Wow, truly tricksy!

How did I not see this already?Wouldn't it work if you used a soda can with the ends cut off?

At the top-left of the topics list are options to sort by date the topic was posted, by the date of the last comment, or a mix of both.

Now, there's a challenge...

Here you go!

Interesting concept - were they created with a particular use in mind?

Might be worth moving this to Feedback.

I had a simple push cylinder mower.One day the cylinder stopped spinning. To fix it, I had to break it - there were no bolts or screws to open the mower. When I got to the part that was broken (a simple ratchet clutch), the actual part that took the whole load of cutting the grass was a scrap of injection-moulded plastic that engaged with a metal part and had worn away. I couldn't replace it because it had been moulded around another piece of metal.An entire mower killed by an unreplaceable part worth about 20p.

Reasons for not supporting their own work are many and various, but will probably include a change of email address or the author choosing not to be alerted about activity on their work.I do my best to respond to every single comment, and I am helped in this because I have set my alerts to ping me a summary once per day. Maybe this could be the default?The subject of "liking" comments has been raised several times over the years, and the general consensus has always been "this is not Facebook or YouTube", but maybe it's time to resurrect the Patch option, where you could send a digital thank you to an author, along with a pretty little picture to display on their profile? Here is an ancient forum topic to provide a little context:https://www.instructables.com/commun...

If somebody is going to spend several hundred thousand dollars to build a military vehicle in just a couple of weeks, I think they'll need a bit more motivation than you posting it on your page...

I agree with the sanding. Go back through my projects - not one has a smooth gloss finish...

Cool.

You're very welcome.

Good job I didn't counterfeit it then.I have not profited from this, my version is a different size, slightly different proportions, made from a different material, using a totally different technique.Mr Van Hoendonck has lost nothing, and actually gained traffic to his works, since I was careful to include a link to his website.

That's the useful stuff!The issue may have been fixed, though - I was just able to favourite that instructable, using Chrome.

I don't see any images?The development team would also find a link to the problem instructables to be useful.

Does the ball survive drying out?

Thank you!

You're welcome!I just wanted something a little different for Instructable #250.

Thank you!It would have to be a sink with straight vanes, though, so I could get between them with a drill...

You could try a trebuchet...

I hear you, brother!

Oh... That's amazing!

They are satisfying to handle... I really meant it when I said I don't want to give them away!

Thank you!I wish I did have a laser that powerful, but that's one of the great things about the internet - you can always find somebody, somewhere, with to tools and skills to do what you need.

Personal always trumps expensive!

That's going to have to be your decision - it seems getting things delivered is a dice-roll in some countries.Why not enter the contests, but if you "only" win a shirt you just don't fill in the delivery details.

In my experience of adhesive screen protectors, they don't have any affect at all.

Does it have to be 3d printed (could it be laser cut?)?If you don't have access to a 3d printer, could you enter a design file & appropriate mock-up images?

No - that will have been your own country's import duties and taxes.Instructables pays everything in the US, but they can't control what home nations do. For instance, I recently bought some parts from the US - when the package came through the airport, UK customs held it up and charged VAT on the value of the contents. I do often "get away" with it (when I won a high-end PC, UK customs charged me nothing!).It says somewhere in the T&C that contestants are responsible for any taxes and duties charged by their home nation.

Something to organise all his cables & chargers?A technology-free activity (take him for a walk or a meal somewhere romantic).Go retro - what was his favourite cartoon as a kid? Get a lunchbox with that theme.

No, it's just places where you might find other makers to enter the contest with.

If you check the site, they have hubs all over the world - there may be one near you!

My first thought for volume control would be a pill of QTC on the mouthpiece - the harder you bite it, the lower the resistance, the higher the volume (maybe sandwich the pill between two plates so that it's easier to bite & squeeze).Here's a description of QTC:www.iom3.org/fileproxy/348239Some suppliers will send you pill-sized pieces as free samples, but it's quite cheap anyway.

If you are looking for a group to join / compete with, have you tried Open Hub?http://movement.open.co/hubs

Oh, TT, we really, really need to see this in action!Please, post a video of it in action. Also, did it produce any useful thrust? Is it worth bolting one onto a go-kart (asking for a friend...)?

I'll have to add my voice to the call for files...

This one lights an LED when you get an email...https://www.instructables.com/id/Arduino-Email-Ale......maybe it can be tweaked to filter the emails by sender before sending an alert?

Cool.Derby Maker Faire opens it's call for makers soon - I plan to attend.

You're welcome!

You could try adapting the BEAM "Magbot" concept?https://www.instructables.com/id/The-Magbot-pendul...

Very nice, but have you actually started a fire with it?

IMO, the affiliated links do break the NC part of the license.Send them an email, include a link to the license, and ask them to either take down the commercial links or send you all the proceeds of the link.

Just don't hit publish until your team is ready to go and the contest has started.

Get your family involved - All the Kites are already members here, so we joined up and made a team.Or get your classmates and/or a teacher involved* and you will have a [temporary?] home for the bigger prizes you could win.Or do like mtairymd is doing (see his comment on this topic), and look for other instructablers in your area.Whatever, there is usually a way to enter most big challenges...*Like this: https://www.instructables.com/community/Instructab...

You're in an ideal position to enter this:https://www.instructables.com/community/Makerspace...Good luck in the contest - I'm a finalist as well.

Just hit the "unsubscribe" button. Simples.

Nothing you can do at the electrolysis stage can affect the burning stage.

They are allowed to use them, just not carry them.

Hehe!

You might find it easier looking closer to home - most people reading this have never heard of DT or A-levels.> Talk to your local hospital - is there a patient that that needs some special device to cope with their unique needs?> Talk to local businesses, large & small, ask if they need a new product prototyping. Or do they have a task that they are currently doing with a bodge-job of duct tape and string, but really need a proper thing?(When you start your actual project, don't forget to take lots of photos of your work and turn it into an Instructable as well as writing your official notes - being able to send people a link to your work in public view works great as a portfolio. If you need other help, PM me. I'm in the UK, occasionally teach RM to GCSE, and my son is star...

I don't suppose anybody recorded your talk and uploaded it to YouTube...?

If you go with DU35mm's suggestion, you could run the generator on sustainable biofuels.Heck, go the whole hog and convert a quad bike to run on old vegetable oil.

If you're looking at driving your chair directly off solar power, I am afraid you will probably be disappointed - going off-road will require full-power from your chair, which Google says is anywhere between 400-800W.In full, direct sunlight, using good-quality solar cells, that would require 2-4 square metres of solar cell, even more as soon as your chair turns the cells away.But, don't be discouraged - you can always look at increasing the number of batteries you carry, and maybe having a solar charger running back in the car or at base-camp.

You ought to write these up as proper instructables, they'd be very popular!

Haha, thank you!

Apparently nobody has ever made a live, featured project private before. I broke something...

I look forward to it!

Thanks for your kind words - don't forget to share an image if you make one!

Thanks.Somebody who knows more than me says that there is a "no index" instruction added to the instructable?

1. The "let's make" box at the top of the page is the search function.2. You can browse the site by hitting the explore button, then narrowing down by Category & Channel - for instance, these projects may be useful:https://www.instructables.com/tag/type-id/category...

Keep an eye on this forum topic:https://www.instructables.com/community/Positions-...It is updated whenever a new vacancy comes up, and some of them can be filled from other countries.

Unfortunately, because of reasons, the Pixlr functions no longer work when embedded in this site.The Pixlr website still works - I just edit my images there, save them to my device and then upload them to Instructables.https://pixlr.com/

Genesis of the Daleks!So, I have now watched way too many Dalek clips on YouTube, but I think you're going to be OK with what you have.If you watch this clip, the "leaves" that stick out of the barrel barely move (I'm sure there's one firing when they don't), and I can't see the central spike you have in your sketch (I'm pretty sure that feature is from a much earlier design of the Dalek).So, that probably means the BBC SFX boffins had the same issue that you are experiencing, and your minimal movement is actually accurate.All you need to do now is work out how to add the post-production beam effect in real life...

But, wait, there's more...You might be able to achieve the scale of movement with magnets, instead of levers.The red blocks are an electromagnetic coil wrapped around the inside of your barrel. You demote your big lever to a simple switch. Pull it, close the circuit, and the magnet attracts the (blue) lump of iron, which pushes the "leaves" out of the barrel. Let go, and the (green) elastic or spring pulls them back in.If you want to use bought parts, look for a linear actuator, which fits your specifications, maybe one of these: http://cpc.farnell.com/search?st=LINEAR%20SOLENOID...

Wow, flashback comment!No, I never did take this any further - at the time, I lacked the skill / resources / money to build a real ROV, and I guess I just sort of forgot about it.Please, feel free to use the idea in your own projects!

If they're inside the Dalek, it doesn't have to be pretty - a simple rod sticking out the back of the gun, pushed & pulled by the driver.

Will the toggle be operated by a person inside the Dalek, or outside?

Cool!
