Slow-ish Movie Player

I seek the Grail.

Have you met Eye-gor ?

When I added the IT8951 code to the SlowMovie Python I commented out this line, with the intention of adding it back...

#epd.sleep()

What happened? The display was not entering deep sleep which appears to have caused an early failure :(

New sleep line: 

display.epd.sleep()

Now that the display sleeps correctly, I required the "init" line which I had also removed... 

#epd.init()

 Adding the "run" command seems to work:

display.epd.run()

If anyone knows technically why sleep is required, feel free to comment below! I'm assuming this has to do with the constant charging of the particles that separately create the black and white image, and a constant charge must wear them out?

I reversed the direction of the fan I installed to blow over the Pi rather than draw from it. So far has been over 48 hours and no freezing.

The Pi

Kubrick ?

I added the heat sinks to most of the larger silicon and now have a fan drawing air over them but have still experienced the screen failing to update.

Pressing the reset button on the Waveshare hat puts the screen back into an operating state. The Pi script is still running, so on the next image push the screen updates like normal.

It's hard to believe the issue is heat anymore because it's not getting much beyond warm, if that.

So it turns out the Raspberry Pi Waveshare hat does not like being stuck in a box :)

After some hours the Pi script is still running but the Waveshare hat seems to have stopped updating the screen.

If I leave the back open and some room around the controller it is stable. I'll need to add some passive cooling to the Pi and vent the rear door of the frame.

The frame is deep enough to house the Raspberry Pi and stand on its own. There is a door that sits flush with the backing and lets me run a power cable out the back.

There is enough room for a fairly large battery, and I'm sure it's possible to put the Pi to sleep and only wake up to run the job and update the screen. Then I could ditch the power adapter.

Can you guess the movie?
