EDC 2013

I made an EDC post back in 2009 that is now woefully out of date. I’ve had the little pen case thing I carry come up a couple times recently, as people are more in to this sort of thing now, and thought I should update.

EDC2013

A – Belt, 1:00- Generic suitably sized phone holster, with clearance for the headphone jack cut out.
B – In the holster – T-Mobile MyTouch 4G Slide (AKA HTC Doubleshot), currently running a recent unofficial CM9 build. Detailed impressions here.
C – Wrist – My over-decade-old Fossil Blue AM-3314. It’s a dual face (analog/digital), and makes a good grounding strap.
D – Clipped in to right front pocket – Keys, on a snap-hook. RFID fob for the office.
E – Left Front Pocket – Wallet. Leather, with card slots, and an integrated coin pouch.
F – Right Front Pocket – Self-made pocket organizer, holds Black, Blue and Red 0.5mm Uniball Vision Elites, 0.7MM mechanical pencil, Flash drive, and Chap stick. Discussed below.
G – Belt, 5:00 – Leatherman Wingman. Much lighter/thinner than a Wave, particularly since it clips on directly instead of needing a sheath. Not as well made, and the screwdrivers are way worse, but the smaller/lighter/cheaper (I’ve lost/destroyed two Wingmen in the last couple years) makes up for it.
H – Right Cargo Pocket – A pair of non-isolating earbuds (safe for wearing while walking). The current pair are Sennheiser MX300s.
I – Left Cargo Pocket – ThruNite T10 Flashlight. 1xAA, three mode (Hi/Md/Lo) with NO stupid blinking modes. Detailed impression here.
J – Right Cargo Pocket – A couple of spare snagless hairbands.

The major changes are that I’ve downsized my multitool and consolidated my ubiquitous computing device. I’ve also stopped regularly ruining cheap belts and started wearing a 5.11 1.5-Inch TDU Belt, which is thus far impervious to damage or problematic wear.

The interesting bit is, as always, the custom part. The current version of my pen case is this thing:
Pencase2013

It’s getting a little bit worn, and shows some minor design issues, but has been riding around in my pocket doing its job for several years now. The primary issue with this one is that every layer of material has a seam along the bottom, which allows the pencil point to escape through the stitching. When eventually I get around to replacing it, I think I’ll make the lower piece out of a different material (thin split leather?) and wrap it so there is a fold at the bottom and stitches up the sides, the current mid-weight upholstery fabric is otherwise adequate (light, inexpensive, and non-abrasive). I never made a proper pattern, just mocked it in paper then cut fabric to match, so there will be some work in replicating.

This would feel totally ridiculous if it weren’t so entertaining to read these from other people.

Reader Refugees

I’m getting a kick out of reading the stories from the Google Reader competitors reacting to the shutdown announcement. Google’s dwindling number of users appears to be counted in millions, which is a great many for almost any other entity. Feedly and NewsBlur seem to be the dominant destinations for reader refugees.

Feedly reports 500,000 new subscribers in the 48 hours following the announcement, and ordering 10 times their current bandwidth allocation.

NewsBlur, which is a one-man-show, had all kinds of excitement – they blew up their host, their mail provider, and unusually positive interaction from PayPal.

I’m happy enough with TinyTinyRSS, but NewsBlur was distinctly a close second – Newsblur is attractive (in terms of design, model, and UI), open source (Under an MIT licence), and supports self-hosted instances, but is seriously complicated to set up, by the author’s own admission – I tried on a VM, and decided that for now ttrss is a better choice.

They both seem to be excited more than anything, which is consistent with the reaction I’ve been seeing with the TTRSS developer (also a small pet project) and community – the shakeup could well provide some nice selective pressure for the RSS ecosystem.

(Posting here because I’m done with putting up with google’s failings – Plus doesn’t handle multiple links well, and I have no desire to fight with it).

Google is Getting Awfully Evil

TLDR; I no longer consider google trustworthy, Tiny Tiny RSS is a suitable, self hosted, replacement for Reader.

Until this week, Google had managed to convince me their services were trustworthy – more trustworthy than self-hosting – which is quite a feat , since I don’t tend to do well with faith in any context. Killing reader after it drained the rest of the RSS aggregator market took care of that illusion. Kicking the ad blockers out of the play store (on the same day) after Android had become the dominant species, and it no longer mattered that ad blockers are required to make the mobile web experience tolerable, and intentionally breaking Jabber federation later in the week just underscore the point.

Adventures in 3D Printing

The MakerGear M2 3D printer the KAOS lab ordered arrived last week. I am thoroughly impressed with the machine and how little fussing has been required to get decent prints out of it.

I’ve been pushing annotated pictures of our adventures with the M2 to a G+ album, because the auto-upload from my phone is too good to give up, even if the G+ album manager sucks. Take a look to get a taste of our massive new distraction.

Shapeoko: Part 5

SH6-1
This was originally posted as Shapeoko: Part 6, because I apparently can’t count.

A while ago I ordered a 300W ER-11 DC spindle kit from China to install in my Shapeoko. I finally got to the post office yesterday (stupid recipient-must-be-present shipping) to pick it up, am impressed with the whole process. Most of this post is about the spindle, there is some more belt tensioner tinkering down at the bottom.

Favorite Talks of 29C3

I’ve been watching the talks out of 29c3 as they become available online for the last couple days, and these are my favorites with comments. I’ve never come up with an excuse to actually go, but always find that it is the conference with the most things I am excited about every year, and end up watching more recorded sessions than I could have attended had I been present. The ones I picked below were both topics I found interesting and good presentations – there were a couple I hoped would be good but had talks that made me just give up and read the paper that I won’t mention here.

Shapeoko: Part 4

I got some more time to work on my Shapeoko over the last few days, and now have mostly correct 3-axis motion. As before, details under the fold.

Shapeoko: Part 3

Naturally, this post is a follow-on to Shapeoko: Part 1 and Shapeoko: Part 2. I’ve basically put the machine together now, and can move the X and Z axis around from the host computer, but still have to figure out belt attachments for the Y axis, and run the wiring in a sane way. I was holding up a microswitch to the various relevant spots for end-stops as I went, and everything but detecting the upper extreme of the Z axis should be easy. As in the last two posts, there is an assembly gallery under the fold.

Shapeoko: Part 2

This continues from where I left off in my previous post Shapeoko: Part 1.

I alternated my Sunday afternoon/evening between tackling my grading backlog and building pieces of the Shapeoko. This pattern works well for tapping since they are both exceptionally tedious tasks, but in different ways. Gallery with captions below the fold:

Shapeoko: Part 1

My Shapeoko kit arrived from Inventables while I was away at SC.

I’ve been trying to build myself a small CNC milling machine since 2009, and contemplating it for longer than that. It became clear that my original design, however educational, was a dead end sometime last year. I’d been idly watching the Shapeoko project for some time as it had similar aspirations to my design, and a couple months ago I was in a particularly mechanical mood when I saw that a batch had reached enough buyers to be produced, so I bought in for a mechanical kit to mount my existing electronics on.

The Shapeoko community is really excellent, and the kit was designed to be flexible, so I’m starting off with some suggested modifications – I’m using NEMA23 motors instead of the usual NEMA17 on the X and Y axis, because I already had some nice Lin Engineering 130 oz-in NEMA23 motors and the frame can fit them. I’m configuring for dual Y motors, which give more even force across the Y axis, and routing my belts on the outside of the frame, since I needed to buy different hardware for the NEMA23 motors anyway and this particular modification is widely recommended.

There is a gallery to document my first round of assembly below the fold (captions don’t display properly in the RSS feed).
