db will either half or double the range.

So you need to know the real specs of booster and transmitter. Your quoted figures will likely be RF out, not electrical power level. So if like mine it has a 2.3db gain antenna you need to deduct this to get the electrical signal power output.

Feed it too much and you get 2 problems, distortion, and failure while flying...

[TerryP]

Thank you. I have a background in electronics (a lifetime ago )) but I have very little knowledge of RF stuff. I've ordered the same booster you used but I doubt if I can get any specs on this Chinese radio. I'm already not happy with Walkera. The main board in the TX has a resistor missing so channel 10 doesn't work and they won't do anything about it, even though I sent them a picture! I won't be buying any more of their products. It's amazing that they would loose a customer for the sake of a tenth of a cent resistor and a two dollar stamp! Anyway, I'm stuck with this one and I'll scare up a 100 ohm smd resistor and solder it in.

I'm sure the power ratings are rf out. Does it make sense to assume a gain of 2db for the antenna and set the output power to 100mw which it would leave me with 18 db into the booster? If this is right it would cut range a little but keep the booster safe and still increase my range considerably.

[Burgerman]

If they stick to the rules, and you have a short typical TX antenna, then yes. The transmit power will be 17.8db, and the booster wants whatever they say maximum is for the one you buy.

[TerryP]

Thank you very much.

[Burgerman]

Easy test. Use a stock transmitter, fly plane/quad away, watch distance in goggles and failsafe will kick in at say 1 mile. Land.

Do the same ON SAME DAY, with the 2 watt boosted transmitter, (3.2 watts radiated RF) and get 4+ miles and its working properly.

Each 6db gain - double range and 4x electrical mw power.
100mw = 1 mile. 20db output.
100mw x 4 = 400mw = 2 miles. 26db out.
400mw x 4 = 1600mw = 4 miles. 32db out.
1600mw x 2 = 3200mw = about 4 x 1.333 or 5.3 miles. Another 3db out so 35db total or a 15db gain...

So you should really get about 5.3 times the range. (4 to 6 real world reliable testable LOS miles plus).

[TerryP]

We still have 2 feet of snow here but if spring ever comes I'll do the test. Thanks again!

[mous3]

No, women are hard work. And unfathomable, confused and never happy. And I am 53 and still dont know which way up they go.

And babies! No thanks. Rather stick to my helis/multi rotors/gliders and bar wenches...

I agree totally with the above. Except for the never happy part

Hi, I have looked at the page on the JR 12X DSMX and booster conversion. It is an excellent article and just as what I have been looking for years. I have a JR 12X non-module transmitter and would like to convert it to use Weatronic transmitter module. I have an 12X MV (module version) and all I needed to do was to unplug the 72Mhz module and insert the Weatronic module into the slot. I have asked many people if I can do the same on the 12X non module version (it is still in DSM2 BTW). All people I have asked said it is impossible. The Weatronic uses the PCM signal from the JR 12XMV. I am wondering if the PCM signal is also present on the 12X non module edition once I remove the cover and the original DSM2 2.4G PCB? The two rows of pins seem the same as the 12XMV.

Thank you in advance.

Yes. You need a PPM based module first, 72, 35mhz etc, so that you can choose PPM mode, (PCM?) (then plug in your module. You will lose some higher channels I think.Not sure.

There is no difference between the two transmitters other than: The antenna and its cable, and a plain rear cover.

The DSMX or DMSS (module) or the board from it, with a 2 watt booster and 3200mw RF is far better than weatronics for signal security and range. But not technically legal. Weatronics + booster would give about 8 miles range or more due to sensitive receivers.

Also has at least as good range as the JR EZUHF module. That wont fit anyway! And more "interference" proof. UHF better through hills and walls though.

[hon]

Thank you for your explanation. Is this the same booster that you used in your conversion?

You talked about signal security. Did you mean dsmx has better signal security than weatronic even before boosting?

Thank you again.

[Burgerman]

The casing and specs are the same. Mines a BlueSkySea one. Seems to have a much higher output than the 2.5 watt and 2 watt Sunhans one. So while I think that one may be the same, I cant tell without trying it.

I know these are OK.
