Stuff has happened and stuff has arrived !

My solar power bank has been re-paneled and is outside laying in the sun catching rays .
Got stuff for the DLG , so hopefully get that CG where it needs to be .
2s balance charging board is here ...
Those magnifying bits of plastic are here .

F3 flight board .. its 1s and 2s .. I wonder if I will need higher voltage motors ?
Oh well , I will be doing some Multi meter readings and hopefully wont kill the board ...

So looks like I need a ROUND " To It "

Just working on a FuriBee H801 review at the moment ....

The following is a public service announcement !
I was on Feebay and thought about the Dumpster Brand batteries ! ( Dumpster Brand > Buy some batteries Throw them in the dumpster cos there so bad ) We all know feebay is flooded with garbage batteries , but I find pleasure in testing them just to see how bad they are . ( Rather than how good ) Have we seen the 9800mAh batteries ? ( 18650 ) Yeah there a joke , unfortunately people are buying them and then doing things with them they should not do . So lets get on with it ! I will discharge them ( well I did ) @ 0.5A , to 3v to see how much , or how little capacity is actually in these alleged 9800mAh batteries .

I got these as a pair , and the first discharge resulted in :

Battery 1 = 518mAh discharged ( yeah > thats 518 mA )
Battery 2 = 684mAh discharged ( Jaw dropping right )

2nd Discharge :

Battery 1 = 548mAh
Battery 2 = 682mAh

Would it be fair to say these are monumentally bad . Possibly dangerous , life threatening , absolute garbage that should not be for sale anywhere ? ( Would that be fair ? )
And so endith the public service announcement !

Review was made possible by FastTech AF link

The folks at FastTech have made it possible for me to review the Lumintop SD4A and what a nice light it is . Whilst I am a real fan of the single 18650 flashlight format I also find AA lights very interesting . Modern technology makes it possible for the average Joe Six Pack ( non flashlight enthusiast ) to safely enjoy powerful flashlights and the SD4A is certainly powerful . There is only one thing I can can complain about and that's the power output > it's too high !

The build quality is really excellent , actually from a mechanical perspective I have absolutely nothing to complain about . Everything works as it should , the fits are as good as they need to be . There are not rattles or squeaks , the clicky buttons are excellent . The SD4A is just a pure joy to use and being AA gives you the opportunity to play with a lot of batteries . So before I say anything else lets get to the performance :

Alkaline Batteries :

Low > 39 Lumens / Medium > 470 Lumens / High > 664 Lumens / Turbo > 900+ Lumens ( Output was dropping quickly )

Eneloops : ( nimh )

Low > 38 Lumens / Medium > 370 Lumens / High > 657 Lumens / Turbo > 828 Lumens ( Holding output )

Vapex : ( old nimh )

Low > 38 Lumens / Medium > 370 Lumens / High > 474 Lumens ... The SD4A kicked it down a gear here and as a result

Low > 22...Continue Reading

1) A USB 2s charger bundled with my JJRC H28
2) I purchased the B3 to see if it would balance charge as it is all over the place ( Ebay and such )
3) Bundled with a lot of quads n toys
4) Was bundled with a 450 heli combo

So , the question begs ... Do any of these actually balance charge ... ?

I discharged a 2s battery .. And using all the above chargers found no evidence what so ever of balance charging taking place .
I have used 3 and 4 in the past and found the batteries charged to be seriously out of balance .
No 3 being the worst offender .

So does a cheap charger exist that can actually balance charge ?
My guess would be (?) who knows .. I just use a imax B6 which does balance charge .
For a few dollars more then these nasty chargers a B6 will get the job done ..

I know a lot of people harp on the B6 and with good reason !
Myself , I am on my 2nd B6 . I ran the first up to 4 AMP charging 2200 3s batteries ..
And I was charging almost every day .. That poor B6 lasted about 12 months .. ( I did abuse it )

This 2nd B6 has not been taken beyond 1A for charging and might be half a decade old now ..
Anyhow .. This was about those cheap balance chargers that dont seem to actually balance charge .

Just before Christmas I came across some Ebay deals I could not pass bye ...
One of those deals was the JJRC H28 camera Drone ( or quad )

Two stand out features would be :
1) This quad is 2s rather than the usual 1s , it's also some what larger .
2) It has removable arms .. ( See pictures )

1) Battery :
That's right , 2s . I can't say the 2s give more power as it seems offset some by the larger size of the H28 and it's greater weight . The battery does seem to be a quality item , as I have not detected any variance worth mentioning ( seems well balanced / matched )

2) H28 :
The removable arms dont seem to affect performance . For now they remain tight and slop free .
The H28 certainly handles in a predictable and easy manner and should be noob friendly .

My only gripe here is as usual with the remote , it's a toy . The H28 quad itself could be considered hobby grade but just had to be bundled with a lower end toy controller . The remote is at best dead in the middle and vague when it begins to work . In nice open spaces it probably makes little difference but try being precise in a confined space and you will notice right away just how nasty the remote can be .

Binding the JJRC H28 to the iRangeX IRX4 multi protocol module .

As always , these toy grade quads perform so much better when bound to a real RC transmitter ..
I bound the H28 to my Taranis Q x7 with IRX4+ module .

I found the bind process a little tricky as the...Continue Reading

FuriBee F60 fitted to drone (1 min 29 sec)

Now I tried the H28 with its default camera and it sucked ! ( Sorry )

Anyhow I wondered if I could possibly mount and use a action cam .. The landing gear is certainly long enough to accommodate the action cam . So I took a windscreen mount ( for action cams ) , the shortest slider ( slides into mount ) and cam bracket / holder ..
Wow it fits ..

The mount is fitted to the battery cover with double sided tape , for extra security I also fitted two screws .
Looks to be a neat install .. Windy as all outdoors again so I did the jello test flight indoors ..

Cam is set to 2.7k @ 30fps ...

Yes there will be a H28 review !

I may have mentioned I picked up some bargains just before Christmas and the WLtoys A303 buggy was one of them .

Remote Distance: 50m
Type: RC Off-road Electric Car
Speed: About 35km/h
Charging Time: About 3 hours
Playing Time: 10mins
Car Battery: 6.4V 1000mAh Rechargeable Battery
Motor: 390 brushed motor
Brand: WLtoys
Material: Electronic components, Plastic, Metal
Remote Control: 2.4GHz Wireless Radio Control
Transmitter Power: 3 x 1.5V AA battery

The transmitter looks to be the same as the one bundled with the 12428 4x4 buggy from WLtoys .

The A303 is perhaps a little on the chunky side @ 938 Grams wet .

The A303 is almost as big as the 12428 ( Wheel base )

The 303 does sit a little low to the ground to be a true off road'er . I found the 303 was really dragging itself over the grass in our back yard . I would imagine this would really load up the motor / esc possibly creating heat and other issues . I would suggest this buggy might be ideal for flat dirt tracks / roads and such where the ground clearance would not be an issue .

I really like the turning circle on this one , much tighter than the 12428 . In fact I found it a little disconcerting at times as I over corrected ( having got used to the 12428 ) You can move the control rods so as to make steering less sensitive ( larger turning circle .

In fact there is a reasonable amount of tuning that can be done to the A303 to change its handling ( See Pictures )

I don't know that the A303 is in...Continue Reading

I think I mentioned I picked up some Bargains before Christmas ( The last of them came today ) ..
One of those bargains was a WL Toys A303 Buggy .. ( We are talking bargain )

Anyhow , the battery does appear to be a 2s 3.3v per cell ( Life ? ) ..
Well , there is no balance lead .. And checking after installing said balance lead , yeah ! There is a need for it ...

A) I unwrapped the battery just enough to expose the contacts ..
B) With your Multi Meter find the contact for the back or front of the batteries where they are joined for series .. On the MM this will show the individual voltage of each cell
C) Once you find the contact for the middle wire , solder in your balance lead
D) Make sure your solder joints are good
E) Re wrap the battery

I really like balance charging ( really I do ) . Not doing so can lead to all sorts of possible issues ..

Its not hard ! Positive and negative contacts are already a given .. Simply solder your Balance lead wires to these contacts ...
What is just a fraction challenging is finding a contact point for the series connection . ( Thats why you own a Multi Meter ? - Right ? )
So there you have it , another bush league mod !

2s Balance lead :

A lot of these have a black wire in the middle and a yellow wire on the outside ...
Just remember the middle wire goes to where the battery pack is connected in series ( no mater its color ) and the outside wires go to positive and negative where your power lead is connected . ( At least they use Red for the positive wire )

Before Christmas there was some seriously ( serious ) bargains to be had .
So good in fact one could not do anything other than simply hand over the money and wait !
And wait I have . But at last the WL toys 686k is here .
It be a simple 1s brushed quad with a plug in Wifi camera ( I will most likely remove it ) .

The advertised protocol for this quad is Flysky V6x6 ( Not mine )
This one is Q2x2 / Q222 ( just in case anyone has had issue binding to their IRX4 multi protocol module ...

Speaking of the IRX4 , I bound my 686 to my Taranis Q x7 / IRX4+ .
In menu 6 ( OpenTx ) I set the channel order to ( Works for me )
Ch1 = Ail
Ch2 = Ele
Ch3 = Thr
Ch4 = Rud

So when you first bind , be careful because if your channel order is out you may need to peel the 686 from the ceiling .
Might want to remove the props or hold the 686 firmly in your hand ..

Flying the 686 :

This is one stable and responsive quad .. Fully noob friendly with the factory Tx ( yes I tried it ) .
With the Q x7 everything was sweet except the yaw/ruder . It was slow / lethargic ...
I expect I will have to jack the rates up to make it a little more lively / responsive .
But seriously , for the money I paid , this is crazy insane value ...
If you have a itch for the 686 and you see it for good money , it is worth while having ..

Yes , I do recommend the 686 if you have an itch for it ..
Its Noob friendly , solid , and responsive .
The pittance I paid for mine , geez ..
Just don't know how they could do it .

My previous WL quad was the 959 and I think the 686 is actually easier to fly , more stable and more responsive to control input ( Fact Tx )
I can't complain about my sample , actually performed better than expected .

Was sitting here , and realized ... Hmmm can I run the camera from the 959 in the 686 ( ? ) I will have to check that

I got me a solar PowerBank some time ago and I always meant to pull it apart to see what made it go tick tock .

It does have issues :

a) Solar panel does not recharge
b) Parasitic drain

Anyhow , I pulled the SPB apart today ( 34deg C outside ) , and then used my MM to see what sort of Voltage and current the solar panel produced . To be fair it was weak . 3.237 volts and some 67mAh .. Sorry to say that is not enough to recharge a lipo .. If there is a dedicated charge circuit in the PB then it would soak up that power before any made it to the battery .

The parasitic drain would seem to be due to a LED Light that is always on ? ( For what reason ? )
Anyhow , I had a look on Feebay to see how much these panels cost and @ $1.75 Ozzi Bananas for a 5v 1W ( Claimed ) power output , I will actually see if :
a) The panel can live up to said claims
b) Actually make this PB work as a solar powerbank .

So I guess there will be a second part to this post when the solar panel gets here ...

Its hot , its windy .. ( Thats Australia @ Xmas )
Posted by old4570 | Dec 25, 2017 @ 02:13 AM | 1,817 Views
Its a nice day but the wind is up and a little harsh ...
So I was thinking whats on the back burner ...
The Eachine VR006 goggles for FPV sent to me for review by Banggood.com ..
I really was impressed by how nice they were , but there was this little focus issue ( My eyes are nearly 55 ) and I simply can not focus that far down . ( close )

So I opened up the googles and moved the screen about trying to see just where the screen might focus correctly ..

Right in front of my eyes is the correct position for a nice crisp / sharp focus .. There is no way I can move the screen there .
It occurred to me that perhaps some corrective measures could be taken ..
Replacing the original focus screen , or adding focus screen to correct my focus limited eyes ..
I get the feeling the focus screen needs more magnification for my eyes ...
So thats my project : ( I really want to enjoy those goggles )

While I remember .. I did shoot a email off the Eachine about it .. ( probably had a few by now ) .
As well focus screen in Ebay ( feebay to some ) , are some what cheap ... So I purchased a few different ones to play with .
Being plastic , one can always cut to size ..

With the mail fully snail , I hope to be doing experiments in the new year .

And all those cheap controllers ... + XK transmitters

Anyhow , I have owned and still own a few transmitters from the lower end of the $$ spectrum . Recently the opportunity became available to own the Taranis Q x7 which has been on my to own list for quite a long time .

I think its fair to say this is quite probably the most plush feeling transmitter I have ever owned . For some strange reason some actually complain about the gimbals (?) , I don't get it . On my transmitter they are simply superb , butter smooth and precise .
The very first thing I did on receiving my Q x7 was to see what battery solutions people had come up with to avoid using AA batteries . I personally find that NIMH batteries drop voltage too quickly so there for decided to seek another solution . There were a lot of interesting solutions on Youtube and unfortunately I found many of them to be problematic rather than viable solutions for me .

I went with a modified battery carrier and two 18650 ( I have a good collection of...Continue Reading

Bush League Modz ! ( Don't you just love them ? )

Here is one I just did today ...
I just love my DrillPro ( http://old4570.com/stuff/drill_pro.html ) = Review on my web ..

Anyhow .. The only thing that really was a bummer about this motor tool was the US plug ( Sorry guys ) .
And once I really came to the conclusion I loved this motor tool , I really needed to cut its plug off !

Once the plug was cut / butchered / removed I then cut and trimmed the + - wires and tinned them ( Solder )
I then screwed in the wires and put some electrical tape in the lead so as to be able to fit the plug cover firmly onto the lead and use a zip tie to hold it in place .

And if that sound easy , it was ! ( A seriously bush league mod )

Now my motor tool has the correct plug on it and we can live happily ever after ( ? ) ....
But seriously , this is one awesome motor tool that deserved the right plug on it ....Continue Reading

I am still trolling and saw some really good prices on wings at banggood . https://goo.gl/t5FsLn .
The spirit 600 was about $21 USD and the spirit 500 about $17.50 USD

Also BG is having a Christmas FPV sale https://goo.gl/RQ9jxL

Those wings make for some good cheap fun ..
I am still waiting for the day BG puts out a BNF version ( That would be so cool )
A sub $50 USD BNF wing

I tried FPV ( quad copter ) for the first time .. Its a lot of fun .
I just need FPV goggles that my eyes will focus on correctly ( fault of my eyes )
The ones I have , I just can't focus well enough and I am bumping into a lot of stuff ..
I also have a LCD screen for FPV , this is good , but I am striving for a sense of depth .. ( Why goggles are so good )

Anyhow .. The other morning we had a fantastic RC morning / amazing really .
So I pulled out my Eachine H8 mini and had the best time ..

So this fired up my RC neurons .. And I played with my RC buggy ( WL toys ) that was sent to me by banggood.com for review ( Thank you banggood )
I had a ball with the buggy .. ( wind was up by now )

Anyhow , this reminded me of the FPV experiment I tried with the buggy .

Now over a year ago a friend gave me a FPV camera and LCD screen receiver for said camera that came from a quad he had .
So the other day I had just removed the useless internal battery and installed a plug for an external battery ...

Anyhow 1+1 = 2 ( or an idea in this case )

I thought this cam might just fit my buggy just right
And it did ...

All that was needed was some zip ties , and the cam hooked up sweet .
Just wondering if hot wiring will activate recording or fry the cam ? ( Cam has a Micro SD card slot )
Anyhow enjoy the included pictures ..
Might be time to go outside and give it a try ...

Ok , I bound the XK X6 transmitter to a futaba Rx micro quad ...

A lot of folks might wonder just how you would go about that when the Tx has no bind button .

Apparently the XK transmitters go through a quick bind process when you turn them on .. ( remember this )
So take your Rx , and get it into bind mode .
Then turn on the X6 or X7 transmitter .
As the transmitter boots it will go through its bind process and bind with your Rx .
Turn of the Rx and turn of your X6 / X7 transmitter ..

Now you have to turn on the Rx first , then the Tx just like with a lot of micro quads N stuff ..
If you turn on the Tx first , you will not get a bind . ( Because the Tx needs to go through its bind process on starting )

So there .. ( Hope this helps )

Hmmm , Yep ! ( I blame those sales )
I got me a XK X251 ( See Pic 1 ) , but this post is not about the quad ! But rather the battery and charger it comes bundled with ..
As well I am becoming a little disillusioned with many of the reviewers that are sent product on a regular basis .
So I will just have to take on the roll of the DEVILS advocate ...

If you look at Pic 2 you will notice the battery only has a balance plug , and the supplied 2s charger ( Pic 9 ) does NOT balance charge .. In fact it does a horrible job of charging and I would rate this charger @ POS ( Pic 9 ) . The only other charger I had capable of charging this battery is a half decade or more older charger that came with one of my first 450 heli bundles ( Pic 10 ... and yes it was on special ) . Now this charger also does not balance charge , but does a better job than the supplied charger ( Pic 9 ) .

I found the situation some what intolerable so decided to add a plug so I could charge VIA my hobby charger ( Pic 8 ) . The first thing to do was get out a sharp ( Thats very sharp folks ) knife to peel away the coverings of the supplied battery ( Pic 3 ) . What I had to do was get to the positive and negative terminals so as to solder on a plug . ( Pic 5 ) Generally I dont throw away plugs , I sort of collect them for just in case circumstances ( like this one ) . Pic 6

Pic 7 shows the completed job . We all know how to solder and we all know not to short the lipo ( Right ? )...Continue Reading

Christmas ( Xmas for some ) is creeping up on us , rather uncomfortably quickly to boot .
This year I took advantage of all these crazy sales ( some may have noticed ) and the Bugs 6 is what I got my brother . ( Yeah it was on sale )
Came today , so it's currently wrapped and parked next to the plastic Xmas tree .
I did take a peek and it does look like a quality ( plastic ) quad .

Maybe after Xmas my brother will let me play with it ?
