10:42 – We’ve been screwed again by Roku. After we ran the Ethernet cable from the den to the router, everything worked fine. No delays, very good picture quality, and no drop-outs for re-buffering. Then, yesterday, I fired up the Roku box to watch some Netflix streaming. Roh-roh. The first indication of a problem was the time needed to buffer. Ordinarily, I see the buffering bar for maybe 10 or 15 seconds, and then the program starts playing in HD. This time, it took literally two or three minutes to buffer. I then got about three seconds of HD before it dropped the signal and started re-buffering. This time, it took three or four minutes to buffer, and the video quality was showing two balls rather than the usual four balls + HD. The program then ran for about two minutes before it blew up again and started re-buffering.

My first thought was that we might be having network problems with TWC, so I went to my office and ran some network tests. Our download speed was between 13 and 14 Mbps (HD streaming takes only 5 Mbps), and the latency looked fine. So I figured Netflix might be having problems and called their tech support. The guy told me there were no problems on their end, and then said, “Oh, wait a minute. You’re using a Roku box.” As it turns out, Roku pushed down a firmware upgrade earlier that day, and the Netflix support guy said it had “buried” them. He said there were two things that would solve the problem. He suggested first powering down the Roku box and our router, waiting a minute, and powering up the router and then the Roku box. If that didn’t work, he said to deactivate the Roku box and then reactivate it. He said that would solve the problem.

I did the power-down thing. No joy. It was still taking three minutes to buffer and then dropping the signal. So I took a deep breath and started the de-activate/reactivate procedure. (When I first set up the Roku box, that “five-minute” job took four hours, much of which was spent on the phone with Roku tech support, who speak only extremely Chinese-accented English.) I de-activated Netflix, did a factory reset on the Roku, and went through the procedure to re-activate. This time, it indeed took only a few minutes. But… No joy. Three minutes of buffering, followed by 2-ball video quality and frequent drops.

So I called Netflix tech support again, and told the woman who answered what I’d done. She said that one or the other of the things I’d done should have solved the problem, but said they did have a list of four or five other things I could try. She emailed that to me, and all of them had to do with wireless problems. So at this point I’m stuck. Netflix doesn’t know what else to tell me, and suggests the problem must be with my broadband connection. I’ve tested that, and it’s fine. It would be an amazing coincidence if this problem, which started when Roku pushed their damned firmware upgrade, wasn’t related to that upgrade. But there’s no way I’m going to call Roku tech support, which is as abominable as any tech support operation I’ve ever spoken to.


Talk about just-in-time inventory. UPS showed up late yesterday afternoon with a bunch of boxes from one of my wholesalers. Among them somewhere is a crate of 144 250 mL beakers, which is all I lacked to make up the batch of 30 chemistry kits that’s sitting waiting for beakers, as well as the new batch of 60 that’s currently in progress. And we’d better start thinking about making up more biology kits, too. We have less than 20 finished biology kits in stock and components to assemble 30 more. Sometime in the next few days, I’ll run 60 sets of labels for the biology kits and get Barbara started on labeling bottles.

08:10 – I see that the mayor of Scranton, Pennsylvania has cut the pay of all city employees, including himself, to minimum wage. Predictably, the howls of outrage, particularly from the public employee unions, are loud and continuous.

A basic principle of economics is that if qualified people are lining up to apply for jobs with you, you’re paying too much. And there’s no doubt that many of the government jobs in Scranton are overpaid, as are most jobs with most government organizations. I shudder to think, for example, what Winston-Salem pays garbage collectors, a job that’s minimum wage by definition. These people aren’t even required to be able to read.

A minimum-wage job pays roughly $15,000 per year. It seems to me that government at all levels should have three tiers. At least 50% of government employees–garbage collectors, clerks, and so on–should be making minimum wage to 2X minimum wage, with the average for those 50% no higher than 1.5X minimum wage. The second tier, 45% of government employees, should be in the 2X to 3X minimum wage–call it $30,000 to $45,000 per year, with the average for that group no higher than 2.5X minimum wage. That group includes police, firefighters, teachers, and so on, along with most federal employees. The final 5% should be at 3X to 4X minimum wage–$45,000 to $60,000 per year, with the average for that group no higher than 3.5X minimum wage. That group includes management.


11:35 – If you’ve ever wondered what I went through shooting videos for my TheHomeScientist channel on YouTube, here’s a true-to-life example. It’s the uncut version of what was to become a 21 second promo for Heartland. Graham Wardle (Ty) and Amber Marshall (Amy) star in the promo. Amber is a consummate pro. Graham is kind of like me, except he doesn’t make (quite) as many mistakes or need (quite) as many reshoots.


12:58 – Speaking of shooting videos for my YouTube channel, it’s about time I started doing some new ones. I posted the most recent one two years ago next month, and between writing books, starting the business, and doing kits, I just haven’t had time to shoot and edit any new ones. Amazingly, I still have something like 8,000 or 9,000 subscribers.

My current camcorder is an SD unit that records to mini-DV tapes. There was some discussion in the comments recently about an HD Canon model that records to flash memory and has an audio input. I suppose I should order one of those. There seems little point to recording SD video when a decent HD camera for my purposes sells for $300.

I suppose I should start my first new video by shouting “Stop! Don’t pay the ransom! I’ve escaped!” Or something like that. I’ve been MIA for two years now, and some of my subscribers are likely to be surprised at my return. I suppose I’ll just tell them what I’ve been doing all that time, as well as announcing the biology book and the forensics book, along with their kits. Then I have some good ideas for follow-up videos about some really neat stuff. Some of it’s trivial, but obscure. For example, a lot of home scientists occasionally need some 30% hydrogen peroxide. You can order it from a lab supplies vendor, but it’s fairly expensive and in anything but the smallest amounts requires paying a hazardous shipping surcharge. But there’s a trivially easy method that requires no special equipment to concentrate drugstore 3% hydrogen peroxide to 30% or higher. I think I paid something like $1.59 for a quart (almost a liter) of 3% hydrogen peroxide at Costco. That’ll yield about 100 mL of 30% peroxide.

Sometimes the USPS rates make no sense whatsoever. We normally ship kits in a USPS Priority Mail Regional Rate Box B. I just processed an order for two chemistry kits from a woman in California, which is Zone 8. Those two boxes would have cost $15.46 each to ship in the RR Box B, but substituting a Priority Mail Large Flat Rate box cuts the cost to $14.65 each. The FR box is larger than the RR box and its weight limit is 70 pounds, versus 20 pounds for the RR box. So why is the FR box $0.81 cheaper to ship to Zone 8? I just slide each pre-packed RR box into a FR box and thereby saved myself $1.62.

12:07 – My life has become a steady stream of building science kits, processing orders for them, and shipping them. Not that I’m complaining. I wish it could be like this all year long. Instead, it’s semi-crazy in July, full-on crazy in August and September, and back to semi-crazy in October. Still, as long as we can continue to build enough kits to meet demand, and assuming the current sales trajectory holds up, it looks like we’ll reach my goal for the year in September, if not August. The remainder of the year should allow us to exceed the goal comfortably.

And to think that back around April/May, I was seriously considering starting another book in the DIY science series and designing another kit. As it is, I’ll be hard pressed to get the first batch of forensic science kits ready by the time the book hits the bookstores in about a month. I haven’t even started making up the solutions, of which there are a large number, other than in prototype quantities. As a very smart friend of mine once commented, “We can do anything, but we can’t do everything.”

08:55 – It’s still early July, and the rate of kit orders is starting to scare me. We’re already shipping them faster than we can build new ones, and the rate of orders is accelerating. We’ve had four kit orders so far today, and it’s not even 9:00 a.m. From everything I’ve been told, the order rate in August and September is likely to be at least three or four times what it is now.

I remember laughing to myself when I read the USPS page about scheduling pickups. It said they didn’t need an exact package count, but they needed to get some idea so they’d know whether or not they needed to send out a separate truck. At this point, that may not turn out to be funny. Those 30 chemistry kits in final assembly and 60 more chemistry kit currently a-building may not last long. I was planning to do 30 more biology kits next, but we may do 60 more instead. And we’re down to less than 200 shipping boxes, so I need to re-order those from USPS.

08:34 – Barbara is taking a break this morning from labeling bottles to work out in the yard before it gets too hot. I’m doing laundry and other normal Saturday tasks. This afternoon, Barbara will be back to labeling bottles and I’ll be making up solutions and filling bottles. Finished kit inventory is currently at comfortable levels and building.

I spent some time yesterday reviewing and editing the cover for Illustrated Guide to Forensic Science Experiments. All that remains is a quick QC2 pass and then the book will be off to the printers. It’s currently scheduled to hit the bookstores on 12 August. By then, we need to have the first batch of forensic science kits ready to ship.

Barbara and I have been watching Lying Little Pretties on Netflix streaming. My favorite of the four is Spencer, played by Troian Bellisario. I can’t help liking a girl who, while playing Scrabble with her boyfriend, fills in “glyceraldehyde”. I do wonder where she got all those tiles, though.


09:32 – I should remember this stuff, particularly when I’ve left myself notes. I have sheets of paper taped to the cabinet doors in my lab. They’re instructions for making up chemicals for the various science kits. So, this morning I was making up two liters of 0.1% methyl orange indicator. The instructions are as follows: “Methyl Orange, 0.1% – Dissolve 2.00 g of methyl orange powder in about 1.8 L of hot DI water. Cool and make up to 2.00 L.”

So what did I do? I boiled 1 L of DI water, added it to 1 L of room-temperature DI water, and added 2.00 g of methyl orange powder. The water was about 140 °F (60 °C), which most people would consider “hot”. Not hot enough, obviously. Maybe half of the powder dissolved, with the remainder forming clumps that settled to the bottom of the bottle.

So now I’ll decant off about half of the solution, leaving the undissolved powder and maybe a liter of the dilute solution. I’ll boil that and hope the clumps dissolve. If not, I’ll discard what I have and start over, this time with boiling water. And I’ll update the instructions from “hot” to “boiling“.

10:18 – I got the first kit shipped to Canada yesterday. Per the advice of the woman I spoke to on the USPS toll-free support number, we hauled the kit out to the local post office to have them weigh it and look over the paperwork. I told the guy at the counter not to print postage because I was going to take the kit home and use Click-and-Ship. He said that the paperwork looked fine, but mentioned that Click-and-Ship did all that for me for international shipments.

So I took the kit home, hit the USPS Click-and-Ship web site, and told it I needed to ship a Large Flat Rate Priority Mail box to Canada. Sure enough, rather than the four or so screens that I see for US shipments, there were eight or ten screens, most concerned with customs issues. The only strange part was that when I filled out the manual six-part paper form, per the instructions I’d gotten on the phone earlier, I entered “30.37a” in the EEL field. On the web form for that field, there was a drop-down list, and the only choice was “NOEEI 30.36”. So I did the best I could, and eventually got to the part where I pay and generate the postage label.

I paid (with Barbara’s AmEx because I still don’t have my replacement card) and told it to generate the label. For US shipments, the postage label is a half-sheet. I can choose to print a full sheet with half being the postage label and the other half the receipt, or simply print postage labels two-up if I have multiple kits to mail. I always download the label as a PDF and then print it. In this case, the PDF was three full pages. Two pages of two-up labels and a third page of instructions, which weren’t all that helpful.

I had four half-sheet labels, all of which looked very similar but with minor differences. They all had the same barcode, but one had a second barcode and a “postage paid” line on it. I assumed that was the one I was supposed to stick on the box and the other three were to go into the clear plastic envelope. Just to make sure, I called USPS International Mail support and spoke to a woman who clearly had no idea what to tell me, nor later did the mailman when he picked up the box.

The manual form 2976-A had six parts, with the original being “1 – Manifesting/Scan Copy”, the second and third pages being “Customs Declaration”, the fourth “Dispatch Note”, the fifth “Post Office Copy”, and the sixth “Sender Copy”. The web-fill version had only four parts, “1 – Customs Declaration” (with the postage barcode), the second “Customs Declaration”, the third “Dispatch Note” and the fourth “Sender Copy”. The “Manifesting/Scan Copy” was missing, as was “Post Office Copy”. I assumed that those were taken care of by the Click-and-Ship automation, so I stuck “1 – Customs Declaration” on the box, since it had the postage bar code, and put the other three copies in the 2976-E clear plastic envelope.

11:03 – We’re shipping our first chemistry kit to Canada today. I’ll haul it out to the local post office and ask them to take a look at it and the paperwork, and to weigh it just to make sure what it actually weighs. Then I’ll haul it back here, print the Click-and-Ship postage label and hand it to the letter carrier this afternoon.

I also need to stop by the lawn and garden store and pick two or three bags of vermiculite. One bag is four cubic feet (100+ liters). To meet shipping regulations, we pack chemicals in gallon (3.79 L) ziplock bags with a liter scoop of vermiculite added to serve as cushioning and absorbent, so one bag suffices for about 100 kits.

I spent most of yesterday making up solutions for chemistry kits. Barbara spent the day labeling, finishing 1,590 containers, which gave us 30 forensics kits’ worth. That’s one set of 30 labels for a 125 mL bottle, 20 sets for 15 mL bottles, 15 sets for 30 mL bottles, six sets for 30 mL widemouth bottles, and 11 sets for envelopes. She’d previously labeled a dozen sets of envelopes, so that means the forensics kits total 65 containers each.

And I just got off the phone with Crucial. Apparently, someone attempted to use my credit card number to place a $585 order on Tuesday. The Crucial rep said their internal security flagged the transaction immediately. They hadn’t actually run the charge through, but had only placed a query with AmEx to verify the card was valid and place a $585 reduction in our available credit. The rep said that they didn’t actually charge a card until the order shipped, which it obviously never will, so AmEx would automatically remove that $585 placeholder.

I wish our legal system would begin dealing with thieves as they used to be dealt with; at least as severely as murderers. Britain used to hang thieves, which unquestionably had a deterrent effect on the particular thief being hanged as well as on other would-be thieves. I’ve always thought Winston-Salem would be a much better place if, one weekend, we had a mass execution and hanged, say, the worst 1,000 people in Winston. Thieves, rapists, child molesters, politicians who lie or steal, scammers (particularly those who focus on the elderly), spammers, and so on.

Happy Birthday USA!

As you celebrate Independence Day today, please take a moment to think about the men and women of our armed forces, past and present, who have willingly risked, and all too often lost, everything to defend our freedom. I worry about America, but there can be nothing very wrong with a country that continues to produce men and women like them.


08:43 – Today also marks eight years for us being Microsoft-free. We’ve been using free software exclusively since 4 July 2004.

Today, Barbara will get started on labeling close to 4,000 containers, enough for 60 more chemistry kits and 30 forensics kits. Meanwhile, I’ll be downstairs, packing up the 30 chemistry kits that are in-progress and making up solutions for 60 more, as well as the first group of solutions for the forensics kits.


15:39 – AmEx security just called me to report that there were questionable charges made on my card. They’re issuing me yet another new card. This happened Christmas Day of 2011, and it’s getting to be really annoying. The questionable charges both occurred yesterday: a $1 charge by Groupon and a $585 charge by Crucial/Micron.

The Groupon charge is completely fraudulent. I have never charged anything with Groupon or given them my card number. The Crucial/Micron charge is fraudulent in the sense that I didn’t make it, but because I have done business with Crucial using that card, AmEx couldn’t void the charge. I’d ordered a $30 memory kit from Crucial/Micron a couple of weeks ago. So tomorrow I have to call Crucial/Micron and give them hell. They weren’t supposed to retain my card number. If they didn’t, how could they have placed that $585 charge yesterday? And why did they place a $585 charge when I hadn’t ordered anything?

09:35 – We’re officially out of chemistry kits, in the sense that the last assembled kit in inventory is spoken for, although not yet actually shipped. Fortunately, we have 30 more chemistry kits sitting partially-assembled, so I can put together kits on-the-fly as needed. We’ve also started on new batches of 60 chemistry kits and 30 forensics kits, which we’ll work on over the holiday. Meanwhile, UPS is supposed to deliver several thousand bottles and caps today. And Barbara’s new system is still sitting partially-assembled on the kitchen table.


16:48 – UPS showed up a couple hours ago with eight cartons of bottles and lids–several thousand of them. That’s fortunate, because I just finished printing about 4,000 labels.

14:37 – I’ve spent most of the morning on the phone, on-hold, being transferred among, and talking with representatives from various US government organizations, ranging from the US Postal Service to the Department of Commerce to the Department of Defense to (I am not making this up) the Census Bureau.

I was trying to find out how to fill out a form properly, more particularly PS Form 2976-A Customs Declaration and Dispatch Note. The Census Bureau was actually the starting point, where the instructions on the form directed me for information about filling out Box 11, which is descriptively named “EEL/PFC”. I might have figured it out myself if they’d used the expanded form: “Exemption or Exclusion Legend/Proof of Filing Citation”.

I learned that I really, really wanted an EEL rather than a PFC, because the latter is a lot more work. The EEL is basically the quick-and-dirty no-paperwork option. To use it, you must meet two requirements. The first was easy enough. The value of the individual shipment has to be $2,500 or less. Our kits sell for about a tenth that or less, so that wasn’t a problem. But (there’s always a “but” with government crap) the second requirement was that the shipment contain nothing restricted. Restricted in the sense of having potential military or terrorist uses. Stuff like ultra-centrifuges for separating fissionable isotopes. After spending three hours on the phone, with everyone saying “I don’t think high school science kits will be a problem, but you need to make sure…” I finally got to someone who knew how to resolve the issue. I visited a web page where I could “self-qualify” as exempt. So now all I need to do is write “30.37a” on line 11 (and possibly “EAR99” although I couldn’t get a definitive answer for that) and on line 17 “NLR” or “No License Required”. I think.

So then I called USPS support to verify that I knew exactly how to fill out the form. The woman I spoke with said everything sounded fine. In fact, she thought I could just leave lines 11 and 17 blank, but said it wouldn’t hurt to write what I’d been told to write in them. She also suggested that for the first shipment I should visit the local post office just to verify that everything was correct. So, Thursday (Wednesday is a USPS holiday and I didn’t want to ship the day before a holiday) I’m going to drive to post office and ship my first kit to Canada. We’ll see what happens.


We got four chemistry kit orders yesterday, which took us down to only three remaining in stock. I’m not too concerned, because we have everything necessary to assemble another dozen quickly, followed by 18 more once the shipment of beakers arrives. But we did decide to boost the size of the next batch of chemistry kits from 30 to 60, because these things are starting to sell pretty quickly.

I also posted a forensics landing page and forensics kit page. As of now, we’re accepting pre-orders for the forensics kits, although we won’t be shipping them until next month.
