08:03 – Barbara’s dad may go home from the hospital today. Barbara and her sister were surprised yesterday when the doctors said her dad might be released, but he is doing a lot better. Barbara and her sister laid down the law to the doctors, and told them that they’d take Dutch home if and only if he didn’t have any tubes remaining in him. This has been going on in one form or another since May, and they simply can’t deal any more with almost daily (or nightly) trips to the doctor or hospital for tests and treatments.

So we’re going to try to have an almost normal weekend. Unless there’s some kind of emergency, Barbara plans to spend the weekend at home doing regular stuff. I wanted her to take a couple of days off so she could just relax, but she insists she wants to work on kit stuff. So this morning I’ll do laundry and we’ll do final assembly on the current batch of 30 chemistry kits. Which is good, because with overnight orders our current inventory of chemistry kits stands at minus two. Once we complete final assembly on that batch and ship the outstanding orders today, we’ll get started assembling another new batch of 30 chemistry kits and building subassemblies for the first batch of 30 forensic science kits.

08:02 – Barbara’s sister called at midnight to say that she was on her way over to their parents’ house to meet the 911 responders. Their mom had called 911 because their dad was breathing strangely and their mom couldn’t wake him up. At around 12:45, Frances called back to say that Dutch was awake and responsive, but they were transporting him to the emergency room. Barbara quickly dressed and left to meet them at the hospital. She got back home about 6:45 and said they’d just admitted him, finally. He’s in no immediate danger, but for someone aged 90 this whole sequence of events over the last two or three weeks isn’t good. Barbara got almost no sleep overnight. She’s sleeping now, finally, with Colin curled up next to her on the bed.

For the last ten days or so, Dutch has been on outpatient IV vancomycin to treat a drug-resistant S. aureus infection, with Barbara and her sister administering the drug daily and taking Dutch in daily to be tested for serum vancomycin levels. Our main concern at this point is that his levels have remained elevated, which indicates that the vancomycin isn’t being eliminated, which in turn suggests that Dutch may be in renal failure. At the same time, they’re concerned about Dutch’s persistent edema and congestive heart failure. He’s now simultaneously water-logged and dehydrated. The dehydration causes confusion and unresponsiveness, but hydrating him would increase the edema. Conversely, they can’t treat him with lasix or another diuretic to reduce the edema because that would dehydrate him even further. Everyone, especially Dutch himself, is exhausted and under extreme stress.

09:48 – Barbara went to dinner with a friend yesterday, so I spent the evening watching Heartland reruns. Bizarrely, Netflix streaming has only the first 14 of 18 episodes in series three, so when I finished watching the final streaming episode I popped in the DVD to watch the remaining episodes.

The first menu that comes up when the DVD loads offers a choice between English and French, so just for the hell of it I chose French. I knew that Amber Marshall is an Anglophone, but I figured some of the other cast members might be bi-lingual, so I decided to see if the original actors had dubbed the French audio in their own voices. Nope. All of the voices I heard were done by other people.

But I did notice something strange. I don’t speak French, but I grew up in a neighborhood where many of the older people spoke Italian at home. That and my years of Latin often allow me to work out the general sense of what’s being said by a native French speaker and I’ve listened to quite a bit of spoken French. All I can say is that the French soundtrack didn’t sound French to me. It sounded like a severely degraded French overlaid with a strong accent. But whatever it was, it didn’t sound to me like French. I thought people in Quebec spoke French, but apparently not.


We’re now officially out of chemistry kits. We ran dry this morning, with three orders overnight that accounted for the only three finished chemistry kits remaining in stock. So today I’ll start final assembly on another 30 and move them to the finished-goods inventory area. Then tomorrow or Friday I’ll start building yet another 30, as well as ordering in some components we’re going to run short of.

I ended up spending most of yesterday completing a project that had been high-priority on my to-do list, but had slipped down out of sight. The forensic science book hits the bookstores one week from today. At the end of each group of lab sessions, there are review questions. I was supposed to have done an answer key document for those questions, but I didn’t get around to it until yesterday. So now it’s complete and ready to go.


14:31 – I just received the last item but two required for the forensic science kit. I actually ordered those missing items, along with one other item, on 1 August from imedmart.com. Don’t ever order from them. I got an email from them soon after I placed the order, confirming that I’d placed the order, but without saying what I’d ordered. The email said they’d send me another email with tracking information once the order had shipped. So I waited. And waited. And waited. Finally, on 9 August, I visited their web site again to check the status of my order. Of the three items I’d ordered, two had disappeared from my order as shown on their web site. The third item was listed as “processing” or something similar. So I called their “support” phone number.

At first, everything seemed normal. Rotten elevator music, and a recorded voice that popped up periodically to tell me that my order was important to them. Yeah, right. After the first five minutes or so on hold, the recorded voice changed. It now told me that I was second in line and could expect a four minute wait. A minute or so later, it came back to say I was second in line and could expect a six minute wait. Eh? Then a minute or so later it came back to tell me that I was now first in line and could expect a ten minute wait. Crap. At the ten minute mark, I got a different recording that told me their customer service reps (which I’m sure was an exaggeration; there can’t be more than one, if that) were extremely busy and that I should fill out a support request form on their site. It then hung up on me. I went to that page and filled out the form, which told me I could expect a response within 36 hours.

On Friday, I got an email from them telling me that my order had shipped. Again, no details about what exactly had shipped, nor any tracking number or other information. The order showed up yesterday. The only thing it was the one item they’d admitted that I ordered. So I called back and wasted another ten minutes trying to find out if they ever intended to ship the other two items or not. I finally left them a message on their customer “support” feedback form telling them I was going to order the other two items elsewhere, so please cancel them. And that if they did ship them to me, I’d dispute the charge on my credit card.

I still needed those two items, so I went off to Google in search of a reasonable price on them. I found one, which was about $90 not including shipping for those two items, versus $79 plus shipping from imedmart.com. The vendor is called Cooper’s Nutrition/Living Naturally, and it’s obviously a small family business. I entered the two items in my shopping cart, and clicked on the checkout button. Something happened to me that had never before happened in all of the hundreds of transactions I’ve done to purchase products on-line. The site thanked me for my order and displayed an invoice. It emailed me a copy of the invoice. No problem at all, except that it never asked me for my credit card number.

So I went to their customer support feedback page–one of those things with fields at the top for your name and email address–and left a message saying what had happened. A moment later, I got an email bounce from them quoting my feedback message and saying the email to them was undeliverable. So I tracked down a phone number for them–not easy, since they don’t publish it on the site–and called the place. The guy who answered laughed when I told him what had happened. He said they hadn’t gotten their site setup to take credit card information yet (they’ve been running since 1999), and that he’d have called me to get the credit card information over the phone. He said he’d call me back in a few minutes after he’d checked to see if the two items I’d ordered were in stock. Four or five hours later, I finally called him again. He said he’d been meaning to call me, but had been busy. Okay, I can understand that. He said both items were out-of-stock, but they’d have them in Thursday. He said they’d ship Priority Mail, which means I should get them maybe next Tuesday. That’s soon enough, but I’m glad I followed up.


15:46 – So, I decided to do a quick mini-batch of 6 chemistry kits, just to hold me for the next couple days, I hope. I packed all of the items needed in six shipping boxes. Except for the 100 mL graduated cylinders. I had none of those in inventory, at least not on the shelves. But I did have stacks and stacks of boxes sitting in the library, and among them I knew there was one that had 120 100 mL graduated cylinders in it. I even knew which vendor it was from and that it was in the group of four boxes that arrived from that vendor last week. That meant it was toward the front of the piles.

As long as I was opening boxes, I figured I might as well check the contents against the packing list. So I opened all four boxes–the graduated cylinders were in the last one, of course, and checked all the items in, getting dirty and sweaty in the process. Now, instead of four large boxes sitting in the library, I have bunches of small boxes: twenty dozen each of the 50 mL and 100 mL beakers, twenty half-dozen boxes of 250 mL beakers, ten dozen of the 100 mL graduated cylinders (less the six that I pulled out for the kits I’m building), and so on and so on.

What I want to know is where Obama was while I was doing all this. According to him, I didn’t do it myself. But I sure didn’t notice him helping. Quite the converse, in fact. Just about everything he does hinders people who are just trying to build and run their businesses.

09:46 – Barbara arrived home around 6:00 to loud acclaim. She thinks Colin didn’t miss her because he’s my dog. In a sense, that’s true. He’s the first-ever dog we’ve had that prefers my company to Barbara’s or my mother’s. And Border Collies generally are one-person dogs. But Colin likes Barbara, too. He made his displeasure at her absence clear the whole time she was gone, misbehaving and whining constantly. Border Collies think they’re in charge of almost everything, but there are exceptions that they concede are their humans’ responsibility. One of those things I’m responsible for is making Barbara come home when she’s supposed to. And Colin made it quite clear while Barbara was gone that I was failing in my responsibility.

I didn’t get any chemistry kits built yesterday, but I got a good start on the next batch of 30. Those are close enough to complete that I can quickly assemble one or a few as needed. At worst, there might be a one-day shipping delay. I’m going to print up another 60 sets of labels for the biology kits and 60 for the chemistry kits. Labeling and filling bottles is the most time-consuming part of building the kits, so we’ll be doing that every spare moment.


17:24 – I was just looking around Netflix streaming for something new to watch when I came across Primeval, a British show. It’s kind of a nature show, set contemporaneously, but with dinosaurs trying to eat the scientists. I watched only the first few minutes of the first episode, but I kept thinking that what these guys need is my .460 Weatherby Magnum, with armor-piercing bullets. The .460 with standard loads delivers 8,000+ foot-pounds at the muzzle, more than the .600 Nitro Express. It’s also a bitch to shoot, with free recoil of 100+ foot-pounds force. That’s about five times the recoil impulse of a typical .30-06 rifle, and more than three times a 12-gauge magnum with heavy loads. Not something you’d want one of the girl scientists on this show trying to shoot. Of course, it’ll also shoot through an elephant lengthwise, literally, as long as you don’t mind paying $14 per round.

11:55 – Barbara will arrive home this evening, and be greeted by Colin and me barking and doing our happy dance.

It’s fortunate that I got another 30 biology kits built yesterday, because yesterday and today we sold the last half dozen from the previous batch. We came within one day of running dry. Today I’m working on chemistry kits. We’re down to four of those in stock, and I’m going to try to get 30 more assembled today. Well, 25 actually, because we have only 25 small parts bags in stock. I have the components to build another hundred small-parts bags, so I’ll just go ahead and assemble 30 chemistry kits and set five of them aside until we’ve built more small-parts bags.

08:08 – One to-do item taken care of. We now have about three dozen biology kits finished and ready to ship. Today, I’ll get started on the next batch of 60 chemistry kits. Well, half-batch, really. I’ll do them in two groups of 30 each. I also need to get started on making up solutions in bulk for the forensic science kits, which we plan to start shipping by 27 August, and earlier if possible. We’re doing an initial run of 30 of those kits, and we already have pre-orders on some of those.

Barbara called last night, but the cell phone service where she was was horrible. We lost the connection on her first attempt, and when she called back she was breaking up so badly I could barely understand her. But I did hear enough to know that her dad is fine and everything is going well.

09:42 – Barbara and her family finally got on the road late yesterday afternoon. They broke their trip in Roanoke, and will finish the drive this morning. Her dad is still on IV vancomycin, which she has to administer at 9:00 p.m. daily. Colin and I are missing her, but we’re surviving so far.

Last night, we watched several more episodes of Heartland. Well, I watched, while Colin mostly pestered me to throw his toys down the hall. I wouldn’t mind if he’d just bring them to me and drop them so that I could pick them up and throw them. But that’s not enough participation to satisfy him. He brings them, drops them, and as soon as I reach for them, he grabs them away from me and then stands there whining at me. Very annoying.

Despite our mutual kidding, there aren’t really any speech characteristics that allow one to discriminate reliably between Canadians and Americans. Yes, there’s the “ou” diphthong, which most (not all) Americans pronounce to rhyme with “cow” and most (not all) Canadians pronounce to kind of rhyme with “loose”. But there are many Americans who use the “Canadian” pronunciation, and vice versa.

So, on my first pass through the five seasons of Heartland, I thought I’d discovered a speech difference. On three or four occasions, one of the characters was referring to his or her school days and used a construct that strikes American ears as strange. Where an American would say, “my third-grade teacher”, Canadians apparently instead say, “my grade-three teacher”. I thought I’d discovered something.

Then, last night as I re-watched episode six of series three, Lou was telling Amy, Ty, and Scott in detail how much work was involved in caring for an orphaned foal. Scott (the vet) asked her how she knew so much about it, and she replied that she’d done a “sixth-grade” project on the subject. Oh, well.

We ended up shipping six kits yesterday, four chemistry and two biology. So far today, we have only one order. That’s actually a bit of a relief, considering that our finished-goods inventory is now down to only four biology kits and five chemistry kits. So yesterday afternoon I brought 30 almost-complete biology kits up from the basement. They’re now sitting in the kitchen, where I’ll complete final assembly today and stack them in the finished-goods inventory area. Once I finish that, I’ll start assembling another 30 chemistry kits, followed by yet another 30 chemistry kits. Then it’s 30 forensic science kits. Lather, rinse, repeat.


12:18 – When I shipped our first science kit to Canada a month or so ago, I had to drive to the post office to have the box weighed. Even though I was shipping the box International Priority Mail flat-rate, the customs documents required an actual weight for the box. So, the other day I finally got around to ordering a shipping scale from Amazon.com, which arrived yesterday and which I used for the first time today.

The main reason I put off ordering a shipping scale so long was that I figured it’d be expensive and I didn’t really have time to do any comparisons before ordering. So I was shocked when I found a perfectly suitable scale from a good manufacturer on Amazon for $35. It’s the American Weigh Ship-Elite. It has a capacity of 50 kilos/110 pounds and resolution of 0.1 ounce across that range. The metric resolution is 1 gram up to 20 kilos and 2 grams from 20 to 50 kilos. It runs on two AA cells or the included AC adaptor, and has a remote read-out on a coiled cord.

I may actually use it in the lab as well. For example, one of the solutions included in the biology kit requires dissolving 1.5 kilos of dipotassium hydrogen phosphate in 15 liters of water. Weighing out 1,500 grams of something on a lab scale with a capacity of 200 grams is a pain in the butt. With this scale, I can weigh it in one pass, and know that I have between 1499 and 1501 grams, which at ± 0.07% is certainly close enough.


13:24 – Geez, I’d forgotten what a pain in the ass it is to pack biology kits. I was wondering the other day why we’d made a second set of goggles an option with the chemistry kits, but not the biology kits. Now I remember. When all of the components of a biology kit are in the box, there’s no room for anything more. Nothing. Not even a packing peanut. I’m even opening the ziplock bags to squeeze excess air out. These biology kits are, in the words of Veronica Mars (referring to game hens), “dense little turkeys“.

08:55 – Barbara just left to pick up her parents and sister to head up to their family reunion in Pennsylvania. They’ll return sometime Sunday.

Interesting trend on the science kits. We sold one Monday, two Tuesday, three yesterday, and five so far today. Component backorders permitting, we can sustain 10 or 15 kits a week indefinitely, but we’re still a week or so away from when the really heavy flood of orders typically commences. I’m going to take some time over the next couple of days to do a quick inventory and get POs cut for stuff we’re likely to run out of.

10:29 – Barbara’s dad may or may not be released from the hospital today. They’d planned to leave tomorrow for the family reunion in Pennsylvania, but they may have to delay their departure until Friday. He’s feeling much better, which isn’t surprising since he’s on heavy antibiotics. In addition to the pneumonia and UTI, Barbara told me yesterday that they’d mentioned that he has an S. aureus blood infection. I would imagine that they’re treating him with bacteriostatic antibiotics and are concerned that the infection(s) will come roaring back once they take him off the antibiotics.

When Barbara arrived home yesterday, she immediately asked what the terrible smell was. I’d gotten several deliveries yesterday, which were still stacked in the foyer. I’d noticed a slight musty/rancid smell but I wasn’t able to localize it. When Barbara walked into the foyer, she immediately narrowed it down to a box that contained three one-pound bags of sodium dithionite, which is a chemical that will go into the forensics kits. It’s a bleach used in fabric dyeing. The MSDS says that it has a “characteristic slight sulfurous odor”. According to Barbara, it’s anything but slight. She may be right, because those bags were heat-sealed aluminized plastic, and some odor was still able to escape.

I told her we’d be packing 25 g of the stuff in 30 mL widemouth bottles, and she immediately replied, “*You’ll* be packing…”. When I told her that in addition to the odor problem, the chemical was spontaneously combustible if exposed to air or water, she said there was no way she was going to touch it.

Speaking of hazardous chemicals (and sodium dithionite is classified as only slightly hazardous), I’m always looking for ways to eliminate shipping hazards while maintaining functionality. One of the chemicals I’d like to ship in a kit I’m designing now is universal indicator solution, which is very flammable. For some other chemicals I can get around that problem by shipping a bottle that contains only a tiny amount of the dry chemical. The kit buyer can then simply fill the bottle with, for example, drugstore isopropanol to dissolve the chemical and make up the actual solution.

The problem with universal indicator is that it contains four indicator chemicals in really tiny quantities, as in 0.03% w/v. That means that for a 15 mL bottle I’d need somehow to put more or less exactly 4.5 mg each of bromothymol blue, methyl red, phenolphthalein, and thymol blue powders in each bottle. That’s obviously impractical, but I have a cunning plan, which I intend to test when I have a moment. Rather than mess with the dry chemicals on a per-bottle basis, I’ll simply make up the actual solution, fill each bottle with 15 mL of it, and then heat the bottles at low heat in the convection oven in my lab until all of the liquid evaporates. I’ll then allow the bottles to cool, cap them, and ship them with the kits. And people wonder why my wife calls me Baldrick.

09:48 – Barbara’s dad is doing much better, and may go home from the hospital today. Apparently, he had both pneumonia and a UTI, both of which have been knocked down by antibiotics. Barbara says her dad is insistent that he wants to leave Thursday for the family reunion in Pennsylvania, but it still worries me. A 90-year-old man recovering from pneumonia should be taking it easy, not taking an 8 or 9 hour car trip. But, as Barbara says, her dad is stubborn. And Marines are nothing if not tough. At least he won’t be driving.


Today we sold our first science kit to a customer in Winston-Salem. I’m not sure why I was surprised when I saw the address. There are a lot of homeschoolers in North Carolina.

Today I need to make up a batch of 30 shipping boxes for chemistry kits. We actually have 60 chemistry kits in progress, but we do kits in batches of 30 because we simply don’t have room in the assembly area to do 60 at a time. At the moment, I’m burning DVDs for the new batch of 30 biology kits, which is the last item we need to complete the kits. We’ll get those boxed up and stacked, which’ll free up a lot of space. After we get those boxed and stacked, we’ll box and stack the 30 chemistry kits, and then start on 30 forensic science kits.
