Thanks. I will look into this.

I would like a short-term backup power supply for an SBC4. It needn't last more than a minute or two. The idea is just to let the SBC send a notification of a power failure (detected on a Digital Input). Ideally, this would be a small Li-ion or Lipo battery and it would just float on the power suppl...

And, as usually happens, as soon as I post a question, I find the answer. The following item, with the 0-5v option, looks like what I want. Fingers crossed, and I'll report back when I get it hooked up.

I am looking for an outdoor humidity sensor. I have used the, now discontinued, HM1500LF -- it worked, but it failed after a year or so, I burned through 2 of them. I also tried the HUM1001. Supposedly it will work outside in a protected area. I guess my area wasn't protected enough. The board corro...

If I press 1, or 3, I reach a voice mailbox for some unnamed person who is "unable to come to the phone right now." Pressing 2 gets me a recording with no way to reach someone. Dialing an extension results in a message saying the extension is busy.

I would like to use a camera for still frame acquisition for external processing via <ipaddr>:81/static_simple.html Since the usage will be infrequent, I would like to disable the camera when it is not in use. So, my questions. On the SBC's webcam control page, does disabling the camera actually cut...

Unless you have some particular need or reason, you should be using python 3.x. Working on a new project and a new installation with python 2.7 is just begging problems.

Update: I think I have figured out why reflected light had not worked for me in the past. Very simply, when using IR devices, the amount of light is the minimum needed to calculate the distance to an object. And, when I tried an 1127 light sensor with two white LEDs as a light source, the light leve...
