For whatever reason, some pictures decide not to load. I see the errors in my log on the server, as HTTP Code 304. Something seems to be happening in the voodoo my shared host uses to make my domain seem to be on its own box … “virtual servers”. Because I’m lazy I’ve been using relative links to my pictures, rather than absolute links; this doesn’t seem to play well with the hosts voodoo, so, I’ll be using absolute links from now on and hope that resolves things.
If a pic isn’t loading for you, please leave a comment or shoot me an email (gordonthree at gmail dot com).
*edit* thanks to linear for pointing out that 304 isn’t an error, it just means the content hasn’t changed… so I’m not sure what the cause was for those of you who mentioned you couldn’t see a picture – hopefully whatever it was, it stays fixed!
I’ve created a new page under Technology and Projects. Digging through my samples box, I came across the MAX1668 from Dallas-Maxim.
The 1668 is a five channel temperature probe with a serial interface. My final goal for this project is to hook the 1668 up to a large VFD display for monitoring temperatures.
Check it out … there are a ton of pictures, so dialup beware!
Well… I probably won’t be posting any more project write-ups until next weekend, but I’ve noticed this brand new site is getting a few visitors already!
If y’all have any questions, shoot me an email at gordonthree at gmail dot com … or drop by http://forums.linear1.org

Here’s a cheap incandescent garden / landscape light I retrofitted with 4 RGB leds. It works OK, but the retrofit module is difficult to assemble without a proper pc-board and there are problems with diffusing the light properly.
I’ll revisit this project sooner or later
This breadboard is the first time I had dealt with high / super flux leds… otherwise refered to piranha or ufo package leds.
These came from www.lsdiodes.com and have a viewing angle of 45 deg… it makes them super tremendously bright looking indicators, and probably would work great for tail lights and such.
The piranha led has the chip or die mounted on a large heatsink connected to the anode … the cathode is also a heavy duty looking assembly, but its only connection to the die is a hair thin gold wire. The piranha led is an illumination grade led; it is designed to have a very high light output and be installed in close proximity to other leds of its kind. The large heatsink carries heat away from the die, but you still need to do something with that heat. The PCB board should have as much copper on it as you can fit, and the traces feeding the anode should be as beefy as possible so they can conduct heat from the pins.
