A friend met up with me to go try the new ramen place that is in Uwajimaya. We have high hope that it serves half-decent bowls of ramen. I have to admit I am very hard to please and I have yet to be impressed by any that I tried in this country. The decor and presentation of the restaurant looks right, and so is the menu. Usually if the place try to be everything of Japanese it is a sign to avoid. You want to see they serve nothing else but ramen and Gyoza, and drinks.

I have been evaluating this NVR security camera system for 10 days now. While I jumped from the initial cash outlay of $250 to $1000 I have no disillusions that this is nothing like the systems used in commercial applications. Then there is law enforcement equipment that a camera alone cost a few thousand dollars. I think I have a well informed level of expectation of what to expect. I am very glad that I opted to spend a bit more. The network based NVR is the way to go for the ease of camera installation if you want to maintain unobtrusive professional installation.

Hummingbird feeders are some of the worst ripoffs of consumer goods. Most are very poorly design and made. The prices for one of this cheap plastic thing that cost may be $0.30 sold for 50 folds. I never want to pay over $5 each. The secret is to way for autumn when the stores are making room for Christmas merchandise.

Looking back it has been a while since I ate pig stomach. While shopping in my regular Asian grocery stores I was disappointed at the lack of selections of live seafood. This year the Pacific Northwest crab and other shellfishes harvest must be abnormally low. I came across the nice looking pig stomachs. They were 2 in a pack so I bought a pack.

It was only in 2014 my Windows desktop computer went kaputt. I managed to diagnosed to the system power supply, or as I thought but the root cause was not entirely clear even though I managed to repaired it. I swapped out the power supply with another PC that has an identical unit. Strangely the donor PC works just fine with the "bad" power supply. That left me wonder if the power supply as after all not the cause of the failure. Fast forward to a few weeks ago, my same Windows computer died all a sudden while resuming from sleep.

It has been nearly a year since I decided to buy a 4-stroke leave blower against the common wisdom. Upon first receiving it I was very pleased with its performance, and especially how quiet it is. Even at full throttle I find it no need to wear any hearing protection. The other benefits are the cleaner exhaust and without having to deal with gasoline and oil mixture. I was also very impressed on how little fuel it consumes - until a few months into the ownership.

I managed to maintained the upholstery in Isolde in pristine condition after 27 years. The secret is a layer of sacrificial material over the factory fabric. In recent years the fabric on the bed cover deteriorated and I have been challenged as what to do. The cover is a old fashion sleeping bag that has been modified in circa 26 years ago. Today these old fashion sleeping bags are few and far in between. I entertained replacing the worn fabric while keeping the insulation core of the sleeping bag. The problem is the retail cost of the fabric would cost more than the sleeping bag.

As in any design development, there are challenges with the parts that one specified. I happened upon the DHT11 temperature and humidity sensor because of its dual function. It would turn out it was fun while the curiosity lasted. I have 3 of this and found that they are worthless junk. The temperature reading often jumps around 2 degrees, and at time 8 in consecutive samples. Also all three are extremely inaccurate. I had play with the Maxim DS18B20 quite early on and found them to be very accurate for solid state active sensor. One reason reason that I didn't choose it was my attracted to the DHT11's humidity capability. The bigger reason is the library for the DS18B20 is very memory intensive, and I had ran out of program memory as well as SRAM.

Recently I have been into making Japanese rolled omelette. Actually more like my interpretation of this omelette technique. I am inspired by how Japanese would take foreign dishes and turn them into their own versions of Western dishes but suit their taste.

I added a clock and calendar screen. It took a bit of work to sort out the navigation logic since this is a new feature that I didn't plan for. With each feature that I add, it had been a hand-to-hand combat to conserve precious memory, both the flash and the static RAM. The latter is most critical as there is only 2k bytes. My goal is to have a least uncommitted 512 bytes left. The power management features that I implemented is working very well now and appears to have few bugs. The joystick UI is very smooth without mis-registration. I also managed to add time stamps to the file creation and modified.
