A cheap, open source 45% keyboard

Prototypes

Last gen prototype using tg3 as a base.

Summary:

Basically an open-source, cheap 45% keyboard. You can use parts from a tg3 keyboard for maximum cheap, or use standard ansi keycaps.

Features:

*Staggered 45%, meaning an extra column over standard 40%.

*Multiple supported layouts, including split spacebar.

*QMK compatible.

*Driven by pro micro, easily programmable and cheap.

*Uses standard sized keycaps that you could find in any set.

*RGB underglow, used for layer indication and caps lock.

*Design for pcb plates.

*Optional 6° angle.

The base (TG3):

You can either use a tg3 as the base for this, or use your own parts. The advantages of using the tg3 are price and sturdy-ness. With a tg3, you can get Cherry blacks, uniform dcs keycaps, a steel mounting plate, and an aluminum back plate, all for $15-25. If you were to buy the absolute cheapest keycap set ($6-8), the cheapest switches ($5 for 50), an fr4 or aluminum plate (~$10-15), and use a scrap of something for the back plate, it'd cost a bit more, and you'd be dealing with low quality parts. Granted, it takes some work to desolder and mod the tg3.
