Hello,everyone,I have some MX switches which I needed to attach to a keyboard.But I don't know where to buy any base (I do only need 2 spots) for a game.If you know please inform me

I don't understand, with base do you mean PCB? 2 Spot = 2 PCBs? Game?

I meant a simple PCB keyboard that has 2 minimum spots for switchs,typed in a hurry,sorry!

Make one yourself and handwire, or order a custom pcb.

This thread will cover everything:

Do you want a keyboard with just 2 switches? I remember someone else wanted something super simple like that once, for a game show. They were making the buzzers! Keyboards are overkill for that.

Are you playing Divekick?

If you want something really small... I would go for one of these CM switch tester. From what I have seen of it there should be ample room to hardware the switches to a teensy or similar and make it a functional macro pad or whatever. I think it would be easiest way to have something very small keypad that is a nice finished product. I may even do that myself for a fun little project.

Neat. My smallest keyboard arrived in PCB form in the mail today…

A prototype 20%.

No,I'm not
About the CM tester,I must make a PCB to make a input device.
About that OneHand PCB,How do I get it?

Well you don't really have to make a PCB. You can simply use diodes and wire to connect up the switches in a 2rows 1column simple matrix and attach it to a teensy controller. If you know soldering well I think the whole assembly would take less than 10 minutes.

Perhaps Chanhien hasn't heard of a matrix or a Teensy. So here's the basics.

This is the Teensy:

It's really small. You plug a mini USB cable into it and you can upload software to run. A guy here called Soarer has some great software to make the Teensy work as a USB keyboard, called Soarer's Controller. Then you solder switches between the right pins, and you have a working USB input device.

For whole keyboards, we use a matrix of switches to simplify the wiring. But for something really small, the Teensy can hook up straight to each switch. The OneHand works that way, but it's a chording keyboard (where you hold several keys down at once to type, like playing chords on a piano) so it's complex to adapt to a simple keyboard and uses different software.

Thanks for the info,I'll buy the teensy controller,is the diode the transparent cylinder part with a orange core?It comes with the red switch so I guess it'd be fine?
