Apple AEK frustrations etc
« on: Sat, 06 July 2013, 18:43:59 »
Although I am seen by some people out there as something special, I am really a neophyte in a lot of ways.

For example, until today, I had never soldered switches in a keyboard! I have had 2 AEKs sitting around, for quite a while, with a few dead switches waiting for repairs. One is beautiful and new-looking, and the other is nauseatingly ugly and yellowed. Naturally, I wanted to salvage the pretty one.

However, I found that it had many bad switches, and dead "areas" of multiple switches. Looking at the back, I could see corrosion and deterioration.

So, on to the other one. I saw 4 bad switches, so I took 4 out of the pretty one and Presto! it worked.

Although it took a while to wrestle the old ones out with my cheap-ass soldering gear, it wasn't really too bad.

Aqua Test showed that they all worked, but then also identified F8 as bad. So, I swapped that one, too.

Unfortunately, probably due to some sort of heavy-handedness on my part, a small section (2mm square) of the printed circuit peeled up at one of the legs. Now, not only was the new F8 dead, but it took out the first half of the number row along with it.

Scheisse + Merde

So, clearly, since I care a lot more about orange Alps switches than I do about Apple keyboards, I suppose that I will harvest what I can from both boards and hold them for a future project, now that there are some juicy ones appearing. And I do have a couple of Dell AT101s that I could transplant them into.

PS - the old AEK was serial number approx 200K and the new one was approx 600K, and the spacebar stabilizers were different and incompatible. I spent some time trying to put the pretty one on until I realized that. everything else seemed almost identical. both boards had the same model numbers and were made in USA.

Citizens United violates the essence of what made America a great country in its political system. Now it’s just an oligarchy, with unlimited political bribery being the essence of getting the nominations for president or to elect the president.
So now we’ve just seen a complete subversion of our political system as a payoff to major contributors, who want and expect and sometimes get favors for themselves after the election’s over.”

You can probably replace the broken trace with a wire.

BTW.. Different space bars. are the FCC IDs of the keyboards identical?

You can probably repair it, It's likely just a broken trace, you can solder to the trace after scraping off some soldermask, or jumper it, ignoring the trace completely.

Still, it might be a better use of the switches to be housed in an AT101. Up to you of course.

If you want me to look at fixing it, I'd gladly do it, if you want to ship it to me.

I may be near a Radio Shack tomorrow, I will by some of that conductive paint stuff and see if it works.

Chucking the switches into an AT101 would probably make for an easier-to-interface device in the long run.

From two boards, even with a few dead switches, you should have enough leftovers to make an Alps-switched ergodox clone (after all, it only requires redesigning the mounting and PCB :)
