I Bond Interest

I bought an I Series savings bond last year and then another one this year. Since they are indexed to inflation, they have been earning a lot, though ultimately you gain nothing in purchasing power. The rules for I bonds can be pretty complex, like anything involving the federal government. The bonds earn interest every month, but it seemed very odd that both of my bonds, bought 3 months apart and earning different interest rates, were worth exactly the same amount of $10,236.00 (both purchased originally for $10,000). One part of it is that the amount the US Treasury tells you is the value does not reflect the last 3 months of interest since you forfeit 3 months of interest if you redeem the bonds before 5 years (and you can’t redeem them at all the first year, so I guess they are worth nothing right now). I also thought it was odd that the bond value each month has always been to a whole dollar amount, though since my principle was a very round number of $10,000, maybe that isn’t entirely unlikely. However today I found out more about how they calculate the actual monthly interest and decided to make a spreadsheet to try to keep up with it instead of just checking in with US Treasury. I like that it is all based on rules and ultimately I was able to replicate Treasury’s numbers. It helps that I found a wiki page at Bogleheads that explained it, but I still had to do the calculations myself before I could really see what was happening. The really weird part of it is that Treasury calculates interest on any size bond as if it is a bunch of individual $25 bonds. Then they round off the interest earned on the $25 bond to the nearest penny. So if you were to earn 1.73% interest on $10,000 you might expect to end up with $10,173. But because a $25 bond would be worth $25.43, you earn as much as 400 $25 bonds, or 400 * $25.43 = $10,172. It’s only $1, but if you are trying to verify the numbers it might throw you. Since I have 400 $25 bonds and the interest on those $25 bonds is rounded to the penny, the value of my bonds will not only always be to the nearest dollar, but the nearest $4 since 400 * $0.01 = $4.00. Also, while the bonds earn interest every month, the interest is compounded every six months. So they calculate the interest on the original amount for 5 months before adjusting the principle on the sixth month (which is also when the interest rate changes). That is a little tricky too.

The other part is how to take out the most recent 3 months of interest. I was trying to think of a formula that would do it, but would be smart enough to be able to accommodate when the interest rate changes during that 3 months. But since I was calculating the value for every month anyway, it was easy to just say that today’s reduced value is the same as the full value from 3 months ago. Really easy. Once I did all of that I was able to regenerate the numbers, but a lot depends on the roundoff of the $25 bond.

The interest rate itself is always rounded to 2 decimal places and is based on the CPI-U numbers published by the Bureau of Labor Statistics. Since BLS publishes the inflation rate monthly and the last one before the bond rates change comes a couple of weeks before you can actually predict the rate that Treasury will use. The unknown part of Treasury’s rate announcement is the fixed rate that Treasury gives, but for years they have made that really easy by having a fixed rate of 0%. With interest rates still pretty low right now, but inflation very high, I thought Treasury might make the fixed rate negative, but they haven’t done that. Even during deflation when inflation is negative, the savings bonds never lose value and the earnings rate doesn’t drop below 0%.

There are other bonds that Treasury sells on the market called TIPS which are inflation adjusted, but because inflation is so high the yield determined at auction has been negative lately so that the true yield ends up below the inflation rate. TIPS are weird too because they only pay a dividend of the auction rate while the principle value of the bond varies with inflation, so the dividend you receive would be at least 1/8% (not negative since then you would have to send them money) and they apply the negative portion by reducing the principle. So you don’t get barely any dividend and the principle ends up not keeping up with inflation. The downside of the I bonds is you can only buy $10,000 in a calendar year.

Tire Repair Kit

When I bought my Ford Escape in August 2020, it did not include a spare tire, not even one of the miniature tires. Instead it included an electric air pump that you plug into the lighter socket, called the “Tire Sealant and Inflator Kit” or “temporary mobility kit”. It includes a switch that can activate a canister of latex to repair a tire if it had a leak, but this would be ineffective if the hole was too large or if you had a blowout. The latex fix was temporary and ideally would get you someplace that could do a better fix. It seems like I read somewhere that once you used the latex, the tire would never be good again and would have to be replaced, but the owner’s manual doesn’t say that, just that you have to replace the valve stem and tire pressure monitor for that tire. The advantage of this system is it is lightweight, compact, and cheap, reducing weight of the vehicle, increasing mileage, and increasing space in the car. For the hybrid the tire well is also where they decided to put the 12V car battery, so no way to just get a tire. It is also easier to operate than using a jack, removing lug nuts, and replacing a tire. However, the latex canister expires in 4 years and has to be replaced. The disadvantage of this system is you can’t go that far or fast once you do the repair (like with the mini tires) and doesn’t work if damage is severe. The mini tire was a compromise compared to having a full size tire, and this inflator is a further compromise.

In the previous couple of weeks I had driven the car to Washington, DC without any incident, but I was driving a few miles to Jeb’s house when the car alerted me about low tire pressure in my right front tire. The car has a display for pressure in the tires and the other tires were all okay, so this wasn’t just a seasonal thing. The pressure was 25 psi and the other tires were around 30-32 psi. Very quickly as I continued to drive it dropped to 21 psi and I thought I might not make it to Jeb’s. As I found a place to pull over it was down to 18. As I parked it was 16 psi. I got out and could hear air escaping the tire and could even feel the air coming out of the tread. Time to try out the kit!

Tea

Lately I thought I should try drinking unsweetened iced tea in lieu of one of my usual Diet Dr. Peppers. I even bought some tea at the grocery store and made it a few times. I generally like sweet tea more than unsweet, but unsweet isn’t bad at all and it was nice to make a big insulated mug full of iced tea and drink from that all afternoon. I even found some green tea in my cupboard from when I tried to do something similar a year or so ago and would drink that sometimes.

Thai Iced TeaMeanwhile, I had a month of free Amazon Prime and I started thinking about making Thai iced tea. I had this first in Thailand in the late 1980s, but you can often get it at Thai restaurants here, but it really adds to the bill. At first I thought Thai iced tea was just tea made with sweetened condensed milk, but looking into it further it seems to have added flavors including vanilla, cardamom, and maybe star anise. If you gather the right spices you can make something similar with black tea. You can also buy a bag of Thai iced tea mix from Amazon that has everything in one giant one pound bag of loose tea, which is what I did. Since the only ingredients on the package are green tea and yellow food coloring, I’m not sure what exactly the mix consists of (it is certainly not actual green tea). Some sources say that Thai iced tea was originally made with Ceylon tea which has a distinctive orange color when mixed with milk, but now wild Thai tea is used instead, adding yellow food coloring (Yellow No. 6 which California says causes cancer and which Kraft no longer uses to color Macaroni and Cheese, but I feel like is probably pretty safe). I’m not sure if spices are also added or whether wild Thai tea just has these extra flavors that people are trying to replicate. Maybe a little of both. A lot of the online recipes make substantial changes to the original flavor of the Thai drink, including some who add cinnamon or use other kinds of milk. I’d rather get something similar to the original.

Oscars 2022

Two years ago, the Oscars broadcast had the lowest ratings ever. Last year, the ratings dropped to half of the year before. This is despite many efforts to improve the broadcast, including nominating ten movies for Best Picture instead of just five like the other categories. The idea behind that was that if they nominated more movies, more people would be engaged, rooting for their favorite. But instead the Academy just nominated 5 more movies that nobody watched. The biggest blockbuster nominated for Best Picture this year was Dune, which was the 13th highest grossing movie of 2021. Second was the acknowledged box office disaster, West Side Story at No. 38. Some of the movies barely had a box office because really they were intended for a streaming service. That was okay during Covid when nobody could go to theaters, but in 2021 things started opening up. These highly artistic movies that nobody sees should probably be in a separate awards show. Likewise, movies meant for streaming shouldn’t qualify for Oscars at all: they are television, see you at the Emmys. I don’t think Spider-Man: No Way Home really deserved a Best Picture nomination just because it dominated the box office, but neither did a movie like Drive My Car which was in Japanese and had a US box office total of $310,000. And Netflix’s Power of the Dog had barely more than that (the Academy only requires an extremely limited run in L.A. and New York). Maybe set the bar a little higher for the release and add in a metric for ticket sales. And if you can’t sell more tickets than that, you just don’t qualify for consideration. This year the field of nominations was dominated by movies almost nobody saw. I saw 9 of the 10 Best Picture nominees, but hadn’t even heard of The Lost Daughter, which had 3 nominations. Too often studios are counting on an Oscar nomination to sell tickets instead of the other way around. Instead they introduced a Fan Favorite idea to pick a movie and a best scene, which were both pointless. A scene I had never seen or heard of was named the best scene and I had never heard of the favorite movie. Stay in your lane and let other awards shows do a better job of recognizing popularity. As much as I don’t care for the Academy focusing too much on unpopular movies, at least that gives them some integrity as one of the few awards that comes closest to recognizing merit. Ultimately nobody needs to feel sorry for Spider-Man, which made billions of dollars.

TV Repair

Last night I was watching the Oscars. I was a couple of hours in and Billie Eilish was singing her James Bond song (minutes before Will Smith punched Chris Rock) and the picture went out. I could still hear singing, but no picture. I turned the TV off and then back on, but got the same result, plus a sizzling noise. Eventually I noticed a pretty strong smell of burning electronics. The TV sometimes would have a darker than normal screen that I could reset by unplugging the TV, but this was worse than that and obviously something was physically wrong given the sound and smell. First I looked up whether it might possibly be under warranty. I had used my Best Buy credit card to buy it at Best Buy so I could get 6% cash back, but the Best Buy card does not double the warranty, which wouldn’t have helped either since it turns out I bought it more than 2 years ago. TV’s have been getting better and prices have been dropping, so I shopped a little to see what was out there, but it would clearly be $1000 to $2000 to get another 75-inch TV that was any good.

Then I started looking for other people who might have had similar problems. I did find some things, but not for this particular model of TV, the TCL 75R615. There are places that sell replacement circuit boards that can often fix the problem, but there are 4 main boards where the problem could be. The other possible problem source would be the LED’s that backlight the screen, which are harder to replace. It seemed like it would be the power board, given the sizzle and smell. It seems like the lower power electronic boards wouldn’t melt down like that and the LED’s probably wouldn’t all go out at once. I found some videos online showing how to take the rear cover off of the TV to reveal the boards and hoped I could see something that had burned out. I had to remove over 20 screws to get the cover off but didn’t see any damage.
