07:23 – Happy Birthday to me. Today I turn the big Six-Oh.

Barbara’s dad still isn’t doing very well. I’ll stop over to visit him sometime today, and talk to the staff to see if I can find out exactly what’s going on. It may be a treatable infection, but we’re worried that it’s renal failure that’s causing or at least contributing to the problems. If it does turn critical, Barbara and the rest of Dutch’s family have instructed Brian Center that they don’t want him transported to the hospital. Brian Center is to contact Hospice. If Hospice has a room available, they’ll transport him there. If there’s no room available, Hospice personnel will care for Dutch at Brian Center until and if a room becomes available.


09:36 – I’m filling four liters worth of 30 mL iodine solution bottles, which reminded me that it’s time to get more iodine. So I just ordered 250 g of ACS iodine on eBay. I don’t have an account there, so I bought it as a guest. When I was filling out the address information, I entered our city as “Winston Salem” rather than “Winston-Salem” because the hyphen gives a lot of ecommerce systems fits. The page refreshed and told me to enter a correct city name. So I entered “Winston-Salem”, which it accepted. Geez. So then I get to the page where I provide my credit card information. The address was already filled in with “Winston-Salem”. When I clicked on Continue, the page refreshed and told me to enter a correct city name. So I deleted the hyphen to make it “Winston Salem”, which it accepted. Double geez.

08:13 – Barbara spent some time labeling bottles for me yesterday, and will do more labeling today. As of this morning, I have 2,288 labeled bottles that need to be filled, which, with what’s already on hand, is most of what’s needed for the next batch of 60 chemistry kits and 30 forensics kits. While she was doing that, I was making up solutions: 4 L of iodine solution, 4 L of copper(II) sulfate solution, and so on.

We’re in reasonably good shape in terms of finished-goods inventory for the moment: 41 biology kits, 25 chemistry kits, 20 life science kits, and half a dozen forensics kits. With the exception of the forensics kits, that should be sufficient to take us through June, or nearly so. With the batches already in progress and those we’ll start and finish later this month, I’m hoping we’ll be able to start July with about 90 each of the biology and chemistry kits and 30 each of the others on hand. With a few exceptions, all of which are readily available from multiple sources, we have enough component inventory on hand to build another 700+ kits. Our original goal for 2013 was to double 2012 sales, but through the end of May our actual sales have been quadruple 2012’s. If that holds up, we’ll sell about 1,000 kits this year rather than the 500 we’d planned on.

Barbara visited her dad yesterday and took lunch to him. She said he’s still doing extremely well. With his congestive heart failure and renal failure, there’s no hope of recovery, but Dutch’s personality is back to what it used to be. Barbara is taking the day off from visiting. Frances and Al are taking Sankie over to visit today.

08:30 – I didn’t quite finish the 30 biology kits yesterday. I have 30 shipping boxes arrayed on the work tables downstairs, each box filled with all of the required items, but I haven’t yet gotten the shipping boxes packed and sealed. I’ll finish that today and get started on filling bottles for the new batch of 30 forensics kits. That, and figuring out what we’re short of for a new batch of 60 chemistry kits.

One of the unfortunate realities of the business ramping up is that we end up with more and more working capital sunk in inventory, both finished goods and raw materials. I saw that coming from the first, and I was determined to fund that inventory from working cash flow, which we’ve done. The result, of course, is that we’re not taking much money out of the business. Instead, we end up with $1,000 worth of thermometers in stock, $2,000 worth of bottles, several thousand dollars worth of microscope slides, and on and on. That’s okay, for now. In fact, I’d much rather have funds in the form of hard assets rather than money in the bank. Money loses value constantly, while hard assets appreciate. And, as we begin drawing down inventory levels over the peak summer months, that inventory gets converted to cash.

The other unfortunate reality is that as volumes increase we become less cost-efficient. For example, I just got a partial shipment of some backordered items yesterday. Shipping on that small backorder was about 30% of the item cost. In the past, we would have combined orders and waited until the whole order was ready to ship before having it shipped, thereby saving on shipping costs. Now that we’re doing higher volumes, that’s impractical. One item may be the showstopper that’s holding up assembling a batch of kits, and we have neither the room nor the time to wait. So that item gets shipped by itself, which boosts our overall shipping costs. Still, we’re doing pretty well at keeping things reasonable. We’ve not yet had to resort to anything faster than ground shipping. For example, that order of bottles and caps I placed earlier this week included free ground shipping. If I’d needed expedited shipping, that would have increased our cost by about $1,000.

08:35 – We’re down to a dozen or so finished biology kits in stock, so today I plan to do final assembly on 30 more. If the month-on-month trends compared to last year hold up, we should ship between 65 and 110 total kits in June, between 100 and 160 in July, between 160 and 260 in August, and between 115 and 190 in September, so we have our work cut out for us. At least those 12,000+ bottles and caps I ordered yesterday will be enough to get us started.

10:04 – I’m cutting several purchase orders this morning for stuff like thousands of bottles and caps, 500 test tube racks, several chemicals, and so on. We’re not quite there yet, but by this time next year we may well be ordering some stuff in pallet quantities and getting those deliveries by motor freight rather than UPS.

Today I’m building biology kits, and may have time to get started on a new batch of forensics kits as well.

08:17 – It’s Memorial Day here in the U.S., the day set aside to remember those who sacrificed themselves to protect our freedom. Although the official purpose of Memorial Day is to remember those who gave their lives in the service of our country, let’s also remember all of those brave men and women, living and dead, who through the years have put their lives on the line to protect all of us. As we have our cookouts and family get-togethers today, let’s all take a moment to think about our troops in the Middle East and elsewhere, who can’t be with their families. And let’s have a thought, not just today but every day of the year, for them and the sacrifices they are making and have made.


Barbara is doing some work around the house and yard this morning before she heads over to visit her dad. This afternoon, she’ll help me with kit stuff. We’ll assemble 30 of the regulated chemicals bags for biology kits, 30 of the non-regulated chemicals bags, and 60 small parts bags. If we have time, we’ll get started on final assembly of 30 biology kits. After that, we’ll start on 30 more forensics kits and then 60 more chemistry kits.

Barbara finally took pity on me last night. We’d watched one 90-minute episode of the British series Vera on Netflix streaming the other night, and were part way through the second episode last night when Barbara suggested we bag it. The problem was that I had no clue what was going on because I could understand only a small fraction of the dialog. Some of the characters might as well have been speaking Martian. We watch a lot of British TV, and normally neither of us has any problem understanding the accents, but this series badly needs subtitles for US viewers. And probably for some British viewers as well.

09:19 – I wanted a nice, peaceful, relaxing diversion for Barbara, so we finally started watching series six of Heartland last night. I was surprised that she wanted to watch all three episodes on the disc. Usually, she prefers to mix it up, with episodes from two or three series over an evening.

As most people who follow the series know, Ty and Amy don’t get married in series six. This is getting ridiculous. They’ve been a couple since series one, but have been constantly breaking up and getting back together. Enough is enough; they need to marry those two kids off.

I emailed Heather Conkie, one of the four executive producers, to suggest that she really, really needs to get Ty and Amy married early in series seven. If nothing else, the fact that Amber Marshall is now Amber Marshall Turner should introduce a sense of urgency. Amber, like her character Amy, is an Earth Mother in waiting–both the actress and the character nurture every living creature in sight–and it wouldn’t surprise me a bit if Amber decided to get started quickly on having a family. So, unless they want to be shooting Amy from the shoulders up, it’s past time to get her character married off.

We now have everything we need on hand to build another 30 biology kits, and much of what we need for 30 more beyond that. Today, we’ll start on getting things together for another 30/60 forensics kits and another 60/120 chemistry kits.


10:59 – Urk. I was just thinking it was time to order some more iodine crystals. I’d ordered 250 g a year ago from an eBay vendor, and Googled his company name to find the web site again to order more.

Unfortunately, I’ll need to find another source of iodine. The guy I bought from a year ago is in a world of trouble with the feds, not just for possession and sale of List I chemicals, but on charges of firearms possession by a felon and possession for resale of controlled-substances. I’ve never heard a word from the feds, and don’t expect to. No one who planned to manufacture methamphetamine would be buying a quarter kilogram of iodine crystals; they’d want the stuff in large amounts. I’m just glad that I reconsidered my order before placing it. Originally, I’d intended to buy a kilogram, which might have raised some red flags.

10:18 – Barbara is trying hard to keep things as normal as possible despite her dad’s condition. She refuses to go over to the nursing home and just sit there all day watching him die. I think that’s the best decision. Dutch is sleeping most of the time anyway, and when he’s awake he’s often so confused that it’s difficult to hold any kind of conversation with him. Barbara wants to remember her dad as he was, not as he is now. At our age, she’s been lucky to have him around all of her life, and in pretty good shape until recently. And, like me, she’s been lucky enough to live locally to her parents rather than living across the country and being able to see them only once or twice a year.

So at this point, the emphasis is going to shift to doing what she can for her mom, to help her get past the inevitable loss of her husband of almost 70 years. In fact, Barbara and Frances are heading over to their mom’s apartment today to do some stuff and then take her out to dinner.

During her four-day weekend, Barbara is also getting some stuff done around the house and yard, and helping me build new batches of science kits. I haven’t booked the 20 kits we sold earlier this week to a small private school, and won’t until we receive the check and it clears. Even so, we’ve already done three times the business so far this month that we did in May 2012, and kit sales continue to accelerate.

08:09 – Barbara’s dad is back at Brian Center. Barbara called me yesterday about 12:25 to let me know he had left the hospital and was on his way. I stopped at Harris-Teeter on the way over to pick up a six-pack of Pepsi and a couple cans of sliced Mandarin oranges for Dutch, which he’d requested. Then I spent an hour or so talking with his new roommate and his sister while I waited for Dutch to arrive.

The privacy curtain was drawn between the two beds, and as I was talking to the sister a woman on the other side of the curtain asked, “Who is that speaking?” I told her my name and that I was Dutch’s son-in-law. She replied that I had a beautiful voice and asked if I was on the radio. For some reason, people frequently ask me that.

After Dutch finally arrived, I visited him for a while and then headed back home. As I was walking to my truck, I saw one of the nurses, Jodi, coming in the opposite direction. Over the time Dutch has been at Brian Center, I kept thinking that she looked familiar. She’s far too young to have been there when my mom was there 10 years ago, but I kept thinking I must know her from somewhere. So I finally asked, “Do I know you?” She stopped and said she’d been thinking she knew me too. We talked for a while about where we might have met, but we couldn’t come up with any explanation.

Barbara is taking today off to give herself a four-day weekend, so we’ll be doing kit stuff over the next few days. I got another query yesterday from someone who wants to buy multiple forensics kits for a class, so we need to get another batch of those in progress as well.


11:08 – Barbara and I started watching Switched at Birth on Netflix streaming. We’ve watched only two or three episodes so far, but the cast and writing are both very good.

The story centers on two high-school girls who were, uh, switched at birth. In the first episode we discover how they find out it had happened, and I thought that was interesting because in one of the biology book lab sessions, we warned strongly about just such an event. That lab session was on using PTC to track the tasting and non-tasting alleles within a family group. In the program, one of the girls was doing a biology lab that determined her blood type. She soon discovered that genetically she couldn’t be the child of her supposed parents. Same concept, different alleles.

One of the girls is deaf. Given her speech patterns, I was very surprised to learn that the actress is actually capable of speaking like a hearing person, but intentionally assumed a “deaf accent” for the role. She grew up hearing, and didn’t start to experience hearing problems until she was 20 years old, about five years before she started work on this series.

It’s interesting for me to watch a series that features deaf people and deaf issues, because I had some experience with deaf people when I was at RIT in the mid-70’s. RIT is home to NTID (the National Technical Institute for the Deaf), and roughly half of the students I regularly associated with were deaf.

The series does portray the ability to lipread as both more common and more successful than was my experience at RIT. One evening, I walked into the lounge and found the TV tuned to Carson’s monologue with the sound off. There were a dozen or more students sitting with their backs to the TV, and one student standing facing the TV and interpreting the monologue in ASL. Thinking that any deaf person could learn to lipread, I asked her later. She explained that many/most deaf people couldn’t lipread at all, and that the ability to do so varied greatly even among those who had some ability. She was among the best lipreaders she knew, and said that even she often missed things or interpreted them incorrectly. That was why she sometimes paused while interpreting when she was uncertain about what was being said and wanted to wait for context before interpreting something.

I started to learn ASL, beginning of course with the most important things: swear words, how to proposition a girl, ask for a beer and so on. As I told Barbara, in my experience deaf people have better-than-averages senses of humor, and some of them are absolutely wicked. I remember sitting around with a group of girls while I was trying to learn to sign. With completely straight faces, they attempted and eventually succeeded in convincing me that, when signing, deaf people had regional accents just like hearing people. They said they could always tell when someone was from the deep South by the accent of their signing. I sat there trying to figure out how that could be true, and eventually decided that it must just be that local ways of signing used slightly different gestures. Once they finally had me convinced, they looked at each other and started to laugh. I finally realized I’d been had by experts. And that was just the first of many examples of the wicked senses of humor that many of my deaf friends had.


13:35 – I can’t believe it took me this long to think of it. Barbara was filling several hundred RIA (radioimmunoassay) vials this morning. She was working at the kitchen table because she was filling obnoxious ones, like black fingerprint powder and activated charcoal, which put up clouds of filthy black dust. She was filling them using a pointy scoop, when it struck me. This would be an ideal application for a powder measure. Fill up the reservoir with the stuff being filled, hold the mouth of the tube under the dispensing spout, throw a lever, and you’re finished loading that tube. Just like handloading ammunition. The powder even resembles gun powder, and the mouth of the vial is the same size as a .44 or .45 case. I can’t believe it took me that long to think of it. It’s not like I haven’t sat at a reloading bench and filled tens of thousands of cartridge cases with powder using just such a powder measure.

07:29 – Barbara’s dad is likely to be released back to the Brian Center in the next couple of days. Brian Center called Barbara yesterday to ask if she wanted them to hold his room. She told them yes, even though they’ll have to pay something like $275/day themselves to hold the room. (Obviously, Medicare isn’t going to pay for Dutch to be two places at once.) Barbara was concerned that otherwise Brian Center wouldn’t have a room available when her dad was discharged and he’d end up somewhere else that wasn’t very good.

We had an all-time record for kit orders yesterday, with 21. Of course, 20 of those were to one customer, a small private school. Still, that means that through the first five months of 2013 our kit sales and revenues are more than 50% of the total for 2012. And in 2012, we did only about 10% of the year’s business in the first five months. So of course we’re desperately trying to get more kits built in time for the summer rush.


16:35 – Geez. Colin just scared the shit, almost literally, out of the replacement mail carrier. The front door was open, with just the glass storm door between him and the mail carrier. Colin acts like a berserker when someone approaches the door. Fangs, snarling, loud barks, ramming into the glass, and so on. I’m not even slightly afraid of dogs, but given Colin’s threat display I sure wouldn’t want to mess with him. A pissed-off dog that weighs 80 or 85 pounds is no joke. Of course, if I’d opened the door and let him out, he would have made a big fuss over the mail lady, licking her hand and so on.

But I yelled at him to shut up and then opened the door and went out. The mail lady summed up her feelings pretty well. She asked me, “Are there just the two of them?”
