Adding ADS-B IN

I really wanted to add ADS-B to the RV-12, for some pretty obvious reasons.  Getting weather and traffic data for improved situational awareness seems like a really good idea.  I’m also not thrilled with the tiny buttons and small screen of the Garmin 496 currently mounted in the panel.  So, I started looking at various alternatives for ADS-B IN.  I figured I had several choices…

  1. Do nothing.  No weather, no traffic, no expense.  Punch flight plans into the Garmin 496 by hand, let that drive the autopilot.  It’s not the worst fate, but there are better ideas.  Cost: None.  Benefit: None.
  2. Pay a ridiculous amount monthly for XM WX, still get no traffic.  No freakin’ way.  Cost: High (several hundred per year).  Benefit: Very low.
  3. Replace the Garmin 496 with a 696 and GDL-39.  I was almost there.  I bought and repaired a used 696 and it’s very nice.  The GDL-39 is not cheap, but I’d have traffic and WX.  Flight planning is easier, but the maps need updating ($$).  Plus it would take MAJOR surgery on the panel — like rip everything out, rearrange it all and rebuild the entire panel with everything custom.  Cost: Mid-high, even after selling the 496 (it’s a little scuffed and gouged on the edges).  Benefit: Mid-high.
  4. Foreflight running on an iPad Mini, with Stratux.  It’s almost a perfect solution…  but it won’t drive the autopilot, which means I’d have to enter the flight plan twice (once in FF, once on the 496) and any enroute changes would need to be done in two places to keep the AP on course.  Foreflight would require an annual expense, though it’s not too bad.  And of course iPad Minis are not cheap.  Cost: High.  Benefit: High.
  5. Avare running on a Galaxy Tab S2 8″, with Stratux.  Avare is completely free including charts, maps, approach plated, A/FD, all of it.  It’s not QUITE as nice or as smooth as ForeFlight, but fairly close.  And it will drive the autopilot with a bluetooth-serial converter, which FF cannot do.  I can keep the 496 in the panel as a backup just in case.  Cost: Medium.  Benefit: High.

I seriously considered 3 through 5.  If I’d been able to figure out how to reduce the amount of panel rework for the 696, or if the cost of the GDL39 wasn’t so high ($400+ used) I’d have probably done that.  As it is, I picked up a used 696 cheap, repaired the battery connector, and will sell it — probably for enough profit to pay for the Galaxy Tab.  That would make my total ADS-B/EFB setup cost under $200, even after mounting good antennas on the plane.

Sorry, I don’t read Chinese…

For the past several weeks I’ve been getting a fairly large amount of Chinese language spam leaking through. Since nearly all of the data (From:, subject, etc) are Chinese characters, my regular Postfix spam filters have not been effective in eliminating it. I finally got tired enough of it to do a little Googling. It’s trivially simple to just reject any incoming email with Chinese characters in the subject line:


/^Subject:.*=\?GB2312\?/ REJECT Sorry, this looks like SPAM (C1).
/^Subject:.*=\?GBK\?/ REJECT Sorry, this looks like SPAM (C2).
/^Subject:.*=\?GB18030\?/ REJECT Sorry, this looks like SPAM (C3).
/^Subject:.*=\?utf-8\?B\?[456]/ REJECT Sorry, this looks like SPAM (C4).

I made the change last night, and this morning came in to find no Chinese spam and several rejects in the mail log… all from pretty obvious spam sources, like this one:

Jul 6 01:12:51 newman postfix/cleanup[30385]: 99EB31A6D3: reject: header Subject: =?utf-8?B?44CQ5Lqk6YCa6ZO26KGM5L+h55So5Y2h5Lit5b+D44CR5bCK6LS155qEZGFpbmlz?=??=?utf-8?B?6I635b6XMTAw5YWD57qi5YyF5aSn56S85rS75Yqo6LWE5qC877yM6aKG5Yiw5bCx5piv6LWa?=??=?utf-8?B?5Yiw?= from spamtitan2.hadara.ps[217.66.226.109]; from=<wkh@p-i-s.com> to=<dale@botkin.org> proto=ESMTP helo=<spamtitan2.hadara.ps>: 5.7.1 Sorry, this looks like SPAM (C4).

How much is your time worth?

Lord, I hear this question so often as justification for an overpriced widget or service.  Apparently some people think one should spend any amount of money to avoid doing a few hours’ worth of work.

The latest example is a neat little box for use on experimental aircraft.  It replaces the traditional master battery and starter contactors, as well as a current measuring shunt and maybe a fuse or two.  I think there may even be a diode or two thrown in for good measure.  It would simplify the wiring on the firewall side of an experimental plane, sure.  It might even shave one or two nights off of your build time.  Maybe.  You’ll still need to do some wiring, and of course there’s a nice canon plug on the back side, so you’ll still need a crimp tool and it’ll need to be connected to various switches and stuff on the panel.  All in all, I’d say it would be a nice little $200-$300 box.

The problem is, they’re apparently going to want about $1200 for  it.  Say what?  that’s about $1050 or $1100 more than I’d spend on the parts to do the job the old fashioned way.  On one of the very few online forums I use any more, there is a little bit of discussion about it.  And just as sure as Godwin’s Law it’s only a matter of time before someone chimes in with, “How much is your time worth?” – as if that justifies any expenditure, no matter how ridiculous.

Well, I’ll tell you.  For one thing, my “internal billing rate” — how much time I’m willing to expend to avoid an expense, or conversely how much money I’m willing to spend to avoid work — varies greatly with how much I enjoy or do not enjoy the work to be avoided.  Self-surgery?  Yeah, sure, I’ll pay a professional to avoid doing that work.  Mowing the lawn?  It better be cheap, I’m not shelling out $40 a pop for that.  Wiring work on an airplane I’m building?  Well, let’s just say $1200 will buy an awful lot of hours.  I figure it will probably take about 2 evenings of work — let’s be really generous and call it six hours — to do that wiring, of which maybe half would be saved using the new whiz-bang box.  So that works out to – oh, let’s see, carry the one…  roughly $350 an hour, and if the bloody thing ever breaks I have a plane out of commission for God only knows how long, versus a trip to Auto Zone for parts.  I don’t know how long they will be manufacturing and supporting these, but I’ll bet my airplane is flying for longer than that…  meaning that some day this thing is almost certainly going to cause a time consuming and expensive problem.  Hmm, there goes all that time we “saved” on the front end.

I’m sure they’ll get some customers, but I’m afraid I won’t be one of them.  And I won’t even feel like a tightwad.

Why I fear for Western civilization

I really wish I could just drop our cable T V service altogether.  I am beginning to think that just having the cable signal inside the house is lowering our IQ.

With crap like The Bachelor and the rest of the voyeuristic garbage on network TV, and the horde of brainless bullshit on the cable networks…  what have we become?  A nation in which Honey Boo Boo (and her circus sideshow of a family) can become cultural icons scares the hell out of me.  We’ve got pageants where toddlers and young girls are made up like street hookers and paraded in front of the crowd.  We can’t forget Dance Moms and now its growing horde of imitators.  And the phalanx of wedding dress micro-dramas.  And I see now Kate is back, minus spouse, but having picked up a few aides-de-camp along the way.  I can think of no more certain way to remain a single mom than to demonstrate on TV just how much of a train wreck you are.  So-called “Gypsy” clans, and the most ridiculous attempts at exploiting Amish culture that I can imagine – oh, to be Amish and have no electricity!  Then you wouldn’t ever see the fake “survival” shows, the fake “moonshine” shows, and the fake everything else shows.  I could go on and on and on. 

Honestly…  if I were of dating age and raised with a TV in the house I’d probably enter a monastery.  :shudder:  The fact that such shows find enough viewers to make them financially viable makes me question our collective futures.

Why am I such a tightwad?

Yesterday in the mail I got a really nice invitation to contribute to an organization whose goals I support.  They even sent me a nice little pocket sized copy of the Declaration of Independence and the US Constitution.  And these guys are good; I really do like the work they do.  And I won’t send them any money.

Why?  Because it means that they will immediately add me to their list of people to harass constantly and incessantly for more, more, more.  I have had this happen with any organization to whom I give a dime.  I donated a couple of times to the Wounded Warrior Project, with a letter asking them very plainly to not waste their money (the money I donated, in other words) sending me crap in the mail begging for more.  I know who you are, I told them; I know where to find you and if I decide to donate more, I will do so without their prompting.  Furthermore, I told them, if they did decide to waste the money I donated on mailers and phone solicitations to try and get more from me, I would cut them off.

Unfortunately, since then they have wasted much of the money I donated on mailing me crap every week or two begging for more.  Sorry, screw ’em.  Not another penny, since they seem to be more focused on soliciting money than anything else.  I won’t donate to organizations that will simply waste the money.

I told the NRA the same thing.  After I joined I was inundated with junk mail begging for donations.  I wrote them a nice letter telling them that if they continued wasting my dues on sending me junk mail, I wouldn’t renew.  The junk mail stopped, and I’ve been a member ever since.

Most of the solicitations I get, though, go unanswered.  It seems that too many organizations are no longer charitable or activist or whatever their nominal purpose is — they are focused on fundraising, apparently for the sake of fundraising.  If I could kick in a few bucks and be left in peace, maybe I would.  But I hate paying for more junk mail.  Sorry if that makes me a tightwad.

Small business shipping made easy

This may at some point begin to sound like a commercial, but it really isn’t.  I promise.  I receive nothing from anyone in return for writing this kind of stuff; I do it just to hopefully help out fellow small business owners.

I know (and know of) a lot of owners of small businesses who regularly ship packages all over the US and worldwide.  Most of them expend a lot of time and effort on shipping.  I suspect this level of hassle is the norm for small businesses; I have talked to several large dealers and distributors who offer to be my exclusive distributor and relieve me of the crushing burden of shipping and order fulfillment.  The truth is, order fulfillment and shipping take up a very small amount of the total time I spend running my business.

I know people who pack up each order, write the recipient’s name and address on the package (or print a label), drive to the post office and stand in line to have packages weighed and postage added.  Ugh.  Incredible.  I used to do that too, but it was years ago.  And filling out Customs forms for overseas shipments?  Torture!  At one time I seriously considered just NOT accepting any orders from outside the USA – -including APO/FPO addresses.

Others use on line tools like USPS’ Click-n-Ship to prepare labels.  It’s a lot better, but the user interface is clunky, and you either spend time cutting and taping paper to packages, or pay through the nose for expensive labels.  I looked into it, I even used it a few times.  It’s only marginally better than the trip to the post office.

If you ship more than a few packages per week, you owe it to yourself to go with a postage supplier.  I use Endicia, a choice I made after looking at them, Stamps.com and one or two others.  Pitney Bowes was at the bottom of the list by a wide margin.  I don’t remember the specific disadvantages of Stamps.com, but Endicia was the best suited for my needs.  With any of these services, you pay for postage on line, print your labels with postage included, and drop your packages off or have them picked up.

So why Endicia instead of Click-n-Ship?  With Endicia, I get a slight discount on postage and free delivery confirmation/package tracking.  Their software is installed on my PC, and can communicate with a USB postal scale to automatically weight each package.  I don’t use one simply because I know what 90% or more of my packages weigh, but when I see a good enough deal on a scale I’m buying one.

I use 4×6″ thermal labels.  They’re available for very little money, since they’re produced in vast numbers for UPS, Fedex and others.  I buy cases of 400-label rolls.  They go into the used Zebra LP2844 printer I picked up for under a hundred bucks on eBay.  In its former life it was used in a UPS store, and it’s given me three years of trouble-free service so far.  The really nice part?  I can print ANY kind of postage.  First class parcel, Priority Mail, Express, and international — INCLUDING the Customs form.  It’s SO nice to never have to fill out that stupid non-printer-friendly green form again!  Some forms, like an Express International package, can’t be done on a 4×6″ label.  For those I have the regular printer and USPS-supplied stick-on document sleeves.  Endicia prints all the required forms with postage, ready to go.

For $15.95 per month I get the ability to print labels without the postage amount shown…  so I don’t have to explain over and over to customers why I charged them $2.50 for shipping when the postage was only $1.93 (boxes, labels, printer paper and ink for the packing slip, packing material and gasoline are not free). I can get a refund on labels I don’t use; I can print return labels when a customer needs to return something.  In short — my shipping is as close to effortless as it can be.  And the post office employees love it when I drop off a tub full of packages WITH a USPS scan form so they don’t have to scan each package, just the form that puts each one into the system for tracking and delivery confirmation.

If you’re still writing out shipping labels, or if heaven forbid you’ve got a postage meter, you really owe it to yourself to check out Endicia.  They’ll usually give you a free trial period, and you don’t need anything special to get started — you can use your existing printer and plain paper or a box of Avery labels form Office Depot while you try it out.  Then you can develop your own process and streamline your shipping to take up less of your time and energy.

Various stuff…

First of all, sue me…  I’m loving the iPhone.  I never thought I would.  There are a few little annoyances, but overall it’s a great little widget.

Went to the Ak ARC flea market Saturday.  I had a table to sell kits, but I don’t know why I bothered.  I did (just barely, maybe) cover my breakfast, the table and my gas to drive there and back, so I guess it was OK.  Honestly, I think most of the stuff for sale was the same crap I’d seen last year.  There was, however, a table set up by the Omaha Maker group, and separately a ham had a 3D printer running printing out something or other, I never did figure out what.  So why did I go?  It was good to see and talk to some of the hams I only see once in a while.  Jack WA0SAQ was there, Dave WJ0Z and some others I seem to only see once every year or five.

I did some CNC engraving on the end panels for a new flavor of PicoKeyer.  I think it turned out pretty well.  It will be a little extra work — OK, a lot of extra work, but I think it will be worth it.  This will also probably be the motivation I need to finally break down and make a better fixture for the end panels I use for the boxes.  Maybe something I don’t have to stand there and hold each one in place.  It would be a worth a lot to me to be able to not stand there the whole time the mill is running, holding parts and trying to avoid getting an end mill through a thumbnail.  McMaster, here comes an order!

And…  some days I miss not having something that looks like airplane parts in the garage.  In a couple of weeks, though, I should have a “canoe” going and by Spring it should be looking airplane-y again.

That is all.

Technical stupidity.

It baffles me how people let their stuff get so messed up, and how companies will go so far out of their way to NOT be there for customers.

I got a phishing scam email supposedly from First National, where we used to have accounts.  Being the nice guy that I am, I figured I’d let them know the specifics.  After all, some people are dumb enough to fall for stuff like this.  A fake “IRS agent” almost managed to convince my 88-year-old mother to wire a few thousand dollars to avoid going to jail — never mind that she doesn’t owe the IRS a penny, never has and has never tried to cheat on her taxes.

Well, of course the only way to contact FNBO or FNNI is via a web form.  So I spend several minutes sending detailed information to them — the target web link, the email header, etc.  Then I hit the “Submit” button…

And got an error message.

Screw ’em.

Into the dark side. Or whatever.

apple-logoMy Droid 3 has been giving me fits for a while.  The phone itself is fine…  there doesn’t seem to be a hardware problem.  A couple of months ago, though, it started nagging me daily to install a slew of app updates, including “Google Play Services”.  Half the apps I use regularly finally refused to run at all until I installed Google Play, which I resisted because it wanted access to everything on my phone.  All data, all history, location, email, everything.  I finally had no choice but to dump the phone or install the damn thing, so I installed it (and the subsequent dozen or so other app updates).  Since that time the phone has been plagued with odd behavior.  It will periodically freeze up, require reboots, not be able to place a call for several minutes after a restart, and I’ve had to pull the back off and remove the battery a couple of times when it froze up and started getting uncomfortably hot.

My employer offers me the option of having a corporate owned cell phone.  We’ve currently got a choice between Blackberry and iPhone.  I can understand their refusal to allow Android phones to connect to the corporate network — the ease with which an Android can be rooted and bent to the owner’s will is great for experimenters, developer and hackers (a term used in the proper, good sense here) – but it also removes any surety that an app can actually be trusted.  Anyway, the Blackberry phones are locked down tight and everything (web, email, etc) goes through the corporate proxies.  The iPhone situation is different; there’s a secure VPN app that handles all the corporate traffic, but outside of that app web browsing and email don’t pass through company servers.

I opted for the iPhone, so as of yesterday afternoon I have a shiny new iPhone 5S.  It is, I believe, the first Apple product I have ever owned, aside from a garage full of Lisas that passed through my hands back in the late 1990s. I have not used any Apple products for more than a few minutes since the Apple ][e.  No iPod, iPad, iPhone, Macs, iMacs, nuthin’ more than a passing familiarity.

So far I’m impressed.  The phone itself is a thing of beauty, which is to be expected of any new cell phone.  The Samsung Galaxy S III that Lisa carries (and the IV and V, I assume) are nice too.  So no big surprise there.  The thing is quite responsive, and almost everything is simple and intuitive.  I especially like being able to uninstall an app without having to wade through setup menus to do it, and the ability to effortlessly pull up the flashlight, timer, camera and calculator without even unlocking the phone — very nice.  It will even show me text messages and the first couple lines of new emails without unlocking the screen.

There are several areas in which iOS seems to really outshine Android OS.  The email client is a bit nicer than any I have used on the Droid.  iBooks has far and away the best PDF reader I have used on any platform.  The voicemail management is so well integrated with Verizon voicemail that I honestly didn’t realize it was there at first.  I see that there is a built-in flashlight app (lacking on the Droids) and timer/stopwatch.  The camera and its app is much better than anything I have seen on a phone before.  Overall, the UI seems a little smoother, a little quicker, a little more intuitive.  I can see why people rave about their iThingies.  And Siri works pretty well.  I even like the Lightning connector, though the cable they included could have stood to be about a foot longer — easily and cheaply remedied on Fleabay.  And while more of a hardware thing, the fingerprint scanning button is slick as all hell.

A few areas could use improvement.  For one, I do miss the “back” button.  I really do.  I get the whole single-button idea, but I’m constantly reaching for the back button.  A nightstand/dock mode like my Droid has would be awfully nice (maybe I just haven’t found it yet).  And for the love of all that’s good in the world, why can’t I just drag and drop files from my PC??  Using iTunes to copy PDFs to the phone is just plain stupid.

Anyway, the message here is really twofold.  First, kudos to Apple — the iPhone is really, really nice.  I don’t know that I would ever have bought one if I had to spend my own money on it, but it’s nice.  Second, shame on Google.  It took a lot to drive me away from Android, a platform I loved for what it was and what it represented.  They just couldn’t leave well enough alone.  They have managed to make it so intrusive and so inhospitable that even I had to walk away in disgust.

Now, about that Macbook Air…  hmmm.

Seoul Burger

If you like things a little spicy but not too wild, try this…

Your favorite burger patty — home made, or the nice 1/3 lb. Angus patties from Costco
Your favorite bun
Drop on a layer of medium-hot kimchi
Optional: Add a fried egg (which makes any burger better)

I’d post a picture, but mine was very short-lived.  🙂  Simply flippin’ awesome.  For those of us limiting red meat and fat intake due to clogged up arteries, you want to make the most of that rare burger experience.  Even if you’re not a big kimchi fan — and it can be something of an acquired taste — kimchi as a relish on hamburgers or hot dogs is amazingly good.
