Do you even orbit?

This 2 overviews above are wrong cause ‘they’ used orbit data –around the sun– to calculate how long a planet was in a gate or line, but the movement around the Rave Mandala wheel is an orbit –around Earth-.

So I did some calculations and came up with this:

Mercury as short as 358 days and as long as 405 days, on average 366 days.
Duration in one Gate: ~5.7 days
Duration in a Line: ~22.9 hours

Venus as short as 293 days and as long as 410 days, on average 369 days
Duration in one Gate: ~5.8 days
Duration in one Line: ~23.1 hours

Mars as short as 528 days and as long as 712 days, on average 679 days.
Duration in one Gate: ~11 days
Duration in one Line: ~42.4 hours

maybe 64Keys were right in their overview:

close and save

make

switch off mini (only)
put on pin over 2 prongs on pcb buddy board
switch on mini

sudo service klipper stop
make flash FLASH_DEVICE=0483:df11
sudo service klipper start

switch off mini (only)
take off pin over 2 prongs on pcb buddy board
switch on mini

restart firmware in mainsail

Original Prusa Mini+ Bear mod

today, I finished the main modification of the printer (I only want to change the wires soon) so the whole frame is changed, the hot-end, extruder, heatbreak and nozzle, and all printed parts were PETG are now ASA, instead of a Cantilever design it is now an H-frame with double Z axles, so the frame gives rigidity and structure to the printing, yet still running the original Prusa firmware (with some added G-codes)

Rocket Transits Rippling Sun

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2022 May 31

The featured image shows a Falon 9 rocket transiting in front of the Sun in mid May. The heat from the rocket's exhaust makes the Sun's outline appear to ripple. Please see the explanation for more detailed information.

Rocket Transits Rippling Sun
Image Credit & Copyright: Michael Cain
Explanation: The launch of a rocket at sunrise can result in unusual but intriguing images that feature both the rocket and the Sun. Such was the case last month when a SpaceX Falcon 9 rocket blasted off from NASA’s Kennedy Space Center carrying 53 more Starlink satellites into low Earth orbit. In the featured launch picture, the rocket’s exhaust plume glows beyond its projection onto the distant Sun, the rocket itself appears oddly jagged, and the Sun’s lower edge shows peculiar drip-like ripples. The physical cause of all of these effects is pockets of relatively hot or rarefied air deflecting sunlight less strongly than pockets relatively cool or compressed air: refraction. Unaware of the Earthly show, active sunspot region 3014 — on the upper left — slowly crosses the Sun.

Synology DS716+II

High-speed gegevensoverdracht en engine voor hardware-encryptie
Uitgerust met een quad-core processor en AES-NI hardware-encryptie, de DS716+II biedt razendsnelle bestandsoverdracht – ook voor versleutelde gegevens. Met Link Aggregation ingeschakeld, levert de DS716+II een gemiddelde lees- en schrijfsnelheid van respectievelijk 226.1 MB/s en 141.19 MB/s 1, terwijl de overdracht van versleutelde van bestanden aan een verbluffend vergelijkbaar niveau van prestaties wordt uitgevoerd, meer dan 226.09 MB/s lees- en 138.04 MB/s schrijfsnelheid. Dat betekent dat u uw gegevens kunt beveiligen zonder aan prestatie te moeten inboeten.

Dual LAN-poorten met storingsbeheer en ondersteuning voor Link Aggregation
Uitgerust met twee Ethernet-poorten met failover en ondersteuning voor Link Aggregation, de DS716+II zorgt voor een continue uptime van het netwerk, zelfs als er een storing op de LAN-verbinding van een poort voorvalt, waardoor de kans op storing en kostbare downtime worden vermeden. Link Aggregation verbetert de verbindingssnelheid die hoger is dan deze van een enkele netwerkkabel of poort.

Eenvoudige installatie en probleemloos onderhoud
Eenvoudige installatie en ondersteuning voor hot-swappable harde schijven zorgen voor een gemakkelijke onderhoud en continue werking als een harde schijf aan vervanging toe is. De DS716+II is uitgerust met een passieve koeling zodat deze niet afhankelijk is van een speciale koelventilator, wat cruciaal is bij een storing.

USB 3.0 en eSATA zorgen voor een snelle overdracht naar externe opslagmedia
De DS716+II beschikt over USB 3.0 en eSATA-poorten om verschillende soorten externe opslagapparaten te kunnen aansluiten, en tegelijkertijd snelle en efficiënte bestandsoverdrachtsnelheden te verzekeren. Ondersteuning voor USB 3.0 dat overdrachtsnelheden haalt tot 5 Gbps en 10 keer sneller is dan USB 2.0, wat betekent dat er heel wat minder tijd nodig is om gegevens over te dragen naar harde schijven en minder stroom wordt verbruikt.

4K Ultra HD video versleutelen
Voorzien van een hardware-versnelde transcodeer-engine, met de DS716+II kunt u H.264 4K / 1080p video’s transcoderen en streamen naar high-definition TV, digitale mediaspelers, mobiele apparaten en computers, zodat het afspelen van video’s gemakkelijk is zonder een speler van derden te installeren
