More 434MHz stuff to look at later

Acurite #0899 self emptying rain gauge – at Amazon

Blog post on reversing the signal from Acurite temperature sensors; may be similar for the rain gauges.  Also mentions the RTL SDR.  Probably wouldn’t be bad to have.

Another blog post regarding reading the Acurite 5n1 station.  Possible that part of this will already cover the rain gauge.  Also discusses SDR and mentions the rtl_433 tool.

This blog post looks like rtl_433 supports the Acurite 896 decode natively, so if the protocol is similar or the same it may be simple.

RTL Software Defined Radio – at Amazon – seems like it’s probably a decent model, some good reviews.  Looks like there’s a little more to it than just “buy this and set up the software”.

Bought a cheap receiver off of eBay from Hong Kong for $7.31 (original listing).

Also, here was an Instructable about making a cheap combination RF/Bluetooth/433 MHz remote using an Arduino.

Stellar garage organization

This guy has the best garage organization I have ever seen.  Definitely will be taking some ideas from this page for tool and garage organization.

Recent mini-PC/router devices of interest

Posted January 5, 2015 By Landis V

RockTek RT-A1, priced at $65 on NewEgg Flash on 1/5/15.  Quad core, HDMI output up to 2048 x 1536.  Appears to be only a 10/100 ethernet, but has a couple of USBs to which GigE adapters could be connected for up to 480Mbit theoretical throughput.   Also has a composite video out, which could theoretically be paired with one of these 4.3″ LCD “backup camera” displays for a convenient method to apply updates, etc.  Caveat is that there does not seem to be much hackery on it to run Linux natively, but it is tempting to pick one or two up to play with and see what could be done.
Also ran across this Foxconn AT-5570 (manufacturer page here, also on sale at NewEgg Flash for $90, though it would need to have RAM and storage added).  Higher price and lower performance would make this somewhat less appealing.

The Foxconn was perhaps most interesting because it led me to the Jetway motherboards with multiport ethernet daughterboards.  This auction page had a six port GigE model.  The four port daughterboard is the Jetway ADE4RTLANG, and several of the Jetway mini-ITX mainboards include dual ethernet ports natively.  Quite a bit higher priced, but might prove useful at some time.

Also interesting was the Odroid-C1 currently selling at the same price as the RPi, and their intro/getting started kit with the required SD card as well as a breakout board and some basic electronic components to get familiar with the device is on sale for under $70 through January 7th when paying with PayPal.  The C1 is, I believe, almost pin-compliant with the header on the RPi.  It has a quad core 1.5GHz processor, 1GB DDR3, and a gigabit ethernet interface.

Pretty good board list, including a couple with dual ethernets, which is something I’ve been wanting to have.
