I guess screw tension has minimal impact on membrane performance. The internal black rubber layer has already serve as tension buffer unless you ditch the rubber. I have done bolt or screw mod to several model m and none of them has screws falling out even without the rubber layer. I would say screw...

Thought I'd share some progress pics. Everything's routed, checked dimensions, and it just needs more polish (and maybe a little more design rules checking?) before I attempt to send out the order ^^ I also added some screen print art because a board this big felt like an empty canvas. I think it g...

download and install SwitchHitter. It will show scan code for every key press.

The one I am using is 7mm overall thickness (including solder mask and copper trace) When I order I said 8mm but turns our 7mm but it works perfect.

Permatex Dielectric Grease

any update on the electric paint?

please refer to the pics below and hope this help

Just finished a usb conversion to a TRS-80 model 4P with teensy++2.0 First, thanks very much for updating this thread! Second, I have a Tandy 1000 keyboard and I'd like to make it work with a Teensy. Can you please provide a bit more detail into how you wired up the Teensy and how you wired up the ...

Just finished a usb conversion to a TRS-80 model 4P with teensy++2.0

I was thinking that capacitive sensing might be used to upgrade the ibm model m to nkey rollover. someone who owns a bolt modded model m could experiment with sticking kapton tape over a membrane contact (like how the varmilo switch is done), then using a capacitive controller to detect if the key ...

neat, one suggestion, wish that the components are soldered to the other side, the through hole components can be seen.

xwhatsit installed with 3.96mm pitch headers. this is on a model M

unless your f122 controller has malfunction, I prefer to use soarer converter instead of using xwhatsit. but if you use xwhatsit, better use 3.96mm pitch male and female header for the installation. will show photos on what I did to my model m with xwhatsit and headers.

I prefer to retain the original coil cable and use an external soarer converter like this one. it has locking cap/numlock/sclock leds

simply make a soarer converter with the specific features.

The crystal footprint is 7x4.1mm. Example: ABLS7M2-16.000MHZ-D-2Y-T

I tried 5032 16Mhz crystal with the original xwhatsit model f controller and it works fine without any noticeable issue. the original crystal spec is just a little bit big.

the adafruit 32u4 breakout board is good if you need a lot of IO. some people flash leonardo bootloader with the breakout board but the original adafruit 32u4 breakout board bootloader is more logical,

here is a photo which shows wiring to a teensy2.0

from top to bottom, only 1, 3, 4 and 5 are used and they belongs to the lower row of pin on the blue socket.

hope this help.

this kind of mild oxidation inside the membrane is normal for a keyboard over several years and should not cause any problem. I would suggest you clean the contact area that plug into the FPC socket with mild alcohol or pencil eraser(not the one for erasing ink). strong alcohol will remove the silve...

Few questions: 1. What controller did you use? 2. When changing over to the capacitive PCB, are you using the Model M flipper or Model F? 3. Could you link a seller selling the solenoids? I am using xwhatsit and its solenoid driver. they are assembled by myself. you need to use F flippers as it wil...

my f60 keeps revolving. have just turned it into capacitive buckling spring with customed pcb and xwhatsit. many thinks to iDollar letting me to modify his fssk pcb design. Amazing job! Can you share the gerbers of this PCB? I have the remains of a faulty '2001 Unicomp laying around: scratched case...

excellent !

your measurement for the cut is very important. give a bit more room for your first cut and use rough sand paper to sand down the plastic to fit. use static model cement to hide the seam, use fine sand paper such as #800 or higher to smooth the surface. spray and file until you cannot see the seam....

I plan on cutting my AEK case down to 60%. Can you explain your process further for hiding the cut marks? your measurement for the cut is very important. give a bit more room for your first cut and use rough sand paper to sand down the plastic to fit. use static model cement to hide the seam, use f...

That’s somewhat more pingy than I expected. No dental floss mod I guess? sounds like the iphone mic is quite sensitive. actual noise is not much pingy than the video. no floss mod. Oh man it even sounds great. Amazing work man :) yes it does sound great. feels like typing on AT and some what close ...

Here is a typing test video of this little keyboard. with and without solenoid.

yeah sure, will shoot a typing test of it later. thanks.

This is a super cool! Would you ever make one of these for someone else, asking for a friend.

I would do it for a good friend but almost impossible for someone I dont know.

Turned out beautifully! How did you cut the plate?

I used dremel to cut the steel plate. I used simple hand saw to cut all the plastic. Except the rotor, I dont have any machine tool to do this.
