First of all, I would like to thank you for all the boards you make and publish.
I have already ordered several v1.0 PCBs from JLCPCB (they have restocked the inductor as of today) and I'm looking for a solenoid that would be compatible with the driver board.
Have you been able to test it with any ...

Usually the controller chip schematics are public. Use a multimeter to trace back cable leads to what is VCC and GND. For Data and Clock, just try both options until it works ....

Would anyone know of model F spring dimensions ?

Length, Diameter and wire thickness ?

Who are you trying to kid?

The last one sold for 330 euros

Short answer - No you can't

Long answer - The PCB side connector is different by brand, model numbers and so on. The only way to be sure is to check the pin schematics and determine what each of the pins are designated as.

awsome work!

I'm in the process of restoring an IBM 3276 keyboard (wiki/File:3276.jpg) and I wish to convert it to usb; as far as I understand Your design is compatible with these keyboards, can You confirm it ?

Thanks
Luca

It is...

You can order one on your own from JLCPCB.com
Find the Gerber files on this thread, upload to JLCPCB and pay.

PCBs are actually quite cheap, JLCPCB can make them for less than 5 bucks a piece. MOQ is 5 though.

Use this viewtopic.php?t=23406.

There are 24 pins for columns and 8 sense positions for rows on the PCB, that's more than enough keys you'll need (192 keys!).

That one is 5v, so it probably isn't the one that will will want to replace an IBM solenoid. Also its probably going to be the size of a dime.

I'm not sure where to get model F style solenoids, I need some as well. I might have to resort to making them myself :shock:

0.8 mm will allow you to bend it in place to fit the curved backplate.

Well, it's hard for me to estimate because I've used components from variuos sources, which were bought in different amounts, some parts I already had etc. I should make a nice BOM with multiple sources and prices listed. Also the important factor are the outrageous shipping prices to my country ...

Considering that engineering the flippers took ellipse a long time, why don't you just run a GB for PCB and the controller, without flippers ? This way people could use their own model f flippers, if they're compatible with the model m plate and barrels, and meanwhile you could further test your ...

That's interesting. Though I have not done it myself I know it is possible to design a PCB and then have that design made up. Is the same true of a metal plate? I assume a case would be the most difficult part as most cases are moulded and making the moulds has a lot of set-up cost.


Obviously ...

If you don't care about fancy metal cases, then just a PCB, plate and switches is all you need.

Great job Andrei, I am going to do that on my beamspring

In my experience they are similar (if not exactly the same) to the vintage blacks.

JLC is significantly cheaper and can assemble the SMD components for you as well....
