Elsie tends to be active in the evenings - her light is on a timer, and when it goes out she starts exploring. It's really hard to tell if they're asleep, since they don't close their eyes, but if I lift her out for a play, she's always up for a chance to escape...
Aesthetics - I didn't want the tabs showing through the walls.It's also a lot easier to build this way.To be honest, if you've glued the edges of the felt in firmly, you probably don't need to glue the slopes at all - they endure almost no load at all, and the felt is thick enough and tough enough to hold everything up.This actually went away to university with my eldest, and is still fully intact.
What device or software are you using?
Wow, sorry about that - I guess nobody else has made one of these, since you're the first person to notice!I've added two more files, both A2 sized, with all the parts you need.
That's why I said "assuming constant acceleration"!I've asked somebody with more rocketry knowledge than me to have a look - we'll see if he's able when time zones catch up.
See the "Let's Make" box at the top of the page?That's the search function...
Assuming constant acceleration and straight-line flight...v = u+atFinal velocity = initial velocity + (acceleration*time)Initial velocity = zero, so...v = at"a" = acceleration in m/s/s1g = 9.81m/s/sSo, v = (number of Gs) * 9.81 * (time of flight in seconds)See: https://en.wikipedia.org/wiki/Equations_of_motion#...
It better, or my students are in deep trouble... LOL
Thank you!It feels really nice after time in your pocket and hand.
Very nice job!
Same here.Unless it's an ad that premium members don't get?

I think you may have the wrong person - I have never built this project.Could you give me a link to the video you think is removed?
It would help if we knew what country you are in, what your budget is, and whether you are wanting to use it as a hobby/craft tool, or making cards to sell?
+1It can take a day or so for some servers to synchronise.
Video-only projects are in a small and shrinking minority, so it's not that big an issue, really.
You need an Energy Stick!They're available all over the web, but here's an example:https://www.stevespanglerscience.com/store/energy-...Connect one end to your metal plate, connect the other to the trainee's skin (say, an ankle strap), and as soon as they touch the metal plate with the needle, the Energy Stick will light up and make noises.
So you want to register and record a needle being placed on a plate? Are you trying to keep track of equipment during surgery?What about this?https://www.instructables.com/id/How-to-Connect-an...
How hard will the needle be touching the plate?Will it be attached to anything?Do you need the plate to send a signal to another device, or just show a visible sign of contact?
(I forgot to add an image.)
Since Pakistan is not on the list of embargoed countries, and you are over 13, then, yes.If you win anything, you will probably need to get your parents' permission to receive it, but that will only need a form filling by email.

Unfortunately it seems that the problem about units is so great, the author has already deleted his account.
Most members and authors are American, so still use Imperial units.There are many ways to write dimensions that are understandable to human readers, but it would (I think) be incredibly difficult to write code to trawl through >200,000 projects, identify Imperial units and insert conversions.If you're reading an instructable for pleasure, or with a view to following it (rather than actually following it), there's no real need to accurately translate units. If you're getting ready to follow a project, that same computer you're using to read the site also has access to google, which can easily convert most units to most other units.

Sounds cool - thanks for the comment!
My first instinct would be to lift off the top plate, put a "sausage" of Sugru around the top of the pedestal, and then quickly fit the plate back in place.Sugru is food safe, and acts as both a filler and an adhesive.https://sugru.com/about
Thank you.Be aware that the site has had many changes since I wrote this, and some of the steps are not valid any more.

Odd - that sounds like a bug. It might be worth dropping an email to firstname.lastname@example.org and asking them to check it out.
You have to click EDIT first, then the MORE button is to the left of the page.
I can't tell definitively if it is real from the photos, but I can say;> Tortoise/turtle shells do peel, even when they're alive. [LINK]> Going by the garbage around it, it's not huge, so (if real) probably young.> Looking at your third photo, it is potentially possible that it walked into the dumpster when aiming for the sea in the dark.> In some species of sea turtle, the neck & shell do sort of merge into each other (streamlining?)My instinct would be to pull it out of the trash and look properly - is it meaty? Are there wounds? Or obvious signs of manufacture? If it's only been there a few hours, it could even still be alive!
I've fixed it - for some reason it objected to the final "/"...
Cool, thank you.
You need to move this from "Bugs" to "Technology".
I've never heard of "crotch grain" - does it have another name, or is it a special thing for walnut?
Traditionally, musical jewellery boxes are clockwork - the ballerina is on a spring, and gets bent over by the closing lid. This jams the mechanism, and prevents it playing unless the lid is lifted.These mechanisms can be bought from several online sources - here is one I randomly googled;http://www.njdean.co.uk/musical-movements-mbm18bal...
Since you're discussing potentially sensitive information (your passwords), This might be better sorted out via email.Drop a line to email@example.com, and they'll be able to pass it on to the right member of staff to help you out.
You're welcome - don't forget to take plenty of photos and notes as you work, and you can write your own instructable.

Try starting your own forum topic, and make sure you do not include your phone number in such a public forum. Just let people add comments to your topic, or send you PMs.(In fact, I would delete your comment if I were you, just to make your phone number secure.)
Yes, you can put it in the promoted section of your page, but I wouldn't bother adding "updated" to the title.You should also consider using social media (Facebook, Instagram, Pinterest, Twitter and Tumblr) - just promote it as if it were new, or "Here's one from the archives that I've updated".
You're very welcome!
I can tell you from experience that the delays are usually beyond the site's controls - you can't really tell folk off for being slow when they're the ones paying the bills...
Agreed - folders would be nice.
I didn't do anything myself, but you're welcome.
I think that would be abused by the sorts of parents who do their kids' homework projects for them.Better to look for the occasional "first time author" contests, or maybe follow them up with a "second project" contest?
It will really depend on how many shirts you want, how many sizes, how many colours of shirt, how complex a design, how many colours in the printing etc.Of course, you could always try...https://www.instructables.com/howto/screen+printin...
I'm afraid you do seem to be caught in the arcane intricacies of the filters - if a human hasn't released you by the end of tomorrow, drop an email to firstname.lastname@example.org and ask them to sort it.
5mm MDF + 40W laser = expensive sootThe only 5mm material I cut is acrylic - any form of wood just chars along the cut.
Check your inbox;-)
I meant the search...
Worth a try.
Have you tried...?https://www.instructables.com/howto/bluetooth+ardu...
Have you not entered this in the Valentine's contest?
As long as you got the "received" email, you'll be fine - it's the weekend.
If this is continuing, drop an email to email@example.com, and the team there will look into it for you.
The only personal information viewable by non-admins is whatever you type into your profile. The only personal information saved on the site is your email address, and if you are worried about that, you can change it to an account you create purely for that purpose.
It's a 40W laser.I would cut 3mm MDF at 65% power and speed 15 If the OP means 3/4 inch MDF, my 40W would not be able to cut through at all.
Simple - just follow the instructable and build your own version. Feel free to follow the plans as closely or as loosely as you like.

Views & favourites have no official influence on the results, but I think it's fairly obvious that the more views you get, the more likely you are to get a vote, and the more favourites you get the more likely it is that those viewers actually voted, and maybe even shared your work.
It would help if you added pictures of the bike and cart, and said which way round you are trying to attach them.
Pro and premium are the same thing - there was a name-change that is taking a little time to settle in in places.If you want to pay for Premium, go here:https://www.instructables.com/account/goproI've added a screen-shot of the various benefits of turning Premium.You can turn premium without paying, though, by writing and publishing an Instructable that gets Featured by one of the Staff or Community Team. - part of the reward is a free Premium account.
Cool - post pictures when you're done!

Invest in a reasonably decent stills camera, and create step-by-step instructables, rather than just videos.Consider social media like Twitter & Facebook - create an opening image that teases the audience enough to open and share a link (I have noticed that images like these get shared a lot more than "ordinary" images).
You need to upload your photos to the site to use them.If you're following the "how to embed photos" instructable*, the site has been updated a number of times since that was written (4 1/2 years ago!), and I don't think that works any more.*https://www.instructables.com/id/How-to-Embed-Phot...
If I'm making a variation on a box I usually start by spending a few minutes on www.makercase.com, selecting finger joints in the options.
There are services online, hackspaces, makerspaces, and lots of schools own them now.

Awesome - thanks for sharing!
Without going into details, HQ have ways of spotting sock-puppet tricks like that.

Silly question, but how do you know the spam you get is thanks to your data being stored on this site? I've been a member for 11 years, always with the same email address, and I get no spam I can link to instructables (at most, I only get one or two pieces a day, actually, most of which is faked to look like it comes from FedEx [a service I don't use], Snapchat [an app I have never downloaded] or Amazon [who do not know my main email address])
Oh, yes!Thank you!

Here is an SVG file of the basic parts, with a screenshot of the ECP file so that you can see how many of which parts to duplicate.
ECP files are used by laser cutters.In my case, the laser cutter software is LaserCut 5.3
