Not exactly sure what I would do with it, but its very cool for those that need
 
Just learned about +Outernet and they have office in #Chicago :

Anyone tried loading pfsense on a Zotac ZBox? The cd boots but the installer keeps complaining about a SCSI driver issue and fails. I tried both 2.2 and a few of the daily compiles just to check. All give the same issue.

Anyone have experience with these and a Raspberry Pi? http://amzn.to/1NxX06K I am trying to use it with a A-D converter and really I get nothing useful for readings. Tried a multimeter and the transformer but that too gives me nothing useful. End goal - I want to know when a 110V and a 220V pump is either on, or off. I don't care so much about the current draw I just want status.

I have a clamp current sensing tool you could borrow, but unless a load is big I've never seen it read well

Anyone else with a Pi on WIFI had their Wifi just go away? Been running a Model A on my desk for about 2 weeks now. Im still waiting for some parts and I have to build a case. It has a USB WiFi. Twice this week the wifi just dropped. I had to do an "ifup wlan0" to bring it back. Anyone else seen this? No errors in the logs, nothing really to say why it dropped. I think when I put this in its final destination I might have to go wired ethernet...

I''m building a Pi to watch the usage of my sump and well pumps. If I check power status every second, I don't want to actually store that many data points. I figured I would store only the change points (off to on, on to off). RRDTool doesn't seem the right way for this. Any suggestions? #raspberrypi

Well, you need to store a state every given period (hour), and then the change from that point at times...

Thanks to http://pyserial.sourceforge.net/shortintro.html#opening-serial-ports and the RaspberryPi, I now have a scrolling board I can talk to. Next up, the Traffic Light!  Eventually this will be hooked into either Nagios or OpenNMS, or whatever other monitoring system we decide to go with.

I want to edit the startup on a CentOS CD. I've already customized the disk itself but I want to grub to include a few extra options on boot (and a few less choices on the menu). Editing grub.conf didn't seem to do it. Is there something else i need to do before I do a mkisofs with my new cd file tree? (CentOS6.7 iso)

Looking to see if anyone tried current sensing with a raspberry pi. Before I purchase two of these: http://www.amazon.com/SCT-013-000-Non-invasive-Current-Sensor-Transformer/dp/B008ASXVL4/ref=sr_1_1?s=industrial&ie=UTF8&qid=1420409783&sr=1-1&keywords=current+sensor I was hoping someone could offer advice on non-invasive current sensors. I am looking to monitor a basement sump pump and a well pump, high amp A/C power.   #raspberrypi  +Raspberry Pi

I got an USB->RS485 adaptor for my RasperryPi project on Amazon. It came with no documentation. I looked up the contact info for the vendor to email and ask for some spec sheet or something only to discover they sell a really wide variety of items from LED lights to dildos. Something tells me I am not getting a spec sheet.

I have the MFG number now, I can probably find something online somewhere. Hopefully it will solve the "connect the Pi to the scrolling board" issue.
