Re: New Compact Beamspring controller available

No, sorry, these don't support Displaywriter. These are a trimmed-down version of the original TH. These only support 'standard' beamspring keyboards, the same ones that are supported by xwhatsit's original beamspring-usb pcbs. But the TH does support displaywriter, and there is at least one person ...

Re: New SMD Model F controllers available

I take it these don't support the F XT? Well, the FXT has an embedded controller on the sense PCB, unlike most of the other model Fs that are connected to their controller via a soldered ribbon cable. I think I have seen people convert F XTs by cutting off the controller part of the PCB, and then s...

Re: New SMD Model F controllers available

Hey guys, A couple updates: 1) I renamed the "through_hole" firmware to "universal" (you will need to update the util.exe too if you update the firmware) 2) I have doubled the threshold offset for all Model F keyboards, and I bumped the number of calibration bins from 3 to 5.

Re: F62+F77 orders now open! New Kishsaver+Industrial Model F Keyboards

To all QMK beta testers: I have doubled the Model F threshold offset from 12 to 24. I expect this to be an overall better value.

So what happens with those low signal value keys when you press them? Does the signal value increase?

Re: Beamspring solenoid driver - Help

5) I see there's no rubber mat underneath the solenoid driver, like my 5251 has. Can you make sure the metal backplate isn't accidentally shorting the pin header pins on the bottom? Maybe add some electrical tape, or just a piece of paper for starters.

Re: Beamspring solenoid driver - Help

Hey!
1) Did you click Store In EEPROM after?
2) Did you try unplugging and replugging after?
3) Does the LED on the solenoid controller light up when you press keys?
4) Do you have a multimeter to check some voltages with?

Works perfectly guys
Good to know!
Nice looking color coding on the wires!

Is there an issue with the second mounting hole position?
I measured out the mounting holes using my F AT original controller PCB, which should be the same as for the F122.

The blue modern 3.96mm card edge connectors that are often found on ebay/aliexpress, and are used for converting Beamspring keyboards are often a lot looser when compared to the original connector. They are often so loose that some columns/rows don't make proper contact, and even vibrations can knoc...
