20190813flowers offered.jpg

On August 13 when we visited the grave to offer floweres we found new flowers were already offered with a can of beer. They were offered by two of the old intimate friends of Tomohiro as they came back home during the Bon. I could meet one of them the next evening accidentally and knew the offerings were done by them. Thank you for the offerings.

The LCD monitor which is built in the new fpga FM tuner told me the receiving condition of FM radio wave is very bad. In order to clean the receiving wave I made a dedicated filter for 82.5MHz. Please visit here for details.

An HB9CV Dedicated To NHK-FM On 82.5MHz.
(Installed on 2019/08/12, No.207)

installed on the mast.jpg

I built a new antenna in order to improve gain and directivity. It has replaced the old dipole mounted at the lowest posidion on the mast shown in the photo. The antenna added stabilty to the superb sound of the FPGA tuner. The LCD monitor which is built in the new fpga FM tuner told me the receiving condition of FM radio wave from NHK-FM Nagoya is very bad. In order to clean the receiving wave I made a dedicated filter for 82.5MHz. Please visit here for details.

I've been building a new FM receiving antenna.

hb9cv for nhk fm halfmade.jpg

My new full digital fm-tuner has a monitor of the receiving radio wave and it has been suggesting me that I should improve the antenna for the better sound.
So, I started building a new HB9CV type antenna (photo above:half made). It's a two-element antenna which is more compact and efficient compared to a three-element yagi. hb9cv short bar components.jpg However, it's more complicated and has been taking me more time and devices (photo above:short bar components). How will it turn out?

I Trimmed The Hedges Around Our Family Tomb.

20190726hedges trimmed.jpg

The cooperative annual summer cleaning of the graveyard is scheduled on 28th of July for about an hour from 7 to 8 a.m. It's too short for me. So I finished trimming the hedges around our tomb today beforehand. That is, my job left on that day is weeding only. The trimming took about three hours in the fierce heat as it was last year.

Full Digital FM Tuner
(Installed on 2019/07/16 No.204)

full digital fm tuner/images/full digital fm tuner in use2.jpg

About a month ago my Trio KT-8300 FM tuner broke. It really wasn't but I judged so at that time. While surfing for a new tuner I came upon a fpga FM tuner developed by Teruhiko Hayashi. I bought one from him and encased it in an old broken dvd player as shown in the photo above. Encasing wasn't smooth. Only with his kind advices, for which I'm greatly thankful, could I make it working. For details please visit here.

Restoring A Septic Tank Hatch.
(Installed on 2019/06/21, No.203)

back to its place.jpg

The cast iron hatch of our septic tank had dangerously corroded. I restored it as shown in the photo. The price of a new hatch, which was too expensive, decided me to restore it with the leftover FRP materials I had kept since the last speaker making. The hatch above looks wet but it's not. It only looks so with its polyester coating. For details click here.

An old co-worker of my ex-son rode his Harley-Davidson to pay a visit to our son's grave from Shizuoka. It took him about two hours. It was a best day for riding, which I hope he enjoyed.
I showed him my old BMW R100RS which I have only been keeping, not riding for over 20 years. We enjoyed a while talking about bikes. Thanks Mr. SK for visiting.

June 16 was my ex-son's 33rd birthday. His college classmates and an old friend visited his grave and offered beautiful flowers.
After visiting the grave the classmates spent a few hours before the altar remembering with us the days they shared with him.
We missed the old friend who separately visited the grave.
We thank them all for visiting the grave and offering the beautiful flowers.

A Screen Door Installed
(Installed on 2019/06/07, No.199)

nob pocket outside.jpg

I installed a screen door to the door of the shed of which I restored the termite damage before. We had used an old screen door which was wider than the shed door only to keep out homeless cats as well as to keep in our cats which we had kept in the shed.
I reformed this old screen door to fit to the shed door. However the screen door I reformed was for a sliding door. I hadn't realized that a hinged door had a nob and a screen door for a sliding door couldn't be used as it was. In order to solve the problem I installed a nob pocket as shown in the photo. It took three days to finish the work! For details please visit here.

n-wall finished.jpg

I painted the northern wall of the garage/storage. The upper area was in better condition and so I painted the lower area only this time.
As I thought the wall was easier to paint I painted it lastly. However the rust damage was serious and the mending took longer.
The first photo shows the wall after I painted an anticorrosive. The second shows how the wall was finished with a polycarbonate backing. I hope the painting with the mending lasts longer.

I've been still painting (getting close to the end). I had the photo taken while I was painting the southern wall of the garage/storage. The solar water heater which I painted last week is showing on the roof.
It had been left unattended too long time that I found some parts of which seriously rusted out. I removed the rust and painted neatly for the time being. Working on the roof tires me a lot for the sake of oxygen shortage(..never!).

20190426painting.jpg

I've been engaged in painting. Restoring termite damage awakened me to such maintenance work. Our house has several eaves and walls of galvanized iron and I found some parts of them are rusting. I have to check the cover of the heat exchanger of the solar heater installed on top of the garage roof, too.
I have been troubled a lot because some eaves are at the difficult places to paint but I have been conscientious in doing this maintenance work because it is very probable that this is the last opportunity.

Replacement of the connectors.
(Installed on 2019/04/21, No.193)

connector change finished.jpg

As malcontact had become more often and worse I replaced connectors of the speaker networks on the Nautilus D.I.Y. The photo shows the network boards with the new connectors mounted. They were the networks originally used on a Technics SB-7 System.
The boards are different in color betraying, I suppose, a situation of the subcontracted workshop in those days. I had once found very different sized condensers of the same capacity. For details please visit the page on my website.

The Termite Damage Restored
(Installed on 2019/04/03, No.191)

termite damage restored.jpg

In finishing the work I painted the galvanized iron sheet around the door anew and gave preservatives to the foot of pillars. I had been poor in measuring, and so I paid a very careful attention this time that I could fit the pillars and the beam just into their places. I engraved in mind never to let termite haunt and the shed become a dump.

Termite Damage!
(Installed on 2019/03/21, No.190)

20190309termite damage.jpg

I happened to find termite damage in the shed attached to the house. A shocking discovery it was!
The shed had been our kittens' place too. They died one after another recently. My wife had taken care of them and I seldom went there. For many years it had been used unattended.
The shed was full of things. I could take the photo only after we cleared the place! As the damage was invisible I broke the surfaces of pillars and a peam in order to expose it.
We are still sorting and disposing things. It seems to take some more days before I can start fixing.

(Installed on 2019/03/03, No.189)

While I was teaching at the college I worked at I escouted students a few times to the English Language Institute in the University of Britich Colombia in Canada.
The institute celebrates the 50th anniversary of its foundation this year. Suggested by my dear old member of ELI staff, I contributed my impact story which has been live now on the last page of Impact Stories
The following is a partial copy of the 'Impact Stories'. The snap photo was taken when I visited Vancouver in 1995 for the third time with my family. Many emotions crowd in on me.

Here is a partial copy from ELI50.

In the evening of Jan.16 my ex-son's college classmates paid visits to his grave. As usual, the married ones came with their families.
The visit was carried out because one of the classmates is expected to be transferred to Germany this spring and they'd find it difficult to get together for some time.
It was a chilly windy day. After visiting the grave we enjoyed sukiyaki together sharing a warm time talking about the days they spent with my ex-son.

giant cedar at sugihara2.jpg

I paid a visit to another big cedar. We drove far deep into mountains in Gifu. However, the place was within the city precincts of Seki. There were a few houses around the tree but we witnessed only one person while we stayed at the place.
Giant the tree was but it appealed its existence far larger than life. According to the information on the board it was 50 meters high and 3 meters across the trunk.
There was a warning to keep off the roped area to avoid the risk of beeing hit by a falling branch but it was a calm day and we ventured to get close to the trunk to touch and feel it.

Jan.30th was a warm, or rather hot windless day with the sun shining in the clear blue sky. It invited us to take for a drive with my wife to pay a visit to a big cedar.
The cedar was in the precincts of a shrine in Shiga Prefecture. It was about an hour drive. The tree was one at the base growing into three big trunks. We were alone there and we could enjoy watching and softly touching the tree without beeing bothered by other people.

source-amp-sp selector.jpg

I completed (so I thought) this selector five years ago but presently some malfunction started. I have fixed it (so I thought) but recently a stressful mulfunction started again.
The cause was my poor soldering. It happened because I had not been used to the new type of print board with a large copper-foil area. It dissipates a lot of heat and thus results in poor solderings.
Such mulfunctions turn up sometime later. Last time about two years ago I took off boards and did a big fix which was not perfect though.
The mulfunction this time was on a left channel and I could shoot the exact point of the trouble as shown in the photo.
source-amp-selector last fix.jpg

Incidentally the function of the selector is shown as in the bock chart below. You can select one set of equipment as you please out of five sources, three amps and two speaker systems. You can't find such a selector on the market.

Now that this fix is the last one I'm sure, the equipment sounds different to my ears.

Monet's pond
(Installed on 2019/01/15, No.182)
Intrigued by unusual warmth I went for a drive with my wife to pay a visit to a pond which has become so popular as to be nicknamed "Monet's Pond." It was about an hour drive to go into mountains.
Though very warm it was, the pond was, naturally, putting on winter clothes but people like us were continuosly visiting in twos and threes. The place would be much beautiful and worth visiting again in a warmer season we thought.
