Browse by followed categories and users

Hi all, I am following some categories (such as woodworking, home improvements, etc) and users. Is there is a way to browse only through the followed categories/users instead of the homepage featured instructables? Something like a personalised homepage? Sorry if it is already been asked, I searched in the forum but have not found an answer. Thanks in advance!

github!

I just learned that codebender is closing up shop. Sometimes my arduino folder feels like it's a mess so I was using codebender for my final code. I guess I should be using github though. I'd like some guidance about how to better use github. I'm familiar with other people's github pages but I'm not sure about how to use my own. Can the instructables community help me out? Thanks!!

does anyone know how to remove bubbles from the kitchen sink?

Do you know those pesky bubbles in your kitchen sink that always reside after you finish washing up the dishes? well i know them all too well and they never pop however much i poke them or blow on them or hair dryer them :( i had a look online and found a idea that you can tip ground pepper on the suds to pop them efficiently, but all it did was pop a couple of centermeters of the bubble monolith and now my sink smells like pepper :( does anyone have anyone ideas/experience as to how sove my bubbly problem?

Looking to activate a loud buzzer with a board speaker...

I have a home security system (fortress SO2) and the door chime only comes thru the little board speaker.  We have a loud shop and sometimes we are in the back and cannot hear when someone enters.  I would like to activate an external buzzer with the speaker chirps.  I've search the interweb :-) and haven't been able to find something that will for sure work. I'm no electronics guru but I can follow instructions or would pay if someone wanted to build me something that would basically activate a momentary switch every time the the little speaker chirps and I could wire up the buzzers from there.  edit: I can solder if needed

What are the restirctions/requirements to play with model rockets in your country?

I wanted to start again with an old hobby of mine and buy some rocket motors and one or two easy rocket models. Just for the fun of seeing things to fly high and come down slow you know? Depending on which country you can call your residency now you might luagh about what happened to me: I went to first model building shop I could find nearby in my Yellow pages. Of course that had no clue about rockets, not even remote controlled cars as they only build build models for multiplayer board games. Next shop was selected a bit better with a focus on all things remote controlled. Here I was told that only a few shops actually sell any rocket related stuff due to the tough legal requirements of storage, handling and selling - WTF?? (excuse the language!) But at least I got an address for a shop that would be abe to help me figuring it all out. Last but not least I finally entered a shop filled with all sorts of model rockets, from simple to realist replicas of Saturn 5 engines. "Can I see your permit please?" "Do you have a club memebrship card stating you can buy engines?" "Can you provide the required details on your storage facilities and fire control system?" That were just a few of the questions thrown at me when I went to the checkout with 3 little rockets asking on where to find the engines and ingintion kits..... Turns out here in AU it is far easier to obtain a firearm and license than to get what you need to shoot a plastic rocket 100 or 200m high in the air.... Without being a member of a recognised model rocket club you won't have access to a legal launch area. Without your club permit you can't obtain a license required to buy a model rocket engine - yes we are taking about these paper tubes every kid uses.... Without the license, club membership and the required club permits you will never (legally) buy a rocket motor... To make things worse the 4 clubs I contacted only supply motors they buy to their members, at about 20% above market price of course and you won't get a card to buy your own until you are a member for at least three years... I already know in Germany and the US things are quite different but I would still like to know how exactly it works in your contry or if your face similar problems outside US and EU territory.

Theme Park Holiday Light Effect

Hi, I work for a small theme park. A third party company built one of our new holiday displays.  It consists of 45 large 'ornaments ', each lit with an AC bulb. I've been asked to provide a way to control each one independently and create a pattern which will repeat.  Sometimes only one bulb is lit and sometimes up to 7 are on at the same time.  The problem is I'm looking at 45 AC plugs!  My thinking is to buy 45 solid state relays. Then can I hook them up to an Ardiuno? I know very little about Ardionos. Which model and how many? I would truly appreciate it if someone could help me get started. Thank you

How to put things on Favorites

At the top of the screen is You. When I click it the drop down menu shows Favorites. I would like to use this to store favorite Instructables but it doesn't seem to work. Is this a bug, or am I doing something wrong?   What are collections and collaborations? I've searched online for an instruction manual for Instructables but there does not seem to be one? In my opinion it is a big oversight that you don't have a big button at the top called something like "Get started with Instructables". Most annoying as the interface seems very confusing without an Instructable for it.

How do I separate gold from surrounding ores

I live near the site John Marshall discovered gold in 1848.  There is gold dust and particles everywhere!  Problem is that the gold is dust or fine powder form and the gold strongly adheres to it's surrounding ores.  Panning is tedious and not effective.  How can I separate the gold dust/powder from the other minerals?  I have heard using Auger Regis is effective, but cannot find anything on how to use it, purchase it, or make it myself.  Any suggestions/instructions on making or using auger regis; or any other more effective method of extracting the gold from the other minerals is greatly appreciated.

Energy with Seesaw system

In this sketch you will find that I have attached 10 shake flashlights on  the both side of a balanced seesaw system and this seesaw is moving with a 6 volt motor but  I have used 10 no. shake flashlights and each flashlight will produce only 2 volt as a output which will be less than input . On the first hand each flashlight is producing only 2 volt and on the second hand the total 10 no. flashlights systems are producing 20 volt . If we try this concept than input is more than output but if we add total output then it is greater than input. please answer me that will these flashlights will be light up or not as mass is not an issue in this device. Note(1)each flashlight is separate with another flashlight . (2)to move a balanced seesaw there is need of less energy or input. These flashlights are mounted permanently ,horizontally on the both Arms of a seesaw(making+ symbol and view my sketches) and this seesaw will move side to side just 2 to 4 centimeter only.remember we will only shake the only one arm of this seesaw with corner and flashlights will not slide as these are mounted permanently on the arm of this seesaw. suppose if a flashlight require 10 watt power to glow up then we will have to apply 20 watt so that so that this 20 watt input could also counter some mechanical loss also.but this 20 watt input will be sufficient to glow up these 10 flashlights as all flashlight are permanently attached on this seesaw so each will shake with equal force or applying force will be equally distributed in these flashlights..in other words we are giving 20 watt input and out put is 150 watt with these 10 no. flashlight.we can do it with our hand power to test it to shaking the seesaw.

Help! Please Donate More Common Sense!

It's not that I don't have common sense, It's because I think like this. I overthink things, when the answer is usually simple. Maybe I take things way too seriously. It probably took Brooklytonia about 20 seconds to read and figure this out... About a week ago, I uploaded an Instructable that I thought would be a HUGE hit. It wasn't. When my Instructable on Dimmable LED Workshop Lighting (Very High Efficiency) got featured in the Newsletter, it got 100K+ views. This is because it was at the top, and it was impossible to miss. When my Instructable on Insanely Bright LED Panel got featured in the newsletter, It got 40K+ views. It was at the bottom left on the email. I figured that it made sense. When my Instructable on Articulating 70W Spectrum-Balanced LED Panel got featured in the newsletter, it got ~10K views. This makes no sense! (I've changed the titles to what the staff changed them when they got featured in the newsletter. Not sure why I remember this...) Dimmable LED Workshop Lighting (Very High Efficiency) - Good title. Good thumbnail. Main Instructable - TONS of clicks - 3K views in less than 10 minutes Insanely Bright LED Panel - Okay title (not my fault!). Fairly good thumbnail. Located at the bottom left - Quite a bit of views Articulating 70W Spectrum-Balanced LED Panel - Good title. Good thumbnail*. Located in the middle. - Not a lot of clicks - 3K views in several hours. WHY? Of course there are several things that differ between Insanely Bright LED Panel and Articulating 70W Spectrum-Balanced LED Panel. But why such a difference? I mean-- I always compare the statistics of my I'bles, and try to make them better. It's usually hard to compare, and surprising. But why is there such a huge difference between two Instructables that are pretty similar? *I changed it a couple hours before it got featured in the newsletter, with the Instructables Pixlr editor. I know it turned ot a bit weird, but it was the best that I was able to do. The Pixlr site has better fonts, but the biggest on was still soooo small. Maybe I did something wrong. Images of before and after:

Here's a thing I want, but have no idea how to build: THE INDEPENDENT KEYBOARD It doesn't care about computers! It save to itself! It's portable! There must be some way to build a keyboard that, once you turn it on, saves whatever inputs are typed to a plain text file on a thumb drive or SD card. Ideally, there'd be an on-off switch. When it's on, it's "recording" all inputs. Then you simply pull out the storage unit, plug that into a computer, and have your raw text. Any thoughts on how to pursue creating something like this?
