Picked up the medium size hard case on an amazon deal. I like the foam, I wish I could get that kind of foam for protecting my other gear.
Canning shelves finished
Canning shelves
This weekend’s project was to create specialized shelving that my wonderful wife can store her full and empty canning jars. The shelves would be in the garage, so they do not have to look pretty, but they do have to be very durable. I used 2×4’s, 1/2 CDX plywood, and my Kreg pocket hole jig. The 2.5″ Kreg zinc coated screws are the right length for use with 2×4’s. They make a nice clean joint and are very strong. I didn’t not glue these, but you can use Gorilla glue for even more strength.
These shelves are set off the floor, so the bottom row of jars will not freeze. There are three shelves total. The top is not yet finished. All the shelves have/will have a guard fence to keep the jars from falling off. I plan to use webbing or some kind of stretchy net on the front of the shelves.
My Favorites of 2014
Services:
Wonderlist: This cloud based to-do list is awesome. It has fantastic clients on iOS and Android. I use it to manage home, work, and hobby. I use the to-do entries to capture ideas for projects I want to build later.
Crashplan: I played with Crashplan’s non-cloud backup abilities and fell in love with it. We now subscribe to the family backup plan and supplement it with a local backup server. Our data is backed up twice! Linux clients are a big win here. The only downside to this is that the clients are written in Java and a little slow.
Google Play All Music Access: My friend Ivan Godwin got the discount “first adopters” rate for All Music Access. Since he started talking about it, I decided to try it. Having access to a seriously large music catalog has changed how I approach music. I try almost all the new music that comes out on a weekly basis. I still have a core play list of work and exercise music, but now I frequently add to it. I’ve found very bands / albums that are in Google’s catalog.
Books:
Effective Modern C++ (2014 Scott Meyers): After a long hiatus from C++ development, I picked it up again in 2013. This new version of a classic book is reasonable concise and captures a lot of the new ideas and concepts that are in modern C++. It’s not just limited to the syntax, but also covers some of the new standard library features. You can buy a copy from Amazon or read it on O’Reilly Safari.
Gear:
Sony Alpha a6000 : I traded in a Sony NEX 3N for the A6000. The NEX 3N is slow and the kit lens is really not even good for a beginner. The A6000 is a huge step up. The quality, just from a fit and feel is far superior. The operational speed of the camera is light years ahead. I’ve only had the A6000 for a few months, but I don’t regret upgrading. I skipped the kit lens coupled the camera body with a Sigma 30mm prime lens.
MiniVNA Pro: I picked up this USB network analyzer to round out the analytical instrumentation on my work bench. This device connects via USB or Bluetooth and provides two-port analysis of passive RF circuits. The Windows desktop app is a bit clunky, but the price is right. My only complaint is that the unit should ship with the three termination options used for calibration by default.
Teensy 3.1: Small and fast ARM based Arduino compatible dev board. Fits directly onto a breadboard. This was my favorite until the Particle Photon came out.
Gregory Z35 Backpack: I needed a lightweight backpack for SOTA and hiking. I read some really great reviews about this pack’s suspension and ventilation. It’s all true: the ventilation is marvelous. I sweat a lot when hiking. This pack has a generous air channel right where your spine goes. With radio gear, I typically load this up with twenty pounds of gear. The Z35’s suspension has a wide, padded waist strap. This strap is better than most all packs in the same size class. I pair the Z35 with a Sea to Summit sil-nylon pack cover.
Wigwam Rebel Fusion Trekker Socks: I’m picky about socks. I tend to stay from most cotton clothes, especially cotton socks. This is a lesson that was instilled in me during several Boy Scout trips to Tuolemne Meadews. Cotton is death! These socks are 37% wool and the remainder is mostly nylon. Pure wool socks tend to make my feet sweat. The Trekker socks breath much nicer, and they stretch with your feet. I wear these around the house, to work, and even as liners inside heavily wool hiking socks.
Uni Kuru Toga Mechanical Pencil: Hands down the best sub $10 mechanical pencil on the market. The auto-rotation mechanism actually works. The body feels nice and heavy; and there is no play in the tip.

Sparkfun geiger counter
Super short weekend project: hookup my Sparkfun geiger counter and start reading counts per minute.
With the protective cap on (the tube will only read gamma and beta radiation) I see 6 to 16 counts per minute. I do not have a radiation source to calculate the conversion coefficient to micro Sieverts.
On a side note, I attached the board on a VMware ESXi machine and read the raw data with a python script. I’ll create a feed here soon.
Direct conversion receiver using DDS
I’m working on a test bed transceiver. I’ve wanted something that is modular enough, that I can swap in and out sections to test new designs (and just have fun). This is a Teensy 3.1 with a cheap Chinese DDS board that contains an AD8550. I am using one of my LM380 audio boards, a Sparkfun Serial two line LCD, and a few rotary encoders for tuning.
