A brief distraction: Robots in my crawlspace
« on: January 19, 2005, 01:51:32 AM »
As it remains my duty to provide y'all with the occasional 5 minutes worth of distraction, I have an updated page.  

A couple weeks ago I mentioned I had put a camera on my tank and sent it under the house to explore.  Well, I finally got around to posting some pictures and video of the adventure that you might find somewhat entertaining.

If any of you decide to do your own robo-archeological expeditions, be sure to share.

HUZZAH! Now all you need to do is disassemble the tank and install rheostats so you can lower the speed to a less breakneck pace.

Hi there Chairboy. Turns out I've been trying some of these cameras while studying a bussiness relationship with a chinese company, and I think you may want to try this model:



You can find it cheap in ebay and the low light characteristics are phenomenal.

Edit: D'oh! Fenomenal :rolleyes:

Is this a ring of IR LED near the lens ?
They don't have a good (or perhaps not at all) filter in front of the captor :)

It is a ring of IR leds and a photoresistor. It does overexpose people in close range, but for most uses, the results are surprisingly good.

I was pretty sure it was a ring light as it's pretty difficult to have performances in low light condition with a lens having a frontal diameter so small.
Just look how huge is a 50mm/f1
like the noctilux :



or the Cannon
