Poly, PETG, Acrylic? How to tell?

Hi all! First, this is my first post to the forums. Hi. :) I have a friend with a laser cutter, and he said that he can only cut Acrylic or PETG. No Polly. First, why is that? And second, I already have some plastic, so how can I tell what kind it is? I bought it a long time ago... I'd rather not buy more plastic if I can help it, but I will if necessary. Thanks! ~Mark

I stole some poly fill/insulation shit out of a old pair of speakers that are waiting for some new drivers and I stuffed it in my subwoofer box. It doesn't sound like it's going to explode as much as it did before (it's a rather "rickety" box). But I did some googleing and it can overpower a speaker or something? I won't hurt my sub will I? -Punk

how to poly a guitar amp a light color?

I would like to keep my home-made guitar amp a light color. and i am having problems finding the right polyeurathane for it.  it is a very whitish wood, and it does not have any knots, and i like the white color of it. and when i put just plain poly on a scrap of wood, it turned a disgusting yellow. i dont really want that! haha so i wonder if there is a way to keep that beautiful white color on the amp, but still have poly on it. because if i dont poly the amp, it is going to get destroyed by water, dust, and it will, of course, get beat up by random things (little sisters....haha jk). sooo, i just wondered.

Closed system-conductive heating of pool with solar

Hi clever folks, We've been reading the Instructables for making solar hot water systems to heat a swimming pool (4000 litres) in our very shaded backyard (in Australia). We like the idea of using a coil of black poly pipe or garden hose laid out in the sun to heat up and then pumping this through the pool during the day, but the thought of bacteria building up in the pipe has struck fear in us! Sooooo....we may need another plan. I've read way too much on Legionalla and now think it would be safer to have a closed system. What we had in mind is a network of thin poly pipe either in 2D or 3D that would float (or be weighted slightly to sit in a good portion of the water "column"in the pool) and connect this to a long length of black polypipe that would receive solar heating. Obviously this would be a heating system that takes place when no one is using the pool (i.e. when the kids are at school). We'd keep a pool blanket on to insulate it too. When someone wants to use the pool, which would typically be in the evening for us, we'd remove this so-called radiator. Hopefully it would not be too heavy as the thin poly pipe network will be filled with water. Hmmm...so tempting to try it this weekend. We just would love to hear from folks that have knowledge to share on these topics. Thank you, Elise

Charge unprotected lipoly with desktop power supply? Answered

I have a few, almost dead 700ma li-polies taken from a macbook battery that would not charge. I have no formal Li-Poly charger, and most commercial charger will refuse to charge these batteries anyway- because most of them are lower than 2.7v right now. I wanted to see if I could revive these, which I have read can be done, using constant voltage and current.  My problem is how to charge these using a common desktop power supply. My setup right now is a charger set on 3.7v, multimeter in parallel (to measure the cell voltage), and a current of 20ma. So far, nothing dramatic has happened thus far. Thing is, the "shorted" light on my power supply is on, and the voltage says its around 2.8v right now (rising slowly). Is this just due to the battery charging? I mean, is this behavior normal for an unprotected cell charging on a power supply?  Also, please note that I do know what lipolys can do. I am not just gonna hook this thing up to 20v and leave to go to town. I am monitoring it, and have it in a large, thick plastic box that is 2ft from a door. I will not leave it on unsupervised.
