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.
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.
Built a retinal projector last night just for fun (and because i was curious what kind of image quality could be achieved).
WARNING : DONT DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING. SHINING LIGHT INTO YOUR EYES CAN BE SERIOUSLY DANGEROUS. DO YOUR RESEARCH BEFORE TRYING ANYTHING LIKE THIS.
Works Well, Produces a crystal clear image straight into your eyeball. unfortunately it seems that the alignment of everything and positioning of the eye needs to be to accurate for any practical use. The plan was to come up with a setup allowing us to make some kind of FPV goggles with this however without a lot of work this will not be stable enough on your head to remain reliable. the focal point must pass through your iris so a few mm of movement will cause you to loose the picture.
How It Works:
Image is produced by the Pico Projector. it passes through a variable ND Filter made of 2 linear polarising lenses, passes through the glass, reflects off the concave internal side of the magnifier (for refocusing) before finally reflecting off the glass slide and into the users eye (placed above).
Recently iv been working on a 2nd revision of the chassis used for my hexapod. So far I have redesigned the legs and have a clear idea of how the new body will look.
The new design focuses on increasing the range of motion, functionality and reliability. I have also been trying to get rid of the ‘prototype’ look of the old design in favour of a sleeker and more stylised appearance.
These parts have been laser cut and are now awaiting a sunny day to get painted. I have also painted a spare leg in the planned colour scheme as a tester. This is slightly messy due to the fact that it was painted whilst assembled, the new legs will be painted before assembly so this should not be an issue.
The long-term plan is to eventually release all of the designs for this hardware as open-source. This will probably happen once I have finished the hexapod and am happy with all parts of the design. Hopefully that will not be to far away but development is slow at the moment with many coursework deadlines approaching.
I have just been trained to use the UWE Laser Cutter. first test peice was a Frabjous Sculpture (http://www.thingiverse.com/thing:12271). Turned out ok.
I have so many ideas for things to make and up until now I have not had the resources to make most of them happen. I’m hoping access to this equipment will change that and allow me to rapidly prototype ideas and concepts.
IM GOING TO MAKE SO MANY THINGS !!!
Recently I managed to get hold of some spares from a few Hubsan x4 micro quads. I have been playing with these quads for a few weeks now and have many questions about how the set-up affects the flight characteristics.
Would angling the blades inwards make the quad more stable at the cost of efficiency?
Would a smaller frame make the quad more agile or would the props cause interference with each other?
Would angling all the props slightly forward make the quad handle more like a plane?
Could the quad support a V-tail set-up?
The final result fly’s nice and weighs the same as the original frame. Adding to this could cause weight issues but I still have a few grams of lifting capacity to play around with. This frame is also slightly smaller, each blade almost touches the one next to it. this seams to have made no difference to performance but the quad seams to corner much nicer due to the lower centre of gravety.
Over the past few days I have been having great fun flying my new Hubsan X4 Quadcopter. This is an amazing gyro stabilised RC quadcopter that is small enough to land in the palm of your hand. It can fly perfectly indoor or out and has enough lift to carry a key chain camera. Only problem is after reading on the forums I realised that the small blades are fragile and can easily become damaged during crashes. Many Quadcopters such as the Parrot AR drone have prop-guards to protect the props from impacts and so I decided to design a set for the Hubsan X4.
These parts were printed on my printrbot and the design files can be found on Thingiverse (http://www.thingiverse.com/thing:61127). The bumper weighs about 4 grams in total and is completely push fit. flight time is slightly reduced as you would expect but this is easily outweighed by the fact that bumps with walls and objects no longer stop the props (causing the quad to fall from the sky).
In the future I may re-design this to be a bit stronger / lighter if I get the time but till then I thought some one might find this useful.
