Hey guys,
Progress report 2024-W38:

1. Developing and prototyping of HUD control panel is still on going. Results are satisfactory. Minor design modifications required.
2. Selected rotary switches have not sufficient rotational torque in conjunction with d30mm knob. The article to be replaced with a switch with higher rotational torque. A possible replacement found and ordered.

Hey guys,

Progress report 2024-W39:

1. Revised HUD control panel is ready to suit larger rotary switches. Mounting hole patterns were optimized.

These parts are 3d printed for prototyping purposes. The final article will have laser cut/engraved parts made of 3mm thk Perspex with thin (0.8mm thk) PCB sandwiched between them for providing a backlight circuitry.

Hey guys,

Progress report 2024-W40:

1. Backlight PCB for HUD control panel is finished. Ready to be ordered.
2. I have started to fit my custom PCB in existing Power supply enclosure for the HUD. It took me 6x tries until it fit perfectly, and all mounting holes are aligned. The main issue was that the enclosure itself has very uniform shapes and cannot be measure reliably by hand to create an accurate 3d model.

Hello everyone,

Progress report 2024-W41:

1. I've decided to use as many electronic components from original HUD electronics as possible. There are a lot of top notch capacitors, op-amps, transistors, etc. which can be easy implemented in my circuit design plus it will cut an overall BOM cost down as I have paid for that HUD unit already anyway. So basically I've spent all last weekend de-soldering parts and adding them to my pcb libraries for future use.

I've attached original SMPS board photos for reference.

Hi guys,

No major progress was made during 42nd week I've got my wife's Birthday on Friday and Dream Theater's show on Sunday haha \m/

Hi guys,
Progress report 2024-W42-48:
Slowly getting HUD ready got the pit. Last weekend got a successful test of LCD+backlight+optics+combine for the fist time.
Very nice visibility of the projected symbology even in direct sunlight.
Still working on pcb's for the unit.

PS. Sorry for blurry photos, my phone refused to capture it clearly...

Bump, @Phil Smith! Waiting for updates...

Hey guys! Long time no see haha
Finally real progress has been made building the HUD. Both hardware and software-wise. For later I cant thank @JDat enough for his valiant effort for creating an external HUD script to run it on raspberry pi. It's not just a copy of the Orbiter generated HUD on an external screen. Our plan is to feed the data from Orbiter via Orb:Connect over the ethernet and draw all symbiology from the scratch on the Pi directly, reducing the lag and increasing the frame rate considerably.. I let him to explain all details
From my side, I've finished all internal wiring and it's all ready to go. What's left are couple side covers, changing cracked and chipped main combiner glass and re-do front control panel - first iteration is fine, but no cigar - lettering is too deep and not that crisp + hot spots from individual leds are visible ,but it gets the job done for a time being.
Some pics are attached.
A short video of yesterday's test is below:

PS. the mid brightness knob on the front panel shown of the photos is fitted temporary and already replaced with proper sized one.

Hi guys!
Fresh quick updated straight from the JDAT's lab, looks like data connection between Orbiter and the external "symbol generator" is working! All data transfered over ethernet using Orb:Connect.
Not all functions are implemented yet of course, but it is a huge milestone:

Again, massive thanks to @JDat !!

Little update on the external HUD:
@JDat and I (mostly @JDat!) keep polishing the surface HUD.
Some symbols added (velocity, vertical velocity, altitude, AoA, G-force, Mach number, gear down indicator), but they are static (hardcoded) for now.
Pitch, bank and azimuth angles are working now, getting live data from the Orbiter.
Velocity vector is a stubborn one! Still doesn't work as intended.. Its scale is off big time comparing to Orbiter's on screen HUD.

Sharing some backstage footage without @Phil Smith permission. Who said that VNCMFD addon is useless? Button cougar software and remote multiMFD in development...
