We like to have a lot of fun around here, but we also know that there are times to get serious and use our semi-prominent position to rally our readers around a good cause.

The best part? As its name suggests, DonorsChoose allows you to allocate your donation however you please; so instead of contributing to the general "Engadget fund," you're actually giving directly to one or more programs impacting high-need public schools.

You have until October 31st to make a donation -- either by clicking here or on the Read link below -- and we sincerely hope that you'll consider helping out these projects that really do have a chance to give kids a better future. We'll keep you updated with Team Engadget's progress, and while it would be almost criminal to guarantee every reader a new HDTV if we meet our goals, well...

Because we're all such huge philanthropists, I'm sure we will be lining up to purchase the 26, 32 and 37 inch LCD HDTV's NuVision is putting up for auction in conjunction with The Light Foundation. Besides their 1366x768 resolutions and 1000:1 contrast ratios, the 2 larger TV's will also be signed by members of the Patriots football team that charity founder Matt Light plays for. To make it even better, any winning bidders with 100 miles of the Patriots home stadium will have the sets installed and set up for free by Home Smart Home.

The Light Foundation helps support youth oriented non-profit organizations in Ohio and Boston.

The TV specs:

• 10ms response time
• 500cd/M2 brightness
• 16:9 widescreen

Giving back to the community, football and HDTV's. That's a win-win-win. Auctions end December 29th.
