Taranis TX Respray.

Stock Taranis – This is how it started.

After removing screws on the back your presented with this mess of wires. I marked and removed all the switches before unscrewing all of the pcb’s.

I ordered a replacement shell and got a friend to spray it. This picture is much more representative of how the colour looks in person. Speaker, buttons and other hardware were moved over from my old front shell.

Parts were all placed back in the new shell, making sure switch and trim orientations were correct before closing the case again.

New screen glass is finally fitted and switch-nuts tightened. I have ordered replacement anodised switch-nuts but there on the slow boat so may take a while to arrive.

Looks like its stock with factory stickers and new glass (still with protective screen plastic). In these pictures it looks very blue, in person it is far more purple with a metallic shine and mat lacquer overcoat.

Very happy with the end result and it was well worth it.

QBOTICS PDB Tweaker Build

unyvpwk

Finaly got the parts together to put my Qbotics PDB into a quad.

ESC’s solder directly to PDB so that no high gauge cable is needed in the quad.

Motors and XT60 can then be soldered on and placed on frame. This is all of the high current wiring done in a tidy and reliable and easily serviceable way.

And a quick picture of the finished build. Only good picture i had before i made it dirty, it was designed for crashing after all.

QBOTICS Mini PDB V1.0

Its been a long time since i have done some hardware electronics but its something i want to do more of so i decided a Power Distribution Board for the quad was the perfect starter project.

The idea behind this is to develop a Mini PDB specifically designed for the mini 20A ECS that are about right now for 250 or smaller mini quads.

Also my first time using Kicad which was great once i worked it out.PDBinKicad
I have never had a PCB manufactured by a board house before but here’s what the OSH Park previews looked like.

During the wait i decided to CAD it up and see what the result should look like with LittleBee 20a esc’s in place (Having models of these parts will help later when i decide i want to make my own frame).180 core no naze

Finally today the wait was over. came home to find a nicely wrapped envelope form OSH Park in which i found my PDB’s.

MiniPDB

They look great. Super impressed with OSH park and i will be using them again. They are double sided, with solder resist and silk screen on both sides. Just 10 working days from design to my doorstep.

And the cost of all this excellent service? . . . . i got 3 copies for £8.40 including shipping. Couldn’t ask for more.

Just a quick post to say that i have uploaded one of my parts from my newest ZMR build to Thingiverse, check it out:

250 Slim Build now with FPV

DSC02972

a few weeks ago i got some FPV fitted to the slim build.

Its been flying great and has quickly become my favorite build. running a tiny camera and a tiny 200mW vTx.

Next to my radio for scale.

Need to move antennas in to switch to 6″ props but it flies good. Got some good camera angle and nice wide Field of View (110 degrees)

After crashing their plane a friend asked if i wanted to use up their batteries. Sure what could go wrong.

I was surprised to find this little quad using 1706 hobbyking motors and 12A ESC was able to carry a 3000Mah 4S quite happily. But it did carry a lot of momentum. A Tree caught me out before i could get a full flight time using this setup.

Switched to 6030 gemfans

Hope they don’t explode when i get some 4S batteries

Testing PID’s on Betaflight

Just switched to Boris B’s Betaflight.
It Feels AWESOME
Just trying to get it super smooth so i can get some video.

250 Slim Quadcopter

1 - Finished and Air-worthy

The goal is to build a super thin 250 size quad that will be used as a test platform for trying new parts and different firmwares / features.

To try and cut the size down and keep things tidy i made my own double afro 12a esc’s.
3 - DIY dual afro 12a esc

Esc’s flashed to BL heli and i would recommend this to anyone using afro esc. The tool is cheap, its super easy and it makes so much difference. running oneshot125 with damped-light. Ability to reverse motor output makes wiring much tidier.
4 - BL HELI

yep. it fits the trusty ZMR 250 frame.
5 - Testing Fit

FC and top plate in place
6 - FC and top plate in place

Just had to add radio gear and motors after this and was ready to fly.
1 - Finished and Air-worthy

its verry light, at least till i find some suitable FPV for it. Currently at 260 Grams plus battery, frame is only 14mm high and uses 8mm spacers.

This was built as a prototype using some old parts. its not high spec and i realise i could remove a lot of weight by removing bullet connectors but it’s a testbed. made for trying things, tinkering and swapping parts in and out.

It’s surprisingly quiet and i heard that these motors can have a good amount of thrust with a 6″ prop (when some arrive).

Planned Final Configuration:
Plan is to use a micro fpv cam and mount it on the space at the front of the mobius next to the main lens.
2 - Planned Final Configuration

Quadcopter Hyperlapse V2

Hyperlapse style video of a Quadcopter flight recorded with only a mobius action-cam.

The video is 6x faster than the original footage and has been De-fisheyed. To keep the video smooth it was run through through “deshaker” plugin for virtual dub before speeding it up. The output was rendered at 1080P 60FPS resulting in a 33GB uncompressed file with 360MB/s data rate.

The artifacts and borders at points in the video are a result of the warping that occurs during smoothing of the original video. some of the borders are then filled with image data from past and future frames by deshaker.

Due to the increased speed the original audio could not be used so was removed. I replaced this with YouTube music but its not great so feel free to mute.
