By on September 24th, 2015 in government, Jen, prepping

07:25 – I have a bone to pick with the US federal government. Why are they wasting the time of SEAL Team Six, Delta Force, and so on by sending them out to track down and kill minor annoyances like Osama bin Laden, when they could instead be sending them out to track down and kill phone and email spammers? I’m completely serious here. I get a dozen or more spam phone calls and thousands of spam emails every day, and I’m sure I’m not alone. (Yes, our phone number is on the DNC list; makes no difference as far as I can tell. What we need is a C/EMAD Call/Email Me And Die list.) We should be relentlessly hunting down and killing telemarketers and email spammers, wherever in the world they may be. And it’s a self-limiting problem. We’d probably have to blow away only 10,000 or 100,000 of them before the rest got the message. What do you call 10,000 dead phone/email spammers? A good start.

Email from Jen. She and her husband are considering improving their alternative electric power situation. They currently have a generator and a limited supply of fuel as well as a 14W portable solar charger. The former is fine until the fuel runs out, and latter is fine if all you need to do is keep a few AA and AAA cells charged. They’re thinking about a low-end off-grid solar installation. They don’t expect to run their AC or even their freezer or furnace, but they would like a bit more solar capacity.

Jen mentioned that they were thinking about buying and installing a Renogy 400W off grid kit and had a lot of questions about whether to go with the MPPT or PWM charge controller, what other items they’d need to buy, how much actual electric power they could expect a small system like this to produce, and so on.

I told her that I’m not an expert on solar power, but I’d be inclined to go with the MPPT charge controller. If they’re concerned about EMP or a solar flare they can stick everything in a Faraday cage and perhaps buy a spare PWM charge controller. Those cost only $35 or so. Under ideal conditions, which conditions never are in the real world, they could expect those four 100W panels to produce maybe 2 kW-hours per day. Real world, I wouldn’t count on much more than 1 to 1.25 KW-hour per day, or about as much as their generator will produce in ten minutes. Still, that’s roughly 25 times as much as their little 14W portable panel produces, and enough to keep all of their rechargeable cells and small devices charged.

They would also need several deep-cycle batteries (like golf-cart batteries), along with the cables to connect their solar charging system to their battery bank and a decent inverter to output 120VAC, ideally a true sine-wave model. A 35 amp-hour 12V deep-cycle battery runs about $75, so they could expect to spend $300+ on those batteries. In a pinch, I told Jen they could recharge standard 12V automobile batteries, although their plates are designed for very high current draws for short periods of time (running a car starter motor) rather than low current draw for long periods, and using car batteries to substitute for deep-cycle batteries would greatly reduce their useful lifetimes. The price of an inverter is determined by its output waveform–square-wave inverters are cheaper than sawtooth or modified sine-wave inverters, which in turn are cheaper than true sine-wave inverters–and its peak/sustained amp rating.

Although I didn’t suggest doing so, I told Jen that they could also get by with buying only the panels themselves and some batteries, doing without both the charge controller and the inverter. These panels output about 18V under ideal conditions, which means they actually output considerably less voltage under real world conditions. They could hook up panels in parallel to provide that same less-than-18V output and run it directly to their battery bank to charge the batteries. They’d have to keep a close eye on things to avoid over-charging or self-discharging but it could be done, although I’d recommend spending the $35 on a basic charge controller. Either way, they could keep a significant amount of energy stored in their battery bank, which they could use with a battery charger intended to operate on normal 12V vehicle power. They’d be able to keep a boatload of 1.2V NiMH cells charged, as well as small portable electronics like emergency lighting, radios, tablets, or notebooks.

By on September 23rd, 2015 in prepping

09:08 – Welcome to autumn. It looks and feels like autumn around here. Highs in the 70’s, lows in the 50’s, and rain. Barbara is now down to five work days left, and counting.

While she was out running errands the other day, Barbara stopped at the RV place to fill the new 20-pound propane cannister we’d bought at Costco. When she returned, I looked at the receipt and was puzzled. It showed “10 @ $0.99 = $9.90”. Ten what? Surely they didn’t put only 10 pounds into the 20 pound tank, but a 20-pound tank won’t hold 10 gallons, and even if it could I couldn’t imagine that propane was selling for $0.99 per gallon.

So I called them to find out. As it turns out, they indeed sell propane for $0.99/gallon, but they have a 10-gallon minimum, or about 42 pounds. As the guy said, it would have cost the same to fill a 30-pound cannister or a 40-pound cannister. If you’re actually using the propane routinely, it’d make sense to buy a 40-pound cannister. Those cost about $80 empty, versus $25 empty for the 20-pound cannisters. With one $10 fill, you’d be paying $70 for 40 pounds in two 20-gallon cannisters versus about $90 for one 40-pound cannister, but you’d break even after three fills and then you’d be paying $1/gallon to fill the larger tank versus $2/gallon to fill the smaller ones. We don’t use that much propane, just running our gas barbecue grill occasionally, so for stockpiling it makes sense for us to use the 20-pound cannisters. You can run a Coleman propane camp stove for a long, long time on one 20-pound cannister. We keep two full 20-pound cannisters plus a third one that’s in use, so we average about 50 pounds of propane available at any given time.

With a heat content of 20,000+ BTU/pound, that means we have about a million BTUs in those cannisters, enough to run a 10,000 BTU/hr camp stove burner for about 100 hours, or three hours a day for a month. Another way to look at it is how much water we could boil. Heating water from 62F to 212F requires 150 BTU/lb. Water weighs about 8.34 pounds/gallon, so it takes about 1,250 BTUs to increase the temperature of a gallon of water by 150F, so ignoring losses we normally have enough propane on hand to boil about 800 gallons of water or the equivalent.

By on September 22nd, 2015 in personal, relocation

08:03 – Today is the last full day of summer, with the autumnal equinox at 0421 ET tomorrow. Barbara is now down to six work days left at the law firm, and counting.

A vocal group of fringe Christian and Mormon religious nutters is claiming that the End of Days is scheduled yet again for the 28th of this month, so you might want to mark your calendar accordingly and make plans for the 29th and ff.

I called Amy Spell of Peak Mountain Properties, the real estate agency we’ve been using in West Jefferson, yesterday to get her recommendation for an agency in Sparta/Alleghany County. I’d have been happy to stay with Peak Mountain, but they don’t cover Alleghany. She recommended Mountain Dreams Realty in Sparta, so I’ll give them a call today and see if I can get something set up.

I’d have said “wrong with progressivism”, but this guy has a point. The Actors on ‘Fear the Walking Dead’ Exemplify Everything That’s Wrong With Liberalism

Nonsense like “microaggressions,” “nonjudgmentalism,” and “fairness” can only exist in a world built and defended by macroaggressive, judgmental, and unfair people who carry guns and don’t hesitate to use them.

By on September 21st, 2015 in personal, relocation

08:07 – As of today, Barbara has only seven work days left at the law firm. As of 1 October, she’ll be working for our own company, which we’re both looking forward to.

A couple of people have mentioned that a married couple working together at home introduces stress, but I don’t see that being any problem at all. We’re both very hard workers who focus on what needs to be done, and I’m certainly not prone too micro-managing. She’s a self-starter, and she’s already familiar with a lot of what needs to be done. I expect things will work out fine, without any stress.

We’ve decided to expand our relocation search to the counties that border Ashe County. Barbara wanted to look at Mitchell County, but a quick scan of homes for sale up there makes it pretty clear that there’s not a whole lot available. Not surprising, considering that the county seat has a population of 464. We want to relocate to a small town, but that may be a bit too small. One of the first places we considered was Sparta, NC. It’s the county seat of Alleghany County, and has a population of 1,770. A quick check on the Internet shows that there are quite a few suitable homes for sale there, so we’ll probably check it out in more detail. The last/first time we went up, we just walked around town and picked up a few brochures. This week, I’ll call a real estate agency up there and tell them what we’re interested in buying. We’ll schedule another trip up there for sometime after next week. It’s 60 to 70 miles from our current house, depending on route, and about a 1.25 to 1.5 hour drive.

We’re not in a hurry. We want to get away from Winston-Salem and its large underclass population, but wherever we move is where we’re going to stay, so we need to take as much time as necessary to get it right.


15:15 – Well, this is good news. The real show-stopper for any house we’d consider even looking at is lack of decent Internet service. The Romans had a phrase for it, “sine qua non“, or “without which, nothing”.

The one time we went up to Sparta, casual inquiries led us to believe that Internet service there was spotty and slow. The people we talked to mentioned DSL. Accordingly, we downgraded that area. One of the major reasons we preferred Jefferson and Ashe County was that most of the county has fiber Internet service. As it turns out, so does most of Alleghany County, where Sparta is. I talked to Skybest Communications, and from what the lady told me it sounds like Alleghany/Sparta is in pretty much the same situation as Ashe/Jefferson: the counties got a government grant to install fiber Internet services for an “underserved” area. There are a couple small parts of Alleghany that don’t yet have fiber service, but those areas have 12 Mbit/s down copper service, which would suffice for our needs. So, with the big potential roadblock out of the way, we can start looking seriously at the Sparta area.

By on September 20th, 2015 in personal, science kits

09:41 – The rate of kit orders is starting to slow, as expected in late September. The last half of September and all of October is generally pretty slow, with orders starting to pick up again in mid-November and running high through about the end of January. Then things slow down again until they start picking up in June and July.

Barbara is doing her regular house cleaning, bill paying, and so on this morning. This afternoon we’ll build some more biology kits and do other science kit stuff.

Barbara’s last day at work is a week from Wednesday. She plans to take a vacation day Friday, so she has only seven work days left. She wants to jump right into working her new job, so she starts full time for our company on Thursday, October 1. She’ll have things much better organized in no time, allowing me to focus on growing the business.

We’re getting to the autumn “in-between” part of the year, when to maintain an even temperature we’d need to run the air conditioning and the heating in the same day. In hot months, we usually keep the thermostat set at 75F (24C), and in cold months at 68F (20C). That means Barbara is always too warm during cooling season, and I’m always too cold during heating season. So she wears shorts and short/no-sleeve shirts during cooling season, and I wear flannel shirts during heating season. It works out fine most of the time, but during in-between times, both of us can be both too warm and too cold all in the same day.

And then there’s humidity. A few minutes ago, I had Barbara turn down the thermostat, even though it was only 72F in here. The problem is, the relative humidity was at 64%, so even I was warm. We turned it down to 70F to at least let the AC run for a while and remove some of the humidity.

By on September 19th, 2015 in science kits

09:39 – We’re both working on science kits today. First up is to build more chemistry kits. Our limiting item on those is the regulated chemical bags, so we’ll be able to build only 13. Still, that’s 13 that we don’t have now, and we’re down to only two in stock.

Amazon’s customer service is pretty amazing. I had Barbara filling chemical bottles yesterday, and one of the ones she filled was with a chemical I’d ordered from Amazon. I got two one-pound containers from them, which were marked as containing 454 grams each. The first one I picked up felt light, so I tared a balance and emptied the contents of the container into a large weigh boat. Sure enough, there was only 427 grams in that container. The second contained only 423 grams, so there was a total of 850 grams in the two containers, rather than the 908 grams I’d paid for.

The stuff cost about $31/pound, so I went to Amazon.com to post feedback to the seller. I’d ordered two items on that order, one of which was from a third-party seller and the problem one from Amazon.com. The only feedback option was for the item from the third-party seller, so I backed up and started looking for another option to let Amazon know that the products were light. The only option that made any sense was the one for return/refund, so I clicked on that. The item from the third-party seller was grayed out and marked non-returnable, so I clicked the radio button next to the product that Amazon had sold to me. I then had to choose whether both of the containers were a problem or just one, so I marked the option for both. On the next page, the only option was to request a refund, so I clicked on that, expecting to be able to enter a requested refund amount. I’d intended to ask for $5 or so, but it informed me that the product was not returnable and that Amazon had issued a refund in full for $62. I was flabbergasted, as was Barbara when I told her.

She said that wasn’t fair to Amazon and that I should contact them immediately to tell them what had happened. So I went back on their site and clicked on the “call me” button. Literally half a second later, my phone rang and I was speaking with a customer service representative. I told him what had happened and that I was expecting a refund for maybe $5, but certainly not $62. He thanked me for calling, and said that in that situation most of their customers would have just kept the money and not bothered to call them. I told him that that struck me as being just as dishonest as someone who was given too much change by a cashier and didn’t tell her. It comes out of her pocket, after all, just as this was coming out of Amazon’s pocket. But the support rep told me that it would actually be more trouble than it was worth to partially reverse the instant refund they’d issued to my credit card, and said just to keep the extra money.

By on September 18th, 2015 in science kits, weekly prepping

09:49 – Barbara is taking a vacation day today and heading out to run errands. We’ll spend the weekend doing science kit stuff. We’re low stock on just about everything.

Speaking of low stock, apparently there’s some kind of significance about this month for many Mormons. Some book or other written by a Mormon woman but not endorsed by the LDS Church is predicting a catastrophe this month, and I’m sure the severe flooding in Utah is reinforcing those fears. The result is that long-term food storage vendors are seeing a gigantic flood of orders. Augason, Thrive, and others are unable to keep products in stock, both on-line and in stores. Even Walmart.com is back-ordered on many of their shelf-stable food items because of the panic buying.

We’ve been covered up working on science kit stuff, but I did manage to get a few items that might be useful in the future. Here’s what I did to prep this week:

  • I read Lights Out by David Crawford, which is a different kind of PA novel. It focuses on a typical exurban neighborhood dealing with the effects of a continent-wide long-term power outage. The protagonist isn’t Rambo, which is a refreshing change. It’s a decent book, not great but a lot better than most of its genre. And it does give one something to think about.
  • I started design on a new kit. This one isn’t a science kit per se. It’s an heirloom seed kit, and I’ll sell it on-line via the prepping book. I’m not happy with any of the current heirloom seed kits out there, many of which appear to have an almost random selection of seeds, chosen without consideration for factors like reliability, ease of growing, nutritional value, climate adaptability, suitability for both northern and southern latitude day lengths, and so on.

The other problem with these seed kits is that they simply don’t include enough seeds. Ideally, of course, every prepper would already be keeping a garden, but the reality is that many preppers store heirloom seeds “just in case”. One kit I looked at included only one ounce (28.4 g) of bean seeds, which is 70 or so seeds. Yeah, under ideal conditions and assuming everything goes perfectly, those 70 bean seeds could produce a lot of beans. But what if conditions aren’t ideal or things don’t go perfectly? What if they’ve been in storage for so long that the germination rate is only 40%? What if animals or insects wipe out most of your crop? That’s why my kit will include 300 g of bean seeds, or roughly 750 seeds.

Then there’s the choice of plants. Nearly all of the seed kits include lettuce. Lettuce! It takes up precious space, requires a lot of work, and provides almost no nutrition. What’s the point to trying to grow it at all? Conversely, very few of the kits include turnip seeds. Turnips produce a massive amount of food and have high nutritional value. Anyone considering planting lettuce would do well to plant turnips instead. Or beets.

All of the kits include onions, which is fine. Onions are important for flavoring bulk staples. The problem is, many of the kits include long-day onion seeds. Long-day onions are fine if your latitude is about 45 degrees or higher. But at lower latitudes, the days never get long enough for those onions to flourish.

Almost none of the seed kits I looked at include even a basic selection of herbs, which are essential if you’re trying to cook appetizing meals from bulk staples. An herb garden doesn’t require much space, and I consider it mandatory to have the seeds necessary to keep a reasonably comprehensive herb garden, so those will be included in our kit. Another essential that these kits all leave out is tobacco seeds. Tobacco can be grown successfully up to about 55 degrees latitude if one has the proper seeds, and tobacco is an extremely desirable crop, if only for trade.

The other thing that worries me about many of these kits is how the seeds were processed and stored. Doing it right involves a lot of work, and my guess is that very few of these companies have bothered to do that work. If the seeds are dried properly (to ~7% or 8% moisture content but not much lower, which would “harden” the seeds and reduce germination rates) and frozen, they should remain viable for a long time. That’s how the international seed banks do it, and that’s why their vaults are located in arctic climes. I also noticed that most of these seed kits advertise that they’re packed with an oxygen absorber, which tells me that these companies don’t know what they’re doing. Using an oxygen absorber buys you nothing and may actually shorten the shelf life of the seeds.

I’ve done some germination testing of the Lima bean and carrot seeds that we include in biology kits. After five years stored just in PE bottles with no special dehydration or other treatment, I got germination rates of 50% to 60% (versus 85% to 90%+ on fresh seed). Germination rates of seeds also depend heavily on species, but I feel comfortable saying the seed kits we produce will yield reasonable germination rates after at least three to five years stored at room temperature and considerably longer if kept frozen. If nothing else, we can include a lot of seeds for species that tend to lose viability quickly over time. It doesn’t matter if the germination rate is only 10% if you have ten times as many seeds as you intend to plant.

So, what precisely did you do to prepare this week? Tell me about it in the comments.

By on September 17th, 2015 in Barbara, business, personal, politics

08:21 – I’m losing track of days. Barbara pointed out last night that she’s taking a vacation day tomorrow, not today. For some reason, I was thinking that yesterday was Thursday. At any rate, she’s off tomorrow.

The way things seem to be trending, the American people are making it pretty clear that the last thing they want as president is a politician. On the Republican side, the leaders are: Trump, a demagogue but not a politician; Fiorina, a businesswoman who destroyed Hewlett-Packard, but not a politician; and Carson, a non-entity, but not a politician. On the Democrat side, we have a small group of elderly political hacks, but no non-politicians. Sounds to me like the Democrats are badly in need of a non-politician.

The FedEx guy sneaked up on Colin yesterday, even though the main front door was open and Colin had an unobstructed view of the street through the glass storm door. FedEx delivered one box from walmart.com that contained the five boxes of dog treats that I’d ordered. When I checked the walmart.com site, it claimed my entire order had been delivered, but none of the bottles of Bertolli pasta sauce were in the box. When I checked the FedEx tracking number, it told me that everything had been delivered, but below that line it said that a shipment had been damaged and was being returned to sender. This is the second time this has happened on a Walmart order that contained items in glass.


11:21 – September 30th is Barbara’s last day of work at the law firm. On Thursday, October 1st, she comes to work for our company, The Home Scientist, LLC.

I need to get ready for that so that she can hit the ground running. Actually, I’ll probably give her the rest of that week off so that she can enjoy some free time, unless she just wants to start work immediately. Of course, one of our corporate benefits is that any employee can take as many paid vacation days as he or she wants to.

The first week or two we’ll focus on Barbara learning the business. Eventually, I want her to be able to do everything other than design new kits and write manuals. She doesn’t have any lab experience, so I’ll continue doing stuff like making up chemicals myself, but I will have her at least watching me to get some idea of how it’s done.

I intend to transfer all the administrative to her, including inventory, ordering and receiving, and so on. She’s much more organized and detail-oriented than I am, which isn’t surprising considering that she’s a librarian. I think this will all work out very well. The problem may be in her handling of mistakes. I expect mistakes. They’re just something that has to be dealt with. But Barbara REALLY hates making mistakes, so I’ll have to get her past that. We simply have too much to deal with to expect perfection.

08:56 – This is the time of year when I’m interrupt-driven. Someone orders a full forensic science kit, FK01A+B+C, and I’m down to just one of the FK01C kits in stock. Better build more. I could go a week or a month before I get another FK01C order, but someone could order ten of them tomorrow. My inventory records show I have enough of the components in stock to build 18 more, so I head downstairs to build those 18. It turns out I have 18 of everything I need except Modified Griess Reagent Part A, of which I actually have only 4. No idea where the other 14 went. So I make up a liter of Modified Griess Reagent Part A, which is enough to fill 33 bottles. Fill those, print out 33 labels, and label the bottles. Back to the assembly table, where I make up and bag the 18 FK01C kits. And now I’m down to zero stock on everything I need to build more FK01C kits than the 18 I now have on hand. On to the next thing we’re short on.

Until a week or so ago, I thought we were in decent shape on the CK01B chemistry kits. Those normally sell in pretty small numbers. The larger and more expensive CK01A chemistry kits usually outsell the CK01B kits by about 10 to 1. But we’ve had a flood of orders for CK01B kits, including three this morning. So I guess I’d better put together another dozen or two CK01B chemical bags. Oh, wait. I just found a bin full of those downstairs. Turns out I built those bags Monday and had completely forgotten doing so. It’s no wonder that my inventory gets completely screwed up this time of year. When I’m building batches of 30 of one type, it’s easy to keep the inventory updated. When I’m interrupt-driven, stuff falls through the cracks and comes back to bite me later.


10:53 – Sometimes, for whatever reason, one leaves oneself unprepared for something that’s important, in which case one just does the best one can and hopes for the best.

By this time, we’d hoped to be at least preparing to move up to the mountains, but it hasn’t worked out that way. With colder weather on the horizon, I’m concerned about heat. If we have a power failure, we can heat the house with our natural gas logs and our natural gas water heater will continue to work. Natural gas is the least likely utility to fail, so I’m not overly concerned, but it’s still at the back of my mind.

If the natural gas did fail for some reason, we could use the wood-burning fireplace downstairs. The problem with that is we have very little firewood. If we were up in the mountains, I’d have ordered a couple or three cords delivered, but for obvious reasons I don’t want to do that while we’re still in Winston-Salem.

Our next fallback is the catalytic propane heater, which is safe to run indoors and will suffice to keep one room at a livable temperature. Counting the 20-pound propane cannisters, we have enough propane to keep that heater running for a couple weeks. Barbara is taking a vacation day tomorrow to run errands, and one of her stops is to fill a new 20-pound propane cannister we bought at Costco. If we did suffer a natural gas outage, the first thing we’d do once it became obvious that the problem was severe is drive over to the Walgreen’s a mile or so from here and load up on Blue Rhino propane cannisters while there were still some to be had.

09:14 – I sent in the state and federal estimated taxes yesterday. Grrrrr.

Barbara suggested last evening that given the several burglaries we’ve had in the neighborhood, I should start locking the front main door when I walk Colin. Colin and I just spend 10 or 15 minutes each time going up and down the block, so we’re never out of sight of the house and always within 175 yards of the front door. Colin can cover that distance in under 10 seconds, and the sight of a 70-pound dog charging flat out would certainly disconcert most intruders. Even so, I think she’s right, so I’m now locking the door each time we’re away. I don’t feel at all threatened in our neighborhood, but it is better to be safe.

She said it’d only be for a couple of weeks, because after her last day of work she’ll be at home most days. I disagree. If I leave the house and she’s here alone, I want her to lock me out. At least the glass storm door should be locked at all times. Otherwise, she could walk out of the bedroom or her office and find an intruder in the house with no warning.

I’m building and shipping science kits, as usual.


10:58 – Big surprise. Hungary is discovering that those hordes of muslim invaders are cutting through their razor-wire fence. I have zero military experience, and I could have told them that a fence is useless unless it’s defended. Hungary needs to set up machine-gun emplacements about every 300 to 400 meters and order those manning the emplacements to open fire without warning on anyone who tries to come over, under, or through the fence. It would also help to build a second fence about 100 meters inside Hungarian territory and sow the dead zone between the fences with a lot of land mines. Of course, that’s also what the US should be doing on our border with Mexico, and we haven’t done it either.


14:43 – Here’s irony:
