Model M/F components

I'm looking for the following Model-M/F components for the F65 project : - Wheelwriter code key - Non-stepped modifiers, preferably ISO but anything is useful for testing. - 2-part key stems - Housing stab inserts - 5.75u spacebar (7u still useful for testing) I'd also like to find a EU member with ...

Re: 65% Model F – Open Group Build

Measuring across 9 1u keys on my 5921 plate it seemed closer to 6" than 152mm Thanks for the graphic, good to know. I suspected my red option above might be the actual code key stem placement, isn't that what you're suggesting? L>R: 1.5u key, 1u key and 0.25u gap. Ignoring the code key doesn't make ...

Re: 65% Model F – Open Group Build

i think it is worth trying - make the bottom row pads slightly wide to accommodate as many different layouts as we can. We would need one more pin for a new column, though. Any suggestions as to what pin to use? And what pins to use for the TP option - with consideration for routing? Though i sugge...

Re: 65% Model F – Open Group Build

I can imagine most people would harvest components from a XT/5291 as it's the most common F board with the least desirable layout. Here's a parts list: XT/5291 ======= Provides: - 82 housings - ISO/ANSI alphanumeric keys except ]} key (can be substituted by numpad 1-9 for same color) - 12 1u grey ke...

Re: 65% Model F – Open Group Build

After realising that Model-M trackpoints don't actually go through the plate (no room on Model-F) I thought I'd investigate if it'd be an option for this project. This has nothing to do with the pad card so that's not a concern, the ribbon also conveniently goes to the right which is empty space in ...

Re: 65% Model F – Open Group Build

Let's compare the options Your suggestion (2): - The 5.75u spacebar pad interferes (I personally don't mind) - AFAIK a 3u key doesn't exist. I could attempt slicing my 9.75u spacebar to create one, but there'd be a visible seam. Ordering a quality 3dprinted one and casting it is an option, that's st...

Re: 65% Model F – Open Group Build

Right now, Enter plus back-slash are using 3 pads; Enter covers two pads, but only uses one (same) pad for sensing in ISO and ANSI config, the second for stabilization, and the third for back-slash - second and third swap depending on ISO or ANSI. Hypothetically, i could use the same column and row...

Re: 65% Model F – Open Group Build

Discovering this a little late, I'll ask a likely dumb question: could a 60% Model F build be Poker case compatible? There's many good ones out there in classy materials, and, uh, some of us happen to be 60% purists who find any immediately adjacent extra keys to be a recipe for fodsdyrt/ Not inter...

Re: 65% Model F – Open Group Build

Nice to see some interest :) https://i.imgur.com/yIv9ymp.png CAD screenshots, test print (PETG) pics: https://imgur.com/a/aLfioa9 The case design is done in FreeCAD and is mostly parametric and customizable. The top cover is a separate part, easy to edit and replace to change the look (or leave out ...

Re: Low profile Beamspring project

Finally, a resin cast low profile housing :) I poured the inner silicone mold and then cast a clear housing using a 3d-printed diagonal bar (which unsurprisingly broke). Given the leak issue during the previous casting attempt I used a LOT of vaseline and unfortunately some of it got on the slide ro...

Re: Low profile Beamspring project

Sorry about the lack of updates, there hasn't been a lot of progress. I'll hopefully pick up the pace when the workshop move is complete. I did however get some commonsense boards recently and started looking into the software and PCB side of things. Quite an impressive work, thank you for this and ...

Re: Xwhatsit/CS-Compatible IBM 3277 PCB

3. has anyone experimented with doing flexible capsense pcbs, so that you get a curved profile? this is really a question about the model f, but iirc its pcb was curved, and i was thinking it might make more sense to do a flexible pcb that rests on a curved surface, so that it gets that same curvat...

Re: Low profile Beamspring project

Can I ask what kind of program are you using? I have some switches to design too. As photekq pointed out I'm using FreeCAD, an open source cross-platform parametric solid modeler. It's similar to commercial alternatives but there are definitely limitations and annoyances as vvp pointed out. It is r...

Re: Low profile Beamspring project

A long overdue update... Repo update: - Toolpath examples - Housing lid added to assembly Capplate mold I've done two test casts using my existing mold: First: 2ml resin and 4g iron powder. There was an air pocket in a corner, I cut a separate injection channel in the opposite corner for the next at...

Re: Low profile Beamspring project

A very delayed update: I milled the plate as planned with a minor adjustment; I separated the diagonal "spring catcher bar" cavity part, attaching from the rear with an M2 screw (orange part in pictures). It allows me to experiment with dampened versions without affecting the plate, filing the tiny ...

Re: Low profile Beamspring project

Re: Low profile Beamspring project

Oh man, tell me this will be mass produced. I love the beamspring switches so much that after two days of using a model F 122 I had to go back to my 3101. Do you think your design will have important differences in feel? I would definitely build my endgame keyboard with them if not. I can relate to...

Re: Low profile Beamspring project

Did you cast resin? I am looking to get into that as my clear PLA 3d printed ones are not the best quality and obviously scratchy. I will be printing some in ABS this week and using acetone to smooth them out. I have never cast anything in resin and yours look super good. I would be interested in k...

Re: Low profile Beamspring project

The mount for the Selectric keycaps seems potentially fragile if it's going to be make of plastic. MX mount example you made seems super solid, though. Absolutely, I'll save those for casting. I fully expected the MX one to break during the abuse, I was surprised. Whoa! This is really cool and a ne...
