Sherwood UC projector

Sherwood UC has two video projectors. One at the front for the congregation to see and one at the back for the minister etal to see. 

Many years ago, Tim S built a box to control them. Recently it had all stopped working. 

Tim called to ask if I would help. 

I was very happy to go to his place to look at the box. 

Eventually we decided we needed to go to the church to see if there was a problem there. That was an emotional baggage trigger for me. Went anyway. 

First off located a broken wire in a D9 gender bender. Wow isn't that a now un pc term.

Fixed that by soldering a new plug on the wire that had the wrong gender plug. However I still could not control the rear projector.  

Today Friday 31 March, 

We temporarily installed a new D9 cable. Initially that did not work. I was following the projector manual that said the comms was at 38400bps.  I thought I'd try 9600 and it worked. 

In the end the issue was, Tim had thought there was a issue with his box and had changed the CPU chip and installed a program that followed the documentation AND the documentation was wrong AND there had been a broken wire.

Feeling down / depressed is not something I like. 

It does feel like I have to focus hard when I feel myself going down. 

Inadequacy & rejection seem to lurk in my thoughts.

I've had someone say to me "you are only depressed because you choose to be" at the time I thought you arrogant bitch! F#ck you! My current thinking is there is a thinking component to it. I'm modelling it as a flywheel spinning on its axis. One way is happy and the other is sad. Stuff happens that kicks the wheel along.   If it's spinning in the happyness direction then sh%te might slow it a bit but moment keeps it spinning.   If it's spinning in the sad direction then any bit of bad stuff just kicks it along and it's hard to stop it and get it to spin in the happy direction. The other difficulty is if it's stationary then it doesn't take much to spin it one way or the other. Not sure if it's a perfect analogy but an interesting thought. 

 

Listening on spotify to Episode 307:The science of Emotional Intelligence | Daniel Goleman :

Mindfulness can be likened to physical exercise.  The more you repeat an exercise, the stronger or fitter you get.  The parallel as I get t, the more you think about certain things or in a certain way, then the more that thought process gets stronger.    

When does the photo of a black cat become a silhouette ?

at 16:00 they discuss teaching emotional intelligence.  How much better kids with emotional intelligence do in life.

Breath Exercise @28 minute mark
Shifts from fight or flight mode to relaxed

From Yoga -> Deep breath.  Hold as long as comfortable.  Exhale slowly.  Take another.  Do 6 times

Flat Battery - Captiva

 Seems 'tis the season for flat batteries.  This morning as I got in my car I put my foot on the brake and thought that it was odd that the brake lights did not light up the carport.  It was however 4am and so I put it down to another craptiva idiosyncrasy.  All was made clear though when I turned the key and the starter motor groaned.  Slowly turned the engine which luckily fired and off I drove to rowing. 

Arrived west end to over hear another guy had a flat battery in a merc of all things. Then one of our eights had a flat cox box. 

After rowing, the starter motor again did its best under arduous conditions.  I figured I'd better leave it running while I bought a coffee.  Didn't want to  tempt fate. 

 
I then plugged in my ODB2 doodad and had a look on the app on the phone.   While driving it was only 14V whereas I'd expected more like 16.  All was revealed when the engine was switched off.  I do note that I need to set a base line for my 0-100.  Just need to find a quiet suburban St with no red light cameras.

Baseline - New battery and engine on

Sunday 26 March 2023

Hmmm let me think.

Woke early as usual. 

Washed sheets. 

Filled tiida with petrol. 

Worked on the security cameras. 

7:30 coached at centenary. 

Then collected Cybele and drove her to my place so she could grab the tiida. 

Tinkered a bit more with cameras. 

Went into work.  Fixed the angelantoni thermal chamber. 

6-8 Did a social dancing lesson

feeling down

I'm a moody bugga. I don't like feeling down. I don't want to feel down. But right now I do feel down. Sagged. Heavy. Alone.  

I guess no one to share with contributes.  Both in personal life and work situation. Board?

The brain churns. Going over and over stuff. That doesn't help because one needs calmness to make good decisions. 

I feel overwhelmed at work.  

It feels like people are getting fixated on little details and coming to me and deluging me in them. 

A part number numbering issue.

A safety issue about doing personal stuff on ones own after hours.

The blue chamber faulty

Windows 11 Issues on my Lenovo

 1.  A dirty great ad for X-Box come up each time I boot.

2.  The CPU churns away and basically locks up on what I think is a windows search indexer.

 

I note in the "Processes" that Xbox(3) is present. 

And under Start>Apps there are two Xbox things

 

So under Start>Apps,
Right click Xbox Game Bar and selected uninstall

Right click Xbox and choose uninstall

 We also see various Xbox entries under Settings>Apps>Default Apps

Dancing

Went and did a social dancing class. Bruce's wife Wanda invited me. She'd tried the last few weekends but I've been busy at work. 

6-8:30 at DFO Jindalee

It's gonna take a lot of practice!

movie "Flirting"

https://youtu.be/x8hU_BMzgwM

 

Australian set in 1960 ish. 

Near Ballarat (I think)

Boys and girls boarding school on opposite sides of a lake. 

Interesting character study.

The boy who gets the girl is not the Captain of the footie team. He's a arty kid into history and poetry.

Most of the focus is on the boys and their interactions.

A few scenes looking at girl interaction 

The girls dress up for a dance. As they pull their dresses over their underwear, their eyes linger on each other. Checking each other out. More so than I think boys would of the other boys. 

Right at the end, two girls hug and say good by to the Ugandan girl with tears in their eyes. Two 

other girls look on. 

The classic scene of boys peaking through a hole in the wall watching the girls get changed. This is more of a boys scene because one of the "alpha" boys takes a photo and the main character intervenes. This results in a punch up. An interesting comment on where the line between OK (boys being boys) and being creepy and these days seen as stalking bordering on bullying / sexting was recognised even in the 1960's. 

My recollection on the way the movie was shot is that for the first 90% of the movie, most of the footage is framed fairly close.  To me this reflects the teenage world where teens live in a small self focused world.  For example, The footie match at the beginning is filed close.  All the action takes place in boarding house.  No school perspective.

At the end, the coming of age is reflected in the movie showing lots of world news big picture stuff.

 

RS232 Sniffer

 I made a circuit that lets me monitor an RS232 circuit.

 

CIRCUIT DESCRIPTION

First remember that in a RS232 circuit, the idle or "1" state is -12V
And it goes to +12V to transmit a zero.  This means that TX1, TX2 and TXMON are all mostly at -12V.

D1 and D2 create a -12V line.  Note one could add another diode from TXMON.
This is stored on C1 100u 35V Electrolytic.  Diodes Schottky 1N5817

R1, R2, R3 (all 4k7) hold the receive lines RX1 RX2 and RXMON at a -12V idle state.

If either of the TX lines TX1 or TX2 starts to transmit, then it will go to +12V and push RX MON to +12V through D5 or D6.

As shown the MON port can talk to port 2 (ie RX2).  So via D7 it can force RX2 to +12V.

If you want to transmit from the monitor to port 1, then put a diode from TXMON to RX1

Cast to Multiple Displays

Can I cast to multiple displays simultaneously?

Options

LAN connected.
Microsoft Display Adapter

LAN CONNECTION
I have a HiSense 55inch TV with an ethernet connection. 
From Win 11, Win-K When I try to cast to it, windows sees the TV but after a  delay of about a minute it says "Cant connect"

Apparently so but I've not tried it.

 

Cut out Cyst

On the weekend, the cyst started to swell up. Monday I contacted the plastic surgeon's nurse and she arranged an appointment Wednesday 10am. He had a look and suggested two options.

1. Disinfect, wait a couple of weeks too heal, come back and cut out the "capsule".

2. Do surgery now. 

I was advised that Option 2 came with a higher risk but figured that option 1 comes with 2 visits anyway and yet taking option 2 could mean a quicker fix and only one visit. 

The surgery was booked for 4pm that afternoon.  

I initially
