The DJI / Ryze Tello (hereinafter, probably just called the Tello) is a small (127mm x 145mm x 30mm), surprisingly light (80g) flying camera that features optical flow and sonar stabilisation, a rechargeable 1S (one cell) 1,100mAh Li:Po (lithium polymer) flight battery, the ability to have it take to the skies directly just by throwing it, the ability to land directly in your hand and shoot a number of video styles.

The Tello is termed a "selfie drone" because that is one of its primary purposes; it is also designed to be flown indoors.

But the most amazing thing about this product is there is no remote control!!!

I love things that fly; that's why I took the bate and also why I added a seperate section titled "PRODUCTS DESIGNED TO FLY" on my website a number of years ago and created a new website just a few years ago specifically for flying machines of this nature!!! I was also attracted to some things that this drone has that many others don't...


The Tello is in the upper end of being a toy grade drone.
It's not puny for one thing (it isn't huge, but it isn't microscopic either); and although it has BRUSHED motors, I have it on good authority that some significant improvements have been occuring with brushed motor technology since the Tello was introduced in 2018 that I thought that it was worth the risk.

It sports a 720p camera with a 90° FOV (Field Of View); both still photos and aerial video can be taken with it!
I believe that the Tello can withstand winds of up to 17.67mph (28.44kph)!

As with any rechargeable product, charge the Tello first, and then you can pretend to fly a large dragonfly (well, that's what kitty cats would think it was if it were designed to be flown in a small living room -- you CAN fly it indoors (it was actually made for this purpose) but you'll want to be certain that the illumination level is relatively high.)


1: First off, load the app called, "Tello" (the Android version from Google Play) onto your 5G WiFi cellular telephone handset, and run it.

2: Connect the Tello's wiFi signal on your smartphone.

3: Press and release the POWER button on the drone (it's located on the right side of the drone's fuselage {this word is definitely *NOT* pronounced "fyoo SELL' uh jee" as Drake Parker from the TV program "Drake and Josh" would pronounce it ; the word is pronounced ""} near the front); the drone will begin flashing its front light to let you know that it is on.

3: Follow the prompts on your cellular telephone's display to set up your Tello (you only need to perform the setup routine once).

Press the graphic on the upper left that has an up-arrow on it, and then use your finger to "slide" the slider at the centr of the display to the right.

Congratulations, you're now a pilot!!!

For additional instructions & tips on how to fly, please read the instructional material that comes with the product.

On the Tello, press & release the "OFF/ON" button. This should neutralise it. -





The battery in the Tello is rechargeable.

To charge the Li:Po battery in the Tello, plug up the large end of the (not furnished) charge cable into any free USB receptacle on your Pee-Cee or Mac computer, and plug the smaller end into the female MicroUSB receptacle on the left side of the Tello's fuselage.
The LED on the front of the Tello should come on and start blinking. When this light turns steady, the charge cycle is complete and the cable may safely be unplugged.
Expect it to take ~65 minutes.

Fully charging the Tello's battery should give you approx. 11 to 13 minutes (advertised) of flying time.



This little drone is meant to be used as a flying camera in a large dry area outdoors or a large indoor venue (smaller rooms are kosher when slow speed is employed), not as a flashlight meant to be carried around all the time, thrashed, trashed, bashed, and abused; so I won't throw it against the wall, stomp on it, viciously chuck it at one of those wall-mounted porcelain uranators to see if it becomes broken (the Tello, not the whizzer!), try to drown it in the {vulgar slang term for a fudge bunny}bowl (loo) or the cistern, run over it, swing it against a loo ring (toliet seat), swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannoñata (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout, with handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoñata is only used to shoot piñatas to piñata parties away from picturesque Piñata Island), send it to the Daystrom Institute for additional analyses, launch it into the upper atmosphere of Gamalon V** so that chairman Sonji gets all piddled-off about it and kills the poor thing, or inflict upon it punishments that I might inflict upon a flashlight.

Besides, drones are meant to be loved, not punished.

There is an optical flow sensor on the bottom of the Tello; this helps to maintain the Tello's position at lower altitudes. The ambient light level must be fairly high in order for this optical flow positioning system to function though, so please do not expect it to function on night missions (well, "night missions" won't happen anyway; the Tello will refuse to lift off if the ambient light level is too low).

I believe the optical flow is functional to 3 meters (9.84 feet) in altitude.

The Tello is also equipped with a bottom-facing sonar to help it maintain precise altitude.

The Tello does not use a MicroSD memory chip as is usual for drones; it transmits images & video directly to your cellular telephone handset.

The Tello is suited for those with certain physical handicaps and those who have been chopped from the drone-flying arena because they have fallen prey to a stroke, like I have. This is because the Tello is flown WITHOUT a remote controller!!!
Ahhh, the next iteration of the "stroke drone" has finally been invented!!!


ALL OF THE FLIGHT VIDEOS ARE ON THEIR OWN WEB PAGE
SO THAT THIS EVAL. WOULD NOT BECOME TOO CUMBERSOME!!!






TEST NOTES:
Test unit was purchased on Ebay on 01-20-24024 and was received at 2:23pm PST on 01-24-2024.


** From the Star Trek: The Next Generation episode, "Final Mission".

While flying the Tello, I "hear" this phoney-bologna fake fictious song sung to the tune of, "Mello Yello" by Donovan, that goes like this:
To wit

♪ They call me mello Tello! ♪
♪ Quite rightly ♪
♪ They call me mello Tello! ♪

UPDATE 04-29-24
I purchased some spare propellers because sometimes they pop off during crashes and become lost. Now with spares on hand, that's one less thing to worry about.



UPDATE 04-30-24
The Tello is officially dead.
After accidentally installing an incorrect propeller, the entire motor came out while attemptng to remove it. Since I am physically unable to solder it back in place, the only thing I can do is throw it into the dustbin (garbage can).

However I wasted nol time in purchasing another.



UPDATE 05-08-24
The replacement Tello arrived yesterday, but my sister was furious and stated in no uncertain terms that all future deliveries will go straight into the dustbin (garbage can)

FWIW the new Tello appears to function better than my original.
The Tello that I got came with eight spare props, a prop removal tool, three flight batteries, a charging hub, and a USB-to-USB Micro cable to power the hub with. I believe that it's called the Combo Pack.



UPDATE 05-11-24
I flew without the prop guards yesterday, and this presents the possibility of the loss of all four props during a particularly violent crash. So here are the prop orientations for all props in the remote event of such a crash:

Left front: Clockwise
Right front: Counterclockwise
Right rear: Clockwise
Left rear: Counterclockwise



UPDATE 07-26-24
It would appear that the Tello may have blown a motor; but I won't know more until I attempt test flights later today.



UPDATE 07-27-24
I have verified that the starboard (right) rear motor has gone to pot; all I can do now is toss the Tello into the dustbin.:-(
Therefore, the dreadful,"Failed or was destroyed during/after testing" icon will have to be appended to its listings on this website.
