Model F problem
« on: Mon, 04 August 2014, 09:17:57 »
I have two terminal Model F's, and it seems my backup is experiencing a curious issue. My right arrow is registering as both, the right arrow and Numpad 4, resulting in the number 4 being displayed followed by a cursor movement to the right when actuated. Aqua Key Test confirms that it's registering both keys. HID listen displays the following when the right arrow is actuated:

r6B +5C d5C r6A +4F d4F
rF0 r6B -5C u5C rF0 r6A -4F u4F

I've already tried re-seating the key cap multiple times to no avail. I then tried to remap the right arrow to, well, the right arrow, but I don't know how to un-assign Numpad 4 to it.

Any ideas?

Next thing I would do is open it up and clean it.

Though if you're using Soarer's stuff and you don't use the numpad I believe you can map a key to nul.

I'll try that for the heck of it.

Okay that worked, which sucks because I actually do use the Numpad from time to time. Thanks for the suggestion, by the way.

Odd that it should manifest in the 4 and not the 1.

Could you have debris floating around in the underworld?

"Starting in 2011, the deficits again started to shrink. During Obama’s term  the deficit was reduced by $900 Billion  before finally in 2015 the GOP managed to wrangle a “reconciliation” bill out of Obama where he again cut corporate taxes, as well as made permanent some of George W. Bush’s original tax cuts. This is the year everything reversed. Before this, under Clinton, Bush and Obama the deficit in almost every year was gradually decreasing. The balance we had of taxes and the economy was bringing the deficit down, the money coming in was slowly catching up with the money going out until 2015. Trump’s subsequent tax cut has continued the new trend even after the rest of Bush’s cuts have since expired. Obama had an average GDP of 2.3%, with 11.6 million jobs created and unemployment peaking at 10% in 2009, then falling to 4.3% in 2016. If we had continued on that downward deficit track, we would have again reached balance and another surplus in 2017-2018.

Quite possibly, as this is the Model F I performed the ANSI mod on.

By the way, what's the best way to clean the PCB? Damp cloth? No alcohol, I assume.

UPDATE:

Okay, so the problem turned out to be that I had both, my F-122 and AEK plugged in simultaneously. Once I unplugged the AEK, the F-122's key registration issues resolved themselves.

It has been my experience that a Teensy does not play well with others, and that only one Teensy is allowed at a time.
