Contra with Adafruit solenoid and lubed 80g Aliaz

[Walkerstop]

I finally got around to a video of the latest solenoid I’m using in my Contra. I used 2 different ones before this, both were quieter than this one. I think this one is a keeper.

• Switches: 80g Aliaz lubed with Tribosys 3204

• Solenoid: Mini Push-Pull Solenoid - 5V : ID 2776 : $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits (pay attention to the sample circuit that uses a power transistor, you’ll want to do that)

• Some sample code, how I control solenoid: https://github.com/walkerstop/qmk_firmware/blob/mike/keyboards/contra/keymaps/walker/keymap.c

That’s crazy !
Can you feel the click from the solenoid when typing?

I absolutely love solenoids. Where did you mount it? Can you post more photos of your set up?

Two thinks:

• would you mind making a writeup for the truly dumb people (like myself) to be able to add this to their board?
• Add this as a feature to QMK?

@Walkerstop I adore this - I need you to pull together that guide, and I might do this with my CA66 on stream…

How much thickness of free space is there in the ca66? Do you already know it will fit?

pay attention to the

…co-workers who will suddenly find reasons the boss should fire you if you turn the solenoid on

@keyboardbelle

pay attention

I mean, it’s not really for use at work unless you have a private office lol…

@Walkerstop

private office

this seems mythical, I mean I’m familiar with the two words separately, but together…
