Re: ESSK - Enhanced FSSK PCB.

Not sure why you'd want 10 keyboards for yourself.. Make that 9 if these work as drop in replacements inside an FSSK. I'd gladly take one if it can be the cherry on top of my TS project. ;) Actually, that is what i was thinking; order 10, one or two for DMA, one for myself, and offer the rest capac...

Re: ESSK - Enhanced FSSK PCB.

I have been away from Deskthority for about a year and decided to visit today. Great to hear that the Triomate works. Do you think this would work on a 0.4 mm board? I think i would be up for paying for a batch of 10 ESSK size if you would not mind making the controllers. Oh yeah. I moved to Ohio. G...

Re: Beam Spring 104+SSK Reproduction Project! First Batch In Stock, Shipping early next year after New Model F Project

i'm surprised that no one suggested "unsaver + numpad" to address the 8x16 controller limitation. sure, you would be paying for two cases and controllers, but it also (a) make folks that might prefer an unsaver happy, and (2) would allow folks to mix it up (F unsaver + beam tenkey), and (iii) allow ...

Re: FSSK PCBs (1st round)

I ordered the new SSK and it is nice ... except for that annoying thing with the Q key (which i hear they have a firmware fix for). I promptly ripped off the tenons (melted plastic studs) to look at the membranes and LEDs. I worked up a 16 x 6 matrix that is elegantly simple. The only issue is/was t...

Re: Unicomp retired black 104/105 Classic models + latest on the Mini M SSK

Converting a Mini M to Mini F will be more complicated than i hoped. The new barrel frame has four obstructions that block 8 keys. The three blockages covering CV, NM, and <> are there to support and stiffen the space bar stabilizers. They can probably be removed with careful use of a razor (less th...

Re: Unicomp retired black 104/105 Classic models + latest on the Mini M SSK

it would be pretty simple to design a custom controller. I will be doing that for my F conversion, but "capacitance sensing" so not an appropriate fit for membranes.

Re: Unicomp retired black 104/105 Classic models + latest on the Mini M SSK

I had the "feature" where Q doesn't register. It is not my most commonly used key, but i would have wanted it fixed if i had not already decided that i would be cracking it open to get to the matrix. Still, i would think that Unicomp should have found that bug before shipping. The 16 x 12 matrix is ...

iDollar designed a PCB for F conversion several years ago, but I thought there was room for some improvement. My biggest criticism of his design was trace routing; specifically traces too close to other traces, pads, and tenon holes. Much of these issues were due to matrix and controller choice. Eig...

You can go onto Etsy and search for "EVA costume". Most of what you get will be for laser patterns - but you can PM them and ask who they recommend for materials and service.

Most "art foam" is in fact EVA. It is used a lot in cosplay circles because it is (often) colorful and easy to work with. It is sometimes a bit stiff for model F foam, but it worked for me.

Re: (Model MF) Remodeling the Model M (aka.. the Mara)

A basic principal of capacitive and contact keyboard matrix design; rows and columns should intersect exactly once. If they intersect more than once, you will have two switches that produce the same result (at best) or two that do nothing (at worst). Your 121 key matrix will likely be 6 by 21 or 22....

Re: (Model MF) Remodeling the Model M (aka.. the Mara)

Very little sound is generated by the flipper. Most comes from the spring smacking the inside of the barrel when it buckles - with secondary coming from vibration of the spring itself. Changing the spring will have the biggest impact on sound. I think Ellipse reported this too.
