I've found some information regarding glass coatings, really interesting: These glasses use another technique of a special multi-layer coating called rugate technology. Rugates act like a single inhomogeneous film with a refractive index that varies continuously and periodically throughout the...

Hey guys, Progress report 2024-W37: Major progress on HUD front control panel design, including controls layout. Interface adapter was design, printed and tested. Front panel backplane was 3d printed for testing and fitting proposes. Final article is planned to be laser cut 3mm acrylic...

Hey guys, Progress report 2024-W36: 3D modelling of combiner assemble is finished. HUD’s front control panel design is underway. Also I’ve manages to acquire 506m of triple core shielded PTFE cable from Ebay really cheap (weights a ton!). This cable will be used for connecting potentiometers...

Hey guys, Progress report 2024-W35: 1) Missing Combiner assembly is acquired from Ebay. Larger glass is broken but can serve as a template for ordering a substitute made an ordinary float glass. Currently the broken article can serve as a good test piece providing a benchmark performance...

Afternoon everybody, Progress report 2024-W34: 2 of 2 10” MFDs is assembled back and fully tested. Nothing more to report this week tbh :)

Hi all, Progress report 2024-W33: Custom Backlight assembly is finished. 1 of 2 10” MFDs is assembled back and fully tested.

Hi guys, Progress report 2024-W32: After playing with custom backlight for HUD LCD I’ve decided to upgrade backlight assembly of 4” fuel indicator and 10” MFDs as well. The main issued with those Chinese displays is a lack of nice an even backlight, causing the panel looks quite dim even at...

2) Yep, CANopen it is. SpaceCAN 👍 Nowadays I think SpaceWire is a way to go with new designs: https://en.wikipedia.org/wiki/SpaceWire No chance I can obtain a physical layer for this 1 lol 3) My first iteration of MFDs had USB interface for bezel buttons – with 1x or 2x mfd's connected - it...

Yep, definitely. Anyway, I think I have to take a break from the hardware design and get deep into coding side of things asap haha My main interface design requirements are as follows: 1) Orbiter - simpit communication - over ethernet. 2) Communications between different simpit sub-systems -...

I was thinking of passing all "raw" data displayed on the HUD from Orbiter such as heading, speed, acceleration, etc., etc. in form of variables and draw a custom HUD imagery directly on Pi (sort of a symbol generator)

Thanks Urwumpe, I'll try to go this route and see it is achievable or not. Alternatively, all necessary variables can be passes to HUD raspberry pi via ethernet and draw it locally utilizing Pi processing power.. Just thinking out loud

Hey guys, As I've been building my simpit and I'm wondering whether extracting HUD data and sending it over a local Network possible or not? The main thing is ability using raspberry pi + LCD as an external HUD There was an old topic dated back to 2012, showing it is possible to draw a HUD in...

Hi guys, Progress report 2024-W31: Parts for HUD projector are received from China. Initial prototype of custom LCD backlight system is finished and tested satisfactory. There are no visible “hot spots”. Painting is done. Inner part of the reflector is covered with aluminium foil (no shown on...

Hi guys, There was no major progress during 30th week - I was on my annual leave visiting Edinburgh (hail to all Scottish Orbinauts here! 😊 ) I'm still waiting for parts coming from China (led chip and heatsink, hopefully they will be here today-tomorrow). No sim related photos attached lol

Morning all, Progress report 2024-W29: Work on the Hud unit continues. I’ve decided to design all electronics myself instead of bringing existing circuits back to live. Main issues of reverse-engineering this beast are custom chips for which I cannot find any info, let alone pinouts or...

Hi guys, Progress report 2024-W28: MFD buttons and corresponding lids are finished. Circuit reverse engineering of the HUD unit has been started. Tracing of input EMI filter is complete. Low voltage power supply is underway. The only 2x things left to finish those MFDs hardware-wise are...

Hi guys, Progress report 2024-W27: Design of new MFD button cover lids is finished. All new part are printed and test fitted. Painting of MFD buttons and button cover lids are complete. Assembly of the fuel quantity indicator is finished.

Hi guys, Progress report 2024-W26: 88x MFD’s and fuel indicator’s buttons have been painted black and filled with white wax to provide visible markings. Some paint defects were corrected with black marker. Ready for a clear coat application. 3D model of the HUD unit is complete. Designing and...

Just very very crude test of mirror and collimating lens: Static image source – Phone’s LCD (at full brightness). Combiner – plain 2mm float glass for picture frames. Looks very cool already, but sooo far from the the final product.. haha
