Been a bit quiet here. Lot of things were/ are happening.

The 90th video! Exciting.
For power converter testing, DC Bus supplied from 6x 24V 14A power supplies wired in series.
Awesome 🫣⚡️
Next we start looking at the W-VHS VCR, Panasonic NV-WV10.
Has some mechanical issues.
Look out for my 80th video. Coming soon.
Will be a multi part series trying to get this thing to work.
First Video about the Panasonic NV-WV10 W-VHS VCR is uploaded:

Episode 80! That is a lot.
Here is a video about 'fixing' an AV surround sound receiver amplifier that probably did not have anything wrong with it.
The boards did need a good cleaning.

I saw discussion about 'Sleep Sort'. An Interesting Idea.
Start a new thread for each element in an array, that sleeps for the value of the element then returns the value after the sleep. The elements are returned from sleep in order.
I implemented a Sleep Sort' / Wait Sort in LabVIEW trying to think of the most efficient single VI method of implementing it.
Here with a for loop with parallel iterations to create a sleep thread for every value in the input array.

Happy Holidays. Merry Christmas.
Let's look at a Sun Ultra 20 Workstation.
Complete with the sounds of a severe thunderstorm that started while I was looking for some Windows XP drivers.
Includes a peek at some D-VHS stuff.

Videos have been lacking lately. Been busy with work.
Now that is mostly over, for now. I can get back to Videos and VCR repairs.
Last bit of work was to length match the gate drive tracks.
Altium curved tracks are interesting and quite difficult to control.
DIN Rail Power Supply Teardown and brief investigation from recent live stream: youtu.be/PZ3v-qSZ2Tk
Is this a feature or a bug in @altium designer?
I want to click and drag on a capacitor, but other unrelated objects move with it.
When dragging components other things that move with it seem to be randomly chosen.
If I wanted to move multiple objects, I would select them first.
I made a video on looking inside Professional Video Monitors: EW0049 youtu.be/IjcI6g3TxpQ
Sony LMD-9020
Ikegami HLM-910R
Panasonic BT-LH900A
There has been an exciting development for the Sony one that did not work: EW0074 - Sony LMD-9020 Repaired youtu.be/ud8yDPVcuwM
Exciting things ahead!
We are entering the golden age of VHS. Where everything is an ugly gold color.
Panasonic NV-WV10.
W-VHS Analog High Definition VCR.
Apparently I was not supposed to rearrange the PWM lines to make the PCB layout easier.
Now I have to do this 😩
Make some special untangling cables.
First one was a bit messy, next is much nicer.
