Pond lining question.?

The moulded liner in my pond has given up - it's cracking faster than I can patch, so I'm going to re-line it. I have a suitable flexible liner, but my question is: Should I rip out the existing liner and line from scratch, or should I fit the liner inside the rigid liner? The latter will be easier, but would the former be "better"?

Line counting sensor?

I have a group (20) of small robots that need to all end on a certain line in a grid. My question is how can I get each car to count the number of lines it crosses and when it reaches the right number it stops. The problem is I have a budget of $75 dollars to make the guidance for every car. If there was maybe some sort of central controller that would work for each or maybe it is just cheep enough to make a simple set-up for each one. Any comments or questions would be much appreciated.

Rectification of line voltage?

I need to get 230V DC for controlling the brightness of the bulb using a mosfet transistor. The problem is that the rectified line voltage'll get 230 * sqrt (2) = 325 V .. it is too much. I didn't find a transformer AC / AC 230/160 V or step-down IO DC / DC 320/230 V on a market. How can it be solved? Sorry for my english. Thank you for answer.

Plot a diagonal line? Answered

PD17200,11600; i am sure I should know this. I need to plot a diagonal line from 17200 to 11600  Obviously there are more X points than Y points. Is there a handy algorithm to work out how may X points to ploy against Y? My current solution is to extract the difference - 5600 and divide the Y by that  11600/5600 = 2.1 So you plot 2.1 Y points for every X point. Somehow this seems wrong? i am sure I should know this.

Is it possible to create a horizontal line on TV screen to be able to move it ???

Hi ... I would like to ask, if you know a way how to create a thin, horizontal line on your TV screen by using a device ??? Device is NOT a string, scratch on the screen, line with a pen ... (and not even PC)... by DEVICE I mean an circuit (micro controller, resistors...etc) ... and I should be able to move the line to any position I want (up/down). EDIT : the line should be projected on the screen without having an effect on the background. So that you could watch a movie and see the line as well. A better example are the "driving lines" on a rear camera ( This is, what I'm looking after. Have you ever come in touch with something like this, or do you have an idea, how to create it ???

Can i line in thru the cd player on an older boombox ?i

I have a GE boombox from the late 80's early 90's in which the cd player stopped working years ago.I have been looking at the instructions on this site for line in thru the cassete player and was curious if it is possible to do the same thing except do it thru the cd lines going to the board .It appears to me that with most of the instructions i have read about the cassete conversion is that the cassete drive motor still runs after this conversion which sucks quit a bit of juice,which may not seem like a big deal to most but i go on canoe trips for 3-5 days at a time when no power is available other than the batteries I bring on the trip so it would be nice to line in and not have any motors that are not necessary running. If not i will use one of the great tutorials for the cassete way of doing it. Thanks dave

What IR source & two terminal Photo transistor can be clubbed to replace either QRD1114 or CNY70 reflective sensor pkg?

I'm referring to - Building of a SPURT BOT(a simple line following robot) submitted by ignoblegnome (See I'm building one for my cousin who's in the 7th grade & found this to be the most simplest & one that looks like its been made by a kid.           It looks so, as it has the least number of electronic components. But unfortunately i have been unable to find both QRD1114 & CNY70 reflective sensor packages. While going through the comments section, i saw a comment by the author himself saying that the package can be replaced with an IR LED & a 2 terminal Photo transistor which happen to be the same components that make up both QRD1114 & CNY70 packages. I would be extremely thankful to fellow users if they could mention the exact part/component number of the IR LED & a 2 terminal photo transistor that can be clubbed & used instead of QRD1114/CNY70 for the same voltage rating & circuit used in the instructable mentioned above. I need this info ASAP, THANKS a TON & kindly forgive me for my bad grammar.

line distance in the new editor

Hey! i'm not a big fan of the (now compulsory) new editor (yet), but since it is an inherent qualitiy of humanity to be sceptical towards all things changing don't mind that. BUT: i have a really big problem with the line spacing (i hope i'm using the proper terms for all this formatting related things...) Here, it still works fine: if i want to create a newline, that is if i want to create for exampple a list of things that contains only one word per line the line spacing between those words is still just the same than when i just type in an endless row of words and if i reach the end of the line it starts automatically in in new one. if i use the new editor though, if i do the list thing, (if i push "enter" after i typed in something) all of a sudden the line spacing is about 1,5 times as big as in normal text and i can't change that. this really bugs me, as it doesn't look very good, but it also makes a text very unclear an confusing and if you have to write a long list of things, for example when explaining what things you need for an instructable, the text will appear very long and things that before fitted nicely on a computer screen have now to be scrolled down. furthermore, it is not really possible anymore to distinguish between a new paragraph (that starts when leaving an empty line between the text), or if you leave an empty line, you have a really huge gap between text parts that just looks weird and bad. so please, is there a way to fix this? is there a button to push to prevent the increase in line spacing when i push "enter"? that would be really awesome!

Issue with line spacing in lists

I'm having a really annoying issue with formatting while writing Instructables. I'm sure someone else has complained before, but there's little else for me to do besides bringing attention to the issue. When writing instructables on a PC (Chrome, Windows 10), I'm having very annoying issues with line spacing when copying paste from another window. Most of the time it is simply copying text from some prior instructable I've wrote. It is especially problematic in lists. The issue is that sometimes the spacing between lines doubles after copying text, and even in subsequent lines the issue persists. This makes consistent formatting impossible. It seems to be due to copying the text from other formatted sources, but there are still conflicts when I try to copy and paste unformatted text. I'm not exactly sure what the trigger for the issue is. I have posted an image where no space between lines exists for the first 3 bullets of the list, but for the following lines (after pasting the third bullet point), all the spacing is double spaced. It does appear that it shows correctly (consistent formatting) when the instructable is posted and viewed online from a PC, but when viewed on a mobile device, the formatting gets messed up again and shows inconsistently. The issue also seems to sometimes involve different font sizing. Anyway, I just wanted to mention this since I'm finding it very annoying. I'd want to be able to have more control on the formatting, and also being able to copy formatted text (bold, underline...) from other prior instructables. But for the moment with just not having to deal with the line spacing option I'd be satisfied.

Straight line art - what is the technical name?

I remember back in 2nd, 3rd, 4th, and I believe even 5th grade, when I was in a gifted program, we had to draw. We drew only straight lines, and when we did it right, it made a curve. We would get a paper with 2 lines, connected at a vertex, at a 90 degree angle. We would draw points every centimeter or so, and connect the points, far to close, far to close. (It's hard to explain.) I'm searching for it on the Internet, but I can't seem to find the right word. Does anyone know it? Thanks, and if it turns out all good, expect an Instructable on it mid- to late October.
