Poor eMate needs fixing

[mmu_man]

I acquired a second eMate recently, and this one needs a bit more work than the previous one… First, it needs a good clean and has some rust in places…



I'll handle that later, first I had to fix that burnt zener diode that shorts the power input. Likely a protection diode (12V when the input is 7.5V), which served its office when some misinformed user send more than 12V into it.



The one I replaced it with probably can dissipate less but well… At least the short is gone. The power LED lights up green then orange, so there's some life.



More tomorrow.

That zener diode really took one for the team. How are the hinges?

Like new from factory, but I'll need to fix that

I got distracted because… because people

Today I cleaned up the bottom case on Dave's stream:

Still needs a lot of work, but I made sure it's working. Just the touch screen doesn't yet, but the screen ribbon needs more cleaning due to spillage.

Let's work on that some more on a live stream:

Working on another eMate

I got a second eMate, which has some corrosion and a burnt zener diode. Let's work on that some more.

So, one spring broke after I added the washer. I suppose that washer was a bit too large and so didn't push the spring inside the cavity properly… Or maybe it just needed more grease… I added a smaller washer under that one for good measure.
