The 1st drive in the city was awful. The radio has had growing pains, as it has been driven farther. It 1st started dropping out when near a phone tower. In the city, phone towers are a lot more common & the radio was all over the place. Never had this problem with the higher power 900Mhz radios. The lower power 900Mhz radio is no match for phone towers. It's surprising how frequency hopping made no difference. There's not enough room in the remote for an XBee.

There are other single chip radios besides the MRF49XA/SI4421. Antenna placement is not the best. They're bundled with a lot of other wires. Another idea is creating a phone app to make the spectrum analyzer portable enough to find out what is jamming it.

In the apartment, the spectrum analyzer shows it neatly divided into 9 channels as programmed. It's hard to believe anything could jam out all 9 channels. There are still a few blips when it's off.

Lions aren't very enthused about creating another phone app for test & measurement. Goog has clamped down more & more over the years on what apps are allowed to do. Out of a growing desire to have more control than Goog allows, there's a growing desire to fabricate a portable confuser out of a single board confuser, bare LCD panel, bare keyboard & touchpad. The single board confuser would be standalone inside a brick. The keyboard & monitor would be in a separate clamshell, either connected by wireless to the confuser or some kind of dock, but it wouldn't be transported in 1 piece like a laptop. It would be a 2 piece laptop.

Hehehehehe Believe it or not !

Yeah , thats a hotgucam .

Short Story Time .

I got me these ELE cams a long time ago when they were like all the rage ! The all black cam suffered a LCD fail , as in it simply stopped working . But the cam recorded video just fine , I just had no LCD image .
Recently the other ELE cam has started corrupting video ..
Its a dull - windy Saturday afternoon - so what to do ?

I know , I will butcher the corrupted cam for it's LCD screen and also to see how the cam is ass-embled
Having removed the LCD screen from the corrupting cam I did a LCD swap ..
Black cam now has a working LCD screen , but .......

Was the original LCD screen faulty ?
So I plugged it into the now some what FUBAR ELE cam to see if the screen worked ...

Oh yeah , it worked ! What a terrible dilemma , the FUBAR cam might actually still function ( ok it was corrupting video ) . But it is a dull Saturday afternoon , so what else to do ? Yeah , just got to Frankenstein it back together with some hot glue .
Actually , I only had some 4 spare cams .. I could have just tossed the corrupting cam in the rubbish bin and swapped in one of the parked cams . But that would simply have meant I was still bored !

$9 23 knife at the rope (12 min 4 sec)

Some times , rarely - But some times . You have a win !

This knife has been teasing me for about a year now . And for my birthday I got some winning lottery tickets ( Chump Change ) .
Yeah , the wins were chump change as far as lottery wins go but ... enough money to buy a $9.23 knife that's been calling out to me for around 12 months or so . I mean , who am I not to fall for that siren song

A) For $9.23 it's really well made , no play - everything is tight - I mean nothing to complain about .
B) The factory edge was paper slicing sharp - That was a surprise - especially at the price point of 9 bananas .
C) The grind was ok except that each side was at a different angle - A lot of companies are doing that !
D) I mean , this is a no name budget junk knife right ?

Slicing rope :

Factory edge .......... Well that factory edge gave 80 slices which is almost double what I was expecting !

180 grit Diamond cut edge ....... This is where things got very interesting . Really interesting ! Especially if you like good cheap knives . Cheap and good dont usually go together ! when talking knives ( Until today )

Around 70 slices I noticed the edge was having issue getting through the edge of the paper , I suspected that the edge might be rolling . And the edge had in deed rolled . But the knife kept going and the roll started to diminish . The knife just kept going till the edge failed after 240 slices . 240 slices of rope out of a $9.23 knife . That is crazy .... This knife kicks a lot of more expensive knives to the curb . I cant even begin to rubbish Brand name knife makers enough when a cheap knife outperforms more expensive bragged about knives .

Yeah , buying a knife is like buying a lottery ticket ... Some times you win !

Got a nice 30 min thermal flight with my Heron today and my flying buddy got the same with his Night Radian. He offered me to have a flight and I launched with power off then slowly advanced the throttle but at 3/4 I heard severe vibration so landed. I looked between the spinner and firewall to see the firewall had a large crack that was allowing the prop and motor to flex and vibrate. With full power its highly likely the motor and prop would separate from the fuselage and result in an out of control crash. He will be using a new plastic motor mount. Reinforcing the front and rear plastic firewall with a stronger material is recommended. I will be using aluminum sheet.

Top hull and deck ready to go, then more rain!

Hopefully I'll get a window over the weekend to get the last of the color coat down.

Picked up some SprayMax 2k Glamour Coat.
Probably be a while before I get to that, needs to be a consistent 65* so it says.

Looks shorter and fatter than it really is.

It is convenient in this work to measure incidence, not relative to the chord line as is normal, but to a line parallel to the flow direction which results in zero lift. This line is known as the no-lift line, and eliminates the no-lift angle from our equations even for cambered aerofoil sections.

Been wanting something to carry around an Insta360 for a little while now. Saw this HappyModel Cine8 and figured for the price I'd give it a shot. Build is really straight forward and super easy since there's no soldering required. The included assembly instructions leave quite a bit to be desired, but it's simple enough to figure out how it all goes together.

The flight controller arrives configured for props out, so if you assemble it with the motors with the red dots on the connectors as motors two, and three then you won't have to change motor directions in BLHeli. The Whoop feels really solid once assembly is complete. The 1202.5 8000kv motors are also quite smooth and on the included 3s Tattu battery there is plenty of power on tap.

I've only had a chance to get a couple quick flights on it so far, but I'm pretty impressed with how well it flies. It doesn't feel quite as heavy in the air as I was expecting, and I'm confident that it will be able to get some great footage with the Insta360 on it. I'll update this after I've spent more time flying it....Continue Reading

As I am still waiting for several key parts to arrive through the covid curtailed postal system, something I did receive was a new old stock 1.3gHz Nexwave receiver module for my goggles.
I am not planning to be dependent on this alternative to a ground station in any way, but like the idea of having some freedom to fly my 1.3gHz planes and wings in shorter range situations without the hassle of setting up a ground station, which was my only previous option.
I found the early version of the Fatshark/Nexwave modules on AE at a virtual giveaway price, and after doing some research found there were three versions originally released from around six years ago with all of them enjoying a fairly short period of availability. This may have been due the the V1 and V2 versions having some serious image quality problems, and the V3 having sorted these problems out with a complete design overhaul where it then only spent a very short period on the market before getting pulled from sale... very strange as it's just a receiver.
The versions I found on AE were the V1 and V2-(1.6), and after carefully examining some old Youtube footage put up by dismayed users of these modules I deemed the image quality problem to be a termination issue which I was fairly confident I could overcome.

Upon receiving the module and testing it my suspicions were confirmed, the video output signal level was close to double the regular 1V p-p for composite, and only required level correction (matching) to get...Continue Reading

My lastest two scratchbuilts aren't doing so hot so went back to an old faithful wing that always flies though it has it's peculiarities.
I installed a couple of new elevon horns to equalize the throws, and replaced folding prop with regular prop. Flies quite nicely except for rolls which are slow and ugly due to the long elevons flexing at the ends. Will try to stiffen them up with some laminate and see if that helps.

Bought a useless not GOPRO camera but did find an old cell phone that fits on my baseball cap mount and isn't too heavy and it takes great videos. Happy about that.

Will fly this one around a bit, try to get my scratchbuilt plank working and order a cheap 12 dollar EPP wing kit that I can fly closer to home in a small space. Cheaper to buy this kit than ordering the foam and parts to build my own.

The motors still tend to pop out of their bearings & get stuck. Fortunately, they can still be forced back in, in the field. The encoders are now far enough inside to manage to stay in place. They still need shaft collars.

Anyways, the lion kingdom was left with a pile of solar cells after a failed attempt to make a car battery sustainer. Enough solar cells to do the job would end up costing more than a new battery. They make 1W in direct sunlight & 12mW in shade. Slightly more power could be extracted by matching the load to the cells. They were each rated for 60mA at 5V.

For a solar powered car battery sustainer to really work, it would have to be parked in direct sunlight all day. There isn't any electrified car port for thousandaires. It's hard to believe there was ever a time when houses were only 5x an average annual income, but lions still remember. It's been 20 years since the multiple became 10x & it's never gone down. The average electrified garage is now 15x the average salary. Lions believe the multiple will keep rising as long as the global workforce continues expanding faster than demand for labor.

There isn't any obvious, practical use for the solar cells. Besides the car battery charger, they would just power toys. At running speed, they would add 3/4 miles of range to a robot with a 4Ah battery. At walking speed, they would add 1.25 miles. Range extension would increase as speed decreased, until a robot could crawl as long as the sun was up.

Ironically, as green tech took off 10 years ago & then electric cars took off 5 years ago, interest in solar powered toys has gone away. BEAM robots, photopoppers, photovores used to be everywhere. Not sure if the solar hobby enthusiasm as been replaced with green tech day jobs or of the current generation sees solar projects as something government initiates rather than individuals in a garage.

This is a review of the JLB Cheetah, a recent budget rc car to be released. I got mine from Gearbest for about $270. This is the original monster truck version, and there is also a truggy version based off the same chasse and electronics, known as the 21101. Anyways, here is where I got mine from:

To start off, I will list all the items included in the box, and then talk about each of them. Here is what you get:

-An instruction manual

-A charger

-Rechargeable battery


-Car itself

To start off, there are a few different instruction manuals included. The first is for the transmitter, and it includes information on how to set failsafes manually on the receiver. It also has a bunch of basic information regarding how to set trims and dual rates, as well as reversing options on the radio.
Additionally, there is a lot of information on the esc, which has its own dedicated instructions. It talks about programming via a card, although I havent found what programming card is necessary.

Next, the actual users manual is very comprehensive. Although it is not in color, it has a lot of blown-up parts views, as well as information on setting hardware adjustments. Every part is listed and identified via a code, so you can easily find it online.

The charger consists of two pieces, the power cord and the power brick. Also, as I live in North America, I requested an adapter to utilize the charger,...Continue Reading
