SV: [OT] What to do with old CRTs?
Hi, I remember seeing something cool... I think it was made from old screens, think TV's would have been a tad to big... A guy makes the coolest bowls out of old screens. He cuts them, and then files the edges smooth... Real cool bowls to use for all kinds of things, or just to have as decoration on a table... Don't know if this is something anybody here would be interested in, but... :) I know I would have loved one of those bowls, they really looked cool, super for a modern design home... But they were really, really expensive, considered as designer bowls... Aase :) -- G-Books is sponsored by http://lowendmac.com/ and...

SV: [OT] What to do with old CRTs?
Hi Rick, Ooooh, I loved those monitors too When I was in college, I switched from a stationary PC to a PowerBook, in 1992. Then a while after, I was having my finals. When I had tests, the school set up a computer for me in a separate room. After switching, I asked if it would be possible to get a Mac, but didn't really think they could do it, since the college only used PC's. But when I came, they had set up a Mac with one of those screens. After that, I got that screen every time I had a test. I just loved it, especially for such a situation, I often produced around 20 pages for a full day exam. If others who also used computers sat in the same room, they all had PC's with ordinary screens, they envied my screen so bad, because they had to take print-outs all the time... With that screen, I never felt a need to do that, I just printed when I was done... I would still say that those screens are perfect for those who write a lot... For black and white writing, they sure do the trick and then some... Would be neat with an LCD like that... Aase :) On May 26, 2005, at 10:55 AM, Rick McCutcheon wrote: Hear, hear!

[OT] What to do with old CRTs?
Not really on topic, but since I didn't have any other place to ask... I have my Apple Studio Display 17 that stopped displaying a picture last week. I did replace it with a 19 LCD display, so I'm not really trying to repair it. However, I already had an Apple Studio Display 21 that stopped working last year. So, I have 2 of those big CRTs taking space and I was wondering what to do with them. I'm pretty sure that the problem is with the power supply and somebody more experienced with televisions and CRTs might be able to repair them. I'm not looking to repair them, just to get rid of them. I was thinking that I could maybe offer them on the LEM-Swap list. Any suggestion?

Re: [OT] What to do with old CRTs?
Hi Laurent, CRTs are nasty items. An average 17 monitor holds 7.5 pounds of lead (protecting you from those radioactive isotopes). In your CRT computer monitor there is also phosphorous, cadmium, barium and mercury. As a product, these hazardous materials are safely sealed. (The lead is imbedded in the glass, for instance). However, when the monitor is sent to a landfill, heavy equipment is used to compact the waste. This crushing and smashing of the waste causes the hazardous materials to be released and a leaching process can occur as a result of CRT breakage. These toxic materials will probably find their way into our water supply. When the glass is crushed by trash facilities, the lead-bearing particles and phosphors become an airborne hazard. Some states have banned CRT disposal in landfills. Here in Oregon, we have an interim policy, meaning, folks are discouraged from dumping monitors. Our nonprofit takes in 20-100 monitors a week. We gift working monitors with the computers we give away, we sell some in our thrift store, and we recycle the monitors that are too small, to old, or broken. Besides our rent of $4500.00 a month, monitor recycling fees are our biggest expense. We are committed to not dumping in international back yards-a VERY big nasty secret within the recycling industry. Because we specialize in Macintosh, we are faced with an additional problem. Apple manufactures the wonderful all in one (AIO) computer. Monitor recyclers will not accept AIOs (more hardware to deal with, more screws in the take apart). Unless we are willing to pay $20.00 a piece to recycle the AIOs we are stuck with 00s and 100s of nonplacable machines. So, we have started a program were we dismantle the AIOs and recycle the bare CRTs. This lowers our cost and makes it possible to continue to work with schools (the biggest generator of AIO waste because they are the biggest buyer of them). I am delighted you are considering the impact of the dead monitor on your environment. Apple recently got some VERY bad press for not designing their products for recycability. Panasonic is really moving on this, so are a few big manufacturers. If you recycle your monitor with a responsible nonprofit or for-profit business, you can know that the material won't be dumped in other countries and the material will be reused. Lead from monitors is used to make new batteries, the glass may be used for road surfaces, the plastic may be used in your car dashboard, or new computer plastics, or maybe that new Barbie doll in the shop window. LEM list members ship us their monitors on a regular basis. If you ship, remember to include the $15.00 handling fee (whether the monitor works or not). raino On 5/26/05 8:47 AM, Laurent Daudelin [EMAIL PROTECTED] wrote: Not really on topic, but since I didn't have any other place to ask...

Re: [OT] What to do with old CRTs?
Shoot, I mistyped-I meant to type photon. There is radioactive photon waves shooting out of the electron guns. The lead is embedded in the glass to protect you from the photons. Any magnetic field is radioactive. CRTs also have lead in the soldering, the capacitors, and often lead is sprayed on the boards as a fire retardant. LCDs have there own issues, one being the mercury contained in the backlight. raino On 5/26/05 12:31 PM, Rick McCutcheon [EMAIL PROTECTED] wrote: On 26-May-05, at 1:24 PM, Bruce Johnson wrote: On May 26, 2005, at 10:40 AM, [EMAIL PROTECTED] wrote: CRTs are nasty items.

I've got a lovely old monochrome portrait monitor that I used for a long time with a IIci because I love to see a whole page up on the screen. I've still got it packed away, moved it across the continent a couple of times (with my wife smiling as I lug it to the truck because I don't want it banged, even though it now has a crack in one corner of the front bezel) but I'll never use it again. I just can't bear to throw it away. Maybe I should have it put in the casket with me?

We here in Albuquerque (home of Sandia National Labs and not too far from Los Alamos National Labs) had our very first computer equipment drop off day this past fall. Our Mayor, Martin Chavez donned his gloves and pitched in that day, hauling computers from cars, vans, SUVs and pickups. My household unloaded a ton of CRTs, non-working and geriatric computers and peripherals that day! And the city filled three 18-wheeler-sized truck trailers!

The lead does shield (partially) the artificial radiation produced by a 10-25KV electron beam hitting the screen. Besides the lead is inside the sweep coils, kind of hard to shield something that way. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting I'm a designated driver on the Information Super Highway -- G-Books is sponsored by http://lowendmac.com/ and...

LCDs only use a fraction of the power of the same sized CRT. And, not to lose the main point, approx. 7.5 pounds of lead per monitor means there is a lot of lead going into landfill sites! I don't know of anything in an LCD display that is nearly as bad as the lead. I don't think there is anything. No one really seemed to care about what was in a CRT monitor until LCDs provided an alternative.

Well, actually the X-ray E-field radiation, not H fields, but Our Buddy Mr. Maxwell explained all that, right? [As I wrap my right hand.. http://www.innopro.de/maxwell_hands_all.htm] Well, actually E-M radiation. It's caused by electrons above some voltage hitting a ground potential giving up their energy in the form of X-Rays. Medical diagnostic X-Rays are somewhere around 100KV. Theraputic X-Rays run from 4 to 30 MV and require a radio-isotope or particle accelerator.

The lead is embedded in the glass to protect you from the photons. Any magnetic field is radioactive. CRTs also have lead in the soldering, the capacitors, and often lead is sprayed on the boards as a fire retardant. Time to head back to physics class but stay awake this time. No, magnetic fields are not radioactive. Yes there is lead in the solder (although it's been / being replaced). There may be some small amount in the caps but not much. It isn't sprayed on the boards, that would be nuts. While current theory says that light exists both as a wave and a particle you usually refer to it as one or the other, not both as in photon waves. In any event they don't come out of the electron gun(s) but from the screen when the electron strikes the screen. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting I'm a designated driver on the Information Super Highway -- G-Books is sponsored by http://lowendmac.com/ and...
