cheapino VS cheapis

The cheapino is super cheap: https://github.com/tompi/cheapino

If you're looking for a 40s Ergo Split, then the Cheapino is really cheap: https://github.com/tompi/cheapino/ (though you have to source parts & PCB yourself + soldering required)

Is there a project similar to the cheapino with a similar goal of offering a DIY cost-effective monoblock 34/36 key keyboard?

inspired by the cheapino

Depending on how comfortable you are ordering PCBs yourself, the Cantor (https://github.com/diepala/cantor ) or the Cheapino (https://github.com/tompi/cheapino ) might be a good starting point for getting into split keyboards, both are diodeless, so you only need to solder the switches and use relatively cheap microcontrollers

If money is a big concern, you could look for cheaper style boards like this one designed specifically to be on the cheaper side: https://github.com/tompi/cheapino

Here is the link to the project: https://github.com/tompi/cheapino

I was thinking something along the lines of the cheapis, but not held together by the MCU and made of one PCB.

technically, cheapest for several fab shops is if you can get PCB under 100mm × 100mm (ex. Cheapis and bgkeeb)

If you're looking for something very cheap /u/PM_ME_YOUR_MAINFRAME recently posted their Cheapis keyboard.

PCB: Which PCB is good for me? A margin-space keys keyboard or no-margin-space keyboard? In the 1st photo of the Sweep, there is no margin space between keys. However, Urchin and Cheapis have margin space between keys. I am using Thinkpad X1 Carbon and Framework Laptop. And I am more comfortable with a keyboard with margin spaces between keys. However, I want to know the benefit of the no-margin-space keyboard, and how easy it's to get used to.
