Yes, easily. You have two more stepper controllers, so you can use one for zoom. As for interface, it's a simple Arduino, and there are plenty input options for that./thanks
Thanks :)
View Instructable »I'm still working on that. But I'll probable use some shelf supports. In this build it was just quickly mounted on some large clamps, as you see in the prototype video.I submitted for a contest, so corners were cut for deadline :)

For time, it took me a summer :) But I'm a computer scientist and not a professional, and I only work on my projects when I find them interesting. You can do it much faster than that. Clearing the area and removing an old shed, took the longest. Then constructing the foundation, next laying the deck. Building the greenhouse was the fastest. And then some trimmings in the end.I'd hate to give you a price, because the price of the deck will vary with where you live, and you can cut the price in half, or double it by simply choosing another type of wood. But if you calculate your cost of wood, and add 15% for other materials, you'll be in the ballpark.The greenhouse only has the cost of the house itself, plus a little cement and sand.Sorry I couldn't give you a better answer,...
- KronBjorn commented on KronBjorn's instructable Garden Deck With Greenhouse
Thanks! It's not that complicated, but is was a lot of work, and I questioned the size of the deck several times during the build :)That does not sound like an unreasonable amount of time for a staircase, stairs are hard in my experience. But I did learn some time ago, never to add up cost or hours for my projects ;)
Thank you, I have added it to the BOM :)
Thank you for the nice comment :)Sounds like a great plan reusing the windows, I would love to see that!

- KronBjorn commented on KronBjorn's instructable Garden Deck With Greenhouse
Thank you :)It gives me great joy if I should succeed in inspiring people to build something, which I enjoy so much myself.
Of course. I didn't put it in the instuctable, because I did not want to endorse a specific greenhouse, and you should also be able to use any kind.It has a different name in different countries, but if you search for "Sirius 13000", you should be able to find it. If you have a choice of color, I would recommend the black profiles, as they look very nice with a green garden.Thank you for the nice comment :)

Thanks,
Yes, there is nothing like rockets, fire and explosions to get kids excited about science :)
Thanks for the comment, I couldn't wish for a better reaction to a build :)
View Instructable »Yes, a cheap single stage from eBay.It is also good for other experiments, like inflating marshmallows and boiling water at room temperature :)
- KronBjorn commented on KronBjorn's instructable SaturnV Vacuum Rocket Launcher
Yes wouldn't it be great to have equipment like that ! :)I only once caught a single blurry frame of an object going through the tape.
View Instructable »Thanks, that is a great idea.Maybe it would also illustrate how air/smoke is pushed into the acrylic tube ? -I'll see if I get time in the weekend.
- KronBjorn commented on KronBjorn's instructable SaturnV Vacuum Rocket Launcher
Thanks, glad you like it.
I have tried two types of packaging tape (brown and clear), and foil cut round from a big sheet. They all work, so my impression is that it is not that sensitive to type of film.Sometimes the rocket will break the tape, and sometimes the air pressure will lift the tape, before the rocket passes. You can only see this with a slow motion recording.I have experimented with two layers of film, and it sometimes work, but a single layer is most stable.Thank you for commenting,

Thank you for the clarification, I will consider that.Regards

Anyone ?The reason I'm confused, is that it says "homebrew drink-related projects" in the details, and this is one of the images of the contest:Thanks,
