50 Watt LED

50 Watt LED

I mentioned recently that I’m planning to attempt to retrofit a Kodak Carousel slide projector into a slide digitizer. I’ve begun to make purchases towards that end. I already have a few projectors. The most complicated parts, which are anything to do with electronics, will be replacing the light source. The 300 watt halogen bulb is very bright and very hot. LEDs generate some heat, as well, but not as much. This is the light source I have picked. It’s 50 watts and should give me a nice, even illumination. I’ll put some pearled glass between it and the slide, to further even things out. I also bought a heat sink with an attached fan and a driver for the light that runs on household current.

Computer Carcasses

Over the years, I’ve collected a pretty impressive collection of computer remains. Some were my primary computer at one time or another. Others were given to me to see if I could repair them and turned out to be beyond repair. Still others were servers of some kind. One was a firewall, a few had been web or mail servers. All of them, however, were well past their sell by date and needed to be hauled away. I took the hard drives out of them and will deal with those separately. In addition to the 13 computers in this photograph, there was a large box of peripheral cards (including three 33.6kbps modems), another box full of cables, an old CRT monitor, and a few miscellaneous items. These all went to the electronic recycling station at our local recycling center.
