This is the vegetarian version. A meat-lovers version would have modified the second last panel.

Fixing an electric toy train engine

I was asked to repair a toy train that was not working.

After checking the batteries for power with a multi-meter I guessed it was the motor and pulled it apart.

I cleaned the grease off the rotor and took some fresher grease, still black looking, from the contact points.

I spread the grease around the clean rotor and reassembled it.

It Worked!

Lap Top Power Socket

An Asus laptop had power problems.

I found a few videos.

Short summary

A long summary

I played the short video until I was confident then I counted all the screws.

I made a plan...



Battery 1

rubber feet 4

Screw under feet 4

one screw at back in battery area 1

Under cover 1

Underneath screws 11

small door 1

screws under door 2

battery area screws 5

Keyboard 1

Keyboard ribbon 2

Optical drive 1

screws in optical drive area 3

Under track pad 7

IO cable 1

Speaker cable 4

IO Board screw 1

IO board removal 1

Fix power plug

And gave it a go, taking a photo at every step.
Then I soldered up the broken part.

It was the gold solid wire coming out the rear of the socket!
Can you see the black break in the gold wire?

Then I loaded the photos onto my laptop and went through them in reverse.
Using the photos as a check procedure.

I had to watch a few segments of the long video in order to connect back in the ribbon cables.
That was the most difficult part. But my photos showed me the before connections, so I kept persevering until the ribbon cables looked the same.

No screws were lost or damaged in this processes!
And none left over. I used magnets to hold the screws.

Backup Strategies


My brother called me about my Dad's backups. While chatting about it I thought I may as well blog what I do.

When thinking about backups we think primarily about how we would restore those backups easily. So we aim to make it easy to restore backups.

Remember that if you use Google drive or a Cloud drive it means you must be connected to the Internet to recover the files.

What I do is write up my plan in a document. That way I have something to read in the pressure time of getting a backup back rather than tying to remember where I stored everything while under pressure.

I think through each data type I have. Then I think how to back it up and how to restore it.

I do not tend to make copies of the whole computer, except the Mac, I just copy the important data from the computer. If a computer is broken I will use an alternate computer or rebuild one depending on the needs at the time.

For me these are the devices I look for data to back up:
My Mac lap top
My Windows Lap top (Several data types.)
My Windows desk top machine (Mainly photos)
And others...

My basic approach is to have a primary, or 'in use' copy of my data. And have a single location for each type as a backup.

Here is a template of what I think about:

Data Set Name: 
Size in GB or MB:
Original location:
Backup Location:
Logic of placing the backup there:
Any program used to copy over the backup:
Any issues to be aware of:

Here is an example:
Size: Whole Mac Book
Originals: On the Mac
Backup Location: on the 500GB external Time Machine drive
Logic:  Easy to do and secure as the 500GB drive stays home
Program used: Time Machine to back it up and Time Machine to recover it
Issues: None

Lilypond files
Size: About 877KB
Originals: 1TB External drive E:\Graham\Music\1 Songs by Graham Okely\
Backup Location: Black Kingston 8 GB USB
Logic: Copy only .ly files to the black Kingston USB.
Program used: PowerShell:
E:\Graham\Music\4 Music Resources and Songs by Graham Okely\BackupLilypond.ps1
Copy-Item -Path "E:\Graham\Music\1 Songs by Graham Okely\" -Filter *.ly  -Destination F:\Music -Recurse
Copy files back manually.

Issues: No Worries copied over ok.

Web site programs
Size in GB or MB : about 28MB
Original location: Windows Lap Top
Backup Location: Google Drive
Logic of placing the backup there:  Easy to copy to and from
Any program used to backup: Windows Explorer
Any issues to be aware of: Internet must be working to recover files.

To recover a backup I go to that location and copy the files back.

So there you are backups and restores made easy. I review the backup document when I think it is required.

I tend not to automate backups as it is best to see it working and see any error messages first hand.

Keep making backups simple and make sure you can recover your backups.

Consider the security of your backups!

Monthly Blessing

Strength, God give you strength to do the things he has called you to do. To love, to live, to be there for your family, friends and fellowship. Energy to get up and get going, to think right. God give you power to make the choice that brings life. Dunamus power to break through those things that are keeping you back and out of the blessing of God. The blessing of the Lord makes you rich and he adds no sorrow with it. (Proverbs 10:22)

God bless you.
