Model MF - GB CLOSED

Pick our controller... Voting ends on Friday

The mini-xWhatsit that WCass shrunk down. It uses the same mini-controller design as Ellipse's F62/77, but with a connector meant to slip onto our PCB (inverted running parallel to the backplate)

31%
The CommonSense that DMA has recently put together. This is young yet, but has the most long term promise (not a question). It will have a very similar connector (possibly perpendicular vs. parallel slip-on mount)

@lot_lizard: I haven't checked this thread in quite a while. Looking at the recent posts about the springs has me somewhat confused about the goal and where you are now regarding the weight, sound, and feel of the switches. What I would hope for in the MF SSK and MF full-size is something very similar to the weight, sound, and feel of the switches in my XT board.

Can we do a split, let's say F-row worth of 45g ones, for academic purposes?

Sure... I can just throw some of the 40-45g in with the others so you can play around with them. Disclaimer... they are nuts light. I land back home later this evening, and we will be back to having some progress

I'm feeling a degree of nervousness about the 55g springs: I quite like my M's usual 60-80 or wherever they're at as I'm not a touch typist, I like resting my fingers on the keys and I like the nice loud clattery noise! If I'll still get all those things then that's fine, but I'm hoping they won't make the keyboard feel much more "trigger happy" and quiet.

The replacement springs were an experiment. We decided since we were making completely new ones altogether, that we would try lighter tensions (50-55g vs. 60-65g of stock Fs) because no one knew what the result would be. I undershot the math, and they came in at 40-45g. I have since ordered new ones that will come in at 50-55g and 60-65g now that we truly know what the result will be by playing with the spring characteristics. All in the name of !!science!!


Everyone will get the original goal of 50-55g unless you send me a PM stating otherwise. I will throw in a small number of 40-45g just so you can get an idea of the difference. To be honest, you (everyone) might like more than you are expecting. It's an intriguing but unique result. I actually think that 50-55g will be a "sweet spot"

This may have been answered previously, but in case the lighter weighted springs turn out generally preferred by the community, will it be possible to run a spring-and-hammer-assemblies GB for people who might wish to upgrade their Model Fs?

Since I know how these will turn out, I ordered the 50-55g in proper bulk. There won't be any future runs because it is so expensive to have springs produced (even 1). I ordered 40k of the 50-55g to drive the price per down, so we should be covered from here on out (or at least a VERY long time). They will be for sale on mfDrop.com going forward (not up yet). They won't be as cheap as they were here, but the prices on the ecomm site will always be "cheap".


The goal of this LLC will always be break even. Any funding we raise will go directly into the hobby somehow so I can net essentially zero with it on taxes. We might actually be better off being a true "non-profit" in regards to taxes (501c3), but that is a slippery slope. We could donate boards to the community, make charitable donations to other non-profits, etc... but that is more bookkeeping than I want to fart with. For a while at least, we will be a "business" that claims an EBITDA of $0.00

ooh... I like that. Where were you 3 weeks ago with that idea? ;)

I liked "barrel spring" (first choice), but the .com was taken. "Spring and barrel" is there (I hate typing "and" in a url though). Your hammer bit reminds me of hammermade. For those that don't know... This IS one of the great up and comers.

Well, of course, the Spring&Hammer thing this was a crude attempt to mimic the classic "Arm&&Hammer" brand (so named by the company founder, Armand Hammer).

I usually prefer writing out "and" as well, but the original used the ampersand symbol.

Careful with that. IRS may come to you after 3 years, say "it's hobby, man!" and tax all your expenses. I somehow think you know this already, but still - that's a thing to watch out for.

As far as non-profits go.. 501(d) is the way. Church of The Holy Spring!

I agree to this... I've been lazy. Apologize...


I have had and will have a horrid work schedule for another couple of weeks. We have some "surprise acquisitions" that I am accountable for that require travel. I did finally get my beamsprings out to DMA (will PM you a tracking number), and a few miscellaneous PCBs. The perfect storm of "anti-progress" from my end. Attempting to keep the boulder moving, but certainly lack luster for me

LLC. Hmm. For now XMIT Keyboards is a sole proprietorship. I've always said "keyboards first, politics later". I really should spend some time at some point talking to a lawyer about possible business entities but I'm too much of an anti-authoritatian hacker to really give a shit or take it seriously. People are getting keyboards they love, that's all that matters to me for now. So good luck with all of that.

It would be well worth $100 for a consultation to keep yourself out of trouble, but I never had the impression that you are raking in a huge amount of money there.

The MF project, on the other hand, say at least 200+ kits @ $200+ each, that multiplies out to some serious money.

Couple of updates... neither overly pleasant to report. I checked with our foam producer, and they are still attempting to produce the die for stabilizers that wrap each of the barrels. I told them we needed progress by the end of the month, but of all our producers (we have several), we have the weakest ties to them and are "low volume". I will make some proper threats if I don't see some pictures of a roll die soon. We can certainly move to another entity based on commitments.

The boxes are produced (die is complete, boards are struck), but they are waiting on a printing plate to arrive. My fault, but I wanted to make these feel a little nicer by having a logo. That appears to have caused a 1-2 week delay in finalizing our packaging.

I am traveling again for work (will be again for the next week, possibly 2), but have both prototype boards with me. I have been pounding on them in the evenings, and things seem to be working quite well. When I return, I will have the plates go into production I think (it's time... no foreseeable issues).

All that remains then is the electronics (controller and PCB). The controller seems to be doing very well. I am not a BLAZING typist, but churn around 90-100 wpm consistently, and I haven't seen hiccups. This split spacebar is taking me a bit to get used to though. I like it, but it's very light compared to the normal 7u. I have a couple of changes that I still need to document and send to WCass regarding pass-through hole placement and "branding", and then we will send those off. Eventually we need to decide on the controller front what to do. I didn't help matters by sending DMA the beamsprings later than I had hoped, but eventually we will need to vote. Worst case, we move forward with this to have something in hand and have another buy later if CommonSense proves out on the MF as well. I have quite a bit of faith in DMA's work though, and don't want to be hasty.

We are getting closer. My work schedule for travel has been HORRID and for that I apologize, but we are at least in the "field goal range" if you follow American Football. If we would have been clairvoyant, we could have waited 1-2 months for the GB, but if we took that strategy... we would never pull the trigger in the first place.

Great update, lot_lizard. Thanks as always for keeping us informed. It's too bad about the foam supplier. I hope they get everything going soon. The delay in the packaging doesn't seem a problem to me, since we haven't even started electronics production yet.

I hope we can get an update from DMA here. I'd like to know where CommonSense development stands in relation to this project (form factor, USB daughter card compatibility, etc.)

..since you asked..
QFN chips are sitting at my table, PCBs are supposed to be delivered tomorrow.
Just got my hot air gun from the mailbox and used it to desolder my first attempt at SMD soldering (placed the chip 180 degrees to proper position :) ).

So over the weekend I should know if the hardware is ready.

1x1 winkeys with only one each side looks so amazing

unicomp should have done it like that from the start.

So are you going to hack away the spacers?

WKL +winkeys is the best way to lay out winkeys.

We can only hope. Unicomp needs to see the light on better dyesub methods as well, I bought 4 of those diamond caps and 2 were terribly misaligned. These arent perfect either, but are the best of 4.

Yeah, I am. 1.5u mods with 1u winkeys is the best layout ever. it looks SO GOOD compared to the asymmetrical fuckup that is 1.25u mods with 6.25u spacebar. It should be easy to cut the blockers out of the case, and this case is in pretty banged up condition, so we won't be losing a good case.

Mmmkay, I've managed not to burn the chip with me mighty air gun!

Compiled and uploaded firmware, key monitor shows something - but what it shows and how usable it is - I'll only know tomorrow. Or, technically, "later today", because it's 00:17 already.
Stay tuned!

Update: found a mistake in PCB tracing, greenwired it (man those 0.4mm pitch tracks are hard to solder!), found that I removed too much bypass caps - greenwired those too. Works like a charm!
Will make final prototype PCB in a couple of days and send to oshpark.

Software seems harder than it seemed 2 weeks ago - those macros are quite hard to get right, especially at 1000CPS. You need to actually delay key releases to make sure system will see the keypresses - which means xwhatsit macro engine is not that reusable. Like, not at all reusable. I do like the idea of the macro having "after keypress" and "after release" parts though.

Pretty confident in getting standard 1-layer keyboard software working in 3-4 days of coding though, including debugging. Need to find those days somehow.
Mostly worried for the USB suspend-resume there. Firmware has a bootloader, so everything will be field-upgradable. But macros, layers and expansion header handling will take time. Especially because I don't have any solenoid boards and not planning to.

So I landed back home late last night, and will fly out again early Tuesday morning. I meet with our metal fabricator friends Monday afternoon to get in their queue. After originally thinking I had already done that via email, they want to meet in person to discuss the MINOR changes I would like to see in the production run. As much as anything, our desire for a new black makes them want me to pick out a new one before agreeing to everything from a cost perspective. They really aren't making much here either, and they want to factor in the cost of whatever we choose if it is a non-standard paint for them (I get it).

Not sure how many are following the "workshop thread", but DMA received our beamspring. FINALLLLLLLY. This was a hiccup on my end. I haven't been around (like at all), so my wife has been nice enough to handle my parcels. I had her mail out a couple of things to various folks, but for some reason she didn't send DMA's out (in fairness to her, I only typically RECEIVE large boxes). She unpacks, discards the box, and leaves everything out for me. She knows if things just sit in boxes, they historically will stay in boxes, and that is a bit of a "hangup" for her. When we finally worked out what had happened, she was nice enough to repack one beamspring and accessories in the largest box she could find (smaller than the original), and send out. Moral... sorry for the delay, but wanted you to realize the backstory.

DMA is having success there on the CommonSense front for the alternate controller. For those that haven't been able to follow why this is interesting... I will attempt to explain without technical details. The legacy xWhatsit (which is still brilliant) relies heavily on hardware (MANY electrical components) to map capacitive sensing back to something modern computers can use. DMA has proposed, and is succeeding at, using software against essentially a single chip to perform the same function. This has real benefits not only now (smaller form factor, somewhat less power consumption by the controller itself, functional flexibility, cheaper to produce, etc...), but certainly in the future since software by its nature is extensible. It's a big deal... if it works!!!

DMA's CommonSense (brilliant name) thread is here if you are wanting to follow. Keep in mind going in, you will learn a lot, but this is a topic that isn't for the faint of heart: workshop-f7/commonsense-controller-bett ... 13988.html

I will let DMA give you more technical details as to the benefits, but wanted to help everyone understand why it is so interesting from a higher level. And understand why we are waiting to produce the controllers since the timing of this was so intriguing. We won't delay much longer... and we will vote, but we wanted to give this the opportunity to flush out a bit to really understand our options
