I've slowly been making improvements over the past few weeks! Code The code is becoming more refined with every new problem I find (including when my local NWS radar station was down for 5 days for repairs). The navigation switch is more response,...
alpha 11.0 New design Sketches for custom PCBs: PCB prototyping, 3D printing, new designs. I hit power path and size limitations with my breadboard prototype spider for while...and then i was offered sponsoring by PCBway. love when things come together...
After 2 full days of hacking, the lion kingdom's recycled trackpad successfully communicated with the X server, thus becoming the world's 1st Elan 33059 to communicate with an X server with a PIC2450 as a bridge. The USB driver was originally ported...
If you look at our camera setup closely you will notice that the cameras are mounted the wrong way around. When you work sitting at the "open end" of the stand, things nearer to you will end up at the top of the screen - not what you would expect. But...
Development Overview The handheld controller is one of the critical parts of the Valor sUAS ecosystem. It allows operators on the ground to take control of the UAV without the need for a bulky ground station. The role of the handheld controller is critical...
The underwater wings are to convert the vertical motion (wave) of the hull to small forward propulsion. So the boat can sail forward without the need for energy. I was planned to build the wing core from wood pieces. Cut the shape, then sand it down...
The gatorade bottle & level sensor worked well, after the initial problems with corrosion & siphoning. Sadly, 1 month submerged turned the motor into a rusted mess. The motor bearings & set screws rusted. All the steel farsteners rusted....
My initial plan for the enclosure was just to order it 3D printed. Even home printed enclosures look nice enough, and commercial printers like HP Multijet Fusion give very nice looking results for affordable prices. The cost for the complete enclosure...
Working without prior knowledge gave me an opportunity for (almost) boundless experimentation while designing the case. It was a great playground to learn and see for myself what I could do with 3D printed parts, in order - among other things - to not...
I have made a few major design changes and decisions since my last update. First I broke the project up into stages so that I could better organize myself and focus on specific aspects of IRA's development. Sticking with the flower theme...
A drawback of the gimbal mechanism is its kinematic singularities points. These are points in its workspace where, when performing inverse kinematics to track a path, minimal changes on its pointing direction results in large motion of the joints. This...
So basically I'm terrible at designing housings for my electronic creations - things change mid project, the housing ends up being sub-optimal to outright disruptive - check out my FrankenFlight controller to see an example. So this time round I decided...
While working on the oscillator section I looked into ceramic filters a little more and found an alternate which I think will work better than the 2 kHz device we chose previously. The LTC455GW is also a 455 kHz filter but has a bandwidth...
Results after computing some SecSavr concerns: Spend the £17 extra to change 2x27mm cylindrical tubes into 1x40mm box tube that is 1m long I can get them cut to size, but unlike tubes, they are bought in fixed sizes. If I want a length more than...
The comments on this article here is a useful read for what could be done to make 3D printers easier to use. I'd like to imagine what could be done on the slicer side of things. The most notable points are the debug process of the printer itself...
