CHERRY G81 1800 HQU (MY) keyboard mechanical retrofit

Hi, lately I completed a mechanical retrofit to a CHERRY G81 1800 HQU rubberdome keyboard. This keyboard has nice double shot keycaps and I found a new and very cheap one on a local listing. The retrofit involved replacing the pcb with a G80 1800 Leeche (cina) one and adding a self designed/modified...

Re: How to improve MX Blacks?

Hi,
I like linears and I find that mx blacks are too heavy for my fingers too.

I usually replace them with lubed Gateron yellows as You can see here, where I replaced even the pcb in a g81. If You buy them from china they are extremely cheap.

Re: IBM 3101 Restoration and Cerakote

I remind You that, if you plan to install a controller, all metal parts must be in electrical contact with each other and grounded to the controller, especially the upper and lower plates or Your controller will read wrong and erratic capacitance from the key presses.

Re: New Compact Beamspring controller available

Hey guys! An update: It recently came to my attention that some 327x/3101 keyboards have assymetric card edge fingers, meaning the depth is different. This is a view from the bottom: 3276_assymetric_card_edge_connector.png So the rows side (the right side when you look from on top of the keyboard) ...

Re: Beamspring keycap yellowing

Hi,
I was asking myself the same question.
I've been given some 3276s to restore and some have one or two yellowed keycaps. I know how to retrobright but I'm afraid of bleaching the caps. Did anyone attempt a retrobright on those?

Re: Beamspring Factory process - How to

"The external coil springs are probably the last unsolved element at this time. "

Check Aliexpress, https://www.aliexpress.com/item/3296025 ... 4c4d90iFjC

Those are havier than the originals but better than none.

Re: UPDATED: IBM Model F restoration - May 2019

Great work!

And what a rust! I personally would have sprayed an antirust paint first on the plate as a prep to the final paint , but that's a matter of preference.

Thanks for the cross link to my Model F restoration video!!!

Hi,

great info. My insulation mat did look completely different (as did the PCB):

Is that mat a new one or just the one that came with your beamspring?

That cable is awesome, I hope you have a matching one for the usb.
I didn't find a matching one, instead, I'm waiting for a black sleeved 90 degr magnetic cable form china.
The Pro Micro micro-usb connector is too weak for normal use. I already broke one.
