Super, itäs nice when the device is being worked as it was engineered. Could you please share the BOM please? I would like to repeat this one for home use, I guess the food idea to change the fan for some more silent, I guess Noctua should have something good.
Monitor Dell ST2320 23", 80 Eur (used) https://www.ebay.de/itm/184715290841, Microscope 16MP HDMI C-Mount with Stand (important) 167 Eur https://www.ebay.de/itm/393076808861, TV-wall-mount for Microscope 28 Eur https://www.ebay.de/itm/293622762004,  HDMI Splitter 1 in 2 out  8 Eur https://www.ebay.de/itm/283895490877, HDMI clutch 4 Eur https://www.ebay.de/itm/401771803238, USB 3 A/A Wire https://www.ebay.de/itm/253408856041, HDMI USB3 Game Capture Card 50 Euro, https://www.ebay.de/itm/402752184613  and if you want, the Larkbox 180 Euro.  I added a small laser pointer with a 3D-printed case onto the TV-wall-mount to better see where the focus is. It's easier to find an area on a larg board.

Сколько пикосекунд у тебя набежит за эти 40 мм?

Тут скорее будет играть взаимные наводки (т.е. по возможности сделай больший зазор и обеспечь корректность возвратных токов, например, полигоном земли под ними).

i can view it on a Display "and" on Laptop to capture images (or video) or using the LarkBox  with the Display for capturing images (or videos) without the need of the Laptop
