Looks like Stonhenge, while the stones are made to look like the Bootes constellation, because of the void. Who wants to open wormholes with me?
so what do we do with the larvae after if u dont have a chicken coop?
Thanks!
Anytime, glad it helped.

Genuinely curious, why does it take your calibration so long? Mine usually takes 5 mins or less- perhaps I am doing something wrong. Also, is RA Aggr supposed to be higher than DEC Aggr? I am wondering if this will help improve my guiding.
I'd have to go back to the video and check my step size. If the step size is small, it takes a long time to calibrate. I think the default is 2000. As far as the setting for RA and DEC, I set these for the best tracking and pay no attention to which one is larger. I just want the best resutls.
Amazing video thanks Fixed mine temporarily until i released mine had a split in it 👍👍
Yeah mine did too. I had to replace the extruder with the metal version
@@MyEngineeringProjects yeah same here just ordered a new one.
nice project
Thanks glad you liked it
Which way does the correct lens go? “) | 👀” or “| ( 👀”
I don't understand the symbols in the question, but it goes in the reverse order it was removed. I don't have this telescope anymore so I cannot check the lens.
What is corona
The Sun's corona is the outermost layer of its atmosphere.
Hillary clear video, thank you
Your welcome I’m glad it helped
Thanks for the quick tutorial! Does this also limit the charging when in sleep mode?
Yes it works all the time
Has anyone tried to make a mirror of a telescope on a photo of a polymer printer (SLA) using galvanization?
How do I get that needle?
The needles come with nozzle kits and are very inexpensive. There is a link for nozzles and needles in the description.
Would it possible to automate this? Make it into a go-to mount?
That would be a fun project. At this point you would need a board that contains Ascom drivers and then it could work with Astroberry or maybe with an AsiAir or something like that but it would be fairly difficult.
My printers nozzle isn’t clogged and my filament goes through fine when manually turn the extruder but when printing only a tiny string comes out
When you say manually turn the extruder, are you saying by hand or by the manual feed feature in the software? If by hand then you might have an issue with the extruder. If not, then the issue is somewhere else.
i want to set 77, but showing this " Error: Value must be either 80 or 100." how to solve it ?
I have not seen this one but I would set it to 80 and it’ll be very close to your target
It’s spinning and it’s hitting the element, but it’s just kind of making an annoying like scraping sort of mechanical sounding sound and no element is coming out. It’s also not moving the element into the extruder
That sounds like it's jammed at the spool. Can you manually unthread the spool? You might also try to take off the tube on the extruder and just see if it will pull it at least to that point.
@@MyEngineeringProjects I have to buy a new thing of filament because that’s pretty old filament. I have to make sure it’s not the filament thank you though.
Would this work when transferring the OS from a flash drive to to an NVME drive?
It should work, but I haven’t tried it
I know it’s an old video but did you leave the vinegar over night or did you rinse out after some shaking that day?
I let it soak with intermittent shaking for a few hours. All the work was done in one day.
Love this.presentation, easy to understand, short, fast and practical. Great work!
Awesome, thank you!
I'm new to 3d printing and this was driving me crazy. Thank you so much 🙏🙏🙏
You’re welcome 😊
Best CZcamsr you made a updated guide
Thanks for saying so. I'm glad it helped.
@@MyEngineeringProjects Thanks for the video, it's very helpful as a novice doing this stuff. Can I ask why you only have 3 bed clips on the print bed in this video instead of 4? Is this a glass bed? And is there an optimal position to place the clips with regard to the CR touch? Thanks :)
Yes it's a glass plate. The 4th clip caught on something and fell off. I need to replace it. 2 in the front and 2 in the back about how I have them works best for me.
Wish you had done this for a PC as well since the files are different.
I don't have a Windows machine to test. You could open a ticket up with ZWO. It's possible you have a defective focuser.
Really similar. Be sure you have the EAF plugged into your PC [use power supply if 12 volt] then download and unZip the EAF_FWUpdate_win_v3.3.8.. Then Run ElectricDeviceFWUpdate_3.3.8.exe. If it doesn't open then you have to install the Microsoft Visual C++ 2008 Redistributable Setup [run vcredist_x86]. Then open the Update screen and scan for the EAF, then Run. The update will proceed. Very similar to the above Mac version. It will verify the update, EAF Version 3.3.8 or similar.
Thanx for the Video. If I may ask, could one also add the Focuser to the Fine Tune/Gold Knob, by removing that one? Would that make the Focuser even smother/better? Many thanx.
Good question. The ZWO focuser is already geared down, so placing it on the fine focus knob is not necessary. They specifically designed it to go on the course knob. It would probably work o the fine, but I have not tested it.
Hows this comming?
It worked. I do need to gear it down because this free refractor has no fine speed control. You can see the first test here czcams.com/video/jrAV25ZPZSQ/video.html
I’m so sad bc this just happened to my Ender3 and nothing is unplugged. I am so new to 3D printers I don’t know what to do and I’m under a deadline to get things printed too 😭😭 if you can help me please reply! X
First check to see if your limit switches are connected. you might also need to check to see if they are plugged in correctly at the board. One loose switch connection can cause this issue
What attachment mechanism did you use to attach the lens to the mount?
I designed and 3D printed a support bracket
@@MyEngineeringProjects I thought it might be that. Unfortunately, we don't all have 3D printers.
How long will this battery last?
Not very long it’s just a demonstration battery. It has fairly low current.
@@MyEngineeringProjects will it work for a few minutes or hours? I want it to work during my school's science exhibition. Btw very nice video.👍
For a school science project, you can run the LED for a while a few hours probably it’ll be enough to show how it works
@@MyEngineeringProjects I have one more question for you. Can I use a thick aluminium wire instead of the galvanized nails?
It will work but bear in mind that each metal has different characteristics and produce different voltages.
I printed out the Hypatia Crayford on printables, and it works pretty well. It had a few issue I had to get around, making sure the heatsets are perfectly straight, and epoxying the knobs to the rod, as the grub screws slipped real easily, though my rod was stainless. Cutting the aluminum strips was also a bit of a pain, because you can't have it bend or curl, and it needs to be straight to fin into the depressions in the tube, a Dremel was too hard to keep straight, so a small hacksaw worked great for that. It is working fine for me now, though the collet slips out of the main screw cap, making it a requirement to forcefully pull the eyepiece out on occasion, but I think that is a printing issue, as I had one iteration of the cap and collet that worked fine, til I dropped it down a mountain.
I'll have to checkout that design. Glad you got it working well.
@NoGoBu more than this, if you look for videos like the earth this is totally away to bee the same...
Frequency analysis can be used to find the periodic error of your worm drive
Ok.
mine is still in chinese? help lol
Not sure what version you are using, but for V2 Try navigating to Prepare which is the top right, then going down to the A symbol which is just below the temperature symbol, then you should be able to find English. For other versions this would be different.
Great video and thanks! The other night I was going through the guiding process when I got an error stating "backlash clearing failed: Star did not move enough". Guiding would not complete successfully - any idea what might have caused this issue?
Try to increase the step size. During the calibration process, the ASIAir will command the scope to move a bit over and over. If it does not move enough to detect a change of position, the calibration process may fail. From memory I think mine is set to 2000 but I would have to confirm.
@@MyEngineeringProjects - Thank you - I'll give it a try!
@@MyEngineeringProjects - Just checked my step setting and it also says 2000. I did recently insert a different camera, so I'll try resetting as you mentioned in your video.
Yes very good idea. I had the same issue where I forgot to re-calibrate when I swapped cameras. Guiding failed until I deleted the calibration and started over.
When I put in my Sd card it never loads and stays on a blue screen
This is likely a firmware issue. You might have the wrong version installed for your board. Double check your board and the version you downloaded from Creality's site.
Thank you! I just went to clone an SDCard, and I discovered that rpi-clone has disappeared!
Glad I could help!
I have a Ender 3v1 with Cr touch installed. Do I need to reinstall the CR touch if I upgrade to Sprite extruder?
I’m not sure since I have not used the sprite extruder but you probably will have to move the cr touch to the sprite.
Mine extrudes whenever it is changing filament but during prints it just doesn’t extrude. The gold thingy moves but the silver thingy doesn’t
On my printer when I updated the firmware I don’t have the control menu I don’t know what to do
I would try a different version of the firmware. Their website that has the downloads is really hard to navigate. Also, check the board version number and make sure it matches the firmware you downloaded.
@@MyEngineeringProjects How would I do that? I don't see any old firmware on the creality website. My firmware for the board number is correct.
You don’t need to cover it up
I agree, but I don't like looking at it so that's why I put a lid on the box.
How easily could this be adapted for a larger mirror, like 203mm/8"
It would be challenging to do this. If you simply tried to scale the STL, then it would make everything bigger such as the nut holders and holes for the rods. This would break the design. One option is to import the model into CAD and then keep connectors the same but increase the size of the mirror holder and related parts.
@@MyEngineeringProjects I was also thinking it would make parts too large for most 3d printers. Would maybe have to divide them into the smaller pieces.
Hey Thank you for making this video Is that visualization window part of the stellarium app installed on your pc?
Glad it helped. Yes it is and it's also available on their mobile app. It's great for planning.
Thanks for this, and the USB copy/move method used to work flawlessly for me. But today, I tried to copy to a USB but the ASI Air Plus doesn't even recognize the USB stick. Any ideas? Thanks!
It the ASIAir won't recognize it, then likey it is corrupted or an incorrect format. I have had some usb drives fail without warning and cannot be mounted. Not sure if this your issue, but it's a good place to start. Try testing the stick in a computer first.
@@MyEngineeringProjects Thanks for your reply!
You dodged a bullet there! Quick and easy fix. BTW, most limit switches are inexpensive and cheaply made. It's not uncommon for limit switches to fail. I toasted a huge NEMA 34 12NM stepper because of a limit switch issue and I didn't catch it fast enough. From now on I only use configurations with normally closed (NC) limit switches. Creality is using normally open (NO) switches.
Interesting. I like the idea of the normally closed switches. I was lucky for sure. I heard a banging noise and knew I only had a few seconds to shut off the power. Fortunately the board and motor is ok but what a close call.
I have an ender 3 pro and my silver wheel is above the filament and i don't know how to get is to be in the right level as the filament , I have tried tightening the screw and it is still above the filament, any advice?
I don't have the pro version, but look for a spacer that should not be there like a washer of some sort. It also might be in upside down. Not really sure without looking at it myself.
My printer starts off fine then starts under extruding making the final product but with holes and less stability. Any advice ??
I would check to make sure you have the right nozzle size and that it is not obstructed. If it's too small or partially blocked, that could cause under extrusion.
Perfect job!
Thank you.
thanks man!
Happy to help!
Just started a dog poop compost about two weeks ago. Saw that today, when I opened the lid, there were a whole lot of maggots and freaked out 😮
Nice job on this video. I have a spare stepper motor/driver/controller if you want it.
Cool, thanks. I was tearing my hair out on this one. Glad I finally figured out what was wrong. I'm printing the next component now for the auto focuser.
