Getting there…

So I ran into a hiccup on the Pi.

Having updated the firmware and running Realtek 8192CU usb dongle for wifi, after I got Motion working, I would put the Pi outside, only to have the connection on it go to sleep, or something.

A day of googling potential power issues (a trend when dealing with the Pi it seems)…installing the LiPo rider board (which compensates for power disruptions from solar power fluctuations) …no dice.

I tested the power supplies and discovered even with appropriate voltage levels indoors the Pi was dropping packets over wifi like crazy. Boot file modifications didn’t help.

So this morning I reflashed the sdcard to a Raspian image from January, explicitly did NOT RPI-Update, and now the same wifi dongle works perfectly. Kernel conflict with the 8192 chipset? Not sure.

It’s stable now, and I’m running the Pi on the solar-fed battery overnight to test before I throw a load on it with motion detection. In the meantime, a few pictures…

wpid-wp-1402968371989.jpegUsing an outdoor outlet cover and backing to protect the Pi from the elements. I tried some otterbox-style cases I had around, but found this location gets too warm for super-tight enclosures that I used in my Humidity-Pi project. Also the thing was like 7 bucks total including the backplate, and it works pretty well.

I have to position the Pi slighly diagonal, but it’s not awkward; I can open the lid with ease, and even with the frosted texture on the cover, I can make out the activity of the LED’s when I need to.

The motorcycle starter battery has been working pretty well as a solar battery.

I haven’t yet decided on a permanent housing for the battery and the Li-Po rider and wiring, I’m looking into something that ventilates a little better than what I started with, but something that won’t take in too much moisture as Florida moves into monsoon season…

 

Tomorrow I’ll re-install Motion and see if I can get motion detection going, and snap some hungry Blue Jays in action….

Raspberry Pi Book Hack

Nothing new here, but I was very inspired  by unusual cases others have put together.  This is one of those ‘book safe’ style books you can get at home decor stores (cough, cough, Old Time Pottery).

I dremel’d a 3 inch by 3/4 inch slot in the long side ‘page-edge’ of the fake book.

I’ll warn you,  this particular “book” was made of  dense particle board material and seriously took a while to saw, drill then gouge out the opening. I’ll look for a lighter material for my next attempt. I couldn’t bring myself to deface a real book for this. :)

This will eventually interface with my SDR-IQ using opensource code from the Ghpsdr3-Alex project.

Edit: Looks like the Pi Won’t be powerful enough for handling the SDR-iq, but I have an RTLSDR on the way to take a gander at that, Wish me luck!
